Which oil pump and timing compnents to buy?

[warpd]

So I am building the engine on my 2001 Cobra to go turbo Manley Pro I-beam rods, MMR Manley pistons etc. I am trying to save a little money if possible on the front timing components and oil pump. I am trying to make about 1000rwhp. What is the best oil pump setup to go with? Is the MMR pump worth it and/or necessary? What about the billet timing chain guides, tensioners etc.? I don't mind spending the money if I HAVE to I just don't want to spend hundreds of dollars on unnecessary snake oil.

The best bang-for-the-buck oil pump is the Shelby GT-500 version right from Ford. It has a steel backing plate and only costs about $75. After that, go to Boundary Engineering and buy their billet gears for just over $200 and install them yourself. You can pay $400+ for other pumps and gears, but you'll get the exact same thing here and save some $$$$.

Plenty of info on the pump, timing gears, and other necessary mods in this build thread at ModFords:

What about the billet timing chain guides, tensioners etc.?

The oil pump advice above is good. I spent $400 myself on a pump and then later realized I could have just purchased billet gears and installed them myself.

I've never seen a need for billet chain tensioners. Seems like bling more than anything. If you have the new style plastic primary tensioners with no ratchet setup toss them and get the earlier version cast metal ones with a ratchet. Not only are the stronger but they hold tension on the chains more consistently as the oil pressure fluctuates.

I was told the GT500 secondary chains are stronger than stock and don't snap. I put a set of those on because I have heavier aftermarket valve springs with more aggressive cams.

One thing I did invest in this department is the Cobra Engineering secondary tensioner adapter for the passenger's side head. It flips it around to be on the correct side of the chain. If you look at the other three tensioners on the entire chain setup they all tension the trailing or "slack" side of the chain. The exception is the passenger's side head which tensions the leading edge or pulling side and as a result as the tensioner flexes in and out it will be constantly changing the cam timing between the passenger's intake and exhaust cams. Not good at all.

That's all in my build thread...

I'm a fan of TSS pump gears.
I also have the cloyes adjustable cam gears. Some people seem to be on the fence about their chains
