Definitely a lot of fun to drive. Interesting that it seems to pull better beyond 6,000 rpm than normal. Not sure why that would be.

Maybe after driving it more and getting used to the way the boost hits on higher settings I'll feel the same way. For now, especially in the wet, I like having the options.

Amen. In the wet, a modded 930 is scary AF.

So, with the motor fairly well dialed in, the next project is to add a second oil cooler up front in the center location to help dissipate the heat this motor generates. Currently the car has only the engine mounted cooler and the carrera style cooler in the front passenger fender. The car needs more than that, so today I picked up an EB Motorsports RS style front bumper from Rothsport Racing with opening for a center cooler. This is by far the nicest fiberglass bumper I have ever seen, being formed with both inner and outer molds so the backside is as nicely finished as the front. I expect it to fit well with very little fettling. I have an Elephant center cooler kit and chassis duct ready to go. I’ll post some updates on this as I do the work.

I should probably also note that when the motor was rebuilt, we pulled the tranny (short bell housing 930 4 speed) and inspected it. It showed as a fresh rebuild needing nothing and even had a Quaif torision torque biasing differential. That explains how the car put the power down so well.

At the same time I installed polybronze suspension bushings all around to replace the worn rubber units and confirmed the car has 21 and 27 torsion bars, and that the shocks were in good shape. It now has a very smooth and controlled ride with great transitional response.

I also upgraded to a 23mm master cylinder (with vac assist), rebuilt 993 calipers front and rear and 930 rotors all around (early two piece floating style in front with Rebel Racing center hats). The car now stops hard and has more than enough brake to match the motor.

Your engine should not have a heat issue at all, the single Carrera cooler should be all you need. Is there some hard duty going on like track use or idling in traffic for an hour?

Well, after driving the car for a while in this state of tune, I have to agree with Rarelyl8 and say it doesn't need a second front oil cooler for street driving. So I left the early S valance on it as I prefer the looks of it to the RS bumper.

I've been doing some additional refinements on the car as well. I installed some houndstooth ST style seats, swapped out the tired old turn signal lenses for some new euro ones, cleaned and detailed the engine bay (redid a few electrical connections, refinished fan and fan housing, ext), and installed some LED projector headlights. I think this car is just about done.

Been experimenting with recording video with good sound to capture the experience of driving this car. I think Iím getting close.

I agree. I kept fairly cool even in TX heat. I did have an issue with some kind of blockage while on a drive that caused the motor to overheat. That was expensive. Get that checked out.

On BAT ...oh no. Best of Luck. I think my 914-6 will end up there. Not sure if I can deal with the arm chair experts!
