Some more details would be good as I was confused and I think others would be as to what you are actually doing or wanting to do with the engine.

I was.

And blow through doesn't sound like a recipe for a great outcome to me...go modern.

Right sorry bout that I got a std pinto engine 205 block (n/a) I'm gonna turbo it but go with blow through but with the std internals I could only run like 8psi so I wanna cosworth the bottom end, pistons conrods etc to lower the comp and In turn make it a lot stronger so I could run higher boost but I have no idea what the std cosworth conrod length is

Would it not be easier just to fit different pistons to your std pinto to lower the compression seeing that you are only going to run low boost?

The plan is to run 1.5 bar, I have the fuel regulater to give a 1:1 ratio when on boost and an uprated fuel pump and a carb designed for blow through

Burton power list all the rod lengths in there cataloge or online.

Be warned the pinto crank will be a weak point.

Pinto crank is not that bad. 400bhp+ is possible.

I am doing this at the mo

Pinto 205 block
Pinto crank / lightened balanced knife edged
Cozzy rods pistons
Squirt jets ( I will dry sump it in time )
Freshen up ie shells and seals
Head freshened up to
And cam plus springs
Fettle plus exhaust port opening up a bit
Efi inlet with cozzy plenum
( will run efi for now but will end up cozzy management)
Sx200 ex manifold
T3

And a few other bits if I can get them cheap lol

This will be my daily 3dr Sierra so when on cozzy efi I will only run Around
1 bar 1.2 max

As I need it to last

The drive to work need never be boring lol


There is a thread on turbo sport ref" cozzy rods and stuff
