MrFurious Posted August 20, 2006 Share Posted August 20, 2006 Spent the last two nights going through pages and pages of old posts here, but I have yet to find the answer to a simple question (that or I got a severe case of information overload and totally missed it). Does JTR offer a kit specifically for the LS engines, or do they only have the kit for the LT1 and earlier SBC's? No info on JTR's site specifying if they do or not, but in the course of my travels here I could have swarn I saw where someone mentioned using a JTR kit to swap in a LS motor. I hate to call them knowing I'm not yet ready to order anything, so I'm hoping someone here can give me a definite answer. If not I'll go with the JCI kit, but some of their additional componenets are a little pricey IMO. Quote Link to comment Share on other sites More sharing options...
jbk240z Posted August 20, 2006 Share Posted August 20, 2006 JTR does not have a mount kit for the LS1, although I wish they would, as the JCI stuff is way over priced IMO. They do sell headers that work with the JCI mounts. Quote Link to comment Share on other sites More sharing options...
MrFurious Posted August 20, 2006 Author Share Posted August 20, 2006 So is JCI the only game in town for LS engine swaps right now? Quote Link to comment Share on other sites More sharing options...
smoorenc Posted August 20, 2006 Share Posted August 20, 2006 Are the JTR headers better than the JCI headers or is just the cost? Quote Link to comment Share on other sites More sharing options...
SSflyer Posted August 20, 2006 Share Posted August 20, 2006 Check out Jeromio's web page. If you can/want to make your own mounts, he's got a good way to do it. I think the address is http://www.jeromio.com Quote Link to comment Share on other sites More sharing options...

Pop N Wood Posted August 21, 2006 Share Posted August 21, 2006 the JTR headers have bigger diameter primary tubes than the JCI ones. Actually I am not sure why anyone would buy the JCI headers. The JCI mount kit is suppose to be pretty good. Seem like a lot of money until you realize how much work it is to engineer your own. Besides, not everyone has the tools and patience to do it on their own. There is something to be said for getting the job done. Making your own cross member is not that difficult. http://forums.hybridz.org/showthread.php?t=105868 Just a lot more trial and error involved.

zed240au Posted August 21, 2006 Share Posted August 21, 2006 After installing my nissan v8 some 16 years ago I decided to do the ls1 conversion now at first i was like most people i thought that sounds a lot money for the Jci kit but soon as i started thinking it through i decided it was cheap i mean the engineering is all done u know its gonna fit first time no measureing making it trying it then cursing it changing it like so many things i did with the nissan v8 My time to me now is way to restricted to muck around trying it mutiple times to make it fit I hate to think how many hours i spent making my extractors for the nissan So to me the JCI kit ant cheap but think how many hours you loose trying to do it your self Mick Quote Link to comment Share on other sites More sharing options...
Phantom Posted August 21, 2006 Share Posted August 21, 2006 Having lived through the 11 months that JCI mucked around with my car developing the kit I can confirm that it is, in deed, well engineered. A lot of thought and trial-and-error went into each componenet to ensure that it not only did what it was supposed to do but didn't cause a problem somewhere else. Four years and 25,000+ miles now and everything is still solid. Quote Link to comment Share on other sites More sharing options...
v8260 Posted October 1, 2006 Share Posted October 1, 2006 I was lookin at his order sheet. WHy does he need the vin #? Quote Link to comment Share on other sites More sharing options...
MikeJTR Posted October 1, 2006 Share Posted October 1, 2006 This is just a shameless plug for JTR. The JCI LS1 kit is a good mounting kit. JTR, however, does offer headers, an aluminum radiator, and air cleaner ducting that will work with the LS1 Z. http://www.jagsthatrun.com/Datsun-Z-LS1-V8_Order.html Quote Link to comment Share on other sites More sharing options...
Kbhead Posted December 18, 2006 Share Posted December 18, 2006 So which Headers from JTR is everyone using, they sell two types for the Z: 1) Block Hugger - 1 5/8" Primary tubes, 2.5" collector-Ceramic Coated (DAT-402C) $300 Can't tell if these fit on the LSx engines or the LT1/350 2) LS1 Shorty Headers - 1 3/4" Primary tubes, 3" collector-Ceramic Coated (DAT-405C) $475 These ones are advertised as being able to fit with John's Cars mounts. I'm assuming #2 is the one people are using but hoping they both work as $475 seems a bit high for short headers. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted December 18, 2006 Share Posted December 18, 2006 JTR has separate pages for the LS1 stuff and the generation 1 and 2 SBC stuff For LS1's, #DAT-405P is the plain, uncoated version and #DAT-405C is the ceramic coated version.

Paz8 Posted December 18, 2006 Share Posted December 18, 2006 I know that the JTR headers for the first gen SBC are manufactured by Sanderson, very good quaility stuff, Sanderson has been in the business a very long time. Quote Link to comment Share on other sites More sharing options...
m1noel Posted December 18, 2006 Share Posted December 18, 2006 I used the JCI kit and for a first timer it went really well. I also used the coated headers from JTR which were a little pricey but very nice, and with all the $$ I have put into this car the little extra for the coated Sanderson's doesn't seem like that much. I also used the JTR radiator but got pretty much every thing else from John's. Mike Quote Link to comment Share on other sites More sharing options...
