260DET Posted February 1, 2008 Share Posted February 1, 2008 The big Nissan turbo box, the FS5R30A, is virtually unobtainable in AU but the Z32 box is readily available. So I'm wondering if the Z32 box will bolt up to the single cam VG block. I know that the shifter is different but thats not a problem. If it does bolt up are there any other considerations? Basically I'm looking at building a big power VG30ET but without a suitable gearbox its not a proposition. Quote Link to comment Share on other sites More sharing options...
Clifton Posted February 1, 2008 Share Posted February 1, 2008 The VG30 trucks got the same big trans too. The shifter is top mounted like the Z31, if that's what you are looking for. I would assume the twin cam and single cam VG engines would use the same bellhousing pattern as they are the same family, but that's just a guess.

Guest TeamNissan Posted February 1, 2008 Share Posted February 1, 2008 Ya, I would think they use the same bellhousing as well. Beyond them being the same family aren't the blocks identical? I could be wrong but I'm 95% sure they are. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted February 2, 2008 Share Posted February 2, 2008 Bell housing is the same though the starter placement of the Z32 5-speed is different (mounted on bell housing compared to mounted next to the block on the VG30ET). The DE(TT) uses an 8 bolt flywheel while the E(T) uses a 6. You can however mate them together. You'll need: 89-91 Nissan Maxima 5-speed flywheel 84-86 300ZX Turbo or 85+ Maxima clutch Z32 NA 5-speed (TT 5-speed can be modified to work (starter pad)) Z32 throw out bearing Z32 starter Lower Z32 engine to transmission brackets (if I remember correctly, I'm pretty sure these can be used) That will allow you to bolt the Z32 5-speed straight up to a VG30E(T) and will work perfectly. Was running that setup in a 91 M30 and am going to run it in a Z now. The shifter setup is different if I remember correctly. The Z32 uses a bracket that holds the shifter and has a piece sticking out of the back for the shifter to connect to. It sits further back I believe but what's nice about the bracket is its easily modified to just about any length you need up to putting it right against the shift "rod" sticking out of the box. Here's an aftermarket solid shifter bracket on the Z32 tranny (stock shifter placement though): (Pictures are a bit big so if you have a slow connection it may take a bit) http://www.machzracing.com/M30/Drivetrain/SSB2.jpg http://www.machzracing.com/M30/Drivetrain/SSB3.jpg Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted February 2, 2008 Share Posted February 2, 2008 Very informative, def saving this post. thnx Quote Link to comment Share on other sites More sharing options...
260DET Posted February 2, 2008 Author Share Posted February 2, 2008 Yeh thats good info, thanks. Have a DETT flywheel, clutch and crank that I'd want to use, mainly because the flywheel is a custom steel job and the eight bolt setup would be more secure. The next thing to look at would be crank snout fit I understand, might wait until a W series VG30E is found so it can be measured up at the front.

mtcookson Posted February 2, 2008 Share Posted February 2, 2008 Ahh yeah, in that case the Z32 clutch and flywheel would definitely be the way to go. I believe most take some material off of the snout and a little off of the timing belt gear and crank pulley at the same time. They are case hardened so you have to be careful as taking off to much material will heavily weaken the parts from what I've heard. Quote Link to comment Share on other sites More sharing options...
260DET Posted February 2, 2008 Author Share Posted February 2, 2008 That taking a bit of metal off thing is the bit I'm not too keen on. Who knows, it may be possible to use Z32 parts at the front too. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted February 3, 2008 Share Posted February 3, 2008 I was wondering the same thing myself. I have a DE in the garage that I was going to take apart to see how close it was to the E but just haven't done it yet. I think I read somewhere that the VG33's crank snout is larger than the 30E so that could possibly be another option as far as matching things up.

Guest TeamNissan Posted February 3, 2008 Share Posted February 3, 2008 I read the same about the vg33. The snout on the vg30i is longer then the vg30e as well. I can attest to that personally as I just did a vg30e swap on my d21 that was a vg30i. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted February 3, 2008 Share Posted February 3, 2008 That's interesting. Is it longer than a W-series VG30E or was it non-W? Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted February 3, 2008 Share Posted February 3, 2008 I'm guessing non w as it was out of a 86 z31. I should have checked but I didn't learn of the change until after the fact. Motor sports auto states for the w series... "The crankshaft front tip was lengthened by 18.7 mm (0.736) in. The crankshaft pulley width was increased by 13.6 mm (0.535 in.)." If thats the case then the I is longer then the E but shorter then the W series E. I didn't realize how many changes there were in the 1st gen vgs, getting complicated lol. I probably would have been better off going with the w series in hind site because that snout difference caused some timing cover/harmonic balancer clearance issues that I had to resolve.

mtcookson Posted February 3, 2008 Share Posted February 3, 2008 Ahh, ok. Yeah it was probably just a W-series VG30i. The W-series change was in 4/87 (88 model year I believe) for the Z's, I'm sure the others were probably around the same. Quote Link to comment Share on other sites More sharing options...
