3rd gear boost cut? it flats out at some point but doesnt cut
I am the second person to have this issue that I know of. When you redline 3rd gear the ECU will shut the fuel?/spark? off for 1-5 sec. After that period the ECU turns everything back on, and you can go about your business accelerating through 4th. If you don't redline 3rd, and shift into 4th before redline the ECU won't cut fuel?/spark? I have no speed sensor attached to the ECU
You can also use the measuring shims to do this as well. Alot of the UK guys cut or punch the shims and place them under the OEM ones to get them within spec. Its alot cheaper and works just as well and is safe. Im gonna do it!

I'm probably gonna do this as well because my lifters on the cylinder near the cam sprokets are annoying!! just waiting until i get my front mount and new valve cover which will make everything so easier ... did anyone take off the cover on a gti-r sr20? damn, all those hoses are in the way and you have to painfully undo them all ... takes a while
Man - this is great. I joined SR20forum a while ago just poking around cause I had it in mind to buy me a P11 Primera (USDM G20) and swap an SR20DET in it. I ended up getting a deal on one that had a swap in it already! Only after I bought the car then I figured out that the GTi-R engine was yet another type of DET out there!
Hadn't been on this forum for a lonng time - but this is a most welcomed section.
wow this is a great idea i have a 1998 200sx se-r with a 1994 rnn14 gti-r motor swap and io need help i need a throttel postion sensor do you have one or can you get one i will pay what ever it takes my car is totaly done but has a bad tps can you help
gary, aka, gti-r 200sx
ok so.. i got a stock gtir set up, complete engine, harness, ecu, and maf - in my 93 NX2000.
daily driver, drove nice, realllly nice. for a long time..
all of a sudden my fuel would always cut out when i was acc., i just drove it slow for a while till it drove me nuts.. ( Still does )
i finally got time and took it back to the shop where i installed it and said this..
when i pin my gas.. any gear.. it will cut out...
so in N we reved it out. -pedal to floor- cuts and revs 1g to 1.5g bogging.. right on those rpms.
so with the hood open the man was looking around.. tighening the maf and holding it in place the car revved out fine.. let go and it was still reving.. so with hopes so high..a test drive had to happen.
it seemed to cure the problem, for the most part..
know it would let me jam first gear, get to second and then cut out.. or going slow to 3rd or 4th, i could drive and pick up as hard as i could but if my pedal hit the floor again. it would bogg out again.
i have no idea wats going on, they seem to think its the maf sensor failing- and im having a HARD time finding one to replace it .
any other set ups possible
sorry for a ramble.
To use a Z32 MAF you have to send out your ECU to JWT so that they can tune it to use that MAF. It's $600 to have JWT tune your ECU and prolly another $150-$200 for the Z32 MAF. So you're talking about $800 after you add up shipping costs. That's a little expensive if u ask me. Besides the GTiR MAF that you have is goot for 290 HP, you don't need more than that for the setup that you have. You probably have a problem somewhere else. Check out you're TPS first. Use your DMM and put it inline with the signal wire the voltage should read .5 or so, and then slowly open the throttle, you should see it steadily increase to no more than 5V (like 4.5). If your TPS is good, check your MAF.
i just got this as advise.. what do you think of this as well.
First, you'll need a digital voltmeter and a small flat blade screwdriver.
The MAF sensor is located just past the air intake. You'll need to pull back the rubber cover to expose three wires. On mine, the outer two were orange, the middle one is white. The middle pin is where we need to get a voltage reading from (with the engine idling). Take the positive lead of the voltmeter and make contact with the middle wire. The negative lead should be pressed to one of the ground connectors on the engine block, near the firewall, right behind the fuel injectors. You might have to look hard to see them, just look for a bolt with several black wires running to it. Took me a while to spot it myself, several vacuum hoses in the way...
The voltage read should be less than 9mv (.009v), if it is above this value, the sensor needs to be reground. To do this, a wire needs to be run from the middle pin to the ground lug. You'll need to remove the connector from the MAF to get a good angle on it. On either side of the connector is a small opening for a small flat blade screwdriver. There is a wire that runs around the connector to hold it in place, you need to pry this wire outwards, and then move the connector back a bit. Do one side, then the other, and it should pop right off. I'd never seen this type of fastener before, once you have it off you'll see what I mean.
You'll want to solder a new wire to the middle pin, make sure you get a good connection. Then, run the other end to the ground lug. If you want to do the job right, you'll want to get a connector from Radio Shack or other electronics store that has a ring that you can crimp the wire to. I don't remember the size of the bolt, so I'm no help there. I just looped my wire around the bolt twice and put it back on. I may go back and fix it up nice some other time.
Once the sensor is reground, the voltage should drop significantly. Mine was at around 11mv, after the fix it went down to less than 2mv.
Looking for a FSM to sort out what needs to be in and what can go as down here in Georgia, their are know emissions as of yet, so I am getting rid of the farm as per say.
Next item is building for extreme Hp on a GTiR motor, where to start and who to deal with stateside for the best work? I was veiwing the Tomei site and I want Tomei performance without the stroker kit and without Tomei pricing.......he he.......suggestions are welcome.

Well this is nice i own a 1992 nissan GTS 4wd with the GTIR engine i have some cams 270 schinder i was wondering if the could be haded to the set up or i would have to re shim the cylinder head i would love all info like hp cam sec piston spec
