Rb25det R33 Injector Upgrade

[boostn0199]

Hi, Im looking to upgrade injectors for my r33 which will need to get me to 300kw, now im left to choose from s15 injectors, a set of aftermarket new 550cc injectors or hi flowing mine. What do you guys think is the best option and what have you had experience with and where can I find the best prices to get some, thanks.

If your power goal is 300rwkw then a set of Nismo 555cc with do the job.

But here is an absolute bargain: http://www.skylinesaustralia.com/forums/Fo...ec-t275632.html

The best option is to read.

Hi-flows are super well documented

S15's - same deal

And as for new ones... there have been half a dozen threads in the last month in 550's (and also 740's).

End of the day, it comes down to budget. If you want it done on the cheap - 2nd hand/hi-flows. If you want unquestionable reliability you buy new.

Simple.

just been through this and will help making a mistake. just go the nismo 555. not saying that the s15 injectors are bad but had strips torn of me by my tuner for buying them. they are a pig to tune and and will not be as good as the aftermarket injector. mine have been flowed out to 600cc. he said that they have to be tuned as a 480 at the bottom and a 600 at the top of the maps.

Well i got 740cc highflowed stock injectors and im doing 230-240kws... with a power FC and its runing excellent.

I have a hiflowed set making 300+ rwkw no problems, they idle like factory and were a peice of piss to tune.
