Hi, i recently bought a 1997 EK4 B16A2 with fully forged internals, 11:1 Compression, Mugen 4 - 1 header, Spoon Titanium Valve Springs, Ported head and a hondata s300, it's currently making 182 hp (im not sure if it was ever dynod so it might just be an estimate)

Im building the car as a road legal race car, im trying to hit 200whp so if have any knowledge please leave your opinion.

Im currently considering:

- Skunk2 Tuner Stg 2 or 3 cams

- Some sort of ITBS (because i love the sound)





Sadly swapping to a B18 or B20 block is out of the option because of local laws and availability.

Lol. Then so is getting 200WHP.

Also Pro 1 cams are as big as I would go with your compression ratio and displacement. Pro 2's are absolutely too large. Tuner 1's may even be a better all around choice.

If you wanted to dump a lot of cash, sacrifice some reliability, and actually get 200+WHP you could do a stroker kit. It's not generally recommended on B16's due to the fact there's bigger OEM blocks to work with, but it's an option.

 

how did you come up with the hp figure if it was not dyno'ed?

what type of racing are you looking to get into?

only issue with a b16 is the lack of tq.

if you are at 182whp, i would probably estimate your tq to be maybe 130.
which is more than enough to have a great time on a road coarse with the b16 trans.
invest in a set of nice tires and brakes and go all out!

i can only assume your goal to hit 200 whp is just for show

 

With something like skunk2 tuner 2 cams you could get up around 180 wheel hp. You are definitely not making 180 now on stock cams.

A ported B16 manifold is pretty much the best thing for your setup, but ITBs would work as well, just make sure to put some long stacks on there. Dont find yourself thinking just because it revs high that you want crazy short runners. The length of the runners on the B16 manifold is really good.

To make 200 youre going to need more compression, head porting, and youll have to optimize the whole setup (cams, intake manifold, header) to make power at 9k+ rpm.
