you should be able to find bits for the bottom end everywhere, any 18r parts should fit, though i'm not an expert on them. they were the most powerful of all r series engines. the 18r came out in celicas, coronas, trucks and god knows what else.

VERY reliable, parts can be a bitch, like the EFI thermostat housing, but most parts are the same as 18RC {toyota logic  }
Can be made to produce upto 230hp N/A and over 450hp boosted
i regularly rev mine to 7500-8000rpm, and its a stock 18RGU with std 40mm solex's 
my mileage is better than my old 85 model EFI commodore, and i flog the guts out of the corona all day long

to make 240 hp you would have to rev it 2 10000 rpm have 13.5 to 1 comp and have 475thou lift plus efi with 50mm throttles elf race fuel and the cams would be 330 duration and about 280 at 50 thou idle about 2500 rpm but your mate 1 most likely idles at 1000 and he drives it around the street

More than 100hp/litre from an old-school 8-valve engine is a BIG ask. Yes it can (and has) been done but as indicated above it would be a big-dollar full-house race engine which would be completely useless on the street. That sort of power is easy to get with forced induction, but NA? Forget it.
To answer the original questions:
- Parts availability is variable. Most of the bottom-end parts are interchangeable with 18R-C parts and thus easy to find, but other bits like timing gear which is specific to the DOHC models can be tricky to find. It can take a while to source EFI parts as not many people bothered with fuel-injected 18R-G's; most people took the easy route and used the twin-carb versions.
- Reliability is excellent. As with most R series engines the 18R-GEU is practically indestructible. The long timing chains can be a weak point but provided you replace them at the specified intervals you won't have any problems. The fuel injection system is very simple and when properly maintained will give no trouble.
- Fuel economy is very good if the engine is properly tuned, although there are a lot of poorly-tuned examples out there that get shocking fuel economy. The EFI system has a closed-loop function using an EGO sensor, so highway fuel economy is excellent. Even with the EGO sensor disconnected my 18R-GEU acheived 9L/100km.

Hi,
The earlier 18RG (Build 210, I think) had the highest compression ratio and idles at 1250rpm. They can ping a bit if you don't keep them tuned, especially with the current grades of petrol around.
You can always try and get the 503E engine, which was Toyotas ulitmate 18RG engine - though it was heavily modified in both the block and head and was for race purposes only. They could put out 600hp for endurance racing. Mind you, she'd be a bitch on the street 
Can you fit the 18RGEU head onto an 18RG? I ask this 'cos the 18RGEU had larger valves, and I was wondering if this would make any difference to performance, or maybe unperformance?

Yes, all 18R-G heads are interchangeable.

nevs motor may well put out 240hp when it is finished he as mentioned a figure to me well in the 5 figure bracket. He is getting it built by the people that did the group C celicas at bathurst.

the group c motors made 195 hp tops and that was with mechanical injection ,i should know wilko builds beech thomas grp c chickadee chicken celica and i own willo old car and that was about the same only the 503e motor made 230 240 hp and that was 16 valve 18rg special which was only availible to the factory race cars

Is it just me or are people getting the 503e mixed up with the 152e
I was under the inpression the the 16 valve 18r series engines were 152e, and the 503 has crank saddles more closely resembling the 3t and is a much more modern engine than the 152.
As far as the original post goes, yes, 18rgeu's are good engines with a fair amount of potential. Compression was higher in the 88210/230 series 18rg's (9.7:1) and also in the 88252 series engine. The early engines ran at an idle speed of 1000RPM +/- 50 rpm.
Only main problem over the EFi versions of the 18rg motors is that any change in cam profile can screw the performance unless the EFI system is changed to run on alternative or after market computer and MAP sensor. Uni chips could also be used to remedy problems arising from cam profile changes.

Hi,
The following text is from the toysports (TRD) site:-
++++++++++++++++++++
The ultimate versions of both the 2TG and 18RG were made by TRD- they were known as the 151E and 152E respectively and came with 16 valve heads, both were available in carburetor (50mm Mikunis) and fuel injection (mechanical Denso) models. There was also a 150E 16-valve version of the 3K / 4K engines. These 16 valve heads were the forerunners of today's 4AG, 3SG, 7MG, and 2JZG engines. These were race only non-production heads, with heavily modified blocks. The 152E race engine was used for US Toyota's early back-to-back victories in desert/stadium racing and IMSA GTU events. The 152E was used in Europe for the FIA World Rally Cup series.
The most famous and successful Toyota Race engine- the 503E was used in Toyota's Triumphant Championship seasons in IMSA GTO / GTP, Pikes Peak, Le Mans, and in the mid-90s Japan Touring Cup Championship. It is important to note that the 16 valve cylinder head layout from the 152E engine and the T block crankshaft saddle design were used as design base for this ultimate Toyota 4 cylinder Turbocharged race engine. The 503E represented the most powerful 4 cylinders in competition history developing over 1000HP in qualifying tune, 800HP for sprint races, and 600 for endurance events. IMPRESSIVE.
++++++++++++++++++++++
So, I guess you're right about the 152E being the ultimate of the "recognisable" 18RG series. But, then again, the 503E was the next advance on top of that, borrowing from the previous (152E and T block crankshaft) engines. I dunno where you'd draw the line, but I do know that if I had a 503E engine in my car I would prolly spoil my pants each time I plant my foot.

Thanks people100 etc in awnser to celica 45 it is obtainable my engine is runnin 12.0:1 comp runs on avgas induction is via two 48 dellortos with 44mm chokes the cams have approx.440 thou lift etc. the guy who built this engine used to build the heads and worked on the crew for wally scott who used to run an 18rg powered ra 40 it was producin 238hp at 10000rpm on 45mm webers. yes my engine is also 2.2l and owes me more money than i care to remember but who can deny that a strong toyota twin cam pullin 8500+rpm on twin 48s doesnt sound horny.if you like in the near future i will try to get some in car footage and post it for people to see and hear

not to be rude but if wally scotts made 238 hp shit then willos and chickadee chickens car must have made 300 hp cause wally always got lapped at bathurst by bailey and co and they were always in front and baileys car towards the end of group c was more reliable than willos who had a formala 2 bottom end will look up the bathurst stats tonight sometime ,also not being rude he is pulling your pud at bathurst to 10000 ha ha h a like it would last maybe 1 lap group c also had a comp of 10.5 to 1 tops you wernt aloud to port the head only clean up the dags also the cars had 48mm webbers even the corolla levin had the same size they went to injection to stop the carbies fouling up all the time

Hi,
I used to love watching Willos little Celica go around Bathurst. I think he was the first guy to have an in-car camera. On the main scoreboard you'd see the V8's in the first 7 positions and I think Willo was running 8th at one stage. Not bad for a little 4-banger.
I still watch Bathurst, but I miss the other cars and classes, and wish they'd bring them back.
I was most amused when Godzilla ate up the field and all the V8-heads were crying foul over it. Now we just got Fords, and Holdens, and Fords, and Holdens, and so on... bland and more bland.. ho-hum, yawn...

Not a bad place to finish, considering it's a little 4banger against all those larger capacity engines.

Hi,
I was under the impression the most powerful of the stock production 18RG engines was the early build, 9.7:1 compression ratio 18RG. The subsequent engines (18RGEU etc) were of lower power because they had lower compression ratios. The large valves on the later heads were put in to counteract this lower power but still the original 18RG had the most power of 145bhp. The others were in the 130/120 bhp region.

Well if you actually read what i wrote it says that the motor in wallys car was producing 238hp not mine mine is still to be put on a dyno but as soon as it is i will be quite happy to post figures etc coz at the end of the day nothing beats seeing it in black and white.
