If I managed to get hold of a Tuscan without an engine, What would I need to buy/fabricate/borrow to get a Cerbera 4.5 engine to fit and work ?

I have searched through hundreds of posts but not found any details. It has been done in quite a few cars but there are lots of posts saying everything is different, chassis needs cutting, ECU and loom wont work, ancillaries are in different positions, water & oil pipes are different etc etc.

I was hoping it was just change the airboxes to the Tuscan ones and plug the wiring in (clearly not the case).

If it is so much work is a Race engine cheaper ? (how much do they go for ?)

So can anyone advise what is entailed to get a Cerbera engine working in a Tuscan ???

There is a chassis member below the sump pan, this will need to be cut out or flattened to fit a wet sump in (my car used to run a road engine). You cannot dry-sump the road engine as it only has a pressure pump (no scav), so you'll either need to risk the wet sump and keep it topped up (like Mike used to in his Cerb), or get an after-market belt driven multi-stage dry sump oil pump. The latter is what I'm doing as I couldn't find a new or used race engine or block. My engine is a road block with a modified custom dry sump pan from a race version. The external pump is driven via a pulley in place of the air con pulley, and then the water pumps are electronic external jobbies too.

A race engine in reasonable nick will cost you around £7k (John Reid had one last year I think), though there are no more race blocks available. It would be easier therefore to start with a road engine I'd have thought. You can pick up a runner for around £3k I think; then plan to rebuild it and make some necessary mods for racing.

As for the other stuff, I have a 4.5 MBE ECU from a Cerb if you want to make me an offer, the water pipes aren't different enough to make a difference (they just extend a bit further down on the road engine), the loom is different, but I have a complete set of Tuscan Challenge original wiring diagrams if you would like a copy so not too difficult to re-wire (and I don't think too much is different anyway).

The biggest challenge will be the oiling (as I am currently facing with my engine). For ease and cost, I'd just stick a road engine in there and have the bottom chassis tube moved. If you want to look at dry-sumping, drop me a mail with your number and I'll give you a call. Essentially though its a reasonable amount of work but not a show-stopper...! (I may have a tuscan inlet/airbox thing for sale if you're interested to sort out the induction).

I have a new Tuscan race engine wiring loom sat on the shelf. Happy to take an offer if it is of any use...

Mine dropped straight into the speed six chassis all i needed was a set of challenge car exhaust manifods and a "tall bloke" job done. Engine from a road car IF YOU CAN FIND ONE will cost £5k minimum and it will require a rebuild with all the expensive bits approx another £5k to reach 400bhp+.

Unfortunately, after doing the sums, I’m not going to be able to do this at the moment. Bugger!
I'm currently rebuilding a Chimaera and would have to complete that and possibly sell it, so it's a no go at the moment.

On another note:
What’s a Tuscan challenge, rolling chassis, body and roll cage worth ? 5 – 10K ?

I'd say a bit more than that.. I'd say £12.5k would be a good deal if its all in good nick.

Its fairly straight forward and cheaper to drop a rover v8 in, not as much power but still fairly healthy.

and sticking a rover in is no worse a crime than a road car AJP, you also dont need to mod the chassis and a lot more rv8's about

. . . nothing wrong with the RV8, after all that's what they originally ran before the switch to the AJPs biggrin (from the proud owner and driver of an underpowered RV8 wink )

...and he had a very nice 4.5 ajp once too, so he should know!

(BTW keith, you won't believe your ex-cerb now Cerbera GTFR when you see it wink )

It'll be out in the Challenge this year.

Wouldn't mind a drive of that wink . . . if only to see how it compares to the original biggrin
