Im about to convert my r33 to manual but dont want to fork out for an rb25det g/b and want to use an rb20det box instead because they are about 1k cheaper and still quite strong and the car is unmodified.

Has anyone else done this?

I know it will bolt to the engine ok, but will the cross member line up?

Also, is there a way to change the r32 box's cable speedo drive to electric?

Any help greatly appreciated.

you'd have to be mad! the second gear is known to be quite weak for starters and I've seen 3 of these boxes wrecked behind a cefiro and 2 different jap R31's, thats not with sustained abuse at all either. They are apparently only about as strong as the MF5 gearbox which is used in the non turbo VL.

It might not help you with the orignal post, but its such a silly idea in the first place, i doubt anyone's been foolish enough to actually try it,

Don't be a tightarse and just get a R33 box.

the 32 boxes are the same as the vl's... bar the gear heads are larger and can take a bit more of a beating in the 32...thats what i'm told anyway...my 32 box has been through some tough times...doesnt crunch, grind or be difficult to get into gears... that said i'de rather a 33/34 box, nicer feel and stronger...

    • I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?
    • Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?
    • So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good
    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
