this has probably been posted before but im asking for a friend
what does need to be done to make a 3tgte head on a 3tc block ?..i noticed the cam for the 3tc is not on OHC and is in the actual block but everybody tells me the blocks for either motor is identical....WTF !?

Wayne, the bare blocks are almost identical, just small differences like the oil return line in the side, knock sensor hole, etc. Converting a 3TC-->3TG is like a 2T-->2TG, in that the 3T drive shaft in the block (cam for pushrod engines) needs to be replaced with the much shorter drive shaft in the 3TG, and the oil lobes for this cam need to be pushed over/blocked at the back where the cam once was. The oil pump, dizzy cover, crank(could use 3TC I think), pistons would have to be swapped aswell, unless you get the 3T pistons flycut. and then theres the timing gear on the front.
If you have a look at a 3TG block there is still the holes for the pushrods and cam, so the blocks were slightly updated but no major change, it should be easy converting one to the other. Also the engine numbers both start with 3Txxxxxxx, but I'm sure there must be some records of the difference in engine numbers between the two.
I'm thinking of registering my 3TG as a 3TC with 3TGTE head but no turbo (for now, until I get engineering sorted). Its all complicated, as strictly speaking a 2TG needs engineering as its an import and never came out in a TA22 in AUS, but then its the same block as a 2T. Same said for a 3TGTE!!

i bought a ta22 once which had a 2tg and it had an engineering plate for it, but ive done the swap without one and nobody knew shit about it as the block still says 2t-XXXXXXX
thanks for the info rob!
