Hey Guys and Gals,

Have just started the "turbo" part of my K20/EG Hybrid build. There are no other Turbo K20 setups here in New Zealand so I am after some knowledge from those who have done it before to see what "trick"s there are to look out for and if there are any "HAVE TOOS".

here is a quick run down on the setup.

JDM K20 ITR running gear
Innovative Engine Mount Kit
Karcepts Pulley Kit
RBC Intake Manifold
70mm BDL T/B
GT35R .82 exhaust
Tial 44mm wastegate
Tial 50mm BOV
RC 750cc Injectors

Any info at all with respect to things to look out for would be great - a couple things specifically that I am unsure about is the breather system - the stock system just has 1 breather by the power steering pump and one on the rocker cover...certainly isn't going to be enough. Obviously more out of the rocker cover is a given but do people also enlarge the breather for the block and run a big line from there too?

also intercoolers - a lot of guys run a in/out setup on the same side of the intercooler - is this is purely for easy of piping etc?

What kind of power/boost do the stock motors reliably handle? I plan to run my low boost setting as low as I can get the boost to hold - hoping for around 5 or 6psi and then have some boost settings on the K-pro from there to around 10 psi.....

also - the plan is go to a k24 bottom end later on - with the same turbo setup - is a 4 inch exhaust ideal or is 3" fine? it is a street car.

what kind of power is the stock clutch good for?

ANY info at all you guys can help with would be great.

here is a pic of engine bay - not a great one.

if you have a look around on that image hosting sit there are heaps of pics of the car inside and out in its current form.

 

anyone?

 

That u know of

 

Love to know if there is another one - get some tips.

Someone here on HT must have a few tips for me.

 

there is one built in the south island.

There is/was one turbo'd K20A RHD EG hatch on K20A.org too i believe

 

yeah - hoping to get some better results on there- seems there are no K20 turbo owners on honda-tec willing to share knowledge.

 

3" exhaust is plenty, 10psi should be fine on stock k-series, i myself wouldnt go any further than that but ive seen ppl push big power through stock K mtrs... they are known to take a beeting. its just the matter of (how l0ng will it last) the stock clutch should hold somewhere near 300hp maby abit more or a bit less .. GL!!

 

with that turbo I think the RC 750's will maxout before full power is reached. Maybe the Injector Dynamics 1000's would be a better choice for you. Oh, just noticed you only want low power levels, 750's should be ok for that

 

thanks for the replies - I would have expected that 750's would be good for around 450-500WHP? which is probably as much as the car is ever likely to see unless I wanna drop big bucks on a forged motor.

 

stock clutch wont last too long on that setup.
