and thats a pretty looking engine bay, but I have absolutely no desire to mess with TT z32's. They are a nightmare to get around especially in the engine bay.

3 worst activities is doing a turbo replacement with the engine in place, Bolt on the back of the alternster thst nobody replaces. Passenger side stock downpipe removal.

I had to cut up a 10 mil wrench to do that last job.

My friend has a VH45de engine in his track focused 300zx with electric power steering if you need any help finding what works. He had a manual rack but sticky 275 tires on the track made it really tiring to drive.

I will defintely be reaching out for details regarding the PS setup.

I would never replace a turbo in the car, its self torture :D Easier to pull the motor.

That girdle built into the main caps is amazing.

The car is fantastic, dig the fab work.

The OEM configuration of the girdle/main caps is a limiting factor for the VG motor. I think people can safely make about 700hp before it gives way. I have no intentions of making that kind of power but there is an alternate solution provided by mazworx which converts the 2 bolt bottom end to a beefier 4 bolt bottom with billet hardware. Pretty cool piece of engineering.

Some progress today, not as much as I hoped but the bipolar weather wasn't exactly cooperating either.

First order of business was taking the rear bumper off the donor car. The bumper currently on the car is hideous and trash.


On that same note, the rear end is coming together. I picked up the spoiler of my choice, OEM 94+ wing. Not the most popular choice but I think with the end result it will look the part. I would love to get a diffuser out back, if i end up getting a lip for the 99 bumper I will probably do the diffuser for sure. Spoiler is just mocked. Also need to get a new 3rd brake light.


Firewall has been scuffed as well as the driver side of the engine bay. Plan is to give it another once over to make sure I get all the nooks and crannies

At the bodyshop watching my painter mixing the magic ingredients..


The connection is complete


and now I finally feel like I'm at the midway point of this build..! I actually sprayed it yesterday. NOTE: I did not use clear coat in the engine bay. Due to the heat it turns yellow. So this is just primer and basecoat. It wont have that shine and sparkle like the paint will on the rest of the car, but as mentioned again, im not one for pretty engine bays. As long as its clean and functional, im good with it.




After the paint dried over night, I went back today and began to put the engine bay back together. Spent my whole morning putting this thing back together. Man this shit adds up on the clock quick. I keep telling myself I'm done with cars and these builds but I keep doing this shit over and over again. fawwwk. I managed to finally remove the stickers on the radiator support and scuff it as well. It will get painted with the rest of the car. This is as good as she's gonna get for now. While I wait I will scuff down and clean up the coolant reservoir and catch cans and also flat black paint the plenum. Ordered a complete gasket kit, hoping i get it this week.

Payload arrived from z1 motorsports


had some time since im waiting. Did 2 things..reassembled the heads since they came back from the machine shop and also painted the VC's and plenum. Not looking for anything fancy under the hood..just want clean and functional as mentioned before.


After scuffing


End result-low key. Still ugly, maybe later down the line ill get a nice one



Wanted to inspect the oil pump..didn't like what I found. Its going in the trash. The cover is scored, I don't think that's normal. New OEM pump OTW.



Heads are back. Still waiting for the bottom end. I began reassembly immediately.





Heads are together for the most part. Cam gears and rear covers will be installed and tightened down to spec after they are bolted to the block


Here is my workspace. Not ideal by any means but glad I have a spot to do stuff. I don't think I've lost anything yet...but we'll find out when full blown reassembly begins lol

Among the shipment of parts was a complete engine gasket kit


Old gaskets that have been removed so far


Cleaning up the RTV on the oilpan


Getting there. Also cleaned up the oil pickup, oil filter housing. Installed new o-rings in both and cam seals inside both heads.

Yeah, I wouldn't be too happy about that oil pump either. Nice work! Intake looks much better with the coating.

Im almost wondering now if that non harmonic crank pulley had something to do with it. Only reason I cracked the pump open was because it was a low mileage oem pump.

Hmmm could be ratting the pump around a little more than it's supposed to! I think some people underestimate the importance of good balance.

Well I got the motor last week..its been a busy week. After getting delivery I had to order a few odds and ends so its not in the car and running yet but im pretty close.


Picking it up from the machine shop...


Loaded up..and en route to the shop






I wasted no time and immediately got to work..new oil pump and strainer installed


Water pipe Installed


Rear Main installed


Oil Pan is sealed. Bottom of the engine is complete.




I was slightly delayed because i had to buy new headstud washers. the ARP set isn't quite up to the task.



Heads are bolted down. ARP studs torqued down to 100ft/lbs with lube. Once I had the heads on, I threw the intake plenum on and the fuel injectors as well.



The exhaust valve covers dont use gaskets, straight silicone. I hope it doesn't leak



VTC solenoids installed


Starting to look like a motor again. Everything on the top of the motor is complete. Plenum, injectors, VTC, valve covers, etc...now the front of the engine is left.


Installed timing backing plates, torqued down cam gears, installed new timing belt pullies and tensioner
