NEEDALT1-

First off, don't buy the first good looking Fbody you come across. If you do that you may find yourself hating it as much as your stang. It's just as easy to buy an abused Fbody that will take a dump on you as it is a mustang.

Now on to the opinion part. Get a 95. There is some info out there that suggests that 93's with speed density may be a little quicker, but the 95's come with some really handy features-

1)Vented optispark(distributor)- the optisparks on 95+ Fbodys are more durable because they aren't as susceptible to moisture getting in there and damaging them. You DO NOT want to replace an opti.

2)Reprogrammable PCM- You don't have to burn any chips like you do on the 93's. You can buy a computer program and tune the computer yourself if you like, and if you aren't that adventurous mail order tunes are available for $99+ core charge.

3)Single catalytic converter- Single cat style headers make more power than the dual catalytic converter style.

4)OBDI computer- Less emmissions requirements to worry about. Plus tuning for OBDI cars is less expensive than tuning for OBDII(OBDII starts in 96)

but on 96 and newer cars you can pass emissions even if you HCs and COs are through the roof, they dont run them on the Constant volume analyzer, here in indiana anyway.

 

I think this part should read...you WILL replace the opti. Its just a matter of when. Its not like they will last forever. Its not like any parts last forever.

 

Yea what he said

But generally with a vented opti it will(or at least should) last a little longer.

Wait how do you do thisive never heard of it before. How much power do you gain are there any negatives to doing this.

 

with a adjustable fuel pressure regulator. as for power increase im not sure how much.

 

weren't the 96's rated at 285hp compared to 275hp in the 95 due to them having dual cats, correct me if im wrong.

i own a 95 A4, i took my cat out and put in a flowmaster 80 series, do you think i would have more hp now with this set up than a 96.

 

On www.ws6.com I believe that they dynoed 16 rwhp by messing around with the fuel pressure, but like I said our cars with MAF's adjust the pulsewidth accordingly after running the altered fuel pressure for a while whereas the speed density setups do not adjust at all....

 

I could be wrong, but I think dyno numbers are almost identical for single cat and dual cat cars. I wouldn't bank on a car with a dual catalytic converter setup being more powerful stock.
