'86 engine to '91? how many hp does a '91 E got? what changes do i have to do to gain?

Jus how much more are ya lookin for?

Could always go TI or TII? Or 20b if ya really want some power.

91 n/a engine has 160 hp...



86-88's hae 140 n/a hp



you mean changes to swap in a 91 motor?



or changes to compensate the difference in hp?

https://www.nopistons.com/forums/pub...IR#>/dunno.gif wow i need some more info. swaping an 86 to an 91 is definately not worth the extra 14 hp. unless you love the knowledge you get from the learning experience.

do what i did.. put S5 rotors in your S4 motor.. then port the **** out of the S5 intake and vala half a S5 motor, you also might want to open up the exhaust a lil bit too with a header.. stay away from the paceshitters, spend the extra $100 and get a Racing Beat header.. they work great..

hope this helps Dave

Dave you run 14.3? with that n/a?

i hope your rear bumper doesnt go up with those 4 feet of flames https://www.nopistons.com/forums/pub...#>/biggrin.png

notice the 150 shot of nitrous... https://www.nopistons.com/forums/pub...IR#>/smile.png

14's are nice for N/A. although should be 13's with NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOSSSSSSSSSSSSSSSSSSSS ss

the nitrous is under his soon-to-come mods though.
