Put an sr20 in it, best thing for it. Done all manner of rb conversions into 180sx's up to S15's and honestly the SR20 is the best option. We have a 430rwkw RB26 in our s13 and i wish it was a 2.3l SR20..... RB's and S-series chassis means POOR weight distribution and all manner of other issues.

thanks trent, but has i am wrecking my r33, i thought i could just use the running gear from it and put it into a 180sx, it will just be a daily driver, so it will be kept fairly stock once the conversion is done

you need to use the lower cross member, (i prefer to use r32 x-member and r32 engine mounts) and matching mounts, massage the firewall / tunnel to fit the box in, section the front rad support to be able to fit clutch fan (most reliable way) Front facing plenum makes the bonnet shut and allow a strut brace. the rest is pretty simple other than wiring as the R33 sources power from inside the car whereas the s13 power supply is behind the lh headlight. Its not a wiring job for a novice but its fairly easy if you understand the circuits. We used to combine both rb25det and s13 harnesses to make it a full plug in operation, but now i don't do any conversions as its too time consuming.

I have a rb25det conversion dvd that was sent to me as a sample many years ago, ive never seen it but your more than welcome to drop in with a blank dvd and ill burn a copy.

Weight distribution can be dealt with aswell as the cooling issues... I say go for it power to wieght FTW!

I'm helping my mate get a 25 into silvia in the next couple of weeks when he has finished getting parts

Handling can definatley dealt with but not fixed, having 3/4'sof the engine in front of the front axle centreline is probably the WORST mod imaginable... :)

For the cost of a RB25 conversion one could build a SR23 that will exceed both torque and power of a rb25..

In this case he already has both cars so it wont be as expensive.

      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?
