[R33RWKW]

Hi Mate, I made 213RWKW@14psi (std turbo)(before my new mods were finished )using the following mods:

Full rebuild - RB25DET (headwork inc)

Bosch 044 Fuel pump & surge tank (in boot setup)

Monza fuel 1:1 rising rate regulator

Apexi SAFC 2

Apexi GT Spec FMIC

Jasma 3.5" Turbo back exhaust system (4"tip)

K&N Pod filter (the large one, can't remember what model)

HKS SSQ BOV

Cusco Oil catch can

Everything else was std (injectors, coils, turbo, manifold, AFM etc..

I have memories of other people posting better power figures while using the std injectors (with different mods to mine though) so do a search & you might find some more info.

with stock injectors, 250rwkw is on border line

with upgraded fuel rail then prolly a tiny bit more

but is it really worth it? s15 injectors are 480cc (vs 370cc) and will be fine and can be had cheaply

s15 dont suit neo rb25 as far as i can recall

s15 suit rb25 r33 fine tho, direct fit, get them from nissansilvia forums, lots of guys sell them when they upgrade, just gotta find 6.

Don't mean to detract from main topic but what price is reasonable for 2nd hand injectors?

I was looking at upgrading injectors on my GTR as part of a number of upgrades. Was not sure of the buy second hand and then spend $20-30 each injector to have it rebuilt when I came across a guy in US selling via EBay. (Risks aside of buying from someone not local), is the following a good price for RB26 injectors? I would put up what the price was for RB25 side feed but did not see one specifically for this. ( Has SR25 side feed 800cc for set of 6 US$435)

Nissan 800cc Direct Fit Top Feed RB26DETT INJECTORS EBay7993894339 Buy now US$360

sent email and will do 1000cc for the same price

Sorry mate, just checked my old CAT in the garage, it isn't standard it is 3.5" also. So the exhaust is 3.5" Turbo back. The fuel regualtor was around $100 on EBAY, but I do advise you to spend a bit more. I had to put a SARD one my car for it's latest mods. (now the car is 285RWKW & will be 300 soon) (Garrett GT30 Turbo).

I paid $318.20 for it to be supplied and fitted. I had pretty good fuel economy with the SAFC 2, but it all depends on how you drive it.

I could get around 450km per tank driving "normally" or only 250 to 300 when planting the foot. I still can get 400 - 450 km to a tank now , but only if I drive like a Grandma. B) BUT - Only 200 km per tank if I want yo hear my Screamer pipe

Hope this helps.

Cheers
