that sounds more like it 
i still have to look into all this,id like to get the tb set up but just use standard cams and everything else.
see what parts i need and maybe find some 2nd hand or ..still will cost a fortune but im sure it will be worth it in the end.

Shouldnt be far from 175bhp with bodies. A decent exhaust would help.
The manifold is 42mm and most people go too big on bodies so 42mm made sense. According to the Jenvey website 42mm is enough for 224bhp. Plenty enough for me.
Ultimately I would like to change to proper ITBs rather than these twin bodies. Then I'd be able to use the straighter inlet manifold as I'll be removing the PAS pump.

Quite right. Really high revs can live with short inlet tract. Cars don't rev that high though hence the need for fitting longer bodies for my car.

what's the differences between proper ITB and twin bodies???

Twin bodies are like DCOE carbs. They are a fix distance apart and each body has two inlets. They might not necessary match the port spacing of the cylinder head.
True ITBs are just that...independent of each other. These can be fitted to a manifold so the run into the ports on the head is arrow straight.

so is that in theory if both are port matched it should give the same performance?

I'm Intrested to see how your fan mod turns out have started yet? Nice choice on the filter Are you going for a megga deep filter or a deep back plate/box like mine?

Looked at the filters with the carbon box but the box alone is about £90. Even with the deep 125mm (internal height) the filter and backplate are about £130.
Stripped it down a bit more today. I might end up moving the horn elsewhere to make more space for the radiator. Also thinking about running a hose across the bottom of the engine bay so the radiator inlet and outlet can be at opposite ends. The radiator will sit further forward than standard meaning there's more room for a hose at the back.

A man of your skills will cut that lower Xmember off and lower it a shade.... the bumper will still cover it.... then you just need to modify the top mount.
You are at the stage where I was a year ago and ended up chopping it to bits and making my own with the toyota radiator.
Nice to see you still modding though

That cross member is staying where it is. That's proving the lower mount for the new radiator. You can see the rubber bushes that will hold the bottom of the radiator.
When I get the air filter that will show me what to cut off the original fan housing. I'll only be keeping the top 3" or 4" of it. That might give me something to hold the top of the radiator and also means I can use the standard bonnet latch.
I'm also hoping the standard PAS steering hose (the metal bit) will screw into a Saxo/106 PAS pump. They look quite similar. I can re-use the metal pipe and get a hose connected to it.

I have made up rubber hydraulic pipes on the rally car but it boils the oil too easily. I now have an oil cooler in the return line

Yer my carbon box was around that 2bh mate, the Jenvey filter I have is made by pipercross any ways as it's stamped on the inside lol.
I can see what you are doing now regarding the top part of the rad cowling I'm just using the upper grill to channel cold air direct into the inlet
Yer the metal bit fits fine as they used it on mine Paul see pic as for the conversion IMO I think that the feel is more positive and a better feel I also think it seems a bit lighter than the standard belt system.
