TVR Speed Six question

[RR-Eng]

Does anyone know how much a TVR Speed Six 4.0l engine weights and what its dimensions minus gearbox are are?

Same goes for an Alfa 3.2L V6.

Cheers

The Speed Six weighs approx 145KG,, slightly lighter than the Rover V8, but 20KG heavier than the AJP V8 (It is also 100mm longer than the AJP V8 due to it's in-line arrangement)

Hope that helps

The AJP V8 was reputed to be able to fit in a 22 inch cube

and the AJP V8 is so much better

No,, it isn't

You surely arnt going to try putting an AJP6 in a front wheel drive Alfa!?

More sensible to put an Alfa V6 in the front of a Tuscan, I'd have thought. The Alfa doesn't blow up with quite such monotonous regularity.

I haven't decided what I am going to have a go at yet, I am trying to get some more detailed info on engines and drive trains.

I did recently have the idea of doing a rear wheel drive conversion of a Fiat Coupe (I own one so I think they look pretty good ) which to be honest I haven't fully thought out yet.

Currently my thinking is I would want to reduce the cars massive front weight distribution biase. As far as I can see the best way to reduce this would be to use a Porsche 968 transaxle and mate this to a short relatively light weight engine that can be mounted as far back in the engine bay as possible. (This would appear to rule out a speed six on this criteria, the orginal Fiat unit is far too heavy as well)

However my basic calculation appear to be suggesting that the basic constrignts of the floor pan are going to make it hard to get a proper weight distribution, it is after all Tipo based.

There was a TVR Discovery conversion some time ago but that was using the old TVR/Rover V8's, it wouldn't surprise me if TVR wouldn't sell their engine to anyone.

the fiat 20v turbo is a good little unit. read about one in a Alfa GTA in track and race car a few months ago, was making a "reliable" 500bhp! that was rear wheal drive to. will see if i can dig out the copy and see what box was being used.

you could always go the traditional ford route. you can get a Zetec long block thats buildt to handle 500bhp @ 26psi for about £3700 from Autocraft i think. or if you wanted to keep it italian then there is a guy building 3.2 alfa V6s with twin turbos! 550bhp was what he was running from the one in the back of his Ultima GTR!

there is also the Chevy LS1/6 engines (or the 6.0 ltr LS2) wich are cheap and widely avaliable. 400bhp from the one out the Vette and i think real steal do a adaptor plate to atach it to the Cossy box!

or you could wait for a TVR to crash and nick the AJPV8 and gearbox.....

thanks Chris.

The only problem with the Fiat unit is that is isn't little its got a case iron block at its quite heavy. The barchetta 1.8 unit is 146kg and it is a 4 cylinder cut down of the 5 cylinder engine, I estimate with turbos and all the plumbing in the engine is not far short of 200kg. Plus it is quite a long engine and when mounted longditudinally it is going to require reshaping the bonnet and will also shift the centre of gravity forward. At the Fiat Coupe Club (FCCUK) the most powerfull coupe is running at 440bhp, as far as I know nobody with extreme power upgrades has actually required to change the gearbox. or you could wait for a TVR to crash and nick the AJPV8 and gearbox..... How often does that happen thanks Chris.

I am suspecting a tunded version of one of the various 3l V6 units is going to be the shortest lightest (and cheapest) engine to fit.

Anyone have an idea of how much a Noble engine (or equivilent) would cost.

The whole internals of the engine are upgraded (forged pistons etc) or every mad dog and his mondeo would be pushing 400bhp by now!

[chuntington101]

have you looked into the VWA groups 1.8T unit? cheap, reliable and can produce good power. also as they are used in everything there are loads of them knocking aobut. 350bhp isn't hard to get and that would be reliable!

then htere are the Zetec and Duratec units, buth very good.

thanks Chris.
