Hi everyone, i have already make my presentation on the previous post, i really need some ideias and i hope i get some help here...

i have the chance to by a supercharger full kit for a mk1, i have a nb 2002, it's include all the things needed like injectors,ecu,intercooler, supercharger... if i buy it it's compatible with the nb? does it need some minor changes?


thanks
Gil

Some more info would help us helping you. What are your overall plans for the car? Is it a 1.6 or 1.8? What kind of kit/supercharger? I can tell for sure that a NA ECU is not going to work on a NB2.

thanks for the help, the information that i have is this one:

Up for sale complete mk1 1.6 supercharger kit.
Pnp ECU.ev14 injectors .dual throttle bodies.
Low mileage m45 mini charger with t r lane inlet outlet and mount kit.
Custom.made radiator and intercooler all.pipework air temp sensor.adjustable tps for mapping.

mine is also a 1.6, i know the ecu is different but about the rest? thanks gil

Edited because now I see you have a 1.6 NB..

HarryB

The charger, mounts and injectors (provided they come with pigtails) will work as-is. IC and piping can be made to work, NB throttle body is positioned slightly different. You do not need the vtps, NBs already have one. Obviously you will need an ECU.

I am unsure if the radiator will work as well. I know that OEM mounts are placed differently, but maybe it can be made to work. To be honest, unless pricing is really good, I would go with Salon kit, buy a used charger and piece it myself.

thanks for the feedback, my ideia is getting about 150hp, i think that until 6psi i don't need ecu, so my ideia is to put the supercharger put it at 6psi and put some kind of fuel management, is it enought to get 150hp? thanks

i left some pics of the system to check if someone can tell me if it fits....

about 500€ is a good price?

thanks

You will need some sort of engine management. I would go MS, but that's my preference. The IC/radiator setup looks to be a DIY thing, using a Civic (?) "half" rad. I guess it could be made to work but TBH, the only thing I would buy off of that setup would be the supercharger and mounting system, plus the injectors. That being said, the price is good.

List of what you will need:
Supercharger with proper inlet/outlet
Supercharger mounting system & belt
2nd TB (could be made to run with a dummy TB as well) and pulley system
IC and piping (plus diverter valve)
Injectors
Wideband sensor. I spot an innovate box on the photo, is the wideband O2 sensor part of the kit as well?
Some form of engine control (would go standalone)
Upgraded radiator
Upgraded clutch
Would also update ignition coils, 1.6 ones are a joke

Hope I am not forgetting something!

Now, if you know the SC is in good shape, the mount is of decent quality, and the injectors come with data and are not e-bay junk, I would buy it for these alone, as the price is low enough.

Gilberto Rocha

Thanks for the info i will try to get the kit... Do i need all that stuff to get 150hp? I thouth that only sc or turbo and some fuel mod was enought to run at 6psi thanks

HarryB

At minimum you will need the supercharger, mounts and piping. Given the usual climate at Portugal and the fact that M45s generate heat, I would also suggest an IC. You will need injectors, stock 1.8 ones should be adequate (but probably not the best idea). You will also need some sort of engine management, that can be a piggypack or standalone ECU. Price difference between those two (used) would be 2-300 euros, and IMO it is worth it. You will also need a wideband O2 sensor to tune it.

I see two options.

1. Cheap way: Buy the kit as-is. Sell ECU and injectors. Buy piggypack, NB2 1.8 injectors, wideband.
2. Less cheap: Buy only the SC, mounts and injectors (yet unsure on what they are). Get an eBay radiator & IC. Buy used wideband & standalone ECU.

Also, the 1.6 clutch is not going to last long with boost, so you WILL need a clutch in both scenarios.

Gilberto Rocha

thanks harry, normally cheap way=problems, so i will wait i get better hardware... a turbo setup is virtually the same regarding costs right? only changing SB with a turbo but the rest is the same?

slug_dub

If by SB you meant SC (supercharger)... don't forget you will also need a dump pipe form the turbo to the rest of your exhaust system. A supercharger setup doesn't change your exhaust piping but a turbo does.

HarryB

Turbo, you will need a manifold and downpipe, water and oil feed and return to/from the turbo. The rest would be virtually the same. I expect a modern, properly sized turbo to be better in every single aspect than an M45 (and be able to make more power too).

Since you are in Europe, I would suggest checking out Kraken for a turbo manifold & downpipe; great products, at extremely good prices.

M45 is a good choice if all you’re looking for is 150hp, but trust me you will want more. M45 will wake up the miata for sure and is a decent choice for ease of install and reliability, I had plenty of fun with it for the 9 months i had it before i itched for more.

I wouldn’t worry about intercooler at 6psi as all the extra volume added to the intake (post TB) is going to make the low rpm drivability and idle rough to dial in. Dual TB will help here, but will require careful adjustments.

If you go M45 route find another kit that’s more or less original.

Bandaids such as fuel card or rising rate fuel pressure regulators will just annoy you and will never get you to a safe AFR level across the rpm band. ( i know all this first hand ).

At the very least get MS2 or DIYPNP. Injectors 515cc ebay stuff plug n play worked for me (~$100). Stock Clutch will start to wear after 140wtq.

I think at end of the day you will be happier with a basic turbo kit that will be infinitely more upgradable. In my case i switched from M45 160whp/140wtq to a GT2560R kit with 250whp+ potential for $800 more.

M45 will be maxed out at 175whp at the cost of a turbo setup that will do 100whp more to start.

That setup in the pics seems to have halved the size of the radiator to fit in an IC, which seems like a terrible idea.

Thanks for the information I lost the bidding on the sc, ended at 1000€ l think im going to Turbo 😁 i will try to find one at a good price
