2 not blown
I have a 92 Prelude that has the H22 motor swap, and have been boosting it for almost 2 years now, no problems, and the motor was and still is COMPLETELY STOCK. I am running a Garret 60 trim t3/t4 journal bearing turbo, one thing people overlook, I have an oil restrictor on the oil inlet (too much oil can destroy your turbo, blow the seals). I am running a Spearco intercooler, Greddy Type RS blow off valve, Turbosmart 35mm wastegate with 10lb spring, AEM fuel rail, Hondata heatshield intake gasket, RC 750cc injectors, walbro 255lph fuel pump and Hondata S300. My car is tuned at 10psi and has been for almost 2 years now, Dynotuned using a PLX wideband to feed the S300 and last tune (6 months ago) turned 415whp on 10psi of boost, COMPLETELY STOCK INTERNALS!! As for my experience on ANY motor, a proper tune will determine how reliable your set up will be. I have a friend who also has a stock H22 with an Ebay t3/t4 turbo, but quality parts (blow off valve, wastegate, injectors, fuel pump) and he has been running his on 10psi as well for a year now, no problems. I believe his pulled 350whp on his last tune (different turbo compressors have different compressor maps, therefore = different results). My advice to anyone building a turbo set up on ANY SERIES OF ENGINE, if youre not looking to break speed records and want something that will be reliable and fun, take your time, spend the extra cash for a Hondata S300 (or any reputable management system), use a wastegate with the proper spring for the amount of boost you will be running (for example, if you want to run 10psi, use a wastegate with a 10psi spring, dont waste your money on a boost controller, use the Hondata or other management system for that, afterall, you paid for it, and have it tuned properly), and have fun!
