This is a legal engine, the witness marks are still VERY apparent on the head.

Looking for only around $5,000.
PM me, we'll talk.

it is NOT ITS legal if it as a 944S gearbox installed in it. Still 5k for a logbook race car is not a bad deal.

Good luck!

That's a very good deal. Interested in a trade + cash for an ITC Honda Civic?

Pics, I know several people who would be interested including myself.

Is the rear brake bias a front-to-rear valve or a side-to-side valve? If its a side-to-side how did you install it?

Is this car street-legal (or even close), or will I need a trailer & tow rig?

Its legal in Ct.
I have to take some pics.

Why on a road or track car would you ever want side-to-side brake bias? I've never seen it except on serious off roading vehicles. I could see a slight application on oval racing due to the staggered wheel sizes on the sides.

It was used on the McLaren team's F1 racer a few years ago with a separate brake pedal. It reduced understeer and made the handling of the car alot better.

I'm not sure about the "made handling a lot better", but it did work as a form of traction control. Basically by braking the inside wheel slightly under acceleration, they could get on the gas just a tad bit quicker.

They did also use it under cornering to make the car handle a little better, but my understanding is that this was a relatively minor improvement.

FYI... it was the 1997 McLaren MP4-12 More Info

I see these on dune buggies where they have brakes to help turn them better besides just steering. Think tanks too.

But for road cars where you turn both left and right...i'm wondering how this works where you have to adjust the dial for each time you change directions (if you adjust it so the right sides grab more then what do you do when you make a right turn - understeer into a wall? I can see it on F1 where the epitomy of any ideas are implemented to gain just a 100th or even 1000ndth of a second.

Anyway as exlained it seems to be not a hydraulic bias valve system typical used on racecars but a computer controlled biasing created for cornering.

Its a steering brake, my buggy has one but im not sure how safe something like that would be on a track at high speed.

The bias valve on my car restricts the rear brake circuit in proportion to the front.
