NB engine in NA

green_comet · Postby **green_comet** » Fri Apr 06, 2007 2:14 pm

Hi everyone,

I just wanted to know if it is possible to use a 2000 NB engine in my NA8. A friend of mine is selling his engine, and im very interested in using it in my car. Is it possible to use the standard NA8 ECU, and loom?

Im looking at modifying it over time, then installing it.

Cheers
Ryan

Is VICS the same as toyota TVIS? Basically just butterflies in the intake manifold that open at a certain amount of vacum, or rpm?

If i can get a kit from Jaycar, then i think ill go for it..

Is there much involved in keeping the Crank Angle Sensor?

The engine needs to have its big end bearings changed, is that a tough job. I mean i was going to rebuild the engine anyway.

Thanks Steve

I also ordered a copy of Mazda Miata MX-5 Performance Projects by Keith Tanner, it has a full guide on the head swap..

Quick newbie questions...

I'm contemplating a 1.8 upgrade into my NA6. Will I need to change anything else such as gearbox, clutch, etc?

What year make of a 1.8 will fit into the NA6? (up to and including)

I got a quote today for a 1.8 transplant (incl labour) for $2200. It would be a motor that's had 30-40 thou k's on it. What do you guys think?

personally I wouldn't bother with the 1.8 conversion Deez, all you have to gain is about 11kW and alot of money to lose. Plus if you are into and CAMS events at all such as sprints it would be putting you up in the up to 2.0L category for very little cain. If you reallu wanted the 1.8 you could probably sell your car and buy a 94- which already has bigger diff and brakes and more bracing, or as an alternative put the $2200ish you are looking at paying a mechanic into setting yourself up with some snail power.

put he $2200 into a turbo build and gain minimum 30% more hp
or for 1k more get a supercharger and gain a guarenteed 40% more hp
much better then the nb swap IMO

where are these 2200 turbo builds?
Even a basic greddy kit is more thanb that, add in the cost of fitment (cause you are including that with the new engine) and it quickly adds up...

The NB 1.8 has controls the alternator differently AFAIK but you could swap them over.

You can adapt a shift light to control the intake.

DIY ofcourse

The $2200 may not get you all the way there depending on how much you do yourself, but it will sure get you close.

Doing the head swap is the way to go. That way you keep the original engine number in the car, no problems with needing engineering approval. (Though yes, technically it's an emissions-compliance-failing modification)

The Tanner book and miataforum support should get you through it.

Less than $2200 *CAN* get you a turbo set-up.

It'll work really well too, that is, until your clutch starts slipping, your diff explodes, your brakes start melting and you have to put decent tyres on so that you can ACTUALLY remain attached to the road... :roll:

After spending so little on the snail, I'm not looking forward to spending almost the same amount on a diff upgrade.

She's on her way out though. :lol:
