300hp on a 5sfe 2.2??

Also How much PSI can the 2.2 take? What kind of HP am I looking at with my set up so far when a Turbo is Added. I have a .57 trim Laying around if that helps thanks.

You're essentially building a 2.2 stroker, which involves a 2.2 5SFE block, a retro-fitted 3SGTE head onto the block, a turbo, wiring harness, ecu, and exhaust system (bare in mind I was giving a broad list here) but essentially that is what you are building.

2.2 strokers are generally built for extremely high BHP because the 5SFE block is stronger the 3SGTE block so it is normally chosen for that application. However as far as what kind of BHP you can expect from it, that still all depends on what parts you use, the tuning, etc. If you gave a complete list of parts then maybe you could get a rough estimate, however if you plan to run just a
5SFE block
3SGTE head (running stock internals or close to stock internals)
turbo pushing 14 pounds of boost,
a cat back exhaust,
you'll probably be in the area of 230BHP, I don't think you will push anything more than 245BHP which is the same as a 4th gen 3SGTE.

Again these are rough estimates, unless you plan on completely rebuilding and upgrading everything right down to the very last bolt and washer, and plan on getting some seriously monstrous BHP gains, of around 600 BHP or so, it might be cheaper if you just dropped a 3rd or 4th gen 3SGTE in there and started with that.

The 3SGTE block is by no means crappy or weak. Plenty of people get monstrous BHP out of the engine and the block will take it, but its just when you start talking about unbelievable amounts of BHP that some prefer to build a 2.2 stroker for extra longevity.

The highest HP Mr2 ever recorded was on a 3SGTE block. Until someone breaks that mark I don't believe that whole "like zomg the 5s block is mad tit3 stronger"


p.s. A year later this thread is still full of fail and lol

Hmmm this thread is full of fail and lulz but I have driven a 300whp n/a 3sge (not 5sfe). It was a speedway midget and had no clutch and direct drive to the rear wheels on straight cut gears to minimize power loss. The car ran methanol injection with 14.5-1 pistons and some trick rods to suit the tricked out pistons. Knife edge crank (stock shaved) and the gen 2 3sge head that had been worked to hell but I don't know exactly what they did, I could see adjustable cam gears though (idled at 3k minimum and was just coughing the whole time under 5k). Revved to about 10k and if it was not exactly 300whp it was very close in the high 200's.

It was insane and accelerated faster than anything I've ever driven but had no torque and you had to be bouncing off rev limiter constantly to keep the power up. Also the injectors caked up and had to be soaked in petrol overnight after each race meet. Totally useless for a road car or most forms of racing but it was awesome all the same. I had to wear double layer fire gear and all the dressings before I was allowed into it as well. Oh yeah and for the money sunk into it a turbo and a stand alone setup would perform better in a real life situation.

hhhmmmmm Well I'm Excited and Scared at the Same time About my Set up. It needs work on the outside But I might just drop it all in the motor. Is there any point in getting cams tho? Like how much will I ain from just cams? If I go all motor
