hey guys iv been looking around lots of different mx5 forums and trying to decide and work out parts list to build a turbo mx5. car will manly be used for daily driving but will be also used on track would like to first run the car at 200whp to get use to power and make sure everything is running fine but I know I will push the power up quit quickly stopping somewhere just south of 400whp

so far I have decided on a BP engine
p&p head
supertech forged pistons and rods
megasquirt stand alone
t3/t4 .50A/R (already have brand new one sitting in box)
and id also like a lsd

now I have read a lot of people are running 550cc injectors for anywhere ranging from 200-350whp is that right? also will fuel pump and radiator need to be upgraded?

does anyone have recommendations on intercooler?

also what else will I need for this set up to run/ run reliably

sorry if this is the millionth time answering these questions

We yell at people all the time for this.

Do you need us to build your car too?

I know the search button is my friend. as I said I have been looking around the forums and yes my questions get partially answered but always under different set ups. so I thought it would be better to ask about my specific situation before I go blow all my money or an engine. once again sorry for newb questions

Lets look at it this way.

If you're going to track the car, why not just get everything, and the best of the best?
Or maybe just skimp out on parts so that maybe you'll blow the engine, then send parts down the line into your expensive turbo killing that too...

You're asking if the radiator needs to be upgraded for 400whp.... Come on man...

boundbyhope

it would very rarely used on the track maybe 6 times a year other than that it will be a daily. I don't mind spending money to build the engine right I want to get at least 100,000km out of it pushing it abit. iv also read that the gearbox wont last long over 250whp would swapping in a 6speed handle up to 400whp

Your specific situation is not special. Go look at what other turbo track cars do, then do that.

400whp track cars with BP engines? That are also a daily driver? Because it is your only car? Seriously, are you trolling, just that fuckiing stupid, or just too damn lazy to have looked at all of the hundreds of reasons that won't ever happen?

Oh, only maybe six track days a year? Yeah, that's not worth upgrading your radiator over. Probably not your brakes either.

400whp on the track and also a daily? It won't. Ever.

aftermarket damper, billet oil pump, ARP everything, MBSP, braced manifold and a welding guy on speed-dial, v-band everything, inconel everything else, reroute, e85 or very careful tuning, a pile of 6 speeds and finally a new block in a few years

Based on the initial statement are you located in the US or another country? I say that because people here rarely refer to it as an MX5. It may affect your part availability and you may not have some of the cost-effective options that we have in the US.

I live in Australia. so every second car I pull up against at the lights is a 400whp LS1 commodore and the odd 600whp commodore GTS so I would love to be able to fly past them and see the look on there faces. im a panel beater buy trade so welding is no problem because I want this car on the street I will be running coilovers along with bigger callipers rotors and brake booster all of this put to the ground buy 10" rims running 245's on the rear and 8" rims on the front running something like a 225 or 215.

Hey, I've got an idea. Let's build a turbo setup around a turbocharger that I already have laying around, because well, let's just face it: "Free" is better than "functional" any day of the week!!

Hey, dumbass, have you ever driven a 250whp Miata? That **** is spooky fast. You have no ******* clue what bag of worms you're going to pour all over your naked self trying to put "just south of 400hp" to the ground.

By the time your car is capable of making 400hp, the cost of buying a brand new turbocharger appropriately sized to your application is going to be a few pennies in the fountain. A 450hp capable unit is not the same as a 400hp capable unit on your tiny *** 1.8L Engine. On a 400hp tune, your 450hp turbo will be dreadfully slower than a 400hp turbo would have been all ******* day.

I'm going to help you out just a little bit, because I'm a nice guy and all. I'm going to give you some hints for your 400whp setup, just so you can almost begin to comprehend just how deep the rabbit hole goes. At 400whp you will not be using a mazda driveshaft...or a mazda differential...or mazda axles...and probably not even a mazda transmission...and you're not going to pay Honda prices for the equipment you'll use to replace those parts.

You're not in a "specific situation" that you get to ask about. You're in the "every other ******* newb" situation.

What the **** is the deal with big "rims" on the front and little "rims" on the back? Is that some sort of australian fad or something? I think we may have went through that in the '90s. It's overrated. Unless you never plan on using the steering wheel to actually turn the car - just go straight I suppose.

Do you even know what a "rim" is? Here, I'll show you:



I don't know, were you maybe planning on floating on air? Or were you seriously hoping that these things would be bound to the car by hope?

iv driven afew 600whp+ commodores running 315 tires that barley keep traction I was thinking smaller rims on the front as modification to the inner skirt would be needed if any larger. also running semi slicks wouldn't be a problem. sounds like you guys in America and the uk are a little bit scared of hp. I would haply sell the turbo if needed I didn't say it had to be that turbo. heres a video to educate you on the Australian way of life
