Sr Gearbox In An R32?

Hi everyone, this is my first post and I am looking for some gearbox advice. The box in my 3-2 is on its last legs and I am considering a conversion rather than a rebuild. The obvious choice seems to be the R33 box, but the cost of this conversion seems a little prohibitive and the speedo / trans-tunnel / driveshaft/ cross-member modifications strike me as being a lot of trouble.

I have my eye on a S13 SR20Det box and from what I have heard it will bolt straight up once the bell-housing is swapped and a custom tail-shaft is fabricated. Is this correct? Also, the speed sender is apparently compatible, so no modifications on that front either. My main question is if anyone has had experience with this sort of conversion or perhaps a similar conversion using an S14 gearbox? Would a R33 RB25De box be a better choice?

Any help would be much appreciated.

Cheers.

shifter position is different also.... not worth the expense. considering rb20 boxes go for 150-200 bucks.

i have about 10 sr and rb20 boxes at home i use for spares and they are weak as shit.

r33 or 34 or if you reaaly want 300zx are the only worthwhile conversion.

I've heard that RB20 boxes are similar to CA18s in terms of strength and that SR20s are stronger to some extent. My main reason for leaning towards an SR20 gearbox is how cheap an OS Giken triple gear-set would be several months down the track :(. But I guess I'll either have to swap in another R32 or go all out with a R33 gearbox. Thanks for the advice.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
