Hay guys im getting ready to replace my stock GT25 with the GT28RS, i have never changed a turbo before, this is my first turbo car. But i know its just a swap so i will not be hard at all. But i was wondering what i will need if anything. Like Gaskets, new studs, or anything else you guys can think of im also putting in a new fuel pump so anything i will need to do that let me know as well

Thanks,
Fatti03MSP

do you have forged rods and pistons?

You will need new studs to replace all the old studs...they will probably snap off at the head(so you will also need the tools to get the broken stud out of the hole)

no i dont have the forged rods and pistons yet, so im going to stick to 9psi and can you get the studs from an auto store or do you have to get them from SU.

9psi is pretty high for the gt28rs without fuel management.

they might be hard to find. I would pm Bagman1 and see what they cost (or start a thread in his section of the forum)

Im not too sure about this, but i think the bigger turbo might bring the breaking point for the engine down...meaning that 9psi on the gt28 is stronger than 9 psi on the t25...so you might want to be careful with that or talk to some of the members who have done the swap.

i believe you have to clock the GT28RS so that it is oriented in the right position. do some searches on here, there are some members running with the disco potato.

I am at 12psi on my very slightly smaller IHI VF22 turbo with a J&S Safeguard and Haltech. Just lookin out for ya! Definately needs to be re-tuned after install.

But what do you mean clock the turbo, this is all new to me.

well he is graduating pretty soon so I will probably only be making one more trip out there in the near future, but when I do I'll definately try to let you know so we can check out each others MSPs. Mine will have some forged parts in it and a Meth/water injection kit by that time!

post 15. thats what i did. (this post refers to using the RS can)

the stock bracket doesnt just bolt on it has to be modified. dont forget the rs can is 10psi so u cant go lower.

What is the break in process to a new turbo?? this is my first new turbo.

Dude, you are going to need all the associated gaskets and seals, a different intake (or modify yours, it needs to be 3" in order to mate with the turbo inlet), you'll need to fabricate a small bracket to make the WGA work, you will need slim cooling fans (GT28rs won't fit with the factory fans), you'll probaly need bigger or extra injector(s) and it will definitely need to be tuned. After all of that, you may end up needing a new engine after running it for awhile. Your stock internals are weak. This is not really just a "pop & swap" project. Please do a lot of research before attempting this!

no break in technically. u can run oil through it before u put it on the car so its prelubed. but thats about it really.

Ok thx

"Lol" OK...

This is what the msp is working with rod/piston wise. I've seen them let go at less than 10psi from the stock turbo, however that is not always the case. Good luck to you.

thx man, thats y keeping the boost at like 5 for daily driving and 9 for when i go to the track.

i didnt prime mine and it worked fine. but we have oil in our lines anyhow, i agree on a new turbo setup though. im not disagreeing with it needing to be done, just a fYI
