which is more efficent and effective

i was wondering, which would be better for a boxster s.

custom supercharger system (max 200 hp increase, min 120 hp)
or
a gt3 or gt2 engine transplant if possible.

either way im talking 400hp. What parts of the car do you think need beefing up? can the stock transmision (triptronic), power train, chassis handle this power.

all this would be done after 30,000 km.

i know some of you might disagree with tuning the engine, (RC) but i would still like to enquire about the possibility and cost.

Re: which is more efficent and effective

OK,

First, there are going to be a bunch of posts about "you shouldn't do that blah blah blah." And normally I'd be right in there. But SPEAKING HYPOTHETICALLY, if you really want to know which is the better route, supercharger versus engine transplant, I'd say engine transplant. The M96 engine really isn't designed for forced induction (supercharging or turbocharging) and your risk for premature failure would be significant. However, the fundamental differences in the GT3 engine and the M96 engine (dry vs "integrated" sump, etc) are such that the most cost effective engine transplant would probably be one of the 3.8l powerplants, either 355 or 381hp. Finding a tuner to do this for a reasonbale cost and who will stand behind their work and be near where you live are totally separate issues that may or may not be readily solvable.

Now back to reality. From your question, it sounds as if you intend to buy the car, drive it until the warranty is expired, then modify it. Wouldn't it be less risky to lease it now, then turn it back in at 30000km and lease something with more power later? 30000km from now the 997 turbo, GT3, etc should be available. Maybe even a facelifted and more powerful 997 and 997S would be out too. In the long run you would probably risk less in terms of financial loss and engine damage going this route... Anyway, I'm curious to see what the other posters think!

Re: which is more efficent and effective

Why not buy a used 996 turbo instead?

Re: which is more efficent and effective

I agree with mcdelaug - Unless you're really 'into' modding (in which case you wouldn't wait for the warrantee to expire), it's better to sell and buy again.

I'd ask the same question to us AFTER the 30,000 is up - all the options would have probably changed then anyway.

In 2 years im planning on buying another car, hopefully an m5 or better. i dont want to sell this 987 until the 988 comes out. therefore i will definately either supercharge or change the engine.

In dubai, leasing is not an option that is practical.

If you want a mid engine Porsche for the track, the Cayman, with its hard top, may be a better choice than the Boxster S.

Re: which is more efficent and effective

Why not consider something "made in Pfaffenhausen"? getting RUF 3400, 3600 or RK Spyder instead? The Spyder has 420 BHP and kicks serious butt.
Only problem is it's only built in 49 ex. and probably costs a bundle.

If you go for tuning, I wouldn't go for a supercharger, but conventional tuning via ECU, cooling, camshafts, air intake, exhaust, incresing stroke, fuel pump etc etc

Uh, yeah... and the Boxster S is 280hp. My point was that if you are looking for a mid engine Porsche platform to modify for track use the Cayman is probably a better choice than the Boxster because of its hard top and more rigid structure.

As long as we're picking nits, the Cayman is 295hp.

Re: which is more efficent and effective

I think the engine is something like $30kUSD. RC mentioned that RUF has to buy these engines from the same place everyone else does - the dealer. Maybe he will chime in here.

The GT3 motor is around $40000 USD. A 3.8 motor with powerkit from a 997 will be cheaper and still make 381 hp and good torque. If you are talking about tracking the car, I think it's debatable which is a better option. Now above you said that you think a 400 hp boxster would take most anything on the track. Well, yes, but it needs more than a lot of power. You'll need to do some hard research to modify the suspension and get the absolute largest wheels and tires that will fit. These things, along with bigger brakes, will be as important as 400 hp to your lap times.

Re: which is more efficent and effective

Salam Amir,

I SC my 986 Boxster sometimes ago and I started regretting it from the moment I drove off the workshop. Basically the sweet car that I had before the SC was no more. Drivability, reliability, driving enjoyment and most importantly the sweet sound of the engine (Covered by SC whine noise) went out through the window. Worst of all, the engine blew up one month or so after the installation. It was a nightmare and I won't do that mistake again.
My advice to you, keep the car stock if you want maximum enjoyment. However if you still insist on moding your car, I recommend an engine swap because, I learned the hard way, the Boxster's engine is not designed to cope with forced induction

.

I hope this helps
