This is for the 2nd gen Turbos.

HKS costs more and I want to know why? Is it because it offers better cooling or has a larger diameter?

Thanks,

The Greddy IC will require making a small pipe to reach the stock turbo, and you'll probably want to add a BOV--the stock one can be used with a little welding. I have had the Greddy IC, and I noticed a significant power increase with the IC while still running 7 PSI boost. I would say to save $600 and buy the Greddy kit.

 

But what are the visible differences between the two? Maybe the HKS one comes with a BOV (I plan on buying one anyway..).

Who sells these intercoolers that would have info about them online such as pictures, sizes, included items etc.?

 

They both look very similar. The piping is even run in the same way. The 87-88 HKS IC is significantly more expensive than the 89-91 model. I have never been able to find out why. You may want to give Mazdatrix a call to find out. They should know.

 

http://www.teamfc3s.org/performance/T2ic.htm may be of some help. It lists the core sizes.

On my convertible I haven't seen air temperatures much above 100 degrees F with the Greddy IC with piping to fit my application.
