twin scroll turbo
 

can these work well on a 99/00 year engine and what sort of power/boost levels can be achieved using one of these turbo's

You'll need the up and down pipes to go with it of course. See Simon Lines thread in projects for details of just this.

ive just read simon's thread. and he reckons he couldnt get more than 12.8 secs 1/4 mile at 2bar :eek: doesnt sound like a turbo i would like

I think if you really want a drag strip power monster then you either need Mr Wallis to build a cheap mota for you for old cereal packets ;) Or be prepared for big £££'s to get to the 11's and 10's. Just a change of turbo isn't going to get you the results you want IMO but I guess you know that already :(

What power are you after and where will you use it?

F

might have to take myturbo off for a service, but if its coming off im thinking off adding a new turbo ?????not too bothered on power just want acceleration :D

I asked this before :D

as i recall bob rawle is running about 370bhp on an sti8 or 9 with one of these. I think it would be a good project, maybe with ported headers and a trimmed turbine you could see near on 400...

I think this would make a very nicely driveable car, I get a bit fed up of the lag on the 05/06 sometimes. Having said that you could probably do a 2.5l conversion for not too much extra.

Dave

so have you still got your 05/06 on then :) there may be a little lag on mine but when it comes on boost :D i get full 1.5 bar of boost at 3300rpm so its not too bad on mine

Well I think the TD04 takes an age to spool up so anything later is a pain :(

F

Yup, still got it. Not driven the car since october though :eek: :(

If you're happy with the 05/06 why not try an 06 turbine in the 05 housing, as far as I recall it has been done, a bit of machining is required and it's good for a bit of extra grunt.

BTW have you got a serious grudge against your engine internals? :D I don't think many people have pushed a standard engine so far!

Good luck,

Dave

I just found in USA a Legacy twin scroll TD04 complete with all the required parts for WRX fitment!
What is this, is the first time I read about this turbo do you know if it fits in our cars?

just found out its a new up and down pipe, so ive just bought a VF35 instead for when mine is off

Join the club Steve :D The VF35 is the new 'black' ;) And didn't I say about the up and DP's on post 2? :rolleyes: ;)

F

th VF35 is only temp for me say about a month or so then the td05/06 goes back on ;)

VF35 :confused: Strange choice. Can you post a comparison of the two when it's on?

i will have no way to do tech comparisons but i can give my opinion if that helps :)

Well I know the specs of them both, but an opinion is always better imho. Numbers can't tell you 'feel'

Dave

Why's the VF35 a strange choice???? :)

it was cheap enough :) and can still flow to about 340/350ish so will be ok for me while mine is being seviced :)

Ok for me too i hope as i have one sat on my bedroom floor :D

The VF35's a small turbo compared to the one he's using now. As far as I know the best realistic power made from this turbo is about 330bhp, 360 has been claimed but doubtful....... (flamesuit on :D ).
