Miata with a BPT?

inferno94 · Post by **inferno94** » March 6th, 2006, 4:37 pm

Does anyone know of a miata with a bpt or if it's possible (within a reasonable financial investment) I have the opportunity to buy a 95 rs mx3 or a 97 mx5 both mint (rust free) mx3 red, mx5 brittish racing green i have a bpt in a tired 323 (the engine is running great at 14.5psi). I want to either make a super powered ms mx5 or convert a mx3 into a t-top 2 seater (the one I'm looking at doesn't have a sun roof). Any help is appretiated.

http://en.wikipedia.org/wiki/Mazda_MX-5

Generation 1.5
The MX-5 Miata was freshened for 1994 with the introduction of a more powerful 1.8 L BP engine, dual airbags, a geared, torque-sensing limited slip differential, and other options. The new engine produced 98 kW (130 hp) and the standard model weighed 990 kilograms (2183 lb). In some markets such as the UK the 1.6 engine continued to be available as a lower-cost option, but was detuned to only 88 bhp to make it less competitive with the 1.8. Later 1.8 engines were up in power to 133 bhp due to the use of a more sophisticated engine management system (OBD-II).

Generation 2
The BP-4W engine remained at 1.8 L but received several minor updates. The engine compression ratio was raised from 9.0:1 to 9.5:1 by adding slightly domed pistons. The intake cam was changed to a solid lifter design with a stronger cam. The intake runners in the head were straightened and the intake manifold was mounted higher up. The new intake manifold received a set of flappers that could uncover a resonance chamber - this was needed to fix a dead spot in the torque curve that the new head created. Power output of the new engine is quoted at 105 kW (140 hp) with 119lbft of torque.

Generation 2.5
The 1.8 L BP-Z3 engine was slightly modified and now featured variable valve timing on the intake camshaft. The intake and exhaust system also received a minor upgrade. These modifications resulted in power output of 117 kW (155 bhp) for models delivered in Japan and Australia. The same engine produced 110 kW (146 hp) in vehicles sold in the United States and Europe (likely due to more restrictive emission standards). In the United States, Mazda erroneously quoted the power figure for the Japanese and Australian model in early catalogues. Car and Driver magazine and numerous owners confirmed the missing power, and Mazda was forced to buy back a number of 2001 cars due to these misleading power claims. Owners who did not take up the buy back offer were offered an apology and free servicing for the warranty period.

Mazdaspeed MX-5
2004 saw the introduction of the turbocharged Mazdaspeed MX-5. It featured a light-pressure turbo BPT engine for 178 hp rather than the S-VT BP-Z3. Other features included a special suspension, upgraded transmission and clutch assemblies, upgraded drivetrain components, Racing Hart 17 inch wheels, special interior trim, and special exterior paint.

Though not officially a "Limited Edition" production run, only a small number of Mazdaspeed Miatas were produced during model years 2004 and 2005. In 2004, 4000 cars where built and in 2005, 1428. Production numbers, VINs and build dates are here: http://mazda-speed.com/forum2/index.php?topic=933.0

There are also many turbo and supercharger kits for the Miata. The owner of the place i get all my new audio equipment from has a supercharged miata...but I've never though to ask if it was a 1.6 or 1.8.

Ya they are thinking about calling it the MX-3! But with the miata yes it is posable to get a bpt in a miata you jsut need to make some new mounts and the steering bar gets in the way you need to do something about that. I contact corksport and they gave me the info for it.

Wait i think they are going to call it RX-3! =)

the simple option is to buy the Mazdaspeed Miata with the turbo already in it..

Ya I am with him on that one. Mazdaspeed miata would be easyer. What we are going to do is just get a new 1.8L motor for are miata and just get a turbo for that. I found some nice turbo kits for a stock miata.

Legato626 · Post by **Legato626** » March 19th, 2006, 2:48 pm

there is 2 different vs. i beleave. one that does 190 (remember 4 banger

) but i beleave there is a 210 or 220 hp vs. I think. Look on corksport.com they have the info on there for them.

The GTX BPT is rated for 180 hp, and the GTR is rated at 210. Mind you, both engines can easily hit 220 WHP with a little bit of tuning.

Not in a stock (MazdaSpeed) Miata. Only in a stock GTR 323 (210hp).

Only if it came with a Rotary engine, which is highly unlikely at this point. They seems to be pretty set on the MZR 190hp i4

I would get the Miata and just bolt a Jackson Supercharger to it instead of going through a BPT swap. It's only a $2200 kit straight from Jackson, which is cheap compared to alot of turbo kits.
