I searched and didn't find anything on the topic. I was just wondering if anyone here has any experience or know of anyone that that has increased their engine displacement. Or has anyone just done an engine swap? How much are we talking about here?

 

Engine swap is going to be about $10k....thats alot for 20hp....I have a 99 with a 3.4L and I would say the difference is MINOR if noticeable at all...I drove a 02 I was going to get, then an 04 with a power kit and a 99...out of the 3 the 99 was the one I liked the best...My suggestion, drive them, then pick....the 20hp wasnt a big deal to me....it may be to you.

 

I think bang-for-the-buck you'd get a better increase with an SC kit, like the EVOMS kit. Plenty of us here have them.

I think if I popped my motor though, which I'm sure one day will happen, I'd look at replacing my 3.4 with a 3.6, or whatever would fit in.

I've currently got about 67k on my 3.4, SC'd at 60k ... there are people on here with closer to 100k with SC's motors, they seem to last forever.

:-)

What's driving your thinking about a 3.6 ?

 

I think its what gets lots of us...wanting the latest, greatest, fastest, mostest, etc...but look at the performance...the 99-01 is near identical in performance to the 02-04....so the extra .2 cc is not that huge....Will you ever notice a tenth of a second in 0-60 or 1 mph top speed? NO. Here is what most dont understand is that the engine rating per car can vary +/- 5-10%. So the WRONG 3.6 wont have 320 hp...it would have 290....now the RIGHT 3.4 wont have 300 it'll have 330...so in some cases there are 3.4's out there with more power than 3.6's....Yes the AVERAGE 3.6 mas more hp than the average 3.4, but again...its not that serious. All these cars are FAST....period....buy the one you like and enjoy it!!!!

 

I agree with newport. 20 hp is not going to do much for you at all. the 99-01 996 ran like 13.3 on avg, and the 02-04 might run maybe a 13.2 avg. not worth the extra money. but a 3.4, get exhaust, intake, headers, and a chip, and if you want, sport cats for like 5K or so and youll get some decent power. upsolute claims 22 hp and 15 lb/ft alone. add in all the other mods and your doing ok, enough to put u into the high 12s. also, if youre a good driver, that makes it all the better with a 3.4. other than that, a SC is the only way to put on a lot of hp. i personally like the NA engine and love turbos, so the 996 or 997 TT is next for me.

 

Thanks for the info guys. Newport, is that $10K for both parts and labor? What about putting in the GT3 engine? :-) Has that been done? Is there a 3.8L engine? Sorry for all the questions. I'm just trying to get a feel for what's out there. I know there's forced induction, but right now I'm just exploring the N/A options.

 

Damage,
Like everyone is telling you, the difference is not much between the two engines. However, you can do whatever you like if you're willing to pay a premium for it. These engines aren't small block chevy cheap, so the old adage goes, "Speed costs money, how fast do you want to go." If you're talking GT3 engine, you may as well supercharge a 3.4 or 3.6. or step up to a turbo.

 

I think stock 3.6L engine is 10-15k parts only. GT3 engine is like 2x of that I think. No one in the right mind would put a GT3 engine into a Carerra since engine costs more than the car itself. You might as well buy a GT3 to start with.

 

What about a stroker kit?

 

10k is engine only....labor would be another few thousand...although the number 8500 seems to stick out in my head so maybe thats the cost....but I think thats with a core and since your core isnt a 3.6 that wouldnt work....

 

Important issue no one mentioned. You cannot easily replace a <01 engine with a >'02 engine due to the wiring. The early cars had a normal throttle cable and wiring, while the newer cars have CAN wiring and drive by wire throttle. I looked into putting an X51 3.6 or 3.8L into my 1999 and both guys I talked to that had it done had issues AND they spend massive $$$ getting the wiring harness, pedal clusters and dash pod changed. The only guys touting it as a great idea were the few shops that were selling the conversions. Most shops around the country told me point blank it's a bad idea. If you have a new CAN wired car, absolutely go for a 3.8L x51 for about $9500, otherwise put a reman factory crate 3.4L in with the extras like lightweight flywheel, Giac and an exhaust and enjoy the fast reving 325hp!

 

Yes true...All 996 C4's and 2000+ C2's are drive by wire......

 

you can get the 1999 "S" motor... 340HP stock... it's the X51 that was marketed as the carrera power kit... my mechanic said it's readily available for 99 cars...

Just when you say No One, Someone Will.

I believe that car was built before the GT3 was avaliable in the US. There was thread on rennlist about it.
