18RG DOHC, but 8V only...

[-e f i n i-]

18RGEU...
Yeah at first it was a nice find to know that this engine develops 145hp with EFI. But I was at a disbelieve when i found out it is a DOHC with only 8 valves!

Though I can't find anything that proves this engine is NA, but looking at the code, its GE, not GTE, so it must be NA, my friend said so too.

So really, i wanna ask your professional oppinions, is this engine worth modding? At first, I got really interested in this engine quite long ago, but my friend said it had no potential, okay fine! Few months later, after reading articles about this engine and how glorious it was when it was built by TOSCO (i guess thats the name), i found out that one of the racing versions they built had 330hp NA at 2.2L, participating in the "under 2.5 class". One thing interesting I found out that old engines like this can be bored out to 2.2L alone, and if you wanna take the extra hassle to stroke it, the crank from 22R can be used to make it 2.4L.

Thinking about it, i start to wonder, if its 8V, air cant flow as much as a 16V in its class, but how did TOSCO make 330hp out of it NA?

So here comes the questions. Is this engine really worth modifying?
Turbocharge it, or leave it NA?
Individual throttlebodies or Weber or Mikuni or Solex?

500WHP also can...

2tg also can be bored till 2.2

2tg also can be bored till 2.2

for real??

U don't need to bore. Just find 3T's bottom end and u gain 1.8. It can be bored those. But from 1.6 to 2.2L is so hardcore. Even though it is metal and not aluminum or alloy. T series head can be used between 1T to 12T engines. But everyone seems to be using 2T and 3T blocks. Seems to be the toughest ones. Philipines esspecially like to make 400hp 2T/3T drag engines in turbo form.

18RG... from what i heard from some friends of mine, gives hell of problems for cars with newer engines. But parts are even harder to find compared to 2T/3T. If u wanna see a 18RG engine, Mun Lee still has one, and its engine only. Its big and nasty and has a big Yamaha engraved on its head. But its quite trashed. I thought wanna buy it cheap and rebuild and stuff it in my TE. But then i horror at the thought that i would be stuck at finding parts for it.

But come to think of it, 3T-GTE seems more nicer. hehehe.

Net, if we use the block from 3T on 2T, the block can still be bored out further right?
Last nite i watched Apprentice, trump said something bout knowing when to fold, or something like that, i cant remember...
thats the case now really. i've fallen in love with the idea of modding an 18RG, but a 3SGTE would surely be better, and easier and cheaper to mod too. I think parts for 18RG would have to be custom made... blame TOSCO for building the 2.2L 18RG with 330hp... now i love 18RG...

U see, 18RG has only 8 valves, but how did they make 330hp out of it? cuz the head flows well?

So guys, given 3SGTE and 18RG, which would you take, and why?

 

[EFN]

Yup, 3T-GTE would be the wise choice. Like Netmatrix said, 3T and 2T are rigorously proven to be THE motor used by most Americans, Jamaicans, Phillies for hardcore boosting monsters. Most of them clocking very respectable 11s, 10, 9s and even 8s Quartermile time. These buggers are damned tough ya.

YAMAHA Rules!

 

[20vturbo]

talking bout 8 second...remember paradise racing 3tc-turbo?

 

[-e f i n i-]

hmmm.... if wanna mod these engines, i guess almost all parts have to be customized...
but toysport does have some parts for 18RG... at the old site la...

when talk about parts do consider the chanses of you getting it. don't think something like "there is parts in this world", instead think "what parts can I get my hands on".

few years back i use to think something like "4ag go 220hp, i can get this and that cuz this company and that company got manufacture them", but now.. :( money problem lar... and dunno how to get also

 

[LevinTE27]

3TC da best.... engine so damn easy to get.. RM300+ can get a complete engine hahahhaaha...
piston use forged one, bore it. put in the longer stroke crank, 2TC head, kekekeke..
2.2++ liter engine.

now my gang under project one 3TC turbo push rod engine , will update the result maybe few month later.
another one 2TG hybrid 3T block turbo KE70 already complete, waiting for wolf 3D ecu.
old skool rock..

look at the block and stock rod, damn kaw strong man! any way dun use 3TG head, cos it dont flow as good as push rod 2T or 2TG head.

oh guys.. sorry my mistake...
the 330hp 18RG isnt 8V, but 16V. Head specially built by tosco! Unfair!!!!
rolla, at least we know its possible, right?

hmmm.. i thought pushrods cant rev high?

custom made head, same as the 16v head custom made for 4K racing engine.

old pushroad can't rev high, but new one isn't. so far i see they push as high as 8k or even more.. just very loud lolx...

 

[-e f i n i-]

ehhh rollakid, why so long never see u online on msn?
hey, how would it be if we order an 18RG from toysport eh?
hehehe

 

[Joeker]

Me dunno shitz about Toyota, I can't help but notice you guys talking about 2T engine.

Is this a 2t engine?

 

[Joeker]

I took picture of the block no as well.

So is this 2T or 12T or wat engine?

Me still learning about all this TOyota engines. THanks.

 

[Joeker]

Picture of the engine before taken out.

 

[netmatrix]

Joeker that is one of the generations of T series engines. That is a 12T that u posted. But strangely the engine cover is same as my 2T-B. But i remember seeing many 12T using slightly different cover especially the re routed oil return. 12th generation T block engine.
Here is my crappy site to look at the 2nd generation T engine. Look for gallery 4.

But like zul said to me before, 3K better for track. heheh.

efini, yes can be bored out further. That is why they use 3T blocks. But big power engines like those...... i dunno if they could last track days or not. Maybe bore to 1.9 or 2.0 then take it to track. hehehe.

TE27 levins details on the engine mod looks very familiar. But then again many might be using almost the same setup with some secrets involved. hehehe.

I remember if u stroke or bore to higher capacity u can't gain higher revs. But u make up the low revs for torque. So 6000rpm and 7000 or 8000rpm means nothing if they generate the same torque for an engine. But everyone wants faster revs to reach max power for dragging.

Sometimes i dunno why i want to know so much, when i'm not using the info on my car. Silly me huh?http://zerotohundred.com/newforums/images/icons/icon10.gif

 

[LevinTE27]

kekeke.. the torque make 3T-C push rod run fast, not the rev. gear ratio plus turbo matching.. super b torque with good traction make interesting 1/4mile time.
wide power band dont make good time running in short distance, focus the rpm and torque at certain rev range will do. that the reason "Guai Lou" love 3T
