This is the complete setup ...will caused around 10K dude...
exactly! then again, there is no compromise in reliability when it comes to bot'ing a na engine. even more on sohc 4g18p.
just sharing my experience, when i was just into car stuff, a friend of mine bot his 4g18(1st generation waja). boosting at low 0.6 bar,
his piston head crack and there was a leakage on the gasket.
for na engine with bot, reliability over performance comes into consideration. but for factory fitted turbo engine, you could have both

rough cost for the bold item? breakdown would be nice... also how do you suggest we source this item.. anyone to recommend? some half cut fella or workshop
not include twin pot of coz.. this i know the price d

should be more than 4k to be consider as close to proper bot with most expensive one goes to piggyback management chip.
be careful of imitation part. perhaps, steven could elaborate more since he is using bot.
there is one half cut trader in mudah site. under the trader name ayie from puchong but his price are quite steep. perhaps, cheaper if buying in bulk.
any garage in sunway could do the job just fine.
also, pcd114.3 of older evo brake might not fit straight into waja. either re-drill of rotor disc or knuckle change require.
for the dual layer brake servo, only those from evo 6.5 can be consider as plug and play to 4g18p. evo 3 and below will not be a straight job, while evo 4 need
minor modification.
4 pots from nissan rb series is another option.

Guys.. i got one question..
If you dont run a wastegate, means when you drive you become a manual boost controller (your right leg)?? Is that right?
almost similar but not there. without the wastegate, you need to be very very light on your right foot / lower than 0.6bar boost which in turn kill the fun of having a turbo installed

.
as far as i know, wastegate act as a proper boost regulator management. without the wastegate, excessive gas might not be channel out properly to exhaust system. also, no proper regulator for the turbine. this effect the turbo effectiveness(sticky) and engine in the long run.
