If I were to put Type-R cams from an intergra. in A b16 would I have to change the springs. there are about 12 degree differance on the duration and exhaust.and the rest are not too much differance than stock.

 

Not unless you plan on reving it any higher. If you rev past 8 i would definatly change the springs

 

^ ditto. i run ctr's in a b16a2 with no problems.

 

So doy you have stock springs?

And thanks for the help

 

while you've got the motor apart, I say put in some Type R springs
(or aftermarket) so you can actually use the power band those cams were designed for.

 

I have type r cams in my b16...I run fully stock valvetrain, but I dont go over 8100 though

 

If you plan on upgrading though, you may want to go to something stronger than the stock ITR valvetrain. The ITR stuff is good, but if by accident you slam it into second doing 85 mph, then you're officially screwed, even with the ITR stuff.

 

get some aftermarket u might as well...better safe than sorry...really sorrry

 

So, Bassiclly I'm gonna have to pull the head, or do they make a tool so you can chage the springs while head is still bolted down?

If they do, I haven't found it yet. But you would need the head off to push the valves back through the valve guides to put the retainer on anyways so go ahead and pull it.

there are fittings where you put comressed air in the cylinder, it works I have done it on my ZC few weeks ago and on 2 other engines. Its called an air hold. screws in where spark plug goes. 150psi does wonders keeping valves closed.

Advance Auto Parts sells them, try you local auto parts place, they might also in their tools section.

valvespring compressor

 

you use a valve spring compressor with no air hold and your valves are going to drop into the cylinder. THe head is on the car and he want to avoind the work of removing it.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by CleenSi &raquo;</TD></TR><TR><TD CLASS="quote">

I'd upgrade the springs, and retainers if I were you.

yes i think he was asking what that tool was i wasnt sure tho.

 

JUst be careful not to drop the valve keepers down the oil passage! That sucks! I have been in you exact position, And i dropped one and couldn't find it in the oil pan, so i had no choice but to take off the head!

 

wad up paper towel and stuff the holes before you start, remember to pull them out afterwards. I did that before it dawned on me, luckily I was able to fish mine out on my ZC.

 

I had 2 keepers drop on me, they went to the oil pan though, lucky me. I'm sure they'll come out when I change the oil. If they don't I guess I'll need to get a Spoon magnetic drain plug.

I have ITR cams in my B16, also ITR valvesprings and titanium retainers. I take it up to about 9200rpm just for ***** and giggles. Highest I've taken it was 9500 though....With ITR cams, power probably stops around 8500-8800.

 

My best friend has a 93 civic si that is clean! He has a b16a2 swap that is internally stock! His g-friend took his stuff to over 10k with stock cams and reatiners! That was about 4 months ago! Still okay!

 

Yeah, Well mine seen 9500rpm one time. it was about 8 months ago,Still runs the exact same as before no new noise accured.But last week I heard a noise some where in the timing cover, I have takin it to 3 shops they all say that it is ok. And sound like alot of other cars.

 

With an ITR valvetrain, I wouldn't rev higher than 9100, and you stop making power long before that. A shift at around 8600-8800 is about ideal.
