Power is nothing without control, first port of call would have to be sorting a decent ecu and syvecs S6 is ideal for what your looking for as Jura has said.

Back to the original question you are going to need to rotate the turbo for better flow of gases and along with most I suggest a gt35 aswell, that said a well supported gt30 with RCM hybrid intercooler/rad would compliment your already in place cosworth manifold resulting in very little lag.

Head work depending on what's already been done supertech valve train is the way with some cosworth cams to suit.

Hi there

30R with 82AR should be making close to 600bhp,we are made on GT30 .63AR 555.5bhp at V-Power

Yes 35R will be and is better choice for 600bhp if you are aiming for 600bhp

HTA are great turbo,but they're not cheap and still if I would go again with turbo then Borg Warner EFR I would choose,they're similarly priced,but EFR range spools much better

If spools what matter most then 30R with 82AR or 35R with 63AR

Thanks,Jura

Hi there

MDX321V will not make 600bhp on V-power alone,yes maybe close,what I've seen on V-power and meth this turbo making around 550bhp,seen few at 560-570bhp region

Thanks,Jura

Hi there

Billet 30R with 63AR exhaust housing should make around 550bhp,with .82AR I would say close to 580bhp,but I've seen few which has making 600bhp on V-power alone

Thanks,Jura

Hello mate,

What part of Enfield are you in?

I'm a stone throw away, and met some guys who were originally in Enfield, but moved to Canning town, near Stratford.

I was at their garage over the weekend, they had 700bhp Evo's and scoobies there. They used to get their cars mapped at Zen, and Paul from Zen said their big power cars were put together well.

I'll PM you their phone number, your best off going down to see them for a chat. They'll give you good advice. They are really nice guys too.

They had 6 scoobies in when I was there on Saturday, as well as a load of other nodded Jap cars.

Nobody has mentioned that the garrett 'X' range of turbo's produce more power for the same old equivalent size.
i.e. GT3076R Vs GTX3076R. the X spools faster and produces more top end power....

I don't believe head work is essential, but it depends on the heads you are using.
A well known tuner stated that small port avcs heads work better than large port up to around 600bhp. Unfortunately he is no longer with us :-(

GT30 82AR 580hp at what bar boost?

jura11

iTrader: (7)

Hi there

I've seen few of them making at 2.0-2.1bar,but still I would have look on GT35 with 63AR housing which will spool similarly to GT30

Thanks,Jura

benboxall11

Thanks for your reply i want to be making around 580 to 620 hp how well would a gt35 do at this with low lag??

With the above statement in mind, what do you guys think of a Garret GTX3576 Stock Mount?

There is one for sale and the guy is saying it's good for 600hp, what do you think??

It is around about's the 600bhp region turbo,but you will definitely need proper supporting engine mods to achieve it.SJ.

If you are going with twisted or rotated setup then I would go with billet GTX,they spool faster and make bit more power

This "X" means Billet and most of people over here using Scoobyclinic GTX series or Lateral GTX which are most proven on the cars,those turbo are based on GTX series,but they using their own billet wheels and own exhaust housing

Old GT(non billet) spools slower and make less power,but I've seen few GT3582 make nice power at reasonable boost,all depends on more factors

Hope this helps

Thanks,Jura

I still wouldn't go with stock mount GT35 on the car,max turbo which I would use as stock mount position turbo is MDX321V or SC50/54 this depends on engine,with right twisted turbo setup you will have nice setup,that's my view

Hope this helps

Thanks,Jura

Anyone tell me best twin scroll turbo for 450-480 BHP? I understand it going to need supporting injectors and cooling etc etc but just want some suggestions for the turbo please guys. Oh it's a 2.0 litre JDM spec c engine bye the way.

As above there Lichtfield LM450 or MDX555,SC42+ and MDX321T Twin Scroll,those turbo should make this power(450bhp)

Hope this helps

Thanks,Jura

Thanks for the help guys.

Thanks for your reply Jura, really appreciate your input.
Unfortunately, this falls into a case of 'what's available'!!??
Yes, I could go buy one of those other turbo's but I'd be paying at least twice as much!

Is there a link/thread that explains 'twisted turbo setup' or would someone mind taking the time to maybe explain it for me please?
I think I know/understand it but that's only from reading about it while looking at other stuff, not specifically that subject

Many thanks

By going rotated it allows you to fit larger turbos then you could get to fit in the O.E position,plus the turbo spools up quicker and comes in more hard,but saying that you can still achieve good figures now with standard position turbos as many of my friends have with SC billet turbo's and achieve very good bhp figures.But it all depends how far that you want to go with your car as going rotated does add additional cost pipework,external wastegate etc....SJ.

Dazzles Fiesti

iTrader: (2)

Thanks SJ, that's what I thought it meant and why, so, taking it a little further, it's down to the up pipe that adjusts where the turbo sits?
I guess what I'm asking is, it isn't the turbo that's physically twisted but where/how the turbo mounts to the up pipe and therefore how the downpipe is routed??

Is that right?

Dazzles Fiesti

iTrader: (2)

Anyone answer my question??

You are answering your own questions.

Rotated setup fitted, turbo sits at an angle due to the up pipe and the down pipe is routed according to meet the centre section

Hi Dazzle

I would search and wait,they usually pop up sometimes for sale there,we are waited quiet while for Twisted turbo setup,but at the we are went with custom one

You can buy twisted turbo setup from Hayward and Scott like for 5speed or 6 speed for around £550-£600,you will need external wastegate,this will depends on turbo,but 44mm are most used and then turbo of yours choice,usually used non billet GT30/35 cost around £600-£750

Here is it how it looks,this has been from our old wagon







And how it looks



Hope this helps there


Thanks,Jura

Thank you for that

That does look cool Thanks for showing it

It sure did, thanks again Jura

Another fine rotated setup with a Holset

Thanks Boosted.
Is this just a picture you've found on the web or do you know the install?
I ask becuse I was wondering where the compressor outlet is routed?
From the picture, it looks like it might be routed underneath the MAF?
If so, I'm assuming that's because the Holset has a different outlet configuration to a normal Subaru Turbo?
