any die hard V6 owners on here?

That's more than the difference between HP of the 99+ and the 94-98?? IIRC, the 94-98 rated something around 160-165 HP? The newer ones are rated around

190HP for a difference of around 25-30HP. Where are all those extra ponies coming from? -J

The 94-98 were rated at 150 and the 99+ at 190. It's similar for the GT, the '96-'98 were rated at 215-225 for the '98 and the 99+ at 260. But putting the 99+ heads on the earlier 4.6 will result in around 275 horses due to the compression ratio being higher after the swap.

Interesting! How do I do this? When my mechanic did the engine swap, he checked into using a 99 or newer v6 but told me it would be a lot more work putting it in, way more stuff needed to be changed than with the

98 v6 that is in their now.

Is it just the heads? I remember something about a return fuel line as well from his list of changes needed to accomodate a 99+ engine.

The 94-95 V6 is rated at 145HP. The 98 engine is rated at 155HP. I have dyno data from the 98 engine in my 95 Coupe on my website. I believe as of 99, HP got bumped to 190 or slightly higher. Last year I did 18.2 on the 1/4 mile with a 95 V6 and standard clutch. This year, under similar circumstances, I did 17.018 with a 98 V6 and a Spec Stage 1 clutch on an otherwise unchanged car...

I ran a 15.404 last month at Infineon in my 2002 Special Edition Miata, with Jackson Racing 6 psi S/C kit, last month just messin' around. Stock clutch, just the "standard" JRSC 990-280 kit. Maybe if I had some race gas in it and wasn't so into ECU timing retard... Maybe if I lost 30 lbs...

Dana P.S. One advantage of "chick" cars - chicks seem more comfortable talking to the male drivers of said cars. I'm a Ford-head, too, don't get your drawers in a bunch.

If the later heads just bolt in, then the rest of the trim doesn't change. I've never tried the said swap myself and, for glaringly obvious reasons, won't be.

There's a pretty good article here:

Thanks! Looks like to much for me to do. I got lost repeatedly reading the article. Interesting reading though. Explains why my mechanic did not want to use a 99 engine when swapping out my 95. To much extra stuff to make work. With extra things that can go wrong and skyrocket the price of the swap...

thank you that's the one I was going to post when I got back on line ....

its the heads , intake , fuel rails and a few other parts ..off 99+ and the headers block and everything else form a 94-98

94-95 ... 145 hp 96-98 ....150 hp 99+ .........190hp

these are fords numbers.......

its about a 600 plus labor mod but well worth it if you can get it done right ....

you might want to check out...>

I'm strarting to look into re-doing the top end on my 96 V6 - Morana Racing have some nice ported V6 heads and intakes that should add some power - that along with some roller rockers and a ported throttle body...

Anyone ever used parts from Morana - impressions?

Thanks Keith

do the split port its cheaper and more HP
