Ryan Merrill Posted June 12, 2016 Share Posted June 12, 2016 Pretty close but they fit. There is about 3/8" between the headers and the strut tower. 1 3/4 primaries are a little big and the 3" vband collector is definitely too big to be optimal in any car under 800 HP. At 160 bucks US, they meet my budget and I will be using them. The metal is a little think for my liking but it should hold twin t3's no problems. I will be going twin T4's so I may make a support bracket for the turbo's. The engine is a 5.3 aluminum L33 Gen IV, LS1 intake, upgraded cam, springs, and pushrods.

Stock Car Mafia Posted June 13, 2016 Share Posted June 13, 2016 Are you relocating your coils? It looks like they wouldn't fit on the stock brackets on the pass. side valve cover. I will have to say, this really makes me want to sell my longtubes this winter and go with a turbo build! Quote Link to comment Share on other sites More sharing options...
Ryan Merrill Posted June 14, 2016 Author Share Posted June 14, 2016 Yes the headers touch the brackets on one size. NIce mustang in the sig, I have a 93 fox with a termie swap Quote Link to comment Share on other sites More sharing options...
nathaninwa Posted June 14, 2016 Share Posted June 14, 2016 I ran those headers last year. I made a new coil mount and moved them higher up the cover. I did have to run custom length plug wires with a 45* end and still used some fiberglass boost to protect the wires, especially the forward cylnders Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted June 15, 2016 Share Posted June 15, 2016 Any chance they could be flipped to install up-side-down? Quote Link to comment Share on other sites More sharing options...
nathaninwa Posted June 15, 2016 Share Posted June 15, 2016 (edited) I remember the collector hitting the block and huge potential for accessories to fit up, unless something custom was fabbed. I ran mine up and forward after lengthening the forward cylinders runner for more of an equal length setup And they were 1-3/4 inside header so they should be advertised 1-7/8 Edited June 15, 2016 by nathaninwa Quote Link to comment Share on other sites More sharing options...
zspeed22 Posted June 16, 2016 Share Posted June 16, 2016 Any chance they could be flipped to install up-side-down? They defiantly do fit with the dirty dingo mounts upside down. The alternator will have to be moved up top to clear. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted June 17, 2016 Share Posted June 17, 2016 Zspeed22-do they clear the steering rod too? How is plug wire clearance? Quote Link to comment Share on other sites More sharing options...
zspeed22 Posted June 20, 2016 Share Posted June 20, 2016 Zspeed22-do they clear the steering rod too? How is plug wire clearance? They do clear the steering rod without an issue. Also plug wire clearance is not an issue either because of how the tubing is spaced. Honestly they two issues I have with these are the giant collector vbands, and how far forward they put the vbands. Those are two things I can easily work with.

stony Posted June 21, 2016 Share Posted June 21, 2016 These are the 240sx Cxracing ls swap headers. I flipped them and used LSsimple alternator brackets putting it low on the passenger side. I had to use some 90 degree plug and coil boots. but overall the fit is good. will be it SOB changing plugs though. they may fit better with the dingo mounts and turned over like they are supposed to be.

I just dont know how to mount the alt to clear the hood. Passenger side will have issues with the down pipe. Truck mount for high alt on drivers side hit the hood. The low mount way also creates issues with exhaust path. I would rather go under the header than over. IMO. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted August 2, 2016 Share Posted August 2, 2016 High mount with hood blister? Mount it on driveshaft? Quote Link to comment Share on other sites More sharing options...

This is what I did for the alternator with the stock Fbody mount. I have seen a few people use this method in the past. Quote Link to comment Share on other sites More sharing options...
The Infidel Posted August 4, 2016 Share Posted August 4, 2016 This is what I did for the alternator with the stock Fbody mount.

zspeed22 Posted August 4, 2016 Share Posted August 4, 2016 Nice, I might do this but shorten the length that the vbands stick out. I did end up having to mill the back of the Alternator when I did this so the thickness of the bracket coming off the head did not change angles on anything. I also planned on pie cutting them down to a smaller vband. If you notice they would hit the factory heater bypass lines on the water pump. You could do a few things with that. I decided to cut the pump mill the center out and cap it. This way it can internally bypass. Quote Link to comment Share on other sites More sharing options...

I also have a mill, so Im not to worried about clearances. Quote Link to comment Share on other sites More sharing options...

Ryan Merrill Posted September 4, 2016 Author Share Posted September 4, 2016 Looks like the dirty dingo mound sits at least an inch lower than the cx racing ones. Quote Link to comment Share on other sites More sharing options...
