Custom 5SFE Intake Manifold Project Options

[Bitter]

The mouths look awfully flat.

[doory100]

I made them myself. I think there pretty good and they will be better than a straight pipe.

[Bitter]

Yes, just the transition from bell to pipe is pretty sharp, which the point of the mouth is to smooth that out. You can make them a little bigger and just notch them where they run into each other or vary the heights slightly.

I'm at the point where I really just need to get this finished. I'm sure it's not going to make a massive difference.

[Bitter]

Cool, there's always V2, V3, etc to get things perfect. I'll be excited to see the outcome and results! It's always interesting to see these projects, don't take my criticisms as all negative. I'm just trying to lend a little advice from what I know so that the project has a more favorable outcome and maybe inspires more creativity with these cars. Even though I don't own one, it doesn't mean I don't like them. I'd have a V6 GT in my garage if I had the spare money and garage space. One guy who already has two cars though....

Just got my cams back from delta camshaft. They look OK. I've never had cams reground before. Is it normal for the cams to look like they do?

[Bitter]

What is it you're worried about with the cams?

[doory100]

The lobes. Is it OK for the them to have chips at the sides and bottoms of the hard welds? Or is that normal in a regrinded cam?

[Bitter]

Are the followers going to make contact with any sharp edges? If they're not then it should be fine.

[doory100]

Followers? I'm sure they know what there doing at delta camshaft. It will be fine.

[Bitter]

Shims, whatever makes contact with the lobes (follows the lobes). You can always ask Smaay, he'd know.

What lubricant should I use to break in my cams? I was going to get new springs and valves. Should I spend the money or use my old springs and valves? I might just replace the exhaust valves, mine are pretty dirty.

Intake valve

Head is off the car right? Pull the exhaust valves and clean them up on a wire wheel then check them.

[doory100]

bought new valves for $100 CAD for all 16 of them!! I would have saved them if they cost more.
here is a picture of the ports and head all polished up and I also painted the front and two sides to match the valve cover. I also painted the V6 Camry TB red(its in the background).
The ports look rough but there not clean in the picture. I also lapped the valves but im having a hard time putting the springs back in. Any thoughts on that?

You should at least check them for straightness and size, which requires a special tool set which probably costs more than the guides do.

Yes, I'd replace them if you're replacing the valves and seals and the head is off. You're also going to need to re-shim all the lifters to spec too, that's a fun process. You might want to PM Smaay about clearance specs, my understanding is you want them at the loose end of the spec so they don't get too tight when the engine is hot.

[doory100]

nah I think there ok Ill let that one slide. Im putting in all new lifters. do i still need to shim them. I thought you just have to tighten the lash?

new valves will have new clearances and need to be adjusted, as will new lifters. some stems may need to be ground as well.
