MFX Posted 10June, 2017 Author Report Share Posted 10June, 2017 Parts for my engine build are slowly trickling in.As I mentioned in this weeks video I am also looking for a 2.7 cylinder which is suitable to be bored and recoated. I need it to replace one I have which is not repairable. Let me know. Link to comment Share on other sites More sharing options...
Peter M Posted 10June, 2017 Report Share Posted 10June, 2017 So Jeff what's your final engine spec going to be? Pistons, bore, cams, compression ration, induction, exhaust, ECM etc. Link to comment Share on other sites More sharing options...
MFX Posted 11June, 2017 Author Report Share Posted 11June, 2017 At this stage I am still trying to pin down the exact engine management I will be using, but the rest should be roughly as follows. The cylinders, if I can find one more, will be bored out from 90mm to 92mm and I will be using the original crank, which will take it out to the same capacity as the original 2.8RSR (a little over 2800cc).The stock rods are getting the heads tapered to save reciprocating weight an the top bushings are going to be redone offset towards the top of the rod, to make the rod slightly longer and also be able to drop from a 22mm pin to an 18mm (also saving reciprocating weight).The pistons are being designed at the moment which will be a much more modern shorter skirt design, with shorter rings, which again saves weight and friction without reliability loss.Compression will be somewhere around 11-11.5:1 as the heads have been twin plugged. The rockers have been repaired and sent off for re-hardening, and cams will be a custom grind to match the rest of the engine specs. It will all be simulated on a computer first so that everything should work together.I have some ITB's which will be running some sort of EFI and I was looking at running a second distributor off of the end of one of the cams, but I am now looking more into using individual coils.Just trying to keep the budget under control is the difficult part, but Neil is really going above and beyond so we will have to see how it all comes together. Unfortunately it is going to take some time, and I have a feeling I will have the rest of the car completely finished and I will start on the 240Z before I get the engine parts all together.

Cheshire Cat Posted 11June, 2017 Report Share Posted 11June, 2017 Have you decided what ECU you are going to use Jeff? Just in case, if you will go the way with the EPM I have one spare for sale. Link to comment Share on other sites More sharing options...

That is all still to be decided. I will let you know when I get to that stage. Link to comment Share on other sites More sharing options...

Mike D'Silva Posted 12June, 2017 Report Share Posted 12June, 2017 Yep, and the Alfa is somewhere under the pile of leaves in back yard....you sure it didn't rust away and what is left "looks" like a pile of leaves?? Link to comment Share on other sites More sharing options...
Jason E Posted 12June, 2017 Report Share Posted 12June, 2017 you sure it didn't rust away and what is left "looks" like a pile of leaves??That's certainly what happened to my old 105........... Link to comment Share on other sites More sharing options...
MFX Posted 12June, 2017 Author Report Share Posted 12June, 2017 I assume there is still a bit of an Alfa under those leaves, but definitely no guarantees. Link to comment Share on other sites More sharing options...
