The pre-set on the Wastegate is 14.7 psi.. Is it possible to just throw this turbo on and leave the boost at 14.7 and not worry about running lean? Or do you have to do big in jectors if you keep the boost at 14.7 psi

eventhough its the same pressure, its not the same volume of air. its not advisable to put on a larger turbo with stock injectors and think you cannot run lean.

Mark, you should also consider getting a external oil cooler for the warmer months when you will be on the track. Its as important to keep the oil cool as water to help prevent thermal breakdown of the oil at high temperatures.
Cant wait to see your results

Cobb heatshield had to be bended out a bit. but I seriously won't even call that a "fitting issue". It fits Process West TMIC just fine but I can see it could be a potential problem with something bigger TMIC

M8265 uses a slightly larger inlet, though not 3". an aftermarket silicone inlet will slip over it.

i only had to trim my oem heatshield a bit to clear the wastegate arm. otherwise everything fitted up just fine.

I always forget mods so I'ii update as I remember.

I have been driving with the above mods for a week now and can say I really enjoy the different between the vf39. I dont have any numbers, but I can say that boost builds much faster and I'm at full spool at 4200. On dry days the tires start to break loose into second gear (Rs-2). In my opinion, part throttle passing on the highway is the best. If Im doing 70 or 80 and give it a little more gas I'm in triple digits. In addition the turbo is a little louder which is nice. I hope to get a bigger intake so I'm not almost maxing out MAF and then hit the dyno. My butt dyno gives this turbo a thumbs up.

A quick thanks to Sammy and all the guys at Six Star Motorsports and Ryan for doing the tune.

nothing earth shattering. conservative tune by paul at yimi - 325whp/317tq

seems its basically a TD06-20G. the power comes on very linear, it doesn't have that huge torque rush that the stock VF39 does at very low rpms. Above 4.5k rpms its very strong, the HP curve doesn't drop off at all, all the way to redline. I wanted an autox/trackday setup, and this does the job. basically i have to get used to driving it again since the power comes on so smoothly, and my powerband moved up quite a bit in the rpm range.

overall im happy with it, just know that there are other choices for 325whp.

Mark,

What boost level was this power made? And this was also on CA 91 octane correct?

That's a really flat HP curve from peak to redline. Looks like it can make alot more power with a more aggressive (non-track) tune.

paul had it up to 333whp and backed off. my car seems to be on the low/average side of STi's. it made 277whp/320tq at stage2.

the difference in power is definitely there, but the power curve feels like a built MR2 that i used to have. very linear. the engine now loves to rev up top.

i haven't seen anyone dyno the M8265 yet, but maybe it will be laggier, and give better numbers up top? for me the power curve of the M7960 is about as laggy as i'd like for my intended use of the car.

really.. i wonder what kind of power output the M8265 will have, but you are right, i think a synergy 20g for the price would be a better option. The curve looks great thou for your purpose! and you do got a tomei turbo at the end of the day...

I would assume the build quality and reliability will be much better for the other turbo options that would get that same power output
