Would a VL Turbo box be as strong as a RB25DET box ?

the VL box is not.

it has a rougher shift and less syncjro's or something to that description.

coming from the VL "area" of the world, i've seen many a blown manual MX-7

the RB25 is MUCH tougher

the vl n/a box is similar the rb20 box

the vl turbo box is similar to the rb25 box

from what i've seen the only major differances are that the rb20 and rb25 boxes have double synchros on some gears whereas both vl boxes are all single synchro.

plenty of poeple have put lots of power through a vl turbo box without a problem, and the only way i've heard of them breaking is when boosting hard with a modified motor in 5th gear.

i doubt the RB25 box is 'MUCH' tougher, but i'd get one of those if i could purely because its newer and with the double synchros it should be a smoother box.

The R33 box has double synchros in the first/second gears.

The tolarances in the box are alot tighter than in the MX7 box.

Why dont we use the VLT box in our cars instead of the double priced rb25det box ?

the MX-7 is the Turbo box, you wont find them cheap.

The "half priced" one is a stock N/A box, which is still over priced for box only.

The R33 G/boxes are the toughest. No denying that at all as can be seen from the majority of posts.

like i said, i've seen MX-7's blown, but nowhere near as many RB25 boxes.

Could be due to a lot of things, age being one.

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      Ticking Sound On Idle - Rb25

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?

      Sorry for reviving an old post, but I'm having the same hot idle tick issue. Did anyone ever find out what it was?  I have checked/ replaced Injectors Coils checked Lifter clerance (is at zero) Checked Cam lobes Replaced exhaust gasket and studs Would appreciate any advice this is driving me nuts

      There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)

      What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
