Turbo for an 18RGU???

Just after a bit of advice on turbo type to get for a 18RGU EFI.
I'm after 300HP at the wheels. And yes there is going to be a lot of work done to the motor to get that.
I know ball-bearing turbos are good but what type would be best.
I was think'n T-25, T-28 or T03/04 hybrid?
Any others???
Or what the hey, a T-88 or a Y2K will do!
LOL
Going to high-flow the turbo and put on a bar and plate intercooler to keep temps low.

I think the 'E' is the head design. It is possible to put carbies onto an EFI head if you really wanted. The 18r-geu heads had different valves and some other difference to the previous ones. I'm just going of the top of my head here but i'm sure someone will will correct me if i'm wrong.

Yeah, E is the head design, it's got the small cutouts for the injectors as opposed to the standard carby head. Also there's a cover doobie thing on one of the shorter sides of the head which is oval as opposed to "rounded rectangular" I found my first true 18R-GEU head by accident after buying a whole series 1 RA40 for $500... the guy didn't know what he was selling. but he got it for $200 so i guess he was happy. Anyways, i got me a genuine efi head so I'm happy. You can get the standard head modified by having someone machine cut the injector cutouts(I have 2 of those) but I wanted a genuine one so I'm happy... Although i do have 3 efi capable heads now...
Looking to buy all the efi gear minus head or a complete 18RG of any sort as long as the head isn't cracked so if anyne has one let me know.
Standard efi gear is what i'm particularly after(computer and wiring), for compliance purposes... engineers don't like aftermarket injection.

from the info i have gathered the G is for the twincam the E is for the efi system. and the U is for the valve design. and the heads dont have to be machined to get the injector cutouts. all you need to do it put some ink or something on the intake manifold. put it up against the head to leave an outline and scribe the outline. wipe your marking fluid off and attack it with a wood chisel. the alloy comes away very eaisily. you may thinkit is brutal, but afte ri removed most of what i wanted to i just hit it with my dremel and smoothed it all out. a round file would work too.

G = twin cam
E = EFI (not the type of head)
U = jap emissions controls
C = calafornian emissions controls
E does mean EFI.
If you put carbs on an original EFI engine, you should drop the E, and possibly the U.
Yeh, the 18R-GEU had bigger valves, but it was done in an attempt to restore the power that was lost from the new emission standards the engine had to comply with.

E does mean efi but it also means different head... trust me i have both... may post pictures when i eventually get my efi head back from the engine shop. But i told them not to hurry so it won't be for at least a few months.

although you are right about the E in 18-RGEU, there are 18-RGEU models with the sideraft carbies out there. This is because of the larger valves with the efi model and also because the efi system can be restricted on hp.
I have an 18-RGEU model with twin 40mm webers instead of the efi system. the engine is a normally aspirated 2L (non-turbo) with 60/25 cams, lightened flywheel, 2 1/4" extractors, high comp. pistons etc.
heres a pic of what i'm talking about
i've installed this into an st141 corona '84, pulls about 8 secs in 0-100kmh.
if i had somewhere to load my other pictures i could show you the car before and after the conversion.
if anyone is interested, just reply here.
regards,
jarrod

ok heres a picture of the engine bay with the stock 2S-C engine
now heres the engine bay with the recent 18-RGEU engine, with some mods including the power steering rack support - celica engines didn't come with power steering - electronic fuel pump, aircon brackets (aircon to be installed soon, its still winter). 
and heres the picture of the car: new paint job, mags, wider tyres, loud stereo system etc.
i have a heap of more photos to post but will post em when i make a website on the car, with all the mods and how to's.
so stay tuned...
regards,
jarrod

I used a T03 with T04 comp fan in it.
Plus I put 308 holden valves in the head, on avgas it pumped out 400hp very easily.
I then put a bigger cam 60/25 changed the EFI to quad throttle body with 8 injectors and custom inter cooler, custom made counter weighted crank (copy of TRD one), bore it out to run 90.5mm vw pistions,
Got a peck HP at 500 @ 5500 rpm. Spin 3 gears and run low 13's in full weight RA40.
Was a great car to drive, currently trying to rebuild it, sold the block off, and part of the EFI, am looking to fit a blower to the motor when I rebuild it this time.

Where did you get the VW pistons and are they the forged ones? I have 1 set(forged) but looking for a second one. Also would you still have the original computer and loom? no one i know seems to have one and I would like one very much. would make rego much easier...
Where did you get the crank? how much was it? Actually i'd be interested in a fully detailed description of exactly what you did, where you got parts and what it all cost.
Also, any idea of how to do a power steering conversion by spending as little $$ as possible on an RA40???

I got all your messages, Will sit down when i get some time and write out all the details,
The pistons are forged, and come from a 90.5mm type A bore kit, cost 450 last time I brought them, I think they are about 800 now. Got them from Pobjoy racing, he also made the copy crank for me.
