there you go. sweet!

 

Took another turn for the worse today. Spoke to Dougherty racing - very reputable and knowledgeable shop.

He indicated several issues in going with a new motor that may be insurmountable:

Wiring is completely different type - cannot be rigged & and a complete wiring harness will not mate up with the rest of the car.

3.4L has a 2 solenoid varicam vs any 2000&up has 4 solenoids. Over 3500rpm the car may not run right or at all!

Dash pod is different.

No easy fix for the e-gas issue, even with programming.

Unless I can find a cheap rollover, it doesn't make sense to embark on a project with no clear solution to a machine technically more complicate than the first moon rocket. I have yet to speak with anyone (who's not making a profit from it) that says it can/has been done successfully.

Guess I have to be happy with "only" 296-315hp in a 3.4L.

 

guess that's the 1999 model year hiccup marc told me about. well, at least the 3.4 motor is relatively cheap.

 

you should talk to JimB ever on rennlist. he replaced his 3.4L with an x51 3.6L. he said it wasn't too big of a deal.

if you do all the mods for a NA996 you would get 330~335HP. i did

-or- get new pistons/rods/sleeves and bump up the displacement to 3.8L

-or- just get a supercharger

you never did mention what kind of RACING you do/will be doing. you don't want to mod yourself out of a class.

 

Jim's car must have been a C4 - they had egas. I still have my doubts, but I'd love to be proven wrong before I order a 3.4L.

Who sells pistons and heads for a 3.4L? I called ANdial and a bunch others with no luck.

I autox 20 days and do about 6-8 track days a year. Class doesn't matter because the only guys I compete against are running modified cars, so a bump up wouldn't afffect me.

 

i think he has a c2. in his race blog, he states that he has a late '99 996 so thay may mean an early 2000. in another thread he did say the at retrofitting or bypassing egas isn't that hard.

send a PM to sharkster. he mentioned the conversion to me without going into details. check with the german-european tuners cargraphic/fvd/ruf.

if class doesn't matter then supercharge it

 

Again, call Ruf in Dallas and see if its possible.....They do this kinda stuff all the time....if they say its possible, then you know it can be done.....then ask them how they get around the wiring harness issue and e-gas....I bet they would be pretty helpful for information.

 

The e-gas is a simple issue to resolve, the simplest actually. The wiring on non c4 99 model years is a totally different issue. I would only reccommend it for a track only car. The Variocam wiring is a large part of the problem, as well as some of the security systems in the car. Can it be done, simple answer is yes, but there are issues that make it a more than simple swap. But hey, every job is possible it is just a matter of whether or not it is cost effective. Marc

 

What about 01 C2's? Would the swap be less complicated? 3.6? 3.8?

 

I have a 99 C4, with e-gas so thats not an issue, but what about this variocam thing? Would I have a problem with a 3.8L swap? Is the 3.6L more of a plug and play?

 

Just spoke with RUF and Sharkey and they confirmed the 3.8L conversion is an issue due to the different wiring type and variocam/ram issues. The 3.6L in an early 996 is not feasable as well, except in a C4. Unless I can find a complete rollover I don't think it's going to be worth the trouble.

This would make an interesting article in Excellence if someone could come up with a kit to get a 3.6L x51 in an early 996.

 

Newport-Your car is much closer to being plug and play, but it is still not a simple swap by any means. I have not attempted a 3.8, but would wager that the 3.6 is going to be the only semi cost effective swap.
Racerjsz-I believe that the e-gas was introduced mid year in 99 with the c4 introduction. I have been under the impression that some later production c2's could have e-gas as well. So that might make your plight a bit easier. As I have said, the swap is still possible in your car, just not very cost effective from a labor side. Whats that saying "How do you get a small fortune from racing cars? Start with a large fortune!"

 

ah sorry about that. i guess i heard sharky incorrectly.

there's this guy, mike lansky who has a boxster GTS racer. here's his engine specs:"
Engine: 0 hour 3.4 996 motor 100mmx 78mm Mahle Pistons w/ custom steel sleeves 11.3.1 compression Total Seal rings Porsche Motorsports sump and scavenge 996TT oil pump 996 crank and rods balanced Cleulite Rod Bearings Cyclo Main bearings Elgin custom ground cams 272 deg 406 w/ lifters Elgin springs, caps and keepers Sodium valves 3 angle valve job 996 intake manifold New power steering pump Bosche 996 injectors Bosche 4 bar fuel pressure regulator MODE Motec M800 engine management"

what i am getting at is it can be done but you gotta talk to the right people, motorsports people. good luck.

 

just wondering, after all the mods to the engine, what kind of performance do you get ??? 0 to 60 times go from what to what???

I'm still thinking of changing out the rear panels (maybe even turbo fenders; I love the look) to make it wider and then starting on the engine.

 

Robert,
Prototec in Pompano has a twin turbo stage 2 kit for your car for about $25k. It supposedly produces more hp than the evo or tpc supercharger (it should for twice the price). Give them a call.
