Right, I'm back and needing some help from any Zetec gurus about how I should spec this engine. daily life has overtaken me for the past few months but Ive actually managed to get in the garage recently and see what Im working with.

The engine I think you are right clarke5700 is an RS 1800 one
It does have Ho on the inlet manifold but it doesn't have a decompression plate.

The exhaust manifold is a cast one but I don't know what its off. I can see the part number 434181-1 and AR 0-41 stamped on it.

Ok, so it either has forged pistons or skimmed ones... Im guessing the car cant run at stock CR even low boost without detonating ?

I am wanting some advice on what bits will work together nicely and heres where Im at so far.

I want a Zetec black top 2 litre engine (what years do these run between?) Theres a tubular ex manifold that I am interested in but is says to fit 00-04 ford focus?
Im guessing it will fit but need to be sure..!

linky to manifold

I know I need a custom inlet manifold

I have some forged pistons and rods sorted (black top)

New oil pump and timing belt kit

Do I need to get the head ported and polish and large valves?

Turbo a Gt30 or similar

I already have the pectel t2

external wastegate

wideband 02

My hp goal is around 400 hp.
.
All advice gratefully appreciated

ps/ Does anyone have any experience of live mapping a T2? I dont want to have to fit megasquirt2 but will if I cant base tune my pectel!
