18r-c into ta22

[jezza289]

hey
ive bought a ta22 and the 2t in it is a bit tired and smokey.
i got given a carona hatch with a rebuilt 18r-c in it and i was just wondering how hard
it would be to put that into the celica. and would the celica 5spd bolt straight up, what engine mounts etc
cheers jezza

to put the 18rc into the ta22 you need to have the right sump on your 18rc forget which one and move your mounts forward by 100mm. I did this by wleding plate onto the engine mount and some supports. If you move the mounting point 100mm I had no problem blting up the gear box also.

the 18rc is nothing but a powerless, reliable engine .

for all the effort why not fit a 18rg?

[stradlater]

The answer is - because he HAS an 18rc that works.

I think you'll need a W40 or W50 box, As from memory the T50 box doesn't adapt to 18R's without a custom bellhousing.

A lot of it won't bolt up, are you up for custom work? welding?

[stradlater]

It is gonna be a bit hard mate, probalby not worth the effort.

[jimmy_a]

Definitely not worth the effort.

Hi,

Yep, not worth the effort.

You're going have to get the engine fitted into your engine bay, and as it's a R-series engine it will need sump and mount changes. Also, you'll need to put in some adapter to make sure the 18R-C can connect to your T-series gearbox.

I think it's be best for you to either get the 2T fixed, or whack in a 2T-G. I think the 2T also generates a few hp more than an 18R-C... so you're going backwards in the power department, and cost.

get a 3T-GTE :-)...

[jimmy_a]

3tgte Ftw!1

[myne]

Why?
Even a 3T is a HUGE 8 valve monster with a mere 160hp (std)
There are literally a dozen really good, newer motors that will provide a far more satisfying upgrade.
Everything from a 4efte, 4a/ge/ze/20v, 3S/gte to other marques like the Honda F20C, Nissan CA18/det, SR20, to the larger 1MZ, VG30 or even 1uz.

I cant figure why you'd go to the effort of installing something that was cast from wrought iron in the foundries of the first civilisations in the days when the earth was believed to be flat.
At the end of the day, you've got a great museum piece, but an uninspiring engine.

[stradlater]

You can bolt a turbocharger the size of a house onto the size of a 3t-gte and it'll stand up to it..

Do that with a Honduh motor...

[myne]

Well, I'd be guessing the 3tgte is ~the 6psi mark, and that's just over 1/3 of a bar.
So we can make a fair assumption that it's getting nearly 30% more power over the stock 3tge.
So the stock figure of 160hp/3*2 = 106hp - which is actually a bit generous, but hey, I'm feeling nice.
Now, up that to 1 bar. You're likely to get ~200hp.

Now, lets take a similar sized honduh motor. I'll play nice and take the B18A - a 150hp NA, non-vtec 1.8L twincam.
Now lets add a theoretical safe maximum of 10psi. That's 2/3 of a BAR, and with some luck we'll make nearly 2/3 more power.
What's that? 150 + (150/3*2) = 250hp -15hp for inefficiencies and you've got a 1.8L turbo of a nice 235hp.

Ok, so lets match that 235hp with the 3t. If 15psi (1bar)= 2x the power, then 21psi(1.3bar) should be about 2.3x the power. Call it 235hp.

Sure it's all theory, but meh. The 16v is more efficient. There's no escaping that. It doesnt matter how big the turbo on the 3t is, it's always going to be harder to make power.
Sure it's tougher, and might even handle 2 bar, but what revs will that finally spool at? And how long will the power last? 2000rpm?

[lumpy]

The biggest problem with your example here myne is not really one of engine design, it's one of logic/human nature.

I suspect the reason that "turbocharged honda" and "catastrophic engine failure" are often mentioned in the same paragraph is twofold.
1. 10 psi is not a theoretical safe maximum,
but more importantly...
2. How many turbo owners are happy with the original/standard/first run boost level? Bugger all, so when you want more power you turn up the boost until ricky martin comes on the radio shouting "she bangs she bangs" with the honda but if you'd stuck with the initially slower 3T all you'd hear is maxi jazz from faithless going "I want more" ....

Plus I imagine one is much easier to install than the other
