Hi, yesterday I installed an R32 GTSt (RB20DET) power on my R32 GTS4 (RB20DET). I removed the vanes from the back of the pump and blocked off the rear chamber as I have removed the rear steering.

The steering seems ok until I steer to the right and the quickly to the left (or vice-versa). I get a very large amount of lag, that is the car doesn't steer in the second direction.

What could the problem be? Failed pump (might not be because it steers well the rest of the time), failed steering rack (didn't do it before I changed the pump), maybe it is the steering fluid?

Any help would be great as this sucks.

Sounds like a loose bolt somewhere. Check all of the bolts to do with the steering including rack, the steering wheel shaft, that bush inline with the steering wheel shaft, all of teh bolts at the hubs.

If not, sounds like there is alot of play in the rack.

Let us know how it goes.

The problem seemed to go away after about a day. I guess the system had not bled it self fully yet.

The steering seems a little heavy - but it is consistent so I am happy. Thanks for your comment though!

    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
