FM sells inconel valves now. My engine was done before they became available, so I have no experience with them. I assume they're quality pieces and they're a lot less expensive than previously discussed.

The Corvette only uses Titanium valves on the intake, and sodium filled valves on the exhaust.

Titanium isn't a good material for the high temps of an exhaust valve. Since intake valves are larger in size than exhaust valves, Titanium is used to reduce the mass of the intake valve.

Supertech has Inconel +1 exhaust valves on the shelf for the BP. We can get them for $27/valve ($216/set of 8). If you're doing +1 valves in a forced induction head, it's a no-brainer upgrade.

It's funny, when this topic first came up 2 years it was such a radical idea, the guy was hassled for a page saying it was a waste of money, spend his money elsewhere, don't waste your time. And now it is "no brainer" upgrade for +1 BP engines.

They weren't 216/set.

xceldyne makes titanium valves, thats all they make you could get custom ones made pretty fast i bet. They sell them with nice TIN coatings too. You will need to install beryllium copper valve seats to run titanium valves reliably. Good luck

Precisely. I'm still waiting to pull my engine to pull the head and get it machined, but they were a pretty good deal, around a grand for springs, valves and a SuB setup.

Two years ago, you couldn't get them off the shelf. Today, it's an $80 upgrade over a standard set of +1 backcut SS valves. Forgive me for making progress in bringing high-end parts to the community at reasonable prices. :jerkit:

The cost is not relevant for the point I am making.

That's fantastic that you bring high end parts to our community for reasonable costs. How about a set for a 1.6?

I was just reading the thread, the guy wasn't concerned with the $$$ side of things he just wanted to know where he could have them made or where to buy them. Then a page of "you don't need them, spend your money elsewhere, why, etc" It just amuses me that once someone thinks outside of the box, everyone jumps their shit.

I'm not starting a debate or a pissing contest.

Cost vs Gain was exactly why people were convincing him its unnecessary.

You can make all the points you want, but when someone tries to stuff $1000 valves into a 20 year old engine that, on its best day, won't even touch the more modern and better designed/developed engines, I'm gonna tell em its probably silly.

On the other hand, if you can get baller new/cool parts for a very small premium over inferior/older parts, you bet we'll tell you its a good idea.

Does that make sense?

If it doesn't, give up.

I see this all the time on this forum, majority on here own miatas cause they are cheap and can be fast. Its not the reason i own mine, and some of us like to burn money for the hell of it, you can always make more.

You understand my point. Your car is 100% badass, and I am sure there have been a lot of things you have done that was outside of the "norm" and people asked you countless times why you did what you did, or you should have done it this way and not the way you're doing it. It's like me building a 1.6, sure, to most it is a waste of money. But I want to build it because I want to see what kind of power I can make out of it. The same reason I have a spare head to blow a bunch of money on doing port and polish, cams, big valves, springs etc etc. Not because I look at it as a 20 year old relic (which it is) but I look at it as a learning experience. Porting my own head, clearancing the lifter bores myself, and all the stuff that goes along with that.

dude

lol

If that's your objective, to blow a ton of money in order to learn a thing or two, by all means. I have no argument against that.

What I learned at an early age though is that its so much easier and cheaper to learn from others' mistakes. Also much "free" advice from reputable/smart people has managed to save me thousands of dollars over the years, and I still had a ton of very fun cars and don't regret anything.

I'm nothing against your train of thought, you met me and know how I am. I just prefer to do things differently. I leave the costly mistakes I make for the times where I cant gain the knowledge for free/cheap.

To be able to "go outside the box" usually means spending a TON of money, and is very rarely worth it. I save that kinda stuff for people that don't care about their money or have so much of it that they just don't care either way. I believe many of the "regulars" here are similar minded (at least in this specific topic) and therefore question threads like this.

I think you're a bit bitter at people hating on the 1.6 and try to start arguments that really don't matter.
you won't change the miata world/community and they will always be cheap and thrifty.
