R32 Manual Conversion.

[skyline32sup]

So I'm considering trading up my S13 NA for a R32 NA, The thing is it's auto...

I'm had a 5 min look through the forums and couldn't really find what I'm after so here it goes;

Costage round abouts?

What's involved?

Would you stick a Rb20 gear box or 25 in?

Thanks, no trolls either don't really know anything about drivetrain.

Wouldn't recommend an RB25DET box for an RB20 NA, too big, heavy and strong for the almost zero torque levels that you can throw at it. Too expensive too. An RB25DE box is essentially the same thing as an RB20DET box, just slightly different ratios. Either would be fine. Either should only be about $500.

You will also need a flywheel. If you get one with the box, so much the better. Otherwise they are cheap enough secondhand, but you could also buy a brand new lighter one for a few hundred.

Clutch - doesn't need to be much. A standard one will do the job. Cheap enough.

Gearbox crossmember and mount needed.

I think you need a different front half of tailshaft.

You will need the pedal box so you can hang the clutch pedal. You'll obviously also need the clutch master, clutch slave and some pipework. This stuff is best gotten from a wreck unless you want to make the lines up new. Make sure that you get the right slave to suit the gearbox that you buy. There are differences.

You also should get the driver's side engine bay loom from a manual. Will make it much easier to put it all together than trying to mod the auto loom.

But, I must say, that all this adds up to far more $$ than I would ever recommend that anyone spend on an NA R32. Seems like a massive waste of cash, when you can buy a manual turbo R32 for somewhat less than $10k most days of the week. Even if you do it with a turbo gearbox with the later idea of putting a turbo engine in, you need to throw so much more money at it (brakes, hubs, diff, fuel pump, intercooler and pipework, etc etc etc) that you would have been far better off just buying a turbo in the first place. I know you're not asking about turboing anything, but it's a logical path to want to follow (just not logical to do).

Even though its a gtr box, prices are close to the same

Okay, You gave me all the info i needed, thank you kindly. I really don't want an auto car that's all.

So basically, in the end, Unless it's my pride and joy, It's not worth converting? I think i'll give it a miss then but will find out prices, once again thanks.

Exactly.
