Making sure the big end tunnels are round and the correct size so you get the proper "crush" required on the bearing shells to prevent them spinning.
Most used engines have egg shaped tunnels, knocking the bolts out/in again stresses the rods changing the roundness of the holes as the bolts...
There are 3 coils inside the CPS most times when you run a standalone you only utilise 2 of them, the 3rd unsed coil is still generating a voltage and this can confuse the issue so you remove it, If the cam tensioner sping is new that's as tight as it needs to be.
2mm is 80 thou not 8
It catches up eventually no matter how good you think you are....
I've probably driven more miles @ over 100mph than most of the young guys here have done in their entire driving careers to date..
It caught up with me and I paid the price.
Check out the Z Car thread if you don’t...
Knocking the old ones out and pressing the fresh ones in distorts the big end slightly and considering the youngest 7M rods are now at least 20 years old they're probably overdue for resizing anyway.
If the bearings are ok you can close the airgap down to 2 thou that will give it the best output possible, also remove any unused coils if you're using a standalone as they do interfere at high rpm.
Congrats now FFS get an aircleaner on it so it doesn't suck in crap and we have to go through all this again!! ;)
(hope you're going to run a vacc catch can instead of that little filter on the cam cover)
Yes it is but modern TVS Blowers as a good deal more efficient, while cruising there is minimal "loss" as it's in bypass mode and not compressing, I just think it's too big and will need to be turned too slowly to keep boost managable.
Been saying much the same thing for years now but there...
It's NOT just the Mk4 guys over there that can be harsh ;)
Having said that it seems to be getting better so there is hope, welcome to SM and get some pics up of the car!
