Hey everyone! I'm back from Georgia. I picked up my jdm vg30et along with my friend's vg30det. Payed 500 for mine and my friend payed the same for his. I'm going to start getting the engine ready to swap over and it will hopefully be done by the end of november if i can get the stuff to do the swap. Only problem i am seeing right now is the pipe piece that is directly off of the turbo. It runs right where my start will be so i'll have to get something custom done there. Then there is just swapping a bunch of maxima stuff to this engine and putting all of the wires together and getting a turbo ecu, which is cheap and easy on the z31 site. Anyone that has messed with these engine know what i could do about that exhaust piece? Thanks!

 

finish the swap in a month....hmmmm, trust me from experience, it doesn't work like that. you might have the motor in in a month, but completing it, I douubt that!

 

and what exhaust piece are you talking about??

 

All I can say is good luck. You are in for a much longer and arduous time than you think, my friend.

 

1 month

i take it a shop is doing the work for you then?

 

i don't have to screw with any of the intake piping which will help out a lot. most of the work is just swapping needed parts off of the maxima engine to the 300zx engine. if i get the ecu and clutch soon it can easily be a month but if i can't find the ecu it will be a while.

 

he`s talking about the Pre down pipe on the the turbo.. it contains the waste gate flapper inside it.. i know how to get passed that.

mtcookson: but its gonna cost you a few bucks. i say 50 dollars.

 

ummm...it's a bit more then that but have fun

 

I take it you are you just gonna run a low boost, non-IC setup and use the JDM cast iron elbow?? radiator fan clearance is an issue as well. good luck...

 

Believe me when I say the swap is not cheap if done correctly.I may have jumped the moon with my setup but if you are staying with the stock turbo and are using the z31 wiring harness then the z31 computer is possible.If you are using the maximas wiring then that z31 ecu will not work.Be realistic about what you want from the swap
and then take it from there. I hope to stir things up a bit for all 3rd gen owners very soon.

i'm going to throw the engine in with stock everything, get the z31 harness and ecu then be done with the engine for a while. i'm going to then get all of the brake and suspension mods, then build up the tranny, then finally build up the engine.

 

ok, i finally found the correct term for the pipe i'm having trouble with. it's the o2 sensor housing. it looks like this:

 

Here is my $.02, I'll assume that part had a gasket on it. Why not find some metal that is the thickness and trace the gasket around it. Next take it to a machine shop or somewhere that can cut it out. Now you have a template, then you can get a premade 2.5 or 3in (if space allows) bend installed and have a bung welded for the o2 sensor. BTW I don't know if a US Z31 o2 housing would fit. One time I got a NA Z front exhaust manifold for my maxima and it didn't fit. Mine would curve to the left (facing the engine) where as the Z would curve to the right. It almost hit my tranny . I'm sure you'll find some way of getting it to work.

 

i think i already told you? Pre Down pipe?

 

yeah, the guys on z31 called it the o2 sensor housing which made some more sense. either way, thanks for the info. what exactly can you do for 50 dollars?

 

tell you how to drop the motor in so that housing wont hit the starter

 

i think already have everything figured out. thanks for the offer though...

 

its very possible.

 

You guys need to quit being so negative. If someone says anything that hasn't been done before, its instantly "You'll never do it" "You moron, don't even bother" and so forth. If someone says I'll get it done in a month, just say, 'hey, good luck man, I'd like to see how it turns out.'

Just what I observe.
I personally think this project will be a challenge, but it should be worth it to find out whether it truly will work or not.

 

STFU Noob.. this is maxima.org hahahaha

 

considering the fact he's having to ask questions like this, it's going to take him a loooong time to get all of the stuff done. I'll put my lunch money on him not even having the piping done by the month's end, let alone the ECU wiring and actually having it in the car and running.

 

1) It's been done and some of us around here really do know what it takes to get a VG30ET into a max

2) Like Matt said the wiring and piping is the hardest part and if he's doing it himself then it's going to take longer than a month

 

Ok, It's fairly obvious that I've made a huge mistake by expressing my own personal opinion. I should think further before making light of anything that I feel. I am also aware this will not happen in a month, but most people prefer to burst their own bubbles when they find out that things just dont fit, and so on. So, thanks mykiszm for pointing out that I'm a complete retard and I'll just keep my personal thoughts away from the 'public forum'.

 

the piping is the EASY part. it's like building your own puzzle. you have a box full of chunks of pipes that will all fit together, and all you have to do is stick the engine in the car and start tacking pieces together until you get to the back end of the car. ever notice how many guys in muffler shops can't even read?
try not being able to read when you're installing a new ecu and trying to get allll the sensors hooked up correctly.

 

Seriously, rewiring a harness is NOOOO JOKE. It takes an experienced person DAYS to to a harness for an engine swap, and that's if they have done it a few times. You may have the know how, but it is truly one of THE most time consuming projects you can undertake with any automobile.ANd it has to be right and quality or nothing but problems will arise. I've seen a number of swaps that required this kind of work and all of them took at least a few weeks to wire and a few weeks to troubleshoot. But who knows, a maxima may be easier, these were all honda's and a 240sx. Good luck and I hope it really gets done, it would be cool.

 

Matt, didn't you already lose your lunch money already LAST month??

 

are you talking about exhaust piping, matt? i'm just going to have an exhaust shop do that. the one around here is really good. if you are talking about the intake piping for the turbo, i don't have to deal with it the way this engine is set up.

 

just stop post whoring.. and go get that engine in that maxima.

 

mtcookson...YOU DONE YET?!

pics? dyno? time slips?

(i'm not talking about a pic of the intake manifold in your sig either)

 

 

hmm.. is there a difference in the JDM and USDM turbos? or w/ the z31 t3 and the t25? cause my turbo has the wastegate in the DP adapter, where this one does not... just curious..
