Thread: Which Engine to use (98 or 05 SC)???

Well I picked up a 2005 GTP today. SO now I need to decide which one to use for the KIT Car? I will be running headers, Cam and Intercooler. I have the Intercooler and headers. I do have the whole 05 car. It was T-boned. So it's a salvage/parts car. I need your input???? Thanks in advance...

Id use the 05 seeing as it is newer and already has the genv

05 for sure

neither, use a high compression block and the top end of one of those motors. low compression with the m90 sucks.

Well then I been some N/A 3800 pistons then. Anyone???? Anyone?????

its not just the pistons.

OK Bio, I just picked up an 04 GT 3800 NA today. SO I have my 3800 High compression for my Top swap. Trying to decide on what cam??? St1, VS, XP??? Decisions, decisions??? Either way I will have plenty of GTP parts for sale when I finish my project!!!

what kind of powerband do you want?

There is the problem. I'm not sure what would be best??? The Kit is light, so power to weight ratio should be awesome. I will have Isuzu Fiero 5spd with the 3800 S/C. What would be your recommendations??? Thanks again Bio...

honestly with the ability to shift how you want, id put the powerband up top and be done with it. therefore it'd be mild mannered around town cruising, but once you get in the throttle it turns into a monster. in order to do that youre going to want to have a 'big' cam with some high lift numbers.

are you staying on stock heads?

The headwork will depend on the cam. I will probably mill down the valve guides .100 for higher lift cams anyway. That way I can install a bigger cam at a later date if the first cam isnt wicked enough. Either way I will be lightly porting and polishing the heads. Add a valve job. Will also be opening up the cooling jackets in the engine for better cooling.

start here: intense IS3.
