:::RHMT::: Real Home Made Turbo

So I guess this is the new HMT home now, huh? Well, here's my build again...
First off, I'm from norway, so my english sucks
Second, I'm not cornfuzed, that guy from the old site that everyone seemed to hate
I was lurking on the old forum since feb 06 and tried to suck up as much info as I needed to put my own turbo system together. I didnt know shit about turbo's or cars before I found this site, so this is my first turbo setup and motor build, but definately not the last. I really enjoy the idea of getting boosted for less than the price of a b-series header and be faster 0O
Anyway, here's some eyecandy:

Then onto my first turbo setup:
D16Z6, rebuilt with stock stuff
t3.42/.48
FMIC, backdoored
Homemade mani, charge pipes and dp
eGay bov, clamps and couplers

Something weird on the dyno. Had to pull way more timing than what I've seen others do. Tuned with crome free + freelog

Went to the circuit, and here's the result... Dont know if it was because I had hit the ground a couple of times with the dp, too high egt because of all the timing I had to pull, poor welding or just too thin walls on the mani... Some bracing action...

So I bought ectune, already had a wb, made some detcans and went for it. Havent tried tuning myself before, so it was fun :p I'm still not sure on what knock sounds like, lol.
Some vids from the circuit:

So the stock block actually survived the season, I'd never would have thought that. I'll be using the block for some vitara's and fjt's custom i-beams this winter :)
Fartcan is gone, had to route the dumptube into the exhaust to pass inspections at the track. Also got a new turbo, a 46 trim t4/t04e with a small .48 a/r exhaust side. Hopefully it'll spool about as fast as the saab turbo, without the choking on top.

Ported a little bit in the oil pump. I reused my old oil pump so didnt feel like filling the blind entrance behind the hex plug with epoxy.

Oil cooler was a pain in the ass. Had to move the radiator to make room for the fittings. So I have like 1mm left before it hits the dp.

I HATE SNOW! Just waiting for the spring now... At least with the lsd I'm not getting stuck. Car seems to work fine, a little diesel'ish sound but I guess thats normal. I warmed it up and raped it pretty hard for the rings to seat, I'll just have to put some miles on it now before I take it to the tuner...
Edit:
So I editet my whole post now. Hope you're happy RICK P :-*
-
nice build!
-
Sold post love the pic's.
-
very nice build. And yeah, the vitara builds always sound a lot more like a diesel. I have a friend who did a vitara build on his d16z6 and turbo'd it, the thing sounds awful but has decent power.
-
I'm lovin the bucket for pulling the motor. I have done that a couple times, the trick is to get the bucket high enough that it is at its furthest out point in the arc of travel, or it is always trying to pull the motor out into the firewall.
Solid project, good to see lots of pics.
-
cant tell from the pics but are you running a flex pipe?
-
NICE
-
that is bad ass i track my car too!!
dude how much dose it cost to go out on a circuit for a day?
and where you at ? somwhere in europe?
-
awsome post. looks like a pretty good build you got going there. looks liek you only spend money on what was needed and didnt try and impress the HT crowd by buying uneeded baller parts, nice. but i would suggest you look into maybe a cheaper engine hoist ;)
-
wait a fucking minute! do you have a pit in your garage?
-
the grease pit in your garage is bad asss
btw did you rubber coat the whole under car?? NICE WAY TO KEEP HER ALIVIE
i live in california and we dont have those rust issues here but thats nice what you got going there

Getting the motor out was easy, getting it back in was a bit worse, but it worked out OK. I did cheat a little with that chain thing you see in the pics, I dont know what is called... I lowered it straight down with that...
cant tell from the pics but are you running a flex pipe?
+1 our gonna want to get one if not.
Solid build though. You look like a pretty good driver. It was funny seein you overtake two wrx's back to back. I wish I had a track like that close.
The flexpipe is there, but its not easy to see it in the pics...
Here's my DP:

I think my manifold cracked because of shitty welds, way retarded timing (lots of heat) and my first DP was a bit off, so it hit hit the ground sometimes... It stopped cracking after I added the braces :)
Those video's were from my second trackday overall, first one turboe's so I really dont know what was up with all the others driving like that. I think they just put way too much money in their cars and are afraid of using them or something. I thought they should be way faster.
that is bad ass i track my car too!!
dude how much dose it cost to go out on a circuit for a day?

You should bring the camera next time! :yes:
I live in Norway, Europe. The trackdays cost something like $30-120, it all depends on who's arranging them. I'm member in a few different clubs to get discount, though, it pays off ():)

Yeah, the feeling of passing a ricer with a ten foot wing in a stock looking civic is fucking sweet! Now it sounds like a diesel at idle in the pits too, awesome!
the grease pit in your garage is bad asss
btw did you rubber coat the whole under car?? NICE WAY TO KEEP HER ALIVIE

I love my greasepit :noel: The stuff under the car is like really thick oil. Its a PAIN working under the car, the stuff gets in your hair, in your face , neck and everywhere, and wont go away for days. But it keeps the rust away... I really hate the winters with snow, salt, rust, etc... Almost every car from the 90's and back are rust buckets. Living in california has got to be great.
-
Dude you rock. I kinda wish we had track days around here. Maybe someday I can hit the Nurburgring and fuck Sabine.
-
Wow, sick as fuck thread man. Your build has inspired my build. Great track car!
-
yo that shit was fire. i enjoyed watching the videos, made me want to get into this shit. good stuff
-
Can you do Norwegn (sp) Flick with your car? ;D :evil: ;D
-
Dude you rock. I kinda wish we had track days around here. Maybe someday I can hit the Nurburgring and fuck Sabine.
There are quite a few people from here taking the trip down to the ring, but I've heard so many stories... If you wreck your car, they make you pay for the towing, fixing of the fender, and also the money they loose for closing the track when they fix it. I would have to drive very carefully, so I dont really see the point of taking that long trip... Maybe one day.
Sabine's awesome. Its funny to see her overtake bikes in a ford transit van, lol.

i remember you.
cool build, welcome to the site
Cool, I've made something to remember me about :noel:
Thanks!
-
Can you do Norwegn (sp) Flick with your car? ;D :evil: ;D
Lol, its Scandinavian flick ;)
Well, havent really tried in this car, being a fwd, and that I dont rally it. :)
If I have a rwd winter beater I'm trying all the time. Sometimes it works, sometimes it doesnt. I need to get a rwd or 4wd beater till next winter to practice more... ;D
-
nice build
-
Glad to see you made it over man. And I still love the heatsheild. Most of the heat is always coming out of the manifold and turbine.
-
Thanks, yeah, those are seriously hot... I saw the cocking pot turbo heatshield in that other thread witth the Escort, so I'm thinking of doing something similar. Looked great, and cheap O0
-
what LSD did you run on videos?..
nice to see who like runs in roadracing races.. :yes:
-
No LSD in those videos, just the stock open diff. Havent tried the mfactory lsd on the track yet, one of the things I really look froward to this season :)
-
let us know about any update!
-
There's a few things since last update, but noting big...
Installed a solenoid for the ebc feature in ectune. I love that thing. Boost by gear FTW!

And yesterday I went to the dyno. Not so happy about the whp numbers, dont know whats up really. We tuned it up to 15 psi, and tried 18 psi, but the torque falls flat in the end, so after 6000 rpm, 15 psi and 18psi put out the same number. I mean I know the combination of log mani, .48 ar exhaust housing and full 2.5" exhaust makes a shitload of backpressure, but I was hoping for 250whp at least... I did install a camgear before I went to the dyno, and put the engine in correct mechanical timing, like JD were talking about in a thread on tho other forum, but I didnt have time to try other settings. That really bugs me now, cause I would like to se what happens with a little retard of the cam, but it'll have to do for now. I'll retune some time during the summer. Torque is great, though. So I think it'll do pretty good for my use :) 318 nm = 234ft-lb

Went to the track today for the first time this year and had a blast :) Here's a couple clips

However, my cooling system doesnt do what its supposed to do... Most of the time I just had to drive around on 7 psi, because after a couple laps I would overheat on anything higher. I've tried quite a few different things, but I just cant seem to make it efficient enough. One solution would of course be to redo my whole setup and fit a fullsize radiator in there, but I'd rather not, because of the work and money that I'm not having time or money for right now...
This is how it looks today

My thoughts:
I made the fan shroud to let the fan draw air through all the surface of the radiator. However, in high speeds, the fan is doing nothing compared to all the air that is thrown in the face of the radiator, so is this shroud just doing things worse?
I dont have the stock bottom plate. Is this disturbing the air flow through the engine bay in some very bad way?
I use a Mishomoto radiator. Would buying a "name brand" radiator do anything other than hurting my pocket?
I tried shimming the hood, to let some of the hot air out, but it didnt make much of a defference, other than making a fucking sauna inside the cabin during a heat :p
Any help would be much appreciated!
Oh, and I finally got to fix my "sticker" O0

do a compression test. if ur car overheats like that chances are ur headgasket is toast. i ran into the same problem with my build single cam back in the day. turns out the headgasket was junk. i put a new one in and it solved the problem. i even hacked up my bumper like u did thinking it would help.;
def investigate the headgasket tho could also explain ur shitty power numbers.
-
if its not the HG try to block off the open side of the engine bay to force the air through the rad... the air will take the path of least resistance
looks fun!
-
Just did a compression test and it turned out good. #1-3 160psi, #4 165psi. No oil in water, no water in oil, no pressure in the water, and no smoking or oil on the plugs, so I dont think its the head gasket.
If I block the other part of the intake, I would have to block the first half of my intercooler, dont know if that is a good idea?
Forgot to mention, there is no sign of overheating with normal to hard driving on the road. On the dyno the temp was right on through the whole session. Its just after a couple hard laps on anythin above 10 psi there's a problem. If I run 7 psi, I can do 6-8 hard laps before I need to take it easy.
Anyone have experience with running clean water and water wetter? Does it work any better than water + antifreeze?
-
ok i was under the assumption it was overheating in boost all the time. if the comp checks out ur fine.
when i had my issue 1 and 4 cyls were 175 and 2 and 3 were 145.
water wetter works well. do u have a slim fan? if not id thorw a fal fan or some other type of high cfm slim and and wire it to run constantly
-
You are overheating because there is zero airflow across your radiator. I'd ditch the oil cooler, or mount it in a lay-down capacity where it stops fucking up the radiator's mojo.
Putting your engine into time is all well and good, but next time on the dyno try to retard the cam a degree or two. That pushes the cam's powerband upwards and boosted small port D16 really like that.
-
I wish I didnt need the oil cooler, but without it, the oil got so hot that I started to loose pressure after some laps. Not sure how ther bearings like temps at ~280F+ either. I will look into moving it to another place and maybe add a fan or something to get airflow over it. Or find a way to mount it lay-down, if I figure out how to get airflow when mounting it like that :p
I have a slim fan, but I think its some china-garbage. I made a schroud for it, so hopefully its doing some use. I'm going to borrow a fal fan from a friend to test out if it makes a difference.
I figured I should do some logging before I start to buy stuff. Pull out the thermostat and log outside temp and coolant temp when cruising on a flat road. Then start with the easy and cheap/free mods like better ducting, water wetter etc. I've also made a ghetto water sprayer system out of a windshield washer reservoir/pump and a nozzle from an old spray can I want to try.
I actually retarded the cam two degrees a couple of days after I got home form the dyno. Feels like it doesnt die off as bad, and I had to add some fuel in the top to keep the AFR curve flat, so hopefully the powerband is a little better. I think the timing still needs lot of work, though. I think its way retarded. That might have something to do with the overheating too...(?)
-
You could run with a thermostat with 2 to 4 6mm holes drilled to flow some water alll the time. :yes:
Does it make a difference when you run the heater at the same time?
When I drive in the summer I use straight distilled water in my cooling system and with antifreeze in the fall and winter.
Could help to use some water wetters too. ;D
-
If you can keep your coolant temps down now, I'd put on a VX/GSR oil cooler on the thing. Track temps for oil can get past 240F, while coolant stays below 210F. Oil should definately stay in spec if you're passing all of it through a 200F cooler. If you really want, you can put an additional rad for that coolant line before the oil cooler. That would help with both coolant and oil temps.

I think the Intercooler-on-top-of-the-oil-cooler-on-top-of-the-radiator may be a little too restrictive. In fact I was thinking that at the beginning of your post before you said you were having an overheat problem.
Try reconfiguring things (the oil cooler first,), and/or maybe a block off panel for the open space next to the radiator too.
-
I removed the thermostat today and got a surprise... It was some sort of low temp thing with a fucking 25mm hole in it, the stock one I had laying around has a 32mm hole. So 40% less flow than stock... >:(
I did a some testing with no thermostat and managed to get the temps down 2-3 Celsius with some ducting. Didnt get to do all the stuff I had planned, so hopefully I'll get another couple degrees tomorrow.
I'll give it a try, and if it doesnd work, I'll move the oil cooler and add a drop-vent in the hood behind the radiator.
Wished I thought about the gsr cooler before, but I cant stand working behind the block when the motor is in the car, and I dont have time to pull it now. It sounded like a really clean setup. Might have to look into that next time I rebuild the motor, which might be soon (never know)...
-
Or find a way to mount it lay-down, if I figure out how to get airflow when mounting it like that :p
Racecars and some OEMs have done that over the years. It's really not a problem since a lot of air passes underneath the car, but some people have to see it done before it clicks in their head and they get the idea.
-
just like jd said, it looks like there's not a whole lot of air making it to the radiator...even those hoses being rerouted might make a little difference....your fan is pulling towards the engine, not pushing air throught the front, right? If it were pushing and you were driving fast, the air would remain virtually static within the radiator.
Excellent build and thread

Is that some kind of racers secret or something? I've been googling for an hour now and cant find shit.
Anyway, I put the stock splash shield back on and the temps suddenly dropped by 5 degrees Celsius rock steady when cruising @60 mph. Seems like it does quite a bit for airflow under the hood. I've also zip tied the hoses more out of the way and used half a roll with duct tape to direct the airflow a bit more. Going to the track on thursday so I'll have to wait till then to get the answer if its enough.
The fan pulls. Wired it wrong once, and the car overheated when just driving normally :o

Funny, google pulled this right up.

They don't have google in Norway JD :'(

Lol, I still cant find shit. Thanks JD. I have some ideas if its nescessary to move it noe. Think its possible to squeeze it in behind the passenger side front light too, and just remove the light at the track.

mfactory, nice. love to hear more about it
my obx is holding up just fine as of yet
