Yeah same. Got a mate in Cromer & another in Mansfield with sets so will tap one of them up when it comes to it

I have and will be running a 60l fuel cell. That has a built in trap door style swirl pot.
What does help surging is to foam fill the tank. May help. But with gravity and
Centerfrugal force it would still send the fuel to the ends of the tank.
I had the same problem with the long right handers at Cadwell, lucky the Leon (mk3) there is an in tank solution but when I went to Demon Tweeks they actually advised against (foam filling) it on a Stock car tank as they said it could cause more problems because you would not be able to get the whole tanks filled correctly. As I say I then found the in tank solution and that fixed the issue.

Managed to find someone to make me a horizontal mount swirl pot for mounting underneath. He stocks aeroquip stuff & walbro so said will be easy enough so looks like a decent solution for my setup (hopefully, as long as doesn’t just talk a good game)

makes sense re foam in tank

Inside todays (yesterdays) box from turbo zentrum.

Tial motorsport wastegate. Notable the top wastegates money can buy. Used by many motorsport teams around the world.
20240114_081947.jpg
20240114_081957.jpg

Very well made, the finish and details are brilliant. The anodising is purfect
20240114_082002.jpg
. The finish machining and just the work is brilliant.
20240114_082011.jpg

Comes with attachments for the air supply's and for the water cooling too.
20240114_082027.jpg

The clamps are not just your **** jubilee clips.. proper v band style and with the mating faces for welding to manifolds and down pipes for a proper sealing fit
20240114_082050.jpg

And all the springs in the world for setting up the pressure internally for the wastegate.

Well.. started off well. Cleaned out the block. Slid in the main end bearing. All the bearings in the block run with groves. All the smooth bearings go in the main end caps. Apart from no4 that has a groves shell.
20240114_113755.jpg

Cleaned the crank, all the oil and grease to stop it from rusting. On the main journas
20240114_113752.jpg

Lowered the crank in to the block, wind in the ARP main end studs, place some GREEN PLASIGAUGE on to to main end journals, then ,fit the billet main caps. Fit the nut and wind down to touch.....
20240114_120603.jpg

bo77ox, ar5e, cun7y cr4p... can't torque the nuts down as left my torque wrench at work...🙄

Got a torque wrench from work...... and ordered 1 for home too.
20240128_095707.jpg
So layed some PLASIGAUGE
20240128_100649.jpg
on the journals ...... then torqued the mains down
20240128_095711.jpg

Undo the nuts and remove the studs and then main end caps
The plastigadge has squashed
20240128_100607.jpg
20240128_100614.jpg
leaving a mark on the crank and bearing . Using the scale on the side of the packet.
20240128_100620.jpg

How wide the stuff has spread shows how thick I squashed down too.
20240128_100645.jpg
20240128_100649.jpg

So mine are about 0.0022 though oile clearance.. they recommend. 002-.0025 tolerance. So bang in the middle

Then on to sizing piston rings. Clean the bore and lighty lubricate the bore. Using the piston upside down . Push the ring about 1.5 inch down the bore
20240128_172015.jpg

Using feeler gauges measure the gap
20240128_172020.jpg

Using the calculations supplied with the pistons. The top ring needs about .04 mm clearance. Basicly if the gap is too big you will loose compression. Fuel can the enter the sump, you won't get proper compression and ignition of the fuel air mix.
If too small then when the rings expand they can hit then squeeze against the wall causing extra friction and heat. That will turn in to seizing the engine.
So I purchased a ring grinder set up
20240128_172441.jpg

Place the ring on top and give it a few turns on the wheel. Then remeasure . Your better of bit by bit and getting it right. Thats taking to much off and then having to source new rings.
20240128_172111.jpg

So top ring has to be .04mm 2nd ring .045 and then.oil scraper .04 mm. Its very time consuming.
20240128_172022.jpg
But keep each set marked to what bore you set them up in. So it will all be purfect.

Next up..... New forge motorsport sump.
20240128_101615.jpg
some lovely welding holding in the baffel plates.
20240128_101619.jpg

Even labeled up to show who made it and who checked it too
20240128_101631.jpg

Even has the oil level sensor hole.
20240128_101634.jpg

But I won't be using that so they even supply a forge blanking plate with stainless screws
20240128_102405.jpg
And to be on the safe side to help monitor the heat threw the engine. I have some stick on temp gauges. They only work and stay at the max temp they went to.
20240128_102413.jpg

So if it goes bang I can see how hot different areas of the engine got

Need to change the oil pump gear on the crank. As I am going to be using a 2.0TFSi crank. The tfsi is different to the 1.8t gear
20240201_145021.jpg
the TFSI (totally F ing stupid idea) gear is smaller. So using a small puller I put a bolt in the end of the crank for some where for the puller to press against
IMG-20240201-WA0014.jpeg
Then with a little heat from the oxyaccetalyne gun and the milwaukee 1/2 gun
IMG-20240201-WA0001.jpeg
the old one came off.
With the new gear in the oven waming up to expand it . I cleaned the crank shaft. I then held it in a vice with cloths in the gaws to not damage the crank. The new gear slipped over the top. With a large socket I held it down till it called and contracted
20240201_154157.jpg

All done and cleaned
20240201_154154.jpg

So then gave all the oil wats a blow threw with the air gun. Then coated it in oil and wrapped it up and in a plastic bag to bring it home

Bugger. I thought I had written some thing but I hadn't. I would like to say a massive thank you to. https://decimaltenths.co.uk/
A lot of the information ,ideas,specs and even down to the tolerances to run in side the engine has come from thier youtube videos. Starting with this one.
If your going to build a stroker, even just curious about it , or just love watching people build stuff to a high spec and tolerances with how it is done. I can highly recommend to watch thier channel. Thanks again decimal tenths

TOP SECRET.... I have been asked not to share these. But they too good not to show .
Drum roll....... I am having billet oil filter housing made. With extra ports for oil cooler . So no need for the sandwich plate. Should be finalised in next couple of months fingers crossed

This is lovely machineing. . Love the finish on this... I will post more details when I have it in my hands

Mr postman came today..... Nice bit of heat management from funk motorsport.
20240210_132940.jpg
20240210_133019.jpg

The idea is to keep the heat in the turbo and exhaust system and not in the engine bay. Keep the engine cool.
So to stat with... a baby little blanket for the waste gate
20240210_132954.jpg
20240210_132954.jpg
20240210_132958.jpg
20240210_133005.jpg

These are hand made . I went for the titanium finish. Ad much as I love carbon fibre. I think the titainium finish will have a nicer look under the bonnet. Then we have the bigger blanket for the hot side of the turbo
20240210_133033.jpg
20240210_133036.jpg
20240210_133040.jpg

All are multilayer insulated and with a fine wire mesh around the edge keeping the blanket all together. And they sell off the shelf. For all applications .

As most good times start with lube....
20240210_174556.jpg

Clean and cleaned the block and refitted the main end capthen a covering of the lucks assembly lube. This stuff is like thick gearbox oil and stringy
20240210_174546.jpg
20240210_174543.jpg

Then after having fitted the new oil pump drive gear
20240210_174539.jpg

I have also changed the timing pick ring.
20240210_174537.jpg
Using new screws and a little loctite. .now ready
20240210_174533.jpg
gently lower the crank in to position and spin over
20240210_174853.jpg
screw in the arp main end studs. Clean the billet caps and fit the AVL race bearing . Slide on and seat the caps over the crank then tighten threw steps. 20lbs,40lbs then 60lbs
20240210_175121.jpg

Just line up the high flow oil pump
