do the two of you (thread starter and you) have some sort of prior beef of some sort?

 

nope i can only assume rotary jealousness

 

ok i read the whole thread again, and i still dont undersnta what u guys are arguing about, your install of the sr20det in the FD is clean and u did a nice job, ill give u that. but the horsepower #s and the tiem u ran are not that impressive, a mildly built fd can do the same doign it more reliably thenteh sr20 motor. how long will that sr last u at thi slevel, i can tell u not very long i have seen lots of sr30 motrs, not a lot of peopel push them passed 500 hp.

as far as vosko goes he is boostign 10 psi with over around 400 at wheels, his 12 second pass doesnt mean ****, he is just startign to get used to drivign the car, everyone who knows about that car knows its an easy 10 second car, so i donno what all this talk is about like he said it must be rotary jelousy

 

Well with most other cars, they are piston engines, so it's not a big deal when you swap it with another piston engine. But the RX-7 has a totally unique engine completely different than a piston, and 7's are becoming more and more rare. I just feel like when you buy a 7 a lot of it has to do with it having an engine that is very unique and different. Just my opinion.

oh ya one other thing, U JUST DONT GO PISTON IN A ROTARY CAR

hope u are follwoign this JIM

 

Did you read the part where he told you the number of 13Bs he went through before the conversion?

Its funny you said 'reliably' and 'rotory' in the same sentence.

whos fault is it he doesnt know what he is doign witha rotary?

 

For the most part, I agree. Six engines? With the same failure? WTF?

 

Swap whatever you want into any RX. Your thing is your thing. Nice fab skills.

 

wut does it matter how many rotaries hes gone threw, does that mean everyone goes through that much to? this is news to my ears

 

How many FDs on this forum are running similar numbers with the stock rotory?

I've been in the SoCal import scense for a few years now. I never see an RX7 run a decent pass. Only a handful of cars from XS running at IDRC.

you are on the wrong coast that is why

 

If you were getting only a few hundred miles out of a bearing something was WAY messed up.

 

The 1st motor crapped as the car was purchased used. We had my good buddy, Marcus Williams, to build the motor with all the bells and whistles. It spun the front bearing because the belt was too tight after 200miles. He built the motor again through Marcus and it again spun the front bearing. We then flew Marcus down to FL to rebuild the motor at our shop. I watched the entire build and everything was mic'd and measured to assure everything was in proper shape. The motor went about 2K miles and crapped again. It was not a tuning issue, but the front bearing. I suspect it may have been something external to the motor such as the oil cooler setup and or thermostat. The mystery got very expensive and it was not because the motor was improperly built. I am sure some of you are aware of Marcus and his abilities on the rotary. Who knows, but it was time to move on to a piston motor. Hey, I think the FD is a beautiful car and that is why I want to mate it with a TT V6. BTW, Zhound, 300zxtt guy, nice times. My TT 240z went 11.2@130 with a crap 1.9 60ft. Here is a pic for giggles of my new intake and header.

 

Your 240Z is f***ing sick! . My friend that put my car together has one like yours...well 280Z though. It has very similar setup as mine plus some juice. I saw it run 10.6@135mph. Now that it'll make 140+mph traps.

 

Mark Leader, I spoke with him one day. That pass I made was 10psi off the line until 80mph when I went to 16psi. I also ran 100shot on top of that. The new longtube header and intake should increase power and I will run about 23psi. I hope to see 137mph! His car is damn fast and I hope to top his record.

 

LOL, small world. Actually this one is Greg Dupree. Mark has a white 10 second 280ZX and an 11 second Z32.

I'm sure you won't see Greg run again for a little while. The tranny needs some attention and he doesn't have time for it these days.

Nice cars you have. This is getting way off subject so I'll stop.

 

you know they should jus change the name of this website, where it says worlds largest rotary community to somthing like worlds largest piston community...what has this world come to. god it pisses me off. we got pple talking about there 300s and 240s wtf?? it clearly says RX7CLUB.COM not 300zx.com...

 

You're supposed to take the chill pill orally.

 

those pics were cool. thanks for posting them. the 240 and 280 are rad.

actually a lot are. and that SR20det isn't "stock" its using a stock longblock, so you could say, any rotary engine is "stock" because there isn't any way to modify the compression. Its all "stock" inside, except for seals, and some people are still using stock mazda 2mm seals and are in the 7s,8s,9s,10s... porting is equivilant to cams, so... i don't get your point?

He's got a pretty good size turbo on it, fuel system, and fuel managment. Nothing on that car is stock. the sr20det is known to be the "supra" engine of nissan. Personally, from what i know, the sr20det is a crap engine compared to an RB20DET which has a nice iron block, 2 extra pistons, and flows better, plus its cheaper... sr20det is just some JDM hype engine, likea b16a... but hey, what do i know, i drive an rx7? Either way, its a nice car, but not something i'd do.

I know it might just make sense for you to swing from some nissan nutz, but save it for freshalloy.com.

you must not get out a lot do you?

 

Vosko has a serious case of time slip envy, brought on by some nicer car than his red fever...... Don't worry because he is taking heavy doses of haterade to alleviate the symptoms, which include: 1) putting down the source of fever (my car), 2) stating excuses why his car is better, 3) using the famous words JUST WAIT UNTIL (insert claim of next action here) .

I built this car because i thought it would be fun a perform pretty well, it has been both however I and I repeat I have been able to actually drive the vehicle and take it on small roadtrips because i do not have to fear it braking all the time...... This was not done to put down any rotaries however i think sometimes alot of you guys are still in the romance period with these motors.... let me explain what i mean... you start dating a new girl, or guy, vosko i didn't want to leave you out.... I am sorry i could not resist... anyway for the first few months you can see her do no wrong.... but after a while you begin to see her faults and for me personally the rotary motor while being an innovative and trick design has many flaws, which have been covered on this forum a hundred times, the one flaw that kept getting me had something to do with the inadequate oiling system.... I do not hate rotaries and if they continue to be developed will be a great motor in every sense of the word.... that will take a few decades at least though..... The piston motor is still be developed to this day it just has a 150 years head start on the wankel

you just changed my mind the SR20DET is the greatest engine ever made because it went .9 seconds faster than my car with N2O and more boost and slicks

 

Wait a second...inadequate oiling system? You check the oil, you put the oil in, you drive the car, and its fine. The only flaw I know of for rotaries is the people who don't know jack **** about them, run lean, run bad timing, don't check the oil, and then they blow sky high so they blame the design. I don't give a rats *** if you make a piston conversion or not, personally a swap done correctly gets an A+ in my book. But making a swap cause you don't know how to tune or maintain your car is a pretty lame excuse.

94touring, 18psi for the past 25k miles and also daily driven.

 

No wonder the RX8 is not boosted Mazda and us poor owners have learned a tough lesson turbocharged rotarys dont last.Very well done motor swap though I wish I could install a inline 6 in mine like a RB26ETT.
