NON intercoolded turbo
i am currently installing a t04 hybrid turbo on my n/a rx7 and am planning on keeping high compression at like 5 to 8 psi of boost, so that means is gona yeild high power but what i am wondering is, do i have to run an intercooler or what? what do you guys suggest?

... wo....
I have to ask questions first...
a)do you realize that you have high compression rotors. and would require to run less boost from preventing from detonation?
b) do you have a reliable and good way to control your fuel as the boost increases? Ie. fuel controller of some sort of perferably Stand Alone
c) Do you have the fuel system to support the extra feul needed to prevent from detonation?
d) How many k's on the Engine?

my Engine has recently been rebuilt it has about 2,000miles on it and i am planning to run 5 to 8 psi of boost . my mechanic said that highest i should go is 8 psi, and he said that he would set up the fuel system for me ... but then i had to leave the shop and i forgot to ask him about the intercooler

Ok,
a) assuming he does adiquately set up the fuel system, you need to adjust the amount of fuel added for amount of boost added correcting for your higher compression rotors.
B) you will want to have an intercooler mounted perferably Front mounted. because if not then your intake charge temps will be SIGNIFICANTLY HIGHER and you will need much more fuel to compensate.
C) Yes you would be well advised to have an intercooler, and you would be even more advised to get something to control your boost because your N/A stock computer doesn't have boost maps. so you will need something to adjust for boost as I mentioned before I stress this.

I recomend making sure the line going to your wategate is nice and secure so it doesnt pop off like mine did and spike to 18psi. hehe
but other than that, you should definatly be setting a stand alone computer, at the very least just a fuel only one like I have in mine, and using the stock N/A computer to run the spark.

Haven't we ALL heard this
If you are trying to stay cheap. Run with out an intercooler carfully. While monitering your AFR and intake temps. I do rememember that somebody did some intake temp tests with a stock TII setup. The intake temps were exceeding 250F. A little toasty
See how that goes. Then if it is very hot try going with water injection. Very possible to use the water to keep it cooled off.

Water injection is a great idea, but putting a nice big FMIC in first would be alot cheaper in initial outlay than even just a simple water injection setup.

That will lay it out for you very nicely. Click on technical as it applies to a NA. However, it is even better for forced injection.
Also, you can buy the basic kit for $420. This kit basicly sprays at a certian psi.

To spend all that money on adding a T04 and then run around with low boost and rich mixtures to avoid detonation would be a complete waste. You would soon get frustrated with the complete lack of potential. If you're going to do this, don't do it half-assed. Do it properly with a decent-sized FMIC.

NZConvertible is on the money with this one, definatly don't run this setup non intercooled, run a FMIC of some sort.. even a Stock TII cooler front mounted would be a huge improvement over none at all.

Do they make any big side-mount intercoolers for track/road racing or some other efficient layout to avoid overheating? I know it's nearly impossible on a turbo to avoid eventually overheating, but what is the best layout on, say, a 300whp car.
Thanks,
Jeremy
