hey guys, ive been looking around and i came across this ebay turbo kit for a b. I know that it wont make my 2.0 very fast in any kind of way, but im looking to do something a little different than most people do. Everyone just tells me to rotary swap or fe3 swap, but i think the turbo 2.0 would be something cool to play around with. But knowing that the b-series motors are not very strong motors would it be safe to run boost through a stock motor? maybe just 5 or 6 psi? What is your guys imput about the kit and how much boost a stock b2000 could safley run? Any input is always helpful.

Heres a link to the ebay kit.

in my opinion (and from what ive heard) i would highly recommend staying away from turbo chargers/kits on ebay. cheaply made turbos and manifolds have been known to blow and crack. and that could cause other problems with your trucks motor.

You might want to look into finding a turbo setup from an mx-6 or finding a donor mx-6 to swap the engine and all the wiring for the fuel injection. I would be kind of leery about getting that kit with the no name turbo. Look around on mx6.com as well, there's a lot of people that are very knowledgeable about the f2 and f2t engines.

have a shop build you a setup, t3/t4 combo wouldnt be bad off of ebay. they sell good stuff and bad stuff.
imho buy a manifold and a turbo and build the pipes yourself
your motor will be fine under 5-8 psi.

I know everyone has heard this... but it is true "you get what you pay for" A good kit will cost anywhere from $1500-$2500.

and just slappin a kit on is gonna make it run bad anyway.
I don't see the stock fuel pump doin any good, prolly same w/ stock injectors.
and you're gonna need engine management of some sort.

While adding a turbo is a lot less drastic, this reminds me of an article I read about boring out motorcycle cylinders to increase the engine capacity and supposedly power output. However, it doesn't work.

If you bore the cylinders and upsize the pistons then your intake and exhaust ports will be undersized so if you really want more power you need to machine those out to be a little bigger and replace all the valves. Now your intake system is undersized so the engine is starved for oxygen unless you replace all that and/or add a blower (and/or nitrous if you wanna get crazy). Maybe your fuel system could still keep up but really you should re-jet the carbs/upgrade fuel injectors and maybe other fuel system parts like a bigger pump. Ok, that's cool but now your exhaust system may very well be undersized and the backpressure will rob power from the engine unless you replace the entire exhaust train. So after all this your engine's kicking ass except it's burning fuel faster and generating more heat. Can your cooling system handle it? I don't even know where to begin upsizing a cooling system but I suppose a smaller gear/pully on the water pump (if possible) could do it along with a higher performance radiator and larger fan(s). On an air cooled bike this isn't even an option and you just have to deal with the engine running hot.

$15k later you realize that you could have just bought a stock Hayabusa with way more horsepower than the bike you completely rebuilt. The author claimed that after a long career working on bikes he had never seen performance upgrades that were more effective than putting that money towards a bigger bike. I suspect this applies to cars and trucks too. I seriously thought about buying an Ariel Atom. It's a supercharged 2.4L car that only weighs 1350 lbs so it does 0-60 in 2.9s stock.

My b2600 is fast enough for me. It tops out around 90 mph which is more than enough to get speeding tickets in any state. And I don't mind waiting 90 seconds to get up to 60mph.
