Don't forget "after you forced her to have bigger ***** and a bigger *** through surgical incisions." (For the rotary, of course)

When it comes down to it, it's hard to do a fair comparison between the two. I mean, GM did a great job lightening the LS motors, so if I were to compare, I'd have to swap out all my irons for aluminum front, center and rear housings, and use lightened rotors. Of course, that costs a ridiculous amount.

I'd also have to rebalance the rotating assembly and port the motor until it makes the same peak hp @ 1.5x the rpm that the LS1 makes it at. Then, try to mate the motor to a T56 and get a custom rear differential with gears 1.5x the ratio of the popular rear ends that everyone uses.

Of course, then we'd have to do the reverse test as well, once again porting the rotary engine so it makes the same peak hp @ 1.5x the rpm of the LSx engine. Next, try to shoehorn the R-type transmission onto the LSx engine (probably not going to work.) After that, locate Final Drive gears that are 2/3x the ratio of the popular FD rear ends that everyone uses.

Why use the 1.5x /2/3x ratio's? To compensate for the rotary engine's internal gearing differences vs. the pison engine. That way. it'll keep top speed and power peak consistent across both reference frames.

However, this will cost a bazillion dollars and probably never get done. I still don't like the feeling of the LS1FD while it corners, could be the changed polar moment, I dunno.

I wonder if anyone has ever tried shoehorning the T56 into a 13B/20B. If not, you could find a custom 6-speed transmission with the same T56 gear ratios to mate into the 20B and the LSx rear end. As well as finding a custom 5-speed transmssion to mate with the LSx with the same FD gear ratios and compatability with the FD rear end.

 

None of us have the R&D budgets of car manufacturers so indisputable numbers will ever be achieved in this comparison. The best we can hope for is a friendly competition that makes life just a little bit more interesting.
I am glad to see that some of the morons seem to have left the thread and most of us can actually get along and joke about it (with the exception of 1 or 2 still remaining).
I never quite understood why people have this incessant need to have some sort of rivalry and will go to any measure to create one if its not there.

The point to all of this is that it takes a certain type of person to own a Turbo Rotary or a LS1 RX7. Morons like a few that have come and gone on this site over the past few years are the ones that give these cars such a bad rep. They buy some POS FD or TII and without talking to anyone start throwing on intakes and exhaust. Before you know it, they pop the motor because they leaned it out too much and are bitching to their friends because the motor sucks instead of coming clean about how dumb they were.
From what I have heard, most of the LS community comes from a few distinct areas
- People who were domestic owners who love the idea of a domestic motor in a beautiful chassis
- Former FI rotary guys who are fed up with dealing with shady mechanics, poor rebuilds, and conflicting data
- People who love the idea of a NA 20B but don’t have the money or the faith in the replacement parts community to attempt the swap.
- People who believe the reputation of the rotary and like the swap because they have the race engineering and drop dead good looks of the RX7 and a motor that they think is reliable

Honestly, I come from the second and third group of people. I really don’t trust the vast majority of rotary mechanics in the US. I just got tired of having very little choice in who I take my car to and since I don’t have a spacious garage and workspace, I couldn’t have that as an option to work on my car myself should something along the way prove problematic. I wish I could but I couldn’t afford to keep my workspace that I used to do the swap. I honestly believe that the reason we have such a problem with turbo rotaries in the US is that not enough people know how to modify and tune them properly. I have seen too many instances where someone does something stupid and the motor goes pop because of it. The FD is a race car and requires the maintenance of a race car. If you cant live up to that then you should not own one. This holds true for rotary and ls guys alike.

 

no merlin. it was not.

 

i was curious and searched tommy's posts.
it would appear he does have a very fast car. i def think a road course is in order.

 

QFT

When you had your turbo rotary, ever try KDR Performance in PA?

 

I have talked a lot with the guys from KDR and had it worked on at some of the best shops in the DC metro area.

The issue is this. Do I really want to have my car towed all the way down to philly everytime it needs work done?

 

I think so?

 

So what? A fast car doesn't make you God. Hes gonna learn that fairly quick. Maybe not even from me..but someone is gonna stomp his ego and its gonna be very enjoyable.

 

It's more enjoyable for us to bench race than real street racing

 

eh, its not that fast. its only a 10.5 car at best.. maybe a 10.4 because thats what my video shows and we all know numbers to lie. thats all i can get outta her. time to start my ls swap. do the ls swap and .............


you TOO can join the anti-idiot club

 

wats up iam a fellow v8_fd owner...my car isnt anything 2 special jus a stock ls1 stock 6speed on the shot..if u want 2 try somthing out from a dig drop me a pm...iam located in new york.

-dj

 

Please get some video!

 

One more category

- Those that want a super car's handling and power, the torque of a V8 and want to race and drive a very quick car, ie: those who want performance. After all it worked for Carroll Shelby

Oh and........Lingenburger

 

A properly sorted NA 3 Rotor can be quite powerful. They just need to build new ones.

Just check out Mr Amimimimiyama

 

lol, his pport is conservative! You have street ports hitting the numbers he makes.

 

If it's not on a road course, who cares?

 

crazy

 

You can't say it anymore honestly then this:
" I honestly believe that the reason we have such a problem with turbo rotaries in the US is that not enough people (piston heads) know how to modify and tune them properly. I have seen too many instances where someone does something stupid (domestic owners) and the motor goes pop because of it. The FD is a race car and requires the maintenance of a race car. If you cant live up to that then you should not own one. V8 owners on the other hand a V8 race car is far from a real race car.

What makes a LS6 rx7 going beat a 20B? AAHHHHH NOTHING. This is going to be one *** raping he won't forget? So confident , and yet so ignorant of the true power that will defeat him, ... bAdly. " I HAVE NEVER BEEN IN ANYTHING FASTER" 1000hp muscle cars , 800hp supras, modded Z06s, (my fd, which is pretty damn quick), I'm telling you V8 heads , i'm just trying to warn you. heh, heh, heh.

 

Were you born full of **** or did it just build up over time?

There is nothing magical going on inside of either motor that gives you some super advantage. I love it how some people believe that the 20B was sprinkled with pixy dust and can make a car 3x faster with the same horsepower.

If you want to prove yourself and/or stroke your ego then come out to one of our events this year. I posted up the link in the NE section so it should be pretty easy to find. Come out. You might win or you might lose. The only thing I can tell you is that any attitude needs to be left at home. This isn’t some grudge match that people make it out to be but a good hearted competition.

 

I have driven turbo and PP NA 20B cars in Australia, decent power but not earth shattering, no more than a well sorted LS1 with thought out mods.

What do you think a twin turbo LS1 is going to make?

Bottom line though , for my style of driving and racing the V8 makes more sense, I love torque and can still pull 7000 rpm on my DD

 

ssssshhhh,,,,, my car only runs 10.5 at 12psi remember. and only makes 663 due to running out of turbo. sssssshhhh it doesnt make anymore power. im on ultra high boost
lol my video says so

 

probably over 1000hp. so what, whats that going to do on a 8.5 tire on the street besides make a 12 sec pass sideways at 150mph. im matching my street car to other street cars. Im sure a twin turbo ls1 tubbed out will run a great time. but its not a streetcar.

 

Heh, is this you trying to be sarcastic? Show me you going faster and then we can say you went faster. Until then your car went 10.5 which isnt that impressive...663rwhp to go 10.5? Honestly thats pathetic. It takes you 663hp to go mid 10's and it takes an LS1 guy high 300's (398rwhp) to go .4 seconds slower than you...like I said, pathetic.

 

10.5 @ 12psi .... missing a gear... made 585 on 12psi.... i made 663 @ 18psi.

I made 530hp on my 13b and went 10.8 @ 132 on drag radials

I dont care if you believe me or not. i dont need to post a video to prove anything to you. im just going to smoke you when i race you.

You are pathetic sir, get your car done.

 

BTW: i dont care if you have somthing to say about me missing a gear either... it was the day after i got the car tuned and the day after i installed my new trans gears. I never launched a 20b, let alone with those new gears. didnt know what rpm to come out at, when to shift the trans because the gearing was different etc etc... bottom line is.... i ran it the day after i got it done on a totally different set up, ran the car twice..... the first time, was the 10.5 pass, and the second time was later that evening due to an oil down on the track so when it was my turn ( 2 cars back) that track just was not sticky and i was spinning and just let out.

So in conclusion, i did pretty good for a not knowing how my different setup was going to react. 10.5 on 12psi (missing a gear, not the perfect launch, not holding 2nd at all ) first and only time out with a different animal. let me know what your first pass is... *****
