Upgrading mp 7.5 kyosho
I bought this car off of amainhobbies a couple weeks ago and I'm fed up with this engine.
amainhobbies.com/product_info.php/cPath/1_44_48/products_id/149504/n/Kyosho-Inferno-US-Sports-4-Type-1-Ready-Set-Buggy-MP-75 I'm looking to get the N21R-bf and a jp-3 pipe but I am having trouble figuring out what else I'll need. I read that I will need motor mounts and possibly a new clutch and spur gear. is anyone familiar enough with this car or know what I'll need? I don't want to blow a ton of money at once, but this gx21 is horrible. what do I need right away and what should I plan on buying asap? thanks in advance |
Where did you hear you would need a motor mount? Assuming you have the mount the kit came with you can use that. As far as clutch, does it have the old 2 shoe clutch or something more advanced like a 3 or 4 shoe clutch. Either way the clutch you have will work though if you have the 2 shoe i would upgrade but it is not required. You really shouldnt need anything but the engine and the pipe you want to use.
What exactly is wrong with the gx? I dont know much bout them but I am sure someone here can help you get the most out of it. |
This you gonna need:
For exemple this one- http://www.amainhobbies.com/product_...-3-Ergal-Shoes This you have to buy- http://www.amainhobbies.com/product_...d-Engine-Mount And probably this- http://www.amainhobbies.com/product_...Replaces-IFW47 And i think thats all. Cumps |
done the same thing years ago, the standard engine is bolted on the chassis with the crankcase, so you need new mounts:
this: http://www.amainhobbies.com/product_...d-Engine-Mount & http://www.amainhobbies.com/product_...Plate-Gunmetal scews to secure them: http://www.amainhobbies.com/product_...Head-Screws-10 new clutch setup: http://www.amainhobbies.com/product_...lutch-Kit-34mm clutchbearings: http://www.amainhobbies.com/product_...ch-bearings-10 shims: http://www.amainhobbies.com/product_...lutch-Shim-Kit and possible a new bell: http://www.amainhobbies.com/product_...Replaces-IFW47 |
Thanks for all of the help, it's my first time upgrading a motor and it was pretty annoying trying to find info on it.
Do i need both of those motor mounts that you mentioned Matthijs? @barry - the GX21 is constantly either overheating or stalling, I can get it to run consistent but at that point it's way to rich and just a dog. I've read in a bunch of different forums about the problems with it holding a tune, so I'm jsut going to upgrade it i think. |
