Td05-20g
Ported headers and uppipe

But how does it spool compared to mine would rather drop to say sc38 for quicker spool than go sc42 for what i already have

Tidgy

depends what power you want chap. sc42 will outspool the 20g and do the top end numbers.

Best bet give kev at clinic a bell and tell him the application and he will be able to tell you what is best for what you want, sure they can advise on best spool/power.

During which circumstances are you suffering lag ?
Cruising along in 5th at 40mph ???

I run with a 20g and dont find it laggy at all, just be in the right gear

Is that a 2ltr?
What other mods you running pal?

peter zippy reid

iTrader: (25)

Yes say sitting in 4th about 2500rpm put the foot down and nothing till about 3700rpm then it kicks in andy f said when he mapped it he thought it was coming on late but making the results once it does

i didn,t noticed any when you took me out and i was expecting some

apparently the sc38 spools alittle better than the sc42, although don't think theres much in them to be honest. sc42 more power top end ofcourse but you can't fault the sc38.

One of the reasons sc removed the sc40 as the sc38 was generating similiar sort of power of the sc40. Depends what you want mate. Looking at your supporting mods, you have uprated injectors, have a induction, 3" exhaust and if you are after big power then sc42 will be suited for you but so would the sc38

Yes on a newage 2ltr, FMIC, decat exhaust, air filter, EL manifold and upipe

That pretty impressive ive been thinking about getting a sc38 but dont fancy paying new price but finding a 2nd hand 1 seems to almost on impossible

Tidgy

same with most of the billets lol

Put it in third then put your foot down.

I really dont understand this lag talk, if your in the correct gear then it wont be laggy at all.

MattyB1983

iTrader: (51)

Nope, none at all buddy because I keep the revs up by being in the correct gear.
Any turbo will create lag if your in too higher gear.

barnshaw

iTrader: (1)

its not just about being in the right gear though, for example you might not be hitting 1 bar until 4500 rpm but then on a billet turbo making same power your hitting it at 3200rpm, that means you get more power through the rev range which is useable.

MattyB1983

iTrader: (51)

With my 20g im at 1 bar boost by 3100rpm.

peter zippy reid

iTrader: (25)

I dont hit 1bar till 3800rpm thats what andy f means by it comes on late

MattyB1983

iTrader: (51)

Where did the turbo come from ?

Did he give any advice as to why its not making boost earlier ?

peter zippy reid

iTrader: (25)

Bought it from a member andy seems to think it might be td06-20g but im not sure heres pics when i bought it

The Gaffer

Hi,

one previous owner, Fred dibner.

Sc38 Billet will do your job nicely, in stock at £975.00 + vat and come with new water pipes, oil return and gaskets.

cheers

If its a td06 then youve answered your own question. Commonly known to produce boost later in the rev range.
I wouldn't be able to tell the difference but if Andy suspects its an 06 then it more than likely is

peter zippy reid

iTrader: (25)

Cheers kev will be in touch in the next couple of weeks

peter zippy reid

iTrader: (25)

Thanks for all the help matty think my turbo would be more suited to 2.5

Matty he have TD06-20G and those TD06-20G are laggy on 2.0L,on his 2.0L STi TD05-20G will perform much better than this one for sure

SC42 looking like good buy and should perform nice on yours,but would suggest have look for 3 bolt headers GT Spec or WMS headers

Second option is go with MD321 Billet
