looking to go 2.1 on a cdb which turbo would you guys recommend i'm thinking sc54 to keep standard position but rotate the housing for shortened pipework? also what figures you making cars an 06 blob sti, cheers- Stu

Stock 35R with a .63 works well.

A Billet 35R with a .63 would be even better !

V Power fuel used there btw..

I'd be more leaning towards a GT30R billet on a 2.1 - should do the figure seen from the GT35R too.

As always it will depend what spec the build is, head studs etc etc etc as to whats safe for power / boost.

I have a GT3076R from Aet-turbos and a P0021 holding things up...

No LOL

id be interested to see what you go with im going to be looking for a new turbo in replace of my rcm450 but want a guaranteed 500bhp on standard position and pump fuel,what are you aiming for?

MartynJ

No such thing as a sure thing !

cant understand why people want to go for a gt30 when a bolt on md 321v will virtually give the same results but a lot cheaper? as will et bolt on sorry martyn i forgot the number,

snake1906

iTrader: (4)

the 321v billet must be around there

MartynJ

Not quite in my experience of the non Billet version, haven't had a Billet version to map yet but suspect from what Mark was saying on his thread that they will produce similar power but spool even better.
Don't get me wrong the V is a cracking turbo, but I have yet to see one crack 500bhp on straight pump fuel.
In my experience of many of the bolt on turbos out there inc the S206/S215B, SC36/40/42/46/50/54, FP Green HTA and the 321V, to be certain of cracking the 500bhp on pump fuel you'll require an excellent spec and a following wind

cheers m8 ive got a pretty good spec all i need is the turbo to go with it i only want 500bhp as dont want the engine apart again for headwork so 500 or just over is where ill stay untill i get bored then move on but i wont settle for less than 500 and dont want to go meths again so does that leave me with a rotated kit? twice the price for a guaranteed 500 when a direct bolt on may do it hmm,, sorry to the op for the hijack but im sure this is information that may help you also

MartynJ

A rotated kit is your best option to guarantee it even at double the cost, so get yourself a decent kit, fit it with a Billet GT30 .63 and you won't regret it.

Going from a MD321V to a rotated GT30.63

I couldnt believe the difference with how it comes on boost now, even with them both running nearly the same power

How many rpm's difference Anger?

Does it go from nothing to everything?

Anger

iTrader: (4)

It was more linear before, as the graph for the GT30 just goes straight up

2.1bar on the V to make 500bhp on pump fuel compared to 1.7 on the GT30.63 on the same fuel

Something addictive about the way a rotated turbo delivers the power compared to a standard postion turbo, very difficult to quantify in words though this smiley comes close

Shmerman

I will be putting a V on my freshly bult 2.1

I also am hoping for 500 on v power. The only thing I haven't done is work the heads. I will be sticking with the stock v3 STi heads for now.

I have rotated the turbo for a much straighter inlet track and much shorter pipework so hopefully will be nice and spooly

MartynJ

Could you post your graphs for them both Jay, don't remember seeing the one for your V.

basically this is what im looking for 500-600bhp from standard position and v- power if posible?

Tidgy

don't cahse a peak power figure, chase drivability, a well sorted 480bhp car will easily see off a poorly sorted 500bhp car

Sleiper STI

iTrader: (2)

i want a rapid road car mate but just want over 500 for the pub banter, i have my eye on the sc54 billet as i reckon this could be the way to go?

Tidgy

have a chat with the guys up at clinic then is by far the best option, personaly i wouldn't get hung up on a figure's, no point in having 500bhp if the power band is totaly wrong for the use of the car.

dazdavies

iTrader: (22)

You'll be lucky to get over 500bhp on any standard mount turbo on V Power never mind 600.

Sleiper STI

iTrader: (2)

fair do's mate i realise 600 is a bit optimistic but sureley the sc54 on a 2.1 would see 500-530 if set up properly etc?

wrighty338

iTrader: (33)

rest of the spec, any headwork?

stevebt

iTrader: (8)

I would go with a billet md321v, rotated turbo systems will cost a lot more money and with bigger power comes bigger problems and less reliability.

snake1906

iTrader: (4)

when are you planning on making this happen m8? as you,v said and i agree as i wouldnt be happy with 1 bhp less than 500 and if i cant get a standard position turbo that will make it then i wont bother

Anger

iTrader: (4)

Theres one with slightly more power knocking about, maybe in the car but the covers over it and its all tied

No point of posting the rotated graph as its on a 2.35
