eNGINE REBUILD

[james ashby]

is it that easy!! In answer to Bones, i am unsure of which way to go - rebuild for piece of mind, but alot more expense. or chance a second hand engine. I was only tempted by this because my gearbox has problems as well, and this could solve alot very quickly.

On the other point, why are early heads good on a 204 bhp engine?
I take it you mean early sc heads 188bhp.

Earlier heads have larger ports. There is another way of looking at the two engine option, you could take the chance on the engine and gearbox being serviceable but if you are spending bucket loads of money which you if you get into this to produce a 240-250 bhp engine you will then use new quality parts anything else is a waste of time, by all means buy the other engine and gearbox strip them and see what you have but build the engine you want with the best parts you can afford and then rebuild the second engine and gearbox and sell them. A lot of the cost depends on how much you can do for yourself.

£3k for a crashed engine you can't say is up to scratch soon turns into 4 grand if you are paying someone to do the transplant. And then what happens if it's not all it's cracked up to be. Have to say I would spend the money building my own lump up, as Richard says you have most of the dear stuff already. Rebuild your engine as a 3.2, bolt on your carbs and early exhaust, and in that light shell it will be a giant killer.

you mentioned that you racing places said stay standard, dont be surprised, an SC or earlier car as yours with an SC engine in terms outright speed can benefit much more from tuning the suspension, brakes and weight loss, rather than spending £££ on engine tuning to add more power. If you put the more powerful engine in first, the brakes suspension etc will need doing anyway to keep pace. I think its important to keep your Porsche balanced in all performance aspects.

IMHO if you want a good handling 911 for road and occaisional track use then start with the suspension etc and see if you then need more power. If outright acceleration is needed then consider selling up and buy an early turbo car, £5k plus for SC engine modifications giving 250/260 brake is really expensive power and needs another £2-£3k of suspension mods etc to keep pace in early cars

Bruce,

I tend to agree with you but ther is a good argument that once you get the weight down in an early shell, you don't need to do much at all to the suspension/brakes. I have a friend with a circa 975kg 2.8RS with nothing but shocks, brake pads and simple anti roll bars changed from std. It makes 265hp and is a great little track car. The lighter you go, the more you can leave std. If you already have ARBs and good shocks, then track pads are all you need - sure, you can do a lot more but you don't have to.

Unfortunately, its the fat pig 3.2s and to a slightly lesser extent SCs that need bigger brakes etc for serious track work. The early bodied cars seem to survive pretty well close to std IMHO.
