And you also forgot to add the Flux Capacitor for that extra time decrease.

Few things

First, I forgot some VERY basic things - remove the exhaust (or if you wanna keep it on the street AND legal, get a catco high flow cat, weld it to 3" pipe, cut a section of the pipe and weld in a summit racing muffler, have another pipe, and another muffler at the end - it'll be quiet and flow great!), remove the rear seats, remove the navigation, turn DSC all the way off (hold for 8 seconds), replace the hood with vented carbon fiber, replace the front bumper with a large-mouth carbon fiber piece.

As far as the GReddy turbo, I've ripped on it enough - basically its an 18g compressor inside of a TD06 housing (that's the big one, for you guys that aren't up to date on Mitsubishi turbocharger hardware).

Sure, its good for 20 psi. Is a 10:1 compression ratio engine? No way in hell. PLUS, the GReddy turbo at 20 psi makes 400 hp - my GT3540R on my RX-7 made over 300 at 10 psi - it was good for 700 hp.

Since we want to keep the psi low, we'll definately need a bigger COMPRESSOR, but, because we're hamstrung with a Mitsubishi manifold already, we'll have to just use a more advanced, slightly larger one - like the FP3065. What you get is a TD06 housing (same size as the GReddy) with a GT42R compressor wheel, dual ball bearings for fast fast spoolup, superhigh tech, something like 3 times as many blades pushing air - its just far far better technology.

Let me make an analogy - Mitsubishi 18g = Tapedeck, Garret GTxxR series turbos = mp3 player.

I made a thread where I compared compressor maps, showing how the GT42R flowed almost twice as much air as the 18g. Anyways, point being, it'll fit.

As far as the wastegate, they can be moved/closed/controlled. Regardless, the wastegate isn't going to be a huge limiting factor here, I just prefer external because it usually takes care of boost creep.

The real key here is going to be using a good, strong boost controller and tuning more than just fuel. You're going to want to get a GReddy electronic boost gauge and attach it to the e-manage so that the e-manage no longer reads throttle and rpm position and instead reads boost levels - this will get rid of that spike in boost that you guys are getting because fuel will be added at appropriate levels to boost. Will the injector and ignition harness you can get 16x16 map access to control injector duty and ignition timing - these are gonna be key when turning up the boost.

LOL MMMM Z06.....good thing to know that other turbos will fit.....i don't know much about mitsubishi turbo's. so you can get the greddy and up grade later when people get the kinks out o ffi on the 8. good info Cretinx :D

LP= Low Power..

European version with 192 hp and slightly more torque than the High power version.(220 Nm vs. 211 Nm)5-speed manual gearbox.Revs to about 8000..
I've got the Revolution-model which includes 18",big brakes,power seats,Bose,heated seats,DSC and leather.. (Extras is different in different countries.)

Basically, Mitsubishi has a few turbos we should know about, they're all flanged the same, the difference is the compressor and housing.

The 14b was on the early Eclipse turbo, it didn't spool as fast as the later ones, but had a lot more potential. This is a TD05 housing.

The t25 was a Garrett clone on the later Eclipse turbos - lots of low end power and fast response but nothing up top. This was also a TD05 housing.

The most common swap is the 16g for either the t25 or the 14b. This had a TD05 housing. A lot of them are clipped/ported/polished and there are other variations with larger compressor wheels. I'm PRETTY sure this is the turbo on the EVO. I know I ran an EVO III 16g on my Eclipse. Again, TD05 housing.

The 18g was a bigger, badder 16g with more lag. This was in a TD05 housing. The GReddy turbo for our car is the 18g inside a TD06 housing. Don't worry about spool time on our cars though - there's a lot more heat generated by a rotary than a dinky 4-banger - rotaries spool their turbos about 3 times faster than a 4 cylinder engine, which is why the rotary and the turbo have become inseparable.

Finally, the 20g was the granddaddy - this was a bigass turbo that was in the TD06 housing - lotsa lag but the ultimate in Mitsubishi turbos.


And then . . . . aftermarket shops got sick of this ancient technology and started putting Garrett compressors in the Mitsubishi housings with Mitsubishi flanges, so they wouldn't have to go through the expense of a new manifold. You got your Forced Performance Greens and Reds which were the king of the hill for a while, but the newest thing is using the Garrett dual-ball bearing setups with the GTxxR series compressors - these are some nasty turbos that spool up ultra fast and blow twice as much air as their predecessors.


So basically, those are the options we have to choose from.

I'd probably suggest an FP Green or Red just because the dual ball bearings will spool up too fast on a rotary and kill traction (they're great for AWD Mitsubishis though!) - I had a dual ball bearing on my RX-7 and it basically liquified the tires through 4th gear, and hit full boost by 3000 rpm.

crazy naked man

Racing in a Neon is kinda like racing in the Special Olympics: sure you might win, but you're still a retard!

rx8pilot

dude..think about the **** you say before you say it.. just because it's funny to you..doesn't mean that someone here with a special sibling isn't about to find out where you live and kick the ever-living **** out of you....

"it's better to be thought an idiot than to speak up and prove it"

Hmmm...when I spoke with him, he told me flat-out the Renesis isn't going to be good for boost, period...and it's best to look elsewhere for power.

dmp

oh...and...


200whp...slicks...and weight redux = 12 second e/t's.

Come on, Dan, you know I mean no offense to and have nothing but great respect for truly "special" people and their families.
I use the term loosely because it makes a funny analogy. Since when did it become taboo to use the term "retard" to refer to a "normal" person in a disparaging way? Take the line for what it's worth and don't make more out of it than it is, and that is a slam on people driving stupid souped-up Neons.
End of discussion on that matter, BACK TO THE TURBOS!

Naked man, I hope you don't run in the nude. Because anyone running in the special olimpics has more internal fortitude then you could muster in a lifetime. We don't think highly of this sort of thing here. This is a group of adults who respect each and every life. More empathy should be extended to those who are strong enough to look past their limitations and enter an athletic event.
Those people must try harder then you baddest NFL hero.
Please have some soul.

crazy naked man

I thought I covered it by saying I have only respect for those people (the "special" ones, not the Neon drivers).
Would it be better if I referred to midget sports instead of Special Olympics, or will I offend little people on the site?

Or instead, I hereby issue a blanket retraction for anything I have ever said to anyone that could have in any way been percieved as offensive, crude, politically incorrect, off-color, in poor taste or just plain mean. My apologies to the world and all its inhabitants, because I'm sure to have offended them all at one time or another (including myself).

P.S. The above applies with an exception for people who drive riced-up Neons

burnoutking999

humor is not very clearcut. Its all in the way that you mean it. I have a relative that is mentally handicapped as well as I have taught ese kids with church and other functions for the community. I am in no way advocating the comment but i found it for what it was, a hilarious bash agianst neons. so all who claim to be open minded and accepting of "This group of adults who respect each and every life", practice what you preach and dont jump on people for making a JOKE.

Did he give reasons why the Renesis is not good for boost?

I've heard two stories now from Atkins. I called and talked to Dan, the son, and he said the Velocity Red is Un-Boosted now. I wonder what happened???

Racing Beat said in their RXTuner interview: "For those who are interested, we are investigating supercharged/turbocharged applications. However, we are a still a long way from deciding which method of boosting the engine is best for the RX8. As you can see, we have only begun to understand this extraordinary car. The RX-8 certainly has much more to tell us. Rest assured that we will be listening intently to what it says!"

You have a hummer that can do an 8 sec 1/4 mile? YEAH RIGHT.

Butch Brown

Just leave earlier so you can be on time with a 20 second quarter.

radarguy

I took the 8 seconds as refering to the 0 to 60 time - Which is a bit more believable than the alternative. My 3/4 ton suburban weighs in at about 3200 kg (according to the dump gal at the land fill weigh scale) Can you imagine how much hp is required to get that much weight propelled for a decent quarter mile time? http://www.turbofast.com.au/Drag.html
says I need around 2700 hp to get the 8 seconds.

Soooo...

If money isn't an issues and we want to keep the pride of the car going here, why not recommend a Cosmo 20b swap with so giant turbo on there. I feel like a large turbo is easily utilized on a rotary.

That shouldn't be too hard to hit under 12.5 seconds on the quarter mile, maybe? Beware of cost and drivetrain issues.

I am curious about why everyone is so concerned over drag times and not over track times... I find it much harder to be gusty in the corners. Just my 2 cents though.

8 year bump!

I'm not thinking you will get an answer any time soon.
