Rb20Det Valve Spring Upgrade.

[RedDrifter]

I have decided to go with new cams very shortly and I wish to up grade the valve springs as well (for Peace of mind).

After some research I have seen how you can put compressed air into the cylinders to allow removal of the springs with the head still on the car.

I just need to know what tools everyone recommends me to use for doing this.

I found this http://www.toyotool.com/PURCHASE.htm

Which is the correct sizing for the RB20DET?

Has anyone used this before and is it as easy as the video shows?

All help is appreciated.

I'd be very suprised if there is a tool to get the springs out of a skyline head while its on the car. Yes you can put compressed air into the cylinder and hold the valve shut while you wind a clamp like tool up to compress the spring. The problem is with these heads the springs sit down inside and you won't be able to get the clamp down onto the sides of the spring. Any cars that use shim buckets have the same problem.

From when I looked into doing it, you supposibly had to make your own tool to do it. Every one I spoke to that had done it said was a pain in the ass.

Hence I just ripped the head off.

I ordered a Lisle 36200 valve remover from the US and it should do the job. There is a vid of a using it on a 300zx head and there valve springs postion are similar to those on RB25 dont know about the 20s

You mean this tool ?

Looks almost identical to the one in my first post.

300ZX and rb20 / ca18 use same valve springs and hydrolic lifters etc so I assume it would be perfect for the RB20.

Yeah thats the one, yeah if its same then should be no probelms. Theres a dozen of these removers all different brands but same design. Mines should be arriving in a couple of days.
