WILL I BLOW MY ENGINE UP ???

Blue sky dreaming.....

Plonk all the easily obtained and cheap SE gear onto a NB8B VVT engine. All I would need is...

Turbo
Manifold
Exhaust
Intercooler
Engine Management (probably have to be non SE)

Costs....
$1000 parts, second hand
S1000 install
S1500 engine management and dyno.

Achievable?
The VVT is the same high comp motor as a SP - would it be way more awesome than a standard SE :?:

Just a small point, would also need the SE injectors and some water oil lines as well.

Yeah but it would suck.

T25 setup will cost not a lot more used and be FAR better.

Maybe true but I am looking for a strictly minimalist approach to start off with. KISS.
Say my NB8B has 95rwkw now, I would be happy with 125-130 rwkw and not compromising the engine.

All these parts are cheap cast offs from SE owners who really want something special, but we know they fit and being Mazda OEM are safe and reliable.

A cheap T25 setup would only come from the MiataTurbo guys would it not?

SE intercooler available for free from me. Not quite worth the money.

All SE donations happily accepted.
Your unwanted crap is my performance upgrade!

Get yourself a cheap bigger intercooler!

good deals for t25 kits come up on here occasionally.

I really recommend going a t25 or t28 kit. just think there has to be a reason the se guys upgrade to it. the only other thing you may have to upgrade is the clutch.

our engines are pretty forgiving for turbos and even poor tuning (to a limit).
they are not a ticking timebomb as soon as you turbo.

one thing is forsure though... youll love the turbo

I suppose the fact that the Mazda dropped the VVT and plumped for low compression pistons has got me a bit nervous about turbo power on a NB8B engine. Still the SP appears to be durable enough.

You will also need an SE water pump inlet, SE radiator support brackets, SE intercooler brace bar, SE sump, SE or early NA8 block (or yours drilled and tapped for hard lines).

Thanks Sab, that is exactly the detail I am looking for.

HKS thanks as well, that is a hell of a good article on SP.

This is my big question.....Maybe I should start another thread with the title.

Is a NB8B VVT with SE gear ( I dub it - SP Lite

) going to be significantly faster than a stock SE :?:

No. Plus you will have the additional problem of setting up an aftermarket ECU to run the VVT - the std NB8B ECU won't work with your turbo install, and the SE ECU won't run the VVT.

Already figured a ECU and tune would have to be budgeted for, $1500, see above list.
Surely the aftermarket ECU and dyno tuning alone would make it significantly faster to a stock SE

Plus you have the high comp NB8B to start with.

The only ecu and tune you'll get for that is a mega squirrel and some fine tuning on a dyno. Vvt adds extra complexity (time). A ground up tune from a shop is likely to be min 1500 alone assuming they are familiar with the ecu.

Edit: I noticed auto correct like squirrel more than squirt... But I left it.

You can make nice power and torque with Vvt but not really the way to go on a se cast offs / shoe string budget. I think you'll find it Cheaper in the long run to just buy a car done or do it properly the first time.
