Mothra SR20DE Swap in Florida

Where are you in NE Florida? There are a few of us up here

Saint Augustine!

I know that you are, the question was for kronista

Ha! I guess this is the end of this foolishness...

I have been looking to replace a lost spark plug wire and was given a site to look at by Michael Spreadbury. I was thinking before I ordered the wires maybe I should see if had options. Anyone purchase spark plug wires for their SR20DE S14 engine that you could share the name with me?

[Bigtaku]

No answers on the spark plug wires so off to the next question. I will be putting in new brake lines. Has anyone ever used stainless braided for the hole line? It seems that it would be much easier to use/secure/bend a braided line. Thoughts on my options please.

Hi Michael
In response to the brake line question. Do NOT use braided flexible lines for brake system. As an ex-hydraulic engineer I can say that it’s a bad idea. The flex lines allow for expansion and brake line movement which will reduce the pressure in the line, as it will be exerted on the expansion of the line, in turn reducing the amount of force exerted on the caliper (or drum brake piston) and therefore reducing braking power. This is not good. Yes some flex line are needed in areas where there is movement of steering or suspension but those lines should be as short as possible to reduce any pressure loss.

Hope this helps

Thank you Matthew. It looks like I'm going to get good at bending stainless then... I have the old lines still which should help with some of the bends.

All my welded frame brake/wire clamps were rusted badly so I had them removed. Now with a perfect rust free painted frame I need to add clamps. My plan is to use self tapping screws with blue locktite and clips from McMaster Carr. https://www.mcmaster.com/#p-clips/=zyrbu8
I really do not like the idea of drilling into the frame because of possible rust issues down the road or the chance for the screws to get loose but it's a little late to weld on clamps. The car most likely will only get wet when I'm giving it a bath anyway.

I would not go with Stainless as it is a real pain to bend. I plan on going with NiCu; have already bought some from this guy. In fact, I'm planning on using for my fuel line too unless I find it can't work. This stuff is super easy to bend, and won't rust either.

See these folks for quality line.

If you are keeping the stock plumbing, look at classic tube. They make new lines

I second this. It’s what I’m using. Though I would not suggest using for a high mileage daily drivers. I can suffer from fatigue. But for a weekend driver it’s perfectly fine.

When you say it can suffer from fatigue, are you saying that stainless is a better choice if I don't mind the headache of bending it? I haven't taken any short cuts yet and want the best I can get. I want the ability to drive as much as I want to and not worry.

If you want to go stainless, I would just go with Classic Tube solution, Pre-bent and ready to go. Cu-Ni is perfectly fine and much easier to work with if you are bending your own.

So in your opinion Cu-Ni will not fatigue enough to worry about? With my custom brakes and master cylinders I think I will need to bend my own.

[notoptoy]

In my opinion, no problem at all, Cu-Ni is widely used and proven.

[Mattk]

Cu-Ni will be just fine.
