According to the Poll there are 22 turbo six cylinder Cortina owners who frequent this forum.

That is more turbo Cortinas than I ever expected to be in existence!

If you have one tell us about it so we can all compare notes.

What size turbo?

What cam?

Carby, injection, LPG?

What inlet and exhaust manifolds?

How much power?

What gearbox?

What diff?

Whatever else is good about your setup?

I will start the ball rolling.

Turbo is T66/0.7 comppressor side, P-trim/0.96 single entry turbine (soon to upgrade to Q-trim)

Exhaust manifold is 6 into 1 merge collector type by 6boost

Inlet manifold is custom log plenum and 6" long straight bellmouthed runners with front mounted XF falcon throttle body

Intercooler is Garrett bar and plate 600x300x96mm with custom end tanks

Cam is a sure cam 264 duration 0.550" lift turbo billet cam with rollmaster timing chain, solid lifters, cromoly pushrods and yella terra rolla rockers

Head is alloy ported and o-ringed

Engine uses ACL 27.9cc dished pistons and shot peened std conrods (upgrading to BA falcon spec H-beam rods and custom piston later in the ryear)

Block is standard grout filled to bottom of water jackets

Romac harmonic balancer

Exhaust is 4" stainless dump pipe with no mufflers ending under drivers seat

Gearbox is a modified C4

Diff is full spool 9" with 35 spline axles

Engine has made 582 rwhp on 21 psi so far.

Best track result is a 9.58 @ 139 mph on slicks.

[MarkZE]

[Admin]

I think those 19 people could be the same 19 people in the poll with the v8 big mutha hanging through the bonnet.

[TE_JET]

Sounds good mate. MIght have some go. The microtech goes well in the corty's. I run that type too. Try a diff ratio of 3.5 to start, the go down as you make more power, it will be a quick car, thats for sure

[MarkZE]

TE351.  That setup sounds like it has all the right bits.

I would stick with the 2.92 or 3.23 ratio at the lowest.

3.5 is too low unless you can rev the engine to 6000rpm or have very tall tyres.
