Rb26 is still nearly 1/2 a litre less than Rb30, torque is still gona be a fair bit less.. All 3 boxes i destroyed had stripped 3rd gear, every time it happened i was accellerating hard in 3rd, then BANG.... One decent R33 box is cheaper than several Rb20 boxes.

just curious how would this conversion go in a A31 Cefiro? and gearbox wise i've heard that the best gearbox to use for a cefiro drivetrain conversion is a VLTurbo MX7 gearbox because it runs a cable speedo drive? and out of the MX7 and the R33 which is the better box would they handle alot of power and which one 'feels' the best for those with experience? cheers

do a search for how much they are. (~$1500) You just need one in good nick and it will last. No it wasnt difficult to put in, because i bought the setup out of another r32 (came with tailshaft modded, gearbox mount, and speedo drive modded)

Yes, i was running the rb20det b4.

heard of that. ;) They say because you are driving the car on SA roads, YOU are still responsible for it. They still defect it no matter what....

Nope, Commonwealth/State Law doesn't work that way, if the car is legal in Vic they can't defect it in SA. Take the defect sticker off and post it to them, with a thank you note of course.:D

The R33 gearbox feels alot smoother than the MX7. Most MX7 boxes have got high kms on them, there usually noisy and notchy to shift gears.

I used the stock r32 tailshaft and got a VL turbo yoke (or R33 turbo) welded on the front, overall length was the same.

SAPOL do what they want Gary...they can defect a car with interstate rego, and have done before.

 

Sending them the defect sticker will result in a nice fine as well....

I don't care who they are, they can't issue a defect notice on a car that is legal in the state it is registered in. This was tested many years ago in the Federal Court, Queensland had different registration laws with regard to extra lights. NSW tried to defect the trucks carrying the extra lights (that were legal in Queensland), they lost.

This case (and few others) is the reason why all the States signed the national agreement on common ADR enforcement as provided by DOTARS. SA has broken that agreement, if anyone takes SA to the Federal Court they will win.

A copy of the agreement is availabe under Freedom of Information from DOTARS.

:D

Im on your side Gary...when I get my car finished i'll be taking it interstate to more than one place to have all the ADR tests etc done to make sure its legal....

Ive had a cop on a bike pull up next to me and say "if i hadn't just worked a 13 hour shift, i'd defect you for your blow off valve". Then the lights went green, and he took off (from a right hand turning lane) and pulled infront of me to continue stright down the road.

Now without seeing my enginebay, how did he know i had a blowoff valve? And yes I do still have the STANDARD blowoff valve installed in the car.....WTF!!!

Its a revenue raiser for SA, and things are not going to change here (cops issuing defects) until this state gets WOF checks like other states. Until then they do what they like.....have a read of the regency thread in the SA section to see the BS they have gotten away with...(defecting ADR approved steering wheels etc)

I havent had any trouble with them as of yet (touch wood) but believe me i will be taking it as far as i can if and when the time comes....

/end rant....back on topic :D

Picked up my bottom end today, pretty good score i believe! Its a 1988 R31 bottom end with only 168,000kms! Looks to be in great nick, will start taking it apart soon and giving everything a good clean and inspection. Manged to score it for $150

Finally the journey of the RB30/25 begins! (8/4/05)

I guess we'll see how long it takes but i know that i can't wait to turn over the key!

      R32 GTS (RB20DE) clogged cat

      By MBS206 · Posted

      The hot exhaust light will come on not from just the cat being blocked, but it's just a temp sensor, and it's designed to warn you to not do things like park in long grass.   If you've been pushing the motor a bit, it can cause the light to come on.   Second if the cat is rattling, I'd suspect it's not blocked, but instead falling apart inside.   The easiest "fix" until you can get a cat put back in, is to unbolt your one, bash the rest of the insides out, and then bolt it back in.   For a daily driver/street car, I am in agreeance of put a cat in the car. If it were race car I wouldn't care if it were removed.

      No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️

      Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney

      I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"
