Questions?? Pls look. Need help from you Mugen heads

I couldn't find the proper forum to post this, but here it goes. A buddy of mine blew his 1/8 onroad MR21 motor a few days ago, and in the process, damaged his piston head. I've tried to help him look everywhere online to purchase this part, but I've had no luck whatsoever. Rather than perhaps going to the manufacturer directly, does anyone know he can purchase this part from a 3rd party seller? Your help is greatly appreciated. Thanks for looking.

Measurements from end to end:

Front:
All the way in ==> 59.50mm
All the way out ==> 69.00mm

Rear:
All the way in ==> 61.50mm
All the way out ==> 70.00mm

I would say that they fit OK, since the first version of RX8 was a direct copy of MRX4X and MRX4 and 5 have the same dampers.

Share the results for us also if you try it??

What belt is he after because they didnt change the belts until the MRX5. Now the only belt that is the same is the rear belt the rest are new to the MRX5 so if it is the side or front belt then you can use an MRX4 one and I think all the pullys are the same from the MRX2 to the MRX4 except the big rear one. Hope that all makes sense.

Hi there,

did someone play around with shock piston holes and could share the findings?
For example front 1.3mm holes and very thick oil to compensate?
In theory large holes paired with thick oil should give the same low speed dampening effect but smoother high speed (over bumps the car should be more forgiving).

Thanks a lot and best regards!

With 1.3mm holes, I use mugen 450. My home track is high speed, flowing, have few bumps and dont have smooth surface.

I think you should try mugen 600 as your starting point.

OK, thanks a lot for sharing this information.
Are you pairing this with stock pistons in the rear and 600 oil? Ever tried to drill bigger holes in the rear?

I use 1.3mm piston hole front and rear.

450 front and rear too.

I cant comment the road feel with drilling bigger piston hole questions yet because i havent try it yet. I have spares oil damper drilled to 1.5mm inside my tool box. However i havent try it yet.... I think you should try 1.3 first (try stock as is).

I am getting ready to run my MRX-5 WC for the first time, but before I do, I was curious if there was ever a resolution to the side belt problem. I tried a search but found more people talking about it, but not much in the way of fixes. I have the front belt around the right tension and as a result, with the side tensioner down all the way, the belt is still very loose. Just curious if there was a quick resolution to this issue so I don't end my day prematurely. Thanks.
