Z32 Injectors Into Rb25det

[rs73]

I haven't seen anyone fitting these on and everyone seems to be going straight to 550cc aftermarket injectors when upgrading their injectors due to new turbos.

However if one would want something in the low 200rwkw power output, would a Z32 480cc injectors fit onto RB25DET and do the job just fine?

[paulr33]

stock injectors should do you for 200rwkw easily.

im peaking 190rwkw ish and i usually see around 80% inj duty at max load.

s15 480cc manual injectors are a direct fit however

I was peaking at 80% with 210rwkw.

to make 200rwkw, stock AFM, stock injectors, powerfc, exhaust and FMIC is more than enough.

[rs73]

Well I've been close to 90% injector duty for 192rwkw with std turbos.

With a 2535 going in, I'd imagine something has to be done in the injector department. Not sure if simply fitting a Nismo FPR will give a bit more room?

i read in a hpi magazine that you can use rx7 injectors... not sure what year model though... the article was talking about tuning a gtr to a budget...

also one quick question how do you find out the duty cycle of the injectors

[GTRgeoff]

SG just look on the HC for the PFC to find duty cycle.

Rianto, sounds like a problem with the fuel pump or delivery. I was running 85% @220rwkw using a malpassi rising rate adjustable reg. I also have a GTR pump.

yeah 216rwkw with 90% stock pump injectors and reg. Looking at an upgrade of all soonish i think

Space Goat - If it's the gtr, I think they have different injectors for RB26 compared to RB25. They normally won't fit vice versa, but I could be wrong as I heard someone using RX7 injectors as well but not sure on RB25/26.

Geoff, I have a Bosch 950 installed in tank, but still with a std FPR. So I'm sure there's no problem with fuel pump, should I upgrade to a Nismo FPR or equiv? RPM set my boost at around 10 or 11 psi as I told him I don't wanna blow my std turbo just yet while I'm looking for a HKS2535.

race_snooze: that's a good number for a std pump & fpr. what turbo n boost u ran?

PS: I found that the forum didn't notify me at all when u guys reply to my thread.

i just had some work done to my at uas with standard injectors, walbro pump and fpr using power fc and new turbo. it pulled 261.3rwkw with almost max inj duty 90%

rs73 - My car was running fine with the Stock R33 injectors provided you have a bigger fuel pump for the returning.

with a GT2530 , standard regulator, FMIC, the usual upgrades and aftermarket computer was about to achieve about 260kw at the wheels with about 93% of the cycle so would still have alittle left to push it too.

It's all about the tuning. you can make the most of the tuning and at the same produce enough power for a reliable engine as well.

show us the dyno graph. have your injectors been high flowed? power seems to high for stock injectors.

[rs73]

Does anyone with those power figure knows if it's done in shootout mode? My 192rwkw was not done in shootout. I was told it will actually read higher in shootout mode however I don't know by how many kw higher.
