Hey all....ii am running a t-78 for some time now and looking to upgrade to perhaps a t-88 or even t-88h. Anyone using or have experience running the T-88H.....would love the gt42r as most do..but not looking to upgrade manifold, and exhaust

 

I had the 88H and hated it. Very laggy for the little power it produced.

 

get a T4 gt4276

i personally like the T88 but most of my experience with it is on Supra's. i can imagine it not being anywhere near as responsive as a garret counterpart.. probably the same price too!

 

How is the response time on a T4 flanged gt42r ? I would think a 1.01A/R would be better for a T4 flange......probably close to a T-78...but mich more power potential....?

 

Not that good and your opposite. The T6 frame will spool quicker on the rotary due to the larger runners.

 

Ahhh yes...well i am only running a street port so I am guessing no matter the flange the gt42r isnt going to be the best upgrade from my t-78

 

Wrong again! I made over 700rwhp on a street port. The GT42R comes with a dual ball bearing option which allows it to spool even faster. I reach 20psi by 4600 or so.

 

I can't agree with you more.

That was one boring turbo. That thing moved like a turtle with rigamortis

 

But, You're ErnieT................

Not many people have the ***** or money to do what you've done.

 

What flange and a/r where you running with the 42r?

 

Ernie is running the T6 1.01 A/R GT42R

 

T6 1.01

 

so running the T4 that comes with the t-78 probably isnt a good idea

 

Wouldn't fit anyway.

 

jesus you can make 20psi by 4kish, in what gear? you say streetported but how aggressive of a streetport is it?

 

it depends on what you want. i tried to drive through the canyons yesterday and lets just say i never hit boost haha. if you want to feel power without waiting too long get a smaller turbo or stay with you have
