I have a fairly large KKK K30 off an industrial generator and the person I bought if from is going to give me the second. Its a really old design that despite the size, the compressors are only efficient to about 325hp each @ ~10-15psi and 80,000 rpm max. I have been told in a previous thread(https://www.theturboforums.com/smf/index.php?topic=32668.0) that they have 25cm hot sides and that this is borderline large for a 302. Now that 'll have two, I'm exploring the possibility of using both turbos in a twin setup, but with drastically smaller hot sides.

How small of a turbine housing can I get for these? I've heard of 17cm housings, but wont that still be too big for twins? Are these parts even still available? I found very little online.

Thanks.

 

New or used, I dont care.

TTT^

 

If you are going to have to custom build a setup around an old outdated turbo to save a few bucks, I would think to get something more common place for a turbo and fabricate.....I think it would be a waste to hunt for something old just to save a buck...

 

The turbos are outdated by today's standards, but I would say only because they have a narrow efficiency range. They're still very useable. At 300+hp a piece, they're still more capable than my block.

The purpose of using old turbos is so I dont have to spend $1400 on some Garret GT turbo. The added bonus is the sight of two HX40 sized huffers under the hood and besides, how many people have even seen a K30? Perhaps not the best reasons, but the plans are set. If things go to hell, I'll just Ebay them.

Maybe I'll ask this in the JY forum instead.
