Took my car to the dyno today. It did pretty well it made 327whp on a dyno dynamics at 14lbs. Had some problem with boost creep.

Drove the car home and about 1/2 way here it starting missing/cutting out when it started to hit about 10psi or so. It just all of a sudden started doing this.

Now when we had it on the dyno it did this and we regaped the plugs to 32. It did great after this! The plugs are NGK 6es's. I just wanted to know if it could be the plugs. I’m going to be taking it back to the dyno again tomorrow.

My set up:

RB25DET

JUN Intake manifold

90mm throttle body

550cc Low impendence top fed injectors

Garrett GT3582R

Tial 44mm V band waste gate

Apexi SAFC II

Apexi ITC

Walbro 255hp fuel pump

Aeromotive fuel pressure regulator

3" ss turbo back exhaust

FMIC

Z32 MAF

Any relative information would be helpful!!

get on the car as in "more boost"?

more boost = more air flow etc etc..

try budget option of taping up the coil packs.

search for "Tape+up+coil+packs"

it costs you 30 minutes and the cost of a few rolls of good electrical tape.

should give you some time to buy splitfires or something.

also, when you say you gapped the plugs down to "32" what measurement is that?

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
