General 16v fiat coupe turbo in a cinq.

OK then..... Ive measured up a Cinq for the same purpose and heres what I know.

The 16v 1995cc TC lump (Coup 16vT block) will fit, with around 2" to clear each side of the front inner wings, although will need to be set further back than the Cinq block to allow space for heat management system parts to be fitted. So that means youre gonna need to find somewhere to put a heater - as the inlet manifold needs to be where that is.

But, its a good 50kg heavier than the 1.1 Cinq block. which is about 10-15kg heavier than the 899cc block, so that will impact on handling hugely.

A RWD install's much easier - all HM parts can go in the front, the engine installed slightly further forward of where the spare wheel was, with the fuel tank crammed somewhere (front's no good for it really, as it varys in weight too much).

Then theres the track:wheelbase ratio and power - get that match wrong and it'll just spin like a top given a corner- look at the VW Polo W12 concept (which TBH the Cinq is very likely to be worse).

Also bear in mind its gonna need an SVA prior to going on the road if doing an RWD build.

Its the reason I have an 8v 2L TC driveline on my garage floor....and Im gonna extend the Cinq rear track to the same as the donor to reduce the chances of the spinning problem.

Oh, and it helps having done something like this before as to get it to work requires an appreciation of the mechanics of such a thing, cos its far departed from a standard engine swap.

As for cost, Id say 5k to complete erring on the side of caution (Im gonna try 2k, but thats very optimistic)

@blu73 - /Power utilisation isnt the problem in the gearbox IME, it seems much more fatigue related because of the torque going through them, and accelerated bearing wear due to the torque, but having been in a couple now, they could benefit from a longer gear ratio in 3rd-5th.
 
Would have huge cooling issues with the turbo at back of bay i should think too.. Nout to stop you building a one off starting from a sporting though, ok theres quite a few cinq turbo's out there but theres always something that can be done differently.. I mean is there a 16v turbo yet? (theres one in the making though) or look at emms NA Sei with 1.3, thats pushing nigh on 100bhp and nothing stopping you doing that and turboing it. And alex's old 1242 high boost is the only one i know of in this country.

Owning a cinq turbo i would say though that you don't really come across many others on the road, you'll still have a special car even if its the same as some of the ones on here. Personally I think the next big thing that needs developing for the cento turbo's is a gearbox as although the standard is plenty strong enough a purpose built one could utilise the power much more effectively.

My sei is a 1.4 :p

I kinda agee with that but i was thinking more 1st and 2nd are too short, being that a standard sporting is quite nippy off the line due to the short 1st and 2nd and is nigh on impossible to lauch as fast as it could with slightly longer ones i find 3rd and 4th good but 5th could defo do with being longer. Ideally i would want a punto 6 speed reworked but theres much more stuff to be done before i getto that sort of thing. This will, i suppose come, downs alot to your particular driving style and what you want your setup to acheive. My thinking on the 6 speed box would be to have blistering acceleration 1st-4th and a longer 5th & 6th for cruising.

My bad, someone needs to build one like yours with a turbo ;)

Had good look at the T-jet engine on the Bravo and Punto. Both incorporate the turbo in the exhaust manifold as all modern turbo's car are, means turbo is as close to engine as possible so reduces lag, and is before the CAT which are incorporated in manifold as well so they heat up as quickly as possible to reduce emissions.

All the 1368's use MLS (multi layered steel) head gaskets as well, different part number on T-jet engines, these can be used on other FIRE engines with some small modifications to the gasket on two water ways.

We have the MLS gasket from the 1368 engine from when we opened it up for inspection, and have compared it to earlier style gaskets.

On new gaskets they reduce the amount of water entering the head on the inlet side but increase it on exhaust side which is a good thing.

In process of buying a T-jet head gasket to see the differance in thickness to the N/A gasket as from Fiat pricing its about £10 dearer and although only an assumption until we get it, think its just more layers as N/A gasket is just 2 layers and about 0.6mm thick, so turbo gasket probably 4 layers 1.2mm thick.

Have to remember MLS gaskets do not compress like standard gaskets do so although thinner than standard to start with differance once clamped will be less.

Forgot to add Emma's Sei has more than 100bhp, not approaching......

ok well what reasonable engine could i fit to my cinq what is quite fast and not breaking the bank 2 much? thanks.
 
difference between spi and mpi please and what do you thuink is the better option? sorry im still learning. thanks.
 
lots of this on the forum, and faq's, maybe have a search about ;)

spi - single point injection
mpi - multi point injection

ie. one has 1 injector, one has 4

to deal with this they have different inlets, throttle bodies, engine management systems etc.

If you are serious, do a lot more reading...there is a fair bit involved from a 899cc and can be expensive.....also consider insurance if your young.

sorry just realised that when a word is underlined it gives a definition lol. So how much do you think a 1242 mpi
or 1242 16v mpi would cost?
 
1242 16v mpi

engine - £200 min
ecu - £100
exhaust changes and manifold if it didn't come with engine - few hundred
induction - £50+

plus all the extras and loads of other stuff needed like bigger brakes, arb, lowering - saftey and handling stuff.

For a 899cc i wouldn't budget any less that 1k minimum.

If you young, expect massive insurance of several thou as well.
