Revving Boost Issue

[driftindustries]

Hey all!!

Ok so story goes. - Car is fuel as, and wont rev correctly just spits and farts etc..

1997 200SX S14 - Car

RB20DET Engine & Box

- Forward Facing Plenum

- T3 Turbo

RB25DET (Series 1) Conversion Loom

Have Changed, AFM, Plugs, Injectors, Coilpacks, O2 Sensor

Any ideas ??

Does "fuel as" mean rich? Injectors, AFM and ECU need to be a sensible set.

[chiksluvit]

What ecu? Happened after conversion or it has been ok until recent?

[Ben C34]

What injectors?

[Ben C34]

Just a bit of extra info.

T3 turbo does not describe the turbo at all.

[chiksluvit]

Too scared to say ebay turbo or everyone will have a go at him

[driftindustries]

Havent ran correctly since conversion, stock ecu & stock injectors, turbo is garrett gt3272

[chiksluvit]

Don't know that turbo but an aftermarket turbo with stock ecu is
How long have you had it for? @ what boost and for how long? Compression test?
I know stock rb20 ECUs don't handle high boost well and could lead to destroying an engine. I learnt what pinging sounds like with a boost t in an r32 gtst 10 years ago

Issues from cars with conversion done are really hard to diagnose online because so many things are customised
Ie it could be an injector plug that was not soldered/ joined properly or a bit loose since you used rb25 loom which has side feed plugs and rb20 uses top feeds hence different plugs. Or many other things
Definitely more info needed

I thought sr20 from s14 would be a better engine in the s14 than an rb20 but anyway

edit: read again realised you said havent ran correctly since conversion. check wiring and timing i'd say
