As an example of my parts concern on a recent post I cited the comparison of the new, "upper level" Geba pump which I purchased recently, which exhibits a fair amount of casting artifacts...some of which look like they might interfere with the smooth flow of coolant - which I plan to shave off with my dremel. The pump I'd removed from my engine, on the other hand, is an original Porsche product - which had been installed years ago as a "rebuilt" unit. The bearing on this old pump still feels very solid, and the fit and finish of this pump is very obviously superior to that of the new Geba unit.
Another replacement item on my list is the fuel pump...and I really don't want to end up with a poor quality and/or counterfeit unit, which are apparently ubiquitous these days.
As for keeping things stock, my feeling is that I really would like to know how my car performed as it did originally from the factory...and I will try my best to achieve this. Then again, I've already replaced my throttle cam with the circular unit, as I had on my previous 85.5 (best 30 buck upgrade IMHO), which itself had been chipped...giving a noticeably livelier driving experience - which I'll admit that I enjoyed! So I just might go ahead and chip my '87, but will likely do nothing beyond this to "improve" its performance.
