2003 Nissan 350z 1.5jzgte swap
Hey everyone I am new to the 350z community, my name is Josh.
The main goal for this project is sleeper status with 400~ on the street with pump gas and 600+ on the track/drag strip with E85. Long story short, I use to be an owner of a 1989 Toyota Supra with a 1JZGTE swap. The car was stolen and found in pieces/chopped up. When I bought the car back the engine was tired and cylinder 4 was scored up, so I decided why not upgrade to a 2jzge bottom end for the build! 2jzge built bottom end CP pistons, Scat rods, ARP head studs/mains, King racing bearings,10-1 compression 1jzgte stock head 6 boost manifold Precision 46mm wastegate Tial BOV Stage 4 Collins adapter kit full kit with ACT clutch and aluminum driveshaft, etc... Wiring specialties harness Complete set of OEM gaskets(Tomei Headgasket 2.0mm 87.5 bore) used to bring compression down from 11.0 to 10.1 Gates timing belt Link g4 + storm black edition Injector dynamics rail with 1000 CC injectors Flex fuel sensor and full ethanol lines Walbro 255/450 Lower rad hose/upper FFIM intake CJ motor sports fuel return kit Precision waste gate x1 Tial BOV air fittings Power steering high pressure line Inter-cooler Oil cooler AC compressor/bracket BC Springs/Retainers Valve Keepers Thermostat housing 16x1.5 VVTI PLUG 2jzge starter Turbo 61/62 custom dual ball bearing 1.06 ar t3 Updated List of parts needed to complete the swap High Priority Inter-cooler-piping Cooling fans Throttle Cable Low Priority Oil cooler lines -8 Air Filter Wideband o2 sensor Precision 46MM waste gate Down pipe Modify manifold for dual gates AC lines Serpentine belt Here's some pictures of the car / parts https://cimg3.ibsrv.net/gimg/my350z....ba8fe821d2.jpg https://cimg4.ibsrv.net/gimg/my350z....77ea531e7f.jpg https://cimg6.ibsrv.net/gimg/my350z....139d9b1532.jpg https://cimg8.ibsrv.net/gimg/my350z....08d1538cd6.jpg https://cimg9.ibsrv.net/gimg/my350z....87588dcc98.jpg https://cimg5.ibsrv.net/gimg/my350z....6e6b578693.jpg https://cimg1.ibsrv.net/gimg/my350z....9bea8a3d0f.jpg https://cimg4.ibsrv.net/gimg/my350z....0cca37de8f.jpg 6 boost manifold https://cimg8.ibsrv.net/gimg/my350z....870ee79f6a.jpg Collins swap kit minus shifter(was shipped separately) https://cimg1.ibsrv.net/gimg/my350z....9806b73033.jpg https://cimg4.ibsrv.net/gimg/my350z....e3b4390e05.jpg https://cimg5.ibsrv.net/gimg/my350z....593b4f3720.jpg |
It's been done before recently and I suggest you find that thread (I'm sure someone will post it) and do exactly as he did.
do you have tig setup? do you tune as well? |
Hey thanks for the information, I checked all of those posts already. I am just torn between using a mk4 supra radiator or a 350z aluminum core and having the bottom outlet welded to the passenger side of the radiator.
No I do not have a tig welder ( my close family friend is a professional mobile welder). I will be getting Chris scemin from Spectrum Motorsports Solutions to modify the manifold and build the down pipe as he is building me a custom ball bearing turbo. I have the basic abilities to tune, I have done quite a bit of street tuning on my supra. That being said I am no professional and I have blown up a few 7mgte supra engines learning in the past. Once i switched to a 1jzgte I went full standalone and I learned a lot. I tuned it to 18 psi made about 400~ to the wheels with a 6266, I had that setup for about 4 months and the car was stolen. I did not get the turbo back but I got the engine and trans back, I think they took the turbo off and sold it right away. When it comes to tuning I will not go beyond my comfort zone, my comfort zone is low timing maximum of 18 psi of boost and keeping it on pump gas. So in the end I will be getting it professionally tuned, I am actually working on a base map with PC link software to run the car once the car is assembled. Sorry for the rambling =) |
You may want to pick up an inexpensive TIG machine as you will need to do custom mounts, intake, exhaust work. Having the ability to weld stuff whenever you want will be a big help.
Sounds like you have a good base for tuning ... I'd continue that by street tuning your fuel and tinkering (and I use that very very lightly) your ignition. I just jumped to the Link G4 on my VQDE/350z and although more complicted it's way more capable than my previous piggyback haltech. Shameless plug - but if you want to learn more about tuning High Performance Academy is a pretty good source. Its $19/month and/or per course cost but it's well worth it. Document your build for sure - you got a great start and I'm interested on how you do things and you are attempting quite possibly the hardest / most realistic build on this platform. |

This is going to be beautiful when completed. Keep us updated!

Will do sir! I am still waiting on driftmotion for 2 weeks to ship my full oem gaskets/ ARP Mains. Also it has been 4 weeks since I ordered my wiring specialties harness, and they still haven't started building it yet. On a positive note the Crank/dampener/pressure plate/flywheel were sent off to be balanced as the rods arrived at the machine shop yesterday. So engine will be ready in a week or two hopefully. They still have to bore out the cylinders drill out the oil feed line on the passenger side, Drill out the drain flange for the turbo on the front sump pan. I am probably going to get them to assemble the bottom end as well, we will see. I also ordered a new 350z aluminum radiator and 2jz lower rad hose. The radiator is just an ebay special, the bottom outlet needs to be welded on the opposite side. The 1jzgte water neck needs to be cut and welded as well....Lots of work to do. I decided to go with a 350z radiator so I didn't have to hack my front end up.

Some parts arrived and driftmotion finally shipped my order today! They can't get me 1jz non vvti exhaust gaskets anyone know a source for them? The parts pile is getting huge..... lol

On a side note, I am trying to explain everything in as much detail as possible. I noticed while doing my research that a lot of threads were lacking information in regards to this swap. |
Just ordered cj motorsports return fuel kit
|
Update, Parts list is getting smaller every week. I ordered the fittings for the tial BOV and precision wastegate air fittings/ clamp that were missing. I also dropped the radiator off at my friends place who is a professional welder and he is switching the outlets on the radiator for me for free! He will also be modifying the top feed off the 1jzgte head for the radiator feed, he wants to do it once it's in the car so we don't cut and weld and it's the wrong angle. Which is the smart thing to do honestly hopefully he can weld up a few bungs for me and a couple inter cooler pipes too! Also still no update from wiring specialties on when the harness will be finished, but hey it's no big deal, I'm not quite ready to start the swap yet. Still need a few more things and to save up some money for the downpipe/modify wastegate unless my friend will do it, but I don't wanna end up with boost creep when modifying the position of the wastegates.

In for updates. Looks like a fun project.

having the ability to slightly mod these components will be awesome. I switched my coolant hoses to AN-20 lines and it's a much better look/function.
great progress! Now for the update gaskets, timing belt thermal take intake gaskets and arp main studs are in!!!! And a bonus driftmotion found me a set of exhaust manifold gaskets. They are super awesome!! https://cimg7.ibsrv.net/gimg/my350z....4d3e87ab6a.jpg |
Quick update I am still waiting on the machine shop at this point, I have no idea why it's taking so long. It has been in the shop for almost 2 months. Some good news my cj motor sports kit and fittings are in at my PO box I'll try and grab it next week when I have time

two contradicting thoughts:

Yes 2 months is a long time, considering they have all the parts for the engine... Thanks man, I think I'm just being impatient. Been having dreams of the 350z 1.5jz hahaha |
Heads back from the machine shop

I have some good news wiring specialties has finished my harness and it has been shipped!
The bad news the machine shop has been working on the bottom end and we ran into a bit of a problem. We drilled out the oil feed hole, for the turbo on the 2jzge block. It leads to a empty oil gallery that has no oil feeding to the oil gallery on the passenger/exhaust side of the block. This is because that oil gallery feeds the turbo / oil squirters in the 2jzgte's but not the 2jzge's... good thing they caught this as it would have costed me a turbo!!! I spoke with Real Street Performance and they were nice enough to send me a video of where we have to drill into the block to get oil into that gallery! |
A quick update, i ordered chaser bays high pressure power steering hose. I haven't had time to pick up some parts at my po box.
