Iam trying to improve the performance of my cab and have in mind a manifold and throttle body. I already have a reflex back box. I figured there may be some wisdom here. Any advice on consequential mods and set up?
Thanks

as stan says you should get quite a decent gain from it, considered fitting the exhaust manifold and cams ? also worth doing. not very expensive either!

the exhaust will also require a gti-6 downpipe/cat as well. the inlet should be a straight swap, as with the cams (though the timing may need perfecting, something I don't know about... yet). both the inlet and exhaust manifolds will see a decent gain, as these are VERY restrictive on the 1.8.

will be interesting to see the results if someone does do this, as these engines are common as muck, can be picked up for a few notes.

quick update, just done this swap on mine. The XS stepper motor doesn't fit without a fair bit of grinding/drilling/filing to make the bolt holes line up and fit. Also some of the A/C pipes coming out of the pump may get in the way (my a/c is shafted anyways so I just 'encouraged' the pipes to sit a more convenient location). And yes, some of the sensor wires will need lengthening.

for me at the moment it's not running right, so I can't say.

To add to my previous post, you'll also need GTi-6 fuel rail and stepper motor housing (on the xs the stepper mounts directly to the TB, but on the 6 it has a seperate housing and air feed). also you need to swap the sensor from underneath the xs manifold (inlet pressure sensor?) for the similar one on top of the GTi manifold, as the connections are different (it's only 1 bolt to swap, both are3 pin but the xs one is smaller), the injector loom and some of the sensor loom around the TB neds to be free'd up from the rest of the loom otherwise it won't reach (yellow 2pin tps plug and white 3pin something plug), and the manifold fouls the radiator top hose without some persuasion (I removed the forward of the 2 clamps holding the arm on, but make sure to put the bolt back afterwards, as it also holds the gearbox on). Finally, some of the breather system hoses need modifying as well, so having a set of GTi hoses would be handy (particularly the ones from the rocker cover to the tb/inlet).

the xs fuel rail can be made to fit, but it requires the mounts shortening and some L shaped brackets carefully fabricating to clamp the rail down, though it'd be a lot easier to swap for a 6 rail instead if you have one.

you ned a GTi cat, but otherwise it'll go stright on if you can fit it in there. I've not tried to put mine on yet as I'm told its a head off job.

To put the exhaust manifold on, you have to take the engine mounts off, pull the engine forward, try and hold it forward some how, maybe a wedge, then try and put the manifold on.

Exhaust manifold and cat pipe going on on friday night next week-Tim, "the wrench" is confident and thinks it will go with some wrestling. my other car may be useful over the weekend.....
He is working in his time but his employers shop/lift etc. I will be at hand to buy Red Bull and pizza!!!

As said the 6 exhaust manifolds fit with ease with the subframe off, you may need to adjust the rear water dist pipes depending on there routing
