Valve clerance for 4age 16v

[Os7213]

Hi guys im looking to do a shimless conversion from 1SZFE to my 4age 16v red-top engine. Since the under-bucket shims is crazy expensive ill go for 1SZFE conversion.
I will use 272deg 9mm camshaft(int\ext) and im looking for valve clerance to use these camshafts.
I have a Toyota repair manual and it say the valve clerance should be:
Intake: 0.006in to 0.010in
Exhaust: 0.008in to 0.012in
But these clerance are for stock camshaft.

I got also a TRD Bible wich set the clerance for a 272deg 7.5mm lift to:
Intake: 0.005in
Exhaust: 0.007in

But i want to be sure of wich clerance I can use for my type of camshaft, someone know a clerance to be used for a 272deg 9mm lift camshaft(int\ext)?

Thank a lot

Ugo

you 'll have to find the installation sheet of your cams my friend ...

[delange]

only know is that they should be less than the 7.5 lift, but you probably knew that already

hope you find the right info

delange thats not true, I had 8.5mm lift on my exhaust cam and 9 mm lift on my intake.

I ment that the clearence schould be less, cause of the higher lift, correct me when I'm wrong

I have look carefully in the box, no paper at all about valve clerance.
These cams are Toda racing 272deg 9mm lift.
If i cant find the right valve clerance specs i think i will go for the N2 valves clerances specs and see what happen.

On my Web cams(294 grind)... I'm using stock specs...
cold
intake - .15mm to .25mm
exhast - .20mm to .30mm

I'm the overzealous type... so I made ALL intake clearances .2mm and all exhaust .25mm each is dead on in the middle of the spec

by matching all clearances..... in theory... all lifts/durations will then be identical when measured at the valve

[apardal]

Clearances are related to the material which the cam is made and not its lift or duration.

HKS states that for 256/264/272 camshafts the clearances are the following:

Intake 0.25mm +/- 0.03mm
Exhaust 0.30mm +/- 0.03mm

Toyota states something different that I can't find right now!

Best regards
