i have a stock 92 lx with jba ceramic coated shorties and 2.5 inch exhaust and flowmaster 40 series mufflers and 4 cats just wondering how much more power it would be putting out with out runing it on a dyno and what i should do to it next

heads cam and gears

92redfox · May 11, 2011

do you think i would be better off buying a peformance package for the cam and heads or just buy each part individualy

if you do buy a package deal get the trick flow or edelbrock. but if go with trick flow and get the twisted wedge heads you will need new pistons. always with aftermarket heads check piston to valve clearance. stock pistons cant handle any more then 1.90 intake valves. i learned this the hard way with my afr 185 heads. if you do not buy a package deal it will be cheaper because you can find used parts for cheap.

The TFS kit will bolt on fine with stock pistons, it is a very good package.

Id do gears next, then subframes...

Rick 91GT · May 12, 2011

The tfs fits with a 2.02 valve due to the rotated intake valve position...

As far as power maybe 20hp over stock, what about your hpipe is that stock

T-5 or AOD? I'm guessing 215rwhp/265rwtq with a 5-speed if those are really your only mods.

For your next mods, it depends on what you want to do with it. If you're doing the street/strip thing, you can't go wrong with UPR suspension, Mickey Thompson tires, and an ATI ProCharger. That's like my magic recipe for fun!

Here are my first two steps with my current Fox Mustang:

1989 Ford Mustang LX - Fox Buildup

1989 Mustang LX Upgraded - 5.0 Mustang & Super Fords Magazine

yes the h-pipe is stock and would you recomend gettin rid of the cats thanks for all the input and im really not looking to go cheap and buy used parts and yes going for more of a street/strip so i think my mind is made up on what to do thanks every one

If your car has to go through emissions, losing the cats is not an option.

92redfox · May 14, 2011

in portland you only go through emissions every 4 years so i would keep the cats and when it comes time put them back on

92redfox · May 14, 2011

as for subframe connectors would you recomend weld on or bolt on

Rick 91GT · May 14, 2011

A offroad pipe will free up some HP and give you a huge increase in the way the car sounds, I prefer X pipes now days but a H-pipe works just fine.

Can you weld? A good full length subframe connector is a good choice from the start to keep the body from twisting, youll feel the difference as soon as you install them. It also gives you a strong lifting/supporting point for a jack and jackstands. Then like Sharad I am partial to the UPR suspension products as well, any suspension upgrade is worthy to a stock set-up.

yeah my freind can weld really good i would pay him to do it
