I just purchased this:



as a track car. It weighs in at 1400 lbs without an interior, engine or transmission. I plan on going both autocrossing and full road course racing with it. I'm considering a 3.2 or 3.6 engine for it (I already have a 915 transmission) but would like to get around 350 hp so that I have a good enough power/weight ratio to keep me ahead on the two front straights at our local track. Should I be looking at the 3.3 turbo instead? I like the thought of staying non turbo just for the throttle response and simplicity but I wonder if it is too expensive or difficult to achieve with either the 3.2 or 3.6 engines. Any suggestions?

Some people do chevy v8 which can get up to 550 hp. This is not the approach I would take but to each their own I guess. How much are you looking to spend on it? A 3.6 litre 993 or 996 engine would be a pretty cool option but i am sure there would be ALOT of work involved making it "bolt up", may not even be possible. A 3.3 turbo engine would be nice too.

I think a 3.6 in that little 914 would be a BLAST. Rick DeMan had one at last year's Rennlist Reunion configured as a 914/6 . . . fast car. I'm not sure how far away you are from New York, but you may want to check with Deman Motorsport in Nyack @ 845 727-3070 or <a href="http://www.Demanmotorsport.com." target="_blank">www.Demanmotorsport.com.</a>

Good luck with your project. It will be awesome.

Uh oh. Just realized that you're in Alberta.

Try to talk with DeMan anyway, he may have some real valuable tips for you. Take notes, he is a Porsche guru.

Closer to you, is Steve Weiner at Rennsport in Oregon. Great guy, great shop. Steve is a regular contributor to this board and he can sell you everything you need to stick a 3.6L in that little rocket ship you're building.

I think I saw the Deman 914 in Excellence. Love the looks of the car and from the description it must be fast. I'll definately talk to them and Rennsport. Thanks.

Yes, that was Rick's car in Excellence magazine last year. Nice article.

Huntley Racing

We have done several 914/6 conversions with 3.6 ltr motors. We like the combination since with some Huntley magic in the motor we can make 300-330 HP at the wheels. The trottle responce is much superior to a turbo. We onlt go with a turbo motor is the HP goal is over 400 HP at the wheels. Of course we could build you a 4.2 ltr motor that makes 400 HP at the wheels to or a turbo version that makes over 1000 HP! <img src="graemlins/jumper.gif" border="0" alt="[jumper]" />

If you are really going to road race it check out the rules of the clubs you plan to race with. SCCA limits 914s to 3.0 in GT2, the only real national class for a 914/6. PCA has 2.8 & 3.4L limits in GT4 & GT3. You need to dump $10-12k in parts and machine work plus $5k to have someone build it if you can't to build a competetive 911 motor. You may want to race with POC or a vintage group. It all depends who is most active in your area. It will take serious money to build a competetive turbo car, most of them are $100,000 3.8L machines. SCCA road racing does not have a national class for turbo cars.

Bottom line, get the rule books for the clubs you want to race with and build a car to those specs. You don't want to build a killer 3.0 motor and find out you are allowed to have a 3.4 in the class you end up in. And you don't want to cut out you front suspension pan and find out that keeps you from racing with the club that is most active in your region.

PS as you approach the 100HP / liter mark in a normally aspirated engine you will need $2-3k worth of gears to keep it in the powerband.

Yea, a devek powered V8 with 600 hp

Now that is fun!

Hmmmm a 1000 HP 4.2 ltr twin turbo flat six from Huntley Racing would rearainge your hair a bit! Of course I would recomend a padle shift sequential gearbox to free up a hand to hold onto your goods while your at it!

Y'know, I happen to have a new-in-the-crate GT3 Supercup motor sitting in the shop hmmm....

RX-7 13B Twin-Turbo !!! Will get you 500hp for 150lbs less than ANY Porsche engine! And it'll rev to 9000rpm easily too!

Danno,

I actually own an 87 RX7 Turbo with a 13B that I was making into my original track car. I was aiming for 400 rwhp in that car. I have a haltech E6K, T04E 60-1 P-Trim 1.00 A/R Turbo, OS Geiken 4 puck dual mass clutch and flywheel, 2 550 cc primary injectors and 2 1600 cc secondaries, Walbro Fuel pump, and the list goes on. The downside to this set-up is that while the rotary engine makes decent power it doesn't have as much torque. I guess a 20B (3 Rotor) would have more torque but would cost nearly as much as a 3.6 engine. Also I would have to plumb in a radiator. Finally, I'm also a little concerned as to the fragility of the rotary engine. I'm in an RX7 club and know first hand what can go wrong with these engines. Does anyone know of a website or of someone who has actually put a rotary in a 914?
