Hey, guys... This guy I know is selling ITR cams and valve springs(10,000km on them and off a '99 ITR!!) for $300... I'm sure they fit in a B16 but are those(cams & springs) the only parts I need to install?

What else(parts) do I need? new retainers? new ITR valves? ETC, ETC...

PS. is this even worth it?

Thanks in advance!

 

They are definatly worth it for that price. Not sure if you need the retainers...I have also heard the ITR lost motion assemblys are a nice thing to add as well...

 

Get the springs and retainers if you're going to rev higher than 8k RPM.

 

I know the R has dual stage springs on the intake side (I think) but I would try to get both sets of springs
see if he is selling the ECU as well
Oh and for the price you will deffinately like the gains!
(I dont think they make ITR's in 99 BTWN)

 

what's a lost motion? I don't know much about ITR motors...

are the ITR retainer really needed?

Thanks!!

 

they did... in Canada...

and yes, I'm getting the in/ex ITR valve springs...

 

He is from Canada. Type Rs were available in 1999 there. Sounds like a decent price. What ECU are you using? I also heard something about using the ITR LMAs, not sure if it was meant for more aggressive aftermarket cams like Skunk2, etc. With some tuning you will see nice gains..

 

I'm using 2nd Gen. OBD1 B16 ECU... I don't know about the codes(p28, etc, etc, blah blah)... I go by generations(yr)/makes... 'cause they always confuse me...

more about the LMA!!!

PS. Do I really need ITR retainers?

You can just throw the cams in there and run them hard all day, but if you want to rev it past 8k, you should do the valve springs and retainers from the R as well. Can't beat that price, go for it

 

I CAN just install ITR cams using B16 valve springs?

and also, ca I use my stock B16 retainers with ITR valve springs?

Thanks, guys!!

 

Yes but you won't be taking advantage of the cams as much if your stuck under 8200. If you can get all of it, go for it and be on the safe side.

 

i put the type r cams in with stock valve-train...it will work but like everyone said, if you can get all the parts for a good price, get it and do it right

 

i have 01 itr cams i changed the springs and retainer is just better piece of mind..

 

Yes, I've been running CTR's on a stock valvetrain for a year or so with no problems.
BTW, what's the difference between ITR and normal B16 retainers? I heard they were the same?

 

I also want to know...

Thanks a lot, guys!!!

 

so... as long as I don't rev more than 8200RPM, it should be OK with stock valvetrain?

hmm... maybe I should do that first and install the valve springs later when I have the $$ for safely(fully) built valvetrain... yum...

I've been up to 8200 a couple of times with no problems but I usually stay below 8000.
Really need my ITR valvetrain installed soon, no use them sitting under my bed in a box

JDM 2nd gen B16A and ITR retainers are the exact same thing

1st gen B16a MAY be a little weaker but it hasn't been proven yet.

I run CTR cams in my JDM 2nd gen B16a with ITR valve springs and stock retainers and I rev to 8500rpm safely all day long and know guys that have the same set up also that have done it for years.

Also regarding the LMA's(lost motion assemblies) it's over kill to put them in with CTR/ITR cams yes you can do it to be REALLLLY REALLLY safe but it's only really recommended with more aggresive cams like JUN,Crower,Skunk2 etc etc.

 

Honestly, i hit 9k on stock gsr valvetrain a few times with no noticable anything, except a little power loss. IF you can get the ITR stuff cheap, do it. If not, drop them in and stop at 8500.

 

oh and what about the valve clearence? what size filler? ITR spec ok?

Thanks!!

 

Go ahead and do the valvesprings. The ITR retainers are the same as your b16a so I wouldn't really worry to much either way. If you want new retainers, they should cost about $35 for all of them at a dealer. I wouldn't really worry about it though, I would do the valvesprings for sure though.

 

What I wanted to hear
One more question, whats the best way to store LMA's? I heard you're supposed to keep them in oil??

 

He shouldn't go to 8500 if he doesn't install the ITR valve springs and just has stock B16A valvetrain. On stock B16A valvetrain it's 8000-8200. Like I said B16A and ITR retainers are the exact same thing and with the ITR springs you should only be taking it to 8400-8500 at most on a regular basis.

Stock redline on an ITR is 8400.
