this **** is starting to get annoying

 

OP should look into the sweet azz turbo rotary with pistons upgrade. Mustang GTR style..pretty rare

 

Man, you guys are ******* ********.

OP, here is what you do:

First off, you are dead on about getting a block with low mileage. By 100K cast iron is significanly weaker due to the sheer number of heat cycles it has been through REGARDLESS of the differences between highway miles and stop and go traffic. Beyond the simple strength of a new block, it will flex less, meaning you are going to have a much more consistent tune. Honestly, I would get a new block from the factory. They are still available if you contact the right dealer.

Next, ditch the stock rods. Forged pistons will not only handle the boost better, they will also be lighter, meaning you can rev faster.

For an ECU, you should skip all the lame stuff like MegaSquirt and go strait for a MOTEC setup. More expensive and more complex maybe, but if you want to do this right, its the way to go.

T3 turbos are pretty much old news. While T3/T4s can definitely work, personal opinion is that you need a S500 series turbo to run that kind of boost consitently. Old Garret stuff is too sensitive to the ambient temp and other factors.

Finnally, what trans will you use? Thats where you will need to really do your homework on this. Some people swear by the 6 speeds, particularly later year MS units, but IMHO something along the lines of a w58 trans from a Toyo is going to be more reliable.

Keep in mind that people get all hung-up on power levels online. Ask anyone on the street actually doing some real-deal highway roll-on racing and they will tell you that a 500HP high boost car can take a car making slightly more power but a bit less boost simply because the higher boost car make more TQ. TQ matters, not some dyno plot that only measures HP.

I dont blame you for not staying on this forum. Frankly most of the really helpful, knowledgeable people are over on the Club Roadster forums and Miata.net.

Good Luck!

 

piston rotary

 

Someone has been watching the LeMons forums

 

nah, thats a radial piston engine in that mr2. But yes I do like that mr2 build.

 

Sorry I actually dont know what ive done to **** you off here...?

LOL not you dude. I was saying that the mods ******* with my sig is getting annoying. (they keep changing it lol)

 

Sweet, i was thinking, I respect this guy here, and give props to his sig, now hes pissed off with me.. Aren't I ranting to noobs about their flaming homosexuality around here enough? I know I dont fit in when I tell noobs to shut up and listen rather than just tell them to run a 500 shot.. lol

Cheers mate,
Dann

 

sounds like a good time

 

Wow... this is totally wrong. Low miles will certainly have less corrosion in the water jacket, but did you cite that issue, nope. You went with heat stress. If your engine is getting hot enough to cause atomic creep in cast iron, you have serious issues. An engine should never, ever get that hot. So basically, the strength of an old block, corrosion argument aside, will be the same as a new block. And in some cases will actually be stronger due to nitrogen in the combustion chambers being absorbed into the cylinder jackets on an atomic scale.


Yes power levels do matter, way more than pressure levels. More boost doesn't make more torque. It actually makes less, more boost means more heat. I don't care how amazingly awesome your intercooler is, higher initial temperature means higher cylinder temperature. And I don't know what dyno you go to that doesn't measure torque, because that one is physically impossible. You can't just measure 'Power'. The HP is calculated by measuring the torque and then deriving the power from that measurement.

 

Did you seriously not catch his sarcasm?

 

Apparently not. I am discovering that posting before coffee is just as dangerous as drunk posting. Meh, wouldn't be th first I've put my foot in mouth on the interwebz.

 

radial engines works a "bit" differently otherwise you got unhappy passengers on the plane

 

Well after i saw this i had to post it here...

 

Tee hee! The kid that is building his car around a target PSI called me a ricer! how cute! Well, you still live in KC and I left, so I guess that makes you right, KC is all ricer.

I was under the impression that fighter jets that say US NAVY across the side were not rice, but I guess I was wrong. Hey can you teach me to run 20psi too? My old rx-7 only ran 14, granted it broke the tires loose in 3rd gear, but boost is what matters amirite?

 

yeah radial engines have a moving crankshaft
Rotary pistons have a stationary crankshaft and have their cylinders move around them.

 

The other rotary engines:

 

This is a disgusting post...has no business in any miata forum..should have been deleted....and I cant believe the op took the time to answer with this supposedly funny garbage?

 

If you want something worse I can give it to you. If you don't like it, don't read it. This is the only way I can climax, deal with it.
