just wonder if is possible to lower the comp. on an n/a so it could handle turbo better???

turbo rotors...i cant think of any other way safely...but you might wanna see if any one else has any ideas.

The only way to do it is to take the engine apart and replace the rotors with lower compression rotors from a Turbo II. The '87-'88 T-II's had 8.5:1 compression. The '89-'91 T-II's had 9.0:1 compression.

If you can find someone to machine it for you, it can be done. But yea the easiest way is to get a pair of used TII rotors.

But why would you want to? Once you've gone high-compression-turbo, you'll never go back.

yea, why would you want to? high compression will produce a lot more power.

how detremental would it be if i were to rebuild my 89n/a engine and turbo charged it?

jhammons01

Just drive it lots!!! After about 100k the compression will be much lower

-OR-

Take the exhaust off and using a long drill bit, drill out the rotors via the exhaust ports. Adding the holes in the cavity of the Rotor will lower the compression.

If you listen to me......well your dumber than I sound

wont turboing a high compression rotary increase the likelyhood of detonation if it isnt tuned to the utmost precision?

If its not tuned correctly, yes. Ya can make more power with less boost with higher-compression rotors.
