Hey,

I am wanting to get some information about the Lenco 3 speed gearbox.

I'm struggling to find info about an adapter plate / bellhousing to suit an RB30 block. I also cannot find the power ratings for the box and would like to know if anyone can help me with this.

thanks

Is this an all out racing transmission? From what i know about lencos (and a quick searcg i did this seems to be the case)

Probably will be a custom bell housing/adapter ring, i would serioustly doubt that there would be something off the shelf, expecially as the RB is not so popular in the usa compared to its toyota counterpart for drag racing.

6 second passes good enough? if its the same box it will take anything.

Lenco's are not automatic transmissions.

*EDIT* Unless you are using a Lencodrive transmission which runs a torque converter (even then it's not an auto) but I'm guessing your RB30 isn't powering a 3500hp Pro-Modified car :P

Who put you onto this lenco idea?? Its stupid crazy overkill for a rb30!!! Esentially a 3 speed lenco is 3 gearboxes and is essentially an assisted shift manual. Even if you are running lets be ridiculous and say 1500hp out of a rb30, a dudenbear built or Al's or other top name brand from the states can build a th400 to handle that as its torque that kills the box and a 3 litre doesnt have as much torque as a 1500 8.6l chev, and they can make them to run on 1200hp chevelles etc!! Its a cheaper option, CMRS make adapters to suit rb series engines and parts for them are readily available.

Instead of about $20000 you would be looking at around 6g!!

20k?

I've seen complete rebuilt lenco 5 speeds with twin plate clutch, trans. blanket and bellhousing sell for $5,500 US.

I am definately NOT going for a powerglide option.

I am looking at a turbo 400 box too but just weighing my options up at the moment.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2

      Yes it is ATF. I quote @Duncan "it takes a good synthentic auto trans fluid like Castrol Transmax Z" It's not a diff. It's a transfer case. Totally different thing. Yes, fluid will come out the sender hole. No you do not really need to drain it. Just pull the old, quickly poke the new, clean up and top up. But realistically, you should probably take the opportunity to change it anyway.
