Is This Too Much Vapour / Smoke / Steam from Catch Can Filters?

I guess I can always change the housing if need be, but I'm pretty sure the 1.05 will do me for now.

Any recommendations on what I can do with the gearbox? I'm sure with my luck it will break pretty quickly at the new power level, if I keep it stock.

I was considering a 1-4 or 1-5 helical dog gear kit from PPG, however once you add on the billet mainshaft and billet sandwich plate it gets expensive really fast, especially considering I would have to pay GST again on top of that!

Does anyone know if the billet sandwich plate is really needed?

Another option I was looking at, which is more local to me, is this: https://www.trademe.co.nz/motors/car-parts-accessories/nissan/gearboxes/auction-1546714929.htm?rsqid=a95b22b0506842ddbe40b7846d38df8c

It's straight cut dog box 3rd/4th, with stock helical synchro 1st, 2nd and 5th
It would end up being cheaper than the PPG option, however it could be weird retaining synchro on 1st and 2nd?

Anyone got any ideas?

Sandwich plate is the key to box strength.  It cuts down on the flex in the housings that allow gears to change position relative to each other, etc etc blah blah yada yada.

So the PPG 1-4 with the billet mainshaft and billet sandwich plate will be a pretty bulletproof setup for up to 1000hp?

Depends on how big the bullet is.  But, I guess the answer is a qualified yes.
