I am currently in the process of looking for a compressor wheel. I am either making the kj-66 or gt-2000. Both of them require a 66mm (approx. 2.598 inch diameter) compressor. I found a a very cheap compressor wheel from ct-26 equiped Toyota Supra. However, the dimensions are just slightly smaller. The inducer diameter is 1.775 (45.085mm) and the exducer diamter is 2.558 (64.9732mm).


Do you think this small change in diamters will make a difference. Is it possile to use this the compressor if I tweak the difffuser dimensions? What else would I have to change and how should I go about changing these things?


Thanks
