Hi

Im aware with the first Hks 7460 there were issues with it and Hks released a second being the Kai which solved this or either more reliable.

question i have is how does one determine if its a kai?
should it be stamped on the plate of compressor housing or by numbers.

The one i have is Hks Gt2 7460r so not sure what the R stands for and getting mixed info on google.

Thanks

 

KAI says KAI on the spec plate. My original from promotional sale package with HKS 274/278 cams is still going with no issues, many miles after, use on 91 and E85, track, everything. 50,000 miles easily.

 

Ok thats good for reassurance it’s possible.
how much boost are you running?

 

Someone else has it now, and his top end is 28psi on E85.
I ran mostly 91 at 24-25psi, and E85 to 29psi.
