    Lots of factors there and depends on what compression ratio you are looking for and how much boost, 450whp is almost 500 crank hp , will be overkill on a street car setup almost

    I was thinking about 12 to 16 pounds of boost and with stock compression or would it be more reliable to run lower compression???

    i good turbo street car IMO is around 9.5 CR. You'll make more power at 10, but you'll have better off-boost response than 9 and have some leeway for tuning error.

    Tuning is key.
    you'll need some large injectors (750-1000 cc) and something better than a 'generic' chipped ecu if you don't want this thing to blow up.

    I would advise something better than eagle rods if you're really looking to hit 500.

    I say pick up a healthy b18b for less than rebuild cost and run a small 7-9psi with a good tune and have a reliable 300-330hp

    Matt and I both used Eagle rods I believe. I'm running 9:1comp forged pistons but I'm staying non vtec so I'm just gonna feed my motor 20lbs of boost which will raise my effective compression significantly, making the lowered compression a good idea. Honestly for 400 I would copy Matt's build and use a slightly smaller turbo just so it spools faster since the extra power is mostly unnecessary without doing a lot of work to put it to the ground efficiently, otherwise it'll be a lot of one-wheel-peel.
