I thought I'd share my latest project with you guys. Started it a week or so ago. With parts availablity getting tougher for the Vmax-4 motors I decided it was time for something a little newer, RX-1 motor. The plan this year is to hit it with a pretty big shot of nitrous and then next year I will build a turbo setup for it.
The frame has been chopped, need to finish boxing it in still. Had to chop up, lengthen, and narrow the steering stem, then bend up a custom tie rod to clear the motor. The motor mounts are finished, the rears are simple aluminum angles and the fronts are made of 3/4" chromoly tubing. The CDI, volt. reg, and oil tank are mounted. We relocated the radiator and just need to finish the plumbing. The exhaust is only partial but I have a plan for it. Hoping to be able to fire it up within the next three weeks, but I still have a bunch of little odds n ends parts to get from an RX-1.
What do you think?

I've been looking at the pic's and WOW you sure have done a lot of fab work so far. What are your plans for the exhaust & Seat?
Working on exhaust this afternoon. I'll post up some more pictures later. For this season it will drop into one shorten cherry bomb and then dump through the tunnel. The seat has already been redone a couple of times, I'll just take it back apart and build a tunnel in it for clearance. When the turbo goes in it we are planning on sending the exhaust right out the side panel in front of the seat.
Thanks for the compliments!

Got the exhaust done, tunneled the seat and got a clutch cover done up for it today.
That's cool, Great Job!

Master, that is great project!
I remember seeing a RX-1 motored Vmax on the Vmax4.com too. That one was from Norway.
Keep the pics coming.

Imagine that, Master Faster building a sled! lol.... Looks great! Can't wait to see more!
Small update, fuel system is all figured out, mounted the tank, pump and regulator. Cooling system is pretty much done. I didn't want to mount the motor too far to the left side of the sled so I had to machine the jackshaft and the secondary side bearing mount to move them inward to get the clutch offest right. Pretty much all the mock-up stuff is done so I'm going to pull the motor back out, get the frame welded up and then start putting it together for good. Should be making some noise in no time.

Coming along nicely. I got the frame all boxed back in, the motor is finish mounted and aligned. Fuel and oil systems are completely done. Battery is mounted. I need to pick up one elbow and the coolant will be done. Wiring is about 90% complete, just gotta make a couple battery cables and wire the temp sensor. Waiting on a couple exhaust gaskets and should be able to fire it up within the next few days, possibly some test passes next weekend.
