Euro vs US

What parts from the 16v Euro (like an 84S) can be used on the US 83S? Is it worth it to find and use them for any kind of HP gains? I had heard that you can use the heads and maybe another part or two.

I plan on adding a Y-pipe but that is about it. I am not sold on spending the bucks to supercharge it at this point. I think it runs fine right now, just want a little more. Not a lot.

I recall reading that everything can be cahnged although I do not have hands on experience.
crank, rods, pistons, heads etc althouh probably easier to find a complete engine.....I know where one is but along way from you:)

There are a number if differences, cams, heads, and intake are commonly changed to get a modest hp gain.

Hey thanks for the quick responses!

This is what I was thinking - then consider the alternative of just getting the original engine right and tight and adding a Murph SuperCharger instead.

928MS y-pipe and hi-flow cat
Euro Intake
Euro Cams
Euro Heads
85/86 stock headers

And does this work make the engine an interference one? Also consider I have a 30$/hr mechanic along with myself to help.

But Stan's option of a good Euro engine outright is another way to go...!

I do really like it as-is, and I am doing the y-pipe this year. So that may be enough for now, enjoy as-is for a while then see if I want more.

If you change cams alone it will become an interference engine! If you are going to put an S/C on it then I'd stick withe US 4.7 as it has a lower CR! That would make for some good fun there for sure!!! The problem I think you run in to with ANY of the earlier engines is tune-ability. The late engines you can put in programmable chips and use a Sharktuner to dial it in perfectly. Not so on the early engines!

Credit where credit is due, Malcolm suggested the complete engine, it is a good plan, and easy to make if you can find a good engine when looking for your parts.

Whether it is an interference engine, is debatable. There seem to be more for it being so, than not.... but I wouldn't want to guess wrong, so presuming it is interference is a good plan.

My '80 Euro S when stock had 300hp as I recall. With a 5L bottom end, headers and a few tweaks, I saw one with 300 at the rear wheels, but it was track only, 100+ octane, etc.

A supercharger can get you over 300 pretty easily, and the higher compression might be a disadvantage.
