Howdy,

Can i fit a r33 powersteering pump to my r32, and just block off the hicas oil supply and return lines?

Im getting a Tomei hicas lock for the car as well, so dont need to worry about the hicas. Id like to keep all the lines and rear rack in the car incase i want to have the hicas put back at a later date, so is it ok just to block off these oil lines?

My r32 powersteering pump is making noises (not its not run dry or needs bleeding) its more internal whirring bearings....so instead of getting this pump reco'd or a replacement pump, since im removing hicas i tought this might be a better way to go?

cheers :D

Hi Bl4ck32, They are geared differently (check the pulley sizes), I guess because the R33 pump doesn't have to run the rear rack as well. Be carefull where you disconnect the rear rack plumbing as the power steering cooler runs of the return line from the rear rack solenoids.

Hope that helps

so i can just swap over the pulleys if they are different.

Nope not that simple, you really need to have a look at them side by side.

Where would be a good place to disconnect the rear rack plumbing then?

I removed the complete HICAS system from ours, it weighs heaps. Wait until you pick up one of the solenoids (there are 3 of them). After you have driven the car with no HICAS, you will never want to go back. As for the cooler I plumbed it in on the return line from the power steering rack to the reservoir. It's not under much pressure there. If you put it in before the rack it has to contain the full power steering pressure.

Hope that helps some more :D

Gotta figure out what i want to keep on the car then. The Tomei hicas lock uses the std rack, just with shims....easier to scrap the lot and use a lock bar i suppose?

How does this affect the computer? Ive got a PFC, so i dont know if the dash light will come on still. This was one of ther reasons i like the Tomei kit, due to the interceptor module....

We still have the R32 pump, I have been waiting for it to die but it just keeps on rattling. We use a billet alloy rear rack eliminator made by our race team fabricator. I pulled the globe, no HICAS warning light then. :D

Id just like to keep the rack and all lines there, incase i ever want it back on....ie sell the car or if im defected and need it on to pass inspection.

I suppose im gunna end up rebuilding the rb20 one then install the Tomei HICAS kit. I think that might be the easiest solution.....

you shouldnt need ever need it, if you do just put the rear rack back on with no lines too it for regeny, the 33 pump will bold streight up no probs, havent checked the pully sizes but hopefully i wont have a problem running with the rb20 harmonic balancer.

a complte new rear rack will only cost you $120 and be much more stable, i never had light in my car when i disconnected it all either

ever experienced the steering go stiff at slow speeds even with it disconnected?

My ps pump is stuffed. So keeping in mind i wanna diasble hicas later.....i can :

a) fix the rb20det ps pump on there now, then fit the Tomei lock kit

- or

B) remove the rb20det ps pump, strip hicas system, install r33 ps pump, and plug it up to use the ps cooler still, install a lock bar at rear

Im still running the rb20 harmonic balancer as well Clint.

      R33 GTR running -9 with no tune

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      By GTSBoy · Posted

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
