Technical Seicento Engine Bay Size? (calculating 2.0 16v)

Technical Seicento Engine Bay Size? (calculating 2.0 16v)

Then theres cooling, this will be internally to the car, and fitted in the rear... two large fans and hopefully some inline water pump idea, to take the strain off the pump in the engine (not sure if that is possible yet, will need looking into)...

The battery will also be relocated into the rear also.. .

Hopefully by putting this stuff in the car the weight will be spread out slightly better than it would be if everything was front mounted...

Water wise shouldn't be a prob as a friends a plumber/gas man so he could possibly knock something up.
 
An in-line electrically driven water pump for cooling is more than possible. In fact my turbo Sei' just has an electrical, ECU driven, water pump & we gutted the stock water pump to make an idler cog for the timing belt.
 
Me and a mate have been busy making blair witch project stick frames, one of the engine, and one of the space we have using a frame.... it fits, but as my friend put it, 'its like trying to fit a club foot through a letter box..... its going to be a bit of a squeeze'...

Ive seen one on ebay for around the £45 mark... where would i stand if i was to be keeping the water pump in the engine? As i think the distance in the water lines may cause a problem if i was to only use the engine pump...

Well the one on the gearbox side will be, but i think to be entirely truthfull i might get away with the nova shafts, as the ones on mine look about right, i will have to have a measure up of them also.. but my friends uncle works for a cnc place so some could be knocked up if we need some made

Would rather the vauxhall ones, as then i would be able to adapt the vauxhall hubs so i can fit the 2.0 16v big disk/calliper set up.... rather than needing a pair of shafts with different ends being built up.
 
I think you should work out what the geometry will be like with that short driveshaft, both at normal ride height and at full droop, full bump and full lock both ways. You need to make sure you can actually turn the wheel a reasonable amount without getting it caught on the gearbox or something else, also you could well be wanting wider wheels than the standard 14" to help get the power down.

Second issue I can see (bear in mind I have exactly zero knowledge of vauxhalls) a supershort driveshaft could potenially pull out on full droop or bump. The shafts on the 1.1 Fiat are push in with nothing to stop them popping out if the suspension moves too much relative to the gearbox.

Third issue which is less likely to be a problem is that having one driveshaft a lot longer than the other increases torque steer as one shaft is able to wind up more than the other. Probably not a real problem and might even add to the fun of it but worth mentioning.

That may all be an egg sucking example but something I thought I should point out before you spend months building something which ends up having to have the turning circle of the QE2. I'd love to see this done right.

Cheers for the input, this is the kind of stuff i need to get my brain ticking... at the min my shortest nova driveshaft measures from cv joint to cv joint measures up at approx 7" so is damn small.

Torque steer is a problem, but you can actually buy an equal length driveshaft kit... this wont be on the conversion i do at first as i need to keep cost's down, but its a likely conversion in the future. Im getting used to the torque steer with the nova lol.

Wheel wise i will be needing either 14" or 15" alloys.... this is due to the 256mm valver disk brakes. I am looking to go down the route of big offset, wide wheels with a little tyre stretch... this should hopefully clear most things, and in worst case we will put a rack limiter on.... its not the greatest option, but with the engine that will be fitted, i think its possibly the only option.
 
So you you'd be running brakes without dust seals? I was looking at the midilites, with dust seals, and iirc 273mm was touch and go but 266 was comfortable.
 
Right after a few days away from this ive had a good hard look at measurement's again... this time in mm, with better results than previously. Its looking as if the engine conversion isn't going to be as hard as first thought.

By the looks of it i will still need to weld a lot, but wont need a flip front or a full frame. I will only need to brace a few bits to add strength in certain places.

I will be stitch welding the lot anyway, so shouldnt be too much hasstle anyhow.

As for the driveshafts, i can get 300bhp nova conversion shafts.. the shafts sit fairly in the same place as the standard stuff, but will be slightly longer than the sei... Im not bothered about this as i wanted to widen the wheelbase of the car... so plans so far are to use mainly nova parts like hubs and shafts, and then space the rear out to match with some hubcentric stuff.

I have picked up a c20xe engine for £50 to use as a large stencil (its slipped teeth when timed up by the guy i got it off). So now i just need a cheap sei with engine probs (long shot).

The plan is to build the engine bay to fit the scrap XE engine, then remove it, smooth all the engine bay once its welded and strong... and then fit the XE engine that i will be using....
