Hey guys I have an nb 2 with the 1.8 vvt and was wondering if anyone was running the m45 with e85 on a similar car, Im just looking for psi and horsepower figures but any advice is cool, I'll most likely be running an intercooler, also any advice on inexpensive injectors would be great I was thinking the rx8 yellow tops but I don't know yet, any advice is welcome thanks guys,
Noah

 

https://fuelinjectorclinic.com/flow-calculator Plugging some numbers in here, using 50.8psi (58.8-8psi for an NB) for 200hp at the wheels as a ballpark target you will need 340cc for gasoline, or 443cc for E85. If you wrer not looking at ethanol I'd say buy a set of flowforce 380s. Don;t know if RX8 injectors are compatible with E85 and even then most of the ones you will find are fake, or if they are legit they will need a rebuild which adds to the cost - that and they are old school - have shitty atomization and aren;t linear at lower pulsewidths - shitty idle

the Flowforcesa are bosch EV14s so are a modern injector. If you plan to run E85 I'd say go with the 640s, if you are gonna stick with gasoline, a set of 380s will cover you.

 

​​​​​​Thanks for the advice man what I might do is start with gas and if I don't hit the numbers I want than move to e85, I'm not really worried about a rough idle cus she's a drift car and just trying to make a bit more power up top as cheap as possible so I'll probably go with yellow tops anyway, and I'll go through a part out to make sure there real.

 

Skip the yellows unless you pull them yourself, too many fakes these days.
a water meth kit pre supercharger will do a lot to help the top end and heat soak also is pretty cheap

 

I'll definitely pull the yellows myself if I decide to go with those I keep hearing about the fakes, and I'll definitely consider meth injection but it kinda seems like a Hassel hot getting me up and running, I will definitely keep it in mind tho when I'm looking to put more power down down the line, do u have any suggestions for a specific kit, I don't know mutch about meth injectionThanks for the advice tho

 

put one together yourself imo. superchargers and water injection go together quite well.
get nozzles from your brand of choice.
you can get threaded holders from the hardware store, same with nylon tube.
used pumps can be had for cheap, or get a really high pressure one new.
and then you need a solenoid valve, and relay, again get those from a normal brand
oh and make or buy a tank that will fit into your preferred location

 

I am selling some 350 cc injectors that I only used for a few hours before switching to something even bigger. Make me an offer - https://www.facebook.com/marketplace...0796850326093/
