I have a W115 with a 173cu" Holden (GM) 2.85 litre straight six cylinder in it. I have put on a 350 holley carby, cain manifold, 9" redline filter (Removed for CAI when driving) and has stock exhaust manifold going to 2.25" exhaust straight through with walker super turbo muffler at the rear. I have a massive radiator from a 3.8L 1995 Commodore (With same buick engine) and big thermofan which takes up the whole area behind the grille.
It's a nice engine because its grunty, has a mean old school note to it, and goes ok. However I REALLY want to change the engine to something else because it really unefficiently guzzles fuel.
I can get a 3.8L V6 with a four speed electronic 4GLE transmission and tailshaft and whatever else I need for about $200aud off a mate who has a donor car. The only problem I think with this is the fitting in the engine bay. Castlemaine rodshop have engine mount kits for Chev/Ford/Holden and Ford 6's, so I was thinking about just going with them for the ease of conversion.
I want something newer, thats reliable, and that will rev hard. The 3.8L V6 is a good proposition, but it will involve alot of work. The car is registered as a six though, so maybe I can get away with it if police pull me over and ask whats under the hood, and the radiator and thermofan is already installed.
I want something smoother that doesnt leak oil everywhere... I've had enough of carburettor engines, basically.
The Skyline front cuts go for pretty cheap, and Im a nissan fan, however I have ALOT of bits and know the 6G72 engine well... but Id like to go a turbo six if anything.
Basically I want to go all over the road changing into second gear smoothly with a mini spool diff... what power in a W115 do I need to do this?
