Default big turbo conversion

Just out of Interest, if sourcing the parts secondhand where appropriate. what would the cost be for this conversion. Just a rough idea please and what parts are required, obviously the turbo...

I used to have a stage 3 Saff, now I have the small turbo Esc....im not sure which is best, the sapphire pulled like a train, but there was the lag....escort is fun and instant...

anyway....whose going to write me a shopping list...

If you have ac the bottom pully of a sierra/lt esc cos, the ac belt for the ac isw single v not multi v like on the st esc cos. Also exhasut manifold is slightly larger on a large turbo where the turbo bolts on to manifold, but standard one can be machined.

Inlet manifold
Throttle body
Throttle switch
Front pulley from big turbo model
TDC sensor and bracket
Coolant sensor & adaptor
Air temp sensor
Idle valve
Conversion plug leads
Grp A head gasket
T34 turbo
Exh housing
3-bar map sensor
injectors

I think it would be cheaper to buy a big Turbo model...and have it sprayed Auralis....

thats sound like a £2k job to me....
