Technical KriTip's 1.2 16V Sei Project

Post #196, but it seems you do have things under control (I know I wouldn't swapping an engine). /Woj
 
Ah!

The difference is, because its 16V, and has an extension to the cylinder head that houses the cams, the spark plugs sit about 15cm down in the holes!

It makes removing a pain, and the leads look wiered as well lol. the have really long, gun styled ends!

I haven't show any pictures of my goodies (bmc cda, magnecore leads etc.) so will take some photos tomorrow and you'll understand what i mean then :D

I'm more worried about the dust and bit that have got into the fuel rail and piping whilst i've been working :idea: hopefully all will be fine though :)
 
Here is an exploded view. Its not that clear, but you can see the top of the leads. They go down to just above the pistons, so you can see how far the plugs sit.

Totally different to the 8v, where they come in at an angle form the side of the head.

I think its because there are 4 valve per cylinder, and it has to sit in a more accurate position.

Learn something new everyday :D. Removing might be pain but I bet the plug holes stay nice and clean... I was just replacing my plugs few weeks back and the crap around the plug socket was unbelievable, miracle nothing got into the thread or engine and messed things up.

I guess mostly because it's just that four valves per cylinder take up pretty much all of the space and one needs to find a spot to squeeze in the plug... /Woj
 
Just a quick question for you,

Is there any actual performance advantage in the alternative coil setup you have, I am still on the original 2 x coil packs and they seem to work fine, or is it just to be different?

J
 
There is probably no advantage and there is a defiantly disadvantage that afaik it hasn't been done before and is just another unknown in the equation.

The reason for doing so is that, as it's a mk2 engine, that's what it came with, I had the engine code and ordered the magnecore leads. These leads will fit this coil pack and not the other style (the 1108, 1248 and 1248 sporting mk1) :( I didn't want to waste the money on the leads AND have to make a mounting plate like emma's project, so figured I could kill two birds with one stone and read the schematics and wire it up.

Not a clue if it will work or not, but it does look neat :D

I guess the only possible advantage with regard to coils is COP, ie, sequential spark. However i will need and £800 ecu for that ;) The Panda 100hp and other 1368cc systems use COP, but even emma's project went for wasted spark.

Much more benefit comes from sequential injection which the punto mk2 does does above a certain rev speed, hence the cam sensor, and therefore presume the mpi sei does as well!

Cheers,

Kristian

Plugs central, this means the flame path to all areas of the piston is equal in time and distance. More efficiency loading on, pressure across, the piston and an even burn. More economical and more powerful :)
Some early american hemiheaded 2 valve per cylinder designs had a central plug.
 
Just done an online insurance quote and and thought I'd share it :D


With lowered suspension and provisional driver from admiral I pay about £320.

HIC, with provisional and mods is £820 or without a provisional driver is £720!!!!

A bit more than I was expecting lol, thats with 7 years no claims.

I'm going to ring up Adrian Flux and HIC on Friday when I'm off, and get a quote over the phone and hopefully get it cheaper lol.

Ayone know any other good insurares that will do engine conversions and mods??

Kristian
 
HIC were the cheapest for me by miles but there again i am old :( They covered my Cavalier and that is a hell of a lot more modified than your Sei.

Is that price on unlimited millage? limiting the millage can make a lot of difference. (BTW Adrian Flux is the same copmany as HIC)

Unfortunatly with highly modded cars the fact that they will insure the car with a provisional licence holder at all is good as most wouldn't touch it.
My Cinq is no driver under 25 and must have held a full licence for 3 years or more and the Cavalier is no driver under 30 holding a full licence for 5 years or more.
 
I've actually only got 1 years NCB on the seicento and paying £438 which isn't bad, as Aaron said insurance companies don't like engine conversions. But Adrian Flux are great, got both my cars with them. Altho the paperwork you have to fill out is a bit of a pain :s

Emma.
 
Well, I'll be happy if I can get it down to that level, not much more than I pay at the moment!

I'm sure if I ring they will get it lower, and I'll try HIC and Flux, even if they are the same company, they will offer different prices. Lots of insurance "companies" are owned by the same owners.

I have to admit though, the ladies seem to get it cheaper :D maybe I should insure the car in the gf's name on provisional, and I use it. Prob be cheaper ;) (joke)

I was so interested by insurance I forgot to update my progress. :)

I fitted all the cooling, and filled it up. I used the 16V water pump pipe, not the 8v, the reason for this note, is that JR mentioned his had to use the 8V coolant pipe from the pump. However, he used a mk1 engine and mine is a mk2, so that is probably a difference.

After the cooling, I refitted the bumper (no problems here). I also installed the drivers side light. As suspected, I just had to cut the mounting bolt short, and it installs fine then, with no problems.

I installed one sides wheel arch liner, thread locked the cut down studs, and wired up the battery to test the basic electrics. The pump still primes (no leaks (y)), the lights all work, and I put the windows up to stop any more dust getting in.

If it wasn't for lack of gearbox oil I would have tried to fire it up, even though the MAP needs wiring and there is no throttle cable. These are on the todo list still.

I have the GB oil now though, and will be working on it on Thursday, so that MAY be when I first fire it :eek: I'll take a video of the momentous or horrific occasion :D

I promise more pics soon as well :cool:

:) Cool :) Nearly there!
 
:D :D :D :D

Booked the day off today to do some more work. Started with a 30 mile cycle ride to the scrappie to find a throttle cable thats long enough. The donor car that was there on the weekend is now a cube though so was a total waste of time.

Popped into fiat research though and they are getting in a cinq and punto cable for me to compare to mine (y) They will be i tomorrow and hopefully one will suit.

The afternoon was quite successful though! Did the final wiring, gearbox oil, checks ,etc and then it was time to fire it up....

I know I said i would record the first start up but was too nervous and it failed :cry:


It was trying so i knew I had spark and fuel but couldn't figure out why it wouldn't go. I was very annoyed and thought of the 1000 reason why it could be, including my custom coil pack wiring.

After and hour though, I traced it down to my crank sensor bracket being just to far so it was seeing pulses, but not as many as it should! spacing it with washers and it fired straight away!!!!!!!! :slayer:



Anyway, here it is :)

Throttle pulled by hand, and induction looking like a periscope lol

Now I'm off for a beer to celebrate :D
