Hi guys,

I am starting a somewhat unusual project in Brazil, so I am here to share with you and also to ask for help.
In Brazil we have very few units of the CRX 88-91, because it was neither manufactured nor marketed here. (all are of direct imports)
As my CRX is badly damaged, his D15 engine is no longer working and so I am doing a swap for the K20.
Here in Brazil, we don't have many K20 units either, but I got a K20A7 from the Honda Accord 2006. I know this is not the best version, but I got it for a very good price.
I need your help to find out if I can use the K20Z3 head in the future and what adaptations would be necessary?
Another thing, which intake manifold (low cost) can you indicate? Would the original K20z3 intake manifold be a good alternative?
And lastly, how much horse power can I achieve with a "basic" turbo kit? I'm thinking of running with 9 psi, with the stock engine.

Hi guys

I have a question about the same subject. I'm also from Brazil and I have an accord 2.0 with a k20a7 engine.

My cylinder head had a problem with lubrication and cam caps towers #3 #4 and #5 were damaged. I would like to know if the cam caps tower of the k20z3 cylinder head is compatible with the k20a7 head

The engine you have will support 350 whp and hold together fine with a good tune. You can make more if you want to push it , there’s members on here with that same engine block and cylinder head combo at 400whp. I would look into top mount turbo manifolds for ease of piping fabrication, but the sidewinder is the traditional route which places the turbo over the transmission next to the cylinder head.
