My "minimalist" turbo crx **just ran 12.9: video**
Finally took the plunge...
First off, I'd like to thank Justin and Donnie for welding. Couldn't have done it without you guys. Also thanks HMT, wether you realize it or not, there's a LOT of good information here. Too bad the search doesn't work sometimes.
So, the list:
d15b bottom end
d16y5 vtec-e cyl head ported/3-angled/milled .028" (~10.4:1 CR)
OE gasket w/ arp's
skunk intake manifold w/ 60mm t/b & heatshield gasket
exedy performance clutch kit & 12lb. OE flywheel
dohc ZC trans w/ intermediate shaft
EG radiator w/ pusher slimfan
jimfab mounts and crossmember
Spare Room Products battery/cables/battery tray
subaru tdo4 wrx snail
CSaddict superwarped manifold(lol don't worry, I got it fixed, and not that I could do any better)
dsm 450's and BOV
2.5" downpipe/chargepipe
skyline rb25 intercooler(or so I was told)
obd-1/Crome/p28/zeitronix
mcmaster/summit/home depot oil lines
First impressions:
Pretty quick. stock internal wastegate on this thing is set at 7psi. Creeps to 11psi @7200rpm. SCARY with compression. ~93oct. 1.5* per pound timing retard w/ 9.5* total timing @ 10psi. Still using vtec-e setup. QUICK spool. 7psi by 2400rpm. No overheating issues. Oil feed line has a regulator/gauge built in. Apparently STI turbo is a direct swap. No smoke. Haven't come up with a crankcase evac system yet, but a electric vaccum pump/catchcan seems the ticket. Unordinarily quiet for open downpipe. Not sure why, but I'm not complaining. 2nd gear burnouts are fun. Will port EX housing and wastegate to help alleviate boost creep(hopelully).
I wanted to note that subaru uses a banjo oil feed for some of their turbo's. In order to come up with an oil feed line, order a brake line hose from summit with a -3an fitting on one side and a 10mm banjo fitting on the opposite, and a banjo bolt. The thread pitch of the banjo is 10mm diameter x 1.5mm pitch. This was some of the hardest info to track down,for me, so there it is. I'm pretty ---- about how everything went together. Efficiency was my driving force.
Planning on shooting a couple video's this weekend. Justin, Donnie, you guys down?

Re: My "minimalist" turbo crx
There's nothing wrong with that CR. That's like boosting a stock B16 which boat loads of people have done. It's just not slacking on tuning or running shitty gas. Looks nice but you should of kept it yellow instead of that 88 crx si silver that it looks like. Or atleast keep some of the trim black instead of having the whole car just completely silver. It's too much. The wheels are
