Introducing my Tangerine 73 project

[will hung]

Just incredible.

Great to see my car in Esses, my thanks to John Dilger for making that happen.

In process of planning/purchasing parts for next phase of cars development. Twin plug Mahle Motorsports 3-3.2 conversion, Carillo rods, etc, Zuffenhaus RSR brake package, 1995 915 transmission rebuilt strengthened with gate shift and short gear ratios. Rebel racing suspension refresh/redo. and more

Will post pictures as project gets under way in June.

some pictures of bits and pieces coming together for my Engine/transmission/suspension/brake rebuild and update. pushing to be done for R Gruppe rally in September. Waiting on Mahle 3-3.2 forged pistons for engine to be finished up.

Just when I thought it couldn't get much better…it did.

Xtreme does an impressive cylinder head. They are pretty, can't wait to see how they perform.

Any general/rough numbers on what this kind of work costs? >$10k? . . . >$20k? . . . etc. I'd have hands full just sourcing anything in Beryllium

And how did you come to pick Xtreme, in the 1st place . . . to do all this work? Previous dealings, referral, web-search, etc?

Looks/sounds pretty impressive, too. What kinda HP are you expecting?

Great stuff!

How much HP will she make? Only answer I can give at this point is that I'm looking forward to finding that out myself and hopefully a good bit. As this isn't a stock build only way to know is to run it for a bit and then dyno it. Bruce at Klubsport is doing the work and has built similar engines but none with this collection of parts. He builds a great motor which is why I am having him do my build. The goal for this motor is a street optimized, free revving, torque rich motor with strong bottom end but still feels special once it comes on cam as well as built for long term stability. That being the case Bruce selected a Web Camshaft that makes usable power to 7200rpm. With the custom heads, Mahle forged pistons with valve reliefs cut in, Carrillo rods the motor is one that could spin over 8k but that wouldn't make for a good street motor. Other than the camshaft selection Bruce build a similar motor for his personal race car that his son raced with great success. That motor is a 3.0 that makes 330hp and is shifted at 8200rpm. However, that motor only comes alive once it is on cam and not something that would be practical on the street. I'm guessing my motor should make at least 280 hp (I hope) but could make more? The pistons are a 3.0-3.2 conversion which should add a few HP and ftlbs. The gearbox uses Guard gears with a short ratio spread which should help make the motor feel even stronger than it is. All together in my lightweight car this should make for something that pulls well. I'm just sitting back writing checks and hoping for a result that knocks my socks off.

Why Xtreme? Easy answer is that is what Bruce selected. Klub Sport works with them on many of their engine builds and they have a good relationship. Xtreme has a great reputation for the art of machining the ports to maximize power. This is an art and not a science and they seem to do a great job with it. They did the ports specifically for my 3.2 motor with 7200 rpm Cam so should match up well. If the ported too big then I'd loose all the torque I'm trying to have this motor make at the low end.

Motor will be together and running in the next 2-3 weeks as I need to have it broken in and sorted for a Rally the end of September. Will report more as I know more.

very nice!

i'm a little biased for tangering
