Which 18TZ for MT2?
I know this has been covered, but after all my searches and reading online I have found more questions than answers. I am buying an 18TZ for my MT2 and need to figure out which one to get.
I know I can't use the short shaft, but can I use wither the pilot or SG style shaft one? I've looked at the pictures of factoryengines on Ebay and it looks like they come in bothpilot and SG shaft conficurations. I want a bump start and rotary carb, but it looks like it's not an option? Can I convert the pull start model to a bump start with just a backplate swap?
Thanks in advance.

OS is retarded, they offer two models... pull start rotary carb (std shaft), and non pull start slide carb (SG shaft). These are the only two models for some [extremely retarded] reason. You could swap the back plate, but you would have to grind the nub off the crank, and it would be standard shaft. These engines are also turbo plug. You could order the non pull start crank (SG), and not have to grind the pin. The motor itself is $200, then another $50 for the crank, and like $10 for the back plate. You could buy a better motor for that much, or convert to big block.

CVR .18 is all the power you will need anything more is overkill

You need the long (std) shaft version. It will bolt directly in. ThunderbirdJunkie recommends replacing the stock pipe with the Associated torque-tuned pipe, or the Associated Smoothie.

By long are you regerrring to the SG shaft? I don't even see that one listed as an option on the TZ though, that's why I'm so confused...

Yeah... the 18tz doesn't come with a long std shaft. You can use the SG shaft, just get these two things.

I agree the CVR has some good power, but this MT2 is set up for 100% on road, high speed driving so I really want to stick with the TZ. Plus I can get it with a bumpstart backplate already.

Oh, trust me, you won't want for more power with the CVR. You can also get a CVR with standard crank, rotary carb and no pull start if you wish.

Make sure to break it in long and easy, its VERY easy to ruin a CVR.

Do you do the typical OS heat cycle method of idlig it for a few tanks and then driving it?

RE: Which 18TZ for MT2?
Yeah, I'll call BS on that. For starters, a square head CV is about the furthest from a race engine as you can get... so a "race tune" would require you to run it dangerously lean. One of my first cars had a CV, I did not head the instructions and drove it around after idling half a tank, lasted about half a gallon before it had zero compression. Not mentioning the fact that the new CV is designed completely different than the old ones.
Edit: A heat cycle is not required, but a good solid 6 tank idle is. Do not let it run out of fuel, when it gets low, press on the air filter to kill the engine (only stop the engine this way when the filter is clean), you can also use your shoe or something soft to stop the flywheel. Do not pinch the fuel line, this leans it out. Heat cycling is letting the engine cool with the piston at BDC between tanks, again its not required, but makes for a better break in.

A square redhead 12CV is NOT the same thing as a .12CV-R
and if you want to pick nits, a .12CV-R isn't even close to a "race" engine either, compared to what's out there now.
The point is simple...you don't know things[&:]

RE: Which 18TZ for MT2?
Go with the tz model you will not find a better model than the tz, the cvr is a good engine (and i know I will take flack for this) the cvr is no where the engine
the tz or the tg is!!!!!!
The tz is nasty fast I mean naasstttyy fast quick response great top end...
The tg is a little slugish on the bottom but on the top end it is tons of HP....
I have had all of them the tg and tz are the best, do the change, the slide carb tops the roto. hands down, it is worth the money if that is what you want to do.

Eh, doesn't really matter what kind of OS engine it is, whoever says it runs 6 gallons without a break in is a liar.

RE: Which 18TZ for MT2?
I broke in my 18 CV-RX by starting it, then gently driving around for 90% of a tank to ensure it got up to temps. I then shut it off by plugging the exhaust, refilled the tank, let it cool, then repeat four more times. That engine today still runs great and I've got about two gallons through it.
