question about turbo size
would a TO4B with a .60 compressor and 1.15 divided exhaust housing be suitable for a 2110 running EFI?

The rear size is too big, you'd want to get closer to a 0.8 or less. What redline are you planning on?
Cheers

yep thats what i thought with the exhaust housing
the turbo's been set up for a extendport 13b and now we're not using it so i was thinking of throwing it on the bug
does anyone know where i could get a .81 or .84 housing that would suit here in oz
the turbo's a garrett
thanks

Awwwwhawhawhaw, that turbo would take a lifetime to spool coming from a breathy 13b.
The kind of turbo you are looking at would be good for prolly 400 + Hp. With a rear housing like that you would expect very slow spooling and then a
sledgehammer hit at prolly 5000rpm!!!
What might be a good alternative is to source one offen something like an RB20/25 single turbo Nissan Skyline.
These things use a T3 flange and are an excellent replacement on a strong 2 litre engine.. Good for 200RW KW @ 7000rpm plus.
Being mostly ceramic zorst wheels, they are fairly intolerant of overspeeding and surging and so regularly discarded by the boost up 6 cyl RB Nissan
boys and they go usually very cheaply.
Yahoo Auto groups and the like are where to find them.

the original turbo for the 13b was a holset HX40 rated around 700 hp
that would of hit like a sledgehammer 
both turbo's were set up for 1/4 mile so low down wouldn't have mattered to much
wanna use it on a 2110 now so trying to find a good setup that will work
not to worried about daily driving ability as it won't be a d/driver

Personally your best bet would be to go for a high flowed T3 or TO4 front with a T3 rear as you won't have enough exhaust gas flow and heat to get
the TO4 rear to really work untill your about 7000rpm!
Rotaries have a far superior gas flow (compared to piston engines) that allows them to run big rears
Following on from tassupervee other tubo sources are VL turbos, FJ20's (if you can still find a FJ20) would be ideal for your capacity
Plus you won't have to worry about a wastegate as these are internally gated
Cheers

Hehehehe yer Flintstones, I never bothered mentioning the T3's off the FJ's and RB30's. Theyre pretty old school now and there are jag of better
and cheaper choices these days!
Ill have one spare off my FJ20et shortly. Ive got a pristine T25G to go on it. Stock boost see so altho not a good performance option should work well
enough.

What type of 2L have you got?
What REAL power will it make?
And most importantly what do your heads flow?
there is no point putting a turbo on that will out flow the heads and engine.
it will just spool slowly and never make good power.

Would a RHF5 turbo be any good on 2L dub running p/p 043s and how do you get around the issue of most turbos being oil & watercooled?
Thanks |

if u want a cheap oil cooled only turbo look out for a 12A RX7 turbo, they work very well on a 2L type1 setup
