Hmm see I stil want the 330-40 mark but the spool of the td04 lol

Tidgy

by the very nature of the way turbo's work you wont see that. just drop down an extra gear and problem solved.

What can be expected from a sc32?

A 16G compared a td04 will feel laggy thats a given but it all depends what you want in a car, a SC32 will get you to the figures you want and wont be far off the td04 in spool but is it value for money against the gain....

Ok can you tel me what would be better, 2.0 with td04 hyrbid/sc32. 2.5 with td05 16g or td04 hyrbid or sc32?

Tidgy

I'd go for a sc36 on it myself, I think your worrying about lag too much, just learn to drive it using a bit higher revs.

There is a new revised SC36 Billet about to be released with ball bearing core instead of sleeve bearing,this should be a very quick spooling little blower and could be worth a look mate.

The sc32 is just a td04 hybrid really fella.

What can I expect with the sc36 on a 2.0? Also how much is it?

veerinder9

Well just looked at it on the sc website, sounds good, would be good if anyone had any results/graphs of what they got with that turbo on a 2.0

There are PLENTY of graphs on the SC turbo thread, you just need to find them!

IMO though, the jist is that the SC36 is the current best bet for a 2.0 turbo that gives great spool and power to the limit of a 5speed box ..... its a really good little blower!

if you were to run it on a 2.5 (not sure if its been done yet) youd end up with it spooling from idle i should imagine, but it might overspool at higher revs and limit top end power (which your doing anyway with your requirements).

I used to run a VF30 on my 2.5 and it was great for day to day drivability!

The sc36 has had very good results :| I think thats what I need, what supporting mods should I have to gt much as possible


My current spec:

Uk turbo rebuilt over 1k ago with cosworth headgaskets, acl race bearings
std pistons rods/open deck
Sti6 tmic
William motorsport unequal length headers with harvey smith up-pipe
3" decat all the way
440 injectors(i knw il have to chnge these to 550 atleast) hrc 310 fuel pump

Am I missing something?

Which car are you running classic or newage

iTrader: (20)

everyone will tell you its crap in standard form apart from chopperman who has one that he has had rebuilt because guess what?? it failed.

standard 2.5 is sh1te, rebuilt version with forged pistons etc will be a great engine.

the 2.0 has none of the 2.5s problems out the box.

Im running a classic mate

Im thinking of sticking with the 2.0 but slapping on the sc36 with JGM magic

VF 34 from andyF will spool well and give you the numbers for half the price.

iTrader: (68)

Bear in mind your gearbox will be on the limit with the power you're aiming for, so dont be suprised if it breaks

chopperman

Mines pretty standard apart from a forged pinned build, 100 cell sport cat with japspeed exhaust, 3 port, K&N panel filter and reacerom map.

Tidgy

i wouldn't say thats pretty standard lol forged and pinned is pretty largest thing you coudl do rather than closed deck blocking it lol

what is the current largest power running 2.5? as in still on the standard pistons and rods.

chopperman

true. I meant pretty standard as in performance mods Aviva didn't consider the forged build as modifications. They made a note of it but the underwriter said he classes it as a repair.

Tidgy

bonus lol

veerinder9

iTrader: (1)

Is that so? Is that brand new?

Tidgy

vf34 is a good turbo, bit rare though, aslo wont be as good as an sc36

vf34 on my old classic, 2.0, autronics mangement, front mount and few other mods

veerinder9

iTrader: (1)

Lol I know that im not to worried about that to be honest, would standard internals be able to cope with around the 360 mark? Its usually the boost that causes problems right?

veerinder9

iTrader: (1)

Good result, wouldnt mind paying abit more for a brand new turbo tbh, evrything on my car is new aprt frm tmic and the td05 turbo, that way I will know the history of vehicle aswel plus il be keeping car for ages anyway,

Tidgy

sc36 without a doubt then

veerinder9

iTrader: (1)

I guess thats sorted, time to save up for turbo, front mount, injectors

Im using tubular headers, is this a drawback? As ive been told I shouldnt use them below 400, but im using harveys smith trick uppipe which I thought was meant to help with spool?

jazzyjembreaze

iTrader: (11)

^
400 or below
Ported oem headers 2 bolt Harvey tric up - pipe
Is whats required on a 2.5 sti running a standard VF 43
I achieved 387 bhp & 420 ftlbs on ecutek
Mapped by Bob Rawle

Above 400
You want tubular headers & 3 bolt Harvey tric up -pipe
Turbo choice is yours to choose
Sc46 or MD321V billet is my choice

veerinder9

iTrader: (1)

Ahhh I really dont want to change my headers and uppipe now lol, is it a bad thing though having them below 400, like do they cause loss of power? Is there any facts to why the wont be good below 400 as they would be above 400?
