Ok, I did some searching and found out some quality stuff!!
Heres what im thinking. I want to install some ctr or skunk2 stg 1 cams on my b18c. But at the same time I may as well do the springs too.
--Valves--
I found out that the itr valves were the same as the gsrs on the exhaust side, and just a hair lighter on the intake. Im thinking I should just leave these alone..?

--Springs--
I am thinking about just getting itr intake springs, and putting the gsr intakes on the exhaust side..? Good idea?

--Retainers--
Should I upgrade these? Do I need at least new itr intake ones?

How high can I rev this setup safely? I heard 8,400 and I heard 9,000? What yall think?
Thanks so much, Ryan

 

Everything you are thinking of is fine. ITR and GSR retainers are the same, so no need to change them, if you are sticking with stock. Another option you might consider, depending on budget concerns is all ITR intake outer springs with Portflow inner springs. With the cams you are talking about running, no need to go much past 8,400, you won't make power up there.

 

Ok, so ctr, and skunk2 stg1 cams stop making power past 8,400?
And, portflow inner springs would be better how?
Thanks so much. Ryan

 

Im about to do the same things with my GSR. Good thread Also would you guys recommend the Skunks over the CTR's and is it worth the extra $...thanks

 

b19coupe is right.

budget valvetrain setup that's really kick *** is the ITR outters and portflow inners.
ask tom at portflow exactly why his inners are good stuff.

you'll be fine till 9k easy with the setup b19coupe suggested.

 

Ill check out the port flow inners then!! Thanks. Also, is safe reving 8,400 or 9,000 Thanks, Ryan

Safe to 9,000 but you won't need to go that high with the cams you are considering. My Skunk stage 2's peaked at around 8,100 in my stock block ITR.

 

Great!! Thank you. Ryan

 

Where is a good place to find the portflow setup? I found the whole thing, inners/outers on inline4 for 195.00 is that good? Ryan

 

Tom charges $200 for ITR outers and Portflow inners.
http://www.portflow.com/frame.htm

It is the going rate.

 

OK, I just purchase some one week old skunk2 stage 1 cams for 475 shipped. Good deal?

Now I need some v springs....
Would portflow inners/itr outers be overkill since these cams dont make power past 8,400? Or is it reccomended?

option 1
portflow inners/itr outers

option2
all itr springs inner and outer

Please help. Ryan

 

I pretty much bought the same setup you have.

It will not be total overkill to run the Portflow/ITR combo on your motor. Having a fresh valvetrain is better than having an aged, saggy one.

 

Thats true I will prolly just purchase the portflow ones.
Any thoughts on retainers? Is there any reason that I should get the titanium ones?Ryan

you got a good deal on the cams.

option 2 will be cheaper and perfect. But if you plan on changing to larger cams, option 2 is your choice.

 

Well, the dealer wants 185 plus tax for the itr set.
And http://www.jhpusa.com/ wants 190 shipped for the portflow ones. At this point portflow wins. Unless I can find some brand new itr springs for real cheap. Ryan

If I did get titanium retainers would it be beneficial with the skunk2 stg1, and portflow/itr springs? Since I am in there anyways... Or is it a waste of $$$. Thanks

 

well, somewhat a similar question as ryan's

what is the benefits for ti retainers...is it needed or not nessary vs OEM. Im getting skunk2 s2 and also the same itr out, portflow inner spring set up...but not sure bout the retainers...WHAT ABOUT THE VALVES QUESTION, change or keep the oem gsr ones...how does the change of valves benefit the engine..

 

I heard that aftermarket valves sometimes need valve jobs too. so its like, leave it somewhat stock(mild) or do a full head build, its tuff to know when to stop on a light build up!!

I just did some searching, and it said that stock b series retainers are cool up to 9K, I dont think I have to worry. My setup will look like this... what yall think?

Jdm b18c in a crx
I/H/E, Skunk IM, Skunk stg 1 cams, portflow/itr v-springs, Act full disk clutch, hd press. plate, fidanza flywheel

I need some ecu mods... Uberdata??

Sound like a winner? Ryan

sounds good. what kind of header?

 

Just a dc 4-2-1, I need the ground clearence, and the carb#.

Im going BAR cert.

The cams/springs/fuel management will be installed after the BAR

Ryan

 

why dont you wait till after the BAR and get a real header?

or you can chop off the DC's carb # and have it welded on the 'real' header...then paint everything the same color

 

Thats a good idea... What kind, its gotta have good ground clearence tho... Ryan

 

DTR(~900?), SMSP(1000), Hytech(1300) all have GREAT ground clearance and i'd say are the top three headers out right now performance wise. Headertech also has good ground clearance if my memory serves me right. Headertech is good bang for your buck since its only ~600 i think and performs really well.

Don't cheap out on headers since it will make a HUGE improvement on your engine's performance...especially compared to a USDM DC. You won't be disappointed in spending the money on a great header.

 

Allright man, I have the dc allready, and its used... so Ill try it for a lil while, then, when upgrades come (cash is more abundant), I will definately look into that one!! Thanks, Ryan

 

i have a weapon r header, same as hytech and the ground clearance is a little low...but drivable...man this header is good, and i think its so good...hytech is actually charging over a grand for theres.....
HOWS THE UBERDATA? Havent heard any opinions on it yet....
