Pyro Posted October 20, 2004 Share Posted October 20, 2004 Take it easy on the porting and polishing. It adds up quick and doesn't do much. How and where do you polish a piston? How are they planning to port the intake and exhaust manifold? Extrude honing is the only way to get in there with out cutting it open. Port matching is about the only thing they can do and it does not do much for performance, it just costs a lot. Rings and pins typically come with the new pistons. Use felpro gaskets and C77 bearings. Don't forget to ask for a valve job. I didn't see that on your list. Don't deck the block unless it needs it. With all this porting and polishing what cam/springs are you planning to use? You could pay for a balance job on the rotating assembly but I have never been convinced a L28 really needs it. However, I know people like to say their engine is balanced. I did a 1000.00 rebuild on my turbo engine and I run it hard every day making 15 psi of boost and hitting 6K rpms everytime I get in it. It hit 108mph in the 1/4 mile a few weeks ago and not one thing in the engine is polish or ported or balanced. I also used cast pistons and a felpro head gasket. I think you should take it easy on the engine polish and spend your money on something that will make a difference like a limited slip diff, or a aftermarket efi system, or a good clutch.

Guest ON3GO Posted October 20, 2004 Share Posted October 20, 2004 i have a HKS headgasket and yes its getting a 3 angle valve job its not getting crazy port work, and im doing the port work on the exhaust and intake mani. im getting all this work done for me for like CHEAP! mike Quote Link to comment Share on other sites More sharing options...
Confused Posted October 21, 2004 Share Posted October 21, 2004 Sounds like it will be running like champ, probably better than ever before. With all that stuff done, do you plan to keep the boost the same, tone it down, or turn it up a little? Quote Link to comment Share on other sites More sharing options...

Gollum Posted October 21, 2004 Share Posted October 21, 2004 the real quesion is where is the boost gonna be during break in? About 3 psi? I know people who are really particular about how the break an engine in. Quote Link to comment Share on other sites More sharing options...
Guest ON3GO Posted October 21, 2004 Share Posted October 21, 2004 will be stock so 5psi. mike Quote Link to comment Share on other sites More sharing options...
Guest 73Turbo240z Posted October 21, 2004 Share Posted October 21, 2004 mike you need to swing by my place and have a look at some of the port and polish work that cameron does, not to steal buisness from the machine shop since i plan on finding out everything you have done and what it cost since i'll be having to go that route too, however... as a friendly curtousy i'm sure i could get cam to port match everything and polish your connecting rods and crank for the cost of materials. I'm not familiar w/ the internals of the motor yet, so i'll ask, would knife-edging the crank and then rebalancing it be beneficial on these motors? reduce windage in the oil pan / rotating mass reduction / etc...

zcarnut Posted October 21, 2004 Share Posted October 21, 2004 How about: New oil pump? New timing gears and chain? New core plugs? New rod bolts? Honing the cylinder walls? On high mileage L-series engines it’s a good idea to replace the oil pump/distributor drive spindle and corresponding helix gear on crank.
