Hi my Name is jonny i am 23 yrs old and want to boost my mx5. It's a low Budget daily but also a driftcar.
I allready have a walbro 255lph pump installed with a teflon/stainless steel hose to the fuel rail (sorry for missing some words, my english isnt perfect!)
I have a selfmade turbo manifold and an brand New ebay turbo with Internal wastegate and want to go for 5-7psi. I have an ebay FPR and Stock internals. But i also have some Stock 440cc internals from my jspec supra that i dont need anymore. Maybe they fit?! Have Not tested yet.
Now the point where everyone's gonna hate me..
I really dont want to afford a megasquirt for 1000€(1200$) because i need like 6000 for a New gearbox for my supra.
So my plan is to raise up fuel Pressure to the Maximum
what's the max i can go for? then take the aem wideband+afr from my supra and Put it into the miata to make a "good" afr Setup under boost just by regulating the fuel pressure. I know it won't idle well but that does Not really matter to me. After finding a Setup i can Put back the wideband to supra and just drive arround with the mx5.
That's all stuff i have at home so would be the cheapest for me. But if i have to go for a FMU i could also buy. But in germany i can only find cheap ones in 1:3 ..
Peace jonny!
Some pictures of my cars will be uploaded soon

You can buy a rusefi for Euro 300. Not much more than all that fuel-vodoo and much better for your engine.

We don't like you. Go away and be a ricer idiot somewhere else.

 

Saw that one coming a mile away lol

 

Priorities lol. Money has to be spend on race car so daily car can only have a low Budget turbo setup.
If i was going for a FMU what raising range should it be? 1:12 , 1:14,..?

 

Miata does not look healthy, Supra does not have an air filter. It too will be unhealthy soon.

 

Dude wtf it's a Drift car and the Engine is healthy. 13-13,5 bar on every clindre should be good enough.
And i just took the air Filter from my supra away for the Photo.

 

Poor supra

 

Coffee looks done right. The rest, not so much.

 

his coffee looks nasty and terrible, like his cars.

 

Poor dude.. he just came to show us his cool home made stuff. well, you came to the wrong spot. Aint got no room for janky **** around here.

 

i'd go for an 1:8 FPR. Regarding the injectors: you only really need a bigger injector on cylinder #4, because it runs the hottest on an MX-5

Post some drift videos!

 

Yeah, don't do a coolant re-route, E-cool that baby.

 

hahaha!

Putting a larger injector on one cylinder LOLOL

I'm laughing so hard out loud!

Yeah. Dont do that lol

I just cant believe I read that.

 

lesson learned here- If you are going to drift and participate on this site, you better have your act together. Franken fenders wont make friends around MT.

 

I guess if he had spent the time researching on this site instead of asking to be spoon fed about how to get his whacky band-aid setup to work, he'd have known where the MT crew stands in regard to drifting and whacky band-aid setups.

 

Wilkommen to the forum.

Drifting is considered a plague here. Our cars have a low polar moment of inertia and make terrible drift cars. That is why you wreck all the time. It's not you it's the car. It's why Miatas make really good track cars.

Supras are much better for drifting because of the location of the weight and the wheelbase. Drift that.

ECUs do not cost 1000 euros. There are other options. FPR is not a good option. You will blow your engine.

Welcome und viel gluck!

 

1:30, ideally. Gotta take into consideration the pressure differential across injectors.

 

Got it together today. Thanks for usefull answers, no comment to the useless ones
