Is it hard to change Valves? I was wondering if I can just keep the engine at TDC just lift the head up and using a valve spring compressor, just remove the valves and change them over one at a time and just put the head back on. Would that be fine to do? or is there something more complicated involved?

I'm going to switch over to high compression valves. Also is it a good idea to change the piston rings when I have the head off as well?

 

If you're pulling the head off, why not just pull the oil pan off, and put in high compression pistons instead? It would actually be a lot less work.

High compression valves? How does that help airflow?

 

high compression valves.....

 

Valves are cheaper... they improve airflow by having the cutback and having tapered stems allowing more air into the engine. I'd get horsepower all across the RPMs, without sacrifing any. It will help my lower end power and torque, which I can use a bit of to launch harder off the line.

I want to go turbo in the future, probably like 6-8 months from now or sooner if someone hands me some money or something so i can get my edelbrock turbo kit. lol... I'd run a thicker head gasket or just get low compression pistons when I go boost, I dont need high compression and boost or bang. I'm aiming for around 9:1 compression ratio with boost. Too much high compression would spool a turbo too hard, and if it spikes or creeps my engine is gone. Then I get a B18C1.

Those valves increase compression ratio .3-.5pts so that could be from 9.9:1 or 10.1:1 compression for me.

 

I think you are on crack

 

agreed, only someone whos thoughts are clouded by drugs would spend the money there asking for that edelbrock turbo kit :chuckles:

 

What do you mean? It's the only complete kit on the market for the D16y8.

 

valves don't increase combustion. Pistons, rods, crankshafts, cylinder heads increase combustion. If you are going to go with a thicker head gasket, please get a longer timing belt. I'm sure you can get the belt to squeeze onto the cam gear, but the belt will have a lot more strain on it and could possible skip a tooth or even worse, break.(not cool) If you are talking about cams, those will give you more horsepower, but not compression. Even if you do get cams, there is still a lot you need to do to get the most out of them. Cams change the time your valves are open and the time they close. I'd defenitely do some research on timing and proper valves and plugs because if you do the setup wrong, you are just going to burn the craep out of your valves and eventually destroy your engine. good luck.

If you are going to go turbo, i'd get your head port and polished. That will give you a lot more power and reliability then just valves. Valves are usually changed to help with reliability and strength, not horsepower. Just changing valves without port and polishing isn't going to do much.

 

Hold on a minute here. Reality check.




You have a d16. Valves... aren't going to do you any good whatsoever. You could improve your car's performance more by taking a big shit before driving.

 

as usual you sum things up so much more eloquently than I ever could.
