ever thought about a gt3 motor?

Will it fit in a 993 NB?

This is one of my favorites:

I believe that it subsequently was sold by the owner.

That ship has long since sailed. I funded the business opportunity through other means. No way I'd let it go for that today.

If you're serious I can help point you in the right direction. The 993 NA motor is a GREAT place to start. In some ways better than the turbo version (VRAM version really).

Beyond the fabrication to fit the turbos and intercooler you will need.

New Rods
Welded and flame ring heads
New valves and valve springs
Cams
P&C's
Aux oil cooler

Once you build the internals properly the limiting factor becomes octaine and cylinder head temps. E85 solves both issues.

Mine is fully built to take 700HP. I am REALLY close to doing the E85 conversion to get me there. Just a fuel pump away.

Yes, E85 is key; and with a proper tune one can make big hp with zero detonation.

Also, if it is known ahead of time that you'll be running E85, you can build the engine with a higher compression ratio safely, and its advantages felt throughout the powerband due to its greater mechanical/chemical efficiency.

E85 is fantastic...

Right on point swaybar. I built my Miata track car the same way. It has 11:1 CR and 9 psi of boost. The results were 300hp at the wheels.

I built my 993 motor with E85 in mind. I kept the stock 10.5 CR pistons (same material as turbo), added Arrow H beam rods, flame ring heads, Ti retainer 8k valve springs and cams. I am somewhat limited by head temps now with 100oct. Once the E85 conversion is complete I'll be hovering around 700hp.
