Turbo????
So im thinking about putting a garrett gt-45 on my 8 and i wondering if there are going to be any difficulties spooling such a large turbo? im also probably not going to upgrade any internals except injecters. is this going to be ok?

The GT45 might be small depending on your horsepower goals. Might be beneficial to go straight to a GT55. The Renisis engine and all rotaries for that matter have higher EGTs than regular piston engines so spooling even large turbo's isn't an issue, but because of the high RPM and volumetric flow the engine can get choked for flow if you go too small. Also it's best to spool up the turbo with a very lean mixture to get it up faster. The engine itself should be able to handle at least 1500hp, as I'm sure you've read in you research although as with any FI application it will decrease engine life, but these engines have successful gone 200k+ miles before rebuild so they are very reliable to start with. Hope that helps, please post a build thread to let us all know your progress. We would love to see it when you dyno it, especially through a monitor and not in person.

P.S. These engines love unregulated wet shots of NOS the ECU can easily handle the extra fuel with your new injectors. Go for like a 300 shot and you should launch from start like a rocket. And again, please post video when you do.
