I am a new member, heve been browsing this website alot in the past year. Many exciting projects being built and developed.
I have been a Ford guy for ever, building a 1968 XL with a 514 cubic inch race engine, nice to scare the neighborhood kids once in a while. Also built a 1970 Porsche 911 with a 3.4 engine, quite fast 12.48 sec at 118 mph in the quarter mile.
My latest project is a 1987 escort with a 1.9 engine.
I have purchesed an RS turbo exhaust manifold, and a stage 3 T3 turbo.
.48 exh housing and a 55 trim compressor.
The connecting rods are Cosworth Zetec parts - used for Focus zetec turbo rally car I think. They are 5.427" long, have standard Zetec rod journal diameter. The rods have a 22mm diameter pin bushing.
The early Ford 1.9 crankshaft has larger rod journals (1.885") than the 1988+ crank (1.7283"). The stroke of the 1.9 crankshaft is 3.46". To use the Cosworth rods I will offset grind the 1.9 crankshaft. This will bring the stroke to 3.50" and the correct journal size.
Custom pistons will be purchased. 3.23" (82mm) bore is standard.
Most likely I will bore to 3.25" (82.5mm) The pin height of the custom piston is an easy calculation. Block deck height is 8.378".
CH = Block Deck - (Rod Length + 1/2 Stroke)
CH = 8.378" - (5.427" + 1.75")
CH = 1.201" ( for piston even with top of the block)
I will use a CH of 1.18" ( alot of Honda pistons are 1.18")
