hey i have a 98 jdm b16a mods are
skunk2 tuner1's w/blox cam gears
1 piece headers w/ test pipe
intake
itr valve springs

i was wondering if i should get it tune?
or shuold i wait on my ctr pistons and maybe upgrade to a stage 2 cams?

JDM_7

Probly wait, you'll have to get it retuned anyway

phaphon

yea thats what im thinking but people said i should just tune first cause it makes a big difference for now but i mean instead of getting it tune i can get the ctr pistons with that 150 but i still would like to upgrade to arp rod bolts and still gotta want to wait for the sk2 manni and tb damn y things gotta cost money lol

phaphon

no opinions?

From what I can gather, your motor is close to stock, stage 1 cams are pretty mild. I would probably wait so you spend your money for a tune when you really need one.

RCurioso88

i would definitey wait especially if you're going with CTR pistons and stage 2 cams. Plus it'll save you money since you won't have to retune it later. It won't matter if people say it'll make a big difference now, just wait till you get it how you want it and tune it. Then you'll see a BIG difference. I had to get my lsvtec tuned cuz 12.1 CR and BC Spec+3 cams didnt sound too safe to me. GL with it

Anytime you make a change like swapping cams, it's a good idea to get a tune. Not just for the extra HP you'll get out of it. Yeah, it costs money, but it could save you down the line. You could be leaning out at full throttle and not even realize the damage it's causing your motor. Your call.

yeah kinda sounds like i needa tune but at the same time i still gotta figure out how long this build is gonna take me in the mean time i dont really drive my car much but when i do its out of town and yeah i had a question is there is difference in the tuner1 and tuner2 cams from skunk2? cause they are both the same price? if one was better then the other why would it be the same price?

fungus mungus

The Tuner stage 2 cams are more aggressive cams than stage 1. Stage 1s have close to the same primaries as stock...the vtec lobes are a bit more aggressive than stock. More like CTRs. Stage 2 have a larger primaries than stock in addition to a much more aggressive vtec lobe than stock. Stage 1 cams are CARB legal but Stage 2 and 3 cams are not, if that tells you anything.

Stage 1 cams will not require an upgraded valve train, but Stage 2 cams will.
The reason they're the same price is that the same amount of R/D and manufacturing costs go into them, regardless of what stage they are. They simply suit different engine builds. Keep that in mind if you decide you want Stage 2 cams in your current build, you'll need an upgraded valve train, which adds to your cost. So they don't really cost the same to put in your current build.

so it itr valve train wouldnt be enough for the stage 2s?

fungus mungus

No, I think not. You're asking for mushroomed valves.

ok.. but yeah im having second thoughts about getting ctr pistons...is it really that much of a difference from my p30 pistons ? im not sure about on how to install it do i need to get my cylinder hone? and im not sure if that is pricey? if anything i do want to go lsv or b20v soon later on down the rd should i wait till then to go with high compression pistons?

i would get your ecu flashed, give the guy your car and engine stats and mods and let him chip your ecu. i used phearable and had great results. car runs very well and is daily driven

fungus mungus

If you're gonna pull the motor just to replace the pistons, you should redo the rings. It's not going to be cheap if you don't do it yourself. A couple of grand for a typical rebuild. The ctr pistons will bump your compression a bit, so with cams, good airflow (intake&exhaust), and a tune, it will make a difference. Whether it makes 2-3k with of difference is really up to you.

phaphon

well i got a good deal on a sk2 manifold its not the pro series one but it was out of the bag never open and i got it for 30 bucks but i plan on doing the ctr pistons myself just wondering what do i need to put them in my b16 i will do pistons rings and rod bearings and arp rod bolts

RCurioso88

if you're planning on doing lsvtec down the road, why not get the car tuned now and save up parts to do it all at once. You don't wanna keep tearing your motor apart so save up your ctr pistons, new cams, your ls/b20 block and do it all at once. It'll take time but patience will reward you with reliability. At least it did with me

phaphon

well i mean everything for my head is already on so yeah thats what im thinking about for the ctr pistons is wait for the ls or b20 bottom block then build it when i have all the parts for that but in the mean time would it be a good idea to get my car tune? lol well im guessing yea so i think thats what im going to do once i get my timing on correct...cam gears i bought had no timing marks on the side so i guessed when i put it on it runs and drive fine but when i floor it it bogs... is that the timing ? and is that something the tuner can fix for me or will i need to do it myself?

phaphon

another question that came to mind is what size tb should i get and injectors

KARSON

62-68 is good enough for all motor depending what ur doing with it.440 injectors are as big as i would go, but it differs on what you want to do.

phaphon

i dont think its gonna be a crazy set up so i was thinking 65mm and 310 injectors

phaphon

my set up right now is sk2 tuner1s sk2 manifold str cam gears itr valve springs aem fuel rail and thinking if i should get injectors but i know i want a tb for sure

chewyv

since your already spending all this money might as well go get a tune while you wait for parts. your stock injectors are fine for now.

phaphon

ok since my injectors are good im just gonna get my tb and go tune and i dont drive my car much so i think it should be good till then

phaphon

hey well i went with a turbo setup with the same set up as listed above...on the dyno it
got 233 whp with around 150 something torque the tuner said i should be gettting about 250 but i need a adjust my valves (they're a little to tight) now my question is what you think i should be getting in quarter mile?

fungus mungus

Where was this tuned? What chassis again?
