RB20, GTR cams, injectors, Z32 AFM, std ecu. OK runs

[Ahh32]

Just finished rebuilding my RB20 with GTR cams & injectors, 044, Z32 AFM, chipped ECU.

Put the engine in on Monday, (AFM connected to TB) went to start it, would fire a couple of times then die. I thought it was something wrong when i modified the wiring for the GTR injectors, stuffed aroung with them for 2 days. I found my std chip for my ECU, put it in, fired up staight away but wouldn't hardly run under 2000rpm (same prob as BBenny had), and wouldn't hold a steady throttle position.

It was blowing a lot of black smoke (richness). pulled off the hose for my BOV (to lean it out a bit), less smoke, revved smoothly & OMG it even idled.

I still blows a bit of smoke so still a bit too rich, but good enough to get the car to your nearest tuning station.

Just thought i would share that experience that a Z32 AFM & GTR cams & injectors will work until u get it tuned properly.

Haven't checked timing or anything else as i have to pack to go to Brisvegas this weekend for a wedding.

good luck ahh32. i look forward to hearing your results.

since then i went back to std cams with adj pulleys and the pulleys alone made a big difference, today i fitted a pre-tuned chip and my car feels like a damn rocket!

so i imagine yours is going to be awesome!

i thought u might be the first to reply. i think the running in stage is going to annoy the shit out of me, ohwell.. i guess my pre tuned chip wasn't pre-tuned quite right.

What GTR injectors did you put in R32,R33 or R34 GTR ones? and cams from what GTR.Thanks

So its a fresh engine and you are letting it run rich???

[sky30]

Yeah, i agree with joel, when it runs rich the extra fuel can wash the oil off the bores, not good at all for running an engine in. I would put the stock pump, injectors and ECU back in just to run it in, then upgrade. Hate to see a new motor fkd.

howzaboutanupdate

also .. im wondering with the cams in .. did u have to reset your valve lash .. if so .. to what thou?

thanks

[Ahh32]

first off i have not driven my car over 5km/hr yet,

second, it wouldn't start the other day, igniter ****ed.

Joel- i am well aware of that fact which is why i am trailering it to a dyno and tune. all free

R31- R33 injectors, R32 cams

Angry- yes, it took mw 2 weeks finding out the prob with my car, making my front pipe, modifying FMIC piping, re-trimming interior. etc.

RB20's run hydaulic lifters not solids like GTR's so no adjustement.

I may update this thread next week after i get my igniter & car tuned

I would like to see the difference it makes with the R cams ....

have a set here that i would like to fit if the gains are worth it :aroused:
