Titanium parts list!!! Time to rock.

[Mirage2LTurbo]

Crower springs and Ti retainers - $275
Crower Ti Valves - $1442
Crower Ti Rods - $1860
Crower Stroker Kit - $3300 (no rods)
Crower Cams - $570

This includes steel wrist pins, crank, pistons, etc. You're still going to pay a machine shop to assemble your engine, as well as balance everything and machine your block. You are obviously new to this, and think you're going to impress us by building a Ti motor. We really don't care, and after you build it, you're still going to be slow because you can't drive.

The one thing I might be curious about would be titanium springs. I have heard of their existence and googling it revealed this:

http://www.titaniuminfogroup.co.uk/automotive.htm

Uniquely among engineering alloys, titanium possesses the strength, density and modulus to make the 'ideal' spring for almost every application. The key to successful spring design is to optimise the saving of weight and space. Correctly designed titanium springs can be typically three quarters the height and 60 - 70% lighter than steel equivalents. The aerospace industry has long used titanium alloy springs in a wide range of applications.

Creating a spring that 60% lighter and 25% stiffer would make valves very happy...and the material costs would make it feasible, although it may take special machinery to coil titanium, in which case costs would be insane.

As for your titanium crank/pistons/head crap....I want to lob a hand grenade into your living room on Christmas morning.

There are some companies out there that are making Titanium valve springs , but as far as I can tell it looks like for us it would be a one off manufacturer item. Meaning no off the shelf products.

 

[TD05HTalon]

for reference Mugen, Spoon, Nismo and other racing companies and teams use Titanium rods and other titanium internal parts. Of course these are used in the JGTC endurance races. Some rally teams use titanium turbo parts like compressor wheels and ceramic turbine wheels. just because titanium parts aren't made off the shelf for DSM's doesn't mean other race teams don't use them in different applications and cars. open your minds up. most of us could never afford engine's like those anyways - for example a top fuel dragster's engine can easily cost over 100 grand.

 

[autronicDSM]

You got it all wrong. Our minds are open, that's why everybody says it's pointless. Race teams have a reason to use those parts. This guy doesn't.

 

[LandoAWD]

Guys, keep the debate going, but lets not "lob handgrenades" or "5 fingers vs face" the guy. Damn.

 

[L2RTSiAWD]

Ok listen up. either you help this guy or you don't post in this thread.

There is a difference between educating someone and breaking the rules by insulting/name calling or stupid crap like "I want to lob a hand grenade into your living room on Christmas morning."

Let's tone it down a bit.

The rest of that post was pretty good, and you have to admit it's amusing.

I never mentioned titanium crank or pistons or head . Who was this remark made twords ? I hope to God it wasnt to me .

Whoops, apologies sir. I got you confused with others.

TD05HTalon,

Just a note. Take a look at other post on here where I am providing info for burldude to compile.

Geeezzzz I get it from both sides around here...... :laugh: I just was unable to find any Ti springs for the 4g63 online at this time. There's lots of post from threads on other sites etc. where people are listing that they have Ti springs on their 4g63's but no hard facts as to where they might be coming from. I'm afraid they'res a good chance those are most likely bogus.

 

[burldude]

That is the same thing I have been running into . Iam going to look into v-8 spring suppliers . I did a build up a couple years ago and I think I can still find all the info .

 

[terefic181]

There are 2 companies in particular that kept showing up as making custom Ti springs. One was LSM Systems Engineering and the other I don't remember the name but I think they looked to be a more pomising. I'll try and see if I can find them again.

Here is one that specializes in custom ti valve springs . Havent got a price from them yet.

I just remembered Comp cams makes them to .

 

[autronicDSM]

LSM Engineering is a local place to me. I've heard they're super smart guys and do a very good quality custom stuff. Very expensive too.

 

[terefic181]

Here is some interesting reading regarding custom manufacturing Ti valve springs........

There ya go Burlude,

It was adding a second "HTTP" that doesn't show up when I post it for some reason, it's fixed so the link works now, but the site is undergoing renovation now it looks like. Sorry

Wow, this topic has careened all over the place, but I think the post about F1 engines and the post about Ti's relative properties vs. steel both went to the core of the problem: It's not the material that limits "conventional" technology engines. A lot of wisdom in those posts...that in our own circles is borne out impressively by the Shep's of the world.

Think about it: A largely stock production block, head, and valvetrain making what, 800hp out of 2.0 liters? Let's get this back into perspective.

So you want to go nuts with an exotic material and gain real performance enhancements? Take a billet of Ti and, as the man said, make a new head. In fact, make a rotary valve head and open up an entire new horizon of performance for the DSM 2.0:

This technology is perhaps the most impressive leap from the traditional valvetrain engine ever. Take a look at the technical section and then consider what a SOTA steel bottom end and one of these could allow you to do...

Oh no I know I dont have enough money for this . This is just to good to be true . Everyone can pm and send me a dollar and I will try to match teh money sent and have them make one . Time to sell the house and property

evo 8 uses a titanium compressor wheel, its blades are half the thickness of standard steel wheels so its lighter and spools quicker as well

I understand that they are the same size wheel is this true? When I say this I mean that it is a swapable part with the 16g evo ? I doubt that it is a swap though or there would be more post on this . Anyone care to elaborate?

Thanks for the headsup info

Check out www.ForcedPerformance.net The Ti turbo is on the front page. Unfortunately since it fits the EVO IV and newer the turbo spins backwards in relation to our turbos, so it won't work unless you convert you intake and exhaust to accomodate it.

Loreak, you were close, but the Ti turbo came on the EVO 6.5, not the EVO8. Also compressor wheels are made of aluminum, turbine wheels are made of steel, Ti, or inconel. I wonder how magnesium (Mg) or berylium (Be) would hold up as a compressor wheel? Time for me to visit Matweb.com again!
