yes, it could be the reason you cannot rev above 4K or the engine breaks up at that point. I however do not see it being the cause of overheating, obviously check the cooling system for that.

 

I have a new engine, new water pump. What else could it be, I was thinking that a lack of fuel would cause a hot burn ( lean conditions)

 

Go get some pb blaster and soak that thing down! I am sure you need to change the filter badly! but put a fuel pressure guage on it and see I am curious?? Check you radiator and make sure the fins are clean

 

I think there is a more serious problem here. Do a compression and leak down test.

 

I'd deffently chnage that filter then check the thermostate. you'd be suprised what a fuel filter will do. f

 

I agree, start with the coolant itself, the thermostat, and radiator. All the obvious stuff first. Also is there anything blocking airflow to the radiator?

 

Have you changed the coolant any time recently?

 

ya, hey, I installed my SAFC, zeroed everything out, and set the thorttle curve downward. Now I can rev up 6.5K in first, 3-5, but 2nd still losses power at 4K-rpm.

Ya, like I said I had the engine replaced 1 month ago, I recently changed teh coolant, I am still looking to change the Fuel Filter, but I have found another problem. I looked right behind my turbo between the head and out to the side, I found a hose that was nearly ripped off from the clamp-on, It has like no oil pressure, leaks, and generally kills itself now, it cant idle. I am guessing that it was there before, but now it is broken off, and my oil is going nowhere- VERY FAST!!! Would that cause it to overheat as well?

Sounds like a coolant hose, do you have any coolant left in the radiator? Post a pic.

 

We put in new supra pump and sx afpr in buddies car.It showed fine fuel pressure at idle. But it did'nt rev worth crap and it was running very slow on our timing equipment.
Also the supra twin turbo pump was very noisy in his car but same pump was dead quiet in my car.
We changed out fuel filter and it was a miracle.The car now pulled clean to redline much faster and the supra pump is once again whisper quiet.
It made a huge huge difference. Car is showing no knock even at near 20psi on stock sidemount 14 with 92 octane and no tuning. He has the supra pump and afpr,new fuel filter ,new plugs Bp7es..COP ignition. K and N filter , 3 inch downpipe and catback and currently against my advice greedy RS venting to atmosphere.
Very impressed and amazed by the zero knock..His has dsm scanmaster.

 

All, you 2G guys in this thread, IT IS A OIL LINE, that is what is rushing out of it.
Technically, it is directly behind the coupler holding my intake piep to my turbo. just look for it, I tried to take pics, but none of them came out.

 

is there a difference between the 1G and 2G replacement OEM filter. If so, what is the difference

It's an oil line not a oil line. Are you telling 1g guys to get lost?? Maybe if you could figure out how to get some pics up, somebody could help you. If it's gushing oil out, how the hell can you miss something like that unless you never look under the hood or under the car? I make a point of doing both daily. If it's a busted oiline, get a new one and fix it, what's so hard about that? Your motor is probably toast by now. Having no oil pressure should have turned a little light in your head on awhile ago.

First off, I did not say anything about 1G, I am saying that 2G guys may have had a similiar problem , I have 2-95 TSI's, 93 GSX, 91 VR-4, and a 93 3000gt VR-4. I also look under my hood everyday, it wasnt leaking any oil at all before, but now the whole line snapped, so it all came out, obviously i have no oil pressure. So I havent turned the car on since it happened, Then I replaced the hose.
BTW,- It happened all of a sudden, DUH, if there is no oil pressure thats bad, Its not like it gradually went down. Stop being a Smart-ass to me in EVERY one of my threads.

 

It is a coolant line... From another post you made you said that its the line from the water pipe to the turbo. Yes, that line contains coolant and not oil. If it has large amounts of oil in it, that would explain your overheating. This sounds like a very badly blown head gasket. DEFINATELY not a fuel filter problem.

 

Why does it drive and run fine, doesnt surge at idle, and now the gauge is showing good oil pressure, there is just a oil leak., I comes from the head, right behind the water pump pipe, My car idles at 900, drives good, revs to redline fine, doesnt sputter/misfire, doesnt blow smoke ( any more), and now I have replaced the hose, but I am still leaking oil. however, the hose I was referring to was still ripped. Myabe the hose wasnt put back on correctly, I got back under the car, and tried to take pictures, my camera is screwed up, so sometimes it doesnt show bright, so there useless. it definatly connects to the turbo, it looks like the feed line, b/c the return goes under teh turbo to the oil pan i believe.

 

But I have has this overheating problem before and after a engine swap, 97' model 7bolt, 70k miles, never had a problem before, once it is in my car, it goes bad. I think it has nothing to do with engine itself. B/C most of these problems were present before I swapped, now I have a newer motor, and the same problems still there.

 

Does the line come from the water pipe as you stated in another thread or does it come from above the water pipe from the cylinder head. If its a line from the head, that is your oil feed line to the turbo... you need to be more specific about this line.

 

There is a big pipe running in front of the engine ( water pipe), there is a little pronge ( 3") that sticks out from BEHIND this pipe. It looks like it goes into the head. If it were a water line, wouldnt it be more logical to tee the pronge off at teh very base of the pipe.

I have one stainless water line coming from the top of the turbo- loops down under and bolts to the motor.

I have one blue "L" shaped hose that goes directly from the turbo to the motor.

Then I have a black generice hose that mounts to a pronge coming off of the bottom of the turbo ( S16G) and goes up runs next to the wastegate, snakes up, and attaches to the pronge from behind the water pipe..- this is the on I am talking about.

I thought there was only one coolant line from the turbo, and a return and a feed line ( oil) from the turbo, I assumed this was the feed line.
