When i bought my VL Turbo it had been converted from a auto to a manual. Instead of using the original turbo box, they used an RB20DET box from a R32 Skyline. That gearbox is now history and i have again had to put one of these boxes in (lack of money and availability of turbo box in Adelaide). Some people that i have talked to say that its a **** box and others say that its just as good if not better than the turbo box. Can someone help me out here and tell me how strong my box is? :?

They are complete pieces of ****, no offence intended, they are not designed for the power of a vlt and they are cheap and nasty like the motors they come off. A vlt five speed will set you back about $900, maybe start saving for one when this one goes. They are bloody strong and shift really nicely..

If you really wanna go hardcore, chuck a supra box in ..... prolly gunna have to do something like that myself after the intercooler is put in.

make sure u put in a supra turbo box not a n/a box the turbo box is more $$$ but alot stronger than the n/a, the n/a box is still good but not as good as a turbo one

Woah! Here in NZ, the Skyline R32 GTS-T (RB20DET motor) comes with a VERY strong manual box! The manual box outta the GTS (RB20DE) is ****e - blown a lot of those, but my workmates and I have a turbo gearbox (from a RB20DET) behind a 866hp engine, and its never had a problem or made any weird noises!

the VLT box is the 81 mm box fitted to late 300ZX. in nissan speek they were RS581A commonly used in navara/patrol etc but with 4.222 to 5.429 first gear ratios. the new number FS5R30A 3.325/4.061 FIRST GEARS OPTIONS. but i havent checked if the internal swap over to the old type. the big problem was that the vl used a long transmision.

DUZ THAT MEAN THAT WE CAN START USING NAVARA G/BOXES 4 A SUBSTITUTE 4 AS VLT BOX ??? A mate had a navara ute with an rb20 det in it ...went well .... it had a HUGE front mount cooler , hybrid T3/4 turbo , EMS computer & on 19 psi ..... HANG THE **** ON !!!! Anyhow , sorry to get offtrack , it used the standard navara box,tailshaft,&diff ...... he blew the box once though , as it was the original 300k box .... Some original photos have not been recovered yet.

I dont know but. a import rb20/25det box my guess would be cheeper.i sold a r31 rb20det box to a friend for a VLT calais out of a GTS-X.it got a hiding and had noisey front bearings [and still does].this had a braced casing but was the 71 mm box. but if you had a dead vl box then you could use 300ZX/navara/urvan/patrol,etc.as donnor parts. but if you experts out there can tell me,as i havent drag raced etc[only rallying].for my conversions i go for a wide ratio box and tall diff ratio. ie a normal VL has a 3.2 first,i use a 3.5/4.2 and a 3.45,3.36,3.08.in my last VK 3.36 and a 4.2 1st,0.9 od.this allowed slow travelling without the VL hop.the ratios are even spaced except top.this is as i do a lot of highway stuff with the shopping center crawl.i drive heeps a cars doing services and i dont understand the logic of using closest ratio in a road car. the original raios in the first release VL were 3.5 1st 0.75 od but these are rare [correct me??] for aust.
