I have a b18c with skunk2 manifold, aem v2 intake and greddy headers and chipped ecu. I am going to buy some blox type A racing cams here soon and then get my chip re done by pherable and then get a tune. It says It says i can use stock valvetrain would that be a good idea? and would I need camgears or can I use the stock gsr cam gears. I know on aftermarket theres different degrees but I have been told they are only for looks

 

stock cam gears are fine
you can use the stock VT only if you keep the stock redline.

would i do that? mmm..probably not but then again i wouldn't build a stock internal gsr until i changed the pistons. with 11:5-1 compression you could use the blox c's with a better valvetrain and net 200whp with a good exhaust and a tune.

 

is a hks silent hi power too small?

 

where does he mention this?

also, the greddy header is a carb header which likely means tiny cat. it's not really "too small" i mean the engine will run right. you just often make more power with a 2.5" collector header and exhaust.

it's just with a lot of these parts slap gsr builds as much or more money is spent than if you just sold your gsr engine and bought a a jdm itr. 9 out of 10 times the itr is still the stronger motor of the two due to it's higher compression and likely lower mileage.

 

I would be making more power though with the different cams without changing pistons though just not as much as I could right?

And how hard is it to swap pistons

 

if you know what you're doing it's not THAT bad, but you do have to pull the motor. the blox a's are ITR cams more or less, well slightly more but barely. it's just not worth the hassle of doing all these parts on an otherwise stock GSR. i mean for what you have in it, you could be boosting or starting a good all motor build. high compression and big cams work on these motors. the blox C's cost just as much as the A's and will kill them in power production. you just need more compression. a set of $120 nippon pistons and a fresh hone would really REALLY do wonders to your motor. for the extra couple hundred they and the VT cost you're looking at something like 30 whp of gain since blox A's on a healthy gsr might make 170whp, and that's even a maybe. more than one person has hit 200whp with blox c's and 11:5 to 11:9-1 compression. you'll have to tune anyway, why not do it strong the first time around.

 

Yeah good point but I dont have the knowledge to install the pistons or the money to pay to install them. Would it almost be better to keep my eyes open for a already built gsr block?

 

you don't really need a built block, just a piston swap. what you could do is hold off. not mod anything right now. keep your eyes peeled for a gsr bottom end on craigslist, or a blown engine and build it in your spare time. or, one of my favorites. find a buyer for your gsr engine and order a jdm itr for $2600. this would give you a lower mile motor with no tuning problems since you just run it on the p73. then again if your gsr is in good shape you might just wanna find someone to help you with a piston change.

something like

or

would be what i look into first. get the compression up into the mid-high 11s then look at cams.

 

yeah I have 42k on my motor. Thank you for all the help will let ya know what I decide on

 

I run a set of A's in a 10:1 flat top lsv. I have to say I like these cams for what I do with the car. The motor has good midrange power. Its just a fun little daily that sees occasional trips to 8200. With stock vt the limiter is set to 8500. Is that a bright idea probably not but I have been getting away with it.

 

Thats what i am wanting to do. Is have a quick daily driver but have it still be reliable

 

you have a 42k mile teg? wow, i've never seen a non R that low. if the motor is that fresh i suppose you could do A's, it's just a waste in my opinion to spend hundreds on a couple hp. then again people spend $250 on air intakes that gain far less than your cams will.

 

I bought the car with a b18c1 it threw a rod so I got the car cheap, then I bought a b18c with 40k miles on it. I have the paperwork to prove it and the body has 123k

 

if you have a jdm b18c you have 10:6-1 compression which is MUCH better with the stage 1ish cams you're thinking about running. the A's are a good fit on that motor. i really would be tempted to buy type r intake springs and move your intake springs to the exhaust though. you'll probably want an 8500rpm redline and that's dangerous with the single exhaust springs your GSR, or sir-g motor has. if you keep the stock gsr redline it's obviously a little safer but you still have more lift and a faster ramp.

besides the R intake springs are cheap and totally compatible with the locks and retainers you already have.
