I’d like to use them on my truck but I would need to have a 45 degree angle off the spark plug . Id need to go around the fuel rail . They sell all sorts of lengths stalks. The spring is the park that is harder to cut. The stalks are easy. 1 Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 26, 2023 Author Share Posted February 26, 2023 Well I’m 99% sure I’m going DBW(drive by wire) on my ITB setup. I will be swapping ecus when I get Larry Asp new injectors at the head intake. I was googling DBW pedals and I thought the 350z pedal box looked mighty similar to the 240z one. I got one to check and wow it’s close. I love when manufacturers don’t stray too far from designs. Then googling some more and freaking Etsy sells a direct mount for it! Now I need to change the pedal pad to look stock, and powder coat the housing. But it should be a very simple mod/ install. This will unlock cold starts, progressive throttles and a host of other things like torque control etc… This is all Aaron Neubauer fault for posting about Emtron ecus and their neat tuning method throttle mass flow.

DuffyMahoney Posted February 26, 2023 Author Share Posted February 26, 2023 A quick little my 240z DBW gas pedal box from a 350z. I drilled the plate to match the 240z one then ground off the pedal stop. Lines up and bolts right in! I get full pedal travel and the stock stop on the floor it’s nicely. Next is buying a stock gas pedal and cutting off the pedal plate and welding it onto this one. Then powder coat it all to match the stock black. All in all very nice and easy.

DuffyMahoney Posted February 26, 2023 Author Share Posted February 26, 2023 Next is laser cutting out the plate and hopefully just welding it on with no rod bending. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 27, 2023 Author Share Posted February 27, 2023 Should work out nicely. Getting a plate laser cut tomorrow. Then some welds and then powder coated. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted February 28, 2023 Author Share Posted February 28, 2023 Laser cut, welded, powder coated and ready to install! Clocking and bend is about perfect from stock. Stoked Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted March 1, 2023 Author Share Posted March 1, 2023 ITB DBW update. Installed, feels and looks like stock! I had the stock pedal pad copied, then laser cut. Then welded onto the 350z pedal rod. I also had the pad bent to match my stock pedal and also clocked to match. After that I got it all powder coated to match. Should work great! I can tell it’s not attached to linkage, but it still feels somewhat stock. I like how I can’t really tell it’s not stock without looking hard.

jonbill Posted March 1, 2023 Share Posted March 1, 2023 What motor unit will you put on the ITBs? I'd be interested in following to the same path to maximise power at lower rpm. Quote Link to comment Share on other sites More sharing options...

I'd be interested in following to the same path to maximise power at lower rpm. That is TBD. One idea is cutting up the LS3 throttle body. A few shops have done that with good success. It's just not a ton of room on a L series for it. The kincer one is very nice, but 2300 dollars for a 40 dollar motor and a nice housing seems far fetched to me.

DuffyMahoney Posted April 27, 2023 Author Share Posted April 27, 2023 Well my balance bar design is done. Basically i made decorative bolt on injector blanks for my vintage SK throttles. Should work awesome. The goal was to mimic what SK had in the 80s, these are my take on the original block off plates and vac plates. Next off to get cnc’d Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted May 7, 2023 Author Share Posted May 7, 2023 Rainy Sunday z project! Finally got my cable mount installed for my new cable driven ITB setup. This is a lokar cable to a stock 240z pedal with the ball end removed. Then I made a tiny bushing. Everything is snug and works as it should.

Will you have to fit a pre and post butterfly pressure sensor on every runner, so 12 sensors in total, or on just one? so only 2 sensors?

One atmospheric, then one post that is balanced between all runners. Which I will already have. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted August 9, 2023 Author Share Posted August 9, 2023 Well I ended up selling my SKs. I am going EFI hardware pro throttles and a vintage FET V1 intake. The FET has about a perfect injector angle and should spray fuel directly down the middle of the runners. The only real issue is they have huge ports at the head, so I will be welding them up and matching to my head. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted August 9, 2023 Author Share Posted August 9, 2023 I got the idea for the angle here. This is a Fet v2 or v3. The issue with those intakes is the middle carb/ throttle is higher. So you can't run a solid fuel rail. Also this version of the FET has 30mm runners at the head. So lots of porting is needed. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted August 9, 2023 Author Share Posted August 9, 2023 Also working on a new coil bracket, this one has a built in angle for the boots not to be bent so much. It was cut on a 5axis cnc. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted August 9, 2023 Author Share Posted August 9, 2023 I am working on the stalks now, 3D printing and test fitting how the stock springs will work. The goal is cheaper and rigid like the stalk coils, I plan to make and sell a few of the brackets. Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted August 9, 2023 Author Share Posted August 9, 2023 Also I got my taper bore pro EFI hardware 45mm throttle bodies! They are cnc cut and very pretty, the have the most shallow injector angle I could find, and I love the bearings, 8mm shafts and butterfly angle. Sadly they were damaged in shipping, so back to waiting. Quote Link to comment Share on other sites More sharing options...
