You obviously don't understand the concept of ustcc then. At least 90% of the time the motor will sit above the 5k rpm mark where it produces it's peak power. Milling is an option, but you can only go so far, itr cams and aftermarket valvetrain are not allowed. Second gen b16 cams are though...as long as they still fall in the b16 family, they're allowed.

No I dont know what a USTCC course looks like, i assumed you meant parking lot solo type ----, tight turns.

Mill that ------- head with some itr cams, ported intake and stock t/b, spendy exhaust manifold if youre aloud, great tune and 94 octane

200whp N/A pylon stomper

USTCC has class specific rules for the chassis. Minimal aftermarket engine mods is one of the rules, no itr/ctr/gsr cams. They must be stock b16 cams, but one's from any gen b16 can be used. It's a touring car class, so it has similarities to scca solo events, but it's all done on track, and you're actually racing against other drivers instead of their times. I still have a few more hours of class time, and then some track tests before I get my license, but I think my old vscca license may hold some sway with the amount of time I have to put in. They're very strict and harsh with track rules, if they applied the rules to nascar you would only have a handful of drivers out on track throughout the race. :P

Dude there's a boatload of ---- you can do. Get some CTR pistons, headwork...yada yada yada. Don't both the B16 and C5 have the same marking on them? Do they pull the cams out to measure the lift or something? Just build a poorman's ITR but with a B16 shortblock.

i could've sworm that the c5 markings are p72? am i wrong?

Well honda challange I know was tearing ---- down so Im sure if someone is making 30+whp of the comp something is up



Factory ported manifold
68mm tb
ported head 300 cfm
stock valves
p30 cams
p30 pistons=ctr's are asking for doom



Good head you should be around 175 whp. I love how everyone thinks 200 whp all motor on a 1.6 is easy



I would also replace the old beat up factory springs with some crowers since the motor will be seeing high rpm's for minutes at a time last thing you want is a 20 year old b16a single spring set up in a motor :1




But Ill quote the rest of people who have never been around this kind of stuff



skunk2 boyyyeee 200 whp b16a=walk through the park my boyee makes 250 on his lsvtechhhhhhhhhhh

Lol...nice. Chris has the lowdown on b16 work, that's why I love picking his brain. Pretty much what you posted is probably what we're going to do...the headwork itself is going to be the hardest to do.
Lol, I appreciate your enthusiasm, but like stated ustcc has rules you have to follow for engine mods. What they do is "huff" the engine. Basicly it tells them what size the displacement is and how large of a cam you have in the motor by the amount of cfm that flows through during the test. If you don't fall into their test parameter range they make you take the head off and cams out so they can visually inspect it to make sure. It's all about levelling the playing field so nobody has a particular advantage and it brings it down to driver skill and suspension setup.

While were on the topic of throttle body sizing I dont care what the hype is. 65mm+is what you want for any all motor dohc vtechhhhhh build



Hey if you want I have 68mm tb's in stock



The headwork for sure is where your going to find the power. Good headwork and good mild cams=best of both worlds

Slo_crx1

Do you normally see gains on a 65mm+ tb? This might be something I want to look into for my ls/vtec...

Guy-Fast

yes atleast 6 whp+ in higher rpms but will lose some torque down low but its all motor rev the ---- out of it
