The only car I can think of that comes close to that description is an early Maserati Biturbo. If that is the case, could you fit an Alfa V6? The 2.5 with 190bhp from the 156 must be cheap as chips and easy to find. It would sound a lot nicer and more authentic than an I4 as well.ks anyhoo).If the V6 doesn't appeal there is the also the Nord-based Twin Spark from the 75. 150hp out of the box, chain driven cams and if you want to throw ITBs etc at it, 180hp is easy and 200hp+ is possible at a cost.

And so do many other manufacturers engines. That's a bit like saying a dog is like a human being because they both have eyes, ears and internal organs.
Or in turn, that Hondas 16v lumps are like Lancia DOHC V fours because they have screw valve adjustment. I mean, really! 226bhp said:
If Toyota did look at Lampredis design they didn't take much from it. The heads bear no resemblance at all and are nowhere near as good, it doesn't have any balancer shafts, the bore and stroke combo make it a 'square' engine and the block cracks if you give it too much power.
Yamaha did a lot of the design for Toyota, especially the heads, so you'll probably find more in common with them on an FZR 1000....
I will look at the pics in Mr. Croft's book and report back. Yamaha did a lot of the design for Toyota, especially the heads, so you'll probably find more in common with them on an FZR 1000....
Too much power in the case of the Toyota lump is just short of 700bhp, which is pretty good by any standards, and better, AFAIK, than anyone has got from the Lancia block and head. Doesn't everyone going for real power delete the balancer shaft (which, IIRC, were a later addition)?
Now you've got me in a place I didn't want to go, comparing two great engines.
It's true that some pre rev 3 blocks cracked, but no-one seems to know why.
Too much cylinder pressure. There have been quite a few Lancia engines North of 700bhp, the Greek dragster did way over that many years ago and the Toyota blocks have been known to crack at much less than 700. The lampredi 16v was never fitted to anything which was any good for drag racing, this didn't help its aftermarket development.
Do we have to have rampant Fanboyism here too? I come to PH to get away from it, although you won't be able to make a sensible and valuable comparison from any book, you need both in your hand, on a flow bench and on a dyno.

So, I like both engines (did Lampredi ever come up with a duff engine?) and suddenly I'm accused of being a rampant fanboy? Of what, exactly? I also like just about all the Ducati engines, the old Lancia V 4 (cunning design). The FIAT FIRE lumps (again, mainly from a design/production engineering/ease of working on standpoint, although the power to weight ratio isn't half bad for a car engine), Toyota's little 4A-GE, and the 5 pot turbo Volvo motors. This is not an extensive list.
Strangely, I was looking for a Lampredi 16v turbo engine (on behalf of someone else) the other day, and couldn't find one. It's a cyclical thing, but, with two 3S-GTE engines both pretty much committed to projects (one is my daily driver) and another wanted eventually for another project, I'm unlikely to get my hands on one soon.
I have no flow bench or rolling road. This, presumably, makes anything I say worthless.
Such is life.
If the OP has an early Biturbo, would the engine from a Ghibli fit? They do seem to have a few unfortunate encounters with lampposts on wet roundabouts.

just post it off to Guy Croft for a rebuild.

You didn't look very far for your engines, there are a couple of posts in this thread outlining two sources!226bhp said:

It was for someone else's engine, for a putative Mk1 Punto project. Was looking -- on flea bay -- for a 16v Coupe turbo. If you're saying I'm a Croftie fan boy, then, yep.

Coincidentally my Punto MkI is for sale so I can buy more bits for my X1/9 
Saw the ad! It's a move which I have some sympathy for!
16V's are a shoe in on bike carb's.
