I know a chap who has just fitted a twin-turbo setup to a Boxster, apparently it's extremely entertaining as it's brilliant even with the standard chassis and transmission.

Suggestion

Best to get a 2.5 with a blown engine or high miles which you should pick up for say under £15k (LHD) then rip the 2.5 out & throw it away and replace according to budget with a 996 3.4, 3.6, GT3 engine.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

9 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 2Original post

I know Gemballa were prompt with their biturbo response to the initial release of the Boxster. Whilst undoubtedly effective at despatching a Boxster S, or even naturally aspirated 996's, it is also unlikely to be cheap. www.gemballa.com Take a look. If you e-mail Germany you may even get a response from the man himself (i e-mailed about some split rims for my 993 C4S and got a reply from Uwe Gemballa!!!). If you do go down this route i'll look forward to seeing your Boxster Biturbo at a future Virginia Water meet. VS

POST 3Original post

The standard 2.5 lump is not very responsive to conventional tuning and its not a very strong unit anyway. Best to get a 2.5 with a blown engine or high miles which you should pick up for say under £15k (LHD) then rip the 2.5 out & throw it away and replace according to budget with a 996 3.4, 3.6, GT3 engine. You could get one of them shoved in an S gearbox and decnt suspension & brakes for under £30k and if you budget on a few bits under £25K is possible- even in the case of the GT3 lump. I know coz ive driven 3.4 & 3.6 Boxters & a GT3 Box is currently in development. And although i'm not the bigest box fan its easy to get 380bhp out of the GT3 lump and in a box hmm that would be a very very interesting ve-hick-cool. If you want to know more and you are serious about this drop me an e-mail & I'll put you in touch with the man to talk to.

POST 4Original post

Buy a 964 RS...I am not biased cus I have a 993 RS!! (BTW this is not supposed to be a flame or such like, but doubtful whether you could get a 993 RS for less than 30K..a 964 RS starts to look good value at 26k+??)

POST 5Original post

Fit a 3.2 boxster engine .Ninemeister is advertising 11 on his site upto £5k

POST 6Original post

If you are willing to take a bit of a risk you could look around for for a Ruf 3400S. This is a 993 engine in a Boxster 2.5 basically. The job will have been done by professionals and there is no reason why the resulting car shouldn't be reliable. In these very pages we have discussed such options before and even seen one for sale (can't remember where) at about 30K if I recall. Remember that such a car is very, very rare and is unlikely to be resaleable easily. Like you, any subsequent buyer will be taking a risk and will expect serious depreciation to have happened! So you'll get oodles of grunt, more expensive maintenance and disastrous depreciation. Errr...have you considered a TVR?

POST 7 / ORIGINAL POSTEROriginal post

thanks guys, looks like its a better investment to buy an S, or wait for am old 993 or the new nissan 350z cheers

POST 8Original post

My thoughts on making a fast boxster: 1. Buy super cheap 2.5 2. Throw away aircon, sat nav, electric anything; aim to reduce weight to absolute minimum 3. Fit 3.2 S engine and box 4. Sell 2.5 to recover cost of conversion 5. Tune 3.2 engine to 290bhp with cats, cms, ecu reprogram & sports silencers 6. Fit 996 brakes 7. Fit pair of fixed back kevlar recaro seats & schroth harnesses 8. Paint it Maritime blue 9. Fit Boxster RS badge on the rear Got the engine, got the brakes, got the bin (for the old parts), got the paint, got the badge, got the knowledge, got the time. Anyone got a trousered 2.5 going cheap? >> Edited by ninemeister on Friday 21st February 15:44

POST 9 / ORIGINAL POSTEROriginal post

How feasible is it to buy an old 2.5 or 2.7 boxter and 'tune it' to achieve greater than S performance? I can not really afford 30k for a 2nd hand S but found the 2.7 -well limp. I have a lovely 20v Turbo fiat coupe at the moment which quite frankly eats most boxters for breakfast and i want something with even better performance. Please dont make me buy a TVR as im sure it will drive me mad. feasible?
