Possibly, I'll see what I can get with the existing turbo, it's easily good for an extra 0.5 bar of boost (I've currently got about 200bhp ... 1/3 more boost = 1/3 more air = 1/3 more fuel = 1/3 more power = 266 bhp
) ... but if/when it breaks I'll put on a bigger one
are you running 1 bar boost now? then another 0.5 bar will only give you 25% extra air, provided you can keep the intake temps the same.... 1 bar atmospheric pressure + 1 bar boost = 2 bar, remember?
What engine do you have exactly? and are you sure you're not already running higher boost?
I was going for the same upgrades on my 136 bhp jtd, but I wrecked it last week. nevertheless, I expected to top out somewhere around 220-240 bhp because the fuel pump would be the limit.
Here's what I reckon I needed:
- Turbo (I fitted a GT2256V from a 175 BHP m-jet)
- Euro3 injectors
- boost controller (you only need this with the 136 bhp)
- better downpipe from turbo
- proper remap
- Bigger MAF
I was nearly there aswell, had sourced a GTA MAF housing and an enclosed cone filter (jr airbox) and the boost controller... just needed the euro3 injectors fitting (which I have aswell) and a proper remap
