Because when you launch a car, the weight transfer to the back of the car. Since it already has an engine in the rear, its getting the weight of the engine and force of launching. That's when tires hook up the best, thus far a MR2 is 'easier' to launch from a dig. Since you kept up with him on a roll, once hes ahead of you from a dig, you don't have enogh power to catch up to him. If the MR2 is underpower then yea, he may keep up with you at launch, after that its smooth sailing.

 

^^^ Ok... i gotcha... good point

 

Has anyone raced or beaten one of the 05 v6 mustangs with a n/a 90 rx7, hear they have 210 hp and 220 tq, not bad for a v6.

 

Er? That doesn't have alot to do with the thread Ed.

But, I go compare 1/4 mile times, add .5 (with no mods/no engine mods) to a FC and see who wins. I bet you'll need mods to hang with the stang.

 

he prolly didnt adjust the boost b/c mr2 will get more air in the second cylinder and blow a ring so you NEED to get intake manifold and aftermarket ecu if you up the psi (unless its like 2 psi) i know b/c my friend has one

 

are you coming to the seven meet on april 1st? its out in beavercreek dayton i think. go check the ohiorotaries board and look for post.

 

I've seen them with more then 2 PSI of boost though? And without an aftermarket intake manifold.

 

So Chris... did you think I was lying about the numbers I want to put down with my actuated 1/3 BP in the bored at work thread? 190's hard, but it's usually just in th porting work. A good port job, and a well built motor = 190 whp easy. A BP and a well built motor... time will tell for me (sometime around mid-summer hopefull, especially if I can get a 2nd job in the evenings).

 

Yes i coming on april 1st. good times

 

Your friend doesn't know what he's talking about then...

 

Hey, Anti-Rice... I not only beleave you, but i want to know how your pulling 190hp? Ive got an S4 an i wana keep it NA, but have some power to move around... I dont know if it was stated or not, but could you give me a few tips on how to do that?

 

Nice Kill Anti-Rice Cannon

Taken from a thread posted here:

Get an ignition. You will notice a good gain above 6k rpms in 3rd and 4th gears. The gains through the rest of the powerband will only show on a dyno, not much in the seat of the pants. This will also help other things as well, mpg, drivability, ect... Not super cheap but easy to install and worth it. Check out rx7.com for the Jacobs FC1000 ignition. $180.

Port and match all the intake runners on the intake manifold. Don't get out of hand. Just match a factory gasket size and make the transitions between the manifolds as seamless as possible. This will also make a noticable difference above 6k rpms, but is all 5 gears. Cheap but time consuming.

Make a cold air box and a way to get fresh air to the airfilter. If you keep all the engine air (hot air) from getting into the intake you will notice a difference in all driving conditions. Cheap but time consuming.

Pinapple racing 5+6 port sleeve inserts. Slid these babys in when you have your intake off for porting. Better top end flow. $50 for these guys.

And the most important thing would be a piggy back and a tune. This can pick up a chunk of HP on a stock ECU NA. I have seen 15-20 whp on some nicely modified NA's on this forum. This of course is a little more expensive but very doable. Get a used SAFC $150-200 adn set up a tunning session at a local shop $200-300.

That should keep you busy for a while. All of the above will add/free up HP and make you car drive better and get better MPG. Alot more fun to drive is also a bonus.

 

Great kill!

Heck, i got a ride in a stock N/A MR2 once, and i was impressed. I would want one, but you can fit lots of stuff in the hatch of the fc, basically nothing in the MR2.

 

Uhh no, 3sgte is a durable motor that can take 400whp on stock internals. My mr2 runs 10-14 psi daily on a stock motor. The only ppl that get a intake manifold are mr2's that are making more than 400whp. The only time u need a piggy back or standalone is when u upgrade the fuel system. An mr2's can run up to 16 psi on the stock fuel system.

 

Heh, visit the Mr2 forum(can't remember which one), but once you get done reading why you shouldn't get an MR2, you be happy with the results.

 

do i know you? were you that one guy that offers people head? maybe you were just kidding like you always are

 

Your car isn't exactly the normal N/A. If we're talking generalities, then yes, N/A's are slow compared to TII's.

Hell, you could say N/A's are fast, but be running a PPort. That's not exactly fair to say though is it?

And yes, I own an N/A.

 

i was thinking about getting a 1st Gen MR2 before I got my FC. i think that they are nice cars and if i had the chance i would pick one up in a heart beat even a shell. try and put a N/A rotary in it....

 

wow.....back from the dead haha.

Idk....there just is alot of N/A haters out there. I dont seem to get how one rx7 owner could try and flame another rx7 owner. And if you say you have an N/A people normaly write you off as a bullshit story, its just a little annoying thats all.

 

care to elaborate? I willing to bet you don't have the slightest clue about MR2's the only thing i can think of is the snap over steer issues, lots of guys on the forum steer younger drivers away from MR2's because too many dumbshits wreck them them shortly after they buy them.

to clarify a few things stock mr2 turbos put down about 165rwhp. turboback, mbc, and a sidemount intercooler upgrade will put them up to 230whp. nice kill btw, that's impressive for an NA.

 

i agree, my borthers was at 13 psi regularly w/ a dp and bov. nothing else and it never blew up. lol

 

actually the stock fuel system can handle stock turbo well out of it's efficieny range. Mine's been running 16psi for 3 years now with zero problems.

 

Good kill. I was thinking of trying to squeeze some good power out of my S5 as well without the aid of forced induction. I was thinking a half bridge/large streetport and RX-8 rotors (higher compression) in addition to stuff like ignition, intake, exhaust, etc. would probably net at least 200rwhp. I'd really like to squeeze about 250rwhp... I know I know, I sound crazy, but I'm gonna try dammit!!!

 

maybe I'm not educated enough about modded rotaries but a turbo mr2 pulls about a 14.5 STOCK and a TURBO Fc pulls about a high 14 low 15... lol call me crazy but maybe the guy didn't know how to drive?

I've owned 4 mr2's (1 turbo, 1 Supercharged, 2 NA) and 2 FC RX-7's (1 turbo II and 1 NA) my turbo II was about as fast as the SC mr2 but my turbo mr2 would blow the doors off of both of them...

 

LOL...I'm happy this thread is still going, becuase I was reading through it as a current MR2 and FD owner and laughing to myself at all the misinformation. A couple of you seem to know MR2s...but just to dispel a few rumors and back up soem of the CORRECT statements in this thread:

-A stock MR2 puts down 160-170 whp, 200 bhp. With basic bolt ons (downpipe, exhaust, MBC) it puts down 220-240 whp. The safe limit of the OEM fuel system is 275 whp. They have been known to pull low to mid 14 second quarter miles bone stock (genII) or mid to high 13s bone stock (genIII). Lightly modified (BPU) GenIIs can run high 12s with little to no effort. My MR2 with a few bolt ons and a Greddy Td06 turbo kit ran a 12.9 @ 108 with a 2.0 60'. With better driving I could have pulled a 12.6.

-My MR2 put down 400 whp UNTUNED on a stock intake manifold. Yes, they can run lean in #3 (NOT #2) if you don't know what you're doing. If you know what you're doing you simply trim the fuel correctly on that cylinder. You don't need to even worry about trimming the fuel unless you're at over 300 whp.

-If the MR2 was at a "roll" and bone stock you could probably have taken him, 165 whp vs 190 whp. If the guy had spent $10 at home depot he would have taken you, or if you went from a stop and he coudl drive he would have taken you. MR2s can pull under 1.7 second 60' bone stock with good tires.

-For those that said "go look at the MR2 board and you wont want to own one"...I challenge you to go over there and take a look at the community and level of support/owners love for their cars. It blows this community out of the water (no offense) and those owners love their cars more than anything. I, myself, am on my 15th or so MR2 (own 3 right now) and can't get enough of them. Sure, I like my 93R1 FD, but its not the same as an MR2 and if I could only own one it would still be an MR2.

MR. MR2 owner
