[almostJDM]

so i have the cams set at 15deg btdc or what ever they should be and having the timing correct altho now that i think of it it wont be that hard to get the crank and the cams set up lol

UPDATE

ok time to get this build officially under way hehehe
after taking a closer look at the combustion chambers i noticed that the area that had the dings in it was flat so i just took my dremel and a fine sand roll and buffed off the pieces that wer sticking up then used a super fine roll and made it smooth then used the roll on the other 3 to make em simaler

might look into those to raise compression back from the material you removed... plus if youre redoing the head like you are, it may be worth installing freshly cut valves and new valve seals...

i ordered the chrome set, waited a bit, then they told me they can only get the black nitride coated ones and they upgraded me for free


how do the cylinder walls look, get scarred at all?

[almostJDM]

yea but i dont think they will work with the f20b will they i thought the f20b valves had a sharper edge to em

edit: but if they dont then ill do that

oh and no the cylinder walls are perfect but i dont know about the bottom half or so since the pistons are still in the block i hope there ok or shoudl i say it since its just #4

[jhondayaaj]

I would take the pistons out and inspect them thoroughly. also the rod bearings. mine had slight scratches on the cyl. wall, and the bearings were showing detonation.

[almostJDM]

im hoping thats not the case if it is will i just be able to hone it if its not to bad? i can get new oem bearing for the f20 for $14 a piece

Skunk2 Pro valve springs
KMS Titanium Retainers

Contact KMS first before you order the retainers. When I had a set of KMS Springs and retainers they were not compatible with any other combo. KMS basically designs their own stuff to work with each other and none other. So make sure before you order.

[almostJDM]

ahhh good point lol i didnt think of that guess ill see if skunk2 makes retainers thanks

edit: lol they do

cool cool how much they runnin ya? for both the pistons and rings?

[almostJDM]

you guys think i should sell my cams, valve spring, retainers on ebay? or should i keep the cams? hmm i could turn em into some jdm inspired furniture altho i could make quite a bit off the parts

[jhondayaaj]

cool cool how much they runnin ya? for both the pistons and rings?

custom pistons and rings for 150. 30 bucks for the bearings.

[almostJDM]
