Finally picked up my KA-T S13 from Tommy of Raymond Motor Works, everything is good except there's an issue with the fuel or tune that I need to sort out myself and hopefully you guys can help me out.

The car runs really lean under boost with the maf setup blow thru and the fuel pressure turned way up. It also ran really rich at idle with it setup draw thru (didn't try driving it this way), it idles very smoothly with the maf unplugged. He believes the issues is one of three things my maf (n60) is fried, the sr injectors I got from someone off the forums aren't good, or my enthalpy ecu tune isn't correct for my setup. Generally the A/F is all over the place.

So I'm looking for anyone in or around NYC or within about 2 hours driving distance that is selling an N60 maf and/or a set of injectors. Or anyone who is willing to meet up just to let me borrow their maf or injectors to test to see if that is the issue so I can then know what I need to buy or any other help. Really want to get my car running properly asap.

Any and all advice other advice about the situation would be greatly appreciated.

I'm also looking to buy a few other misc. parts: brake reservoir cap, dohc throttle cable bracket, consult port, and a gas pedal (not the whole assembly just the rubber pad)

My setup includes:
unknown tubular top mount manifold
turbosmart ultra gate 35 w 7psi spring and no boost controller
t3/t4 turbo
enthalpy ecu (possibly setup for n62 and different injectors because I changed directions about a dozen times and kept emailing them different setups, waiting for a response from them also)
n60 maf (possibly fried before or during my last motor blowing up)
sr 370cc injectors (possibly no good and partial cause of previous blown motor)
obx fpr
FMIC
hks ssqv
mishimoto radiator
3 inch turbo back exhaust
underdrive crank pulley
arp head studs
cometic head gasket
stock plugs are in the car now but I also have a set of the one step colder ngk's
all emissions removed, butterflies removed etc.
circuit sports catch can
godspeed turbo blanket
aem wideband
autometer: oil, boost, & water
jgs oil line kit
jgs engine mounts
isis power steering line
welded diff
eibach springs & kyb's
energy suspension master bushing kit
tein tension rods
MOOG sway bar endlinks
staggered xxr 527's w federal 595 (fenders need rolling badly & need alignment)
300zx front calipers

All the things you're not sure about (tune, maf, injectors) are extremely extremely important.

Especially the tune.

Double check what your ecu is tuned for before driving the car.

this is the 1st issue that should be addressed

Yea I'm waiting for a response from enthalpy about the tune.

My buddy has a set of SR injectors that we're going to swap in tonight and see if that helps.

Hopefully I can also locate an n60 and/or n62 MAF locally and get this thing sorted out without having the wait time of sending the ecu back out to enthalpy.

I'll post some pics of the car this weekend and BTW it will be for sale in January since I'm moving to CA and getting an EVO X :biggrin:

Of course after I run across town to pickup an N60 MAF from a guy off craigslist I get home in time to get an email from enthalpy saying my tune is for a Z32 MAF. Luckily my buddy has one so we'll see what happens tomorrow.

No I haven't but I'm pretty sure Tommy checked them before I picked up the car and wasn't getting any. I'm trying to get my hands on a consult plug.

Today she sprung an oil leak at the T fitting on the oil line, then when trying to fix that the fitting broke off inside the oil block so she's at T&R racing in Queens and their getting to get that sorted out for me. I just got an N62 MAF from my friend so unless there's some other issue that I'm missing she'll be up and running tomorrow.
