Well winter came around and got bored and decided to finally update the current turbo setup on my maxima. I was running a log type manifold and just don't like it so slapped a 3-1 setup together. Will be making a new cross over pipe also as going to move the turbo a little and lower it closer to tranny for more clearance. Will be running a Holset most likely Hx35. Along with some 550cc. Upgrade from the 370cc which will go to her car. Also decided to build a setup for my gfs Maxima. Using set of stock z31 manifolds. Making 2 of these kits. Here is what I got so far still in early stages of the new build. Sorry if picture are bad quality taken in poor lighting with cell phone.
Here is my manifolds tacked up. Ran out of piping and waiting on turbo before start the crossover piece.

 

Would only let me put 5 pics per thread?? so heres the rest.



Downpipe is 2.5". Hard to see in pic but is about 1/2" clearance from starter. Will be running down under oil pan where stock goes once get some more material. Sorry for ugly welds welder was runing out of wire going to clean up and fix tomarrow when buy a new roll. That is on a 5spd tranny. Not sure if the auto would be different for clearance. Would guess its the same.

 

oh wow... you're doing 2 at once? I assume you're desiging both of them on the same engine, then just installing the 3-1's on your car when you're done, and putting the motor in the pic back into your gf's car?

also on the one using z31 manifolds... have you tried the clearance if you flip the turbo around so the cold side is near the starter and the downpipe comes out toward the front-side of the motor? i've seen that setup used elsewhere on a 3rd gen and they had plenty of clearance. just an idea.. dunno if you tried it already or not.

but ah, looking real good dude! i bet you could make headers (that FIT!) for the n/a cars as well and everybody would love you a whole bunch!

and THANK GOD that someone finally did the "i'm turbocharging my [girlfriend's] maxima [and updating my own turbo setup]" thread right... pics of the juicy stuff right off the bat

 

it's 5 pics per post, not per thread..

 

Actually that motor is just my mock up. Its hollow motor. Along with the trans I had a bunch of parts laying around and just slaped it together. What headers are the NA guys using that don't fit. I just got laid of so have free time and can start a set tomarrow if had some piping Is what I plan on doing (once I get my new bender) is make a package deal will come with headers crossover pipe and downpipe. Or if want to go with stock z31 kit will be making front motor mount for clearance.
I did try the turbo fliped other way. I did not like how I was going to have to route the exhaust. Here is what it looked like. I didn't take many pics in that postion. If someone wanted me to I could route it that way just to see might just do one out of curiosity.

 

well i personally know a 3rd gen VGT guy with the turbo oriented that way, and i've seen his exhaust routing and it's pretty nice. he posts occasionally.

as far as headers, the pacesetter headers are the ones that were made for the VG maxima (well, 'modified' from the z31, for the VG maxima).. there's been a bunch about that on here. so a good set of headers that fits would be a hit with the n/a guys. selling the turbo header/downpipe kit would also rock... but will it fit multiple turbo models or only the one pictured?

 

cool projects!! Do you do any fabrication stuff for VE or only VGs?

 

yup...all you need is a slim radiator fan and it's a perfect fit.

would people actually buy a turbo kit?
you can run whatever turbo you want...it's just the flange that's different.

 

you're not using any gas w/ the mig weld right?

 

I was started a list what I need to order for piping might go ahead and order enough for some NA headers. All depends how much cash I will have. First one will be Stainless steel most likely, thought it would look nice. Also got to refill my argon bottle. I just picked up a new rig and mini rig want to try out. Well I picked a turbo thats decent size so would be able to fit multiple turbos. Now I can take pitures with the Stock T28 of a z31 to compare. This turbonetics Was one I just grabbed of the shelve becauase Good for 350hp and would suite most peoples needs. Worst case say someone wants to run say GT3582 I can make and extension and will move the turbo over farther from the starter and such and possible avoid changing to a different motor mount. This down pipe is a 5 bolt flange which is most common any can be used.

Fabricate for any type of vehicle Honda Nissan Ford Motorcyles boats. You name it. The biggest difference is on the VE is flanges on manifolds are turned. Would be very easy to do. I don't have a VE motor to mock up on. Trying to get a car from someone but he just don't want to sell.

 

ya thats some ugly flux core Waiting on geting an argon bottle for my Tig rig.

 

wooo..TIG...nice

i was about to say your welder setting is a little "off" if you were welding mig w/ gas.

 

well I was fighting it on the back side is a real nice bead but running out of wire it acts all weird and wire speed fluctuates.

 

Well got some wire. Decided to make 3-1 headers fit my old crossover piece. So meant little cut here and there but made her work this is where im sitting now. Need to decide how I want to finish off the collector flange or just leave it how it is.

 

dont forget to put blow off vavle

 

Awesome setup!

 

yeah.... because he was REALLY gonna just... forget to put one on if you didn't remind him....

 

Oh really? Lol i cant read da whole thread on phone cuz my internet line is messed and i cant use da net on comp so i m using phone and all i read is the last post lol

 

The blow off valve will be going back on. Which reminds me still need one for the bike if anyone has a spare laying around.

 

last i checked the BOV goes on the intake piping....we're seeing pics of exhaust piping so where do you supposed he should put the BOV? are you referring to wastegate?

 

Think he is just saying in general to make sure I put one on. And also Bov is still on the car. All my charge pipe is still there.

 

ummm ok...well make sure you put oil in the motor then

 

Forgot to remind me to put internals in the motor.

 

blinker fluid?

 

blah, you no need no stinking pistonz!!!..

 

blinker fluid does exist...Friend in is 07 vette had fluid leak out of the turn signal switch. They covered it under warranty. Not sure what it does but it is there.

 

no pistons -> less compression -> more boost

 

nope i m not referring to waste gate i was talkin about bov and u r right it does go on the intake piping to reduce the turbo lag. Cuz wen u take the step off the race pedal ur throttle plate closes but turbine in turbo is still moving VERY fast and the air pressure from dat constantley hitting the closed plate and it gets damage wit time plus the air going bak to the turbine.BLow off vavle releases that air wen its comes in intake and makes dat cool sound lol

U can say dat..i jus said it generally....i didnt know u already have bov dere...gud for ur setup tho....
LOL

 

ah, another VG turbo going underway and convincing me to finish mine instead of a 3.5 VQ swap that Aaron is working on.

 

well there's one obvious choice

go get your 89 back and do one of both!

 

yeah, about my old '89??? last i heard from that car, my friend who i sold it to apparently sold it to someone else at his job and from there who knows where that car is at now? wish i did have it back so that i can do the turbo project and use my current '93 for the VQ project. but i also got ahold of a '97 which is sitting in my back yard now with the motor and tranny out of the car. im redoing the timing in my newly owned 4th gen alongside my 3rd gen as well. but i will still keep thinking about either going turbo on the VG or swap the VQ and either go turbo or supercharge it? but for now i have to settle for what i have. right now funds are really low so i have to wait.

 

umm... when I race, I need all THREE pedals, not a single pedal as you imply

and yes, I am sure we are all familiar with what a bov does...

 

how about boosting the VG in your 93 and doing a 3.5 swap on the 4th gen? it'll be easier overall because the VG has alot of turbo support, and the VQ-for-VQ (30de to 35de) swap is alot easier than the VG/E to VQ swap.

 

i wondered what is this thing?
thanks for the info.

 

yeah i thought of that too but i want to take on the challenge and actually swap in the 3.5 in my '93 and leave my '97 as is. it'll be:

'93 GXE - project car
'97 SE - daily driver with few mods
'08 335i - fun weekend car

 

looks good . i suppose if you still wanna do dat turbo thang, you can still make some pipes and stuff and turbo the 3.5

 

yes sir that was my original plan if the 3.5 swap came through and actually works in my 3rd gen.

 

I just wonder, who's going to ever do an actual VG turbo kit or at least a detailed write up including all necessary parts, recommended vendors/prices, pipe routing and fabrication specs, turbo placement, etc.?

 

I could do this...Only thing is so many options you can go, such has custom headers or z31.

 

I guess my idea is to have a way for beginners to the turbo process to get started with a fairly simple setup. I assume that using Z31 headers is the simplest way to go. As far as turbo placement and such, I'm not sure what else is involved.

Additional setups involving custom headers and other custom fabrication could be included in an additional write up, but I think it should be simple first.
