Ls1 FD or Rotary FD?

I am in a fix. Which way do you guys think I should go with this thing? Should I ditch the almighty rotary and go with an ls1, ls2, ls6 or ls7 swap with a t56 tranny? Or the other option would be to go back to a rotary engine. I am thinking to do the ls swap with the t56 because of all the torque and horsepower and how the car wont break down on me every 20 thousand k.. any input would be appreciated. Thanks

My 2 cents:

If you want a LSx motor, just get a Corvette. C5's are under $20k right now. You'll have the motor and a much more updated car. The main downside to the C5 is the interior door handles, however the FD's aren't really any better in that regard.

get the LS1 swap.. the rotary is trash, all these guys are gonna tell u is what mahjik just told u... if u like the look of the import.. but want the speed of a muscle car.. go LSx.. im doing the same.. mines gonna be turbo.. dump the rotary and go LSx, if u look around the site, u'll see about a dozen or more guys that have 20k rx-7's.. w/ single turbo's.. pushing well over 300hp.. going LS1.. u dont need anymore proof than that.. and ur right about rebuilding it every 20k miles.. w/ the LSx swap, u can DD w/out no problems.. and u dont have to worry about throwing out an apex seal everytime u have to get on it to pass some1..

Just make sure you have the bolt-ons and that won't happen.

heres how i look at it. i love both, rotary and LSX. there are reliability issues with rotaries once you reach certain points. there are ways to overcome them, but can be a hassle.

ill ALWAYS own a rotary car, ALWAYS. i ******* low the wankel, but for my FD id go LSX. it looks great, handles amazingly, great NA power, and decent economy.

I am not a rotary die hard. I can certainly see (and contemplated) the benefits of an ls swap *but* never let TT Rotary sway your decision. I’ve had a couple of conversations with him and determined that the kid isn’t too bright and certainly does not think things thoroughly.

This is his story:
He is a kid on a tight budget who bought a less than desirable FD. That’s 2 mistakes right there: tight budget alone is tough on a good FD, never mind getting a crappy one. All he did was bitch and moan about how everything is expensive on the FD without a clue of why nor how the prices are higher than a let’s say Honda parts. I don’t know if he blew his engine but he sure talks like he did.

Now he is on this Ls bender/ rotary thrashing mode which is ok except that his reasoning is all fucked up (yeah I know as expected). This is a list of misconceptions that he has:

1) torque wins races not hp…
2) He is not mechanically inclined so he has to get a shop to do all of the work. Yet he is very optimistic about the price that it’s going cost for the swap. An ls swap is a full custom job when is that ever inexpensive? Nevermind that he wants to add a turbo but has failed to mention the price associated with supporting mods? As well know they always drive the cost way, way up. Let me say that again: way up.
3) It’s going take lots patience, money, and perseverance to finish the job that he wants. Which I doubt he has any of those qualities.
4) He seems to believe that his 28xxx fd will be drivable at 600+ RWHP with TORQUE to match. Yeah right…


I will say it now. TT Rotary will never finish his LS swap. On the list of misconceptions number 2 and 3 will ultimately break him and he will have to sell the car as roller. If he was truly smart, he would know his short comings and therefore sell his supposedly running FD, then pony up additional cash and buy an already running ls converted FD.

I think you're full of **** to be honest. You expect me to believe you can put together a turbo LS1 swap for $9k? BUUUUUULSHIT! I bet you haven't actually put any real thought into it at all. A good pullout costs $4500, the swap kit is $1700, and the labor is at least another $1500 but more than likely a lot more considering the shop you were talking about, I'd guess $2k at least. Those are the big parts, then you have all of the little stuff associated with it, like a new radiator, $125, radiator fans, $65, all new lines, ~$150, wiring harness (which can be costly depending on where you get it), intake, ~$150-$325, fuel pump, $100, exhaust work, $150, etc. etc. So all of that right there, if we take the absolute lowest figures I quoted, totals $8440. That leaves you a whopping $560 for the turbo, the intercooler, the intercooler piping, the manifold, the wastegate, the BOV, and the tuning. That's just to get it rolling, if you want it to actually be effective, you'll have to upgrade to larger wheels and tires so it'll hook up. Then once you get it going that fast, you'll want to be able to stop so you'll need upgraded brakes as well. If you're running at a track, you'll need a cage of some sort also.

So tell me again, how exactly will you put together a turbo LS1 swap for $9k?

the kit is $1200.. so ur off about $500 on that.. and ur prices are max priced.. its called bragaining.. or negotiating.. "hinson super cars" subframe kit.. is 1200.. go check the site, i just now read ur whole post.. lol.. this isnt going to be a track car.. if i were to run slicks or a good tire.. i would need a different suspension.. the car is mainly to cruise around and have fun in.. basically a street monster/showcar.. so therefore i will be driving it... MAYBE.. twice a month.. if that.

You're living in some sort of alternate reality. LS1's are not cheap, no matter whose shop you get them from. They're actually increasing in value since we seem to be snatching up most of them now. LS1's, in stock form, run around $3k. T56's go for $1500. Nobody has LS1's laying around unassembled in a heap, and if they do, they're not complete for one reason or another. And no, all of the rest of the parts don't come with the ls1. You'll need a custom made intake of some sort, you'll have to have the ls1 wired into the rx7 harness, you'll need a new radiator from an older corvette, you'll need a taurus fan for that radiator, you'll also need all new lines that have to be fabricated. The fuel pump you'll need if you're going to be running anything other than stock hp levels, and since you want a turbo, you'll need a lot more than that. That leads to larger injectors which run around $300 since you'll probably need at least 42#'s. You need the entire turbo kit which is going to cost thousands more. Even if you do get the turbo kit, you realize you're incredibly limited as to how much boost you can run on a stock bottom end? You'll need new rods, pistons, rings, rod bolts, another nice chunk of change there. Are you getting the point yet? The only thing a shop can cut you a break on is the labor, the parts have to come from somewhere and they're not going to just give them to you, you WILL have to pay for them. Your project is going to run way over $9k, no matter how many favors they owe you.

That price is a sale price and I'm sure it won't stick around for long. And my prices aren't maxed, unlike you, I just put one of these together, so I actually know what I'm talking about. You say it's not going to be a track car, but you're wanting 900hp??? I don't know what size rims you have now, but you'll need at least a 275 out back and some REALLY sticky tires, especially if you're only going to be running on the track. And no matter whether you're running on the track or on the street, you're still going to need to stop. The stock brake system simply can't handle that much power.

the engine is out of one of there mustangs.. the t56 is laying in there shop.. literally.. extra tranny, they deal w/ all sorts of LSx based motors.. all sorts of different customers come in.. wanting this.. wanting that.. selling this.. buying that.. and they just keep the stuff in stock.. and the motor has ironheads.. not aluminum.. and the motor will be able to hold up to about 10-15 psi.. most likely 10.. im not building a race car.. and it will already be cam'd.. ported.. like i said.. the wait is extraneous.. but.. i will post pics up when i get it done.. to prove
every1 wrong on this forum.. and its not "THE" ls1.. its a lsx based motor.. its in the lsx family.. 323 ironheads.. the motor that comes in the Z71's.

where did u see 900hp?? my car will only need 500-600..it'll be in the high 500.. 560-580.. 600 is max.. and i will not be running the car at the track.. maybe once or twice.. but i will not be running sticky tires.. it'll snap the rear end right off.. the rx-7 stock suspension cant handle it.. gives it to much shock.. i will have traction issues.. but.. who cares.. it wont be a daily driver or a track car.. it'll just most likely be a showcar/cruiser.. just something fun to have... i've always been into imports.. but never liked how muscle cars always out performed them.. so.. im taking the look of an import + the power of american muscle

That's where I read 900hp. And if you're not even going to be using an LS1, I don't know why you're arguing about the price of hinson's kit, the shop will have to fabricate something up on their own. That 323 won't work with the hinson kit, as far as I know. And if the engine comes out of a Z71, why did you say it was out of a mustang? You'll also need an adapter plate depending on where the transmission came from, more money. You're just not being realistic if you think they're going to give you or even cut massive amounts of money off of these parts. It's still going to cost a lot, no matter what you may think or hope.
