I've gotten myself a cefiro. Its currently running the single cam non turbo automatic RB20E and I'm looking at converting to 5spd blacktop SR. I've been able to find a little bit of info about it but I'd like to talk to someone who's actually done the conversion before, so I can confirm what needs to be done before I set out. So if you or someone you know has done it, let me know please. Also, if you haven't done it but just happen to know something about it, I would like to hear that too.

Cheers for your time.

It's a very easy conversion, just been a couple of years since i did it.

red top sr and box into a cef requires the use of an s13 crossmember and power steering rack. (get a lock bar for your hicas and remove all the solenoids and lines while you're at it). I'm fairly certain that the s13 tie rods are used aswell.

Gearbox crossmember needs to be modified to sit slightly further forward (or back, cant remember) to line up with the bolt holes in the cefiro floor.

Gear stick hole needs cutting and the gear stick needs to be modded to sit it in the right spot (but this isn't essencial).

And as per usual, wiring is the fun part, but you can modify the sr engine loom and pull the power for everything off the 4 pin plug in the front passenger side of the engine bay. Wire in the eccs and ign relays next to the ecu in the same way the rb loom has them. You use the rb body loom section on the sr. Some plugs need changing to wire in the neutral and reverse switch.

Swap the rb20 speedo drive into the sr box.

I'm fairly certain an s13/14 clutchmaster cylinder is needed to clear the inlet manifold aswell. Some bending of lines and a shortening of the threaded section at the pedal is needed to maintain the range of adjustment.

Then just wheel alignment and s13 front pipe and a bit of custom work around the cat converter and it'll be a runner.

Tacho will be out of wack though.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
