Ya i looked that up as well...but $2500 for that thing? Little much....rather not do it at all in that case. I could buy a good supercharger kit after all that.

thanks for the input i will check around

Sorry there have been no pics i still have not gotton the car back from evo sport in cali, i am now getting the clutch upgraded, and i am thinknig i should just get the bottom end upgraded and turn up the boost!
This is not a lie nor a joke i am not that bored in life that i would come on here to try and lie to a bunch of people i do not even know! There will be pics, and for people in mn you can come check out the car when i get it back. Or if you really do not believe me call EVOSport

I m in minnesota and would love to see it when you get it. Hit me up, **** we should even run.

At the very least, I would port .5" into the port to port-match to manifold, which is probably m50 based (m50,m50tu,s50,m52,s52)... of which the basic castings are all the same. I would port as much as 1" into the exhaust port to try and achieve the smoothest port-match.

As far as turbo, to really use it with a m52tub25, it needs to be built. Otherwise I feel it's tremendously oversized. You should experience 0 dropoff at upper rpms, but with the boost levels, displacement and compression ratio you have, it seems to me that a gt28 would be far more appropriate blower that would yield similar numbers with a far earlier spool. With the TT t3/t4, at 8 psi I made over 300whp on a very conservative dyno. Granted your motor is smaller, but I think you will manage better curves, much more area under them with something smaller.

I'd have to agree here. If your not planning for anything greater than 3 a 57trim/ gt28rs would have been perfect. In terms of driveabilty. Even a gt3076r divided would have made good power in the 500's. W/ a quicker spool than your gt35. All in all I'm sure you'll enjoy. Jumping straight to a 35 means somebody may just have big plans

Big plans is correct! Now well see how long it take to fully build the motor after i have saved up enough!!!!!!!!! LOL! Ya Sheefo thta would be cool i will for sure im you on here when it is ready! Peace JHN

sorry they are not going to be 323 rods

6 months and STILL no pics???

So if you're getting the bottom end built, does that mean more boost? If you have an auto, will you re-built the trans?

We'll need some pics soon.... (or im going to call EvoSport like you suggested)

Seriously though, do you REALLY think 650+ WHP is something youre going to be doing? i would FOR SURE sell that monster and go with an HTA 30R. They spool so very quickly (and make close to 35R power). i had one on a 1.8 liter motor and it was great!!

This turbo is WAAAAYYYYY TOOOOOOOOOO big.

89.6mm crank + 140mm rods do not traditionally work together

I'd have to agree with this...the 35r will be nowhere near its full efficiency range even when running 12-14psi as those turbos live for 24-30.

I had one on my Eclipse (2.0l) and made 450whp on low boost (22psi) and it was well over 500 on high boost, but if your not looking for those numbers grab a smaller turbo so it can spool faster. Either way sweet build and I look forward to seeing some pics.

Sure they can!

You just design a piston with the wristpin sitting above the ring package.

i better return those parts then. what do you think i should get instead

I think enough people read my rant....

If you are going to buy an 89.6mm stroke crank, it's likely to be connected to a set of OEM 135mm rods to start with. I'd use that crank, OEM rods, and some lower compression pistons. That will take you easily above 400rwhp.

The cost of those parts is going to be dwarfed by labor, machine work, and supplies to pull your engine, rebuild it, and re-install it.

that's by no means traditional. But yes, it can be made to work and is better as it'll result in lower piston speed. Bav solutions does one of these, puts the oil ring on the wrist pin.
