more 5sfe ?

[camryfreak09]

why is the motor weak for its size 2.2l with a mid compression ratio. the only thing that i kinda like about it is its torque compared to hondas. i was thinking about chiping the ecu cuz i think theres alot of hidden power, but i could be wrong

[Rdizzle]

cause the head sucks major ass
It like toyota wanted to kill any potential for power or fuel economy and just half assed both

[camryfreak09]

you can switch the head with the 3s right?

[camryfreak09]

how about a port and polish

[Rdizzle]

the 3s swap is possible, do a search for threads about it.

The port and polish will help, but you would really have to change the cams to really take advantage of it.
In total the 5s is hard to producepower on unless you turbo it. Or you have alot of money to spend making a custom NA setup. I have heard with the right parts the 5s could potentially make almost 190 crank hp. But you are looking at alot of money. I think 150 is the highest horsepower i have heard of.

Everytime I see one of these threads I wonder what everyone is comparing the 5SFE against, remember this is an early 90's design. I have driven a number of cars with similar size 4 cylinder engines from that era and can't think of any that out preformed the 5SFE (at least not by much), some were in lighter cars therefore felt faster. When it comes to fuel economy I again can't see where anyone has anything to complain about, last month I picked my son up at the airport in Houston, TX ( 300 miles round trip, mostly 70 mph speed limit) in his '96 Automatic 5SFE Camry , it averaged 31 MPG, not bad at all for an 11 year old car given the 2.4 L 2007 Camry is only rated at 33 mpg.

The primary problem areas with the 5S-FE for producing power are:

1) Very very mild cams
2) Poor intake manifolds (designed for torque)
3) Valve angle

Also, the compression of the 5S-FE isn't really that high for an NA motor. It's only 9.5-1, a lot of cars run 10-1 or above from the factory.

You can argue that's nice, because 9.5-1 isn't too bad if you want to boost, and it's also not too low for NA builds. You can safely mill a 5S-FE down to 10-1CR.

follow CrawlingEye's instructions if you want to build a 5SFE for more power, or if you want to build it for boost ... read the 5S-FTE sticky at the top of the gen 3/4 forums ... i also have acquired a bunch of information on parts needed for a boosted 5SFE

im sorr i have to diagree about "the camrys max potential is 190Hp at the crank". A stock 95 camry with the 5SFE has 140HP my damn Weapon R Secret Weapon Intake gave me about 20hp, my custom race exhaust including larger downpipe, tubing, header, and canister muffler has given me an impressive 52HP and heres one more for you guys my Jet Chips ECU override and VFORCE PCM has given me an additional 40HP together. Mind you the compression ratio given was accurate and he is right about those damned cams (God I hate my cams) but Im over 250 Hp total & I just gave you about half of the stuff that I have done to my car. My car is not turbocharged nor supercharged nor on NO2, and I plan to swap the top end out with a 3SGTE and throw on some crower mild cams and valves. A 5SFE motor alone if built right can make upwards of 400HP (mind you thats a crap load of custom tuning and work and I hope you have the wallet for it) but it is entirely possible, I have seen it done. My car was tested on a DynoJet in Tampa Bay Florida using 93 Octane Fuel and Lucas Ocatne Booster, nad I was last at 256 HP before I installed my Header & Downpipe.

[Venom_5]

youre kidding right?

my Weapon R intake doesnt raise my hp at the crank at all

[Spartan0536]

no im not, i have found out that if you have a camry from south africa or egypt or some other place the engines are made differently even though it may be the same engine type. If this was the case as spoken about above I apologise, I had no idea that the designs are changed so drastically in other countries. But to answer yuor question Venom5 I noticed a huge difference in my cars performance with my *Weapon-R Intake.

*Weapon-R Intake used is the "Secret Weapon" Design with thier foam filter and a custom ram air adaption built by myself.

[CrawlingEye]

Spartan, a stock 5S-FE puts out around 100hp to the wheels. You're likely gaining minimal hp (possibly even losing some) with your intake. The stock intake is a psuedo-CAI , swapping an ABS CAI that inlets from a less than ideal spot to a shorter intake that sucks up purely hot air, will not gain much (if any) hp. Although you may have gained some lost hp from having an actually clean filter.

Furthering this on, your jet chip did not gain you much hp at all.

If you're going to make such ridiculous claims, I'd like to see some dyno's, because right now, I have a flux capacitor to sell you that will give you 100hp and it comes with a sticker that'll add another 150.


If you're getting crank numbers from a wheel dyno, I'd advise not taking your car back to that shop. Shops give happy numbers from tests they conduct like that with no (or little) accuracy.

I will state though that there's no 112hp from bolt-ons with a Camry. There's many with cams and much more work done that haven't gotten near those gains. I advise you to look into Jim Snodgrass's MR2 build for some actual information about a built 5S-FE than using your butt-dyno.

[Venom_5]

flux capacitors always do the trick!

like Crawling said, 120hp is the factory rating ... 12 years down the road im probably getting 100-110 to the wheels

[Spartan0536]

I will go do another dyno, hell even my Haynes manual and the Offical Toyota Repair Manual for a 92-96 camry states that it comes with 140HP. My Hp is not at the Wheels (I wish it was). I have seen many MR2's with 5SFE engines that are pulling near 280HP with bolt ons and no turbo, I have seen thier dyno charts, hell they used to go to the same car meets as I did. Im not trying to B/S anybody.

125hp / 145 ft-lbs for the 5S-FE stock .... i believe the 1992 had 130hp, but never 140 at the crank
