Ok my 5sfe is currently at 17 psi of boost with the burien kit. i been having it for bout 2 years and now the cluctch is slipping in third gear. Any one have any suggestion of what type of clutch is good? n also flywheels while im at it.

is that a typo? did you mean 7 PSI?

anyway. I have a fidanza lightweight flywheel and I love it. it made a big difference! as for clutch, I've got a spec stage 2 and haven't had any problems, but other people on here say they have. ACT makes good clutches.

ACT clutches are faultless. I've had them in all my Celicas and not one problem so far. I've heard mixed results with the other brands. I'd go ACT to be sure about it.
He must mean 7PSI. 17PSI for two years = Destroyed 5S I would think.

unless he got all the internals forged!!!

the proper term is "forgies"

I know to my suprise and to your suprise but my car been running 12 for two years and 17 the past three months with the Burien set up... It's not a typo!!!

and oh yeah... still stock internals unless the old couple before me change it to forged pistons...

off topic: wow what hood scoop is that?

have you added anything to the burien set-up. i.e. an intercooler or water/methanol injection? also, do you know what kind of power you are putting down and/or 1/4 mile times?

Nope... I added a front mount intercooler, same 360cc injectors and a 3 inch custom exhaust... Im hoping to get it to the dyno this season but the last time i was at the track i ran a 15 flat at 7 psi cause of a big boost leak... remember Im at very high elevation (New mexico)... probably low 14 at lower elevation... Im goin to take it to the drag once i get my clutch in...

Looks 5gen Alltrac.

Strong clutch, LW flywheel, LW wheels.

well, that just makes me think that possibly the 5sfe is capable of more than we ever thought... one day I plan on building a super 5sfte with all forged internals, big cams, big turbo, and lots and lots of boost right now I'm trying to build a very modest 5sfte set-up using a stock ct-26 from an mr2 turbo.

17 psi on the burien kit seems kinda high. It just seems pretty unlikely that you could run 17psi on a kit designed to run about 7psi...with only a FMIC and exhaust added on...

you didn't meantion a fuel pump or any sort of EMS... ? boost controller...? got a boost gauge ?

pics would be great

I hope you don't mind me posting these, just a couple pics I've found from your previous posts.

wider tires, stickier rubber, limited slip differencial, taller final drive

edit: ...sorry ... wrong answer

i've never put in an aftermarket clutch so i can't give you advice... i'd point you towards centerforce dual friction or star/spec clutches... but that's based on internet hear say rather than first hand experience

hate to tell you this, but you dont have the fuel to run 17 psi. chances are the motor will not last too long at the current boost level

What kind of fuel management do you have to control the injectors? You must have some bad-ass fuel management to run 17 psi.

I got a boost gauge and an air fuel ratio gauge... my air fuel is reading at about .879... my boost is at 12 first gear, 17 second and third never really have a chance to read cuz the clutch is out.... i dont have any type of boost controller... the only thing controlling my boost is the by pass valve... all i did was get the red spring which is rated from 14-20 psi depending how much i turn the bolt down... still on stock fuel pump, 360cc injector.. the only thing ever broke on me was my coil from the distrubutor... i got no traction at all first and second gear.... i beat my friend stage 2 srt 4 and some what hang with another friend mr... loving the 5s.... heheh

yup the picture above is from my recent accident and almost sold it... and yeah this is the 3rd time i bring it back from the junk yard....

i got the hood scoop from a subaru... dont really remember the name of the car... but yup... it's jux a 94 gt

stock fuel... accept for the 360 injectors

>

i know i know... jux the matter of time... but i jux check my compression and still at around 150 psi

>


nope not at all... that was from the accident i had...

wow, so, 17 PSI on a stock 5s, with no fuel management, stock fuel pump, and 360cc injectors... I'm amazed you haven't blown that motor yet! you'd have to be running extremely lean!

that "air to fuel ratio" gauge you have cant not tell you what your air to fuel ratio is. you realize that, right? in order to monitor your a/f ratio you need a wideband. but somehow i think that this advice will fall on def ears.

Some how i cant see you having 17lb on a stock 5sfe. The only way is if you drive like a granny.... I had my 5sfe running 12lb and blew it up. I did drive it hard every day so that didnt help.

How can you have a different boost level through the gears with no boost controller.????

I would sugest you turn your boost down before you catch the bus to work....

even on the gauge you have....you want to be seeing something in the 0.92 to 0.94 range...0.87 is most likely on the lean side of things...but it will vary depending on where the o2 sensor is mounted.

his boost controller is the wastegate spring which seems to be set to 17psi from what he describes. The stock 6G gearing is short. This means that the car is out accelerating the turbo.. So he's not building full boost to 3rd gear.

just to give you an idea (IIRC)
0.87 O2 is around 13.5:1 ,
0.93 O2 is around 12.5:1 ,
0.96 O2 is around 11.5:1

...

If you want to keep running this boost/power level. I would recommend a meth injection kit with a 3.24 GPH nozzle...and of course a better clutch to hold the power

LOL... jux a matter of time before the motor gonna be gone so i can get the 3SGTE.... way more potential to satisfy my need for boost...

This is normal.

I don't get this, you're boosted with the only injectors as fuel upgrade with NO check engine light?

I have a map sensor upgrade so that my computer will only read 2psi of boost... ill take it to the drag this sunday and the new ACT iz coming... ill let you guyz know how i would run...

Get some vids.
