So here's my last thread, and specs on my current build.
http://forums.nicoclub.com/zerothread?id=207038

So now i'm putting the 810cc injectors in place of the 400cc, the GT35 in place of the T3 Super 60, and a tuned enthalpy ecu. I'm going to run somewhere around 12-15psi on my stock engine until my built motor is complete, or the stock one blows up.
The built motor will consist of:
Turbo 240 Sportsman Rods
Super Tech 9:1 comp pistons
Block is decked, hot tanked, bored over and honed
Balanced rotating assembly (flywheel, crank, crank pulley)
Metal head gasket
ARP Rod bolts, ARP main and head studs
Rebuilt head, ported and polished, 3 angle valve job with '91 cams
New OEM timing kit, oil pump, water pump etc.. basically replacing everything

I have to replace the 5 bolt downpipe flange for the turbo, make a new hot pipe since i'm coming out and around the p/s reservoir instead of straight down like before, also making the hot pipe 2.5" instead of 2" for the bigger turbo.
But for now here's a few pictures of what it looks like at the moment. Take a look at the link i posted at the beginning of the thread to see what has to be changed.

KA-T why settle for anything less?

I need to still move the p/s reservoir, and make my new hot pipe. As well as get my ecu tuned, so I can use my 810cc injectors and up the boost. But for now, it's running 12psi pretty good with 400cc injectors. Here's some more pictures.

a little dirty

p/s reservoir is pretty close to the compressor

So, one thing I noticed, which is probably normal.. I go out and tune during the day, and get perfect 12-12.5 afr at 12psi.. then I go out at night, when it's about 20 degrees cooler, and they hit like 13.5 afr.. is there any way around this with the SAFC II or do I just need to tune when it's cold out.. I'm getting my ecu tuned soon, but for the time being.. I drive during the day and night a lot.

Try opening them up some, but I doubt you are going to get much more fuel out of them..

It shouldn't really lean out at night as the MAFS should read the additional air coming in and add fuel as necessary..

That got me pretty good afr's during 70 degree weather in the day time at 12psi. Then last night I went out, same tune, and it was bouncing from 13-14.5 afr @ 13psi.. so I turned it down to 10psi and it held pretty good around 11.5-12 ... so I don't know..

I don't know what I should do to tune. I have 810cc injectors just laying here, everything is ready to go. I'd like to up the boost to 15psi and acually get a decent tune instead of this safc. Tuned ecu seems the easiest route. I'd like to go with MS II but I don't think that would be a good idea for me. This is my first car that i've worked on. I've done all the work. I've never driven a turbo'd car, or a fast car for that matter. So this is quite the accomplishment for me so far. I just don't want to blow my **** up. haha.. if I do, I have a built motor waiting to go in.. as soon as I get my rods.

So basically, what would anyone recommend I do for tuning? With a tuned ecu I wouldn't have to get it retuned with my new engine, because the only difference would be compression.

Buy an ECU tune... It might not be 1337 hax like MS or any of the other DIY methods, but at least your car won't blow up.. Esp for the first setup, you need a good experience or you'll get out of Nissans..

Boost hits really hard.. it's weird at first, because you floor it, and it just kinda goes like stock then about 4k rpms it hits 12psi and you have to shift pretty much immediately, it's fun... As soon as I get my ecu, and put my new injectors in, in about 2 weeks i'm getting on the dyno and going to push about 15-18psi.. I hope my stock motor doesn't blow.. it's never been touched beyond the valve cover.

Also, since you arent doing anything for timing...ahem...you're asking for trouble !!!
Proper ignition timing (retard) is more important for preventing detonation than having a rock solid AFR...

Sounds like a pretty insane top end setup though. Good for highway pulls!

btw, check the link in my sig for a short video from last night... me doing a burnout and some little donuts, it was pretty wet out though.. :\ and a video of my friends STI doing some too..

my wheels look like they have positive camber going on.. lol.

yes the front will be lowered... yes i have sideskirts.

here's the link, check my sig for the other videos.

here's my new hotpipe setup.. ditched the 2" steel crap for 2.5" aluminum and different route..

no, i haven't driven it yet. I have to get the piece that connects to the intercooler welded.

I finally got my Turbo240 rods in, which means my engine should be back from the machine shop next week. So i got started on tearing into my car again. We pulled tranny, drive shaft, and also dropped the rear subframe so I can get rid of this damn HICAS crap first. Then Shawn (wild_maxx) and I pulled the engine, tore it apart today so he could use the head/block for his KA-T build, didn't take us long at all.
so here's a few pics. more to come as I clean things up and such.

engine bay is super dirty and greasy.

HICAS bull****

No HICAS bull****

pile of old stock parts, exhaust, random stuff..

PS. I lied about running 12psi. My gauge said 12psi, but I put a friends in and i'm acually running 8psi. My gauge was way off. So 8psi was basically maxing the 400cc injectors with the new turbo.

"is it a big one?"

So I didn't get too much done today, I acually didn't really plan on doing anything, until I looked at the engine bay again and saw how ****ing dirty it is.. so I started cleaning it.. I got the fuse boxes and crap moved out of the way, and other random stuff.. and started going at it.. here's after about a half hour of cleaning it.. it's gross..

hopefully tomorrow will be a much more productive day. I need to finish removing all the hicas stuff from the rear, and install my eliminator bar, and vlsd..

before I started today..

after mounting fuse boxes and wires

and the daily driver

The bay looks good man... any word on when the engine will be done?

here's a pic of the hicas eliminator bar i just got done installing.. the tie rods were a ***** to get out of the rear steering rack.
