Of course it depends on the quality of the job. If you do a crappy job you can screw up the TB and your car will run like crap
A good job should allow for maybe a few ponies and a few ft/lbs of torque.. don't expect anything major liek 10rwhp or anything

I figure that I'd just buy an aftermarket TB first, then maybe port the intakes somewhere down the road
the upper isnt, but the lower is, especially on single ports. the split port upper flows really well, and the lower flows decently. but the heads are still the most important
Heads ~ 20rwhp
Lower ~ 10rwhp (if ported well)
Upper ~ 5rwhp (if fully ported)
Heads ~ 20rwhp
Lower ~ 10rwhp (if ported well)
Upper ~ 5rwhp (if fully ported)

Cool, thanx a lot guys. It's just something I've been thinking of for somewhere down the road. Could you point me to a site that would show how to do the heads?
Its not recommended that you try doing the heads yourself if you have no experince with porting intakes. heads are tricky and need to be done right. If you have some spare heads you can port than that will be the best aay to learn. As for sites I will lok for some.whipster24 said:

Granted, none of the links that I tried on that site worked
I do 1 cylinder on V6 heads for DIY'ers and then they have a pattern to
follow for the rest of it. Substantial savings! It is also marked out for the
port match and everything, I can even rough in all the exhaust ports cuz
of work to the valve guide, it is lots harder than the aluminum.
The savings are around 75% or so, depending on the level of porting.
I can do the same for intakes too. Core charges apply if I supply cores.
For the 94-98 style, it is a bit more cuz I need to do an extra port
(the dogleg center port is different shape) but it is reasonable.
With a cam Monkey's esimated #'s go higher
But he's pretty close. It's possible to get 100 RWHP
total with a complete package if the porting is right.
It also needs a tune and fuel upgrades for sure.

What would you charge for porting the single cylinder on a set of heads for the 94-98? Please include the core charge. I'm thinking I'd like to have the extra set in case I messed something up ya know.
I was thinking about getting a supercharger in January (tax return) But if I can pick up significant HP with P&P Intakes and heads plus Cam for much less then I might have to go with that!

I usually do it all core exchange, so the install is at your leisure.Fishers Stang said:
whipster, you need to fill out a cam form or at least tell me the
combo you wish to have, then I can tell you what porting you need
and can work up a price. It would be between $125 and $250
probably. I can also do a BV package like that, supplying all
valves and the bowls rough cut for the big valves too, that would
be about $600 for that type package. You finish the porting
