Sc40 or the 42 would be a good option

Not really looking for extra power just wanting better spool up and low down grunt as mines maxed now

Hi there

Really better spool up as you have already good with yours then I would have look on the SC36,which should be great on the yours if you are not looking for extra power

If extra power is required then SC42 or MDX321H or MDX321T should be awesome choice too

Thanks for the reply Jura,some reason I'm getting any notification's so only just seen this.
The sc range were what I was looking at really,so you would suggest I go for one of these ?
Might have to do a little research and work out what's best for my needs.
If I were to go with a sc42 what other mods would I need to make the best of the turbo ?
And what power would the sc36 be good up to?
Thanks Jon

It's all in the title of there turbos but they are being conservative,for example SC36 360bhp,SC42 420bhp and so on.SJ.

I did think that,thanks for confirming mate,any offer mods needed if I were to look at sc40/sc42 ?

You seem to have all that is required really maybe some bigger injectors if you are still on the standard STI 550cc ones but really you should be fine,have you done other mods for example beef up your stopping power and suspension components etc...because tho whole modding of a car has adverse effects on the remaining standard parts as?SJ.

SC40/42 will hurt you lag wise, particularly if you are actually looking for better spool.

Yeah you seem to have taken good attention to that part as wellcan recommend performance friction pads Z rated or 08 compound which is more fast road track orientated or even the Carbone Lorraine RC5+ Which I have driven with and seem to like them more and more,but my personal preference would always be the PF pads.SJ.

Hi Jon

As above SJ said,SC36 is 360bhp,SC42 is 420bhp turbo and in MDX range is slightly more confusing like H is 400bhp,T is 450bhp turbo

Other mods what I would suggest,really depends what turbo you are looking to run,as you already running FMIC and other bits,then I would go probably with SC42 or MDX321H,those turbo will make nice numbers on yours with reasonable spool

If you will go with above mentioned turbo,you will need to have bigger injectors,650cc should be enough,if you are not looking to run methanol,but still think with 650cc you should be OK to run methanol with reasonable IDC,just what I would suggest too is add Fuelab FPR
