Hello,sir,

I need info wich modification i can't do for get more power, torque for

1,6l B6-ZE engine found 1 gen miata

Dosen't woudlike put turbo or supercharger. I woudlike do in N/A

Since forced induction doesn't suit you, how about an engine swap? The BP-ZE is more or less a direct drop in and will work with the stock ECU. That'll only bump you up by about 15HP and about an equal amount of torque.

If you want to stick with the B6 in NA form, an intake, header, etc. will yeild a small amount of power, but nothing to really make a difference. Your best option for NA power is to implement an "aggressive" cam grind (suited to your purpose of course - street, track, high RPM, low RPM, etc.), balanced and blue printed bottom end with higher compression pistions, lighter rods, head shave, block decking, etc. Aftermarket engine managnement would be a must.

It is my opinion, as well as others', that a turbocharger or supercharger is probably the most economical method to persue. The B6-ZE and BP-ZE can take quite a pounding with forced induction and continue to zoom on.

Hope this helps!

I spend $$$ (I/H/E, head shaved, freeflo cat)to get 15 whp on my 92. For that amount I couldve gone the base Greddy turbo route ( $1200.00) and got 35-40whp and more room for zoom for a little bit more $. Kevin's got a good point. Hp/$ go FI.

Hello,sir

thank all for the information

I woudlike know how much hp and torque and can get 11:1 pistions, toda or orther brand?


how much hp and torque i can't get with agressive cam shaft?

thank

Unfortunately with such modifications you listed, you can't just install them and hope for power. High compression pistons by themselves will yeild a bit of power, but not as much as "overall" potential when matching camshafts, engine managment, etc.

Camshafts, too, are not just a bolt on part. "Agressive" cams will cause drivablity issues and can perhaps lead to undesirable results in certain portions of the powerband.

To build an N/A engine that yeilds significant results over it's base, stock power output, part matching and stand alone engine managment are required. By "part matching", I mean camshafts and compression ratios need to be designed and matched for a specific power band portion and the intake and exhaust systems need to be designed to complement and work with said internals.

Building a powerful engine is not a bolt together process. Engineering and design all come together. It's hard to say what any specific part will do in one car given what modifications have or have not already been performed.

There are sources that have produced off the shelf parts already and have dyno numbers to state their claim. However, these parts were peiced together with already installed modifications to the car's engine or just a stock engine.

All in all, this is a very basic overview of the thought and work required to build a worthwhile N/A engine. There are several folks on this board that have done so with Protege engines; you may want to take a look at a few posts in the NA sections for some insight. Additionally, research other forums such as Miata.net for a load of excellent info.
