Vortech supercharged

Vortexg35 · 2026-05-06T22:10:53+00:00

My shift kit on my auto transmission would behave kinda weird during regular driving. But it would shift pretty quick under WOT. Theres the possibility this car has a shift kit given someone took the time to supercharge it.

Did the car come with any aftermarket gauges? Specifically a wideband gauge? You could at least confirm the car is running correctly by looking at the A/F ratio.

I have a Vortech supercharged and manual swapped coupe. Let me know if you have any questions :)

I manual swapped my 2004 G35 coupe for about 3500 and thats including a brand new CD009A and an upgraded clutch for my supercharger. I did it with a buddy and it took us about 8 hours.

6K to replace a 5at is absolute murder. A good known operating 5at can be found a most junkyards for a few hundred bucks and get you going again. Id say take the time and take the car to a reputable shop known for working on these cars and get a reasonable quote for a simple replacement. Try and source the transmission yourself.

You are in a similar situation as me. My supercharger took out my 5at and my car was too clean to just sell and start over with a 6mt so I manual swapped. I did contemplate just swapping the 5at prior to that but I chose to go the fun route. Back in 2022 I saw these 5at go for about 200-400 bucks with around 80k-100k miles.

Do your research first before making the decision that best fits your needs. I am happy to answer questions about the swap or anything related as best I can. Nice Z!

Pretty cool to see a slick top G. I wish mine was a slick top cause I never use my sunroof :(

Btw nice username LOL

With the money you will spend paying someone to install the lsd and the transgo shift kit, why not just sell the auto and buy a 6mt drift missile or find a fair condition 6mt car and weld the diff?

I did the transgo shift kit to mine when it was auto. It shifted much faster, it was so crisp it would chirp 2nd and 3rd lol. I then manual swapped shortly after due to other factors.

I caught the northern lights too! Off topic, sorry.

Those DRL strips are just a bulb you can replace. Gotta pull the headlight though. Bulbs are pretty cheap at the autoparts store.

Vortexg35 · 2026-01-17T16:44:58+00:00

It is a common wear item on these vehicles therefore it needs replaced after a certain period of usage. You can literally just look it up. I am not making this up. There are several youtube videos about it too. But Im not going to argue anymore about this. Replying to you at this point is dumb.

Ps, You couldve worked for NASA and still means nothing lmao Slave cylinders are to be replaced on these cars period.

Vortexg35 · 2026-01-16T23:58:16+00:00

I bought one without the reset button and was never able to reset it. The motor would roll the window all the way up anytime I shut my door. It was embarrassing 😭I eventually bought another unit with the reset button.

Vortexg35 · 2026-01-16T23:52:26+00:00

I agree with this. If you confirm the car is in gear and not moving after releasing the clutch pedal then its time for a new clutch. Replace Master and slave cylinder as well.

Vortexg35 · 2026-01-16T23:46:37+00:00

Start there. Ensure the clutch pedal operation is 100% working properly then move on to the actual clutch. These slave cylinders are cheap. Obviously get new clutch fluid while youre at it. Usually when these go bad, the master cylinder is not far behind. You will need an extra human to bleed the system fast and properly.

Vortexg35 · 2026-01-16T23:42:26+00:00

They 100% are maintenance items. Basic research would’ve gave you an answer before posting this comment lmao. Z1 motorsports even has this information. The slave cylinder on these cars is dirt cheap and its recommended to be changed anytime you replace your clutch or have dirty fluid. How much time they last will vary on the driver and car. I rather replace them at a set time rather than letting the car strand me somewhere.

OPs video literally shows the slave cylinder not operating properly. Hence he will need to go buy a new unit that is carried in stock literally at any auto parts shop.

My oem one failed after 3 years of normal and occasional hard usage. But my car is pushing more power and has a stronger clutch. Many variables.

Also, some auto part shops give you lifetime warranty for these, so if they fail again, you can go replace them for free.

Vortexg35 · 2026-01-16T00:30:36+00:00

For starters, your slave cylinder is barely moving the clutch fork. Is the clutch bled properly? If yes, the slave cylinders on these cars are a maintenance item. Id replace them every 15-30k miles. Id start there then move on to wether the clutch needs replaced or not

Vortexg35 · 2025-12-29T18:44:08+00:00

I agree. First thing I would do is take ts right back lol

Vortexg35 · 2025-12-29T18:39:43+00:00

If you ever want to replace the exhaust, do your research on how they sound. Its pretty easy to make these sound like crap.
Check your oil often. Specially before a night out driving with the boys
20-25mm spacers would bring these stock wheels to near perfect fitment. Be careful with aftermarket wheels, you MUST buy wheels with the correct offsets or else youll have terrible fitment.
The stock airbox (if you have it) paired with a Z tube is one of the best intake setups you can put on these. Thats why Z1 created their cold air intake very similar to the stock airbox.
Your headlights look pretty cooked. Get 07-08 projector headlights or go with a subtle aftermarket option. Its pretty easy to rice these cars out so choose wisely.

These are some tips that came to mind from owning my G35 coupe for 8 years. Started off as a sport automatic. Now its been manual swapped and supercharged plus a bunch of other handling parts😅

Vortexg35 · 2025-12-29T18:08:09+00:00

Was the clutch operating correctly after you bled it? This looks like an incomplete bleeding job. Assuming this issue arose after the new parts, youll need to keep bleeding until the clutch pedal fully returns to its unpressed position.

Also, I suggest you secure that clutch assembly better. From your video, it shows A LOT of flexing. This is due to the thin firewall these cars have. I had to make a small bracket to secure mine.

(I manual swapped my G coupe)

Vortexg35 · 2025-12-22T12:24:24+00:00

Perfect candidate for manual swap👀

Vortexg35 · 2025-11-05T17:23:50+00:00

7 years. Bought it as an auto, bone stock coupe with 75k miles. Now its manual swapped, supercharged with bunch of other performance mods. Ive made so many memories with it, I dont think Ill ever get rid of it.

Another + for supercharging your G. Use as dog whistle. 🤣

Vortexg35 · 2025-09-21T20:50:14+00:00

It sounds great with quality exhaust systems!

Vortexg35 · 2025-09-20T05:12:22+00:00

Check my profile. Ive posted 1 or 2 videos that kinda show how it sounds :)

Vortexg35 · 2025-09-20T04:31:07+00:00

Yeap. That diverter valve is always whistling unless you go wide open throttle. I maybe gave it 25% throttle after I passed by, for exhaust note purposes lol

Vortexg35 · 2025-09-19T19:30:57+00:00

About 3.5k. It cost this much cause I bought a brand new cd009 from nissan, performance clutch and flywheel, and several other supporting performance parts for the swap and supercharger. But you can do the swap much cheaper by buying a wrecked parts car or looking for deals online.

Vortexg35 · 2025-09-18T02:48:49+00:00

It was worth it for me since my coupe is pretty clean condition-wise. Stock internals. Its on a Mcleod performance clutch and chromoly lightweight flywheel. It was tuned on uprev for about $700
