A really informative and well presented video - as always. I like your style of presentation; very clear, to the point and NO waffling! Brilliant. Those injector ports were really clean - I had to clear mine out with cotton buds etc!! Keep up the great work.
Thanks Phil, appreciate your kind words! Yeah they weren't too bad to be honest, I may have given them a quick wipe but that's all. Another advantage of having sub 30k miles I guess!
I really appreciate this video!! I have an Exocet with a 1999 Miata 1.8l and I need to replace my fuel injectors. I was a bit hesitant because of the upper intake manifold but this gave me confidence!!! Thank you sir!
Nice job, literally just been watching this series every night then I was like when did this finish why’s there no final video or the sc fitted then just realised this was 10 days ago! Waiting!
Just getting into the world of proper car modifications and standalone ECUs, why wouldn't you need a MAF sensor with a standalone ECU? How do they know the amount of air coming into the engine? Edit - Just read up that it's a mix of engine RPM and MAP data, in this case, how does the supercharger affect the fueling algorithm? At least it's still RPM dependent like it would be with the engine creating flow, but presumably has a different curve to it?
Yes no MAF required as you will run a vacuum line from the intake to the ECU for the MAP reference. When you supercharge or turbo charge you need to map the car (essentially fueling and ignition timing) for above atmospheric pressure.. i.e in boost.
@@ziyakucuk4082 oh I thought you meant using the injectors out of one. Never driven a 626 but I have a lot of time Mazda. Unfortunately they seem to get eclipsed by Toyota/Nissan etc, but Mazda make some cracking cars.
Yeah never seen anything like it. There's a few different types of inlet they fitted over the years. One version has a set of butterflies inside that open up at higher RPM (VICS I think they called it). I will give Mazde their due - they come up with some weird stuff! I don't think they did velocity stacks though 🤣
It was to improve low down tourqe without compromising the top end So you had a long branch intake up until midway and then the short runners would open later on Not sure actually how effective it was ft/lbs wise
That's it. People have tested a VICS MX5 on the dyno and from what I remember it did improve low down torque. VVT did it better though so they obviously canned it when that came along

Yeah not finished just yet sorry! Not far off though - hopefully early 2022 👍🏻 Working on next video now should be out at the weekend. Thanks!
Great video,did you need engine internals mods?
So, no need for a remap after new/bigger injectors?
I am doing the exact same set up you are you willing to share that MAP? I have the exact same things you are running and cant find a remote tunner😭

Do you not need to upgrade the fuel pump and also get a pressure reference fuel pressure regulator?
No, & no. Not with this setup.
very interesting. Wait to see more.
More to come!
@@FastRust i follow, i would like to try with a pinto injection and a M65 eaton. :)
Would you recommend Mazda 626? 1994
No absolutely not, my ex's parents had one of them!! 🤣
@@FastRust thanks
I've not heard of them being used in an MX5. Thats not to say you couldn't though. What cc/min are they?
@@FastRust mx5 is expensive here

Interesting that split manifold
Perhaps a cheeky velocity stack install at a later date ?

@@FastRust oh like bwm Disa duel length runners
Is it to help with air speed or something?? I think that's why they did it.. but then they stopped doing it by my year MX5 and went to VVT instead!
