Complete Guide on How to Relocate PTU, Set TPS, Timing, and Base Idle On a 1990-1996 Nissan 300zx

[@jonathanbernabe9290]

Forums are great but these videos are really the saving grace. Im sure youve helped many not give up on this beautiful car.

[@ZBruhzchannel]

That was our plan! Thanks for the support!

[@NCTL05]

This will come in handy for real. I'm bringing one back to life now.

[@ZBruhzchannel]

Awesome!

[@justinhumphries8215]

Robbie is the man. I have just entered the “z-world” and have a lot to learn and y’all’s videos help out a lot. I’m stuck with mine on a security deterrent issue, well that’s what a local mechanic told me at least.

[@estebond008]

Truly enjoyed this video with such valuable information. You both are a good team. Keep it up!

[@ZBruhzchannel]

Thank you!

[@brianlabbie]

So glad I found this Channel. Someone just gave me a 92 and I don't know anything about these cars. You've been really helpful!

[@ZBruhzchannel]

Love it!!!

[@dgeez123z]

Id love to have my car with you guys for a week. Dealing with engine cont fuses blowing currently. Every connector is corroded. WAHHHH

[@igguka]

Just keep diagnosing!!

[@Mario-et3tp]

Amazing how to video thank you!

[@ZBruhzchannel]

Thanks for the support!!

[@joelybarvo5707]

Hell yeah your z motor is nice I like what u done with it and listening to your friend talk about working on the motor his knowledge about it is fucking awesome. I definitely paid attention tell him thank you 😎

[@hanskristianlundby4950]

thanks for showing me how i can set my car up. love your videos.

[@bignycatx]

Thanks guys, great vid. Better late than never but I'll check my timing tomorrow, been starting a bit slow in the mornings.

[@bignycatx]

Not sure if it's my age or what but I never noticed how high my idle is on my Z. I got my TPS to .44vdc but the idle is around 2000 rpm which means I'll have to get it down before checking the timing right? I've got it warmed up but I think I'll drive it around for a few miles and check again.

[@bignycatx]

Update: So I decided to re-seat the TSP gray connector (since that's the last thing I "adjusted") and the idle RPM dropped to just over 1000 (I knew it wasn't my age...lol). Checked the timing with Nissan DataScan app display screen and it showed 30 degrees. My Harbor Freight Cen-Tech timing light (with the dial setting on 15) shows it at 15 degrees and 30 degrees when the dial is set to zero. Which one is correct? Got the idle down around 750 RPMs but timing still has me a bit confused. He's running great, engine is smooth and not shaking or sound like it's struggling. Haven't done too much with Datascan app,,,just mainly use it to test injectors and view temp and battery readings. Any ideas what I'm missing? Thx.

[@bignycatx]

Figured it out, the DataScan display preference was set to add 15 degrees to the timing and that's why it showed 30 degrees. I found what my next project will be, saw a bit of oil around my #1 spark plug while setting up to check the timing. That'll be for another day after I watch your video on replacing the gaskets. Thanks again Bruhz

[@edmundsalvador2211]

I love this video Z-Bruhz and many thanks and likewise to Robie l learn a lot you shared by the way I'm from the Philippines I have the same Z32 92 model I'm following all the videos you shared so many thanks a lot bro more power to all of you out there .

[@sheldonmurray4016]

Great video man. I am Texas I wish I could bring my car for you to twike the little things

[@sheldonmurray4016]

Bought a volt meter today from Amazon am going to try it. I have some idle issues and hot start problems

[@dad_bod35]

Great video it helped so much I think i can finally get my z not running like crap anymore

[@ZBruhzchannel]

Ayyyye! Good luck with the build!

[@J9irizarry]

Appreciate your videos man very helpful my z,s been sitting, waiting on a how to like this one, very cool👍Do u use any special moter oil to prevent dry starts?

[@ZBruhzchannel]

I consistently use mobile 1, 10w40 in summer and 10w30 in winter

[@robertmaillet9882]

outstanding vid. I just finished pulling my TT engine and starting the rebuild. Qu: did i moss a video where you summarized how deep you went into the rebuild? Pop the heads or do a compression check before the pull? Saw the video on the lifters, just wondering if you changed the knock sensor and just how deep did you go? My drivers side turbo seized, so planning a full rebuild maybe down the main main bearings. Ideas?

[@ZBruhzchannel]

We did check the compression, but did not pull the heads. We also looked at the knock sensor and it looked in really good shape besides the debris from over the years lol. Compression checks are very simple to do, in one of our drifting videos we do a compression check on my drift car. Thank you for the support!

[@Dagrootx]

Great video!!

[@ZBruhzchannel]

@@Dagrootx thank you!

[@experiment86]

At the 20:36 mark, is that lifter tick I'm hearing?

[@ZBruhzchannel]

Probably because this was the first start up for about a month when the motor was out of the car

[@jancygonzalez6704]

Hey there I'm trying to get that spark plug connector piece as the shops around me cant due the timing because they don't have that adapter I can't seem to find any online do you know where you got yours everyone says I need the ignition lead but its been discontinued.

[@cdiego1318]

Does the crank pulley have a timing mark? I don't see a line on mine at all. Stock pulley

[@ZBruhzchannel]

It should have a little notch on it

[@alvankhan5094]

Hey nice work, how can i get you to help me with my z32 , im in florida

[@MoBLuBSiAb4LiFe]

I was wondering if i put new style injection but i dont use the adapter. Would that cause any issue?

[@ZBruhzchannel]

The injector caps will not hold the I sector in place. Old style is a round head, new style is a square head, and thr wire harness connectors also will not match up unfortunately

[@phatridesgarage3760]

Great Video Guys, I learned alot, great explainations

[@DG-lf3kw]

Very enjoyable, another great video!

[@ZBruhzchannel]

Thank you 🤙

[@nnand25]

Hey Im a Z owner too. I have a 92 300zx Twin Turbo. Theres a guy out here and he makes z32 parts from scratch and puts together his kits. His company name is Polar Engineering. He makes the PTU delte with GTR35 coil pack and its a simple plug and play. Im gonna order mine in some upcoming weeks. You should look into it. Its better for Idle and you can put bigger spark plugs in there. Look into man! Hope you Read This! yeeeeeeeeeeee!

[@ZBruhzchannel]

Thank you for the info! I will look into it for sure!

[@taipane-biensur7607]

Robby/Jeremy - Where did you get the Spark Plug wire Robby used in rigging up the contraption with that ignition coil. Been trying to find one and can't seem to locate anything similar. Kindly advise.

[@ZBruhzchannel]

All it is is a oem coil pack from a z32 with a spark plug wire from advanced/auto zone. No specific on just any kind of spark plug wire.

[@ZBruhzchannel]

He cut off the rubber from the coil pack and attached the wire and then used electrical tape to keep it strong. I hope this helps!

[@taipane-biensur7607]

Ah hah.. gotcha. I will give it a shot. I ordered my spark plug wire from advanced too. Will try it out when it comes in. Thanks so much Jeremy. Hope you guys are all keeping well.

[@chefchutardo5215]

Great video ! Gonna use this to set my timing. I didnt put the lower timing cover since car wont be going on the road for a while (got many other issues to solve before inspection). So i guess i have no choice but to put that lower cover back since timing marks are on the cover 😕

[@ZBruhzchannel]

Yep and make sure you use white polish to make it even easier to see!

[@SuperZitkus]

Ill be doing this tomorrow!!!

[@ZBruhzchannel]

🙌🙌

[@Paulcubb]

Help! I'm new to the timing procedure on a 300zx.I get it that timing is adjusted with a timing light,but what are you adjusting on the right side of the motor to move the timing mark.I see a place on the right side and I loosened the 3 screws and tried to rotate it but I can't budget it. Thanks.

[@ZBruhzchannel]

That is you cas sensor. This either advances or decreases your timing. Alot of people have issues with moving these due to corrosion. Best bet I have learned is use a tiny amount of wd-40 around the crevice where the two pieces meet. Do not use too much just some drops around the entire piece. Let it sit for 5 mins then grab a rubber mallet and carefully tap around the edges. You may need to use some force but once it's free you will be able to adjust.

[@Paulcubb]

Very informative , good work blokes

Very informative and clear!

[@kylemcnamara1318]

Great video. Is the TT motor timing set to 15 degrees too?

[@ZBruhzchannel]

This depends on what yo want your AFR's are and what your tune wants. I would refer to twinturbo .net

Stock is 15. Start there.

[@937wigger]

is this the same one you relocated the relay box to the front bumper area? If so, what made you move it back? Thanks!

[@ZBruhzchannel]

No this car i did not relocate the fuse box. The drift car is still relocated

[@keithyoung7381]

Very informative. Thanks

[@lukefreshour5349]

If I just sync up my throttle body’s, do I have to adjust anything else?

[@ZBruhzchannel]

You may need to adjust tps

[@ericfigueroa1134]

Did you calibrate the throttle bodies to make sure that when they close all the way you see the tiny vacuum port at the bottom of the throttle?

[@ZBruhzchannel]

Yes sir!

[@infamoussgarage]

great video, very helpful!!

[@937wigger]

Did you delete your air regulator? i know you still have the IACV, just curious if youre still running an air regulator, and if not, have you had any issues with cold starts? Thanks fam.

[@ZBruhzchannel]

I did delete my air regulator, I have had no issues after deleting it, it is used for cold starts. I let my car sit for 5 mins to get to operating temp and drive it.

[@937wigger]

Z-Bruhz that’s what I was thinking. I deleted mine and it solves my 1500rpm idle (no matter how warm the engine was). The AR must have been stuck open. Thanks dude! Keep doin your thing!

Check tps, timing, clean maf, ohm injectors, check Vitale at battery before car start and after!

It only stays running if I’m giving it throttle. Any ideas

Ay bro do a coolant change and oil change video.. I’m sorta struggling I just wanna make sure my engine is still worth saving even at 260k

Good stuff!

[@Commentthat]

I have a 94 and the timing gun I have moves the timing. I watched this video because I didn't have the tool. I took it to the shop and they put my timing way off. It was like at 22. I'm gonna set it at 15 tomorrow. Also going to check my intake valves are opening at the same time.

[@ZBruhzchannel]

Sounds like a great plan, 22 is way too advanced

[@Commentthat]

@@ZBruhzchannel it was 22 above 15 . My whole car was shaking. I fixed it but I will never go to that so again. . Learned it right here on this channel. Now I just need convertible frame bars. Very hard to find.

[@zackaryrients1863]

What does PTU stand for?

[@ZBruhzchannel]

Power transfer unit

[@zackaryrients1863]

@@ZBruhzchannel Thank you. BTW.. utilizing your videos I pulled my first VG30DE out of a 90'. My boss was highly Impressed. Seeing that I just transferred jobs and I am (or was) on a "probationary" status this went a long ways with him. I'm not a new Auto Tech.. 15yrs and two of my own shops... But I give it to you guys. These motor R&Rs are DIFFICULT! ALSO I NEED TO SWAP THE CAS To the new motor. Can't find any info on this part install. Any advise is appreciated. Cheers!

[@ZBruhzchannel]

@Zackary Rients thank you for the kind words! As for the CAS there are 2 types phase 1 and phase 2. If the motor is out of a 89-92 it will be a phase one CAS. The phase one engine harness will only work with a phase one CAS unless you swap the connector on the harness.. you can get a different connector on Z1 motorsports if needed.

[@infamoussgarage]

Yo anyway I can PM you I can’t get my TPS to read any volts. I followed the video 100%

[@ZBruhzchannel]

Sure [e-mail], but if it isn't reading anything it may be dead. They are very temperamental and die all the time if they are dropped or messed with in the slightest way

[@JoeLambert2711]

Why do you disconnect IACV yellow plug?

[@joeblow4795]

To override the ECU - you want base timing. The ECU will constantly change the timing +/- 2 degrees depending on conditions.

this is legittt would this be the same for a 92 tt

The process would be the same, but it may have different specific numbers that you would need to reach. I would do some research on twinturbo.net

[@tyranidoverlord]

Can I borrow yur friend lol 😆

[@zackaryrients1863]

Hey y'all. How many hours of Labor do y'all think, ball parked to replace the motor and swap some parts like the exhaust manifolds, new water pump, egr valve, motor mounts and motor brackets etc. Fill the radiator up and bleed, new oil filter plugs etc? All data says 19.6hrs. I call bullshit. 1991 300ZX N/A Z32. Couple other things, the dipstick is on the opposite side, heater hoses are different, few vacuum lines are different. The motor must be a different year or something! The dip stick in the replacement engine W/ 50k on the motor. Supposedly. Well said dip stick... Not the tube, is 100% caught up in something? Guess I'll have to pull the pan as well. F& CK!..
