t28 turbo is best suited.. full boost by 3700rpm hold 16psi to redline.. Imo t2 flange the way to go.. Weld shut the internal gate and run external
hey Guys,
Been doing a bit of research and trying to work out what turbo is best for a 4agte setup. Running a stock gze ecu with (front mount and exhaust). Currently have a t-03 or what i thought was, but all i know is it was off a series 5 rx7 seems laggy. Looking for a fairly responsive type setup good for little bit of slidding but mainly just street and some good fun.
Whats been done/run and works well or what do you boys reccomend?
cheers

t28 non ball bearing of aussie s15 and all s14s. so much more responsive than a t28bb version and yeas i hvae done a straight swap comparison on my car!!!
AE86 THE BEST
whats the lag difference between a t28 and t25g?
They feel both the same.. But the t28 comes on harder.. t28bb turbo is faster spooling but you dont feel the torque as much as when a bush t28 comes on so its hides from you.. I would recommend a gt28rs for big power stock block. But for fun response gt28r from s14 , s15 bush bearing
what about the kkr280 and 330? they would be easy to set-up.
easy to setup? y any easier than any other turbo???

Go T28 roller bearing
you won't look back mate!
because they dont need water lines ran to them.
how much power could i expect out of a smallport with a t25g or t28 on it?
Nic19, I've owned a KKR330 before and it had water cooling. It's marketed as a direct replacement for the T25, and thus uses the same lines.
HKS GT2510 is apparently a brilliant turbo for the 4A. It has almost identical sized turbine and compressor profiles as the T28 Ball Bearing, but obviously with improved fin design, etc for faster spooling and a little more top end power. If you want a cheaper option, but something brand new, the Garrett GT2560R is the "aftermarket" version of the T28BB. Can be had for around $1000.
If you want something that gives out more power but at the cost of having to rev higher, maybe a Disco Potato might be the go? Would also be suitable if you have cams + headwork.
EDIT: Ball bearing is a nice feature, but not necessary IMHO. Internal wastegates are a blessing too. I didn't do them on my build, but I kind of wish I had in retrospect. Very similar performance for less dosh.

Where will it stop? Will it ever be finished? How will it go? Why am I not wearing any pants?
