I figured i should share some of my 20B swap stuff with you guys over here. I was guessing i was going to make around 230-240HP and i ended up making a best of 228 HP on my final tune with my exhaust and air filter on. I ended up routing my exhaust through the stock TII catback and i'm not running a cat on it. I then ran the car again with open header and no filter, i got 233whp. Heres the video and graphs from yesterday: (my engine bay is dirty again, so hush)

First and last run:

 

cool deal, i was thinking of doin a na 20b myself for mynext project.

 

very cool to see the exhaust header glowing red hot too!!!!!!!!!! i bet there is more power to be had with that motor with a little more tuning.

 

Nah, I'm pretty happy with where i'm at 13.2 a/f and 24* Advanced timing. That puts me right where i want to be. I'm currently running 0*split so i want to be on the safe side.

 

i've never seen an 20b n/a dyno.......that is decent but not great ?



also it sounds like something is wrong on the dyno video???? weird....

 

Nobody said it was staying n/a.

 

What is done to this motor besides the header? Is it rebuilt with higher compression rotors or anything like that?

 

i second that notion...what else is done!?!? im planning a 20b N/A FC3S myself. what power should i be looking for??????????

 

Recon that 233 hp. is all there is in a NA without porting? I'm putting my 20B in an airplane and sure planned on it turning out about 280+ hp with a street port. I need at least 280hp out of it.

 

My extend port is making 245rwhp with stock rotors. This is on a dyno dynamics which read 15% less than a dynojet & other American dynos.



This would put it up over 280 rwhp over there.
