Tuning turbo time!

you got some bits to practice on, and get the machine set up?
Good luckk, looking forward to seeing the finished artical
Ill find something to test it on first. ordered loads of extra bends so will test weld two together just to see (bet ill need to cut some up for tweaking the angles anyway)
I think ill need luck haha! dad reckons it will be a night mare but ive done 99% of the stuff myself anyway so if i can pull this off ill be well pleased
ill defiantly take photos (if i remember... usually the last thing on my mind once i get stuck in!)
if it all does well i MIGHT make one or two more (8valve flange) to sell on
haha there was to much telling me not to do it... first worried about the trailer. but got over that... then seen a couple of the turbo cars go bang lolim sure that if my little bella can do it, you could have man'd up and given it a run
plus the sunday had a large que and our stand was miles away as you remember so would of been a right pain having to get people to move
plan to just go there on a "run what ya brung" day at some point.

12mm is the future mate! That was the only thing that I didnt do right on mine first time - used 8mm which warped the turbo flange within a week. Had do chop it and re-do it at 12mm.
how are you cutting the flanges?

cutting??? LOL goggles/grinder/drill press.... if all else fails the company i got it from can do it for me.
what did you do where the manifold goes to the flange? the ports on our engines are long
I was thinking of tube in a vice before welding them onto the flange to make them oval but not sure if it will work
Got my external waste gate today... bigger then i thought. but I gotta fit it

exactly that - vice lol
I made a mistake when I designed the head flange in CAD, miscalculated what the squished pipe outer diameter/circumference would be, and had to have it altered again on CNC. I worked out out in theory on outer circumference, but in practice it comes out differently, and I still dont know where the missing area went lol. Just a heads-up for you if you're designing a template or whatever.
Only reason I used CNC is because you can get it 100% and my mate runs a machine shop, so it wasnt too expensive.

good stuff
just reading your thread on the punto forum...
the oil rings on EVERY 16valve ive stripped (one under 40k) have had oil rings in many pieces! I compared them to the 8valve and the 16valve oil rings are much more delicate.
I fitted some very low mileage 8valve oil rings on my engine.
ALSO engine rebuilders can get piston ring sets for around £70 so might be worth asking them. might even be able to get you uprated rings for cheaper then fiats rubbish.

I have new goodies that make all that obselete
1.4, forged pistons and total seal rings ftmfw!Cheers for the info about the oil rings though, it puts my mind at rest a bit about det shocking them

OP
I really want to stay 1.2 honestly... but heres an IMACCULATE low milage block, honed especially for the pistons I have, all I need to finish it is some rods...
You dont have any 8v rods knocking around do you? I'm going to ask James/Matt if they have any, but if they dont... PM me please!

1242 8valve rods?

external wastegates...?
can I mount it further from the manifold? centos dont have much room for a manifold like this and a wastegate. would it be ok to have a branch coming from the manifold to the wastegate above the gearbox?

Yes. In fact, it *may* flow more, since the gas will have cooled and contracted slightly.
OP
OP
nice! that makes things easier... guess the wastegate will live longer/be more reliable due to running cooler.
just gotta figure out where to have the wastegate exit... I want it out the side of the bumper but above the gearbox might be a simple hole in the bonnet jobbie lol (cos im lazy)

You know about fitting the gate pipe at more than 90 degrees to the flow, dont you?
BTW answer my PM please I'm busy still learning how to build engines up... is 2.5 thou interference between little end and gudgeon pin acceptable on these engines? Cos the old pins were only about 1.5-2... I know 3 thou is fine on some engines, from a bit of googling, but dunno about this...

so basically make it so the gas is still going in the original direction? the closer to stright the better?
ive seen some proper tube manifolds with the external waste gate on a extra tube fitted into the collector... guess that is the worse setup(just easier to make!)?
yes. 90 degrees isnt great but a lot of manifolds get away with it with big pipe and WG sizes.
You can also do this, if you need to! (pretty much how I'm doing mine, chopping out the IWG, boring out and welding to it)

ok so in my little picture... anything in the green angle is good and red is bad angle?
I seen you butchering that turbo but thats not possible for me. you have better welder/skill and machining to me.
plus i like been able to change turbos so it will just be a simple task as welding a new flange on (or bolting a adapter on if cant be bothered to cut/weld)

is watch that stud pattern on the head, looks like you've got the sort of a pig head like me with an odd stud pattern thats not the same compared to a punto
found this out with my punto SS manifold >.>

yep its a mk1 head. my mate bought a supersprint that never fitted he's mk1 head. so I swapped him my mk2 head for he's mk1 and a spare
mk1 head is better for turbo as the stud pattern is even . mk2 gas bigger spaces between studs because it's made for a manicat
I have a mk2 bottom end which is stronger. .. so best of both worlds
