I posted this over at 60degreev6 but I thought I'd repost it here so u guys can chime in on things also
I have bought a 96gtp that had bad heads from the valves being bent by the broken timing belt. I have since gotten another set of heads surfaced and pressure tested. I have ported and gasket matched both sides of the heads.
As I was thinking about the job ahead of me of replacing said heads I thought I'd also throw on my ported lower manifold and custom short runner upper plenum with a northstar 75mm throttle body.
Then I started researching and all I can find out is that most people go boosted when they want to get power from these motors. So me having a love for these motors but not wanting to be like everyone else, have decided to build a NA one just to see how much a person can get out of one.
I have a set of SLR reground cams and will be putting those into a set of 97 cam carriers, and milzy has emailed me back saying that he does still offer 3.4 Dohc headers. So next month when my taxes get back I will be ordering them. I will also be ordering hptuners as then I can tune my Fiero (also 3.4 Dohc) and my Gtp.
I have a FFP UDP, and I have quoted a set of 11 to 1 high compression pistons out from je pistons ( and can get them pretty cheap because I know some of the people who actually make them). I will also be balancing and lightening the whole rotating assembly. I will also be running e85 with 42.5lb injectors
I'm hoping to get 300whp with this setup. Through a 4t65e trans.
