Artemis Posted October 14, 2008 Report Share Posted October 14, 2008 Okay, you guys might think this is a little crazy but hear me out. Everyone's always talking about creating a set of custom headers for the LQ1's. But very little seems to really happen...aside from the brave few who actually make their own. Now, instead of making a custom set.... what if we just modified an existing set of headers to work with our engine? I've been looking it up, doing preliminary research, and found some headers that don't look too different from our own. I'd like to see if you guys had any opinions since you most likely know more than me. I was checking out Ebay and searched V6 headers, now there were some headers that MIGHT be able to be modified with a different flange ofcourse to work on our LQ1's. Just to name a few that I thought could work: Nissan 350Z 4th gen Nissan Maxima 98-02 Honda Accord 94-97 Ford Mustang 3.8 I know it seems a little crazy, maybe you guys can throw in some thoughts. I think it would be pretty cool to buy a header for $100-$150, mod it for $50 and bolt it on. Might not be THAT simple, but if someone could get it done for around $200 then it could give us all encouragement to do it ourselves.

slick Posted October 15, 2008 Report Share Posted October 15, 2008 Not only a different flange, but the tubing would have to be completely reworked. That, and then you need a custom crossover made as well. Unless you are a fabricator, own a welder (or have access), have access to a good bridgeport, saws, tubing, and a tubing bender, there's no way in hell your going to get headers for less than $200. In fact, I don't know a shop that would weld a set of flanges to six tubes for less than $150. There's about a day's worth of time, if they are actually doing a somewhat decent job.

digitaloutsider Posted October 15, 2008 Report Share Posted October 15, 2008 What exactly makes you think headers for a Ford, Honda or Nissan would work, exactly? Quote Link to comment Share on other sites More sharing options...
Artemis Posted October 15, 2008 Author Report Share Posted October 15, 2008 i never said they would bolt on. The premise is modifying inexpensive headers to fit on our car. I have a friend who's a welder, the flanges will not cost me much to weld on. Certainly not $150. Quote Link to comment Share on other sites More sharing options...
GP1138 Posted October 15, 2008 Report Share Posted October 15, 2008 Should I even say the "A" word? Alright, fine. There was a guy who made a set of what he called equal length headers for the LQ1. They are currently owned by 5speedZ34, and have been sitting in his garage for the past what... 2 years? Anyway, he was fairly hasty in making them, the welds looked like shit, and he had to notch the subframe to make it work, but they're there and functional. I'd say talk to them, and go from there.

Euro Posted October 15, 2008 Report Share Posted October 15, 2008 Go through all this work and have maybe what, 3 people do it along with you? Doesn't seem worth it to me. Quote Link to comment Share on other sites More sharing options...
Artemis Posted October 15, 2008 Author Report Share Posted October 15, 2008 Not planning on having some sort of group buy. Just looking for opinions. If I do get it to work, I plan on telling everyone exactly how. Thats all. Who's the guy that has a set for 2 years? Quote Link to comment Share on other sites More sharing options...

Artemis Posted October 15, 2008 Author Report Share Posted October 15, 2008 They are currently owned by 5speedZ34, and have been sitting in his garage for the past what... 2 years? haha, apparently I cant read! I've been doing a little more research. Does anyone have pictures of a fully assembled pacesetter or slp header for the L67? I've been comparing the LQ1 and L67 headers from Milzy Motorsports, they look quite similar. Obviously not exactly the same, but the front and rear manifolds are quite close. Just the collector pipe looks like it has different angles. If I could use the front and back manifolds and custom make a collector... well, this is just a start. A friend of mine sells L67 pacesetter headers, gonna see if I can get some measurements. Quote Link to comment Share on other sites More sharing options...

L67's are 90 degree V6's..........your LQ1 is a 60 degree V6..........seems to me that *might* just cause a bit of a problem Not to mention that LQ1's have an atypical port spacing AND said ports are HUGE and a goofy rectangle-like shape. Throw in the fact that 1st and 2nd gen W's have a different cradle and different firewall spacing.......................... Etc etc etc........ *I* have a better idea. Go buy another FRONT exhaust manifold for an auto trans car, flip it, mount it on the back, fab a custom crossover and mount a TURBO on that...........and continue.

I also read somewhere, now I don't know where or how much truth there is to it) the Exhaust manifolds on the LQ1 are some of the best flowing exhaust manifolds GM has ever used. Why not just get them ported & polished and get them ceramic coated. Probably still going to cost you the same as having headers made up, and who is to say the headers will do anything. At least with MY idea you would at least be improving the performance a bit... Jamie Quote Link to comment Share on other sites More sharing options...

Can anyone else verify is our stock exhaust manifolds have good flow? Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted October 15, 2008 Report Share Posted October 15, 2008 Take one to a machine shop with a flow bench? someone on 60*v6 might be more educated about this... Jamie Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted October 15, 2008 Report Share Posted October 15, 2008 Take one to a machine shop with a flow bench? someone on 60*v6 might be more educated about this... Jamie The rear manifold/collector for the LQ1 is ok, but the stock front log is FAR from being great. The reason I recomend using one for a turbo setup is because the front 91-95 auto trans manifold can simply be flipped upside-down and used on the rear............and since they are cast iron (and thus, strong/durable), they make for a RELIABLE start to turbo plumbing. And be SURE to get a well made crossover. Mandrel bends, flex sections and do NOT just hang the turbo off of the flange from the crossover...........otherwise you'll end up cracking stuff. For turbo choice, I'd recomend a T04B 60 or TO4B 62 as their compressor maps work very nicely for the LQ1's flow potential (some assumptions are made, but they work fairly well). And remember..............RESEARCH is your friend where custom turbo setups are concerned (what intercooler to use, where to route piping, where/what MAP sensor to use, what sized injectors, what fuel pump [if any], downpipe design/routing etc etc etc). Also, *I* would have an Ostrich emulator and my OWN chip burning capability and *start* with a TGP .bin file and go from there............in little baby steps at that...........don't want to spend $4K turboing the car and then pop it on your maiden drive. I mean..............in MY opinion, turbo LQ1's *ARE* the best way to go (especially for auto trannied cars......got to build the trans a little though), but they are $$$$$ and are NOT for the faint hearted. That's my 2 cents. Quote Link to comment Share on other sites More sharing options...
Artemis Posted October 15, 2008 Author Report Share Posted October 15, 2008 Found some more info from the crazy Fiero guys. Nice looking headers http://www.fiero.nl/forum/Archives/Archive-000002/HTML/20070315-1-060505.html Even nicer headers http://www.fiero.nl/forum/Archives/Archive-000001/HTML/20030531-2-027692.html If you look at the second set, I have found some headers for the 4.0L Mustang that look VERY similar. At least the front headers. http://cgi.ebay.ca/Ford-Mustang-05-06-07-1617SJT-V6-4-0-Performance-Header_W0QQitemZ160290812713QQcmdZViewItem?hash=item160290812713&_trkparms=72%3A1215|39%3A1|66%3A2|65%3A12|240%3A1318&_trksid=p3286.c0.m14 Quote Link to comment Share on other sites More sharing options...
TURBOLUMINA Posted November 24, 2008 Report Share Posted November 24, 2008 Should I even say the "A" word? Alright, fine. There was a guy who made a set of what he called equal length headers for the LQ1. They are currently owned by 5speedZ34, and have been sitting in his garage for the past what... 2 years? Anyway, he was fairly hasty in making them, the welds looked like shit, and he had to notch the subframe to make it work, but they're there and functional. I'd say talk to them, and go from there. Im assuming you are talking about me here. I built the headers. They are equal length, and the welds not being pretty means jack shit. I did it the old fashioned way called torch welding. I didnt have a tig welder at the time and rather than do a redneck mig weld job melting gobs of shit inside the primaries as im sure you probably would, i did the job right. And those shitty headers made 225 whp n/a before i went turbo, where i then managed to make over 400whp on pump gas and only 10psi. So until you can you manage to build a LQ1 car as nasty fast as i have, maybe you shouldnt knock someone elses engineering. And its drummer who has them, and he has only had the headers since september btw...... Quote Link to comment Share on other sites More sharing options...

The "A" word is Aaron, A LQ1-humper now turned fiero guy with a turbo LQ1 swap who was banned before your time. Before my time for that matter. He was not talking shit on your headers. As far as I know, there have been no pictures of your headers on this board without header wrap on them, so I don't even know how someone could talk shit besides Drummer, who I don't think would talk shit on something he has on his car now. I guess this is a perfect example of the assuming making an ass out of whomever Quote Link to comment Share on other sites More sharing options...
