I've built the same engine with the MLS gasket but yet to fire it up. Valve clearances seem ok, engine turns by hand fine. Ming told me he's running the MLS gasket.

I was gonna run the car on the 1242 ECU but decided to do it properly and run an Omex so need to get me head around fitting it. What injectors and fuel pump you gonna use?

1108, 1242 & 1368 flywheels are basically the same just with different size friction surfaces. I have a stack of them in my workshop!

That's very reassuring.

Hoping it'll work well as bog standard, that it'll be within the ECU's normal range to read its sensors and make on-the-fly adjustment. Someone says we may need to increase fuel pressure.

I like 'Proud to be rolling on 13s'! What do you do for brakes, inside 13s? AIUI, same-size but vented discs from e.g. Punto GT or Uno Turbo don't improve stopping, just postpone fade.

I have the Punto GT setup, its a bigger diameter disc for a Cinquecento, Alfa 145 calipers on the rear. Mine seem to be the only 257mm vented behind 13" wheels due to the excellent clearance of the Revolution wheels. They won't fit behind standard 13s.

If you are running the 1242 exhaust you will need to modify the alloy sump as the downpipe rubs on the sump. I'm going to cut that part of the sump off as it has no oil in it and is just used for bolting the 1368 exhaust to it.

Re this project to put a 1368 Stilo bottom end under the existing standard-spec top end of my 1242 16v Punto mk1 Cabrio, engine's in, all connected, turns over, but no spark and no fuel pump. Dave knows what he's doing, has tried everything.
Wierd because nothing's changed as far as the ECU's concerned - it drove into the shed OK 2yrs ago.
Any ideas?

Not read everything in this thread, assuming you are using 1.2 16v ECU.

Is the immob light coming on or off ?

Thanks
Ming

Yes the whole head, fuel system, wiring, ECU is completely undidturbed - just disconnected/reconnected same - the only change is 1368 block substituted for 1242.

Immob light - is that the key symbol? Can you confirm that and I'll go check. thanks

Yes it is, its should come on and off. (yellow key symbol)

My 140k vgc 1368 Punto mk1 Cabrio as of today is taxed MOTd and insured and is incredibly lively, tho still limited to 4500 on effectively a new engine (rings, bearings etc) - it worked! The unaltered 1242 ECU copes fine with 10% bigger capacity and higher CR.

Well that engine (previous post) put a rod thro the block so we've been building a new one, with 1368 Star Jet (Punto Grande) block instead of that one which was 1368 FIRE (Stilo mk1).

The only thing you do have to be careful of is that some 1.4 blocks have an extra oil way in them that the mk1 punto head doesn't have this was present on my 08 block out of a grande punto

Yup I see 2 extra holes on top deck of 1368 Star Jet (Punto Grande) block which aren't on 1368 FIRE (Stilo mk1) or 1242 FIRE (Punto 16v mk1) blocks.

the top head of the 1.4 16v have oil hole from the block to the head to lubricate the camshaft adjusting system

I'm putting an ex-1242 16v mk1 Punto head on top of that Punto Grande block and it doesn't have matching holes so doesn't need that oil supply. And strangely the steel gasket for (I think) Punto Grande (or perhaps it's a Stilo one) doesn't have those 2 holes.

Question is, does the PuntoGrande block itself rely on oil circulation via those holes into head and back, or will the block be happy to have that particular oil circuit blocked?

Wouldnt it leak oil through the gasket? If there is no hole or seal for the hole?

Hmm. Even with a steel gasket? None of its holes for waterways and other oilways have a built-in seal around the hole - not like you get with a thick composite gasket. It didn't seem to leak on the 2 short test runs I mentioned.

Interesting. I have not seen a steel gasket only perforated steel within gasket material. Iv heard of thicker copper gaskets for turbo use though.

Are there other matching oil galleries?

I can't go look at it now because it's built-in but AFAIK it's standard 1368 FIRE and 1368 StarJet (PuntoGrande) kit 0.5mm thick, whereas 1242 FIRE standard is trad copper/composite 1.5mm thick. I'm using one between 1242 head and 1368 StarJet block. I think the thin steel gasket could be used on an all-1242 engine to replace the thick standard gaaket for raised CR, subject to valve-to-piston clearance check.

AFAIK it's just 2 simple thin steel sheets without swaging or anything around the hole edges - amazing it seals. There are many water and oil holes that seal betwen head and block, as well as the bores.
