The OP says he's a golfer, that might explain it.

You won't get much HP increase with exhaust and IPD/TB total cost estimated $2,000+ maybe 20 - 25 HP

There is no replacement for Displacement!

Thanks for searching!

I've heard that porsche valve stem covers will add 5hp straight bolt on!

So not even a different cam grind would help the
power ?

Cubic dollars can sometimes replace more displacement! Of course cubic dollars plus more displacement is always the best!

So That's a No on running different cams..?

Yeah, what he said!

I imagine a custom cam grind, some porting (particularly on the exhaust side) larger valves, bigger injectors, more air, hotter spark, higher rev-limit (from balancing and gusseting) would net you some hp.

Is that what you're thinking? Lots of $$ ?

MUCH easier (and cheaper) to dump a 3.4 from a 996 on it.

I was perusing the FVD site they have a set of cams with a different grind for a mere $2200 ish dollars.

flmont · 02-12-2021, 08:51 AM

Well ..Yes ,.If I knew the answer I would not have had to ask..

Sorry, I wasn't trying to be a d*ck, I honestly thought you were joking. There isn't much of a trend to do such projects with these motors. You're not gonna find a stroker kit for the m96, and there are not any shops that I'm aware of that specialize in custom modifications like that for these motors. Most aftermarket modifications you will find detailed on this site fall into 2 groups - small projects that will sometimes require custom tunes (UDP, new intake, new exhaust) and big ones (upgrade to 3.4 from 996, complete motor overhaul from flat F6I or LN including bore out and sleeving). Most DIY projects are about optimizing the current setup for durability and handling (oil coolers, 3rd radiator, aftermarket suspension) There are a few guys who have done FI applications, but there is only 1 kit that I'm aware of still in production and I personally think it's shady at best. Otherwise you'll have to custom a setup, which is difficult because of the specifics of the stock setup and is probably done best with a complete overhaul of the motors internals. A good example of that is bisimotors.

I guess the bottom line is that the H6 m96/97 family is not really a motor that many tinker with. It is what it is. It may seem like a puny power plant, but I think that most everyone will agree that it is well matched to the car overall and if you learn how to drive it properly (keeping it in max powerband, heel toe shifting, proper cornering techniques) you can definitely make a passenger **************** their pants on demand. It won't beat a v8 off the line but you'll have fun passing them on the turns.

Yup;
ditto all of this.

flmont · 02-12-2021, 03:23 PM

Oh its ok..I had a 82 3.0 that you could do a 964 Cam grind that was popular. So I thought maybe it would be helpful here..But, I should know if it was beneficial it would have already been discussed many times over !! LOL..Thanks for the info , Frank

Not until you get past 3,000 Rpm, and you will be much slower to 3,000!

Yeah I just realized this thread was started a couple month's after I got home from Jake Raby's 1st M96 engine rebuild class where I learned the best way to add displacement resulting in greater torque throughout the rev range!_HDR1613347734.jpg[/img]
