Agreed.

The Croma T too had a small overboost function, for 10seconds or so. A magazine here when new tested it to 165hp.
That turbo had a VERY small turbolag for it's time due to it's small size. This also mean it runs out of puff quite early, nothing strange about that.

If you're considering PRV/PBV I'd suggest you check the fuelling first so you don't melt any pistons..

Great to see this up&running anyhow!

Cheers for the positive comments guys. Yes it is going to be road legal. The certification tag for the modifications is supposed to show up in the next few days after which I can register it again.
Unfortunately the motor is sitting on the shed floor after a little bit of a meltdown at a trackday yesterday....
I think there was an airlock in the cooling system leading to the bottom end overheating in a short time. Cruddy sump design and general old age of bottom end (250000km) wouldn't of helped either. Temperature gauge (off sender in head) read normal and first warning of trouble was rattle and power loss
The sump is full of bits of big end bearings and the crank is stuffed but the block will be salvageable i hope.
I took the opportunity to take a pic of the oil squirters for whoever it was that asked
I also noticed an unrelated problem that had solved itself with surprising little damage. The piston recess is not symettrical and i had not noticed and neglected to rotate them 180 degrees. The inlet valves had been skimming the pistons and made their own recesses!
So now it is rebuild time. Not too big of a deal as i was planning to freshen it up anyway. Will rebuild with another crank and pistons, overhaul turbo, put some wings on the sump and fine tune the coolant plumbing a bit. Will try and get the turbo oil drain a bit further from the oil pump pickup for good measure too. Oh and fit an oil pressure and oil temperature gauge!!!

You must have cranked it to have the engine out and in bits by now!

Bad luck Nick. Im surprised the valves touched the pistons with the huge dish like they have, and with turbo cams. Do you mean the piston crown is not symetrical exhaust side to inlet? Maybe using the old head with the chamber spacing issue is the cause?

It sounds like it went like my Tipo. Overheating a little, coolant at 110, oil at 100. No big deal, i'll cruise down the road to cool it down, it didn't cool down. Then I noticed a little knock and a lack of power. Oil temp jumped to 120 odd in a few seconds. game over.

no not symetrical ...look on the last pics from my shiguli projekt ...

@Nick look out for new 1600hf(first series)pistons they have a little bit more Cr (8,4:1)

yeah, doesn't take long to rip apart when it hasn't been together long enough for everything to be stuck
The piston dish goes a couple of mm closer to the edge on the inlet side. It even has a little arrow stamped in to show you
Cheers for the tip mad. Will see what i can find

well i did a little more damage than initially thought...
Mostly done to oiling issues but it must of jumped some teeth on the cambelt to explain the piston/valve damage.
head f#*ked (cracked casting, four bent valves, broken valve guide)
cams f#*ked
camboxes f#*ked
crank f#*ked
rods and pistons probably f#*ked
oil pump f#*ked
Its coming along now though. Turbo has been overhauled. Bottom end is rebuilt with replacement crank and oil pump from a croma i.e, and rods/pistons from an 8v integrale, new rings, bearings. Replacement head has been sourced and overhauled. I think its another 1800 124 head but someone has ported/polished it at some point and it has non standard valve guides and springs. Not too sure what the replacement cams are but are likely n/a and look to be high lift so it could be an interesting combo. I figure its easy enough to change them (the cams) if they prove unsuitable. Hopefully it might be a bit more of a revver

Nice one Nick, keep plugging away and tell us what is like with the rebuild motor fitted.

Well Nick just came around to help me put on the gearbox/sabotage my X1/9 build (if the ring gear hits the starter motor then it is his fault!)

We went for a blast in the wee 124, he even let me have a drive - a true gentleman....

I can say that it goes very well, obviously a smallish turbo, but there is virtually no lag and a huge gob of torque and it is very easy to get things loose - nick was trying harder than I was tho

It made me want to get my old Lada wagon back and find a Thema Turbo......

So Nick, how does it go against the 131? (with a decent fuel pump )

Haha hopefully it was more help than sabotage but you can blame me all you like if i'm wrong. I'll even try not to laugh!

Yep, 124 is back together and running well after a few wee setbacks. Oh and its road legal at long last! Its great fun to drive... always brings a smile to the face

Steve i'd conveniently forgotten about needing a new fuel pump for the 131!! Performance-wise the two cars are very close. Theoretically the v6 has a few more hp and a bit more torque (although at higher rpm) and they have the same gearing. The smaller size of the 124 and the low down torque make it feel quicker but i reckon the 131 could just beat it. I guess there's only one way to know for sure and i haven't had a chance yet

The only true way to find out is a side by side drag...

And so purely in the interests of scientific enquiry I put my name forward as the second driver *cough*

seems like a good idea to me... I win either way

Speaking of which, a perfect opportunity.....

Some pics of the finished car. Its been behaving well since the rebuild

Does it go any better or worse after the rebuild?

Nice new driveway

cheers Steve
There's not a massive difference but I think its definitely a bit stronger than before.

hello nice project!!

I have a few qeustions for my rebuild 124 ac coupe.

I can buy a lancia 2l 8v turbo engine the one whit the balance shafts from 1994.
is it possible to fit de head and pistons etc. on a old style fiat 2L 8v 132 block.
it's very dificult to find a old model croma in holland the most are rust away.
but the 132 block do not have the oil squirters is it a problem?
