It cost me around $500 in parts for my RG including full RG gasket set, rings, bearings, timing chains, clutch, water pump, valves, tensioner, etc...
Don't know how much for rebuild as my old man is a mechanic so I've never really needed to deal with that.
As far as making it quicker there are a number of different roads to take, its all limited by how much you are willing to spend. A quick fix would be an engine conversion to a 1G or similar, but the RG is a nice cult engine to have!

major clod, Can u tell me were u got all this stuff for $500?
Oh yer, the parts for a 18r are pretty available, but the timing chain and and stuff is said to be a bit harder to find, or very pricey.
Performance wise, id say a nice carby, perhaps a webber but i personally think they are overtuned, u drive to the other side of town and they are outa tune sorta thing. i think i will try and make a new holley or somthing work for mine. Valve job and extractors would probly help out to.

Well, It depends how much you replace.
We did everything from pistons (genuine parts), through auxilliary (sp?) shaft bearings, timing dampers (not slipper) to welsch plugs and paint.
This cost around the $2175.93 mark. I know we could have got some bits cheaper, but then that doesn't include the cost of a replacement head (10" crack) or shotpening con rods.
Basically, you can get a gasket kit from ACL
I've got a top end rebuild kit here with part number DK690.
Something like that will get you somewhere. Chrome rings were arount the $60 mark for Hasting Premium.
If you don't do pistons and big bits & dampers, you can get away with it for not too much, like the other guys did.
It all adds up though.

ok
i can give u vague prices
rings $60 for CRM or $40 for normal
bearings $80 for BE and mains {use king bearings, far superior to ACL}
chains, not really sure but heres the non gen part numbers
Endurotec brand, DR982 which is the top chain, i paid $24 but retail would be like $35 or so
Generic brand, DR622, which is bottom chain, i paid $16 so retail is prolly like 30-35
Gaskets part number of both durapro and ACL VRS is DK690, i'd go for the ACL one tho, it has a very good exhaust gasket that has fire rings around all the ports, and
its like 40% cheaper
Valve springs Not exactly sure what brand but the part number is RR4 for a set of dual valve springs {they suit the 250 head too} prolly like $160 or so
when i get PN's for the small ends and aux bearings i'll post them too

I can tell you that those valve springs (RR4) are made by Performance Springs. My brother has those in his engine.
We have 3mm aluminium spacers under them to make up some of the installed height. We were informed that we would have to space them to get the right height for those springs.
Verdict: Pretty good, 8000RMP and no hint of valve bounce.
$88 for valve stem seals, WOW BABY.
We paid $12 for the whole set.
Aahh the joys of a machinist that knows that Toyota "2L" Diesol engines are about the only other engine (2t/3TG excluded) that use an 8.5mm valve stem.
We paid a little extra for the top chain, so that we could get one that didn't have split rollers (they tend to come off and things go to shit).
The other thing is to make sure that your main bearings are right. There are two types apparently, sperarate thrust and integral thrust for 18R blocks.
We chose to go for the chrome rings because cast ones were not advisable for high revving engines.

Yea, sure, you can get them going pretty hard.
I am trying to decide whether to go for 300hp with a turbo (engineering $$$$$) or go for 200hp with no turbo.
I've already got many of the turbo bits (and I found another engine at a swap meet today, with a turbo drain hole in the sump and 8.5:1 pistons !!!! I know, I didn't know these existed, but they do, it;s cast into their crown! 88232 gen number.
Naturally aspirated is always an option.
When you say big carbies, just how big are we talking?
you can rebuild these incompletely, just do the bearings, rings and anything that is either stuffed or seals oil, and the timing chains.
I expect you would do that for a relatively reasonable price.

you can rebuild it cheaply for around the $300 mark....bigger carbs and extracters will pretty much get you know where in the big picture...why supply more fuel if your engine cant use it..it only floods it and marks it die quicker....id turbo it if your keen on keeping that engine...so far i think my build is up to about $1000 and ive almost got all the stuff i need now....
