Guys you can get a ford 9 inch irs diff. And i will need 5.8 and 6.1 gears becouse i am runnig a bert gear box so i will be runnig in top gear not 2nd or 3rd it is alot cheaper in speedway to go bert gear box then buy a really good light fly wheel and clutch and then keep replaceing gear boxs as you blow them

one of the nissan vans runs an r200 with a high ratio (serena? espace?), there was a thread recently. It was about 4.9 I think.

Or maybe a custom pinion gear with the right ratio?

r200 is a very strong diff, and if you did actually have trouble with it (unlikely on dirt) there is always r220 out of 300zx that would fit.

Of course you can put a 9" in it, anything can be done with enough time and money, and sometimes it's worth it for reliability in a specific purpose.....not sure if there would be many IRS speedway cars out there?

How much power? Have you considered a hq 3 speed box? top gear is 1:1, they are cheap, lots of guys at home put them on the back of 350chevs in saloons in nz.

We ran a 6.5 9inch then went to a 7!!! it was like a worm gear!

Plus you can get the 9 inch head with an alloy nose and carrier to save a bit of weight.

      Shifting questions

      By DRoc81 · Posted

      This was a huge help.  We followed the steps,  although shifting into 2nd was actually into 3rd for us,  and 1st was into 2nd ( steps 9 and 11) .  The long flash was the 4th flash.  So shift solenoid A is possibly the culprit.  Is this inside the transmission itself? Or is it accessible by just front the pan? Or is it bolted to the outside of the transmission?  Thanos for your help everyone

      Can you enlighten me on your best practice regarding these hoses? I don't wanna make the same mistake if you already got a better solution.

      I have some silicon hoses already, for example engine to watercooler. But yeah, I get the sentiment. The lower intercooler silicon hose is drippy too, despite not being very old. Does anyone except Nismo make these same lines out of rubber? Long term I think they'd be the better replacement, especially since the car won't live as hard a life anymore as in the past nor be driven as often.

      I know most issues are just age related. But for example the turbo oil drains, there is dash adapters for these and you can just make a braided teflon line for them and (probably) never have them leak again. Also not terribly expensive. Can you even get the factory hardlines from new? Or are they repairable if they break?

      I know it'd be much much easier with the tool. I hope I can find one that won't take 3 weeks to get to me an isn't a "Asian models kit" that has tons of (to me) useless adapters for a load of cash.   It's a summer project/fun car. I do wanna enjoy it, without endless downtime over and over. So yeah I would even go and buy an engine crane + stand to save myself the trouble of hard to reach or unreachable places going bad later on. Would also be a good opportunity to put on a Fluidamper, renew the mains seals and stuff like that. I have some money on the side that I can use for that, what I wouldn't want to or be able to do is let everything be done by a shop or have my engine completely rebuild right now. I intend to do most of the "doable" jobs myself. Pulling an engine can't be that hard, can it?
