Hi I am planning my first Turbo setup. Right now I have a JDM b16A in good shape with the LSD trans. I am aware that the GSR engine is a little better for boost... Both are similar but the B18 seems to have better cams for turbo, is a little stronger and will provide a slightly better power band.

Worth it to upgrade to b18c1? Not that hard, but adds some PITA factor. Could do LSVtec, but that would make things too complicated at this point.

Using peakboost style kit, with disco potato (GT28RS) turbo. Also, is there much of a benefit to upgrading to an inline pro log manifold over the ram horn?

Looking for 300 WHP, decent reliability, nice power band. Few road course days per year, running full size rad, and an oil cooler. Both engines and manifolds will obviously work, just wondering if these upgrades are worth the extra time and money... Thanks!

 

I would just keep the B16 and IMO the ramhorn is a better manifold then the log. All you need to do is swap some gsr cams into your head and your basically running the same thing, just missing some displacement and a few tq numbers. 300whp is easy to get with a decent tune and a good setup and still be safe/reliable.

 

i see thanks for the input sleeper.

 

pretty much what sleeper said! my b16 was fun, only thing gsr's had more than me was torque, which you don't always need more of in certain cases.

 

it just seems pointless to do all that work for 15-20 more ft lbs of tq when you can get some gsr or itr cams in the b16 and make up for it in the power numbers.

 

Keep the b16a head, and pick up a gsr block/crank.

 

hes absolutely right, except if your using your car for racing.
every little bit counts and helps.

 

it all depends on your power goals and your budget

no replacement for displacement as long as you can put that power to the ground

in your case you are probably better off keeping the b16 and doing headwork to make the extra power (itr cams and valvetrain would be perfect)

and ramhorn is better than the cast manifold in almost every way

 

If your just planning on 300HP and running the GT28RS, stick with the B16. It will give you what your looking for.

to the 3rd power

 

X4 You can easily make 300whp with a b16. Instead of doing a swap just by some upgrades. Cams, cam gears, Intake mani, ect. Have fun, boost is addicting

 

I say stick with the b16. It can make just as much power as a gsr. I would spend the money somewhere else. Theres a thread on here somewhere with a list of the highest hp stock motors. The b16 has the highest figures

Thanks guys for all the input. I guess I'll stick to simplicity then. Really looking forward to this. Interesting link...
