red13 Posted January 14, 2018 Report Share Posted January 14, 2018 Are you takimg into account short runners for the 620s? Not sure if the other variants habe the brake,booster issue. 1 Quote Link to comment
G-Duax Posted January 14, 2018 Report Share Posted January 14, 2018 Since EFI, come out, and up, like a lot of modern manifolds are. 1 Quote Link to comment
distributorguy Posted January 15, 2018 Report Share Posted January 15, 2018 Do a write up on putting together an EFI kit for $900 in a thread for those that will not buy my manifold. I said for $900 you can buy new DCOE manifolds, throttle bodies, and fuel rails. From Pierce and off Ebay and other places. You don't offer an EFI kit for $900 nor did I mention one. The only advantage I see for this setup is installing a turbo. Not my cup of tea, and hopefully it fits around the master cylinder without impeding airflow. Its a nice design for those who need it. Locally we have a casting shop that's relatively inexpensive. It costs about $300 to have triple throttle bodies cast - 2 pieces each. Then they need to be machined. I run them on my flathead Ford - and they share a base design with the Weber downdraft. In the long run its always cheaper to make casting tools than to individually machine each piece. It minimizes material costs and reduces machine time. Plus you can 3D print casting cores for low quantities. The payoff is likely at around 20 units given the size of the components. 1 Quote Link to comment

I appreciate the input but this isn’t targeted at the budget drivers. I get enough emails from the budget guys and you sound like the guy they should go to instead of me. I don’t disagree that casting is cost effective in quantities, but I’m not interested in casting anything. Thanks 5 Quote Link to comment

Thanks typically machines dont cast and casters dont machine a machined manifold will be bad ass 2 Quote Link to comment
scooter Posted January 23, 2018 Report Share Posted January 23, 2018 This will be a bitchin manifold for the die hard L series guys that wanna fuck with everyone else and still gloat.. Even then most people that see it wouldn't think it's some cnc badass custom thing... fucking kids these days don't even know what webers are.. If I hear “nice ITB's“ from some punk at cars and coffee one more time I'm gonna lose my shit 2 Quote Link to comment

Stoffregen Motorsports Posted January 23, 2018 Report Share Posted January 23, 2018 I think what you're doing is very cool and I wouldn't worry about having application specific parts. If they make horsepower, and guys want them to fit in their cars/ trucks, they'll figure out how to make it fit. Example - If it doesn't fit in a 620, I would take that as an opportunity to redesign the brake/clutch pedal layout to get rid of that stupid brake booster spacer. Move the clutch pedal/master over towards the door post and mount the brake booster right to the firewall. Clean up the appearance of the engine bay and get to run a really cool intake. Two birds with one stone...well, maybe not one stone. 3 Quote Link to comment

I really wanna see a full on hardcore l series turbo efi build... cnc intake, full build lz23 with forged everything.. big ass borg warner turbo.... come on 500hp 4 cylinder L series haha 2 Quote Link to comment

scooter Posted February 3, 2018 Report Share Posted February 3, 2018 I like what your making. Another thing too is just making dcoe manifolds. From what I've seen the only twin weber manifold available new is the cannon one. My experiences with mine have been rather meh. I had to port the shit out of it and now it is paper thin. The nitrous nozzles are barely held in from anything and I'm scared to weld bungs on as its thin and cast aluminum. If you came up with a large runner Short length manifold to bolt up side drafts id be into that too. At this point at this kind of cost Is it even worth running 45 or larger carbs when you can just go efi with the previously thought up manifold.... Hmmm.. Quote Link to comment

Xnke Posted February 17, 2018 Report Share Posted February 17, 2018 Just as an aside, I made a run of 4 EFI L20B manifolds last year, sold one to a member here and used one on a dyno mule later. Even at 450$-ish I only sold the one here, one locally, and one was kept for dyno testing. The last one is still sitting here waiting to be assembled and sold. Ratsun isn't the place to try and sell new parts, try over on the 510realm. 5 Quote Link to comment

Better than Cannon anyway... https://www.piercemanifolds.com/product_p/MT-0037-C.html I have a RallySport that is badass. It raises the carbs up higher for a straighter shot at the valves, and way better brake master clearance. PM me if interested Sorry for the threadjack Matt. ^_^ . 1 Quote Link to comment

distributorguy Posted March 9, 2018 Report Share Posted March 9, 2018 Sorry for the hijack as well. Scooter, those are the ones I run on the race truck. They needed welding to fill a dead spot inside, but I was able to port them for 50mm carbs. They're basic 45 DCOE manifolds. The carbs did NOT fit with the brake booster in place. 1 Quote Link to comment
