The test is done to see what I can achieve without spending to much, so that I could have something to offer to ppl that want to buy "hp in a box" fairly mild cams, and a great head upgrade.

Stock B16a2. ported head, RL Stage I camshafts.

"Wanted to build this for drivability, and more tq without adding compression,"
Tuned on pump gas.

Blue line shows baserun, stock motor with Header Intake and Exhaust H/E/I.
Purple line shows the same setup with Ported head and Race Lab Stage I camshafts. camshafts at +4 Intake and -3Exhaust. engine love big Overlap/tight lobe center. not like regular b16*s

Tried to add a intake and reconance tuned it +2hp
adjusted exhaust cam -2 from previous setting +2 hp the rest was in the setup and tune.

What could been better?
Better header! This is a spoon replica header with a not so good collector
Upgraded crank ventilation (Damn what a crank presshure at high rpms)
bigger camshafts combined built bottom end.
Still 182whp on stock bottom N/a is pretty good.

Tq numbers are in Nm, converted to ft/lbs it is something like

Stock with H/I/E 94ft/lbs
Modified: 128ft/lbs

 

That's not bad at all and has lots of promise for guys who want to play with the "little" motors. Apply an ITR bottom and 200+ is right there for the taking. Good work. Simple.

 

Indeed, I would add some crankhouse vent to the package, but yes 200 would easy be acheved With 1,8litre.

 

What lube is in the cams in that shot..looks like silver anti seize?

Anyways, nice work.

 

good stuff

we have seen 174whp @ 113lbs ft torque (dynojet) on one motor before
(we rarely see anything over 112lbs ft torque )

using pro1 cams , p30 intake manifold + 62mm TB

if you are using that intake airbox (stock eg6) it would prolly be better to run an aluminum intake pipe from throttle to the airbox vs that air duct u use...
it should probably replicate the +2hp u see with an open intake pipe w/ filter set up

good job though... i think 190 should be possible even more...

that header i agree.... its holding back a few horses on the stable

 

The stuff that looks silver on the pics are actually super slippery molycote assembly lube for the cams.


here is a dyno video..
(About the intake... I added a aluminum tube and a open filter and gained... 2whp ;-)

 

good stuff we see very similar improvements on the stock airbox by doing that change on the intake pipe

 

Thanks! The funny part was that you "guestimated" 2 whp, and it did! Good work youself!

 

maybe im claervouyant LOL (joke)

i dont even know how to spell it haha

 

Maybe so, (Dont even know what that mean)
