As you guys may have seen on social media we are almost finished putting the final touches, for a custom intake manifold for the l-series. We thought it only be fair to post here as well. Here are the details... Finally a Beautifully Tig welded Aluminum Intake Manifold For the L-Series motors. With a choice of 75/ 90mm Throttle body and Fuel Rail. We have been researching and devoloping this behind the scenes it is a very well thought out piece that has function and form combined.

Hey guys, I'm nearing my wits end with my car (76 280z with a 78 engine n42head n42block). The P.O seems to have deleted all of the emissions and most of the vacuum lines (egr, pcv, bcdd all blocked off). I am having this issue now where i have back firing from the intake at idle (dozen or so per minute) and after warm backfiring out the exhaust and loss of power while on the road. Additionally, the car seems to start at a very high idle. The fuel system is all custom cell with -AN set up (pressure great), valves adjusted to spec, injectors rebuilt with new gaskets, pintels, screens ect, Vacuum was checked and rechecked including with carb cleaner trick. Timing checked, temp senor replaced, all connectors replaced with new, all new plugs wires cap and rotor, new coil with internal regulator (external resistor bypassed), AFM checked for any possible signs of wear or anything, shows nothing looks great. TPS looks good, engages when suppose to. I am obsessive and have done tons of research and I cant seem to figure this out. Can anyone save this Z from being driven into a lake due to frustration? Thanks!

I put this in the "turbo" section cus I didn't see any other appropriate place, but it probably applies to the turbo somehow. I have a 1978 280z with an '82 L28ET engine. It is stock everything except for an added oil cooler. I currently have a SUPER DIRTY K&N air filter that sits in front of my radiator via some custom piping. I think the previous owner put this on in 2004 and hasn't changed it since, so I decided I would just get a new one rather than try to clean it (see below). I found the current filter online: https://www.knfilters.com/search/product.aspx?prod=RE-0910 However, I found a very similar but slightly larger filter below it: https://www.knfilters.com/search/product.aspx?prod=RE-0810 The second filter is about an inch longer and an inch wider at the base. However, it will definitely fit in the current space, so it would be very easy to swap to this size. Is it worth it to buy the slightly bigger size? Are there performance benefits/downsides, or will I not even notice this small of a difference?

I am savign up to get an engine to drop in my 73 240z. At first i wanted an ls1 to drop in, but i am now leaning toward getting an lq4. that being siad, does anyone have experice with this swap, knowledge about crucial elements i will need to know. first question being how hard is it to swap an ls6 intake onto the lq4. SHould i consider getting a Fast intake instead of an ls6 intake? will the fast intake fit under a stock hood? if so, what size do i need to get. also what other stuff is intailed in the swap?i hve been doing researh and have bits and pieces of informaton, but am still a little confused on the whole swap i am planning on pairing this with a t56 tranny. any info will help. please... i need help

Hello there z people: I was replacing the manifold gasket, and remembered some very nice pictures of shaved and polished intakes you have around here, pretty clean works, so i couldn't resist imagining it on my z he he! So i went crazy with a hacksaw on it and cut the egr, pcv, cold start, etc... then cut sheet aluminum pieces out of the blades of an old v8 fan i had lying around and welded them in place with a tic welder. the intake started to look nicer and so i followed with the next step, ...polishing it..... THATS WHERE THE NIGHTMARE BEGINS!! LOL i been polishing the thing for almost 2 weeks and im nowhere close to the finishes i seen here! Hands down to all those z lads who did this themselves! they have my deepest respect Well, here are a couple pictures of the intake so far: Every tip and advice is well recieved, CHEERS!
