Got bored of my last project shouldnt have done the body styling so thats being sold soon on ebay....

Heres my new beast.....

1998 Secento Sporting in broom yellow

the mods im doing are:

MK1 Uno Turbo calipers all round
Dropped 55mm on shortened shocks
briaded hoses all round
MG TF fuel pump
delocked
Keyless entry and ignition/start (no key needed to start car all going to be hidden behind dash
Custom dash with 1.5" lcd in rev counter, boost guage, rev counter, water temp and oil temp guages built into dash
Turbosmart boost controller
Tints
going to look completely standard from outside except low and tinted

engine mods.... Currently being done

Punto 75 1242cc engine
punto 85 pistons on 16v rods
fully ballanced bottom end and crank
lightened flywheel
stilo 16v clutch and flywheel
garret hybrid t15/t20 turbo with custom made exhaust manifold ceramic coated inside and out
fully ported and polished head with valve guides cut
multi staged valves
punto 75 MPI head for the larger intake valves
MG TF injectors or punto GT aint decided yet
866 CAM from punto 75
flatted engine block
43mm Tricker TB with port polished inlet manifold modified
intercooler
dump valve

running on megasquirt 2 v3

to come...

Gearbox might be getting a LSD Funds permitting once they have been made

heres few pics of it so far engine is currently being built by zak (slosei) should have for the weekend

pics of manifold to come as its currently at the engineering shop being flatted for a nice smooth mating surface then off to the ceramic coating place

few pics.....

It's a shame you are giving up after going to the effort of primering it, i'd followed that project from the start

nice one gaz... same set up as me guess youll be wanting to borrow my msq

been told to leave the out side bit, Gaz will be painting that,

yeah outside will be getting wirebrushed, and pinted good n propper, look at the flatness its looking good cheers

what the exhaust manifold like, when you say 'custom' does that mean its a prity tubilar peice

it means its no longer a van atken manifold, has a 25mm rounded block on the end which smooths upto the insides of the turbo flange grinded out alot of the metal from inside the manifold then polished it up inside using my porting tool

right i now have my engine back and done a huge thanks to Zak for doing it for me

now ive been told to use my copper decomp plate with this instead of a headgasket....

now the decomp plate i have is 1.5mm thick and made of solid copper.

on a standard 1108cc sporting it drops the ratio to 8.2-1

my block has been skimmed and so will the head be so both surfaces will be highly flat

i want to be running around 1bar of boost maybe more.

if i put this decomp plate on i then have even lower compression due to the punto 85 pistons and the decomp plate.

will this be ok for my turbo application?

why you gotta use that instead of a head gasket? sounds a bit dodgy. most engines that have a solid gasket like that have firerings... this where they mill a ring around the combustion chambers on the head and block and fit stainless (or other metal) rings that seal them.

you really need to work out the CR. if you run to low you wont have any power off boost. horrid to drive.
really you want as high as compression you can that it allowed for the boost you plan to use.

well i was going to use the new flat metal type of head gasket they run in the new puntos but as my heads skimmed and block was thinking it may lower the ratio too much :\

humm.. best bet will be to just work out your CR.
I prefer the standard gasket. it will act as a fail safe(er) incase of over boost

true would save me alot of money if anything ever goes bang :\

yep! i would fit a normal gasket to start with anyway. in fact my engine now has a used gasket lol
when i took the engine apart to fit the 16valve pistons the head gasket came off easy and had only been used for a short time.

I just thought it looked fine and saves me wasting money if the 16valve pistons of unknown history where scrap.

good luck with your new toy mate, it is a shame about your other one, after all that pain and work, but if its not to be, then i guess its not to be, it sounds like you've got some good plans lined up. I don't suppose you'd sell the exhaust off your old one would you?:chin:

Just to get the point accross, measure the CR or get someone to do it.

Burette's are not too expensive to buy. If I had one I'd lend it but sadly I don't. I know JonSpeed mini's in nuneaton sell them in their store and ebay. Maybe ring them and pick one up, not too far

Kristian

also a good way to see if your valve seats are doing the job.

I lapped all my mini valves in(well thought i had) went to measure the CR and half of them leaked

the block has been skimmed so the pistons protrude out the block 0.3-0.4mm iirc
my mistake i thought the copper gasket was 1mm thick
dont want the pistons having contact with the head or valves,rods do stretch dont they? @high revs?
Zak

ill check them when i put the hg on

right not much has been done really as at the mo im wirebrusing all the rust off the block and going to spray it with high temp paint

got my manifold back from the machine shop after being flatted ****ing bank holiday has been aload of **** because post had stopped and none of the things i ordered come so iive had feck all to do.

few pics of my manifold are here just got to send them off for ceramic coating now in white or black not sure yet

as you can see ive grinded out most of the cross sectional bit inside had a new block welded on and tapped (no more crappy elicoils) ported it all out to more or less give it smooth flow inside the manifold

Downpipe looks very VAD! WTF did they MIG weld the damn things and on the inside? Can still see the weld although you've obviously been at it with a die grinder.
