Default what next

If ive missed something or you need more info just let me know

Right had the car dyno'd yesterday and it made these figures.

168.8 ATW 139.something ATF and 138 ftlb at 4.2 psi not the 5 it should be running.

Bar the slight boost loss everything looked spot on.

The car is a JDM VS 1.8 6 speed with a non i/c HKS turbo kit (FCON Mini)

The plan is to fit the I/C and get all the centre section exhaust made up to 2.5".

Im stuck from there i know fuel pump, injectors and management but i dont have a clue where to start.

I'm a firm believer in you get what you pay for so dont mind coughing up the pennies.

So whats your opinions gents.

Seems like logical progression. Definitely check out the DIY FAQ if you haven't already.

Depending on your power goals, you could go with some supra 305cc's, an afpr, and a bipes (for timing), or go ahead and get some 450cc or greater injectors and a megasquirt and be done with it.It looks like that HKS F-CON isn't user programmable and is set up for only 5psi, so you'll end up ditching that. For the fuel pump, I'd recommend a Walbro 190lph HP.

You've defnitely come to the right place to learn turbo miatas. I'd have never got boosted if it weren't for this forum.

Apparently you're a non-English speaking Turk.

Forget the afpr and bipes if your getting a megasquirt. I your looking for big number invest in a oil cooler, get a lsd if you don't have one. Other than whats in the DIY thread build then engine and your done with it.

Get a megasquirt and some 550cc injectors

2 1/2" pipe will make it breathe better than stock. Although a 3" would give you less backpressure.

You can keep the stock fuel pump but upgrading to a walboro 190lph would give you some head room.

And like you said, an intercooler.

Should get you there.

He doesn't need an oil cooler unless he's putting the car on the track. You should keep to posting your horse-**** advice on clubroadster and only lurk here. This place is holy, you're a ------.

I saw your reported post. Go ahead and reply next time that you think hustler's advice to not run an oil cooler unless you're on the track is bad advice.

Because people will flame you just like you expected when you reported instead of responded.

There simply aren't any places on the street you can run through 4 gears flat out several times in 2 miles within 20 minutes to heat the oil that much. And if you are clever enough to find these places, you probably have an oil temp gauge already.

For a non-forged (sub 250 rwhp) motor driven on the street like 99% of us drive on the street, you dont need it. Run oil that wont break down under hihg heat and change it twice a year and you're not going to have problems an oil cooler would solve.
