Hello

I own a 986 S with 260bhp. The 987 3.2 S has the same engine with 280bhp. I believe it has a revised air intake. I saw a picture of the underside and I think it has tubular exhaust manifolds. I guess it has a different map too.

Does anyone know if I can 'fit' this to my 986?

As for as I know everything has been updated in the 987. Engine, drivetrain, gearbox - the lot. Again - as far as I know - there is no possibility of fitting 987 systems to a 986 and getting a power hike.

If you want to upgrade your Boxster 986S go check out what the independents are doing. Superchargers (9M) etc. Ruf used to fit a 996 engine into the 986 - that went well.

I expect, however, you would be far better off chopping your car in for a second hand pre-depreciated 987S in terms of bang for buck.

Having said this - I test drove a 987S and, whilst it is without doubt a better car than the 986S, it did NOT seem massively more powerful (despite 20bhp extra). The 295bhp 987S (MY07) may represent a more noticeable upgrade...I haven't test driven one yet.

OK

As far as I know the basic engine on the 3.2 987S is basically the same as the 986S however it has 20 extra horsepower. Reading the literature I found reference to a higher capacity induction system. Also looking at some photo's of the underside I noticed a more purposeful looking tubular manifold.

Therefore I got to thinking if I could bolt on the new airbox and exhaust from a 987 I would end up with a 20bhp power increase.

I believe the 987 is slightly heavier than the 986 and therefore only slightly faster with the extra power.

You might want to try www.ppbb.com for a admittdely US-centric Boxster community. There are some very enthusiastic posters on there and someone will surely know what can be done.

I have not heard many reports of 'incremental' improvements (ie. from one generation to the next) but there are more and more reports of quantum-leap style enhancements from superchargers and the abovementioned 3.4 (911) engine transplants.

Good luck with your search for more power.

crazy talk, sell one and buy the other will be cheaper than doing the conversion properly
