Helloooo

wonder has anybody tried this before

FairlyNew

Yes, it has been done and fairly easily. There is an article on it here.
http://www.terracrusher.net/
it has a great walkthrough on how to do it.

here is another great Terra Crusher site
http://www.terra-crusher.com/

I have also looked into this engine for my terra crusher. Once the stock engine goes out I will replace it with a more powerful one.

I think I will go with the new era .21 conversion. The reason I will do this is price. Its only $50-75 more than a just a sirio engine depending on where you get it and it includes all the parts. The sirio is an awesome engine but so expensive. Then you add all the parts like flywheel, T maxx clutch and bearings, it will almost equal the price of the .21 conversion.

New era has a .21 conversion WITH engine, chassis, motor mount, bearings, flywheel, tuned pipe and all linkage for $275 the motor is a OFNA Picco .21 (2.2 hp).
You can upgrade the package to an OFNA .21 Hyper 8 port for $20 more(2.5 hp)
Here is the link to new era

They also carry a full line of aluminum parts for the Terra Crusher

I am in no way knocking the Sirio 18, it is AWESOME, but I like the ease of getting a kit that has most of what you need. I have always wanted a big block too.

There are also people that have put the trx 2.5 in the Terra Crusher with very little problems. You can find those on ebay much cheaper than you can find a Sirio 18.

Good luck to you and post if you change your engine so we can see it.

you do know the sirio has more power than most basic .21's out there? Unless you were going to get something a lil fancier, the sirio would be your best choice IMO.

But why is it there 's a need to take out the reverse function when putting in a big block engine ??

The Sirios aren't that expensive either. Our LHS sells them for $189. There are quite a few .21's out there the Sirio will outperform.

Taking out reverse is a pretty popular option for the Terra. The way the frat auto transmission works on the Terra creates alot of clutch slippage. The slippage is there to cushion your forward to reverse transition and allows use of a 2 channel radio for forward/reverse shifting instead of a 3 channel like T maxx. I.E. you dont go from 30 mph forward and hit reverse and break something. By going to a forward only conversion you can get rid of alot of that slippage and guys say it is like a whole new truck. That has been the only dislike I have with my Crusher, not enough low end power due in part to the trans setup. Once moving its great. There are some articles that tell you about all this on the links I posted above. I still like reverse so I can deal with the slight loss of low end. Who knows what I will do when my engine goes out.

Also some guys have even gone to a .21 conversion on the stock chassis with just a little grinding on the chassis plate and a slight relocation of fuel tank and one of the rear right hand shocks.

Good luck to you.

Also there are currently 2 Terras on ebay with .21s in them
