Can punto engines be bolted into seicentos relatively easily?

What engine?

1.2 8v are a straight swap minus a 2cm spacer for the manifold if its an spi for spi ... mpi require minor wiring to be done

as above. although my punto 60 engine (1.2 8v) was a bolt for bolt plug for plug fit. no exhaust mods were needed..... just went straight in.

1.8hgt lump from punto.

Just wondering about physically, not fussed on wiring

yes, anything can be made to fit.... but easy? No. Firstly, IMO (having had one) it's a shite engine. Secondly mounts etc will need custom made, drive shafts etc. Biggest "straight" fit there is (well, for mounts, gearbox compatability and therefore standard drive shafts etc) is 1.4 16v. and that requires some minor work and mount filing etc to make fit

1.4 16v t-jet can fit (new bravo, abarth grande punto and 500), with tweaking etc that's a "relatively" straight forward 200bhp. But good luck finding one and the pot of gold required to buy it.

Whats so bad about it? Is it a soft engine?

They eat the cam timing variators and drink fuel like you wouldn't believe. They also can't pull the skin off a rice pudding low down, not too bad once wound up tbf. For the effort required to fit one to a sei, it'd be better put into fitting a honda b16 or 18 instead (though i measured when i had one and inlet would need altered or heater matrix moved to have a chance of fitting).

Similar characteristics with needing to rev to get the vvti working, but the b16 is a vastly better engine IMO. More powerful too.

Fck it... will see if I can cram a c20let into one, not going to **** about with 1.4/1.6 lumps, if its getting done, its getting done right...

A sorted 1.4 will kill it around 130bhp is the most the chassis can realisticly take, any more means it just won't do corners or get the power down. The weight up front will ruin it.

Though, if you put it in the back....

Rather than starting a new thread I thought I would hi jack this one. Already been looking at engine upgrades not sure if I wanna go 1.2 or 1.4 yet.
My question is, I have the twin plug ecu on my 2001 1.1 Sei. Is this the better or worse ecu to work with once engine have been changed?

Worse as far as i know.

most all 16v swaps i know of run 1 plug setups (and even then new ecu's are required), that's what i'm going for too. for 8v swaps, i'd assume it's the same as the one plug spi's in that the ecu can be reused with a 1.2 8v engine, basically all you are swapping is the bottom end.

So is it worth it with the twin plug ecu then?

The 1.2 8v swap?, I'd say so. It doesn't offer a significant power increase (6bhp... although considering the 1.1 is only 54bhp, that's still over 10% more power, so not to be sniffed at), it won't turn the car into a rocket ship by any means, but the extra torque makes the car feel more relaxed and happier around b roads.

It's something that's the main thing. We'll I think my best plan would be the 1.2 bottom end with p75 cam. Nice intake and exhaust and if it can be done remap it all.

Wouldn't bother with the remap tbh, firstly i don't think many, if anywhere will touch that ecu, secondly the gains from it would be miniscule.

p60 bottom end, p75 cam (don't forget the shims), decent exhaust, decent cold air fed induction will make a decent difference.

Not sure what can be done with throttle body on that setup. (one of the best things about earlier spi setups is the better availability of tuning goodies, bigger tb's, better inducton setups etc) If you're feeling adventurous and possibly not against a little rewiring or ecu swapping, i believe it's very possible to do a p75 swap from the mpi setup relatively easily.

It was mainly for getting the most out of the mods. As I've read that the mpi ecu doesn't respond well to tuning?

Doing all the oily jobs is not a problem for me it's the wiring I don't like working with. Lol

Iirc it scales back some parameters so you don't really get 100% benefit from mods like induction. it "might" cost a few bhp overall, but i'd still not be bothered in getting it remapped, it just doesn't make sense spending a couple of hundred quid on gaining back a 3 or 4 bhp when that could be put towards the cost of an engine with 80% more power.

I'm about to do a **** load of wiring, so i'll let you know how scary/confusing/difficult it is for if you ever step up to 16v power :laugh:

Lol cheers.
