SR20 T28 and 550cc injectors....

[datsunboy]

how much power could I expect from upgrading to a SR20 T28 turbo running ~14psi with 550cc injectors, Z32 MAF and a 2 1/2" exhaust. with a dyno tune?on a otherwise standard CA18DET?and how much extra would I gain from then geting a 3" exhaust? ( I don't have any exhaust yet, so deciding if it's worth/needed to go to 3" )

also, what cars can I get the 550cc injectors from?....I've heard they are from 13B turbo's?

any help appreciated

[getnrowdy23]

max horsepower out of a big28 turbo is around 325. so i would say around 250 or so...tuned

The most I've seen from an SR20 T28 is about 330 on the SR and about 310 on a CA.

Flywheel figures.

CuzanO just pulled 277whp out of that setup but with 3" exhaust.

(he got 277 not 222 Ryan;)) -Sean

(He got 222 @ 14psi which is what he asked, you silly rabbit) - Ryan

do you think it'd be possible to get a reliable 200 HP at the wheels with that setup and a 2 1/2" exhaust?....or have to go with 3"?

[Jezz_s13]

yeah easily possible, I know of a car with a reliable 390ish @ wheels with a 2.5" exhaust.

The T28 will be fine for 200RWBHP too.

do we want high or low impedance injectors?just saw some for sale

[biosehnsucht]

CA18DET normally uses low impedence injectors

[datsunboy]

normally?as in I could use high impedance if I wanted?.....what would you have to do that?

[Jezz_s13]

I believe it can be bodged to use high impedance, not sure on the technicalities though.

If you use after market management then you can use either I guess, but the stock ECU setup uses low.
