I dont think that you can get that high without forced induction, and if you could the price to do it would far exceed even the most expensive swap several times over. As much as I would like to have that particular magic number for my own 5sfe, I dont think that its really going to be doable considering the alternatives...There are alot of people using the block from a 5s to get some great numbers but those motors, as far as I can tell, hardly resemble a 5s when everything is said and done...I think a more realistic number might be skirting around 200 without forced induction. You could get that number pretty easily with a 5sfte, (turbo 5sfe) but once again cost is something to consider. The most obvious thing to do is aggressive cams, but that is a 700 dollar bolt on...and without significant engine management, you are only going to get so far. I have thought of mating a 3s head with a 5s block, the prob here is alot of pricey machine work and being forced to get new pistons and such. Also there arent any things I have read about the successfulness or reliability of this particular combo. Someone else may have somethings different to say but I am basically regurgitating what I have either read here in response to my own questions or from other sources.

The 5sfte is pretty reasonable with some work, http://www.mr2.com/kb/index.php?article=10
That should give you an idea of what you are up against if the 5sfte is something you are willing to do.

Strengths and Weeknesses
Modifications

Check those out...

Also, doing some math here
Stock 5s, 135, plus cams, maybe 30ish, IHE, 20ish, thats 185 NA horsepower. (Generous HP #'s)
On the cheap end of things thats roughly 1000 dollars or 18 dollars a horse. Throw a piggy back in there for about 400 or so more and maybe a little port and polish here and there. Then you would have a pretty reliable tuned motor crankin out about 200 horses without significant engine work or having to tear anything out. (Other than cams) Total cost b/w 1500 and 2000 dollars (If you do most of the work yourself) Thats just me guessing however, someone else here may chime in with more accurate info

..i hear so many ideas about the possibilties of a turboing a 5sfe and making it more powerful than the 3sgte because its a 2.2L vs 2.0 ...but i have not seen any dyno numbers to prove that. i even looked at the camry with 5sfe and turbo kit...haven't seen any one get more than 200rwhp

I think Gen I turbos are the only ones similarly compared to...the gen III have somewhere close to 250...but either way, 200 is going to be significantly better than the 135...

.... the 5sfte record is 500RWHP and it ran a 10 second 1/4 mile.

300 is cake..

Ok Toms, I have heard rumors of those numbers but once again what did that cost? Nutty1 I dont know what you are planning on spending but I want those numbers as mush as the next cat with a 5s but reality comes into play too, Im sure a big turbo with enough engine management will get you there, but once you get that high axles and trannys come in to play as well. If there was somewhere around 50 horse to, I dont know, 1000 dollar ratio modding might become something to consider...I am looking at the local Pull-a-Part for sourcing old 5s blocks and cranks to eventually mate with a 3s head sourced prolly from here somewhere, Then using more aggresive cams and tuning to see what i can get out of an na motor...It depends on you, really sky is the limit if budget isnt a concern...

get a clip, 3500 bucks will get you about to what a stock 3sgte is. Go buy a gen3 clip, and enjoy yer 250 horse . Then when you get money, drump 3500 into that and have ~350-400 horse.

5S is through and through an economy motor, don't waste your time unless you have lots of money and just wanna break a record...

Tom knows what he's talking about you ingrates. He's not some asshat coming in here trying to feed you pipe dreams.

I guarantee you that Mike Colon spent at least as much on his 5sfte as he would have on a 3sgte. Big power is bigger money and the higher you go the more it's going to break. If budget is your primary concern for you then you have no business chasing it.

For 300 whp check out the power primer to see what it'll take to get there with a 3sgte or look at a v6 swap and mod. Money wise it's just not worth trying to get a 5sfe there.

Yup and he was actually the quickest MR2 in the US down the quarter mile for a while.

As Tom said, 300whp would be cake but not worth it IMO. If you want to go turbo do it with the engine and car that TOYOTA designed.

No rumors, it's all true. You guys are just too new around here to know who Mike Colon is and what he did with his car. He's now swapped to a 3sgte and is among the leaders in hp output.

That was in the days of Aaron Fowler, Jim Snodgrass, etc. The pioneers of the 5sfe performance. Too bad they have gone their ways. I haven't chatted with Aaron in a LOOONG time (2 years) but cool guy and new his stuff. He actually painted (by air brush) Mike Colons car and did a sick job too!

I'll see if I can dig up some info on it but I doubt I can link it cause it's from MR2 OC.

Well I'm having trouble finding my old links to his 5sfte days and his drag runs with it but I did find MRturrari's link below.

A good link for you 5sfe guys. Turbocharging a 5S-FE

mike colon ditched his 500whp 5sfte for a ~550 (? around there)whp gen3 3sgte. when asked what it takes to build a 500whp 5sfe, he said the same thing it takes to build any other 500whp 2L 4cyl. he was also on the stock valves

when you're making power like that you replace everything, including fuel systems and management.

another 5sfte guy, "manny" is making almost 300 ft/lbs on a bone stock engine, with stock cams! its not a question of weather the engine will make that kind of power, because it can, has, and will continue to. all of the fastest mr2's in the united states have used 5s parts, either the block or crank or both.

for 300hp, going 3sgte saves you from having to swap cams.. but even on the 3sgte 300whp means a new fuel system and many opt for new management too, and still many opt for forged rebuilds. the point is making power is expensive regardless of what you start with, some engines are just marginally easier.
