Garrett 3076 on a ST185 celica GT4 ?

[st185-gt4]

hi,

just wondering whats everyones thoughts on what mod im missing with my st185 celica gt4. I have just taken my car from a dyno tune and before tune i got about 143kw on the dyno. after having my EMS stinger ECU installed with a tune i got 166kw at the wheels so in all i got about 23kw gain just from installing the ECU with a tune and graph also shows i doubled the car's power on low end. Is this descent in ST185 GT4 standards ?

My goal has always been to have it at least close to 200kw and the tuner has told me the stock CT26 is what's limiting me as the wastegate fluctuates too much on high rpm's therefore the boost dies down a lot during the high gears and advised me to get a better turbo .. something like a garrett 3076 since the housing and the design is ideal for my car and wont fluctuate too much like the ct26. He said once i have that installed along with maybe bigger injectors i should easily be able to reach the 200kw mark that im after. Would putting a bigger turbo like the 3076 etc still be safe to run for this car or would 200kw be pushing it and be a bit too much for this gen 2 st185 engine ? any other ideas on what turbo would be a good investment for the car ?

At this stage my car is stock apart from having a 3 inch full exhaust with the downpipe, 255cc Walbro fuel pump, Blitz electronic boost controller (currently running 16psi), Front mount I/C, and just recently now have a EMS stinger ecu.

Any thoughts is appreciated. Thanks =] .

My thoughts are sort out your licence issues first ..

A CT20b off a 205 pushes enough to make 200kw atw.

A 3076 with a .64 rear housing would make it reasonably punchy and still push 250-280 awkw on the right engine.
I advise getting bigger injectors though as stock gen2 ones would max out at about 180kw.

If your goal is 200kw get the smallest turbo that will reach that goal at the desired boost level.

indeed, a ct20b (which is a direct bolt on) will give you that power on the right engine. Or a Garrett GT2860 if you want something with bit better response and a bit more top end (at the expense of greater cost and modification to fit).
