i had also consulted Akber Sahab (Metaltoppro) and he gave me and estimate of 250k(engine overhaul not included) for a new turbo with intercooler, new front suspension, rear bearings, new differential and new engine seals. But i feel that the engine has excessive blowby(back in local terminology) so it will also need overhauling (regular mechanic gave an estimate of 60k).
