Re: what are the differences between the 2.0L 8v turbo Fiat Croma lump & Lancia versi

didn't the lancia one have the ballancer shafts? if it the origional croma that was the legendary fiat twin cam.
I think the management was different too with fiat using marelli and Lancia using Bosch could swear to that though
 
Re: what are the differences between the 2.0L 8v turbo Fiat Croma lump & Lancia versi

I don't know much about the 8V engines having never owned one or worked on one.

Though they may have different sumps, Lancia's for the FWD transfer box and gearbox arrangement, I know thats a differance on the 16V Coupe and integrale engine, though on those there are different part numbers on valves the Lancia's being way more expensive, probably due to getting them homologated for WRC, though in road trim not really needed.

All integrale's run Mag/Mer management, as do Ford Cosworths of similar age, only the Escort getting Ford's own ECU. So many parts like map sensors, ECU upgardes etc are transferable between them.

I thought all the Lampredi Twin Cam turbo engines had counter rotating balancer shafts, but maybe the Fiat one as Allenhelen points out do not, this is no issue as some people remove these and blank off the end with specailly made caps as oil passes through there.

you could join and ask on http://forums.delphiforums.com/evoforum/start the knowledge base on there extends to across Europe.

The engine in the origional Croma was basically the same twin cam 8v as was found in the 131 but turned trough 90 degrees. There were 3 versions the CHT with a carb, the ie (injected) and Turbo ie the engine was fantastic but let down by cr*p electronics the output was nothing special thought I think the the ie was about 120bhp

cheers for the replys. i was awaiting one from arron, as i knew he was a lancia man also.

the reson i ask. well, i'm fitting the fiat croma turbo lump to a uno, and i know theyre basicly the same lump, i wanted to know what exact differences there were between the actual engines. i.e. are all the internals the same? same turbo? same cams? i know the croma had 150bhp as standard. did the lancia delta version of the lump have the same output?

cheers for you replys so far guys!

Re: what are the differences between the 2.0L 8v turbo Fiat Croma lump & Lancia versi

I assume your talking about the twin cam units, Lancia's used Magnetti Marelli injection type units not sure about Fiats Croma system. They originally did not have balancer shafts, I believe they were only added for the Integrale.
As far as I can remember pistons cranks are the same but Lancia's used a slightly diff' cam profile and had distributors in varying places(but mainly on the end of the exhaust cam), think mainly due to fwd application as opposed to Fiats mainly being rwd.
One thing for definate is that theese engines suffer badly from oil surge problems so for enthusiastic driving make sure you fit a baffled sump.
The bottom ends are very strong and will cope with 300bhp in standard form, a very good engine very torque and tractable.

Hope this helps Dunc

I had a Mk 1 Croma Turbo ie for almost 20 years. (sold it last year) If there's anything specific you want to know about the engine, I still have the original Fiat workshop manual for it. In standard form the engine developed 155bhp.

There's an easy modification you can do to the Magneti Marelli Microplex MED 601B ignition ECU to retard the timing 5º to make it run better on unleaded fuel.

The 2L 8V integrale's made 185bhp and 225lb ft as standard.

how come the integrales made 30bhp more? more boost? or other internal work? different cams?

cheers for all your replys so far, its really really helping!

p.s. sorry for all my questions lol

Most of the differences seem to be explained in the Guy Croft book Modifying & Tuning Fiat and Lancia Twin-Cam Engines (not read it yet -- I'll get down to it after I've finished with the Senna bio) -- so GC's website/forum might be useful to you.

oh yeah, i agree, everyone has to make a living. but £150+ for a book, thats just crazy! i dont even like reading lol

anyway, lets get back on topic, anyone else have lots of info regarding these engines?

cheers for all the help so far peeps :D
