Hi all,

After installing my turbo and all supporting mods onto my RB20DET I was on the hunt for an aftermarket computer. After a fair bit of research, Power FC it was, but bugger me if I was going to spend the ridiculous amounts people want for an RB20 Power FC. So I looked into getting an RB26DETT Power FC modded to suit. After finding out that it could be done, I found the cheapest Power FC I could find (wrong idea) from Nengun. After a 3 month wait for it, it finally arrived. I then sent it straight on to BoostWorx in Adelaide to get modded and the RB20 map put into it.

The RB20 computer loom needs some modding before the RB26 Power FC can be plugged in, from the description it looked rather easy and a 10 min job. WRONG! We figured out a few problems with the wiring, it said to join different wires together in the computer loom, the problem was there was actually no wires in the RB20DET loom where they wanted us to join the wires. So we had to remove pins with wires that weren’t being used (aircon and automatic transmission wires) and put them into the correct spots that we needed to join for the RB26 computer.

After triple checking everything, we then hooked the battery in and watched for a minute to see if anything was going to fry, then put the ignition on for a minute and waited, then started the car…….it started first go!! Ran very smooth too and the Power FC was showing all the data it needed to!!

The only thing that I am checking up on is if an RB26 knock sensor will fit into an RB20 because the RB26 Power FC reads a lower knock when on the RB20. Say it is reading 30, it should be reading something like 60 because it is actually pinging, so at the start I will just have to make sure that it is reading nice and low on the knock reading.

It is booked in for the 11th for its tune, so cant wait for that!

All up including the modding the Power FC has only cost me about $900 so I am rather stoked.

Joe.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p

      Bonnet clearance?

      Magnetic Drain Plug Snapped in Half

      On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.

      So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.

      Finding E-30 & E-85 in Sydney

      By GTSBoy · Posted

      This seems like a pointless exercise. There is no E30 availability. Ongoing availability of E85 should not be assumed. Flex-fuel is the only sensible approach, so you can use E85 when and where you can get it, 98 when that's al you can get, and anything in between as you fill it up and drain it down. And if that means replacing the pumps, fitting a flex capable sensor/ECU/whatever has to be done to these Renault shitboxen, then.....so be it?
