L14 Rods WTD

I have a solution. Power without revs and adjustable from daily drivable to track beast. Don't fight it, its natural.

Hi Gav,

I'm currently going through this process myself & found that the best combo is L14 rods & L28 crank. I don't think you can use the L14's with the LD28, the throw is too long for this rod & I dont beleive you can get a piston with the correct pin height to match this set up. If you could get pistons with the correct pin height they would have to be custom forged & you'll be looking at $1500 PLUS...

If you're set in using the LD28 crank, you'll have to go for the L6 L20A rods & get a set of VG30E or VG30ET pistons (these are available in aftermarket forged design). Again, I don't see the need for forgies as the genuine Nissan pistons are very reliable, after all, the turbo piston is only cast & the VG30ET engine had 155KW on 6psi boost & they can handle double that no worries.

The 2 engines I'm building at the moment are both with L14 rods & L28 cranks, but in one I'm using VG30ET pistons & the other with SR20DETpistons. These both have a slight dish so comp will be around 9.5 & 10:1 with the closed chamber E88 head.

If I wanted 11:1 then I'd go with the VG30E flat top.

Just something to consider Gav.

P.S. L14 rods are very rare & expensive here in Australia (try $600 +), but you have a better chance in the UK.

Oh, btw, there are 2 types of L20A rods, one set is compatible to the L24/L26/L28 crank, these are actually 135mm long & the others have a much smaller jounal & stem, I wouldn't recommend these. ( These might be the 128mm type that Alan is refering to).
