Booztd 3 Posted June 7, 2008 Share Posted June 7, 2008 Alright guys, I told you an update was coming, so here it is! After going through 3/4 transmissions due to broken shift forks, bad syncrhos, etc, I decident that since most of my time in the car is spent on the drag strip, its probably best that I go the automatic route. After alot of talks with Brett Dempsey at BDE (Brett Dempsey Engineering) we decided a reverse manual vavle body TH400 was the way to go. Brett has developed a conversion kit for the VG30 and the RB26. The specs are as follow: Built TH400 BDE RB26 Conversion Kit JW Aluminum Transbrake w/Reverse Manual Valve Body TCI Deep Aluminum Pan Precision 5000 stall converter B&M Composite X Shifter Custom OEM 1-piece driveshaft B&M Supercooler TH400 Kit Now On to the install pics! Current Engine Bay Setup OEM Crossmember vs Modified OEM Crossmember Autometer Mechanical Trans Temp Guage mounted to the Roll Cage Composite X Shifter B&M Super Cooler TH400 kit from Jegs ARP 7MGTE Flywheel Bolts (same pattern as 300ZX/RB26) Here's the old 5spd, had a pretty decent grind in 4th.....getting ready to come out A good friend allowed me to use his garage which had a really nice lift and trans jack A closer look at the tranny & conversion. The bell housing is a modified RB26 automatic bell housing Here's the difference between the OEM flywheel bolts and the ARP bolts The OEM bolts stuck out too far, sine the flexplate is thinner than the flywheel This may be hard to tell, but the RB26 has a dowel pin for alignment of the flywheel. This had to be removed Trans on its way in Here you can see the precision converter The trans went in super easy. The crossmember is mounted to an OEM TH400 tranny mount Getting the 5spd stuff out of the way Shifter contents I made my own custom shifter mounting plate using some moderatly thin aluminum. I Just traced the bolt pattern of the 5spd brakect, and cut out, and drilled the bolt holes for this. I then had to drill a large hole in the tunnel for the shifter cable to pass through Shifter is in, and interior returned in to place A final look at the interior Here's the shifter cable routing I had to custom make the SS lines for the oil cooler I mounted the oil cooler in the passenger side fenderwell of the car Here's some pictures of the driveshaft. Its a Z1 1-piece driveshaft for a VG30 application, shortened 1-1/2" I also had to have a 1350 style u-joint installed (Z1 uses a 1310 style) and a 1350 yoke was installed as well. It cost around 100 bucks for the driveshaft shop to do. Heres the driveshaft engagement. It has a few inches of engagement onto the tail shaft. I have been driving the car around for a week now, and it absolutley RIPS! The car feels like a totally new animal, and since the car is manually shifted, its just as much fun to drive on the street as the 5spd was. I need to tweak the tune on the car, I think because of the heat, its getting to much fuel (its been adjusted for how cold it has been here lately) so I am getting a little sputter in high rpms because its so rich (10.0 or worse!) The car is entirely streetable still, even with the 5k stall, the car starts to creep forwards when I let off the brake pedal, and its moving at around 1500rpms. I am really hoping for some low-mid 10's on pump gas with this setup Thanks for looking! Quote Link to comment Share on other sites More sharing options...
cockerstar Posted June 8, 2008 Share Posted June 8, 2008 Love it, love it, love it! I can only imagine how much easier access to that garage made everything. When are you going to be able to get some runs in at the track? Quote Link to comment Share on other sites More sharing options...
stony Posted June 8, 2008 Share Posted June 8, 2008 How fast does boost come on??? Quote Link to comment Share on other sites More sharing options...
Booztd 3 Posted June 8, 2008 Author Share Posted June 8, 2008 How fast does boost come on??? Really not much sooner than the 5spd, maybe a little sooner........considering the stall is at 5k, it doesnt really start to load the motor until that point. I know at WOT shifts im going back down to 6200-6300rpm which is perfect considering on the dyno it appeared my powerband was from 6-8k......

Northstarninja Posted June 8, 2008 Share Posted June 8, 2008 Sick... I may have to steal this idea for my Z. I'm debating whether or not i should switch the Z to a live axle using a ford 9" rear... Quote Link to comment Share on other sites More sharing options...
Booztd 3 Posted June 8, 2008 Author Share Posted June 8, 2008 I have seen STOCK Z32 rear suspensions support 1.2-1.3 60ft times at the drag strip........the whole rear end assembly is built incredibly well....i dont see any reason to switch to a ford 9" (assuming you have a Z32, i dont see any info) Quote Link to comment Share on other sites More sharing options...
mannyvig Posted June 9, 2008 Share Posted June 9, 2008 Well I hope our old auto rb20 bell housing helped out. I never thought that would leave the garage. Just one more impressive thing you have done on this build. Keep them coming. Quote Link to comment Share on other sites More sharing options...

You will need an adapter kit. I purchased the RB20 bell housing and sent it to the company developing the kits. They modified the bell housing and shipped it to me, along with the rest of the parts.

RIPSNZ Posted June 11, 2008 Share Posted June 11, 2008 I have RB30 with T400 and 5000 stall and I agree, its great on the street, you'll do much better at the strip I'm sure, did you put a transbrake in it? if so, get some NOS on there Rob Quote Link to comment Share on other sites More sharing options...

To answer your question, Yes, I have a JW aluminum pro-transbrake installed I hope to get to test the nitrous today Quote Link to comment Share on other sites More sharing options...
