UPDATE car has a JWT sticker on the ecu. Says it is tuned for z32 maf and 756cc injectors. May have to give them a shout about it. Or maybe just call Shad.


I just picked this car up on Saturday and being completely new to sr'd 240's I am trying figure out what is causing my trouble. I believe it needs a new tune but could you guys give it a look over for me. Modifications are listed below.

Engine Modifications:
Redtop SR20DET
SC61 Turbo
ICHIBA Turbo Manifold
MSD 72lb injectors
JGY Fuel Rail
Greddy FMIC
Greddy Type-S BOV
Greddy Oil Catch Can
Z32 MAF
Walbro 255lph Pump
Fuel Pressure Gauge
Blitz Nur-spec exhaust w/ flowmaster straight through muffler has a cat converter on it.
Earls Stainless Steel Clutch Line/Bypass
Greddy Profec B-Spec2 Boost Controller
Apexi turbo timer


-- Turbo manifold, Z32 MAF, ECU Harness, downpipe, igniter resistor are all fairly new.



It feels like the car is bogging down once it hits 4k or so rpm's other then that she purrs like a kitten. Any help would be appreciated as I am ready to roll.

I would recommend searching through Zilvia or NICO for an answer. There is a fairly long list as to what it could be. It would also help if you could be more specific. Does it sound like it is breaking up because of too much fuel or not enough fuel? Does it smell super rich or what?


Also what engine management are you using? That is a pretty significant modification left off the list.

There in lies the problem. As far as I know it has a "tune done" and the blitz boost controller. Sounds almost like it is breaking up because of too much fuel but doesn't so much smell.

I may have to take it to a shop at some point and have them do a look over or someone who has a little more knowledge then me. F%&k!!!

What was it tuned with? SAFC? AEM? If you don't have anything plugged into the harness and the ECU does not have a sticker on it saying it was a ROM tune from someone with certain specifications on it then it would make sense that it runs like crap because that means it's on a stock ECU.

alright so I will be looking for some of these things tonight when I get home. Thanks for the ideas.

could also be a maf problem or the wiring harness isnt installed correctly but there is a long list of problems it could be. good luck gettin it worked out.

I do not like the sound of that. Do you know anymore history on the car? Does it have some sort of tune? Just wondering as I have very little info on the car.
