not possible, sorry i have 2 stealth es's they're dohc one is 5spd one is auto
mine are both 1stgens as well

 

are there any major upgrades that i can do to get major noticable power... sofar all i have is a short ram intake and a cat-back exhaust... as far a headers all i found was some from 3sx.com but they are worth a pretty penny...... any suggestions there??

 

check out obx on ebay i had some really good luck with some from there...check out 3si.org

 

Between the SOHC engine and DOHC engine, there are VERY few common parts between them. They include the rear main seal and retainer, water pump housing (pump itself is different because of the pulley) crankshaft, connecting rods, and maybe one other small item I cannot think of. The blocks have substancial differences. The only way it can happen is to install an entire DOHC engine into there.

I just got done rebuilding the twin turbocharged engine in my '92 Stealth.
