A d15b won't support anywhere near your power levels

And 300hp on stock internals on a b16 is seriously pushing the limit

Since you obviously have no idea what you're doing I suggest you read the faq and take your car to a reputable shop and let them do the work properly with quality parts

Those motors arent even a comparrison ,,b16 allday,, 300hp on a stock b series is ok with proper tune n supporting mods. Been done a million times. He said 250-300 ,a b16 will do that all day

Someone with lots of experience and using all quality parts with a rock solid tune, maybe...

Totally green to turbos? Doubtful. Start off low and work your way up

300 on e85 is 100% safe. we have a few running around at the 400hp mark.

I doubt this dude even knows what e85 is lol

And 90% of the country doesn't have reasonable access to e85, I know Georgia doesn't

I know the stock won't go for 350whp bone head..
I just need to know which TURBO motor will be worth to spent on upgrade..

But I search so much most of them said that d series turbo can get easily 300whp with a good turbo kits..so what upgrade do I need for the b16?? Thanks guys..

ChromeHeart

Thanks alot for the info

For the b16 to be a 100% reliable daily driver I would strongly suggest a built bottom end (forged rods and pistons, compression in the 10:1 range) for an added degree of safety. You can do 300 on stock internals BUT beating on it a lot/driving with spirit will stress the stock bottom end to potential failure

Also arp or golden eagle head studs and an oem headgasket. You'll nees a fuel pump say a walbro 255 at minimum and bigger injectors as well as a way to tune the car, also 2 step colder plugs

You'll also need an upgraded clutch mandatory

And maybe a few bolt ons to help like a skunk2 intake manifold, larger throttle body, etc

Really guys a b16 will do 300 all day long on pump gas so long as its properly tuned. 300 on an LS all day long on pump gas LOL and the b16 is stronger. You can make more than 300 on stock vtec bottom ends. With ethanol you can push 450-500hp. yes they wont last a long time at that power level but they will do it. Reliably 400hp on ethanol no problem.

That being said OP you have a lot to learn, read read read before you buy anything and def go with a b16 over the d series.

Yea I waa just suggesting he do it as a precaution. If he's buyinh a used longblock from some random importer/supplier you have no real way of knowing how the motor was previously treated and maintained. Nor what condition the internals are in.. I'm always weary of any engine supplier/importer

Hell he could crank it up the first time only to find it has rod knock or he boosts it and it lets go while tuning

I always say to rebuild any used motor you buy with the intention of boosting for these very reasons

I can't tell you how many complete sr swaps we ordered at the shop only to have them be total piles of **** when we unpacked the pallet

that sucks every crate imported motor ive delt with has always been mint. then again i would go and pick them out at tghe place i would purchase from. my buddy got a b16 swap years ago and got home installed it and ended up getting stuck with an ls tranny

Jimmynitro

Lol yeah I had a a bunch of stock block stuff making power n running good times,, Idk where u from but. Stock B series push 300 all day around here no problems. 300 on stock b is old news

Jimmynitro

Thank you.

I'm from a place that's hot and humid. A good combo for grenading motors.
Plus growing up in a road racing family I was taught a certain way of doing things and I don't diverge from that

A stock bottom end is always a gamble, will a good condition stock bottom end make 300, sure at first. You never know what can happen. I know with a forged motor I can abuse it to a degree and not worry, especially when road course sessions are harder than any pass down a drag strip will ever be

Or just pick up a D16z6 and do a vitara build for less then the b16, able to hold alot more power and be cheaper then a b16... A d15b dont like to hold over 220-250 on stock rods.

It's hard to find custom length rods since FJ shutdown and using stock length rods means a car with a 7.6:1 compression ratio which makes **** power and sucks out of boost

Jimmynitro

I see u know ur stuff. Not tryin to get into agrument. U post alot useful info,,,, But on a b16. U dont need a bigger tb or s2 manifold to make 300 hp. That's just wasted $$. And he only said 250-300 hp. ,That is totally do-able on a healthy stock motor. I agree piston rods b better but at 250 hp that motor will last a very long time. Even being beat on. Jus saying lol. Not bashing u like i said
