RarestRX that is ill!

NA myself, I want both... still waiting for that 6000 dollar check......hmmm

 

My main problem with turbo vehicles is the dreaded over boost, detonation, turbo and apex seal destruction problem. I'm a paranoid guy and love beating on my car, so I don't want to always have to worry about that. Plus, turbo cars have a greater amount of complexity that can lead to problems that can require a lot of time and money. There's more parts to buy because once you buy one part it needs another to work property and reliably; it becomes a slippery slope of purchases. Sure you can just get exhaust and filter for a turbo car, but how long is the engine going to last with that kind of setup...ask the FD guys.

The answer to all the problems is the Renesis 13B. The Rennie will give us NA guys plenty of power, probably 300hp with exhaust and filter, and provide better gas mileage and reliability than past NA 13Bs. Rotors will be lighter, flow will be superior, overlap will be reduced, and hopefully we can kiss the pulsation damper and flooding problems good-bye. I can't think of a cooler daily driver than a TurboII car with the turbo engine substituted with a modded Renesis motor; it'd be like a GTUs on crack and having your cake and eating it too!

TurboII with a Renesis is the answer. Now just have to figure out a way of finding a Renesis...

 

I have both N/A and turbo and quite frankly I love them both, especially because they have rotaries.

The N/A is good for commuting in traffic/auto-x/no lagging. Once they get going and are in the powerband, it is beautiful.

The turbo is another beast with boost, which makes me drive way more agressive, it is evil like Kev said

 

Yo,


Mr. Wankel, you've come up with my dream scenario...I need to stick a Renesis in my GTUs. I offered up my car as a test mule to Mazda for the Renesis, but they didn't bite. *grin*

I'm with you 100% on the lightly modded Renesis idea, every rotorhead I know is like, "Mazda better have Renesis crate motors!" so all your Mazda USA lurkers on this board...

WE WANT RENESIS CRATE MOTORS!

*grin*

I'd get another GTUs sticker, cut the little "s" off and put it on my new Renesis powered GTUs. It'd be a GTUss...

KS
1989 GTUs "Gonna spin that Renesis to 11,000rpm..."

 

I have seen quite a few "fast" N/As... then i saw an FD. On that note, im selling my car. haha. my car seems too nice for me to want to rip up and make it a "quick" N/A. only 67K on the clock and near perfect condition, i decided i want to get a TII and rip it up instead. Rinesis is some nice ****, timmah!

 

Yikes!!!!.....

I love my N/A. But I also want a TII. Problem is, everyone is hoarding them!!

Rat

 

I just found another decent deal on an 86 NA olive green factory paint ?? No sunroof, base ****, for around 2k has a rebuilt motor and 120k. Body clean as hell.

Being the crackhead I am, I'm actually thinking about buying it so I can have two N/A's autox killers...hrmmm...

There's a TII thats been sitting for 2 years w/ only 82k that I could swap over everything....How cool would it be to have the only sunroof-less turbo II!! *dreaming*

 

VERY well said, my feelings exactly

 

I have nothing against the TII, nothing against the NA. Arguing over them is stupid.

Nothing more to say really. One car is not superior to another just because it is faster.

 

i just got the same wonderful idea that Rarest got. put a modded renesis in my 90 GTUs with that 4.33 diff.....that torque curve.... not to mention that it will be an all out race car with no interior and lexan windows and hatch. i think i can get it down to 2250 lbs or less.

let me sum this up: hopefully 300-350rwhp on a 2200 lb car with a 4.33 differential..... OH MY GOD

Justin

 

N/A engines are great....















...as long as they have at least 8 pistons and are over 5 liters

 

c'mon wheres all the guys with blown rx7!?!?!?

heheh

 

Well, the GTUs is a great car and all but it is super rare; it's more like a collectors item. The higher diff ratio is swappable from what I hear and can take higher ratios than even 4.33, especially considering Mazdaspeed is coming back.

What I would do is buy a TurboII, which is much easier to find, and rip the engine out and sell it or, if it's blown, turn it into a coffee table item. If the motor is blown you're goin to get a TurboII for real cheap, if it isn't you can sell it to someone who needs one...and there's always someone who needs a new turbo motor. Then you want to source a Renesis motor *crosses fingers and hopes that Mazda is going to offer crate Rennies*, put that in, and get a super high diff ring from Mazdaspeed or someone--like a 5.0. Bam, there's your GTUs with Rennie power; it's got all the Turbo goodies like the GTUs with an NA motor, only it's better!

Funny, Mazda should have offered the GTUs as the NA version of the FC from the beginning, and it would have sold many more units than the TurboII.

 

i think the turbo guys will stop putting us down when the RX8 comes out. its n/a and i have no doubt it will have lightly to mildly modified TII's seeing taillights. its taken a long time but it is N/A, hopefully one of those things will fit into my FC n/a haha

 

o another thing i got 24 mpg out of my n/a on the highway and that was with quite a few times where i redlined 3rd gear to pass people.

 

Super high? You're saying you want 2.73 gears?

Higher gear= lower numerically.

Too bad all you people are only adressing hp. Torque is what moves the damn car, and is one thing an NA can only dream of. So mod up your Renesis. I'll still kick your ***.

 

the Renesis has a whooping 160ft/lbs

 

Okay, the intricacies of diff gear description I've never studied. I always considered a number like 3.9 or 4.3 to be high numerically and have just referred to the gearing as "high" in my descriptions; old habits die hard and I'll probably always be referring to a 5.0 ratio as "high."

Anyway, the lack of torque off the line in an NA can be greatly enhanced by an absurd rear diff ratio like 4.6 to 5.0. I know turbos are great and all but I don't like the complication and detonation prone problems that they can have, especially considering it can ruin a rotary quite quickly. Besides, there's more to owning a car than just "kicking other peoples' asses." If that was my only goal I'd be saving for a Renesis, turbo kit, and NOS...but guess what, I'm not. My idea of swapping a Rennie into a TurboII is simply to offer a very streetable, reliable, and fun to drive car that will take all the beating you give it and give ya reasonably good gas mileage to boot. No excessive overlap or super loud exhaust to reach acceptable HP levels, like bridgeported motors, or fears that can come from over revving a turbo motor or not letting the motor cool down.

 

All depends on what you want, you looking for a fast car or a quick car? You want fast, get a NA you want quick, get a turbo. NA will give you a higher top speed, but turbo will accelerate more rapidly. Just be glad you got a rotary.

 

What the hell are you talking about?! Top speed is about one thing only: power. Comparing two similar vehicles, the one with the most torque will accelerate faster, the one with the most power will have the highest top speed. Last time I checked the Turbo had a lot more of both...

 

He might be reffering to rpm range.....?

what should be done with a 90 GTUs???? (currently with no engine or tranny....)

Justin

 

Yo,


You buy it off the junkyard, tow it home...then look for a donor vehicle for the engine/tranny. If the GTUs still has the rear axle/diff, then you're home free. Go for it!

KS
1989 GTUs "It's black, right?"

 

yeah, i kinda figured that much, yes it has the diff and it is red. i meant should i restore it to stock "looking" condition or make it all out race.

Justin

 

Easy choice, ALL OUT RACE, get a S5 motor and B-port that bitch and mod the crap out of it, keep it all N/A and make a 2200llb lexan 300hp screamer!!

 

i will definitely mod the engine, but seeing as it is a rarity i think i might be better off taking a sport and making it all out race. i dont want to go and weld in an 8 poitn roll cage to a collectors car
