HiHi there, I'm just hoping you could talk to somebody that really knows the Fiat twin cam engines well. I'm trying to find out about parts interchangeability, turbocharging, etc. Thank you
Hey there, thank you so much. I really appreciate your quadrant I'm not sure that's going to help me figure out how to build a copycat thema turbo engine!Hello,
On the bottom of the forum banner you've got a link to ePER, it's a FIAT spare parts catalogue. You can browse by models and categories or search by VIN.
Having a specific part number you can search which models the same part was used in.
Of course it will show you the 'official' interchangeability only.
The search window is top left of the screen.
Good luck![]()
Is the linea a good base to build a turbo and will the thema turbo manifolds fit up to it? Is there a site that lists the various transaxle types? I'd I've that book even though it doesn't seem to cover the modern stuff...prices are eye watering.....Hi The 8v turbos we’re based on the 2 litre block. All blocks are interchangeable the later FWD cylinder heads are reversed port so that the exhaust side is on the right hand side looking from the front of the engine. Try to get hold of a copy of the late Guy Crofts book on the twin cam it’s an excellent reference source.
Just in case, ePER covers Themas since 1988 :Hey there, thank you so much. I really appreciate your quadrant I'm not sure that's going to help me figure out how to build a copycat thema turbo engine!
And the 16 valve?All the parts on 8v such as manifolds are interchangeable. You will find that there are various different water pumps and front pulleys etc which need to be matched. By linea do you mean the car based on the Grande Punto. Maybe explain what it’s you’re thinking of building.

Good point on the bonnet clearance! the Integrale bonnets was very slightly raised compared to the HF Turbo and HF4wd, although the HF4wd was a 2.0. still something i will look at closely thank you.That sounds interesting. Yes it will work as you’ve described. The only thing to check is bonnet clearance as the block is taller due to the longer stroke but it should be ok. With that spec I would expect some heathy power.
