I just have to say it again. Single turbo conversions ruin the FD for it's intended purpose as a road racer. It sucks when the boost kicks in at the apex. End of story. Drag queen FD's are the TRUE abomination.

Cool silicone, I look forward to seeing your build post. Don't pay attention to the childish name calling. Do you think anyone in their right mind if they could have either for free and drove both would take a single turbo 13b over a 520rwhp LS7 FD? I think not.

Damn brother, drop a link of something....

400 lb-ft. RWTQ @ 3,000 rpm would be ~228 RWHP and 300 RWHP @ 3,000 rpm would be ~525 lb-ft. RWTQ. Which is it?

I have seen LS2 dyno's that confirm what I posted. Also I said over 400 lb-ft. Wow I can't believe some people on this forum are just as bad as Supraforums.

This is the dyno from a stock LS2 off the GM performance website. How does this compare to the information you have?

SMonty

that graph is just kidding. not a real article of proof and everyone on here is still right........

Eggie

Some of us just feel that numbers should compute when they're included in a post.

jimlab

Not "over 500 lb-ft."?

There's no way that an LS2 with bolt-ons produces more than 500 lb-ft. of torque (flywheel OR rear wheel) at only 3,000 rpm. Period. Maybe an LS2 with a set of really big sleeves?

Post actual values instead of throwing random numbers around and you'll probably get cut a little more slack.

I'll post a video after the weekend. I got running about a month ago and I'm going fishing in Wyoming for the weekend to celebrate. The last time I posted about my build, I was torched so bad by rotards that I had to go into a burn unit for a while. I haven't been back for a while. Rehab was a bitch. Like I've said before, I have nothing against rotary performance and loved the original configuration, but a single turbo wasn't gonna get me to where I wanted to go.

SMonty

I'm with ^..... bitches

Where in my post did I say stock LS2? This is my last post. You guys are unbelievable. My post was all about how much I can buy an LSx Rx7? Not is one better than the other. If you love the rotary motor fine. I don't want a rotary RX7. I want a RX7 with a V8 in it.

If I really wanted a RX7 with a rotary I could buy two of them for the price of a good LSx swap. If you don’t have anything positive to say about getting an LSx Rx7 please don't post in this thread. And like I said many times in this thread I love the RX7 and I love being different from the other cars that don’t have a rotary motor but I don’t want to deal with worrying about my dam apex seals blowing.

If you look for an RX7 FD for sale over 90% of them are on their 2nd or 3rd rotary motor. That should say something to you!!! I want a great power band and a reliable weekend monster.

You're looking at high 20's low 30's for a nice V8 FD.

Thats what im getting for my 94 Supra. So it will be an even trade. Thanks for the info.

So the general concept from the Dorito boys here is that because it's harder to make more power with the rotary, keeping it makes you more of a car guy?

And the general moral to be taken from this is "why succeed is an easy way when you can work much harder to fail?". I see. Makes sense.

jimlab

He was giving you a reference point so that you'd understand how your statement about LS2s with bolt on parts making 300+ RWHP and 400+ lb-ft. RWTQ @ 3,000 rpm was inaccurate.

BTW, GM High-Tech Performance magazine just did a side-by-side comparison of an LS2 with L92 heads and L76 intake and the same LS2 with AFR 205cc heads and a FAST LSX intake and neither engine produced more than 240 RWHP @ 3,000 rpm, which is 400+ lb-ft. RWTQ... it's just not 300+ RWHP or 500+ lb-ft. RWTQ.

On a side note, the L92/L76 combo edged out the AFR/FAST combo for about $2,000 less, and produced almost 500 RWHP.

You lied.

I think I'm starting to understand why the guys at Supraforums didn't like you.

That's a nice bike my friend. Larry's got some ***** to ride that 5 second rocket.

jimlab

Sure. You see, it's so easy to make power with big piston engines that anyone can do it, therefore it's not tragically cool like sticking with an eccentric (failed) engine design that wastes gas, sounds like ****, and barfs its internal components into the exhaust system if the planets aren't in perfect alignment.

People will grasp at anything to make themselves feel superior to others, even if it makes no logical sense whatsoever.

Makes perfect sense... if you're into that whole "the world is out to get me because I'm the only enlightened one in it" emo horseshit.

What I find amusing about the current FD/FC situation is that the "doritos" are trying to turn up the **** at the present with these huge-*** laggaliscious AI single setups that are now making upwards of 500-850 rwhp. They are no doubt doing this to make a statement that they can hang with the V8s. What is lost in translation however is that they are tearing the **** out of there engines by doing this and just asking to drastically increasing their rebuild frequency. I'm just waiting for a couple force Turbo’d/ Forged LSx FD to turn up the wick and redefine futility.

Owning a V8 fd is like being Crocadile Dundee. You know you have a big *** knife so there's no need to twirl it around and shi-

Thank you Jim. That was exactly the point I was making.

And BTW - I DO have a LS2 after having gone through the nightmare that is wasting a considerable amount of time/effort/money with a 20B. Do not rush to conclusions (obviously...) about people wanting to help facilitate the discussion. Nobody here is out to *get* you...cripes.

Per conversion costs estimates (general figs, you may or may not be able to find things for the same cost):
- LS2 engine and T-56 ~$9000
- Driveshaft/clutch/puck, etc ~$1500
- Headers, exhaust, etc ~ 1500-2000 (depending upon materials and single vs. dual)
- Electrical system wiring, loop checks, system commissioning, etc ~ $2000+ depending upon complexity of system
- Hinson, Granny, or custom motor/tranny mounting materials - $500-1000

- The rest is custom - radiator, oil cooler, differential, etc. Also consider if you do anything or have a shop perform the work.

LS1 is going to cost at least half on average or less but you're starting out with 50-100 less HP/tq. depending upon year.

Haha, this thread is great. Ive caught so much **** from rotary fanatics/v8 haters over mine. Ive heard every ridiculous comment from it will only be good for drag because of throwing off the weight distribution so bad, all the way to why take out a good rotary to put in an unreliable and week LS1. Its great so many people think so highly of their own opinions.

peachykeenwight

Aren't you the guy who for the longest time thought that you were making 400 rwhp with a GT30/35R (or something of the likes) and then decided to let the whole world know that you wanted to make 500+, consequently making an *** of yourself?

RISEN

15k to make 450 rwhp? My friend with a z06 just put in a $400 G5X3 CAM, $800 headers, got the PCM tuned for $200 and made 430 RWHP with everything else stock. That's nowhere close to 15k!

My FD LS1 RX7 project so far has cost me only $7,400 and that is including the engine/mount kit/car/radiator. I just need to spend another ~$1,100 and it'll be up and running with around 300 RWHP. $8,500 for a LS1 RX7 is not too bad

Drop down $1,500 for some nice heads, $400 for a nice cam, $800 for F.A.S.T. intake manifold, some tuning and it'll be making 420-440 rwhp with ease.

jimlab

He was talking about everything required to install an LSx engine in an FD.

I'm sure it will be absolutely lovely, and the fact that it has a salvage title won't bother anyone because you plan to keep it forever...

RISEN

It has a clean title

I purchased the roller for $4,800. It came with the Rotary (blown), Apexi PFC (Sold this for $850), lots of little mods here and there. I sold all of the stuff for $3,900, so that's $900 for a clean title FD RX-7. The owner was a highschool kid, his dad bought the car for him and the engine went bad. I got one hell of a deal.

$1,500 for Hinson Mount Kit, $4,400 shipped for complete 01 LS1 swap, $500 for used Hinson radiator, $60 for Wilwood MC, $40 for clutch line...$7,400
