mk3's can run 13.5's with a dollar's worth of washers to shim the internal wastegate, intake, and exhaust...what's your point?
I know there are quick 2nd gen rexes, however I have not come across a single 2nd gen that could pull on me drag racing. I'm sure you don't come across quick mark 3 supras often.
rx7: Looks badass. out handles the crap out of my car.
mk3 supra turbo: heavy, runs rich stock, gets richer with intake+exhaust...aftermarket is very expensive. not many sub 13s ones in wisconsin. fastest 7m powered mk3 runs 10.66, and very few bother with road racing. body roll, oversteer...suspension needs a lot of work.
300zx turbo: economy turbo...kinda like the 1g eclipse turbo! my girlfriend's brother has one. his suspension seems worse than the supra, but it could just be worn from all the years of abuse.

I have a cuple friends with black top sr20s , there quicker off the line but 1jz are stronger in the long run.

ive seen plenty of mkIII's run mid to high 13's with exahust and intake, with the washer method to shim the wastegate........ im not saying rx7's are bad but you guys are bashing them like they have no competition..........

I own a TII however I've worked on both. Engine swaps aside the MKIII Supra fitted with a 7MGTE can't really compete when you're talking about an all around sports car. The RX7 out handles, and out powers (to weight) the MKIII for the same amount of money.

boostaddctn on supraforums.com ran a 13.5 with the wastegate shimmed to 11psi, intake, exhaust. Nitto 555r's. I've seen the slips, I have seen the video. he didn't have the best 60' time either. I can post the slip if you still want to call BS.

even so what does that prove. Give an rx7 nittos, intake, turbo back exhaust and a boost controller set to 10 psi or so(fcd to keep fuel cut down) and it will be right there too. And exhaust for rx7s is cheaper for the most part(unless you go custom). I would say money is similar for drag results and handling has already been discussed serveral times.

And for the last post. The mkIII's need a FCD too or a lexus afm in order not to hit Fuel Cut..

fuel cut on the mk3 is 14psi. what is it on an rx7? not an argument, just wondering. is there a simple mod like the lexusv8 AFM + 550cc injectors that will raise the rx7's FC?
obviously on an mk3 the 550cc + lexus afm mod should have an adjustable fuel pressure regulator, fuel pump, and an safc2 to get the best gain from the mod...but it does raise fuel cut to 27-30psi.
touche...exhausts for the mk3 are rediculously expensive. most people make their own. $600 for the HKS turbo cat back. Mine was 3 hours of welding, 2 hours of flange milling, $200 in 304 stainless steel.

?
wasn't this forum for a stock for stock comparison???
just use the hard facts of the two contenders.
drum roll... in the right corner the toyota supra turbo weighing in at...
3534 lbs.. producing 232 horses and 254 lbs of torque.(being generous and using hte most powerful version of that supra produced because the earlier years had about 8 less lbs of torque and 2 less hp..0-60: 6.6-7.2( from various sources)
qtr mile: 14.9-15.2
in the left corner... Mazda RX-7 Turbo ( italics means 87-88 Turbo II)
1987-88 Mazda RX-7 Turbo... weighing in at 2830 lbs...producing 182 horses and
182 horses and 183 lbs of torque.. 0-60: 6.5 second, qtr mile: 14.9
Also in the left corner... 1989-1991 Mazda RX-7 Turbo weighing in at.. 2850 lbs producing 200 horses and 196 lbs of torque. 0-60: 6.4, qtr mile: 14.7 ish so many different times around im just averaging really.
THERE YOU GO YOU GUYS DECIDE WHO THE WINNER IS LET THE DEBATING BEGIN!

not true, the most powerfull mkIII had a 2.5 twin turbo which produced 280 hp...... with a quarter mile time of 14 seconds.......... they also had a twin turbo R version that was much lighter..........

I have a cuple friends with black top sr20s , there quicker off the line but 1jz are stronger in the long run.

If you think that you're going to say that these cars are "basically the same" because they share the same chassis, then ****, why don't you try importing one into the US? Just because it's RHD, it's still "basically the same," right?
For that matter, in this market, where it matters, none of the engines you were talking about came in the cars you were talking about. A JDM car is not equivalent to a similar-looking USDM variant, and the NHTSA can help you out if you're having trouble coming to grasps with this concept.
One more example of the fallacy of your argument: the IS300 comes with the 2JZ-GE engine. Do you know how much of a pain in the *** it is to swap in a 2JZ-GTE? There is more involved in engine swaps than just the money you spend on the engine.

but I still dont get your argument... an rx7 here is still called an rx7 in japan, along with the supra. They came in different trims, with different motors and packages. They had the 1jz, the 7m, and also they had the Turbo A IIRC edition, which was the most fixed up or most powerfull version.

NO.
Can't you read my profile?
even though the 1jz was not offered in the supra in the us, its fairly easy to obtain and swap, which i did.
Last time I checked, it wasn't THAT easy to get.
How much did you pay for it?
I bet you paid more than what it costs to get a 7MGTE.
Go away.

I can pull the plug on the boost sensor and instant no overboost fuel-cut.
You want to boost to 20psi?
Sure, the stock ECU won't hold you back.
I dunno how long everything is going to last though.
Seriously, do your research before putting all this crap on here.
You're wasting your time preaching to us.

ok reted......... your a moron for saying anything about how to install a 1jz...... it's a pretty straight forward swap.... only difficult thing is extending the wiring harness.... and swapping some body plugs..... and of course your gonna pay more for a 1jz, its a far more superior motor, even though its .5 liters smaller. Don't talk about something you've probably never done............. and on the fuel cut note... why are you beeing such and *** about it, he was just asking a simple question, i belive its at 10 psi, correct me if im wrong.
And there have been 2.5 jza70 supras imported into the us......... the only thing is its probably cheaper to find a shell and get a front clip, thats why people don't import them, they sell half cuts........

STOCK USDM COMPARISONS guys..****.
the 1jz did NOT come on any supra period, in the USDM, which means it's exempt from this competition.
Argh...this thread makes my head want to explode.

Ted, atleast here in Miami we have like 1000000 importers. Many of them stock like one or 2 1j's and the rest 7m's. 7m's are like a dime a dozen, from the same guy that sells me my motors, 13bt's longblock with tranny 1100, comp guaranteed. 1 month Warranty against any seal damage...I get them cheaper alot cheaper, as I had bought more than 4 motors from him. but the point is that regular price is 6 or 700 for the 7m longblock, and 1200 for 1jz. I do admit though, they hold power good. I know this one guy called smiley, how has over 900hp stock block, modified head(port polish and angle job). Using an safc and profec e1 to regulate boost. AT low boost and off the chart afr he managed a 690.

nobody said stock usdm cars only, when i first started to read the post the mention that a jza70 was just alittle faster than a n/a, that automaticaly brings it into the argument
