Is there a dyno or some other information about how much this car gets better after install?

This is one wicked car!

This is the bit I'm curious about. Can you give some details on what exactly you have done to help with oil pressures?

Thanks!

@GT86_PRAGUE compare to stock , it added 220 hp and 154 Ftlbs of torque at the wheels

On a dynapack here in Japan, a BRZ / SCion Frs / FT86 , stock, generally reads average 145whp, mine is over 366 now ... I know some will just laugh at the numbers, but dynapacks read low, and we don't use correction factors. What is important is to see the power has been more than doubled over stock, and there is a lot of meat left on the bone, but we made the decision not to fry the transmission too fast. Plus, trust me it is already an animal.

So all in all we are above 500hp cranck.



@BatStig first the assembly has been changed for a fresh new one ! full timing timing chain cover integrating the pump, second, you can tweak the gearing of the pump and beef it it up a little bit, and there is some more know how, but that's more of the sorcerers secret.

Thanks. I didnt mention I was wondering more about gains without supercharger. Any idea?

[HaDDeS]

The stroker kit, HKS one at least is really aimed towards a supercharged engine, on a N/A setup, gaisn will be marginal, there will be gains, but not more than 25-30hp with the help o the Vcams

For a N/A setup, the toda 2.3 stroker is a far better proposal

[troek]

HKS shows the stroker kit and cams only gaining around 10 hp NA. I would assume that is untuned.
Also, awesome build, im very jealous, if your ever down in the tokyo area, i want a ride!

[ChrisD]

Such a well done build, and it looks so nice too!

I've currently got a stage 3 AVO turbo on mine and looking to get a bit more out of it so I'm looking at engine internals now. Someone recommended the HKS 2.1 stroker kit, and it seems like you're pretty happy with it. One thing I'm curious about is the new oil pump and pressure you mentioned. Any more details on that?

Oh and a tuner I spoke to said they haven't seen a need for new valve springs on these cars even at higher power figures but I thought I'd seen a few people on here mention valve float being a problem after boosting these things. Did you replace your valve springs or not?

[blindfold]

would you mind sharing where did you install your hks oil cooler? I am in process of installing everything and it seems behind the foglight is not an idea location for air to travel pass through the core, thank you.

You build very nice car. I am using the HKS V3 kit in China, 110mm pulley.
now my full boost almost 0.85 BAR 12psi so I just worry about my engine and what you said about the "tendency" bend.
could you give me a recommend for my car do I need install hks 2.1 now?
