The heads on carby, efi and turbo efi are the same, the cams are different obviously for each application but the head will need to be removed to install some form of decomp device like a thicker head gasket ( I used a cometic 1.9mm thick head gasket which was the minimum gap I needed for a un machined head ). The only difference between the looms between the turbo and na was the turbo had a knock sensor near the oilfilter, the na loom should have the wire there but you'll just need to get a plug and sensor (in my vl I used one from an r33 skyline). The distributor is different between carby and efi also. There is a difference between the plenum chambers on the na and turbo motors being that the efi has larger runners and makes the motor a few extra ponies with the turbo but unless you run straight lpg or take the gamble and wait to get epa'd your best bet would be to run the correct manifold for turbo. Turbo injectors are also larger, to feed them you'd fit a high volume high pressure intank fuel pump or a surge tank and external fuel pumps. The other main difference is the ecu's, the turbo has a second mother board internally for the knock sensor. The good thing is auto computers can be used with manual cars but not vice versa.Quote:

I would use vl turbo parts if I was going to keep the car easy to maintane or keep the rb30 block and fit and efi system from an rb25det r33 skyline depending on what you can afford or how far you want to go with adding power and efficiency, obviously a DOCH motor is far superior to a SOCH motor but like I said it all comes down to cost
Yeah I do have most of the gear ( mainly the harder parts ) for efi and the turbo conversions.Quote:
