Do any of you love birds have any experience with machining costs ?

I know you do.

I am rebuilding my 26 and am looking for a very rough estimate on the costs of crank preparation (if indeed mine is still in good condition).

The reason I ask is that if the costs to prep and ready the crank for reuse are substantial I will just buy a 2.8/9 stroker kit as it's the crank that adds cost to these kits.

Just as an offside, I will be using this turbo so will welcome the extra cubes:

Generally a crank needs

  • Plugs drilled out, tapped, cleaned and grub screws inserted
  • Clean in hot bathCheck for straightness.
  • Check for clearances to block and girdle
  • Check for clearances to rod big ends
  • Linish lightly or for oversize bearings
  • Fit Crank collar if it is 32 or early 33 crank.

A rough guide is $500-$1000, towards the higher end if a bearing was spun on the old motor.

Cheers guys,

I am leaning towards a stroker because the price I saw for a new crank is about 1500 from JJ and Ebay etc.

another 1500 can get me a 2.8/2.9 crank in a kit for about 5000.

Unless any of you know a better place to look/have a better idea.

And a brand new crank is only $1100 or something from Nissan.

A lot of people just buy a new one for this reason.

And after a day at a machine shop for an open day, I'd be sending a brand new crank to be check up on anyway...

totally agree. I've had tolerance issues with brand new nissan cranks and a brand new n1 block. always get it measured before you use it

Thanks for responses.

What do you guys think of these bad boys ?

Do I really need a stroker ?

One thing to think about is the weight of the cranks etc.

From memory the BC crank weighs a bit more than the HKS one as an example. So depends what you want characteristics wise and use of the car to boot.

    • These are small points I should actually add to my original post. GKtech makes an extended slave line for this conversion. It's what I use, and it works well. You'll also need a CD009 slave cylinder.  S/R Chassis Z33/Z34 Conversion braided clutch line As for transmission sensors, you'll need to both extend the wiring and replace the connectors. I can't recall which is which, but one is your neutral switch and the other the reverse switch. As they are just switches, just test for continuity with your transmission in neutral or reverse to figure out which is which. Connectors:  VQ35 neutral Switch Connector | Wiring Specialties VQ35 Reverse Switch Connector | Wiring Specialties 
    • I’ll try and see it could be the release bearing. As for the 4th gear grind maybe clutch doesn’t disengage properly cause it is slightly like very slightly hard to go into first could be due to the slab cylinder pin being short uni clutch is a twin plate.   Ive attached some assembly photos hopefully you can open the link and see maybe detect what’s wrong https://share.icloud.com/photos/0dc2YvW__Hl6jl-l2_0jejjpg https://share.icloud.com/photos/09e0jkWOK-vP48c1cfY6u3ViA https://share.icloud.com/photos/0b4rDmh5R7pK7fb1VtND73a3g https://share.icloud.com/photos/05eeUi_6dC4DVi80jOUYDgb0g https://share.icloud.com/photos/06335TgY1XxyIJal_wkdQLhzw
    • Yeah for sure that is peddle adjustment 
    • What are your thoughts on this after having it for a while, worth getting?
    • Downshifts are harder on transmissions than upshifts, the input shaft naturally slows down once disconnected from the engine so the synchros aren't doing all the work. There's no "natural" tendency for an input shaft to increase RPM. Something is not right there, I don't have a great answer on what. You can try a dedicated GL4 75W90, I plan to switch to Motorcraft XT-M5-QS which is supposedly a very good 75W90 for NB Miatas which have a weirdly sensitive transmission from the factory. I would chase down why your clutch is making a hissing noise, that's not normal. It might be no big deal but in the absence of anything else to investigate I would look at that.
