I'm about to order a trick flow street heat manifold with 70mm egr and throttle body. I did a search and foundn that some say 70mm is too big for an other wise stock engine, but 5.0mustang and superfords did a bolt on test with one and got 43 hp... So will it be ok or should I go 65mm (nitrous or sc is comming in the near future).

Oh, and does the intake manifold, throttle body and egr come with gaskets?? i couldn't find any info on the website.

thanks

About the gaskets... I would call up wherever you are ordering from and ask them. As for the TB, a 65mm would prob be a little better but with a 70mm you always have room to grow and its not going to kill you. I ran a 70mm tb on my 88 GT with bolt ons (full exhaust, u/l intake, pulleys, etc.) and it was fine.

I would like to point out, that the opening on the TFS Street intake is 75mm. If you do have a supercharger in the future, you might as well get the 75mm T-body. You can use your stock t-body for the time being until you figure out if you want to get nitrous or a supercharger.

If you do need to get gaskets here's some:

I think its a 70mm opening on the street heat.

Nope its 75mm (Must have just changed recently because I also thought it was 70mm)
