I'm thinking about saving up money for a 1.8l, I was wondering if I got a 01+ 1.8l VVT would it work? Would you have to swap it to the Protégé Dizzy, or could you leave it as a C.O.P(coil on plug) setup, if I used a megasquirt? What all do you need other then intake manifold, and water pump would be needed to swap it to FWD? I'm just asking engine wise, I know you need to modify the engine bay, and mounts.

Better to start with a VVT from a front drive, much less fab work.

There are no FWD VVT equipped 1.8L

You can’t just mount a FWD intake manifold to the 99+ Miata engines(including the 01+ VVT equipped ones).  The intake ports on the 99+ Miata cylinder heads were raised and are located at the top of the manifolds mounting surface to improve airflow, while the FWD protege/escort manifolds have the runners still located at the bottom.

I think I read that the BP or BPT/GTR intakes can be modified to work on the BP4W head.

I do recall somebody using a modified GTR manifold.
IIRC..He had to weld up the top mounting holes on the manifold.  Then drill new top holes and cut the lower section of the manifold flange off and welded a  piece of aluminum to extend it lower to match 99+ head bolt spacing.

I also remember something about having to customize the Miata fuel rail so it would mount to the GTR manifold due to the way the 99+ heads have the injectors going into the head.

Oh that sucks, would it just be better to make a hybrid out of the VVT, and FWD intake then?

 In your opinion is the VVT worth it considering its only a extra 10hp up top?
 
What variants of the BP where offered as FWD?

Do you think swapping to the coil pack set up would be worth it, considering that the 1.8l Dizzys are such a pain in the ass to find?

According to Wikipedia:

BP[edit]
The 1,839 cc or 1.8 BP is a DOHC (double-overhead camshaft) variant of the B8, featuring an 83 mm bore and 85 mm stroke and four valves per cylinder. This engine was called 'BP-ZE by Mazda engineers' and featured a forged crankshaft, piston oil squirters, a structural aluminum oil pan with cooling fins, a 7,000 rpm redline, and Variable Intertia Charging System VICS which is activated by a control solenoid at high rpm to increase horsepower in the upper rev range. The engine in base form on 91RON fuel produces 96 kW (129 hp) at 6,000 rpm and 165 N·m (122 lb·ft) at 4,000 rpm. The engine is a favourite for both N/A and turbo motoring enthusiasts for its robust design, materials and construction. This particular variant can be found in the following vehicles:
1989-1994 Mazda Familia GT (European & Australian Market)
1989-1994 Ford Laser TX3 (Australian Market)
1994-1998 Ford Laser KJ GLXi (Australian Market)
1994-1998 Mazda Artis "LX" VICS jm1 (North America Market)
1990-1994 Mazda Protege LX (with VICS)
1995-1998 Mazda Protege ES (Australian Market: 1994-1998 323 Protege SE)
1990 Mazda Infini
1990-1991 and 1993 Mazda Protege GT (Canadian Market)
1990-1993 Mazda 323 (European Market)
1991-1996 Ford Escort GT and LX-E
1991-1996 Mercury Tracer LTS
1995-1997 Kia Sephia RS, LS, GS
1994-1998 Mazda Familia (Japanese Market)
1994-1998 Mazda Lantis
1994-1997 Mazda MX-5/Miata (did not have VICS until 1999)
1996-1998 Suzuki Cultus Crescent/Baleno/Esteem
There is also a non-performance SOHC version that is most easily recognized by its black stamped-steel oil pan. It also features a cast crankshaft, no oil squirters, a plastic oil pickup tube and less aggressive camshafts. It is found in the 1995-1998 Mazda Protege ES.

This one looks like it has a lot of promise to me:

The bp is predominantly seen in fwd cars as well as the bg Gtx and Gtr. You can run it on an EVO ecu with cop's right now for 400.00 from a guy in Florida. They are making over 400hp on those motors with stock n/a internals. Knowing that why would you want to deal with the much more difficult swap of the bp4w or the mzr.

[WashiestSnake]

I honestly dont have to have the BP4W, i was just trying to see what variants might work, because id like to get the newer engine technology in my car, so that i could possibly make higher horsepower much easier. I know the VVT is usualy what most Miata people want for when their turbocharging because it gives you more top end torque, and horsepower.  Knowing now that you can make that much horsepower on stock internals, really is making me change my mind.
