what would u guys recomend for making more power in a NA 13b. I wanna do a carb kit i know to make my swap easier. I also have to rebuild the engine so i might be able to do internals when i do that. Also how much hp does the na 13b make.

 

standalone and nitrous. series 4 n/a makes 146 bhp or something, and series 5 makes around 160 i think?

 

i wanna go carb so that standalone wont work, this motor in going in a drift car so nitrous wont work, u think na will take just a few pounds of boost???

 

weld 6 ports closed, s4 rotars so theres higher compression, do LOTS of trany work. Get the miata gears so you have more brader power band. SUPER ULTRA lite flywheel. LSD. DONE



You don't need much power for a drift car. Just make sure power to waight ratio balenced.

 

know of a good high performance carb kit?????

 

weld 6 ports closed??

S4 rotors are higher compression than what?

super lightweight flywheel will kill the rotating enertia will make breaking traction more difficult (no clutch kicks..).. maybe a midweight flywheel will work. and yes, definitely an LSD.

 

street port, good carb, (well tuned), S5 rotors, 200+ easy....



S4 Rotars...9.4 comp.



S5 Rotars...9.7 comp.

 

look at the dyno sheet section of this site. look at some setups people are using and how they are working.

 

one more very technical question, on the front side of the accentric shaft, what size is the fitting of the hole in the end of it where the harmonic goes

 

you will only make more hp than stock if your carb setup is tuned reallly well.



ive seen alot of guys with carbs actually make less hp than stock EFI with same mods.
