Im gonna be a muppet here, but i think its the 8v bottom end and crank you use

You can use the p75/060 bottom ends, but they are the same desk and casting. They are even the same stud pattern for the heads (what you can put 16v heads on 8v engines ). Water jackets are open block side(both 8v and 16v) and then the head has the pattern. I think the threads are the same for the head bolts too.

Am i missing something here?

you have a perfectly good car with a perfectly good engine why the hell don't you just use it?

16v pistons with your set up will just make the car slower and less drivable due to the much lower CR.

if you want to build an engine for the car do it as a separate project

Allen, who was that aimed at?

Thanks

The man with the flash van

the guy with VAD pistons in his lovely Hi boost siecento

it is one of the nicest tubbies around and considering the amount of use the car gets it really isn't worth it

tell you what chris I'll swap you your car for my TAG watch at least you might actually use that

i have not used a watch for much much longer than the last time i drove the sei
Its my car and i shall make it 1242 if i like and i don't trust them pistons with more boost. I have had a pay rise recently and i have cleared all my credit cards and now i feel like spending some of my spare time and cash playing with my tub, is that so wrong?

Chalky's new engine looks :yum:

may be do the rebuild once you blow this engine up with higher boost ?

Isn't VAD pistons just machined standard piston?

Well i have just got this bottom end and i have a spare head and countless random bits. I was only gonna take it apart to use the crank and rods etc but as i understand it now i need to use the 1.2 crank etc so no need to take the sei apart to do this, just drop the engine out and swap it one day when its done.

That atually makes sense Minq

I would say get the feulling and electonics right first on this engine (eg MPI & a megasquirt) , then if you get something wrong and melt something you have not really lost anything if you were planning on changing the engine at some point anyway

OK piston rings, never bought them before. Should i call fiat and get genuine parts or go aftermarket? And if aftermarket any particular brands either recommended or not??

See if you are using the pistons that is from the block, then i wouldn't bother changing them ... and if you were to get it hone, then get the machine shop to get them for ya. They need to measure it.

Agree with ming on that one, they need to be the correct fit for the bores after honing.

Rings will need changing as they haven't seen oil in quite some time, I wouldn't personally re-use them due to the amount of time out of the block.

Thanks

OK coolio. ta

Any progresses? Nice car, at the first sight looked for me like Emma's Seicento

funnily enough, when i bought this car, it was choice between this one and Emma's old turbo.

Update wise, not alot no. The car has been out blasting about recently (my daily was in garage for a while getting some work done and an MOT). During said period the exhaust started blowing, quite badly, and then the MOT ran out on it couple of days ago.
So its going to have to wait for an exhaust before i can MOT it again - have been so busy with work i not had time to take it to a custom exhaust place. Its only like an hour&half to the place i taking it but thats 3 hours driving plus the time to get the exhaust made up and thats a whole days work i've lost.
We nearly lost a big contract at work due to getting behind on delivering reports to the client and they threatened to cancel the order so we all been doing extra long days and weekends to cover it. Hopefully have some time soon to sort it out

edit: the engine is still in the pipeline but i'm not rushing to get it done, i work at a snails pace i'm afraid lol

So not alot going on here, nothing changed yet but should have a nice bonus from work in the bank this week so she prob about to get some money spent on her.

But, 1st things first, she is losing water from around the thermostat sooo, need to fix that.. So may as well fit a lower temp thrmostat while its off.

Now i know this has been spoken about various time but can't find the answer.. Are people still buying a different thermostat and swapping the inners over or is there one that just bolts on??

yes, follow the guides and get the one from halfords, there is even a part number in the guide!

Ming

For te standard thermostat, just buy the complete unit. For the low temperature one, you can either swap out the innards (post somewhere by J333EVO) or try to get hold of a low temperature one (certainly available in Greece, but difficult or impossible here).

i always forget to check the guides, yes i'm bad...

dont bother with the one in the guides... it is useless.

if you can order a proper low temp stat then do.

I run standard after endless trouble for over a year.

Worked OK on Imola Blue -- I still have the prototype!

The "real" low temp ones Asteris was kind enough to buy a batch and post them out.
