Default Use my K20a for turbo project? Or get a cheap K24?

Hey everyone. I've been out of the honda game for like 8 years, and I need some advice. I'm importing a CL7 Accord Euro R to Canada (theyre really cheap at auction right now in Japan, going for like $2000-4000).

I'd like to do a turbo project with it (maybe 350-400hp, nothing insane). I've done a K-swap before, so I'm pretty familiar with the engines. What are the general thoughts on using a Type R K20A motor for forced induction? The high compression ratio worries me.

I could sell the K20A, and build a decent Accord/CRV K24, but I'm not going to go through with that unless using the K20A is unadvisable for some reason.

I don't see many K20A turbo projects, but its probably because its generally a waste of money.

Keep the stock compression. (the days of Low CR=better for turbo are LONG GONE) turbo k-series aren't a waste of money. in fact, the engine is robust enough to take that power on its own block, without the need of a full build.

Just keep the turbo on the smaller side of 48lbs/min-55lbs/min. don't get cheap using CXRacing **** and you'll have a fun street torque monster that will bring comfort and many smiles to the face.

Gotcha, I'll keep the K20A motor then.

And what I meant about being "a waste of money" wasn't K-series in general, I was wondering if turbocharging a Type-R K20A (as opposed to a cheaper K-series) was a waste of money.

Like Shodan said, static compression doesn't really matter as much as it used to because of tuning advances. As long as your tuner is competent with the software used, you should be fine.

Hell my last 5-6 turbo setups have all been 11:1-12:1 static compression. Not a single issue.
