Sr20 injectors

do SR20 injectors fit in a N12 jap spec manifold, because I found some on ebay still fitted to there original fuel rail. also does any body no what turbos were used on R32 GTR,S , found some cheap ones suit rebiuld, may come in handy later.

i wouldnt know if the turbo would be any good cause the GTR's are twin turbo so the turbo is suited to power 3 cylinders cut the godzilla engine in half (1.3 L engine) and you would be under sizein.... be better off wf the GT series turboes (gt25 or 28 etc)

SR20DET injectors are no good. get CA or FJ.

The RB226 from an R32 had a pair of T28 style turbo's on it with ceramic wheels. they are useless for your needs because the turbine housing has studs on it that bolt through the manifold. our manifolds have the studs on them that bolt through the turbo. no swapping.

I dont think its to hard to change some studs around is it

Ben why are older CA & FJ injectors ok, but not SR20 , surely newer design and age is better.

have a look at them. not all injectors are made the same. New S15 wheels look better than our stock wheels, but they dont fit either. i'm not sure why you think new technology has to be compatable with 24 year old stuff. times, change, cars get better, SR injectors are different.

these injectors will fit to

.ford tx3 bp 1.8 turbo injectors= dont know size but bigger then ours

.mazda familia gtx and GTR injectors= gts about the 370 and gtr about 550cc

.all 13b injectors but s5 and up are the best 550cc

.a certin volvo has 550cc injectors and they bolt straight in

this is a pretty clear case of people no searching. if you go to www.n12turbo.com, oh my god were there now... and look at the technical stuff.. you'll find this; http://www.n12turbo.com/mods/injectors.htm... what do you know.. someone has done the work for us.. many years ago... cheers to sash for the info.

on a less facetious note, the E15ET injectors are dark green in colour and the RB30E and E15E are light green.. dont use these.. they are smaller....

FJ20T 450cc
Supra (single turbo) 440cc
VR4 450cc
13B N/a 430cc
13B Turbo S5 550cc
Bosch 036 (Merc V8) 380cc 76HP
Bosch 024 (Volvo) 380cc 76HP (Not sure if these fit)
Bosch 402 (Ford??) 330cc (Not sure if these fit)
Z18 350
FJ20 350
CA18DET 320-340cc 60-64hp
RB30ET/E15ET injectors 250cc 48HP
RB30E injectors 200cc 40HP
CA and FJ are hose tail and bolt in
4AG(ZE?) fits

The SR series of injectors are not interchangeable with the E15ET engine and are only listed for flow rate values:

SR20VE 333cc
SR20DE 259cc
S13 SR20DET 370cc
S13 SR20DET injectors 380cc (Purple) 72hp
S13 SR20DET GTiR 444cc
S14 SR20DET 420ish? (definately bigger than S13; also series 2 bigger that series 1)
S14 SR20DET 480

Hahahahahaha all good except for the flow rates of the FJ20et injectors.

There are very often quoted at 440 to 450cc (which is wrong) but they are actually 375cc injectors! Pretty much the same as CA18det injectors.

There are precious few here who will go anywhere near maxing out a set of CA or FJ injectors!

yes someone needs to fix those flow rates, as been said time and time again.

hey even, i have fj20et injectors that i will be putting in, do you think i would max them out with 18-19psi with a GT28r and fuel system to support of course (standard reg). some say yes and some say no.

if your pushing about 180-200kw's at the wheels you'll hve those FJ's close to maxed... you should be able to get close on 140 with stock injectors and fuel reg.
