Hey guys, its been asked on this forum about long tube headers for our LSx powered S30's several times.
There are those that have the skill and have successfully made their own, but don't seem to want to reproduce them for profit. Due to the frequent questions on the subject to myself, Hybridz, LS1Tech, etc I have decided that if there is enough interest (5 or more sets) I will have a prototype set built and have them copied/reproduced for resale. These will be made of stainless steel with 1/2" header flanges, 1 7/8" primaries, 3" collectors, O2 bungs in each collector, and use a V-band for the collectors (leak proof). These will offer excellent spark plug wire clearence and well as 'hugging' pretty close to the floor for maximum ground clearence without causing carpet to burn or shoes to melt. These will be used with the JCI LSx mounting kit btw.
Long tube headers will make AT LEAST 20+ rwhp more that the current aftermarket choices available which aren't much better than stock manifolds IMHO. Many folks are limited to smaller cam choices due to the lack of long tube headers available. Of course being made from stainless steel is a nice bonus too.
If this goes according to plan, headpipes with 'H' or 'X' pipes in 2.5" diameter (also in stainless steel) will also be offered. The headpipes will end just in front of the forward diff crossmember allowing the customer the choice of continuing with dual exhaust (one on each side with something than a stock S30 gas tank), or merging into a single pipe for a stock location muffler. These will include a manual cutout feature as well. These will fit both 4L60e and T-56 transmissions (may need a prototype car for the T-56 fitment). The headpipes will run about $250 with the cutouts installed and sold with or without the purchase of a set headers.
I am sure everyone is wondering the big question...how much for the headers? It will all depend on my header suppler on what the cost is going to be per set to reproduce them. I don't have an exact figure....yet. What I can tell you is they will be AT LEAST $500+ a pair, but shouldn't be more than $750 per pair (waiting to hear back).
I know there has been alot of folks that promise the moon and the stars (with headers and other things) and nothing ever comes from it. Those who know me personally and/or professionally know that I am not the sort to NOT follow-through on a project, especially when it comes to customers.
Lastly, since I am just gauging interest at this time, I am NOT accepting money/deposits. When I have a prototype set completed and a final cost for production sets, then I will start collecting deposits/payments.
So LSx S30 guys, what do you think?
Thanks for reading!!
