ok, so maybe I forget the whole blueprint idea. I thought blueprinting would be part and parcel of any re-build, but hey.
Let me expand on my situation. The engine I have has had an oil pressure problem, which I hope to fix before any re-build. Nissan have said that there is bottom end noise already so its only a matter of time before it lets go.
So, I've a couple of options I'm toying with.
1). IF the engine holds out for a while (and if I can fix oil pressure problem (I suspect a bent sump (see other post))) (phew, thats a lot of brackets), then I plan to buy a re-con/2nd hand engine to re-build myself. This way I can drop in a few choice parts over a slow 'learning' re-build as finances allow to give me a strong unit to run circa 300bhp. When the original does let go I have the 'race-ready' engine to swap in. I'd have around 2.5-3k for this. I can then re-build the original again and so on.
2). IF the original engine snaps tomorrow, I'll do a straight swap for a standard engine, simply cos cash levels at the moment will only stretch to around £1500. This then gives me a timeline to re-build the original as a more dreamy-specced engine.
Question is, where to source a re-con unit which someone has looked over already and given the nod as in decent condition, even if it has standard internals. Need one which someone has done a basic strip and checked the basics, re-assembled ready for straight swap. Does this sort of engine exist for approx £1k?
Cheers for all the help, wasn't planning on engine swapping so soon into R ownership, but love the car too much to sell on.
