Boxster S simplest power upgrade

[peterpeter]

Hi all

I know there has been a fair amount on this in the past but I'm just wondering was the latest consensus is
To get another 15-20 hp out of a boxster S

Mines a 99 3.2 and have just had the mo30 suspension fitted with some track tyres too
But would ideally like a bit more noise ( that could be switchable or not too loud for goodwood/ Bedford)
and also to get the Ecu done via DMS or something Similar

By expecting whopping power but if I can get another 15-20 for a couple of k I would be happy

Appreciate any input if anyone's been down this route

Thanks

Ps I'm sure I'm going to get the suggestion of driving instruction- but I've been tracking for years and though I've had a
Little break I've been getting back into it .. !!
So target is 265 - 260 hp with combo of exhaust filter Ecu

Cheers

Yes, that is my first Boxster. There will be other links and resources I used linked through my thread too.

As for the exhaust manifolds/headers, just search ebay for "boxster exhaust". You should find loads of mnaifolds for £109,00 + circa £10 delivery. They come with new gaskets. 2.5 and tiptronic should be different to S.

The 996/997 throttle body part number should be there too but to save time, see here http://www.planet-9.com/reviews/boxster-performanc... You need 4 of the shorter screws.

You want the 996 or 997 intake distributer/plenum but for MAF to throttle body intake pipe you will need to make one which my thread should show you.

Many people don't like that exhaust you linked as on it's own it is very loud and booms a bit at 70mph. Pair with manifolds and it's a much nicer sound. I'm not convinced the exhaust box adds a whole lot of power but you might consider just doing the bypass mod or doing a Carnewal mod on the existing box. If you do want that exhaust most sellers sell the same thing. Just look at the pictures, they are all the same. They all bulk buy from alibaba.com and at the right buy level they can personalise/brand the product with whatever they want. You should be able to get it at £219 or cheaper.

For track day car also go for the under drive pulley and shorter drive belt. Email me if you want to do this and I will pass on the details so you can get a 4" cheaper version, ditto for poly gearbox mounts.

thanks so much for this .. its really helpful

Power is really all im after- not worried about having a new back box-
So from what you are saying I think ill go for the manifolds as suggested above then probably a 100 cell cat with the Carnewal mod-

Sound good?

Ill email you about the pulley/ belt

thanks again
