hi im new to this kind of forum thing. i own a vh sle with a rb30t conversion i had the car on the road for one day and blew a head gasket its a na motor with the turbo gear on it with walbro fuel pump it is running 7psi can any one give me some tips ect how to have this car run right thanks very much Some original photos have not been recovered yet.

is it intercooled that would be my first start check computer too it may be an na comp

yeh its a n/a comp and intercooler first on the list while im doing the head. wher could i get a turbo auto com from u think cheers

Yeah N/A computers have different fuel maps, so I'd be careful when increasing boost. Running 7psi on a N/A computer will increase the factor of pinging or worst detonation. You need a turbo computer to allow for a fast burn through the cylinder.

sweet as i thought so it does ping slightly at the top of the revs so i have to get one cheers guys very helpfull

im running n/a injectors n/a computer high flow turbo, external gate with no probs????

You need to replace the headgasket first.

try your luck on here..just put up a wanted thread or keep an eye out on forsalee.

thanks 5pdvl im doing it tomorro i havent driven the car . is it a better option to go a cometic head gasket with a set of head studs instead of normal bolts????

also can u run yor air flow metre in your cooler piping instead of the turbo intake a mate said to do it but im not sure. this is my first rb30 turbo

Not sure, gotta install my boost gauge. When i first got it, the vacume line from turbo to wastegate had split in half from melting on the exhaust manifold. **** it went hard. and it wasnt pinging

you got a knock guage? they are over 1k.. it will be pinging.. the injectors cant flow enough fuel.. no two ways about it

i know what pinging is, it was not pinging It is not high comp tho. Some original photos have not been recovered yet.
