what are your long term plans for the car? i would say 65mm would work well with what you have now.

long term plans could be new heads but would be a long time but, i may do these few mods and be perfectly happy with it and keep like this for a long time and maybe a lower gear.

IMO, even with heads you only need a 65mm.

I would just throw a 70 on there if you dont plan to ever boost it. 5 mm is not going to make that huge of a difference especially if later on you do heads. You will have a good size tb for it. Plus i wouldnt pay 150 or 200 for a tb if your only going to get a 65 when stock is 60, mine as well get a 70 so you can actually tell the difference.

i have an accufab tb on mine, would buy it again.

but bigger isnt always better for throttle bodies

You'd be surprised. C&L claims their 76mm MAF flows 100 cfm more than their 73....

Saleen, you need to match the parts. W/ stock heads, the stock cam is really enough.... If you insist ona cam, the TFS Stage 1 is better than the Ford letter cams b/c it has a higher lift and duration on the exhaust ports, helping to compensate for the smaller port size and thermactor bump blockage. The TFS Street Heat is matched to go w/ the Stage 1's rpm range, the Track Heat has a higher rpm range.

A larger TB won't do you any good if you still have the stock 55mm MAF. When you upgrade the MAF, the 65mm TB will be plenty on stock E7's....they'll be the bottleneck.

what size maf do i need? and when i upgrade that, which will be when i put on the intake and cam do you still think the 65mm or something diffrent.

Always get your MAF bigger than your t-body. My t-body is 70mm, Maf is 73mm. I would still get 70mm t-body in your case though.

There are lots of combos that will work well. I'm running a PMAS 75mm MAF, 19's, and a 65mm TB on my rebuilt 306 (E cam, 1.6 rockers, ported E7's, TFS Street Heat). I wouldn't go over 70mm on a TB unless you're running boost.
