Gen2 Hayabusa Motor Build for Stage 1 (rcc)Turbo Kit

[sbarna992]

Family,

I'm about to purchase a stage 1 RCC (kit with BOV and water/meth injection and HD clutch springs). Before that I am going to be having my motor out for a transmission (shift fork) issue so I figured now would be a good time to beef up the motor for turbo applications. This is what I'm planning:

1. Cylinder Studs
2. Heavy Duty Valve Springs
3. Stainless Steel valves
4. Turbo Pistons
5. Turbo rods

I am planning to run maximum 8 psi of boost.

My question(s) are:

1. With the above setup will I need to install a base spacer as well?
2. With the above setup what would be the potential maximum boost I could run?
3. Do turbo pistons lower compression making a base spacer unnecessary?
4. Are there any additional changes I should be doing?


Cheers!

No you don't need the base spacer. And as far as boost it should take all that the turbo has to offer. 550+ HP, well that's with the right fueling upgrads too.

Gen2 turbo pistons lower compression won’t need a spacer.

Like @01smokes said you do those upgrades motor should do everything that turbo can.

You missed head studs

Did you see the #1 thing on his list?

Cylinder and head studs are different

Cylinder and head studs are different

What is the difference?

What is the difference?

Hi There are 3 stud sets. 1 holds the head cylinders to the upper case half. 2nd holds the crankshaft and the lower case half to the upper case. the 3rd that one holds the out put shaft and the lower lower case to the upper case half

ah gotcha. thanks for the info!

Just bought a RCC Stage 1 kit off Richard today (amongst a long list of other parts) and also Wossner 9:1 pistons and rods; he said no base spacer is needed for my '18 model with turbo pistons - however the rest of the engine is getting Cometic gaskets as it goes back together. I've been asking him lots of questions and I sure will be asking some here, but don't want to be that annoying kid who constantly asks "why"!
I'm going to throw a EGT Pyrometer up its kazoot during dyno tuning out of interest to see what the EGT's are under boost. Wossner safe temp range 1300-1500 F (700-815 C)- that's aircraft grade!!!

Don't need a spacer if you go with turbo pistons on any build turbo build.

Ask away that's what people here for, I was calling companies and messaging peoples ears off. Don't be shy it's your money down the drain if it goes bad. I'd probably start a thread though keep it all in one place.

Sounds like you got a good setup planned. Don't forget the cylinder head is still aluminum. It can melt possibly quicker than the pistons.

max of 8 PSI rods are not needed
you should be under 300 ish HP at 8PSI
If you have the coin better but unless you are leaning on it harder than that
