BRP MP62 Coldside Supercharger Kit

[1/9/2006] Reviewed by: Ari Mirles

Applicable to: '99 + 1.8 liter

BRP MP62 Coldside Supercharger kit. Supercharger mounted on custom intake manifold mounted on intake side of engine. This kit is a non-intercooled system with low throttled volume and includes a 75mm throttle body. Emissions legal with CARB certification pending. Once installed, only 18 lb. of added weight to the car.

This kit requires you to remove the intake manifold and install their custom manifold. Install was straightforward and didnt pose any issues oter than two of the lower intake manifold bolts being hard to reach. I had the first home install. Now BRP insludes a crowfoot instead of a wobble socket to make those bolts easier to fasten. I removed the old parts in 2.5 hours and installed the kit in 3.5 hours (I did many extras, such as rerouting wiring and cleanup). Once all was installed, the car fired right up. The kit has great throttle response. I later added a boost gauge and the needle instantly jumps to over 5 PSI of boost when I press the throttle and has a max at around 8 PSI. The car idles perfectly and has no cold startup issues. When driving around town and cruising, the car drives and sounds like stock, but when you step on the throttle the blower whine will make its presence known. :)

Quality product, smooth power with instant throttle response, hassle-free OEM-like drivability, excellent customer service.

The new BR Performance Coldside MP62 supercharger for the 94-97 1.8 Miata

What can I say. I was the first install of the new Coldside Supercharger for the NA 94-97 Miata. What a blast. BRP did the install and as always, it was first class. The car is now a freakin rocket. Idles smooth as stock. Sounds completly stock below 5000 RPM. I have put about 4000 miles on it so far with no real issues to speak of. This is the way the car should have come from the factory. Throttle response is as good as stock if not better.

Anyone looking to go FI should give them a call and go drive a car equiped with a Coldside or their hotside. Without a doubt, the best on the market.

BR Performance Base Hotside Supercharger with ELF

BRP Hotside supercharger with Plug and Play Adapter, Cold Air Box, and ELF.

Over all the kit is very well engineered and built. Installation is not difficult. I took me about a day and a half but that was because I cleaned polished and nit picked over the entire install. The PNP adapter made installing the power card (later upgraded to ELF) a snap. Instructions were a bit vague in places but Tech support is just a phone call away and the guys at BRP are VERY helpful. I only had two problems one was mine, the other was a jumper left off the PNP. But as I said the fix was just a phone call away.

I have had the SC on since OCT. When it was first install the power was a real hoot, it still is, but you get used to it and then you start planning the next upgrade. My wife is very happy with the SC and wonders why Mazda didn't build it this way to start. I have had no problems with the SC and have made several decent road trips. I did have an idler pulley go bad but it was my fault(over tightened) and BRP replaced it under warranty. I have a lot of confidence in the reliabilty of this kit. They also have a great website. I look forward to working with BRP for a long time. Bravo Zulu

BRP MP62 S2 for 95

This is the MP62 Supercharger kit from BR Performance. It includes the JR Powercard and a big throttle body.

After a few weeks of waiting, I finally got the kit I have been drooling over. I tore into it as soon as it hit the door. First impression was WOW! Slick kit. Everything was bundled up nicely and packed extremely well. After grabbing the instructions (that were a bit lacking, but that's just because my car was the first NA S2 kit)I started the install. It was a breeze up until trying to get the throttle cable adjusted and getting the supercharger aligned. After MANY calls to BR Performance, I finally took it to Clint Host to work out the bugs. Turns out I had a bracket by my header that was hitting the frame of the SC mount and it was throwing off the belt alignment. After he fixed this problem, it was time to take it out for a spin. WOW. Power is there when you want it. The whine is intoxicating and definitly needs to be experienced to truly appreciate. Overall, I give this kit a 9 out of 10 possible points. I had a few missing parts that delayed the install, but it was taken care of by Brant and the crew. I still have a little ping up top, but that is due in part to the hot weather here in Houston. Next on the list is a Bipes and a IC. I highly recommend getting the Bipes when you purchase the non-IC version of the kit. My timing had to be dropped down to 8, not too good for low end.

Good kit for the price. Customer service is great and upgrade path is wide open.

BRP MP62/S4 Supercharger System

[6/4/2005] Reviewed by: Bernie Johnson -

Applicable to: '99 +

The is a complete supercharger system for 99 miata that is designed to result in approximately 200 rwhp & 165 rwtq. First of all, I should point out that I am using the FM Link piggy back for fuel & ignition control. I already had this hardware and BRP offered to remove their fuel/ignition related hardware from their kit and drop the price.

My car is a 10AE with 52K miles, stock internals, Roadster exhaust, JR header and stock midpipe. The supercharger has performed well. I had problems with the overlay crank pulley spacer during the initial install. This was dicovered during inital release of the first few kits. Mazda produced more than one style of crank pulley and depending on which one is on your car, their are at least 2 different spacers. BRP warned me prior to my purchase that since I was getting one of the first production kits that there may or may not be some "teething issues." They were very responsive to the issue and addressed it quickly. It is my understanding that the crank pulley spacer issue has since been addressed. Throttle response is great and the power increase is substantial. I haven't autocrossed the car yet, but I expect it will be a great setup for autocross. The quality, fit & finish of the components are first rate. My car has dynoed at 200 rwhp & 170 ft lbs of! torque.

The BRP staff are wonderful people to work with. Although they sell "kits," they are small enough to be flexible to the customer's needs. If you don't want the entire kit or you are interested in some type of custom setup, give them a call. Overall, I would rate both the product and the customer service as excellent.

BR Performance GT25R Turbo Stage 2

BR Performance Turbo Kit - the GT25R/S2

Drove up from S. Florida Memorial weekend and had the guys at BRP install their new "GT25R/S2" kit (even the name sounds fast). I think mine may have been the first ready for production kits. The install was a breeze, beacuse I didn't do it :-) so I can't provide any feedback there- but what I can tell you is everything else. Here's what else I had added- the new goodwin high-flow cat (really nice looking piece) and the J&S knock sensor. I have an enthuza exhaust (not a "turbo" muffler) already and my car is a '01SE. I got 30mpg on the way up n/a, and got 28.5 on the way back, turbo'd. The sound is really really cool. Have been around very little turbo cars, but I just love this sound. Wicked is how I'd sum up the sound. It's certainly not a sleeper sound- when the throttle is down, my little '01 is transformed- and others know it. Ever since I put on Azenis, my car has felt a little sluggish (weight does make a big difference n/a), but not anymore. It's just what the car needed. The high flow cat together with the borla and more flow coming from the engine, really make a great sound. BRP said I could pick up even more HP with a turbo-specific exhaust, but would be louder- We did not have time to dyno the car, so I don't know what it's putting down. BRP was doing another kit identical to mine, so hopefully they have a dyno of that one up soon. But it's fast and smooth. I really don't feel any lag, just seamless power whenever I need it. During my first test drive with Brant, I even commented how it seamed easier to shift. Not sure why that is, but when really gassing it, quick shifts are like butter. The intercooler and associated piping is ceramic coated (I think?). It keeps the intercooler and the pipes near the turbo so cool. You can touch them after driving a while, and they are cool to the touch shortly thereafter. I've showed some buddies and they just shake their heads and say "man, that's a nice clean set-up" Last but not least, the guys at BRP are terrific to deal with. They stayed late to finish my install and then invited me out afterwards for a bite to eat. 800 miles or so back down to Florida with a high performance turbo and not even a hick-up. What else can I say except - wooooooossshhhhhhh psssst

BR Performance MP62 Supercharger

BR Performance R3 Supercharger kit.

My experience has been beyond my highest expectations. 248RWHP without replacing my stock ECU! I bought almost everything they make and had it all installed at once. Everything was installed perfectly over a period of 3 1/2 days, and nothing needed to be fixed or re-adjusted later. If you've ever worked on a car, or programmed a computer, you know how rare it is to get a complex installation and configuration right the very first time - no matter how many times you've done it before.

I brought the car to BR Performance for installation and tuning of their new R3 kit (mine was the first one). They installed a BRP custom-configured MP62 supercharger with an air-to-air intercooler, big throttle body, extra injector and injector controller, J&S knock sensor and timing controller, JR Powercard piggyback computer, Walbro fuel pump, PWR radiator, and gauges. The owner of BRP dyno-tuned the car himself. By the time he was done, my meek girlie Miata turned into a 248 RWHP Incredible Hulk. I was at the Dynojet, so I know it really did it! I say "Incredible Hulk" instead of monster because the car behaves completely as usual until you toe the gas pedal. Give it some gas, and it sounds (and feels) as if I have a Lear Jet taking off. It's a complete sleeper now, and is incredibly livable for daily driving. The amazing thing is, the special configuration and tuning not only gave me a ton of power, but it gave me a ton of reliable and safe ! power. If you want something fast and cheap, it won't be this good. If you want something this fast and good, don't expect it to be cheap. Well worth my money. Would do it again the same way if I ever get another Miata (only if this one gets stolen).

BR Performance Supercharger Kit

This is an update to my previous review. I upgraded the horsepower on the kit to the "System 45" specifications with a pigggyback fuel controller (SDS) and 2 extra injectors. This combined with a 60mm supercharger pulley gave the car a 20hp increase.

Driveability is improved with the piggyback controller and initial throttle response is much crisper. The power is seamless and immediate. Rear tire life has suffered and the clutch is now a bit fragile. This specification is now the standard kit offered by BR Performance.

This is a fun kit with good power and great customer support.

This is the Jackson Racing Supercharger kit that everyone knows and loves fitted to a 2001 Miata. The fitment required some mechanical fabrication and fiddling with the fueling. The 01+ Miatas cannot use a rising rate fuel pump mechanism like earlier models because they have no fuel pump return line. The BR kit includes different injectors, fuel pump, and a small fuel computer.

My car was the "Guinea Pig" so I wasn't involved in any way in the installation. My understanding is that it is similar to the earlier kits with the added steps of changing injectors and a fuel pump. The installation is very clean and looks factory. I'm very picky about the drivability of the car. When I spoke to Brant at BR Performance I told him that I was basically not willing to sacrifice any drivability to get the extra horsepower. After 500 miles with the supercharged car, I'm impressed and very pleased with the finished product. The power is much better all gears at all speeds and the last 1500rpm near redline are now fun to wind out rather than being flat and pointless. The car isn't going to slay a corvette but I would guess that 0-60 times are in the high 6sec range. The car idles, starts, cruises, and in all other respects behaves as nicely as the stocker. The new fuel pump can be heard if you're stopped with the radio off but otherw! ise the kit is really refined.

The character of the motor is slightly coarse just off idle but then revs urgently with a very cool supercharger whine that sounds like someone is mixing frozen daqueris under the hood. Brant had suggested to me that a slightly throatier exhaust would "balance" the intake and exhaust noise and I'm inclined to agree. I hate loud pipes but the stock exhaust note is so subdued that the blower whine drowns it out completely. A muffler is on order. So the car is a hoot to drive and I would highly recommend this mod to the person who would love a fast Miata but is afraid of screwing with the car's basic goodness. Those in search of viper-slayers should probably look elsewhere. The car dynoed at 151hp at the rear wheel and the charts are available in the forum section of Note: I'm not affiliated with BR at all but Brant did a great job. He definitely delivered more than he promised and consistently chose the safer path rather than t! he cheap one.
