Wish to upgrad motors form 99 C2 to 04 GT3

Recommended Posts

Hi Guys

I am thinking to do a project with my year 1999 Carrera. I knew here who has a complete 2004 GT3 engine, tranmission, wiring.. etc kit for sale. And I wish to have them install on my year 1999 carrera. Would this just fit directly inc. transmission? or the engine size is different as my car is original 3.4L engine? I really wish to upgrade the power of my car and this is a very good chance to do so (the price is fair for those kit). As the kit come complete so If the engine and tranmission fitted with no problem, then it should work, right?

many thanks

it should work if its a complete kit and will convert ur car to egas as well as all the other wireing, engine, tranny etc coomponents.

what u will have in the end is a 45,000$ kit installed on a car that will still get shillacked because the GT3 will have a much more refined, and stiffer chassis because of seam welding as opposed 2 spot welding on the earlier cars.

if u wanna go ahead and solve this as well by rewelding ur pannels or welding in a rollcage, then yes, you will have a GT3 which will have cost u way more than just goin out an buying it.

however, if u do have a connection for these engines..wnna lemme in on it ;)

Barchetta - if you want an honest opinion, you'll waste your time/money doing a GT3 conversion because nobody will want to buy it when you're ready to sell it. No only will you need to change the drivetrain, but also the suspension and braking system to the 350mm calipers, etc. You're talking about a boat-load of time/cost/headache and then you've gotta do the aero kit and wheels (another $10K) if you want it to "look the part." Instead of spending $45K+, why not just dump your 996 for $40K now and put the additional $45K with it and buy a 2004 GT3 for $85K -- there's a nice Speed Yellow car here in the Dallas area (been in the Pano for months) as well as others on Autotrader.com for the $85K-$90K range......once the 997 GT3 is delivered next year, the 996 based car values will plunge. Be patient and you could be driving a real GT3 in a year and protect your resale value -- or you could still be under the hood hemoraging money trying to build a clone.

Just my $.02
