hey, question, can you use the cooler that is for the power steering (the little radiator type thing right under the PS reservior) as and oil cooler for your turbo, would it work good?....or am i oblivios and people have used it before ...comments?...thanks

stupid question i guess?

I really don't like oil coolers. My "opinion" (only what I've experienced, seen, and feel) is that if it's not plumbed in by the factory on a (even turbo engines) that it's good enough. Filter relocation kits, and oil coolers were not in the engineers plans when it comes to oil circulation and the psi of their systems. It effects the oiling of the motor and has lead to several "run dry" situations on 3S's with them on causing them to spin bearings. Say you wanted to swap the oil cooler from a GTi-R onto your US spec SR20DE, then I would say get their oil pump that is designed to handle the extra flow. I have always felt that you can't beat what the factory put on the car and their engineers are always the smartest when it comes to these systems. This is just my opinion...and I'm not an engineer either.

If u need an oil cooler I have one.

im not exactly in need, but thanks for the offer anyway, i was just checking out my scrap car the other day and was curoius if it would work or not, thanks

Wouldnt it be easier just to swap the BB oil cooler since it uses the same oil pump as the usdm sr20? I think size wise there pretty much the same.

I would have to say no to that one. If your turboin a car u should add a oil cooler to help keep the oil temps down and make your engine last longer. If u road race and have a front mount you will love a oil cooler it will help u from overheating.

I've heard of and known several guys with motors (specifically 3s's) that when rebuilding a motor throw on an oil cooler. The next thing they know is that they've spun a rod due to starvation of oil. You do an oil cooler then throw on a relocation kit and your chances of blowing your motor has just double. The GTi-R motor was designed for the rigors of all types of racing. It's oil cooler should be efficient enough for a street driven car that sees some time on the track. I just am paranoid, from what I've seen, by people messing with their oil system.

I doubt it was the oil cooler that made them get rod knock. It might have been how they rebuilt the engine for who rebuilt it. I had someone rebuild a motor in one of my older cars and it didn't last 1 day. Infact it just didn't get rod knock it throw the rod throw the block. It's all in how u get the rebuild done and how u break it in.

Can you just install a small oil cooler inline with the oil feed before the turbo? this way, it would provide the turbo with more cooling properties. Or is it always best to use a relocating kit?

Another thing you could do is have the bends in the oil gallies and passages ported/smoothed out. This is what im doing. The bends in the passages especially 90 degree bends can be equivelent to 5 feet of hose. My builder who builds L-series and Ka motors has gotten 10psi just by smoothing the bends in the oil passages. This is without shimming the pump or going to a higher volume pump.

Good lord man think u have enough SE-R's!!! hahaha :D

I agree.

I have a friend and he thinks the same way as Chris Colburn does. The oil cooler really has no bearing on the oil pump.

1) Oil pump puts out volume.
2) As long as you don't add demand to (put more leaks in the engine) it you won't have a problem.
3) Oil psi is determend by total amount of leak in a engine i.e. oiling holes for the crank rod bearing, main bearing, camshaft bearing.
4) By adding a oil cooler you are not changing anything but the capacity of total oil in the system.
5) Why your friends spun bearings after rebuild I don't know. I can only guess that all the damage was probably done on the initial start-up and not priming the oil cooler properly.

NOTE: The VVL engines probably got bigger oil pumps because they have more oil leaks, maybe the VVL solenoids are oil actuated and there are more cam lobes, who knows? I'm just guessing.

That wouldn't work for shit.

Its not long enough, oil will go from one end to the other in a heart beat. That little thing would have to be sprayed with NOS while driving just beging to even start cooloing oil. You need air flow over the oil cooler to cool the oil on a non water-cooled oil cooler.

Actually i sold the 91 =). I also have the 94 forsale which i did a jdm swap in and the disease now progresses.

Actually the sr16ve and the sr20ve have bigger oil pumps...so you were right....also if you go with a high volume oil pump you should be safe running a cooler or a relocation kit or both..by doing so you can increase the system capacity...

AFAIK my GTiR doesn't have a factory oil cooler.I've bought a 13 row Mocal one with thermostatic sandwich plate though as I have seen oil temps as high as 130 degrees celsius(normal running is 90-95)on track and had to come off to let it cool down.

skid, our oil cooler is what the oil filter screws into....its a coolant to oil type cooler.

yah its a bolt on kit for a gti-r ,with USDE's and other DET's the oil pickup location is different. If your using the VE pumps on anything but a GTI-r you will need to figure out the proper location and angle of pickup point. Or if some is willing to part with the VE upper/lower oil pans would be nice to. I wanted to do go this route but no one has seem to do the conversion on a USDE or DET (non-GTIR).

Sirnixalot-is it a heat exchanger then?
