Whew!! Got some heads! Have some Q's

Scott_95GT · Nov 15, 2005

I got some near-new GT-40 heads from a friend. They were going in his 89LX, but now he might be selling it.

I was going to do some gears, converter, and a mid-pipe this winter, but I'm thinking I might try to put my cash toward a mild H/C/I setup. If I don't go for it this winter, it may never get done.

Anyways, is a 2031 cam good for an aode? I need a smog friendly, aode friendly, off-the-shelf cam. RR's? Also, I was also thinking of a TFS intake. Anyone with GT-40's and that intake? I'm in the preliminary stages here, and need some feedback/direction. Thanks guys.

the lower of the TFS intake will need to be gasket matched I THINK. not sure though. Not sure about the cam, i've always heard it being used with a 5-speed. I would go with 1.7rr's also. Good Luck, and save and do it right the first time, dont skimp.

The 2031 cam is a great grind and is very AODE friendly. Its designed for GT40 heads with 1.7RR so that would be my combo. I think it was like 513/517 lift. Dont remember the exact specs with that setup. Check the sticky on it at the top of this forum. Another cam you could consider is the Steeda 19 and also comp makes very nice cams.

Yeah I'm going to start piecing it together. My B'day is in 3 weeks and i'm asking for summit gift cards (sounds kinda pathetic because I'll be 23, but whatever works). I'm going to get absolutly everything I need before I do anything. I'm only doing this once.

Cool, thanks. That w/an Eddy Perf. on top is looking like it will be my combo.

Will my stock fuel system be sufficient? If I have to get #24's, a new MAF, and a fuel pump right now, this project might go on hold for awhile because money is tight.

Sorry.... but no. You're gonna need some 24's, and a bigger fuel pump, probably a 190 or so. The maf can wait, IF you have some way to tune around it (twEECer, or custom tune). But I'd suggest getting a bigger one anyway.

Thats what I had always thought, then I started hearing people talk about how #19's will support a decent amount of power, and since GT-40's are mild heads, I thought I might be ok.

Well, I just got done talking about how I wanted to make sure i do it right, and here I am tryin' to cut a corner .

lol

Well, the heads are still good heads, and the cams you're looking at are pretty aggressive cams, along with that Eddy intake. So better safe than sorry. lol, there's nothing wrong with trying to save a little money, you just gotta know where you can and can't cut corners. When it comes to fuel delivery, you can't, lol.
