thanks zen,what difference does this 16g compressor cover make?I take it that they have been made with bigger compressor cover/housings too.
What size exhaust housings do they come with?standard td05 7cm, as i have seen greddy do one with a 8cm and there is a 10cm housing for the 200sx.

Rollers,
People are happy to help you, but whilst you have been asked several times, you still haven't said what you're actually wanting to achieve, so it's very hard for anyone to suggest what might suit you best.
Just what are you trying to achieve ?

380+bhp ,good spool.I know the answer td05 18g.
I was wondering what it was made up of,after major research i found it was basically a greddy/trust t518z,which consists of td05h exhaust housing 8cm, td05h turbine wheel,18g compressor wheel and a small td06 compressor cover.
If this is what the uk guys supply thats great.
Shame it's oil cooled only,can it be converted to water cooled aswell?
If thats what the uk guys supply even better.
Also could you fit a 10cm housing or titanium shaft like the evo td05's.
Do you think that might improve things?

>>> No, the evo turbo rotates the other way. You can try but you will get 0.1 bar max boost
I know someone who actually tried this !

Andy,
At least it was posative boost, I'd have thought he'd have been in permanent vacuum
Rollers,
The Trust/Greddy turbo isn't a direct fit, and the kit will come with a custom up & down pipe, and external waste gate.
The TD05H-18G you'll get offered by the guys mentioned on here, is a "direct bolt on", and will also be water cooled. It will also be way cheaper than the Trust/Greddy kit.
With the correct supporting mod's, it is capable of 380bhp.

td05 18g makes for a great road car turbo on a 2.0L impreza imho.
very punchy and can hold some quite meaty boost as far as you dare push!
I have one of the deadbolt 18g's, td05 hotside with 18g compressor wheel and housing, bolt on and water cooled, it even spins the right way
its fast becoming the turbo of choice as it represents superb value for money.
I am sure there was talk of an (or some) 18g('s) making 400 brake with the right mods and possibly some enhanced fuel.
my own is now pushing 1.60bar through the midrange, but I lost my bottle and had the top end tailed down to 1.45bar.

yep 18g is definetly the way to go,from the details of the greddy kit i've found it it uses the stock manifold,doesn't come with a actuator and comes with a flange to bolt up to the stock downpipe,where did you get your information?
greddy offer a t518z(td05 18g) bolt on upgrade for the 200sx also which has the option of a 10cm housing (this spins the right way). Also i thought the titanium shaft was a option you could specify and add later(can't see how direction matters to a shaft.).I'm not a turbo maker so could be talking crap.
Anyway from the research i've been doing the t518g outperforms (spool characteristics) any turbo that produces 400bhp(18g compressor max output).

lol, or even Scottish hp.....apparently
The turbine wheel and shaft are the one item therefore are rotation specific, as are some of the bearings.
Generally a larger exhaust housing (not available as a bolt on) will increase lag with a possible minor increase in top end flow.
All else equal, a water cooled core will last longer than an oil only core, hot shutdowns are not an issue. Thats what the deadbolt 2 year guarantee is based on.

japanese horses(ps) t518z 373bhp(1.4bar) 8cm housing.
I take it most of these hybrids use the standard 7cm exhasut housings that came on the uk model tdo5 16g.
greddy/mhi created the 8cm housing which you can get hold of.
The fp18g used to come with the greddy compressor cover!

Why do you think you need a 8cm hot side ?
I have seen 440bhp from an 05 turbine in an original housing and they are capable of more with an 06 turbine.
If you get the right turbo in the first place, you will not need to convert it. (I imagine that would screw your warranty)

Rollers,
So far in this thread, you have received advice and guidence from three of the most respected tuners of scoobs in the country.
It would be 'criminal' not to listen to their advice
Buy a TD05 18g......... you won't regret it...... Yes, I have got one !!!!!

i WILL buy a td05 18g there is absolutely no doubt,but i want the best spec possible. I'm thinking that greddy did some r&d and wouldn't produce a one-off 8cm housing if they didn't feel it necessary,my thoughts(i'm not a tuner) is that the bigger exhaust housing will mean i gain 10bhp more top-end with the expensive of a few hundread rpm spool-up which i can live with.If the experts know differently then please let me know after all i/we are all here to learn.

My experience is that you only need to go larger on exhaust housing if it is causing a restriction. No restriction - no gain. The potential exists however to introduce more lag.
As I said earlier, the std exhaust housing is not the limiting factor, this is backed up by various versions of this turbo in this exhaust housing having produced higher numbers than an 18G compressor will flow.
A bit like the IHI P18 and P20 exhaust housings, the midsize P18 is good for well over 400bhp with the correct core, substituting a larger P20 will increase lag. P20 will however be the housing of choice for 450+bhp conversions.
You do seem to have made your mind up to go for the more expensive non water cooled greddy unit which you tell us has made slightly less bhp that most of the UK 18G conversions
Let us know how you get on, it will be interesting to compare back to back dyno or 1/4 mile results with our UK version.

Thanks for your comments,i believe the limiting factors of the 18g is probably the exhaust wheel just like the pe1820 which has a tiny 53/48 in/ex compared with the superior 56/49 of the td05h.The 8cm should free up a little backpressure at the top-end but i could be wrong.
Would the small td06 compressor cover be of any benefit to a reworked td05 cover.
Do you think any clipping is invloved with these turbos?
