Ottawa Fiero Club Forum

Have been doing some research into the new 5300 used in the Impalla Monte SS and Grand Prix and come to the conclusion that it is what I want to do for my next toy.
This should make for a nice install into a Fiero especially if I mate it up to one of those new 6 speed manual trannies. From what I have found this engine is specially made for FWD applications with the over all length shortened by one inch for clearance.
It already has the right bell housing coming bolted to the 4T65E tranny. It also turns out the Vortek truck version has the same balance on the flywheel as the FWD one does and although the Vortek 5300 does not come with a manual tranny the older 4800 version which also shares the same flywheel does come with a manual tranny.
I am thinking it would be best to use a computer from a manual tranny Corvette with the LS6 engine as the 5300 is an LS engine it should be able to run the 5300 with a manual tranny.
Bone stock this engine is 303 HP @ 5600 RPM and 323 ftlbs @ 4400 RPM due to it being an LS V87 there is also lots of after market support available for future mods like say a nice little turbo to give it a little boost.
Does any one see any errors in my thinking or any rason not too do this swap that is besides suggesting to stay with the auto tranny which I am already considering but would prefer it with a manual. Dan

Unlocked! :)  I don't know who did it though.

Continued from PM because topic was locked...

Alternately too Dan you could just put larger diameter wheels on.  That would have the same effect as tall gears, but you'd go though a few more trannys.  Although I'm still on my first (don't drag race though).

That would be an increadable swap. As long as you can get the computer part all ironed out. I say do it! Stick with the standard trans.

Axles... axles.... axles!!! only for you though!! ;D ;D
