Is 100RWKW possible from an 18RG???
I wanted to rip the donk out at the end of the year, But was unsure what eay to go.......
I found a placxe that grinds cams for $100 each so was considering getting some spare cams and getting them ground.....And with some port/polishing.....Along with 60thou overbore........Thats where i run out of ideas....
Am i kidding myself?
OR should i go the 1GGTE 
Cheers
Ben

Just go the 1GGTE and don't waste your time/money, unless you really have to.... Instant Hp with the advantage of getting more later on down the track.

100kW from an 18R-G? I don't think that engine would be very nice to drive around town!
Just go the 1G-GTE. Mine made 124.8kW at the dyno day which matched a 1UZ-FE... Those things are rated at 194kW...
My engine is stock too.... Air filter and 2.5" exhaust... Drinks between 11L/100km and 13L/100km... Can't complain about that!
Darren's 1G-GTE running 14psi and a 3" exhaust made over 150kW.

100kw at the flywheel wouldn't be hard (that's about 160hp, which is only 15 more than the original 18R-G), but 100kw at the wheels would be a bit more involved... pretty much a race-spec engine if you wanted to keep it NA. Of course you could piss it in with a turbo.

100kw at the wheels could also depend on how much your dyno operator wants to either please u or get money out of u...

What you reckon you would get out of supercharged 18RG

How much do you want to spend? There's really no limit to how far you can go, it just depends how deep your pockets are!

I've looked into modding the 18R-G a fair bit, and in most cases, the 1G is cheaper to do (with me doing all or most of the work myself). Building an SC or turbo 18R-G, you're looking at an aftermarket ECU, bigger injectors, possibly an intercooler, plus any extra costs like cams or other engine internals. It adds up, especially if you want to do it right.

I was under the impression that the 1ggte was non turbo?
I dont want to go a turb'd engine yet.....Im still 16....17 in a week.....
Budget: Depends if i keep the car, if i do.......Hmmmmm Depends on the $$ difference between getting a 1GGTE installed.....As opposed to a 18RG rebuild?
If i get a 1ggte do i need 1GGTE box, Manifolds etc? how much am i looking at and whats compatible from my 18RG?

The 'T' in 1GGTE stands for turbocharged. The non-turbo version is 1GGE.

About the 1G...
1G-GTE (Twin Turbo 24 Valve Twin Cam 6 Cylinder)
1G is the engine model / family
G means wide angle cams
T means turbo!
E means EFI
There is a 1G-GE (24 Valve Twin Cam 6 Cylinder)
If you want to do a engine swap the best idear would be to get a "front cut" from an importer, make up some custom engine mounts and then swap over (will prbly be a bit of work tho!)
I think u can get 1G-GE front cuts for around $800 - $1000?

Go with the 1G-GE or a 1JZGTE I am only keeping the 18RG to try and Keep the car to GT spec's.

a stock standard 18R-GeU at the flywheel will put out 101 kw i think the 18R-G is very close to that. go the 1 G i rebuilt my 18R-GEU and it cost a hell of a lot of money. and i could have bought a 1 G for less than it cost me to rebuild it. but know i know what is inside my engine and how far i can push it. with the second hand motors there are always unknown things about them like how long since the oil was changed how many K;s it has done ect ect.

can you guys actually put a figure to "helluva lotta money"??
I've spent around $2000 on my 18R-GEU and when i bolt the turbo on I'm expecting at least 300hp. I don't really consider $2000 to be that much money since that's what you'll have to pay to do a "proper" rebuild of any engine.

Ive got an RA28 celica, with the 18RGU... just wondering what the difference is with this motor compared to the 18RG you guys are talking about?
Also would there be much performance increase on this motor if it has twin webers fitted? because mine has dual twin webbers and full extractor exhaust system.....
i dont know much about what this model celica (GT 2000) came with from factory, so any info would be great.
Cheers

Raistlin all up i spent about $1500 on parts for my 18R-GEU thats including some porting and a new(secondhand reground) crank and a new rod. i spose it isnt to much for a basicly brand new motor but im 18 at the moment and i didnt have that sorta money laying around. and i assembled it on my own so labour wasnt involved.
im still tinkering with all my cam timing and ignition timing and that sorta good fun. but at the moment i am only getting about 300 ks to a tank which is giving me the shits.
im thinking about getting all the base setting preety much right then getting it dyno tuned. its sort of has the power charicteristics of a two stroke dirt bike at the moment noting till 4500 rpm and it kicks in then the power tapers off at 6 grand and is as flat as anthing till about 6500 rpm where it wants to stop revving. so i think a little tuning is in order

As I said before, for $2000-$3000, I could do a 1G-GTE conversion on my RA23. What I was considering was supercharging my 18R-G. To do so, I'd need a fresh bottom end (current 18R-G has probs in that area), new cams to suit the SC (current cams will have too much overlap), then I'd need to buy a 1G supercharger, get a custom crank pulley made, bigger injectors, *good* ECU, intercooler, piping etc. On my calculations, I'd be looking at $3000 plus the cost of the fresh bottom end. Sure, it'd be a nice motor, something different, but it's not something that's cost effective at the moment.

100RWKW is about 200hp at the flywheel, and yes this is posiable from a 2litre 18RG or 2TG. It may be a bit easier if you bore it out to 2.2 litres or what ever the standard 18RG overbore is, not sure.
I say go the full race 18R-G, quad throttles, big air horns. Buetifull.
I'm not sure, but I think you want the bottom end ballanced so you can take it to 8000rpm with ease. Use a compression ratio of about 10.5:1. Have the head ported, use new valve springs. Use camshafts of about 304 degrees duration. 45mm carbies. The rest is tuning.

I'm looking at getting some of those VW pistons into the country if anyone's interested. I think they'd be around $600-$700... Not sure because of shipping. I did the bore to 90.5 in mine and used flat top pistons for low compression(will be turbo) and didn't need to machine the valve reliefs in the pistons. Also looking at making up some cheap effective efi computers(fuel and spark) designed for my 18R-GTEU but adaptable to other motors...

Just raise the compression (shaving the head) and run it on higher octane rating petrol (about 10.5 -> 10.8 can be run on Ultimate 98 or similar, although I recommend using valve conditioner additive because that engine is not so well matched to UNleaded petrol).
If you are obsessed with a horsepower figure and not on driveability, then you can always port and polish the head to have ridiculous amounts of top end power but as much torque down-low as a stock Charade. Same goes for grinding cams.
Of course, making sure the engine free-runs could be a good thing as well.
It just comes down to matching the right parts to the task, for a given budget, with good design and thought to all aspects.
200hp at the engine (ie 100 kW at the wheels) is possible.
If I were you though, I'd personally get a better engine to start off with.

About the 2Y pully, isnt it only a 3rib, while the sc14 has a 5 rib belt? can anyone confirm/deny this?

CHASSIS DYNOS ARE A TUNING AND DIRECT COMPARISON TOOL, NOT AN ACCURATE MEASURE OF POWER OUTPUT.
i know of people getting 90fwkw from certain "friendly" dynos with stock AE92 SX (4age)

Re: 100RWKW from 18RG?
"get a custom crank pulley made,"?? Save your self the money and use the pulley set from a 2Y hilux motor.
