Stock rb25 turbo on sr20det

Hey guys had a t3/t4 turbo on my car and its sucks big time do not like the lag, i had a T28r on my car before the t3/t4 and man i enjoyed that turbo spooled up really quik and fun to drive as my car is an every day car and with the t3 the turbo spools to late, i managed to get a good condition stock rb25 and noticed it a t28 with a t3 exhaust flange, i have a top mount manifold so it bolts right on but would like to know if the turbo will boost late? And what rpm would the turbo start boosting as its only going to run on 4 cylinders as aposed to 6 cylinders.

Any help would be appreciated

I was planning to use one on my CA, but broke the ceremic shaft in whiles strugling to get the turbine housing off(be very carefull). I believe it would have worked well on the CA so it should spool very quick on a SR and i would definately try it.

You will have no lag. Don't boost more then 0.9

Haha

hahaha 😂

on a more serious note, my rb25 with the std turbo felt like little to no lag, seems like from about 2250rpm and you were away mabe less
i want 1 for my CA, or Sr if that happens...
good cost effective upgrade for ca/sr i think, will have nice response

only downside as rat stated is no boosting over 0.9bar, ceramic turbine..

why did the put a ceramic turbine in?

lighter then steel for faster spooling

heard you don't need a cool down period either

Thanks for the replys guys heard if you go over 0,9 the ceramic turbine basicaly shits itself into pieces,so i was thinking ill go 0,7bar max on the turbo, any body know the thread pitch of the oil feed hole on the stock rb25 turbo?

I dont know so much about that one hey, i still think it needs cool down time to prevent the oil from cokeing inside the turbo after a heavy run, i would not chance it.

T3/T4 with .48 exh housing spools up faster. See dyno print on SR20. This was the same car, same turbo, just different exh housings. T3 .48 and T3 .63.

i run a garret t3/t4 with 0.48 housing on sr20det full boost 1 bar at 3000rpm

great response

i think you just got any t3t4 turbo without matching it correctly

thats a good looking torque curve

I ran the) turbo on my ca. I got the turbo from barry. A while back. I waas not happy with it at all. It felt laggy to me, compared to the stock turbo. But the dyno graph proved that it was not. But it just never felt right to me!!!!! It is hard to explain. Ran it for a full year on 1bar, the absolute upper limit of that turbo. Allot of guys say I am lucky that the thing did not decide to dissintegrate!!!!!!!

Turbo is on my car now and must say it goes awsome wheel spin from 1st,2nd,3rd gear no problem goes side ways with ease and its only on 0,5boost so im expecting good gain once i turn the boost up, must say the garret T28r spooled much much quiker then the RB turbo, not sure why the RB turbo did not work on your ca i think its a nice upgrade for the ca as its easy to get only thing you need to get is the exhaust manifold adaptor to accomodate the t3 exhaust turbo housing.
