Yeah, Im probably going to try and get these in some time in June. Besides these cams and the OBX header, Im probably going to be done with the car for a while. Turbo is in the future (after the car is paid off and my CCs are down a bit). If I do any more engine work after the I/H/E cams etc..... I'll maybe get some port-n-polishing, head work. Open up the TB and port match everything. Thats bout it!
man i never noticed there were so many parts out there for the 1.6L's. The only thing i've heard that will make a big differnce is getting a Turbo kit. As you guys already know those kits aint cheap at all. But i would love to drive a 1.6T one day. Diffentely bring a tear to my eye.

I know im bringing back an old thread but i was just wondering if there is any news at all on cams for 1.6L?
since you brought back an old thread..
if people are looking for n/a power out of the 1.6l, using a stand alone engine management system and aggressively tuning the air fuel ratio and ignition timing with race gas, E85, hell even 93 octane pump gas could probobly get you close to 130HP.
Think about it, the stock ecu is tuned for people that run 85-87 gas. Add a cold air intake and good fuel to resist detonation and there would be plenty of room for improvement even using the stock equipment.
Its all in the tuning. Shaving the head would be a cost efficient way of bumping the compression also if you can afford some downtime.

I read that a member of another forum felt a difference with the cams after 4000rpm. Would this be a worthwhile mod when one intends on going forced induction or would the stock 1.6L be better suited?

along with my intake, im looking at getting the obx header w/o exhaust, and i shall stop there unless i get a cat-back, in which i will keep OEM muffler. any comments on that?
i remember reading the obx header was a power getter.

If you just get the header and stick with a stock exhaust you won't see too much improvement. You'd be better off with a catback system. You'll feel more of an improvement. Ideally the header with the exhaust would be your best combination.

You could always slap on the MPS Racing Beat exhaust.

whats restrictive the muffler or the piping, both?

Both, if I remember correctly the piping is 1 1/4" and the muffler is pretty restrictive what with all its turns and such. You could just have them cut off your old muffler and weld on a new one but with that restrictive piping in the middle it wouldn't help too much.
If you were to put the header and say a 2 1/2" piping but with your stock muffler it would be like a 4 lane highway squeezing down to a 2 lane.
What I would do is start from the rear end. Get a catback and then move back towards the header if you like. I'm running a Hayame catback right now and I felt a difference in performance. You're not going to beat out any Speeds but you'll have a bit more HP to pull you through the turns.

theres some ebay axhaust for 150 shipped. shud i buy one and use the piping from the cat to the OEM muffler?
IMO A 1.6L putting out less than 200 hp would be fine with just 2" or 2.25" piping with a high flow car. You dont wanna go too big of a pipe as backpressure is still desired in an n/a setup, just not as high of back pressure as the stock system.
If you ran the header and ditched the car altogether you may be fine with the rest of your stock exhaust and muffler. im running stock axle back and muffler on my msp and its nowhere near 2.5" and flows fine even at high boost.
I still think the best idea for making power on these 1.6l would be to retune the a/fs and ignition for 93+ octane pump gas. Your ecu is designed for really poor fuel and have very conservative tuning. I bet a 93+octane tuned 1.6l thats otherwise stock would make more power than one tuned for 87 with I/H/E bolt ons. Then if you wanted to add the bolt on later you would make even more power as you would be able to tune for the new modifications.
