LQ1 into 2001 GP?

[2bzbat]

I presently have a hi flow TB from ZZ performance on my 3800...would that be suitable TB for a 3500? That way stock cables for both throttle and cruise should hook up.

Thanks a bunch for the input on this...sounding like better idea all the time. The LS4 would still be cool option but I've been told the engine bay will be a bit cramped since the 04 GP has slightly more room underhood.

A 300hp n/a V6 would be a better option I think, lighter weight and better fuel mileage (or at least comparable.)

I'm not sure if that TB will fit the flange, but anything is possible with a drill bit and a tap set.

I was looking on a wikipedia page about the 3.5 and it seems like the LX9 would be the most compatible with my chassis.

Does that sound accurate? 2004-2006 model years?

What performance mods would you recommend to hit the 275-300hp range?
