so lifegrddude, do you know how much hp you have? or can we get a video of this beast showing its stuff? just a thought, at 14.7 psi boost, its gotta be a wicked car, now i really want a turbo, but instead i build an na. d'oh

 

I'm in the process of doing the Z31 ecu swap. I think I can do most of it tonight & finish over the weekend. I was at 220whp @ 12psi before, with the 370cc injectors I hope to be around 260+whp.

LifegrdDude.... did you ever use the 370cc's w/o the SAFC-II ?

 

Shady, I have no idea what kinda #'s my Z is putting down at the moment. I'm guessing ~250hp or so. The only time I dynoed my Z, it was pretty much stock minus a K&N and a mild bump in boost. It put down 178hp and ~205 lb/ft of torque. I plan to dyno my Z eventually. I'm in the middle of doing some work so it's not even driveable right now.

Nismopick, I did use the 370's on my Z when I had the stock efi hooked up. I didn't use them on the Z31 setup until I got the SAFC because the Z wouldn't run at all with them hooked up. The motor would flood from the overdose of fuel.

 

hey nismo, wasnt that 220 hp with only five cylinders working correctly?

 

Indeed it was! I forgot about that. Did you see that dyno vid?

The z31 guys found that afc with a turbo will screw with the timing to much to make it desireable. I could be wrong though you sound like it working well for you. But check out this link at the top. Get an 88-89 N/A ecu socket it. download some software, buy a romulator and tune the factory code. I'm doing it and love it 420cc injectors and z32mas. the z31 guys on that site are really into with mas comparions, and other mas hacks. About 5-6 member put down over 400hp runing tuned 88-89 ecus.

Hey man, I would really like to see your 280zx turbo. It sounds like a pretty sweet car. That would be cool if you could post some pics of it.

 

dang, this thing been dead for a while, anyway Lifegrddude, how much hp are you running now?

 

He's not running the SAFC anymore... he's using a reprogrammed Z31 ecu. I think he's around 370hp??? That's what he was aiming for anyway.

 

Yeah like Nismopick said, I'm not using the SAFC anymore, but I did get down to the low 9's for the 1/8 mile. I was hitting 9.2's on average instead of 9.5's so there was some benefit to using the SAFC. Anyway, I'm hoping to have close to 300hp with the reprogrammed ecu on 1100 kPa of boost (~16psi). That'll be more than enough for a daily driver on the stuff we call gas here in Cali. I want to finish my exhaust before I go to the dyno, and I need to do a basic tune up. My distributor cap has carbon tracing and it's arcing like crazy. The SAFC is good if you want to monitor things too though, not to mention it was handy as a tach since my factory tach is a little off above 3500 rpm. 6K on the dyno (when I was essentially stock) had my tach showing close to 6300 rpm.
