Hey guys,
I recently just got my 5sfte set up installed. Turns out the turbo that was sold to me had oil spewing out of it like no tomorrow when under boost. Basically I got screwed over by a forum member on mr2oc.com. I was wondering how much a brand new ct-26 is from the dealer. Does anyone know the ballpark range?

Also, after putting in the turbo, there were clearance issues with keeping the radiator fan so that was taken off. I was wondering how you other 5sfte owners keep your car from overheating. I was thinking about hotwiring the a/c fan to keep turning to cool the radiator. Would that be sufficient to keep the motor from overheating?

Little over a grand I believe for the CT26 setup.

Thought it was $1200-1400. (asked when I called for an actuator and thats the price they gave me and said they cant sell it seperate)

sorry for your demise my friend. I also got a busted one. From a local. Anyway. to solve your fan issue it is required to cut a little of the shroud out, I did it with a cut off wheel. The fan will not hit. You NEED the fan, do not leave it out. You could have your blown turbo rebuilt for around 300 i think do a search on that to be sure.

Absolutely MOST have that radiator fan going, its pretty much the only form of air flow up to around 30mph. HIGHELY reccomend you get one installed, perhaps a dual pusher spal setup in front of the radiator, like so:

I'll sell you my JDM Ct-26 :) Been boosting fine for 100k miles or so, no shaft play, no fin damage, etc..

Be a bad idea to by from the dealer, waste of money. If your going to spend 1k, by a real turbo :)

make sure you have a restrictor on your oil lines. thats normally the cause of most of the smoking and oil burning issues with the 5sfTe guys.

i took my rad. fan out as well but i am going to get a small but powerful flex-a-lite fan and put it in the front of the radiator.

How did you cut the shroud? Can you post some pictures???? It would be GREATLY appreciated. Driving the car home not being able to boost was one of the worst experiences i've had in my celica.

Do any of you guys have the dual pusher spal setup in front of the radiator? PM'ed you about the turbo.

Lagos - Can you tell me more about the restrictor?

Read the whole thing. Didn't see anything about the restrictor. Can you point it out for me?

Also another question popped into my head. How much timing are you 5sfte guys pulling for your set up? What boost are you running?

Pressure2 is running 11-12 PSI and 13 at the track in his words.

whats your setup like? list everything you have.

i dont think hes pulling any timinng out, but he did do over 30 dyno pulls. make sure you book some dyno time as well, and learn what you should/shouldnt do when tuning these engines. ill try to find out were he got his restrictor from. you defienty need one or youll be going through turbos on a monthly basis.

that should be the one you need, but doubble check with presure2 to make sure its the same one he uses.

I have:
- ct26 turbo
-3sgte manifold
-fmic
-fmic piping
-bov
-rx7 injectors
-safc ver 1
-msd btm

-tapped 5sfe oil pan
-NGK BKR7EVX-11 gapped to .030
-2 bap map sensor

That's all I can think of off the top of my head. The actual list of stuff I bought is in my binder at school (i'm at home right now).

I seriously need pictures of the fan. I need to know how much is cut so that I can settle this overheating problem. Just purchased another ct26 from ty_44_69 so hopefully that will settle the turbo problem.

Here are your fan pictures. I just cut the outer shroud off, didnt seem to affect it. I used a cutoff wheel to do it, takes five mins. You better be glad i love my celica more than my guitar, oh and heres a teaser pic, heheheh.

your welcome. and I have a 3 inch downpipe. fits fine, Ive already had it on and off once. Lemme know if you got any more 5sfte questions. DONT forget to pull your timming down. I had mine at 6 although i heard 8 was fine. Enjoy.

without the restrictor in the oil lines, your problem will come back.

I didnt run any restrictor on a turbo with 50k and had no problems.

be careful with the boost on the 91, you dont have a knock sensor, which imo, is vital to the life of the 5sfte.
art listed the right restrictor.
you should be using no larger than a 3an line, without the restrictor first, and if the car smokes after stitting at idle, then use the restrictor.
i am not using the BTM, and not pulling any timing at the distributor.
you need that fan desperately.

Ty_44_69 also supplied me with the restrictor and line so I'm not really worried about that. Is your timing set at stock? I'm definitely putting the fan back in. Having the coolant overflow from the reservoir cuz it was boiling was not cool at all. I think I run way too rich without the MSD BTM. Even though I leaned out the fuel curve as much as I could with the SAFC, it was still running pretty damn rich. Around 10:1.

andy
09-05-2006, 01:06 AM
10.1 is fat. I shoot for 11.5-11.8, mine with the 315s and no external tunning was running 11.5ish at full boost. I did not run a msd btm. have fun.

Ok guys. I got the radiator fan back in. It doesn't overheat or anything while driving. BUT when I got home today, the coolant was boiling once again even though i sat in the car and let the fan run for a while. The coolant started to seep out of the radiator hose with bubbling.

Would the issue of overheating be solved if I had a working turbo rather than a blown one? While driving the engine temp gauge is in the exact middle between max and minimum. Getting a working turbo would also get rid of the smoke coming out of the exhaust when under a tad bit of boost right? I kept it out of positive boost while i drove until I got home. I'm tapping the throttle body heater circuit for the water lines.

I'm afraid that even though I put in a different turbo with the restrictor and water lines, that I'll still have this overheating problem. Give me some suggestions guys. I'm in a real rut and the parents are getting really impatient.

I would defiently go with a full flush. I would check the lines fo rthe turbo coolant and make sure no air is getting in those lines (if you tapped the ones for the TB heater, those are a bitch to get tight without it seeping coolant, atleast for me). Flush it, pressure test it even. Make sure your coolant system is okay.

Could be a blown HG..... what color is the smoke out of the exhaust. If its white... I would suspect the HG for those 2 problems. If its a darker color, too rich if its black, or the turbo is leaking, blue. If its leaking.. time for a rebuild or a new one.

bloodredgt

the smoke is blue. No white smoke at all. I seriously hope the HG isn't blown. A flush should be good for it too. I plan on giving it a nice coolant flush when I install the new turbo.

i am running a -4 AN line with no restrictor, and i dont get any smoke.
i just had to cut a small section from my fan shroud where it was interfering with the turbo.
and if you pull your timing, going back to 8 is plenty.
6 is overkill and will severly hurt performance.
i have a BTM and am pulling .25 */lb, so rougly 2* total.
and the new turbo will only fix your smoking problem if thats the cause of it.
im not sure about the boiling coolant, but good luck.

take off your DP and/or intercooler piping and check to see if its oily'

andy

man i had this happen to me. I just pulled the entire thermostat out of the damn car. After that and a good flush, filled with antifreeze/water it never got over 190. I would try that for a quick fix.

no need for a botch job on the fans..... they are like 30 bucks for a slim line fan on ebay that pulls good cfm, you dont need to buy a new turbo send your old one out to g-popshop.com these guys do good work ! they charge about 275 returned ship for a standard rebuild if you need a compressor wheel or shaft it will be additional

I finally finished with finals and have set aside the majority of tomorrow to swap the turbo out for another one. I'm going to check the intercooler piping to see if there's any oil in it to make sure it's the turbo that's giving me the problems (at least the majority since it's spitting oil out of the intake side). I'm planning on flushing the cooling system too. I'm also looking to install my BTM, but there's a connector that I'm not familiar with. It has 4 line connector but I have no clue how to hook it up to the car.

I've already hacked my fan shroud so I doubt I'll be buying any slim line fans anytime soon.

I'm just worried that my headgasket might be blown. If there's no oil in the intercooler piping, it could also mean my piston rings are shot and that's why it's burning so much oil under boost.

To make sure I took a close look at the smoke (at idle of course) and it looks like it's blue, but it has such a nasty smell to it when it burns and comes out of the exhaust, I'm afraid that the headgasket did pop and a bit of coolant is mixing with the oil. I'll hopefully have answers to all of these tomorrow after I pull off the turbo.
