How do you accelerate without using the throttle... unless rolling down a hill? ?

Can’t see how it couldn’t if you get pistons for a RB25. 71.7 mm stroke 121.5mm rod RB25 piston its the same geometry as a factory RB25. if you got a piston for a RB26 or a HKS 2.8 it wouldn’t be right. You can use any length of rod, crank and piston pin height you want, just need to make it up or lose it in another area. At the end of the day you have the same length rods as a factory RB25 even though they’re out of a 2.8 kit. Just so happens that it all works. Have you considered sourcing a stock RB26 (73.7mm) crank and pistons? If you’re buying pistons anyway, get a crank for a cheap stroker kit.

That’s a seperate issue all together. Wherr the pin sits in the piston itself. If the RB25, RB26 and some RB28 kits use the same 121.5 mm rod but have different stroke lengths then the difference must be where the pin sits in the piston considering they all go in the same height block.

All depends on pin height.

PPG do one for the 5 speed.

Wouldn’t be so bad if it was only just the turbine housing. Need the manifold to suit.

Incorrect. RB25, RB26 and the HKS 2.8 use 121.5 mm rods. From memory the RB25 NEO ran RB26 rods from the factory. HKS get away with using a factory length rod while using the 77.7 mm crank by moving the pin in the piston.

Be waiting a while. Maybe the new HKS journal bearing nuggets. ??

Forget the 0.92, go the 1.05. Below is a back to back on a 2.7. Blue is 8374/1.05 and red is -5’s. Only change was associated pipework to make the single work.

Jap is always best in some eyes. ??‍♂️

Having done this exact conversion myself, 8374/1.05 all day. A dyno sheet only shows show much, actually, throw the bloody thing in the bin. 8374 to -5’s is much more than 300 rpm difference, more like 500-700 rpm not to mention the zing under the foot once you put the twin butt plugs in the dumpster where they belong. Transient response difference between the two setups are night and day... ALMOST 1/3rd the time, the winner going to the 8374. This was shown by logs off a mates car who also went between these two exact setups on a 3.0. Thats something that is not shown on a dyno sheet with a WOT loaded run. Having also been in two different cars (2.6/baby vcam/-5’s and 2.6/baby vcam/8374), the 8374 would destroy it EVERYWHERE.

Any idea if he has done an 8474 yet?

Turbo selection cost is a drop in the ocean compared to setting up the rest of the car...

Why a 9174 when the 8474 is around? ?

Have you sorted out your exhaust issue yet?

Whatever a reasonable limit is for a stock SR20 bottom end. Don’t forget the gearbox is made from glass so that’s a grenade waiting to explode. All in it should do somewhere between 400 and 420 kw on E85, on a roller dyno.

Turn the one on the comp cover up as high as you can. That should do the trick. ?

BK, it’s on E85.
