94 block with 99 head for Turbo build
 
Hey guys,

I recently purchased 5 engines. Two 99's a 94,95 and 97 all 1.8's. Would the 94 or 95 block be the best one because of the oil galley hole on the side? I've also planned on using the 99 head. Plan on looking for 300 hp around 15psi. All forged internals. I've been reading pretty hard here and it seems that this would be a good combo. Thanks in advance.

94/95 block with the 99 head will do fine

Blocks are the same

I use a 95 block with a 4w head on mine. Oil galley on the driver side is a godsend

I thought the 94 blocks had the oil supply on the driver side, not '95 and later. Check the block, it is nice to have a supply close by. Could be early '95's had it, but not sure. . . .

Both 94 and 95 had it

Late 95's don't have the port. They started to get the "OBD2" engines.
