whos done big turbo conversion on st?

[Adamski]

The ST turbo/manifold flange can be opened out so no need to swop

oh yes but there only £20-30 so no real biggy i'd rather have a oe than bore it out

True

You need to use the BT sensors too,

The BT coolant temp sensor will require a threaded adaptor if you are going to use it in the ST head.

engine will stay st, not changing heads or anything

why carnt i use the st sensor?

[cosmo]

LT has a different size thread to the ST one.

ST sensors are dedicated for EECIV and will not work with Weber ECU's.

They will however work with aftermarket ECU's

Mark King has recently coverted his to BT

[Carlo]

you need to tap into the small turbo inlet for the brown sensor

Yup thats another. (Air temp sensor)

or extend the wiring if keeping the same position.

[richyx]

ok just spoke to someone who has gave me some more info and is what you guys have said

so when the time comes ill tap the inlet for charge sensor and will get an boss to fit into the head to fit the water temp sensor, the rest should be straight forward then

doesn't sound too much work then, I've not heard of anyone going back to ST after the conversion though.

did you do your craig didnt know your was a st

[iain]

craigs was different he was running a BT head and inlet so he didnt need to change anything and instead of joining in a saph 4x4 loom he changed the whole loom to an escos big turbo loom...im planning on doing this threw the winter aswell richy iv started collecting bits got a l8, siemens and a bottom pulley so far.. think im going to run a swedish plenum instead off having to tap in as i like the look of a swedish lol and run wasted spark as my small turbo rev counter should still work i think

As Iain has said above sums it up how i did mine (well paid sparkys to do it for me)
