Hey guys i am the other guy in the project, we are not going to run the ass out of the motor as yes we want a little reliability and there is no way we will get that with 14psi for sure , as it is the fuel has been sorted with a 4-6psi pump, the head is going to be decomp with a A14 head and thick gasket, L20 valves i am tryin to find out if they will fit or we will just get double's for it, and there is no way we are converting it to lpg no matter what the gains may be, as for the comment of the waste of a good datto , we dont think so as it will be a race car so if thats a waste to you but a gain for us sorry... if we blow it up as stated there are A14 flattop pistons to go in it so the cost is cheap as they dont have to be made oversized just take the block out to suit...already checked that out, as for the diff it will be welded with torsion bars and a brace put in for good measure which is all going to be made by ourselves, if it blows there will be a bluebird diff for replace, by our calcs as we have both owned datto's there will be a good chance the car will survive the batterin it is going to get as it wont be strangled throttle open gettin off the line at the drags , launch is going to be a key to keeping the car in one piece and not detonating either the motor or the rest of the drive line....... feel free to reply with info but don't try burst our bubble with no you cant do it , thats no help to us try recommending something a little better that we have planned already.... CHEEERS

Thanks for all the positive and negative and ridiculassss comments(20psi?????) But the car in question is rooted let alone getting it fixed for roadworthy..... both floor pans will be replaced and the whole arse end above the fuel tank including the tail light area and the sides and doors and......etc so it really is just a fix up and race and hope it doesn't blow up to soon, but got a spare auto motor and auto plus another spare engine so I'm just trying to get info on how the set up of the turbo should be and I have a few ideas now....keep them coming

as per comments...

I want to go blow through but unsure the weber sealing ability, plus i would have to get a high pressure fuel pump and reg to equal the boost.....so I've been told.

1. never heard of flame back so thanks for the info.

2. flat changes mostly..... but see what happens.

3.Where using a plumb back so it's all good.

Thanks bloke.

G/day people, New members here. My house mate and I were given a '73 1200 coupe and where making it into a drag car. We got the motor to run and it has a average of 110psi to 130psi compression in the cylinders.

Now this has cost us only $60 bucks for the turbo and everything else was given to us, were doing it on a budget of as little as possible.

What we have also is a CT20 turbo of a diesel hilux (30'000klm old) and a 40mm side draught weber of a 2L escort and a 1200 manifold to suit the weber. Where having it as a draw through set up so no intercooler and I'm making the manifold for the turbo exhaust side etc.

The motor will be left stock except for a bigger radiator and a couple of other things.

What sort of boost level do you think would could go? We are not sure whether to run it on utilimate, avgas or meth.....

I've had 2 1200 utes and a 120y coupe, and my house mate had a 120y sedan all in n/a form and they all have done me well. I know that they can run in redline no worries at all but how they run under boost with a 9.0 to 1 compression ratio I don't.

Any thoughts... let us know....
