How laggy will sc46 be on a 2005sti as i have the chance of one

 

i dont think it would be laggy at all,its a very good turbo as i spoke to my mapper about the sc46.go for it mate.

 

I built and fitted a new engine for a 2005 STI early this year, it had an sc46 fitted and it wasn't bad at all for a big turbo.

 

I have a what was supposed to be td05-20g on just now but it doesnt make 1bar of boost till 3700rpm guy i use says the exhaust housing is bigger more like td06

 

I have a SC46 Billet on my 03 STI and its not bad at all. It has more lag than my VF34 but thats expected, 1.5 bar @ 4.5k, 1.6 @ 5k

 

Well I'm only running my car in .7 bar by 3000rpm and 2.0 Sti 4 heads spools up nicely will be even better when I'm running 2 bar haha !!!! Only got 100 miles till its run in then mapping !!!! So I'll keep u informed Mine is the billet one.

 

If lag is your worry, get the "twin-scroll billet" version.

 

Ok cheers guys

 

I would go on 2.0L with SC42 or MDX321T

46 wont be laggy on a 2.0ltr with avcs, but of course it depends who maps it and your supporting mods

 

Will be andy f mapping and mods so far
Ported headers/uppipe
Full 3"decat
650cc injectors
Hrc fuel pump

 

should be fine, i was on syvecs and had a front mount too

 

Have you considered the smaller younger brother of the SC46? The SC42?

Slightly smaller so will give less power than the SC46, but slightly quicker spool, thats what Scoobyclinic told me, and thats what I went for, its great with no more noticeable lag than the orginal VF35.

 

Its just that the 46 has come up for £800 and its only been on for months im running 396bhp 370ft/lbs torque

 

I was going for the sc46 but scoobyclinic told me I would be a lot happier with the sc42 for a road car. My car makes full boost around 3700rpm.

 

I'm running the 46 and am very happy with it , 1.8 bar @ @ 5.5 k and holds lovely , hitting 1.3 by 3.5-4k

Had the 42 for a short while and was slightly quicker spool but just a bit down on the power I was looking for at the time .

 

You wont be disappointed with a 46 mate

 

had a 46 0n my 2.5 with just forged pistons and uprated bearings

was great for low down torque, and pulled hard. loved it at the time. sure it peaked at 1.4bar down to 1.35 but put a grin on my smiler everytime. couldnt fault it atall

 

Its the billet version will that help

 

That's what I've got mate

 

anyone have a dyno graph of the sc42 v's sc46 on a 2.0ltr newage?

 

I get my mate to post up my graph, I'm awful on computers!

 

Cheers ken

 

Got a billet twin scroll one on mine goes very well indeed on a 2.0 and mines only mapped up to 1.65 bar.

 

What power did yours make at 1.8 bar?

 

ken's SC42


all you need

Cheers Wiley!

 

Is that really a 42 & not a 46? I didn't think they could make that sort of power.

It's a billet sc42. I'm well amazed with it too! Can't go wrong with these turbos!
