hey guys!

im new to this forum but im sure not new to this hobbie. i decided to join this forum cause the one i was on was slipping in numbers a bit. anyways... i am wanting to put a big block engine into my mt2 and i am not sure which engine to go for( must be a SG type crank shaft ). i am sure that there is lots of stuff about this in the official mt2 thread but to be honest i really cant be bothered reading through 466 pages just to find a small topic. i am currently eyeing up the hyper 21, which doesnt seem to be a bad price at £84 (thats about, $162). i know that may seem expensive but everything is in britain. i will order over seas if it substandually cheaper in the US. i am wanting opinions and other suggestions as to what engine to use. i already know where i am going to get all the parts i need and i am well aware of what happens when you put to much power into something designed for small block. i am currently running the car pretty much stock apart from the normal bits like airfilter and such... the only real change is the servo's and the masher 2k's. i am also interested in what gearing i should use as i am not wanting to be buying loads of diffent sets of gears just to experiment ( waste of money) bearing in mind i am one for the good old wheelie on demand. any help would be greatly apriaciated.

Cheers

Chris

I have a MT with an OS.18 TZ which good chance has as much power as the engine you are talking about or maybe even more but is a small block. Since putting the TZ in I have spent much time working on getting where I can run more then one or two tanks of fuel before tearing up the drive train. Have not gotten there yet but I am gaining. Good luck and make sure you buy plenty of extra drive train parts particularly the high dollar final gear sets. If you have the RTR you will have a lot more to do to it then if you have the SS. If you look around you will see I am not the only one having this problem with a high out put engine. Yes it can be done but get ready in putting as much or more in to beefing everything up as you will in the engine. I have been running my MT for 4 years. It is not a MT 2 but a MT 1 ¾. Just put the TZ in a couple months ago.

One other thing had to gear mind way up to keep the front wheels on the ground. I recommend if you what something for wheeling get a Savage as you probably will spend as much or more on getting the MT to hold up and do the conversion as what a Savage would cost. I have both a MT and Savage among others.

i have all the drive chain bits sorted. including the final gears. i have all the nessesary bit on order. i have just been looking around the net though and i stumble upon the hyper 12 which seems to be extreemly cheap for what it is. it comes with the sg shaft and the slide carb but would this be powerful enough to move an mt2 with mashers?

Do you have alloy differential housings? Make sure you shim the differentials properly. Do you have all the heavy duty CVD, heavy-duty drive cups and center dog bones like on the SS? Do you have the big block conversion kit or are you going to make that? Buy the time you buy the conversion kit and the engine might be better just getting a TZ.

yep all of that is either here and ready or on the way i think i may just buy some nig block engine mounts and drill holes in the chassis but it would be so much easier to just bolt them in. im not sure on that on yet. if i was going to order a conversion kits it would have to be frmo the states cause nobody makes them here in britain. would it be possible to make big block engine mounts that would srew into the provided holes? has anyone done it?

Yes you can make your own conversion if you have the right tools, machines and the know how. All so keep in mind you will need a different flywheel and clutch set up and exhaust. If you are going to drill your chassis make sure you keep everything in line and parallel. What brand alloy differential housings do you have? Well guess you will have more in the MT then you would a new Savage as all the pars I was talking about not counting the engine, pipe, flywheel, clutch, has to be around $200 or more. Good luck and start posting pictures.

i know a guy who works for american cnc and he made a custom design for his own mt2 with the differencial housings and also the upper deck. so he said he will do me a set of them for only the cost of the metal hopefully he will come through for me and deliver. otherwise i will have to shop elsewhere for diff housings[]

and also i plan on using a savage set up for the flywheel and the same for the cluch and clutch bell.

There is a guy I talked to on the Savage forum that has a HPI S25 in his MT from the UK and is having many of the same problems as I am with drive train. The TZ in my MT is really way too much so I can image what a good BB will be like. Coarse the TZ has as much HP as some big blocks. If I had it to do all over I would have gotten the OS 18 CV-R or RX. I have my truck geared REAL high and still is a hand full 15 CB and 47 spur. I use to race my MT but now just play around with it and race my Savage and Hyper 8, as the TZ is too much for the small tracks around here. The only differential housing I have found is the GPM junk. I hat GPM but cannot find any other ones. If you do let me know and all so see how much your friend would charge me to make a set if he ever gets yours. Good luck and post pictures.

One other thing do not use stock Savage clutch shoes, as I know from experience they are not real good. Might be better in a light MT but in a Savage they are about worthless.

i was just looking on ebay and i have seen some pretty good aliminium clutch sets for the savage flywheel, are these any good? they seem to be custiom made ones not brands. i have just spoken to my mate and he says that he is having trouble finding the correct sized peice of alimnium for the job. but he is definatly making the upper deck wich i pretty nice. ill get some pics for you asap. the diff cases aint lookin to hopeful, but fingures crossed[]

Right now in my Savage I am running a XTM sliding clutch but the shoes seem to wear fairly quickly. I all so have run the Nova alloy shoes and they lasted about 3 gallons. The only problems with alloy shoes are they take a good bit of maintenance. You have to keep taking them out and filling the burs off where the alloy folds over the sides. Watch out as some alloy shoes are good, some are OK and some are just not worth it.

shouldnt the stock savage ones do the job well on the mt2 though? i mean the savage ones will obviously take more of a beating cause they are trying to tur those big ass tires round not to mention the weight of the thing. with the mt2 being so small and light shouldnt it last alot longer?

Try it and see, when I was breaking in my Savage not running it hard as I was breaking it in the sock shoes slipped so bad the CB got hotter then the engine and melted my Spur. Put the alloy Nova then the XTM in and since have way over 7 gallons and have not had a spur problem since.

thats sounds like crappy clutch springs then. if it was slipping so much then they mustve been crap springs.

If you go to the Savage forum you will see this is a common problem with the stock shoes. Has nothing to do with the springs as the springs only retract the shoes. I put the alloy shoes in with the same springs and did not have a problem! The alloy shoes hook up great. Like I said go to the Savage forum and look around. [8D]

how is the orion crf v6 clutch? have you tried it? i read that it is an exellent big block clutch.

That is what I have heard to but for less then 1/3 the price I rather go with the Nova or XTM sliding clutch. I have been told there shoes last about 3 gallons as well and the shoes are not cheap.

do you have a link to the nova or xtm clutch's?

Nova even has a phone number for the UK!

What I like about the XTM clutch is there is no maintenance but the shoes do wear out sooner but the good thing is they are only about $10 a set.
