Yes. Big in the JDM scene the world over for years now. Big bore angled exit, burnt slash tip.

Sounds like doing it is a royal PITA though. From what I've read the steering rack is located in the wrong place so it has to be relocated which means customizing all your steering gear. Not too mention that's a hell of a torque upgrade. You probably have to get a beefier rear end too so you don't blow it up. Sounds like you already agree with me about displacement if you're thinking of doing this. I think you'd be better off buying a 2004 GTO then putting the time and effort into the Nissan though. Sounds like a challenging project nonetheless.

No i am not about only autocross and road racing.

Also don't try to google up about a swap and then think you know about it.

The stock KA24DE is more than capable of putting out impressive numbers easily and streetable....plus any of the RB 6 cylinder drop-ins like the RB26DETT from the Skyline.

The main reason the LS1 is an option is at about 100k I'd need to rebuild my bottom end to do it right...or just find an LS1...swap it in and be at about equal power plus better balance. It would be the hardest swap out of the options I am looking at.

Just dropping the LS1 in puts my car in the 12's with better balance than stock.

It's not a look really...the angled muffler is a straighter shot out...the burnt tip is used outside JDM's...just hides soot more than anything.

The tip is not that big of a bore considering the exhaust is 80mm (over 3" throughout).

Meh, If I never see another DTM style twin upswept exhaust on a 3 series I will be happy.

Apparently Alkemyst knows it all lol. So you know all about swapping LS engines into a Nissan then. How'd you learn it? Do one yourself already? Help a friend do one? Or did you just look it up on the internet like I just did? Do you have to move the steering rack to get it in there? If so where do you mount it? I was not trying to be a prick but was seriously interested in how you would go about it. Why don't you relax and stop being so defensive.

Do you replace the whole drive train including the rear diff with beefier axles? The LS1 and LS2 are both torque monsters. I'd expect they'd shred the stock rear end on a Nissan after bunch of hard launches, even quicker if you mod the motor. I'm no expert on how to drop one of these in a Nissan, but you piqued my interest so I started reading about it. Also I've been looking at buying a GTO like AdamK's so I'm familiar with the specs on the cars as well as many of the issues those cars have. I've been lurking the gtoforum.com and ls2gto.com sites for nearly a year now reading about the new Goats and watching prices.

As far as the LS1 goes, they're pretty solid motors with not too many issues. The LS2's I've been reading about issues with oil consumption. Some of the LS2's of the members of those boards have been burning upwards of a quart of oil between oil changes. So something you may want to think about when you go to get a motor or at the very least watch closely if and when you put one in. I've also read that they tend to pull a lot of oil through the PCV systems and many of the members have installed catch cans and filtration units to keep this stuff from being sent back through your intake.

I am active in the Nissan community down here. I have seen the swaps and have been a part of some. Not to mention I have done a ton to my own car.

The stock rear in the 240sx is the R200. It can take a lot of power as the same basic setup is used through out the Z and skyline lineup.

The thread I was reading the guy was talking about cutting up the firewall to get an LS1 in the car. That sounded a bit drastic to me. I'm not sure he knew what he was talking about. Do those engines fit in the bay or do you have to chop the car up to get it in? The engine crossmember and mounts would definitely need to be custom jobs. My guess is you grab the engine, transmission, motor mounts, tranny mounts and drive shaft off a donor car and then start welding. Assuming it all fits under the hood without jacking around with the steering box of course. Probably relocate the battery to the trunk so that there is room for the intake pipe.

it's really not about visually attractive. You want that get some spinners and call it a day. Also you don't see much of it from looking at the car from where one would be standing. The angle in my video is from under the car...the car has only 4-5" of ground clearance.

The exhaust is angled and a canister by design. The fart cans are copied usually 150mm+ openings with a 1.5" inlet pipe that bolts on a stock exhaust. People talk that it causes an extra bend in the system and all that, but it doesn't...it's a lot straighter through. You could make a straighter shot back under the control arm, but at that point you would not be clearing much even at stock ride height. For the most part this exhaust tucks right along the underbody...only the rear resonator hangs about 1" lower than the stock piping and will rub lightly over the speed mountains we have here.

This is a light weight (25lbs) setup designed for max power while being noise compliant (the turbo needs to be in place for that).

The piping is 80mm (~3.15") all the way through.

For every thread swap the right way, there is about 100 the wrong way out there.

AFAIK the LS1 swap doesn't require battery relocation. Turbos usually don't either unless running a FMIC.

Clearancing the firewall is not usually a big deal. I had to clearance my steering knuckle to fit my header.

It's a great setup, 5Zigen makes great stuff. 80mm on an engine that size could definitely use some forced induction. Can't wait to hear about the next step in your project!

What brand is it? Basically just a cat back with what appears to be a glass pack but I'd imagine it's not. I gutted the stock system on my truck and put on a flowmaster because it gave me the balance of flow and noise that I wanted to work with my bolt on supercharger - otherwise I would have just gone with a Spintech.

seriously, are you just trolling or retarded? I mention the EXACT exhaust in the video.

5Zigen ProRacer A-Spec 80mm.

That's a translation issue between the US and Japanese markets.

tailend = tips (inconel)

care to elaborate? Still a great exhaust. The Inconel on the tip keeps oxidation and corrosion WAY down. The only step up from this exhaust is titanium at double the cost.

I would lose another 10-15lbs of exhaust wieght depending how thin the walls were, but at 25lbs now it's a very lightweight and street worthy one.

Hm, I guess that would have helped. Work proxy prohibits youtube, so I have to filter it through a homegrown app that just grabs the youtube video stream and nothing else, so I didn't see the youtube page/title/comments/etc. Not that it really justifies you being a jackass to a simple question, I can still sympathize with being irritated with questions that should easily answer themselves.

The tip is the coldest part of the exhaust system, which means that if the exhaust isn't going to rust upstream (stainless), it won't rust downstream (tip).

oxidation you missed and yes there would be more upstream.

What are you driving anyway? You seem to hate anything on the road.

Just the tip and muffler's endcap is made of inconel 600, right? The rest is stainless, 409 piping and 304 muffler.

Main exhaust: SUS409 1.2MM all stainless steel
Tailend (not just tail pipe): SUS304 + INCONEL 600

That's a translation issue between the US and Japanese markets.

tailend = tips (inconel)
What a waste.

care to elaborate? Still a great exhaust. The Inconel on the tip keeps oxidation and corrosion WAY down. The only step up from this exhaust is titanium at double the cost.
The tip is the coldest part of the exhaust system, which means that if the exhaust isn't going to rust upstream (stainless), it won't rust downstream (tip).

oxidation you missed and yes there would be more upstream.

What are you driving anyway? You seem to hate anything on the road.
Rust is oxidation.
