Right then i have just quickly converted the Nm figure to torque, to show the actual torque figures as in my eyes it is a good torque curve but the graph makes it look short and peaky when its down to the torque peaking so high in the 1st place.

As can be seen i have a minimum of 260lb/ft between 3000rpm > 6000rpm, now at 2500rpm its 166lb/ft which is the same as a G Lader peak torque and quite close to a pullied, chipped and flowed charger, and right on the limiter its still doing more than the previously mentioned set up. For the torque to double in 1000rpm between 2500rpm > 3500rpm as it comes on boost you can imagine the problems i have with traction in 1st and 2nd Smile hence why i need longer gearing and quite possibly i may be trying the CTN as a cheap alternative to the VR6 set up, i think i have made my mind up.

RPM = lb/ft
2500 = 166
3000 = 258
3500 = 317
4000 = 332
4500 = 339
5000 = 317
5500 = 291
6000 = 258
6500 = 239

On the 2 seperate graphs with red lines they are the same dyno run from my engine, just shows you how different they can look to the eye as in the 2nd graph it looks like it has more torque for longer compared to the 1st graph even though they are identical runs.

So again Green line is torque, Black line is BHP

So when do you expect to have it back on the road, Si? Are you going for the cross-flow head as well?

Well the new parts have arrived, the new exhaust manifold looks and feels loads better, not offered it up to the old 1 yet to see the differences and what i need to modify to fit it so hopefully shall see at the weekend.

The cross flow is on the back burner for now, when i put it into a mk1 race car then i shall do it then i think.

Got any pics of the two manifolds side by side? Was the original manifold a Jabba one?

I still think you should fit a cross-flow head. As the one you've got is off, why not?

No pics the other is in the garage, they are both Jabba manifolds but 2 different designs.

Yes the head is off but i need to source a new crossflow head, big valve it, cam it etc, modify 1 of the waterways or oil i cant remember what exactly, new pipework, new custom inlet manifold, the list goes on tbh, i dont have the money for it yet.

So hopefully getting the mk1 after crimbo if the guy sells it me, [mk1 GTI Campaign '83] then concentrate on doing it then as it will be a full on track car and the bare minimum road legalness.

Ah, I see! Bloody hell though, your engine in a mk1! That WILL be fun.

So the cross-flow head isn't just a straight swap then? I was under the impression it dropped straight on to the PG block. I realise that you'd need new inlet and pipework etc.

As far as i know it will drop straight on with the aforementioned modification, as far as i know its simple to do it just needs welding up then figuring out the gaskets.

Yea it should be bloody awesome hopefully, literally everything stripped dash the lot, think like BIG DUB style, weld in cage [which i think is a must], stiffen the old chassis nicely for the power and the safety net it will give. hahaha

If its still going ahead then its April's calendar pic too.

Right then had a couple of days getting it back together and its officially fixed to the point where the actual broken bit is on lol, managed to get the inlet/exhaust manifolds back on with turbo and wastegate actuator, waiting for correct head gasket to arrive then the work continues.

So the exhaust manifold needed modifying, basically its been designed to be the manifold for the turbo diesel conversion they do as well as fit the G60, so the turbo mounting flange is a different shape now which means 1 inlet manifold will not fit, dremel'd down to clear, plenty of metal to remove safely, just required a notch taking out. Also the studs to mount the turbo needed shortening to clear the downpipe and to bolt down tight.

It's getting there albeit slowly but time is on my side fortunatly, and what a bloody good day it's been today.

do your wheels have a dish, Si? Or are they kinda all the same face? If so, why not go body colour on the centres?

Not enough of a dish tbh and if they had stepped dish then it would make the centre smaller so it would then look ok to go body coloured but im not into that i just want it to look mean and track inspired.

I want BBS CH's in the black they do but they only come in 18" but i can get the CH's in 17" in silver but im not sure if they are a 4 x 100 fitment.

Veeeeeeery slowly still, got the head in position on the block and bolts in, just needs torqing up now, bought a torque wrench but been waiting to get my van back as the 12 point socket was in it, basically just got the van back today.

I was on the motorway, 85mph, Mercedes Vito by the way, long wheelbase, new style. Heard a little pop and lost power, pulled up and saw loads of white smoke bellowing out the exhaust, turned ignition off, key out and engine is still running, called fire brigade as i carry loads of gas on the van, they turned up really quickly, no fire thankfully, engine ran for a good 5 min then cut out on its own just as thay were popping the bonnet, anyway, picked it up tonight, new turbo, intercooler, cylinder head, head gasket which they repair apparently, it gets sent off to be done with a 5 working day turnaround, asked how much for the lot and she was sheepish in telling me, but she said it begins with a 2 and has 4 numbers in it lol.

So waiting for a break in the weather to crack on some more now i have the tools again.

I the head gasket goes on a diesel and its the oil that gets in the cylinder, it will run on it's own with no diesel pirat

Yea basically running on the oil i think.

The recovery guy said the engines are not even Mercedes in the \vito but are in the Sprinters, sure he said they are Toyota engines in them, they also have an IHI turbo on them, a piddly little VF14 on the long wheelbase and a VF13 on the short version.

Its a lease van anyway through my work and i think covered under the warranty still, we have to change vans every 3 years and its due Jan/Feb 2009, its just under 54K now, but on the brightside its a lot more perkier than before, i think it was on its way out for a good 10K TBH.

Gotta love turbos CTW lol.....Are you sure you dont want to convert?

Maybe you should just use a push bike simon.The car thing just aint working out for you.
Anyway get that head torqued up and stop waffling.

You must be dying to drive it after all this time?!?!!
So you have everything you need now?
So the mark1 is going to be the new project car and the raddo is going to stay in 8vt mode?

Yeah I thought that was called deiseling?

Our TD5 Landrover had its turbot let go, and took itself up to redline very quickly after. Luckily they managed to stall it in time.

I moved onto cars as the pushbike thing wasnt working either, used to kill them too lol..

Im actually not that bothered at the moment not been for a long long while, its done when its done basically.

Not sure what direction to go with the cars, i think my engine in a MK1 [which i dont have yet] would be enough and mucho fun, then to put a 20v in my Corrado with factory management etc. See how things go, need to get a MK1 strip it, race prep it cage etc, with the minimum amount of road leagl requirements then go from there engine wise. Get that all sorted then i have a fun car whilst i make the Corrado my ultimate project.
