Alright, finally got this thing in the garage and started ordering parts



Parts on the way:
- action clutch twin disc
- used eagle ls rods / cp pistons 81.5mm 11:0 c/r
- 81.5mm hastings rings
- devcon for filling the block
- supertech valve springs
- -12 an fittings for valve cover
- arp head studs / rod bolts
- blue gates timing belt
- gsr water pump & oil pump

Going to be made:
- top mount divided t4 manifold
   - either dual 38mm or 44mm wastegates
- straight 3Ē exhaust
- intercooler piping

Hoping you guys have some suggestions:

Is it ok to vent valve cover to exhaust? I know this is common in the big block world but itís typically very close to where the exhaust exits the car. I really donít want to deal with a catch can so would prefer to vent the valve cover and block to the exhaust (around where the cat would be) with -12 lines.

Ignition system: Cheapest way to support 7-800 hp without going coil over plug? Iíve looked into msd blaster coils and the like but donít have any experience going down that route.

Which fuel pump(s) should I use? Was thinking about running a -8 feed line and then using the stock feed as a return. Planning on running e85 and going with bosch 2200cc injectors. A friend was kind enough to donate these to my build but I can buy something else if there isnít an ideal combo here:

2 walbro 255ís



Bosch 044



DW 350iL



I was thinking both 255s and the 044 based on this chart:



What am I missing / what's the weak link for 7-800hp? Iím assuming the stock valves and stock cam/intake manifold need to go. Turbo is a Borg warner s300sx3 - 66/73mm, twin scroll, t4 & .91 a/r. From what Iíve seen in other build threads it should get me in that range.

B16 head on top, GSR head on bottom



GSR head



Vintage AEM tru time cam gears



One thing thatís unfortunate about this GSR head are these grooves in the cam. Both cams have similar grooves, but Iím probably going to use it anyways



Cracked retainer from the B16 head



Inspecting everything



Rims/tires Iím trying to sell right now to get slicks and skinnies



Cut bumper support



OEM bumper with VW mk3 lip



Took a dremel to the bumper



Much better



Going to do a sheet metal front end like this



Good representation of how much more room there will be





eBay special 50mm BOV and 44mm wastegates. I did research on the yellow bullet forum and these seem to be pretty reliable for the v8 guys, so figured we'll give em a shot



4 port boost solenoid



Action twin disc



Glad that I'm finally starting to get somewhere  8)

my ebay44mm was a total pos.  it works but none of the clamps fit right and leak.  The nut holding the top on was total shit. the valve or the valve seat was too short to seal.  good thing i can weld and machine.

Really coming along!

I have had 2 china 44mm gates on the crx for the last 5 years. I recently had a vs racing 44mm in my hands and they are a world better.
