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
https://cimg3.ibsrv.net/gimg/my350z....b0b4c30003.jpg https://cimg7.ibsrv.net/gimg/my350z....94c3f431d3.jpg nothing exciting really |
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.
|
Another quick update ordered a CX racing 3 inch core intercooler and 18 row oil cooler. Still no word from the machine shop on the status of the engine, Wiring harness is scheduled for delivery tomorrow. Also I have quite a few parts waiting at the border for me to pickup, just haven't had time busy working 6-7 days a week to fund the swap!
|
Just curious - why CX Racing for the IC? What oil cooler did you buy?
Good stuff! |
Cost effective basically they seem like decent quality for the price the oil cooler is also CX racing.
This is the intercooler I bought https://www.cxracing.com/intercooler...h-inlet/IC0022 Here's the oil cooler https://www.cxracing.com/oil-cooler-.../OC-248-19-AN8 |

They do make some nice harnesses, Just wish they would make a stock tuck harness for a 350z.

I ended up making my own … A good winter-time project and it came out better than what Nissan plopped down. Not impossible but a lot of documenting what wires go. Also got pretty good at re-pinning connectors. The nylon weave and heat shrink weren't too expensive and I ended up buying some crimping tools and crimps. I had an extra harness on hand and I ended up purchasing another harness so I could extend & match wire colors to the highest extent possible.
|
I made the last harness on my mk3 supra with the 1jzgte. This time I chose to use wiring specialties for maximum reliability as it's a daily driver at the moment part of the reason I have not started pulling it apart yet. I am dying to get started on this project we are almost there just a few more core components and I will be starting it.
Thanks guys for the replies etc.... helps me keep pushing forward! |
Oil cooler, intercooler, power steering line are all in

According to the machine shop the engine should be done this week.

Buying a replacement engine for my 03 DE
My 03 DE is manual and I’m buying an engine from an 04 automatic is there any difference in the engine at all or can I just pull the engine out and swap the other in?

Just a quick update bottom end is complete. I didn't expect it to be so much so I probably wont have it for 3 weeks.
|
Can't wait to see this!

I am so excited for this friday, I will finally have the block back from the machine shop. In the following weeks, I can finally start to assemble the engine. I just need to save some money for a head gasket, and then the engine assembly begins.
|
off the top of my head - things you may need (if you haven't gotten them already) for the rebuild process -
assembly lube heavy weight oil (like a 75w weight for things that you can't get assembly lube on but still need some lube for initial start-up) a oiling can vasoline (I used assembly lube) to pack/prime the oil pump head/main stud thread lube RTV (may want to consider a few different types - such as black for just about everything, water pump RTV for anything that seals up against coolant, high temp for anything near the exhaust mani, etc) antiseize paste Loctite red / blue thread lock/seal flush oil and/or break-in oil extra filters coolant & distilled water trans fluid (if needed) clutch alignment tool |

right on! I was able to purchase most of this stuff ahead of time but you forget one thing and it stops the train. I also live about 25minutes away from the closest autoparts so I tried to get everything I needed up-front.
Great overall progress - cant wait to see more! what did you set your oil bearing clearances at? |

Great overall progress - cant wait to see more! what did you set your oil bearing clearances at? Bearing clearances are factory spec the crank was micro polished. The block was in mint condition, didn't even need a rebuild. For reliablity purposes I wanted a forged block, because the vvti rods are known to give out at about 600hp. |
I'm just curious - what's factory spec on your block?
I ran mine down to .003" as it's rumored this is (strangely enough) what big number supra guys do. member TCode also advised between addition heat expansion and flex it's wise to get closer to the top end. Subsequently, going to a 40 weight oil. |

Engine is back from the machine shop. I started to assemble oil pump. Etc...

Some more progress, while waiting for the head gasket
https://cimg3.ibsrv.net/gimg/my350z....6093986f64.jpg https://cimg4.ibsrv.net/gimg/my350z....1213a25941.jpg https://cimg0.ibsrv.net/gimg/my350z....c6a08fafc1.jpg https://cimg1.ibsrv.net/gimg/my350z....f02149232a.jpg https://cimg2.ibsrv.net/gimg/my350z....1c06e55699.jpg |
So some progress test fitting the manifolds checking clearances etc... while I wait for the head gasket to come in.
There will also be another delay on the build as I think I am going to get some Brian crower springs and retainers, because I have to do the valve stem seals anyways. Just Fyi I updated the first post of the parts needed to complete the swap, that I am still missing. The snow ball effect is a real thing. :P https://cimg8.ibsrv.net/gimg/my350z....aa21627438.jpg https://cimg9.ibsrv.net/gimg/my350z....5fabc7c65a.jpg https://cimg1.ibsrv.net/gimg/my350z....1b19edf00e.jpg https://cimg3.ibsrv.net/gimg/my350z....de43b83373.jpg https://cimg6.ibsrv.net/gimg/my350z....1502e58324.jpg |
coming together - good stuff!
|
Just test fitting there's no head gasket installed. Thanks
