honda motor? why? the power to weight ratio would be retarded...

as far as other motors go... N* have been done (garbage of a motor), Ls4's have been done (not too much aftermarket) ive even seen a ls7 swapped w-body monte

I was just using it as an example... I wasn't considering such a thing.

Stock is good to 300hp just like the rear wheel drive stock tranny.

Ok so your trans has been going for 174K and that's with the 4t65e-HD... so for a daily driver I could push the engine well over 300+ HP and I should be able to get 170K+ miles on it too? If the 4t65e-HD can handle everything I wanna throw at it then great. Its just with everything I had been reading about the transmissions in these cars, it couldn't even handle the stock 200HP over a stretch of time. But if what everyone here is trying to say is true that the engine is great and a rebuilt 4t65e-HD trans can handle everything I wanna throw at it, then great. That's all I needed to be reassured of.

Theres like what, 2 people that have swapped a manual into a 97-03? And nobody that I know of has tried it in an 04+. Unique indeed.

I've done tons of research on this, its not as hard as people think.

And "Mr. 5-speed" Kuntzie has thrown more HP at his 284 than anyone thought possible. a 6-speed(F40) can take roughly 450HP, the 284 can take 600+??

As far as HP/performance of the 3800, boatloads of reliable power on the cheap! They love boost! No need for a VQ35 or whatever unless you want all the headaches for sht and giggles.

Thanks for the encouragement bro, I read through both links you gave me, amazing information. I wouldn't be brave enough to go it alone, I would for sure need some help with this, and yeah, a 5 speed (284) is definitely the route I will be shooting for. What Kuntzie did there was just amazing, it looks great and the cost doesn't seem bad at all. I really wanna turbo my car and possibly nitrous too.
