I have the b17a1 out if the 92 gsr and was wondering if I would have any valve clearance issues with skunk pro series stage 2 cams and ctr b16b pistons stock b17 crank and rods skunk alpha series springs valves and retainers please help I have a gut feeling my pistons are gonna mess up my valves :/

 

clay the engine to find out.

 

how do yu clay the engine what are the steps / processes

 

Here: i know it's a d-series but same process http://www.d-series.org/forums/showc...rated-fun.html

 

i have another question at any time in the engine is the piston up and the valves completley down? or do they close before the piston is at TDC?

 

the closest you'll get to that is on the exhaust stroke.

 

so basically i should be fine with the stage 2 pro series cams
and the b16b pistons?

 

clay it first then degree the cams(or other way around) don't just start the car up untill those 2 have been done.!

 

what do you mean by degree? do u have to have adjustable cam gears?

 

You HAVE to degree the pro series cams from skunk. here is how to http://www.hondatuningmagazine.com/t...s/viewall.html and adjustible gears are another thing in them selfs. Im sorry but how much re-search did you do none of this stuff is "drop in".

also a good read https://honda-tech.com/forums/all-motor-naturally-aspirated-44/degreeing-camshafts-quick-shakedown-2003538/

 

im sorry for all the stupidity :/ im building my brother b17 im used to mustangs thats why everything for my 5.0 is bolt on

 

There's to many kids who think you don't need to do any of this(takes to long/is to hard) and can just "throw them in". I don't know from V8's but most of this is applicable save from the degreing aspect being some what different.

 

i dont care how long it takes i just need to do everything right

 

another thing im having trouble understanfing the skunk 2 **** like what does it mean by duration @ .050" and where would i get that big wheel that i put on the crank i appriciate the help man i just want to do it right and do it good

 

where it says lift is that the hight point of the cam lift? and the next is at the degree the crank should be at but what does "durattion at .004 or .050 mean"

 

It's all in those 2 articles I posted for you. google "lift and durration explained". Also you might want to revise and then re-post this in the "all motor" fourm. if 98vtec or someone else with good know-how chimes in on you'r thred you'll get more help.

 

I'm not like 100% sure if this is right (I sort of just guessed it based off picturing all this crap in my head)

But duration at .050" lift means, starting at the point at which the valves are .05" open, around to where the valves are now closing, to a lift of .05" open, is the actual duration of the cam.

The advertised duration at .004" is the same thing, but starting and ending with the valves barely even cracked open (which is why the advertised is so much bigger than the lift at .05")

and yes, lift is the high point, meaning the maximum the cam will open the valves.

 

should I go with advertised or just duration

 

Advertised is always more realistic metric to use i believe, since until your valves are actually opened up a decent amount, they won't really flow a lot.

 

Thank u for all the help haha idk what I would do with out this website

 

The vtec lift seems a bit high. i know when i bought my stage 3 bc cams, when vtec engaged, the retainers made contact with the valve stem seals. I think the lift was about the same as that. id have to look at the card. also comp cams makes a really nice degree wheel set. i picked mine up 2 years ago for 100 bucks.

 

i locked vtec and i dont have any clearance issues with the retainers i dont think i have .0250 between intake valve and piston and .0270 inch beyween exhaust valve and piston with vtec it doesnt seem like it makes contact because the can doesnt catch up on anything

 

No I meant from the retainer to valve guide. With the seal being a bit squishy it may not bind the cam enough to notice. Just double check with the cam manufacturer if there's any special precaution to installing the cams.

 

All they are saying for the pro 2 cams is springs deeper valve pockets it said nothing about the retainers or anything along those lines
