I'm 100% sure my 3rd / 4th gear circlip has let go. There is talk some people weld the gear in place vs regrooving and fitting a larger circlip. Has anyone had experience with either method?
Thanks for the feedback, I recognised your comments on the nissansilvia.com site. I'm trying to locate somewhere in Auckland that has done the circlip mod. I'm hoping someonw knows what to do as the exact technique is not clear to me. Some people refer to making a newly located deeper groove, however I assumed you'd just make the existing groove deeper and fit a tighter circlip - could you confirm? My car makes 210rwkw, I haven't gone to a GTRS turbo etc partly because I didn't want to kill the gearbox and have to upgrade my clutch etc. I'm going to keep the power where it is so a conversion is probably overkill for me. That and I'm pretty sympathetic towards my gearbox, so I'm pretty surprised mine gave way (only 70k's on the clock too). Because of the low k's and known history, I'll definitely fix mine - it's just a matter of whether I try this circlip mod.I've done it long ago but there were too many risks, I never ended up using the built 6spd gearbox as it's only a matter of WHEN, not IF, it'll break. I ended up going with a gearbox conversion......... with me ending up on my 3rd gearbox conversion. Do it once and do it right.
I don't get this.. how does it cost $1000 to break your own gearbox? I thought that was the free bit! If I break a box I see it costing £450 for a box and £50 to borrow a ramp and a mate to help do the work. Plus the best part of a day to change it.So you broke a gearbox, $1000
Pick up another gearbox, $1000
Labour to swap them around, $400
Downtime, depends how quick you find a replacement gearbox
Free? So when can I come around to pick up that perfectly working gearbox for free? Or would you want 450gbp for it?I don't get this.. how does it cost $1000 to break your own gearbox? I thought that was the free bit! If I break a box I see it costing £450 for a box ...
I do drift Although I'm sh!t at it, and I also circuit race and daily it too hehe I go by the "prevention is better than cure" mantra, so now that it's upgraded I was going to install my GT-RS, but actually had to sell it to fix my motor. At work we're developing new turbos for SR20, so I'll get to test them out without fear of breaking the drivetrain.Thanks again Wing. You're running a pretty serious driveline for a stock turbo car - drift action I'm guessing? I was hoping stock turbo and clutch would lead to gearbox longevity - but I guess not. I just put in some magic Amsoil gearbox fluid too about 2 months ago so that'll go to waste.
I was quoted today $1800 NZD for the circlip mod. I'm still shopping but expected it to be around that. Unlike some, I have no noises from the gearbox so I'm hoping internal damage is minimal and the bill may be lighter.
I want to keep the original gearbox in play so I think I'll be going for option 1 - wish me luck! I'll let you guys know how it goes.
Ok.. My gearbox blows so I spend £450 on a new box and am I'm the same position as before. Hence the cost is £450, not £900. there are different ways of looking at it I suppose.Free? So when can I come around to pick up that perfectly working gearbox for free? Or would you want 450gbp for it?
