howdy, a B6T MX-5 might be coming to Adelaide? cool

Like you said, there's a reason you haven't heard of it commonly done...

In a nutshell, the turbo manifold layout doesn't suit the engine bay.

That has 3/10ths of stuff all to do with it. Whether you use a B6 or a B6T you still need an exhaust manifold to suit, which is going to set you back between $300 and $750 on average.

tick4d the reason I'd suggest it's not commonly done is because there is many cheap bolt on kits available which depending on how much power you're chasing, a kit will save you time and money. On the other hand I'm chasing big power so the stock B6 wouldn't be strong enough hence the reason I have a rebuilt/worked B6T from a TX3/323/Capri going into my NA MX5.

????????

the original question was "can you take a turbo motor complete out of a Ford Laser or Capri and install it into an NA MX 5?" the answer is no, because the complete motor will not fit. when asking about "complete" he would be including all the ancillary items that hang off the motor, such as the inlet and exhaust mainfolds, distributor etc etc.

The Turbo 323 / TX3 bottom end is stronger than the MX-5's, a lot of people have swapped this part into their MX-5 turbo setup.

If you only want to run 8 psi than an AVO kit is probably an easy way to go.

You can upgrade the engine/setup later when you desire more boost.

Yes, there are some technical differences in the bottom end (bigger rods, lower comp pistons off the top of my head), but not enough to warrant swapping to if you're only running 8 psi. A standard MX-5 B6 can take about 12 psi pretty easily (with good fuel and ignition management, but then that applies at any boost level)

Huh?

Matty was spot on.
The exhaust goesn't go back, it goes around/under. The intake manifold faces completely the wrong way. If for some reason you do decide to use that manifold, then the turbo points the wrong way too! Plus the turbo is extremely small...

So basically, no no no, don't waste your time and money.

Why specifically buy a B6T/BPT block if you're just going to strip it down? I did it just for costs savings as my engine was on its way out. At the time, everyone was trying to gouge me for the price of a MX-5 BP engine, so I bought a Familia BPT engine, and sold off the extras, such as the turbo. All I essentially ended up with in the end was an engine with a slightly lower CR.

If you're buying just the long block, then well, just buy the long block if you can, or buy an MX-5 block and work it yourself.

B6T bottom end is no better.

YES it has some bigger rods etc, but remember these engines are VERY used when you do find them.

If you want a monster, you'd be buying new rods and pistons anyhow.

or just put the turbo on it without rebuilding it. honestly, the standard motor is fine for boost up to about 10 or 12psi. i've gt 7psi on a bog stock standard motor, no problems at all.

i am running all the hardware (manifold, intercooler, piping, oil/water lines) from the avo bolt on kit, which includes a garrett t25 turbo. i did not use their electrics, instead i used a jaycar dfa to control my upgraded fuel injectors, which are from an rx7 (460cc injectors).

i assume your NA is a 1.6 ? this is what i have also. the general consensus is that the NA 1.8 is a better base car to use for a turbo upgrade. this is because it already has a stronger diff, brakes, and clutch. many people who put a turbo on a 1.6 eventually end up upgrading all these parts. so it could cost you a bit more in the long run than you initially thought. i haven't had to do this yet, but i have bought all the parts in preparation for when i need to (as i plan to upgrade my exhuast and turn up the boost to get more power). the other thing you need to consider is the legality of the mods, which varies from state to state. and from what i understand, south australia has very strict rules. so you might want to check all that out first.

I have a turbo laser engine in one of my cars at the moment...

Oh hold on, it's a laser

Brilliant! wuz that just to keep you posts up ?

Yeah it was... Have a look at my post count, over 2000, guess they are all crap like you're implying?

Actually if you bothered to run a search you'd have seen many posts about my turbo MX5 (now owned by miata bart) and more than a couple of topics discussing the laser engines...
