wahh u want repsonse, lesser lag, planning to boost around 1.3 to 1.4 but only talk about turbo ??
got other stuff to look into la besides turbo la dude
i am guessing u r using a 4g63 engine. but dunno which model.
so i am assuming u r using evo1-3 la. actually all the same one.but here are some cheap alternative that can push ur evo/vr4 engine horsepower to 300hp++
1.change block to vr4 rs
2.change to oversize throttle body (>64mm)
3. change injector (>510cc)
4.twin blade td05h (ask tong to hybrid 20g and above)
5.metal gasket (1.5mm also enough)
6. wastegate(very important if u boost high >1.2 bar)
7.block evo3
8.coat ur piston with ceramic (normally done in australia)
9.use haltech management
10.
most people dunno that vr4 engine can boost higher than evo engine due to thicker block. but the problem with vr4 is that it has heavy internals.
thats why if u hybrid evo head with vr4 block and use ceramic coated piston(which can stand very high temperature and thus higher boost), u can even go higher than 1.7 bar. confirm
mirage intake manifold has same length as vr4 but it is shorter in length. air flow is quicker.
change also the turbo to 20g la. tong very pro in turbo modification.i recommend him gile2.if got extra money then go for ball bearing garret la. but i would suggest u hybrid only. the garret turbo mostly cost rm4000 at N1. crazy man!!
metal gasket is also very important for higher boost.
once u go for 1.2 bar and above, u have to have external wastegate(above 45mm ok already).

i want response,lesser lag.planning to boost around 1.3 to 1.4 bar.
because i heard someone mod their stock turbo like changing fin and so on.just wanna know what modification can be done and is it advisable.
