16G install finished... Impressions thus far..

[RuBiCaNT5X]

I just got finished installing my 16G this weekend. Started on Friday after work and finished up on Saturday around 7:30... Overall it took about 12 hours with most of the work being done solo. My friends and family pitched in here and there, but overall, it was a success. I will say this, there were a few bumps in the carpet but not what I expected. The water lines which were my biggest fear hardly needed to be bent at all which was good. The real bugger was the oil return line. The holes were a pain to file down, but eventually they got there. Once everything was assembled, checked for leaks, no problems at all. I will say this, Purolator oil filters DO NOT fit an RnR O2 Eliminator downpipe. I had to run to Valvoline and pick up one of theirs because they are about 1/4 to 3/8ths shorter than the Purolator.

Driving... I downed the boost from where I was (15psi) on the T25 to about 12 or so to be on the safe side. First thing I noticed was mad boost creep. I hit WOT and it would go from 12 to 13 to 15 to 17 at which point I let off the gas. Boost spikes were not prevalent all the time as it seemed more random than anything else but that's first impressions. Also since my automagic has such sloooooooooooow shifts, I had boost spikes of up to 20psi for a second or two. I got a shift kit waiting to go in so hopefully that gets cut down a bit. Other than that, it's a tad slower to spool than the T25 (shocking, I know.. ) and has AWESOME top end power. Another thing I noticed, and maybe it's because I have an AT, but the increase in speed wasn't that noticeable from the T25 at first. I think it's because of the lack of the jerk back and forth when shifting and boost is built and dumped. Again, those are my frist impressions. I am planning on upping the boost tomorrow to 15 to see how it runs...

Just a tad out of my driving range... I bought the Slowboy 2G install kit. Some things to watch out for. The most outstanding thing with their kit (which is a RRE hacker/tweaker kit) was the J-Pipe. It was welded very poorly on the compressor outlet side and had two pinholes on one of the seams. I had to take it to a friend to have the holes filled. Second thing, the bolts that attach the return line to the T25 are BIGGER than the holes on the 16G return line side. I had to use the bolts that fastened the stock oil feed line to the engine and turbo supports. I lucked out. Any other tips you want, or questions you have, let me know and i'd be happy to answer them as best I can...

yup, you need two 10mm bolts to attatch the oil return tube to the turbo. in some of the pics I've seen of 2G install kits, these aren't included.

Good review. I'd be interested to see how it feels after the shift kit-- you're gonna go black spring, right? Also, what kind of ATF are you using? I've had good luck with B&M TrickShift, both regular and synthetic.

I haven't changed the fluids yet because I haven't needed to. The car has only been in my possesion since last August it's stored over winter too. I'll give the B&M a look.

Yeah, definitely do a fluid/filter change when you can. It helped mine a lot the first time I changed it after I got the car last year.

Im interested in this project, please post your progress.

I would install a new bigger tranny cooler to go with that A/T tranny.

Once you set the boost to 15psi, your boost creep should go away. I just went through this about two weeks ago with my Big16G.

Update:

I redid my end clutches and those are solid now. I attempted to do a shift kit and that didn't work out so well. I had it installed into a 98GSX VB and it ended up not working out when I swapped mine out. As for the boost creep. I have it set to 14 now and it will still creep upwards of 18psi. Not a problem. If the shift kit ends up working out, I am going to add an SAFC2, 550's and a new upgraded SMIC. It's a daily driver so I am not going buck wild with mods. Modding an auto to begin with is crazy. Anyway, if I get a shift kit installed, I will let you guys know how much of a difference is makes.

Not necessarily. Modding an A/T AWD isn't nearly as crazy as doing a FWD A/T. Making a fast FWD auto is pretty frustrating since there's no LSD, for one thing. Spinning one wheel gets old-- fast. I'd swap my FWD for an AWD auto in a heartbeat.

When I was first setting my boost controller, I set it in increments. At 14 it was still wanting to creep to 16-17psi. Once I set it to 15 the creep was gone. Just try messing around with it a tad. It doesn't sound like the creep is nearly as bad as it was, but if it's inconsistent it will be harder to tune correctly..... Good luck with it.
