The brake servo hose goes to the one at the back of the inlet and the one under the TB has the oil breather pipe going to it.

they have a tiny amount of 'slack' yes.

With the same tool you've mentioned. We're arm wrestling next time we meet........

If your not planning on making too much extra power then it'd be an 'easy' solution i guess.

Just check you've got the right tools as a conventional angle gauge on the ex pulley nut is virtually impossible. And completely degrease all the pulleys before they go back on.

If we consider elements of 'boost' as a constant (effective density), then effective conversion of boost to work done is the result of the thermal efficiency of the engine, not of the turbo system itself. If we are talking about the efficiency of the turbo system itself, simply due to the...

Its a dumb design, but if the lower torx is tight then when you put the 3/8" square to de-tension the belt, it can nip up and hold the assembly in the de-tensioned state. You would of thought the spring would pivot on a bush rather than the bolt itself, but hey ho.

True, but efficiency excites me. But at least we've come to the root of the arguments lol.

Ah right........thanks. I mean there is some arguement, but i'm unsure what it is about. I thought it was about the pros/cons of rear positioning, but you informed me it wasn't.

did you tighten the lower male torx bolt holding the tensioner spring to the idler body?

I am really failing to see the arguement to all this? Who and what is actually being discussed.

success isnt a it works/doesnt work issue. If you have a wart on your hand, is amputation of the entire limb considered a successful cure? Fact is that mounting a turbo in that position is highly inefficient, even if it does make more power than the stock engine would. If the turbo was...

oh sorry......right, the mag.

You loose a LOT of energy by the time exhaust gasses reach the rear of the car....its an inefficient way to run a turbo.

RIght behind the oil filler.........cylindrical solenoid with a plug going into it.

Its the solenoid right next to the oil filler neck. Single 10mm bolt holding it into the centre of the cam cover on the offside.

lol yes.....apart from that.

Just remember the crank tool doesnt slot into the crank IIRC, it rests on a lip so the crank can still move counter clockwise...highly irritating. Its stupid.

Ben....you've jsut splashed out on a new engine. Just remember you get what you pay for..............step away from halfords.

They both run helical diffs, so same idea as the ATB.....which is certainly better than a stock open diff....but seriously, get into a car with a properly setup plate diff and you'll see why nobody wins races with helical diffs. ATB's in my experience understeed like hell and dont work well...

Stans got it. Boost is boost when your simply looking at it from an absolute level in the inlet manifold, but when you apply the dynamics of a working engine system, it means very little. Even assuming the relative corrected air density is exactly the same, the actual mass of air...

Agree. My flow bench doesnt do much more than collect dust anymore. You'll soon find out that massively good flowing heads result in lost performance on an engine. However 3d realisation in conjunction with flow testing and a minds eye can tell you if its any good or not.

Damn straight you should.....it freaking rocks! ATB's are pants, dont waste your time as stan said already. If your going LSD...for a FWD that needs to be used in the twisies (not drag) then an aggressive plate diff setup makes a world of diff. Hope your ok stan.......falling off 2...

Things have moved on significantly since then. There is zero point polishing anything or matching the head to the gaskets.

Simply put, the 172 head has its own massive flaw in port design, but because it is CNC machined, this leaves you very very little in the way of rectifying the flaws. So 'typical' porting methods can only gain a finite amount because you simply do not have the material available to work in...

plenty....depends how deep your pockets are.

phs1 will fit yes, and it does flow significantly more on the exhaust port, but you have to quantifiy if its needed or not. Bulk flow rates mean very very little in the grand scheme of things. AS for bigger valves, just because they are bigger again doesnt mean more flow. In the F4R you have...

Bigger valves provide zero benefit at your level.

There are A LOT of stupid people around though. So if it stops a woman crossing over into my lane on a wet day...then yes its needed.
