without the turbo it idles at 30psi and wot at 60psi

 

Using a solid lifter in these motors also require adjusting the valves as maintenance item or are the solid cams super super hard and don't wear quickly? I'm not familiar to the type of OHC "follower" buckets these engines have so I have absolutely no experience with them.

 

something's whacked if your throttle is changing oil pressure independent of rpm

I'd go so far as to add "shim-under-bucket" solid lifters for revving to 10k. I'd be nervous revving the heavy over bucket shims to high revs for extended periods (higher gears)

Nice build Tom.

 

I wondered when you were going to post this up...

PM me if you are going to part with all the old stuff ;D (At least the mani/downpipe)...

 

to the op, im loving the manifold you are making

i have a quick question, what the difference between a 3 angle valve job, and a 5?
i just noticed u had a 5 done, and ive never heard of that

 

Better flow past the valves and better seal do to more contact points.

 

an ideal valve seat cut would be a smooth radius for flow but since that's virtually impossible to produce for cheap, shops will cut a series of angles to simulate the round edge. the more cuts, the closer the approximation is to a smooth curve.

 

My head has the shim under bucket conversion as well, but it's actually the theoretical risk of water pump cavitation (as well as general engine longevity) that has me keeping the redline <9k rpm. Not too many people have been there so hard to say if it's an issue or not, but it'd suck to kill the engine over 500 more rpm when 8500 seems like plenty, especially when the torque starts dropping off after 5-6k based on dyno charts.

 

Electric water pump! You could even set it to run a min after shutoff to keep the turbo cool, like the new TT BMW's.

 

well let's see if Brian did a good job choosing cams before you say that

 

i see, more cuts = smoother, got it

 

 

very nice mani. i like it very much

 

Step #1 DONE! Only a zillion more to go!
