I know how to do the actual installtion part...but I have a question.

I ordered Integra Type R outer springs and Portflow inners. I received the Portflow ones just now and from the looks of it, they are all teh same...so Im assuming it doesnt matter which goes on the intake and the exhaust?

How about the ITR outer springs? Is there a intake and exhaust spring...or are they all the same?

And finally, do I need to check the installed height? Mike K said he never checks it and has had no problems. How would I go about checking if I do want to do this step?

yes intake and exhaust are different.
The intake springs should have yellow paint on them

HX_Guy

But the inner springs are all the same?

Mike K

When using Portflow inner springs and ITR outer springs, installed height is right on. I've never seen any problems with it.

Install all springs with the yellow paint facing up.. and the Portflows in with the more coils facing down.

uhhh doh... when i put in my portflow inners they look about the same to me. i guess some of mine might be upside down. hmm can't remember exactly. shucks.

HX_Guy

Hmm..Im sitting here staring at the Portflow inners and I really dont see a differance between one end and the other...looks the same to me.

Yeah! I would be worried when I had installed them upsidedown. The coils gets slightly together on one side of the spring. Look carefuly.

I had luck when we did the valve springs swap. We figured after the 1st spring out, that there is a different in the coils. Lucky we saw this!

I don´t know if it does matter when you put the spring 180 degrees wrong in. But for some reason they made the coils so. Damn! you must lift the head again!

yeah i have the inners also and they look the same to me. but i hear this set up is a bit better than the JUN set up

HX_Guy

Alright...just got off the phone with Portflow.

They said their inner valve springs are non-progressive...so there is no top or bottom to them
Also for the ITR outers, he said to use all yellows with the paint up liek Mike said...and sicne they are all yellows, there is no differance between the intake and exhaust springs.

ghettoracer

coo. 'cause i remember i stared at them for a while and they seem the same at both ends...
