Tomei isn't as fast spooler as you might expect, but 120kpa beyond 5k sounds kind of slow! Check if you have any boost leaks. Also, EVC6 is an excellent EBC but it could be tricky to set, I suggest that you carefully read the manual & make sure that you have all the right settings.
120kpa is kinda of low for such turbo, I suggest that you tune your car with 1.7-1.8 boost in mind.

 

No problem, I've tuned a GT-A last year, E5 turbo, BC264 cams, 25psi, 98ron + meth injection, a very nice car with the auto tranny, high end power was very satisfying.
Let me know if you need any help when tuning the car, as I mentioned GTA ECU rom is different than other roms, but Australian tuners have excellent reputation... so you should be fine.

 

Yeah im sticking to 98 theres basicly no e85 sold around my area yet to much of a pain to keep filling up!. Sounds good on the head studs there not to dear but rather save the money if possible lol

 

Very interesting topic. Current my evo 7 gta.
8mr turbo 1.4bar with ECUtek tuned.
Walbro fuel pump.
Aftermarket intake, exhaust and extractor.
others are stock.
Only got 260whp on dynojet. Btw my country only have ron97.

Someone offer me hks gt2 7460r ballbearing turbo..

Thats not bad for the mods!. Im running the same mods as you but the turbo will be a DBB FP Green. If I make 260whp ill be happy that was my goal to start anything over is a bonus .

 

GTII is such a fast spooler, in my opinion, it would be ideal for the GTA, but it could be tricky to tune with MAF.

 

Dyno of said GT-A you had tuned??
It is almost mission impossible to find EVO GT-A dynograph online

 

Arghhh ><. Tuners called me today. Reason I put the car in was mainly cause my radiator was leaking coolant from the top so was getting an aftermarket one + figured to save on labour costs ill do the turbo at the same time. They just found rust all through the turbo and other parts and tell me its a blown head gasket that could be caused from the radiator or just cause the cars 11+ years old now. Not the thing I wanted to hear ><. So now I have to replace the head gasket at the minimum depending on if it caused other damage, so im getting the head studs done as well since they have to take it apart . So results will be a little delayed!

 

if u want see simple mod n tuned like my evo7 gta dyno graph.. my cars got few paper with few spec and boost..

i can scan to post here if u guys wanna to see.. But don't laugh XD

 

Scan it up and post
260whp EVO VII GT-A is not bad considering stock EVO VII GT-A will dyno lower than 200whp on dynojet
Have stock figure also?

 

First dyno graphc spec is
stock evo 7gta turbo
aftermarket extractor and intake
greddy profec b 2
Apexi safc
Engine is fully stock, included intercooler. Just some samco hose.
(When i just bought this used car , previous owner didn't tune. He just adjust hi/low boost himself and proper AF tuned)

Very nice. So the 8MR turbo actually hits full boost quicker then the stock?

 

yes.. the power at earlier rpm range is a lot better.
dun forget ori gta turbo is 9.0T.. my 8mr is 10.5.
I guess material turbo is different. I tried weight the GTA turbo feel bit heavier than 8mr titanium turbo. 8mr seems lighter.

Actually can get around 270-280.. tuner told me my gearbox has something wrong.. he didn't check and already tuned.
Now shd be higher than 261 since i rebuilt gearbox last few week, now feel more torque and top end power..
Again somebody offer me his HKS gt2 ballbearing turbo.. Now i'm planning upgrade again since my gearbox rebuilt to withstand more little torque.
I asked my tuner he told his client same E7 gta similar mod with gt2 7460r, stock cam, can get into 330 no lag.. strongly suggest ballbearing.

Side effect is my oil temp raise 10 degree after changed into this. Performance is worth it.
I sold my 7 GTA turbo to airtrek user.. they love it.

 

Ah nice thats promissing! hope my tuner can get similar results Im going with the DBB FP Green so should be fun .

 

I've viewed GTA rom recently, very interesting kind of piece, different fuel/ignition maps in different gears, tables for auto tranny operation, miliseconds adjustment how fast to upshift or downshift, at what speed, at what tps etc.

should be fun to tune it, foxbat should know this
