Not sure if this is the right thread but theres some good info about the valvetrain there anyway. http://www.mr2oc.com/showthread.php?t=4 ... ics/440599


Amazing you were doing this well with bent valves all along...


I already looked up the specs of about every valve spring for the 3S-GTE. The problem I found is that some companies have about the same pressure as the GSC Beehive I'm getting but with the bigger (standard size) retainer they are not meant for the rpm I am turning. All the companies were claiming that they are only good to the 8000-8500rpm and like 35psi. GSC is the only company that had a spring/retainer setup that was designed to handle 9000-9500rpm, 40-45psi of boost, with a 272 10.4mm lift cam. Below are the specs of all the valve springs I found. If the companies website didn't list their spec I emailed them for it. Only the Engle one I got from the exact forum thread you linked but I had read that and got the info on them before.

Machine shop just tested one of my new springs.

@ 1.354" or seat pressure is 90lbs

@ .954" or 10.15mm of lift is 220lbs

They said when they break in they may come down as much as 5 lbs of tension. But still this is a big jump vs the Ferrea set I had before.

Stopped by the machine shop today. I found out they had to machine the ID on the spring seat area to fit the GSC beehive springs. They have that all done. They also already installed all my new exhaust valve guides. They were starting on my valve seats to repair them but it was cutting like crap. Then the guy noticed that he was to bare aluminum in one. They looked closely and it seems Toyota has a coating or spray on material for the valve seats vs press in ones and mine is all gone. They have never seen anything like it before. So they are now changing them to press in ones like the video below.

It was fun watching the video of the machine cutting that seat. That was my job (except on ls motors) when I worked at Texas speed and performance. I would knock in the new seats, do the valve job, blend the heads, and reassemble.

Thanks for bringing back memories ha.

Finally got the car all back together with the new valve train and .051" (1.3mm) head gasket. The thicker head gasket brings my compression down to 9.7. With the thicker head gasket my cam gears had to be moved to retarded 2 degrees for both intake and exhaust for the cams to be at HKS spec.

Here is a video of it running at idle:

Here is a video of me free revving it (it was raining so I felt I needed to have some fun):

Hey Ryan reading back you plastigauged your mains to 0.002"-0.003" oil clearance.
Couple questions. Are the rods and crank mains about the same clearance?
Did you notice a drop in base oil pressure? As stock are 0.0009" to 0.0017" from memory.
About to set my motor up and deciding on main clearances

FWIW.. I'm running 0.025mm (0.001”) extra clearance on both rods and mains without a drop in oil press (un-shimmed camry pump with 3s gear). Ryan's running looser specs based on what he's doing, but also has more pump as a result.
