XS Engineering turbo kit for our KA24DE...

[S14 Wannabe]

This is a post about our KA24DET build up and what has been done to this date. It's just a small write up with pictures and for you all that have experience with the build up of a KA to make suggestions to consider.

My friend just bought for $ 1,000.00 a complete XS turbo setup from a local who was selling it because he got an SR. This is what it came with :

Pics to be found here because I couldn't attach them :

What isn't showing is the ACT clutch. It turns out the T3 flange is wrong so... he sold it for $ 75.00 in perfect condition to a friend that posts on here also. It's from a Z31 turbo Z. So we looked at the T4 and there is tons of shaft play. It plainly needs to be rebuilt. You can hear rubbing. We were going to have it rebuilt by turbochargers.com but he didn't want that. Instead he is buying a T3/T4 from Turbonetics with a .60 AR and a 57 trim brand new for another $ 500.00 or so. I forgot the actual price. He ordered it last week and should get it in sometime this week. Along the way he also picked up a Greddy E-Manage with full software for $ 350.00. He has stated by Sunday he wants everything to be in and running. I'll post pics of every part of the build up and what I think will be the painful install of the E-manage. Hopefully the stock internals can handle 7 psi.

Much more pics to come after the weekend to include what he has bought since December. Sorry so late but this is an ongoing project. And where the hell is the "Post your pics/face" thread at. I have a new pic to share with you guys.

why did you choose the meltagate over the tial?

[S14 Wannabe]

It's just what it came with. I know, I know the delta gate is also known as the s h i t gate. Tial will be coming but it's not first on his list just yet. A couple of friends are still using deltagates with no problems yet but trust me, Tial will be in there at a later date.

And here is a pic of me being stupid because I can't find the post your pics thread... yes I know... I was a little too happy. This was at a party and I was a little tipsy.

If your friend hasn't ordered his turbo yet, tell him the 50 trim is much more efficient than the 57, check this thread out: http://www.nissaninfiniticlub....49195 Other than that, good luck with the buildup!

[S14 Wannabe]

Thanks I'll definately show him that thread.

I got the T3 hahahahahahaha!

[S14 Wannabe]

Yep.

Uhh? Does he realize if he uses a T3 turbine, it will locate the turbo differently? The XS kit is built arounf a T4 with a on-center turbine. Both the downpipe and intercooler piping will not line up directly with a T3/T4. The XS kit also uses an elbow that is welded onto the compressor outlet. Your friend will need to have one welded onto his compressor as well. Doing this carefully may get teh intercooler piping to line up if you clock the compressor housing correctly. But he will definitely need a new downpipe.

If he can, I'd probably make sure he at least thinks about using a T4 on-center turbine section instead. It will make it much more of a bolt-on affair. But I doubt he will have it done this weekend. Finding that 90 degree elbow to weld onto the compressor outlet is not necessarily easy. It took me a week to get mine when I had to replace my turbo on my XS kit.

Ooooh, thats a good point, I'd totally forgot about that!

Yup. We had the downpipe already made and fabbed to fit onto the flange. As for the intercooler piping, it fits. Thanks though for the concern. I would have hated for that to happen while we were working on it.

Update:

O.K. I finally have my own computer at home so getting pictures of our projects will be a lot faster than usual. We decided not to wait on the new T3/T4 turbo and to go with a T-61 that was on loan to us. We started at 5:00 p.m. and ended at 2:00 a.m. I got sick because of this project but overall it was very fun.

What isn’t shown is the E-manage. That took all but 10 minutes to hook up. My friend that owns this car is an audio installer so this was cakewalk for him. Next is tuning from someone. So far the car is starting to lean out because the injectors haven’t been replaced yet. What’s next also is going to be a bigger better fuel pump (preferably Walbro), bigger fuel filter, boost controller, and actually putting on that custom intake mani. More pics as more parts come in.

The car runs great though, and has already seen it's share of kills only on 4 psi.

[912.0turbo]

Yeah that KA-t is quick.I messed with him a little and I think he would pull me. Cant wait to up the boost someday or get an SDS.

GReddy E-Manage for $350 sounds like quite the deal. Where'd ya get it?It's like a bigger/better S-AFC, correct? Wha all does it allow you to do/control?

Nice setup btw. And send some <3 to the young lady in the picture for meh.

Edit: Well it seems MVP wants $309 for the E-Manage but then another $98 for the "Software & Support Tool." =\ Then optional pressure sensor, ignition, and injector harnesses. Damn...With the E-Manage and Software, would I still need an ECU Retune for larger upgrades like Injectors and bigger Turbo? Anyone? Teach meh!

The E-manage he got for $ 350.00 came with all three harness' and software. A friend has had that E-Manage for awhile and just decided to get rid of it because he is going full standalone. Yes you would need the E-manage to be tuned everytime you get bigger stuff however, we talked to the tech for the E-manage and he recommended not to go bigger than 470 cc because of mapping issues. He said you could go bigger but since the parameters in the E-manage are set, something in the software will go wrong. At least that's what he told us. He said whatever the mapping either it will run lean, rich, idle wrong or whathave you with what your running. I'm sure you can run bigger but something won't go right and that's something we didn't want to chance. We were already looking at the software/interface over the weekend and the idle control (to keep the car from dying at idle a problem we are currently having) looks to be pretty easy to control but the rest is going to have to be done by a tuner here because none of us know how to tune. Also none of us own a wideband 02. The install was easy though, I have to admit. Good thing we didn't pay for it to be installed.:pface

Back to basics guys…[IMG]http://upload.houston-imports.com/uploaded/Chae's Kouki2.jpg[/IMG]

So a couple of days ago we noticed that the car was starting to lean out. It was really weird considering that the car was running rich as hell just a couple of days before, so he decided to drop in the 300ZX TT injectors that he had bought from a friend. The injectors were too much. The car was way to rich. You could literally see fuel coming out the exhaust. The computer (I’m guessing) didn’t know how to compensate for the fuel so the car was dying on boost. We decided to give the anti stall a try again from the E-manage to see if we could get he percentages right.



We couldn’t do it. We tried and nothing (none of the percentages entered) was taking the right way. We then thought it might be the mass air sensor not telling the computer to compensate for more air. Tested the mass air sensor out and the mass air sensor was fine. Too much intercooler piping and not enough air getting to the intake manifold was also another theory. Then a friend said “Hey take off your cone air filter.” So we took off the filter to the turbo and held it to the light. Yeah, it was clogged. I mean so dirty absolutely no light was penetrating through. We bought a new filter and the car was good as new running a little rich still but nowhere near as bad as described. Yes the car still dies every now and then on high boost but that will go away as soon as we find out how to tune the stupid E-manage’s anti stall program. So, if any of you can give input on how to just tune the anti stall please let me know. Someone else will tune the E-manage but we just want the car to stop stalling.

The reason people say that you cant use bigger injectors with the emanage is not because of some limitation with the emanage software, its just a physical limitation of the injector itself. With huge injectors, the emanage (and anything else) can do its best to trim down the fuel at idle, but with such huge nozzles, it becomes more and more difficult to spray the tiny, precise amount of fuel that you need to get a good idle. Imagine trying to fill a thimble with water poured from a huge bucket. At least thats what I understand from my reading about the emanage... and I've done a lot of reading..

[S14 Wannabe]

You're exactly right fiznat. Great explaination. Now help me figure out this anti stall.:pface

[fiznat]

schwing!
