If I where you I would go stand alone but if your going to be trying this for some reason before you get the haltech friday then you need these upgrades
720cc primaries
1000cc secondaries
SAFC
fcd or rtek 1.7 (rtek is nice because it retards timing as well as other stuff)
wideband o2 sensor and laptop to datalog with or bring your car to get tuned ASAP!!!!
larger fuel pump (search for walbro 255 or go to rx7.com and get their fuel pump)
if anyone can think of anything else chime in but this is the main bulk of what you will need to protect your engine against big big problems. Probably not having an fcd has saved your engine so far.

Ok Like I said, hatlec is comming... Im using a VERT ECU, VERT PRESSURE SENSOR, so I see no reason as to how it could be fuel cut... AND I have never experienced fuel cut in that way, usualy it just bogs or hesitates, but never sputtered like that. I have 720's with walboro and pump amp. TO better give an idea of wat its doing, If any of you have seen a two stepp or antilag in action, then thats exactly whats happening... why would I buy an safc if Im getting a haltec. I retarded timing, and ran 110 gas, the car runs rich as it is.

lol, don't run it then until you get the "hatlec"
I wouldn't try dicking around with this setup man, go standalone before you screw something up. Why do you have a vert ecu with a tII engine??? How the hell is that working? But your right man I don't think it would fuel cut if it's not a turbo ecu.....

Im pretty sure your hitting stock ecu fuel cut level. I dont see how you could possibly go much above stock boost without stand alone or the fcd like so many have said. The answer is in fuel delivery somewhere. But yeah definitly keep it shut off cause if its not the ecu and it is the injectors not getting enough engine go bye bye.

oops smack me
Quick retraction, A I noticed you said its an NA comp....I dotn quite get how your doin that but lets move on..my cars na dont know a ton about the turbos setup
B a friend of mines using a turbo at 9.5psi in his second gen tII he has stock ECU he says its ok to 11psi but he bought a fcd to be on safe side. He also has upgraded fuel pump, injectors and lines(rated at higher pressure) Though niether one of use get how a NA comp is delivering enough fuel for a turbo period. Maybe were just dumb.

martin.... are you retarded....
you said it was not fuel cut
but you also said you have not experienced fuel cut
you are in no position to say it isnt fuel cut when you dont even know what it is
either do what Ted suggested
or get a fuel cut defender
or me and my mad scientists will have to replace the piston rings you fried....
hondahater.... research vert ECU and T2 ecu and their similarities

yeah you guys are ridiculous.... Vert ECU has all the fuel maps for a TII, because it has the same ECU as the japanese Verts, which were all Turbo.
interesting little piece of info....
the Vert ECU isn't exactly an "N/A" ECU. it's more of a hybrid....
(and btw - don't tell me that i don't know what i'm talking about - because i have a Vert, and i was almost ready to do a full TII swap until the old N/A motor blew up and i bought my '91 and ran out of money.... sucks !!!!)

first of all you dumb ***, I have experienced fuel cut, I said it in my previouse statement. Maybe if you learned how to read. Since when does fuel cut sound like antilag or a two stepp? I have hit fuel cut in 2 or 3 different cars, and none of them were as described. The car usually bogs, or hesitates.

You know, I've heard something about the vert ecu's being compatible with the tII's however I know the rtek 1.7 chip doesn't work in the vert ecu so I kind of put two and two together to come to some sort of conclution that they are in some ways the same but in enough ways differant to where the rtek won't work with it. Just my oppinion though.

Anyways, thanks to all of you who have voiced your opinions, REted I will try unplugging the PS, even though I get the haltec tommorrow I wont get to install it till mid week. And if it was fuel cut, then sorry for doubting yall... Again thanks
ok i will take my 69 chevelle ss and spank it

But MARTIN, I believe Andrew is correct since you have an S4. Check your ECU...if its a N338, then I'd say you're more than likely hitting fuel cut. Get an FCD, problem solved.

Thanks, Thats the reason that I even put and swaped everything. Becaise pf my ecu. They been told me that I can use the n338, my is s4 so I got it. At first all I wanted a stock tii motor, therefore the reason as to why I didnt get a stand alone. Then I bought a car, so I just want to have this as my project car.... THanks anyways, I got the haltec already. Ill try to see if I disconnect the Ps if it still does it... Thanks all

you really need to take the Fast AND Fourious off REPEAT...did you try out for the movie and not make it![Smilie](https://www.rx7club.com/images/smilies/smile.gif)

just make sure you dont run 10psi in the maxima and make your floorpans fall out because your engine might surge and you wouldnt know what it is

Also, is that turbo even coolant cooled? Most of the horror stories I heard about the XS turbo's were due to them not being oil cooled and the rotary heat killed them.

Well I dont know about horror stories on this particular turbo, but I have only seen promising results....I have 2 of my friends with supras (mkIII) making pretty good power out of this same turbo, with the smaller back housing (they are only offered with a .68). Anyways, I removed the PS and the cut happens at the same boost levels. I shift way before redline ( maybe 5500 or 6k) and it still happens. I also noticed that right when it cuts out, the tach dies. Ever more making me lean towards the ignition cut...

Welp, at least you know it's not overboost fuel-cut. ![Smilie](https://www.rx7club.com/images/smilies/smile.gif)
So, that leaves too much fuel (excess gas wetting the spark plugs which kills spark) or the TPS is bad (check if WOT is not over 5.5k-ohms!).

I also believe its too much fuel... Today I hit the fuel switch to off, and the car kept running for like 8-9 secs. And the switch is connected right, I have had the switch on there for like 3 to 4 years and a few engines. I also notice that at idle, the manifold gets really really red, and its SS. Could the cut be from having the sec injectors wired wrong?

if your runing the SSAutoChrome manifold it's actually chromed steel
just a FYI their is a guy on honda-tech who had a master power "T70" and the compressor housing broke completly in half at the seam and it looked like it wasn't even cast together, it was glued
