Well for the past week I've been working on a turbo for my car, and I finally got it running last night. There are a few issues with it, a rough idle, bucking/hesitation under part throttle, and sometimes a hesitation around 4K rpms under medium load. I have yet to get into the gas, I'm waiting to tune before that. Still though, the car is as fast now under half throttle as it was WOT when I was N/A. The turbo (T3/T04e 60 trim) spools a little under 3K. For now, I'm running 6 psi with just the wastegate spring. Ran into a few kinks along the way with the install, namely the oil pan leaking on the tranny side because of the half-circle gasket not seating. It was a pain pulling everything off again, but well worth it. Here are a few pics.

Let me know what you guys think!

(You'll have to excuse the welds, it was pretty much my first time welding )

 

i love it brad. if i get ahold of scott i will be down this week. i hope you get it tuned before then.
steve

 

looks great

i see the cartech FMU good choice do you have a FP gauge to see if its working

can you get a pic of where you tapped the pan for the oil drain ive got a good idea but would just like a pic to confirm

 

how much did you pick up the turbo for.

 

It was around $638 shipped from Full Race Motorsports

Subs, I'll try and get a pic of that soon, all I have now is the one showing the pipe that I welded in. I tapped it on the front side, I think it was between the 2nd and 3rd bolt holes from the transmission side. It is right where the support is on the engine, so the crank wont be throwing oil up the drain line.

 

thank for the help.

 

Love the max, where can i get a manifold like that, how much should i expect to pay

 

o m g this is freakin hot.. other than the RRFPR what else did you need for the fuel management? why dont' you use the SAFCII?

 

wow, awesome to see another turbo 3rd gen!
Question...your charge pipe looks VERY VERY close to the downpipe if Im not mistaking....I see there is heat wrap on it, but how did you manage that?
Got any under carraige pics?

welds look good....no biggie. great craftsmanship!

 

Thanks for the comments! As for the feed pipe, it took around 5 hours to make, piping the wastegate was kind of difficult. A shop would probably be able to do it in alot less time.



Thats it, just the rrfpr, nismo fpr, and walbro 255lph pump.

 

Thanks! Yeah, the charge pipe is kind of close, but there is probably 3 inches of clearance there. The downpipe is really close to the feed pipe though, probably 1/8" clearance. To take care of that I just tacked a metal plate to them both to keep them together.

 

very nice. keep us updated on that thing. love to see some dyno numbers after you tune it.

 

Very nice. love your piping. Much better than mine. We will have to get together soon

 

so how much did you spend on all of this? what kind of pipes did you use? mild steel? and what kind of pipes did you use for the pipes that go to the turbo? thanks and good job on the turbo =D

 

Brad...looks awesome. Where do you have your MAF sensor...and did you have to do some cutting on the bumper for the intercooler?

 

I'd love to see both your beasts. Your coming up to GLD Brad?

 

good stuff...very clean too!!!

 

Thanks Mike, I hope to see you at GLD!

My MAF is on the charged side, it sits kind of close to the turbine, so hopefully that wont cause problems down the road. The piping is aluminized mild steel, I bought the bends from jegs. I wouldnt recommend them though, the pipes were slightly crushed in the bends. Nothing major, but kind of a pain to weld nicely, there are lips on the inside of some of em. As for the price, I would say all said and done, with the gauges and all the misc. bolts and such, probably close to $3500.

 

heck yes! flippin awsome

 

larry, i am planning on coming out ot the burgh may. pm with what burrough you live in.

Steve

 

Very NICE on the turbo,the welding look 100x better than my first time weld,LOL!

 

slimer...dude i just moved...i am half hour north of philly now. i go back to pittsburgh on the weekends so pm me if you will be there on any weekend and we'll get together. 10 mins east of pittsburgh i stay w/ a friend on the weekends...called monroeville...its a larger suburb...you can see it on any map...or if you are in philly sometime check me out

 

Dont forget to take your pothole detector! Oh, and raise your car a few inch's. (used to live just south of pitt) Killer roads

 

yeah, on 376 comin back from monroeville i hit a pothole, bent an oem rim (which are thick as hell), watched penndot fill it while i was on the side of the road, tried to get a police report on it and they had no record

 

That is the cleanest VE-T setup I have seen to date. I love how you stuff the IC behind the bumper and front lip. Did you cut the lip and support? or just take the support completely off? Also, did you do it yourself? I didnt catch that part.

 

looks like the support is cut from the pictures:

My dad and a few friends helped me every now and then, its much eaiser to do the piping when you have an extra set of hands.

Yeah, the support is pretty well hacked up. I just found out tonight with Scott's help that the bend that I have right before the MAF is causing my rough idle. We moved it to the non-charged side for right now, and the idle is smooth. I do have alot more problems with stalling/backfiring now, I think its running super rich. The vented BOV probably has something to do with that also. This weekend I'm going to redo the intake piping and move the MAF to the straighter section of pipe, and move the BOV around. Hopefully that will clear some things up.

 

if your bov is before the maf (when its on the charged side) it shouldn't run rich when you release the throttle as it is venting un-metered air. however, when you put the maf on the non-pressure side it will act up when the bov opens.

 

cool so how many ve turbo do we have out there? only if i could post friking pictures.

 

Im curious as well....how many turbo ve's are there?

espimax if you need some free server space for pics go to www.photobucket.com then you can post pictures all day long

 

There are 4 that I know of... 4signs, Julio (had one), Maxtuned, and me.. are you turbo also?

 

cool thank you man for the free tip. and yes i'm also boosting away on my 93 se!

 

thats a very clean and nice setup...

 

Awesome, how long have you been turbo? I'd like to see some pics of your setup!

 

Look at the brain on Brad! hehe. Nice job man! I like it.

 

about 9 months now, but i blew my motor on dec. it got lean about 150+ mph on the turpike, now the motor is done up, but i'm still having roblems with the timing, the is 5 diferent chaings in this friking motor, it was droped 2 times now i just got it back this sunday and i'm getting the fealing is still not time rigth, today i'm going to put the jtw ecu back in the car and swith the 370cc to the new program ecu with the 550cc injectors and we will see what happend them, i will post some pictures today as soon as i learn how!

 

Update: Tonight I was able to get a rough tune in. I moved my MAF back to the charged side, since having it before the turbo was causing some major issues at part throttle. I tuned it to around 11.1 AFR, but the numbers were jumping around a bit. The part throttle AFR under boost is pretty rich, between 10.0 and 10.6, but I dont think I can correct for that since the FMU adds the fuel pressure regardless of throttle position. It run fairly well, still backfires sometimes though when WOT. It does that usually when the fuel pressure hits 80+psi, but sometimes lower. Hopefully correcting the bend in my piping before the MAF will solve that problem, along with the idle.

 

did you go to the dyno or do you have a wideband if so which one

you could lean out WOT to 12:1 which would still be perfactly safe and that could help your excessivly rich partial throttle

regardless it sounds like your making great progress which is good to here

 

Hooked of Phonics worked for me!

 

I'm using Scott's (boosted maxima) wideband right now. I'll try leaning it out a bit this weekend.
