i got my 20b started with the stock twins, and it revs way faster than the 13b did. its got me thinking to take the turbos off, how much hp do they make with no turbos?? and stock ports??

250 to the wheels would not surprise me...
Horsepower is not what I'm wondering, it's the torque that's going to be an eye-opener!&nbsp Torque numbers should match horsepower numbers or be very close!&nbsp A 13B 2-rotor would typically be 15%-20% behind in torque versus horsepower...

There is a tuner in japan that had/has a 3 rotor n/a with either a BP or a PP, and they were making around 460hp, and I am pretty sure that was rwhp..

 

hmmm it would make all the plumbing easy, still have a bunch of torque, and run forever

yup yup now get stared on your n/a 20b project chop chop!

Since you'd be using a custom header. Where would you collect the 3 pipes to tune the exhaust pulses together? Long or short? All together in one big pipe? Or place a 3 way collector in down stream?

I bet someone knows where a pic is? I had heard Mazdatrix had put one in a drag car?

 

I think Mazdatrix's car has three semi straight pipes which run back to a single muffler. As to how they're collected, maybe it's Dave's dirty little secret. For him to know, and us to wish we could know. Heh, well maybe not. So who knows for sure?

 

Nope it was the black FD, I think it was Top Fuel's but I could be wrong, also RE Amemiya's GT car has a n/a 20b definately well ported though making around 450hp..

 

i dunno about the headers i was just thinking out loud, the long ones work great on a 13b.
