Default What Power?

I'm considering going down the 2.0 / larger turbo route, but without too much lag if possible.

I've got a 2.0 STI Blobeye which I plan on a remap on 15-20% methanol with a SC46, and maybe billeted at that. The rest of the car will be supported, but what type of power should I expect?

I'm hoping to get well over 450. I plan on getting as close to 500 as possible, but I don't want it to be too undriveably laggy.

Thoughts please

Oh and why an SC46 you may ask, because I've already got one.

People need to stop worrying about lag, you xar at 450bhp will never be as nippy as a 300bhp tdo4 car but the difference in power delivery will be amazing.


Thee good thing with gears is you can change down and be instantly on boost.

My car will be laggy compared to some low bhp cars but if I was to drop it into 2nd/3rd gear and floor it its

I'd be happy with that, but with meth on a 2.0 with avcs I was hoping to rekindle the lost spool, and ultimately push the turbo as much as possible. There doesn't seem much info about the SC46 on here, so it's hard to judge its capabilities. SC state it's sold as 460 with the billet wheel.

Non bud, but I was thinking of getting billeted, to help increase spool and power

Excellent, this is good to know. I take it your T is billeted? The SC and MD are very similar arnt they?

Your right Steve, but too much lag isn't good for anyone. Your always reducing spool when you make the wheel larger, it's factual. But I couldn't drive a car with 500bhp if it didn't come in until 4'500-5'000rpm. I've bad GT30 on a 2.0 bug at 430bhp in the past and it was a little laggy in comparison to the 2.1 500bhp classic I had. I know weight is a factor, but a billet makes such a big difference.

What you could get does not mean you will get it.

Meth does not alter spool.

I run a 46 billet on a 2ltr and running 429/380 but it is a little laggy, Its lazy until 4500/5000 when it takes off.

While the car is off the road this winter i am planning on trying to reduce the lag.

Crickey that is a bit on the late side. Must feel rather neck snapping when it kicks in.
What does something with this sort of power drive like on a back road?

It's that on standard internals ?

The reason I ask is that,I've got a UK 05 STi, I'm thinking about going for 400bhp with matching torque.I know I've got to change the turbo etc,but I'm concerned if the internals will handle that mount of power without melting.

IT will never be that laggy unless you really have problems as I run high 600's and I see full boost at around 3600rpm. I know from the warnings on my dash I'm at 2.3bar well before 4000rpm

The turbo he was on about Craig that's why I posted.

Sc46
Meth adds torque though Shaun and that adds real word performance
Numbers are at the end of the day just numbers .

An STI MY01-MY05 2.0 will see 400 on standard internals for fun

In my v2 Sti Ra with the baby td05 there actually is pretty much no lag. The gearbox means the revs are generally high and constantly on boost. What gearbox are you running Rob Day?
