Ok as most of you guys will know, ive been going on about getting my f7r rebuilt for some time now, with cams, headwork, mapping and possibly bottom end balancing; but havent done sod all about it yet.
Ive been doing a LOT of reading up recently about this, while trying to save - but keep spending my money on goodies such as polycarbs and a cage!
The funds will be in place to get the engine totally sorted in october for definate, and im most likely taking it to hillpower for the work to be done, unless anyone wants to give me a good quote!? :wink:
Only thing im wondering....and this question is specifically directed at BenR, stan, 2live etc etc, but is there any point rebuilding a perfectly healthy and fast bottom end? Its on 95k currently, but burns very little oil, holds fantastic oil pressure at any temperature, doesnt run hot at all, even when giving it some good top of the rev range in 5th action. So if it aint broke dont fix it right? Did a 14.1sec 1/4mile at crail on a day with poor grip, but very low ambient air temps!
I do expect to be rebuilding the bottom end at some point (in the next few years when this will be a DEDICATED track car) but is ther any need to spend extra money on rebuilding the bottom end if its fine? I can put this towards some 4 pots and maybe even better coilovers?
The head is needing rebuilt, as its sounding quite tappety these days, even when hot! Most likely worn / sticking tappets! Im getting headwork done on it at the same time (matched manifolds, ported etc) to compliment the cams.
The reason im thinking of holding off with the bottom end build is that if i leave it a couple years i will have more money to spend on it, and get forged and balanced internals, coupled with some lairy cams for the head and throttle boddies!
Suggestions......
