350Z Twin Turbo Prep - Fuel System Upgrades
HTML-код
- Опубликовано: 21 май 2018
- In preparation for the turbos, we're installing the AAM stage 1 fuel return kit as well as an upgraded fuel pump and bigger injectors. Oh and an intake plenum spacer as well just for the lols.

“The fuel is the pretty damp innit” gold
happy to see some new build video's. I like the driftcup video's as well. But I also like these technical build video's very much! :D
cheers, glad you're enjoying them
You should really upload more often because I have a '08 Z & I really enjoy watching your videos & learning more shit! Thanks!
I like your workshop vids and interested to see what gains you might get from the mods you have just done!
Can't wait to see the result.
This video was helpful thank you!
The reason for the plenum chamber being that shape inside and having the pipes bending off into banks of 3 on either side is to do with tuning the air flow. You can imagine the inside of the pipe is equivalent to the length of a trumpet on an ITB. Different lengths cause different changes in low down torque or high end power to due to differing resonant frequencies of air flow at different lengths (like a trombone). So this plenum with have likely been tuned for maximum driveability, from memory the DE or Rev up engines are quite torque heavy, whereas the later HR is higher power and a bit lower torque probably due to changes in the intake system.
Oh, and I'm going for 250 whp after the remap
Great video. Would be cool to see even more detail/work, but this was still quite nice.
First? Looks nice and bright in the workshop.
Nice video man. Safe to say you weren’t sponsored for that fuel kit with what you were saying 😂😂
haha no, never had any sponsored products in my life
Thank you for this video. It gave me a good idea on what to expect with my fuel return system. Single turboing my vq right now and I have a CJM return kit. Quite a bit different than this one but I think it's generally the same concept.
hey dereck! I just order a CJM s1 full fuel system, how was the install and did it work good
@@tysni3781 The install was pretty straight forward but it will take some adjustments to your stock fuel bucket. There are some guides online that are kinda vague but if I can figure it out I think anyone can lol
Really enjoy your vids, especially the build parts. Feels genuine and not so uptight as most of the channels out there.
I'm in the process of travelling to the Uk and pick up a Z myself. hopefully the upcoming weekend if all goes well.
Any pointers of where to start, If you would have done anything in a different order if starting over?
As of now I feel like the way to go is to start with rack spacers, coilovers, diff (has a nismo unit now which is supposed to be better than the standard unit and adjustable but idk)
then weight reduction and hydro. And a bunch of wheels and tyres ofcourse.
Cheers mate, keep it up :)
cheers, glad you enjoy :) as for the 350, yeah just stick coilovers on it and rack spacers (although I didn't have rack spacers for the first 6 months and it was still fine). I'd probably keep the nismo diff if I was you but yeah the stock handbrake is useless so if you want to be able to use a handbrake you're going to want to put a hydro in it. The other thing is the stock seats are pretty bad so look at getting some bucket seats if possible. Stripping out the metal and plastic stuff behind the seats is a good idea as you get way more room and save a bit of weight, but it does take a fair amount of work to get most of it out
Yeah buckets are included in the weight reduction plan. And the not flopping about in the cabin plan...
I have managed without handbrake corrections so far on previous cars, or had terrible e-brakes so that I have not been able to figure it out yet haha.
But yeah the hydro will come eventually. Did the metal wall thingy behind the seats affect the rigidity much when you removed it? Or did you feel nothing?
Trial and error will make this happen, and end my life economically.
I made 301 with plenum spacer, decats and cobra cat back, up at tdi north (2003 350z)
I wish that someone would show a full tutorial on how to do this job because it can definitely tend to get confusing.
Good Vid !
I'll go with 292-296 when mapped.
good guess, I'm thinking something similar
Yeah looking at the Plenum your motor looks quite healthy, not eating too much oil :) minor mods and better fuel with a map should see it near those numbers. Fingers crossed you may even push 300.
i cant waite for the results ! also man i miss that r8 and btw we have not seen the gt86 nor the m4 in a while .
yeah I'm not massively keen on the gt86 now after drifting the 350, mainly because the steering feels so weird in the 86. Trying to decide if I should keep it or sell it..
if it is seating you may as well invest the money elsewhere
Evening mentlegen...
You didn’t have to drill a hole in the new pressure regulator for turbo set up?
in my z my fuel pressure is like 35 psi when the car is at idle and my widebands read too lean it could be a bad fuel pump ?
Could you show us or link the items you bought? Thanks 👍🏽
I want to do the same but have no one who knows about it and research does only so much. Keep up the great vids
its the AAM Stage 1 Fuel Return kit
I just got the dw200 for my z but it doesnt seem to fit, it doesnt go in far enough to put that plastic end piece back on, any suggestions?
oh yeah you have to file the notches on the plastic part that the pump sits in. If you look at any of the guides online for how to upgrade the fuel pump in a 350z you'll see what I mean
I thought one needed to modify the swirl pot ( jet) in the fuel pump assembly to get the pump to make the correct pressure?
Wasn't aware of that to be honest, but just done a bit of research on it. Seems like most people say its only if you have issues with the pressure at idle being too high, but ours seemed fine and obeyed what we set on the FPR. Will keep an eye on it though and see if the tuner reports any issues when they map it
ChrisDrift thanks for the reply! Upon further thinking, I think what I wrote only applies if one keeps the factory FPR in the pump, and you guys replaced yours. Either way, great videos!
315 at the flywheel
I reckon you might have voided any warranty now mate. Just FYI ;)
nahhhh
Why did you go with the VQ35DE vs the better VQ37VHR? Twin turbo on an engine that already burns oil confused
cos I have a 350z not a 370z?
I think he’s talking about the vq35hr
that aam fuel return any good? I’m planning on buying as well
Seemed to work fine while I had it yeah. Eventually got rid of the stock tank when I went twin turbo cos suffers from fuel surge due to it being a saddle tank. Still used the fuel rails and fittings from this kit though
Considering it's just a spacer, and not actually the lower plenum spacer, your gains aren't going to be much at all. Since I don't know what your numbers were prior to these mods, I'd guess you'll only be seeing 10-15hp
well that's the thing, I don't know what power it was making before that lol but yeah not expecting the plenum spacer to do much at all - like I said, it was just a case of may as well do it for how cheap and easy it is. Hopefully when we go FI it will make a little bit more of a difference but we'll see
ChrisDrift I’m sure once you’re FI, the spacer will play a much bigger role in power gains. For what it’s worth, the lower plenum really wakes the VQ engine up. I guess if you’re going to be turbo though, that will wake it up too 😂
can you put the links to the stuff you used plz
I'll be providing a full list of all the parts used in the turbo build at the end, but yeah for now it was just the AAM Stage 1 Fuel Return Kit and the Motordyne 5/16" Basic Plenum Spacer
Where did you order your items from?
Think I ordered most of this from Tarmacsportz.co.uk
Why does everybody use the same annoying back ground music for youtube videos
this is literally the only video of mine where I've used music like this lol chill out
@@ChrisDrift i mean your videos are totally great its the background music i hear it in so many videos it chaffs me but your videos and your work is immaculate
de motor rip
rip?
