Sweet. I know there is a boost leak because I left the last charge pipe off from testing for spark. Didn't think it would matter at idle or slightly higher since it's not making boost yet...and the engine is an OEM turbo SFI DOHC 183ci (3.0L) gasoline engine. Once she gets a little air through her I think she'll run real nice.

Are you using the stock MAF setup?
If so the MAF should be before the turbo. Beflcause of this the ECU thinks its suppose to get a certain amount of metered air. If the motor is getting more/less air than it thinks its getting, it will idle funny and run funny. With that big of a boost leak, the ECU will force a super rich condition leading to fouled plugs and crazy sputtering.

It's a map setup. (JDM) It's already doing a lot better. I'm slowly letting her warm up and it hesitates a little before winding up, but doesn't stall anymore.

Since no one else has said it...........
After 10 or 15 grand, that will descimate all. We might even have to overnight parts from Japan.

J-Spec OBD1 conversion to US-Spec OBDII conversion:
New MAF sensor and air filter setup physically installed.
New injectors are bolted in, but I'm waiting for the proper injector plugs to continue. This pic is actually from before I swapped the rail. USDM injectors have purple plastic.

OBDII conversion complete. I had 4 codes, but all were related to devices that are no longer there. Resistors have been wired in and I will be clearing codes tomorrow. I expect more to show, since I still need to finish fabricating the exhaust and I don't have the rear OXY sensor wired to the new ecu yet.

Down pipe and exhaust setup is built and complete.
I have one remaining code that a resistor will take care of, I'm expecting an O2 code to show up, and for some reason she won't idle now and is shifting REALLY hard. I'm on Supraforums and going through factory repair manuals (both volumes) for a solution. I've also received my 3 fan setup from Dirtbound. So close to legality and daily drivability now...

I've been really distracted with a Top Diesel project that sort of fell into my lap, and the race is this weekend, so it's hectic...however I did manage to get rid of the last Obd2 code and no longer have a CEL! Still need to wire in the rear O2 and fix a couple of safety inspection gigs. ANyway, some of you may be interested in the distraction I've been working on:
