i have a redtop sr20, i blew my T25, so i'm now upgrading to T28 on a budget, only have 1,100 to spend... what do i absoulutly needs for the s15 t28 swap?
i plan on getting an aftermarket elbow, and piping adapter kit. but are oil lines needed? or can i use the stock hardlines? someone please help!

i believe you need an oil restricter (sp) as well. because the t25 is journal bearing and t28 bb or it will ruin the seals. I dont really know though. Also s15 t28 will max out injectors so new ones will be need unless run really low boost and if you get injectors you will need safc or new rom tune.

eh, dont worry about your injectors and such, just run stock boost you'll be fine. while you're changing everythign out you might as well change to ss turbo lines (get banjo style oil line). dont really need a new oil return tube; just notch the flange so it fits on the s15 turbo and you're good to go. that should keep you under your budget.

nothing really just need to fab the hotpipe and hotpipe putlet aswell youll have to bend some line for the oil unless u get the steal braided lines which would make it alot easier on yourself other then that it just about staright bolt on,and might want to upgrade your fuel managment asap unless u wanna run under 9-10 psi all the time .ive got the gt28r too and i love it,just remember NO FUEL MANAGMENT NO HIGHER BOOST good luck

so i can run 10 psi on T28 on stock injectors? and how will that compare to 14psi on T25? will T28 at 10psi be alot faster?

kensreliableb18b · 10-06-2006, 10:56 AM

dont run 10psi, just run off the actuator. you should feel a difference between the two.

10psi on the t28 is pushing it with stock injectors. I just installed my t28 on my redtop. There are a few ways of doing it.

MAKE SURE you get a s15 oil return line/hose. It makes things so much easier. I used an aftermarket oil line, aftermarket coolant line, and stock coolant hard line from the t25. The hard line im talking about is the one going to the back of the engine. It will need to be bent a bit inward to connect, be careful when you do this.

Putting in the turbo is a BITCH. Its a very tight fit.
