i just pulled my 86 gl turbo wagon motor apart for a rebuild. it has an ihi turbo, is that stock? oh yeah and higher compression.... i have a non turbo motor sitting in my shop. how reliable is the higher compression? also is there any cross over type stuff like turbo pistons in a non turbo block or non turbo pistons in a turbo block?

 

 

thanks

ihi turbo is stock.

yes you can put non turbo (higher compression) pistons in your turbo block but be very careful. it's possible and theoretically should be fine. many people that have done it have had problems. if you're going to fire up the boost and "play", best to keep the turbo pistons.

 

have you thought about an EJ swap? by the time you're replacing main bearings, rod bearings, rings, and spending all the time and money or machine shop work you might be better served with an EJ22 or EJ25...and those are easy to install a turbo on as well if you wanted to.

yeah, i think i'll just go with all the original stuff, just intercool it or something. thanks for the help, you caught me just in time.
