SRT-4 Intercooler

[RayG1988]

Has anyone ever used these in an s30? I have an early model 260z with an NA L28 which was turboed. I was wondering if anyone has used these before and how good they are. Theres someone selling one on a local forum for 25 dollars and I was thinking I could possibly buy it.

 

Sorry I don't know the dimensions, the seller didn't specify. They just said it came out of an SRT-4.

 

Here's a picture:

It's pretty wide, and would think too wide for an S30.

 

I installed one in a 1994 Cavalier, required modifying and adapting other end tanks.

 

You'll want to change one of the tube ends anyway as it necks down to a small oval pretty badly.

 

For $25 it's not bad, but I would wait for something that will fit easier and work a little better.

The oval-tank side doesn't decrease in circumference. I have one in my garage which I used in my XR4Ti and I was quite satisfied with it. I think it actually fits very close to nice in the front of my 280Z, except a little too NARROW (~2"). Seems like some massaging of the holes on either side of the radiator might allow it to fit beautifully (ie the end tanks would go right through). However, you'll probably find you'll want to hack up the end-tanks some... or a lot.

So general consensus is find another one better suited for the s30?

 

Gonna start looking some more. Thanks for the advice, guys.

Also, another thing to consider. The SRT-4 put out ~230hp at the crank. You are going to be probably putting down ~350 at the wheels eventually. The rule of thumb on using other car's ICs is never go with something designed for LESS hp then you are going to be running.

 

Hell, I put down 230hp at the wheels NA....

Hmm...you're right, while it may save me money now I'll have to end up buying another one later. Guess I'll go look at the L28 turbo sticky and see if I can get any of the intercoolers they recommended in the thread and I'll look at other L6 builds for ideas.

 

Again, thanks guys.

That doesn't quite work out, though. How much power have plenty of those cars made with stock intercoolers? I don't know the answer, but I do know turning up the boost on them and opening up the exhaust can get you to 300HP pretty easy. For an example of something I DO know: lots of TurboFord guys use intercoolers from all sorts of cars and make gobs more power than the car their intercoolers came from. What about turbocharged vehicles with no intercooler? Early 300ZX and Merkur XR4Ti for starters.

I didn't say it was on stone tablets. But especially with modern cars, ICs tend to be as small as they can be to still operate reliably. Obviously, the design of the engine comes into play as well. But if we take it as a given that most ICs on factory cars are designed specifically for the application they are being used on, they become the limiting factor on an engine that they are grafted to. Either you can't push as much psi, or the air that you are pushing is not cooled as well as it would be with a different IC.

 

Obviously, internet wisdom is generally worth what you pay for it, but if I was doing an L28et build right now, I would probably spend the extra money to get not only an unused IC, but also one that is good beyond the power that I am actually looking for (though that also has to do with the weather I would be driving in).

 

Actually, thats another factor. The weather that the OP is going to be driving in can also determine IC size. If they are going to be running this car in say, the middle of the desert during the summer, for a given whp number, he is going to want a larger IC. But if they are running north of the Arctic Circle during the winter, they can probably get away with a smaller one.

 

 

Ok, thats weird, this feels exactly like another post I made at some point on a different forum about IC sizes....

Hmm, well I want to get a better one but still for 25 bucks I can't go wrong. Gonna look it over, my Z doesn't get here until the 7th. If anyone can tell me how much space I have that'd be awesome. That way I can go look at the intercooler for now and see if I can make it fit inside the Z.

 

I got this information from the seller: 24.5" W x 5.75" tall x 2.75" thick

 

I'm going to see if I can go look at it this week and see the condition, if it's not that bad I don't see why I shouldn't use it temporarily.

 

I mean how expensive would it be to get the piping done? lol

just over two feet x one half a foot x almost three inches = sounds like it will fit.
