Looking to possibley use this engine in a project, and since i don't know much about this engine i thought i would ask some of my friends here in TR.

I don't want to spend a fortune. I don't know how expensive a full package would run on something like this. And i don't know if someone here locally has experience tunning these engines. Is 300+ whp to lofty an expectation to have for a purely stock 3g from any of the 3 generations of engines? What kind of ball park am i looking at for getting everything i need to have a running breathing 3g with a drivetrain that can reliably put down the numbers? Is there a better alternative than the 3g for a 300+ whp fwd setup?

Those questions should do for now. If you must flame me for asking, at least include some useful info pertaining to the questions asked somewhere in your post. Thanks

 

its 3sgte

you can get close to 300hp if you get a 3rd gen 3sgte and put a good stand alone on it. all you need for more after that is to upgrade the stock turbo and bigger injectors. its a great engine and very reliable. as for tuning, the guys at XAT know the 3s very good i wold give them a call.

 

It seems like for the 2nd gen 3SGTE 300 hp is about the limit on the stock turbo. I believe that's a CT26 turbo (or CT20B).

 

Oops good looking out on the typo, sorry.

Is it a mandatory thing to go stand alone when trying to push the engin over 300whp, or is it just better/cheaper/less headache proned/more reliable option? Also, the injectors that come on this engine are what cc? How much hp will they support before going over the 80% duty cycle?

 

Do you want 300bhp or whp? What are you putting this project into? If you get the 3ed gen 3s you can achieve 300bhp with the stock turbo. I would think you would need a pretty good standalone and some tunning to achieve that at the wheels. Good luck. If you got anymore questions check out Celicatech.com. Theres a guy on a 2nd gen with 300+ hp, but thats with a t304 turbo on it.

 

its not a neccesity, but the stock ecu's suck ass and its alot more reliable to just spend some money and go stand alone. and a 3rd gen 3sgte with stand alone would get pretty damn close to 300whp. that would be my choice even over a SR.

 

I agree with bill

Megasquirt + 3rd gen + boltons = fast.

MR2 driver is going to say he's got 277 and close to 11's with a stock ecu.. but still. with the cheap cost of megasquirt II (has ignition) and tuning, standalone and reliability and cheap is finally a possibility.

 

Ok, so i'm at 300whp with a 3rd gen and stand alone. Before fab work and installation where does that put me money wise?

Do all these engines use a return fuel system? And how much whp will the stock injectors support without being over worked? Also, considering the 3sgte and the sr were to be matted with fwd trannies which one would be lighter, or are they so close that would be a none issue?

 

you don't have to go stand alone for 300rwhp but its highly suggested. the stock ecu has some aggressive timing maps, and typically does something funny when that volume of air gets registered. stand alone will provide you with reliabilty as well as the power you want.

 

the gen 3 has 550's. so it will hold what your asking of it. Riddle mr2 runs a stock fuel system about to its limit at 310-330ish whp. He could use a stand alone and a fuel pump and then go for upper 300's on stock injectors.
