I'm using this 22 pulley and it goes on the middle shaft on the outside.

That's why i make an answer here regarding this 22 pulley

I hope you understood my explanations.

The 22t side pulley when used should be used with a 2mm split front to rear to keep the drive ratio 1:1. It is beneficial to run a small front tire on tracks with tighter corners as it gives a more agressive front response to the car due to a difference is roll centres front to rear and a more responsive tire with less sidewall. If you run a 2mm split your car is not considered to be overdriving, it is in fact 1:1 front to rear rollout, however your drivetrain itself is overdriven.

You can elect to overdrive your car using the 22t pulley and keeping the tires the same size front to rear, this only really works properly with a oneway up front. If you use a front diff there is a huge extra load on the drivetrain and the car will certainly handle "interesting".

well i have never used a cvec pipe on my cars before . i find that the novamega-rb - rex=top=max=pipe are pritty much the same. touring and 1/8 scale for that .12 engines and 21 engins classes. and i run both classes. skyline& ths pipes i will tey in practice.and let you know . but what you really need to do is tune the pipe that you want to use to the engine so you get max power when tuning .but make shore the clutch is right on your car so you can get it to the ground.

Sounds great. The oneway should be in tomorrow so I'll try it out.

AMG, I just got an email back from RC Champ about the 2005 parts

"Dear Mr.Imahara

I would think that the part number would be the same between the "2005" asia kit and the "Hara" US version. Maybe AMG could shed some light on this since he has the "2005" kit.

Well I know the kit numbers are different. 818 vs 816. But I did go check a website with the 2005 kit and they were listing the exact same numbers for option parts as the US. So im guessing it is the same.

So im kinda baffled why they arent available from hpi japan , but are available from hpi usa. Normally its the other way around.

Either way if you cant wait , buy hpi has them. Hope this helps.

Thanks for looking. I can wait. I really don't get a chance to race much, and my 1:1 project of buying/restoring a 1989 MR2 Supercharged is on the back burner (wife nixed that one). So, I'm upgrading my RC stuff. Maybe a 3PK and spectrum, 2005 spec R40's. Oh well. At least I'll look fast when I hit the track.

Lots to choose from , if you want all digital. S9550 is a good combo of speed/power and lightweight. Plus there compact so they fit better.

If you want regular , s9404 coreless. Want budget s3010 is strong for steering and s3003 for throttle would work.

Ive recently found a new servo to use. Well actually two of them. One is a ko propo , there new budget digital servo. Great price , and speed is great , only thing they are plastic gears..but I think the on-road will be fine with that. The other is some weird company which says they are just like either ko or futaba. Not sure but they are digital , strong and fast like a 9451 but cost 1/4 the price. Im going to order a couple of those.

Thanks for checking AMG. I guess we are just running into the parts/supply thing with the new kit, although HPI is usually really good about having replacement parts. I do seem to rember severe supply issues with some diff rings or outdrives with the pro3 a few years back. Like AI said, there's always buyHPI if I can't wait.

Possibly check with your lhs and see if they cant order them direct from hpi or something and hopefully can get you at least the regular mark-down from hpis full retail price.
