Turbo lag,
1, The head will be ported and the plenum chamber matched to the head but with standard valves, BD14 inlet cam standerd exhaust.
2, The block will be rebored to +50 and have Mahle pistons fitted, I considerd Cosworth pistons but was told they was very noisy and about £200 more.
I have been told to use standard head bolts but Iam not sure if this is best.
I will be using a windage tray and a Group A sump, ARP big end bolts.
3, My head gasket was going to be a thick Cometic gasket but Iam not sur now, maybe I should use a Mountune WRC instead?
4, All the other gaskets on the engine will be Cometic as well ( I have not heard anything bad about them yet )
5, Bosh GroupA fuel pump and will be using A Group A oil pump as well.
6, Injectors will be Xo39's if I can find some or Greys if I can't
7, Turbo will be my T34 or a T34 wih Maram shaft so I can run Anti Lag as well.
8. RS 500 Radtec intercooler.
9, when all run in it will be live mapped.
the way i see it - you pays ya money and takes ya chance - some get it right some have continual problems !!
good luck !!
