im planning on building another d14 head with springs, retainers, cam, 3 angle valve job, and a port

i am going to replace the valves in the head and was wondering if it is worth wile putting in 1mm oversize valves. obviously i will get the valve seats cut to suit. so is it worth it?

cheers

i think you can buy them from the states on ebay too. must check that again actually. so the parts i have listed is all i need? im keeping the d14 head as i have ported it and got a cam reground for it. gona get a 3 angle valve job done also. and sum springs. i want to change to the 240 injectors as...

well all. ive decided that im going to do my obd1 swap next. the car is a 97 UK civic. This means its obd2a right? which means for going obd1 ill need d16z6 injectors (240cc) d16z6 distributor d16z6 IACV p28 ecu chippd and a tune on chrome. also a obd2a to obd1 conversion harness. This is all i will...

the d14 one should fit if i remeber correctly. im still using the standard d14 cable. the only thing is its a bit longer than a d16 but still fits. i think...

Man thats very cool news, I wonder how different it is. I would like to use a Y8 head and these Z2 pistons on my mini-me to bump up compression even further. I will recommend you to use D13 pistons because their deck height is positive. It will give you more compression than Z2 pistons. 1.3mm skimm...

my engine shakes like hell at idle and sometimes nearly stalls. this is down to my bad cam timing at the minute. i still have to set it.

haynes manual also says that the maximum compression difference between each cylinder is 2bar so 0.5 aint too bad.

what did ur compression read in bar?

thanks for that. think im deffinatly gona go for springs anyway. prob will just get the titanium retainers too as they are only around £80 extra and im not completly sure what my cam specs are. not sure wether to get valves tho? s2 ones arent that expensive. need to get obd1 first and see where peak...

1.3mm skimmed of my head

i think the in between values for said valve clearances are 0.008 for inlet and 0.010 for exhaust. in inches. of the top of my head so dont quote me

does this mean that with the D14A4 head we can use d16 valves, springs and retainers?

Thinking of upgrading mine and going obd1 so can allow the engine to rev more instead of power still climbing until hits limiter.

cheers
