GTiR NX2000 Swap - running extremely rich!

[VisionRx7]

I just completed a sr20det gtir swap into a nx2000. The car is running so rich that it fouled out the plugs in about 5 mins of idling/driving. I was told to use the stock mafs from the nx2000, but I am doubting that now. The mafs plugged into the gtir wiring harness. Can anyone confirm that the stock nx2000 mafs is the same as the gtir's?

BTW, the engine's electronics are stock, so there is no way for me to tune the fuel in. Also, it looks to have the stock top feed 444cc injectors (yellowish with the JECS A46 00 marking). I know they are low impediance injectors, so the stock resistor pack is wired in.

Thanks for your help,
Jesse

Im not positive, but I highly doubt the MAF is the same on the NX and the gtir. Im not too familiar with the NX, but i helped a buddy do a bluebird into his b13 sentra. Im almost positive he had to use the MAF that came with the motor.

I would think the MAF is completely overwhelmed by the GTiR motor as its larger, FI, and puts out probably close to twice the power of the stock NX motor

You need the GTI-R pulsar MAF. It is one of a kind.

Awesome, thanks for the replies!

Go over to www.sr20forum.com - that forum was pretty much founded on FWD SR engines, and there's more info than you could ever need. Just make sure you do some searching before asking questions, otherwise you'll get told to search anyway.

Good, its been a few months so Idk the part number, but it has to be the exact one, no exceptions.
