Opinions needed: Crazyv's Prepping the B20Z for 250whp turbocharged power
So I'm playing around with the idea of boosting my 2001 CR-V w/ 5-Spd AWD, its got a bone stock B20z with 220,000 km (137,000 miles) on it
My goal is about 250 hp, maybe up to 300 if feasible, but I want to play it safe considering its a B20, I'm not racing anyways it's a daily driver.
My idea is to build up the lower end a bit given its mileage, for a turbo kit I'm seriously considering this cxracing kit, I know its taboo and risky, but its
a more or less complete kit, and from what I've read, they seem to work fine for low boost, and this one wont ever see more than 10 psi. though I'll
probably change out the bov and wastegate for something better quality. T04E at <10 psi should be fine for a b20, right? I'm a noob at this for sure.
What I have in mind here is:
-New pistons, probably nippon turbo or anything thats strong and doesnt affect compression much, maybe rods too
-New bearings, oil pump, headgasket, general engine rebuilding
-ARP head and rod bolts
-2.5" catback exhaust
-Stage 3 clutch
-91 octane gas, walbro fuel pump + bigger injectors
-Maybe a p8r head if I find one, or would it make no difference for my power goal?
-Maybe a new intake header, like a B16 or LS, if the stock box resonator would interfere with boost
For tuning I guess I'll just see what my local tuner likes to use, but from what I gather I'll need to convert to obd1? No obd2 tuning?
Anything else I could need or should have? Or am I overdoing it for what I'm trying to go for? Will weather be a concern? It gets both real hot and cold here (-30 C in winter, up to 30 C in summer)
Assume that I'm sticking with stock sleeves, since sleeving my block is gonna cost a lot, given I'm in canada so I'd have to ship it to the states or find some local shop that can do it,
and I'm not sure if its worth it for what I'm trying to do. I was thinking about swapping in an LS motor, since those are surprisingly cheap to come by, but I kind of want to keep the 2L displacement.

If this isnt your only driver, id boost it completely stock under 250whp if that. Then see how long it last, what fails etc. Then go from there. If anything you could do arp rod bolts and arp headstuds.

Make sure you have a back up car available before you start boosting your daily.
250WHP on a healthy B20z with a good tune should have a pretty decent amount of longevity.
