looking to help a friend setup a new turbo job on a 98 GSR

starting from scratch no internals, etc...

just dont know where to start-
thinking of gt28 series, t3/t4 50 trim with a .48 AR, but just cant decide
any suggestions appreciated

also- what internally gated turbos do you suggest

 

gt28rs...for future upgrades

 

Why spend 1300 bucks on a GT28RS when you can spend 600 on a T3/TO4E 50 trim and be done with it.

i agree- the ball bearing isnt gonna make that much of a diff.

 

GT32e. . . .

b18flip had one on his stock motor'ed gsr, made 290whp. . .

spooled full boost by 3800k he said. . .can't ask for more than that

 

imo...i like bb turbo chargers and on top of that.....the gt28rs is a great turbo...you can find one for pretty cheap if you actually look

 

250whp? Get a GReddy kit.

Don't waste your money running a SC61, GT28RS GT30R or the like at 5 psi to impress H-T.

 

its all about what people want man, not something to impress others

 

i had the greddy kit on my car- it was tough trying to hold steady and constant boost without spick/creep or better yet- drop off- i think it has to do with WG placement as well as size, i think the gate is placed too close to the inlet

as well the dp is small, and can be the reason for the gate opening earlier

 

I was at the Dyno the other day and they were tuning a 96 totally stock gsr(even intake manifold) hella homemade turbo kit, with a super 60 turbo (******* hairdryer turbo super small) they made 235whp. Also getting extra grounds on your engine could gain some horsepower, my friend got a grounding kit and gained 11.1 whp.

Exactly, if your goal is only 250whp, than go for the g-reddy dogg!! Seriously though, I have used a couple of those kits (along with many others) with great results...Even if you wanted more hp later on, you can still use that turbo for about 300whp or a little more....Great street turbo!!

What boost level were you running????

 

TRYING to run 10, 12, even 15 psi but boost keeps falling off to 8psi and held steady.

I upgraded everything on the kit, downpipe, wastegate, exhaust, bored the wastegate housing, etc.

nothing worked.

 

any more ideas?
i thought of an sc34 but thats overkill too
something smaller.... anyone?

 

I would also go with the gt28rs, as your powerband will be huge with virtually no lag.

 

you can also try a t3/t4B turbo, smaller than the E housing cheaper than the GT28RS

I left my kit all stock as it comes from greddy, and never really had any problems...I just had to make sure my wastegate vacc line was real short, and also had my manual boost controller set properly..(turbo xs dual adjustment)..

My buddy has this on his stock ls motor..It spools up fairly quick..

 

t3t4b will spool up quick but will lack topend, just go with the E housing, you won't regret it
