Thought i’d post a little update. Some more progress is supposed to go down this weekend. Like take the rear diff out to be welded (by someone on here, havent talked to anyone yet) Get the headers welded, school has been holding me back from getting this done. And a bunch of other misc work.

So i have definitely made some progress lately.
The shifter is finally figured out. Ended up cutting open the shifter hole and welding in a piece of steel, then welding the old 300zx shifter mounting to the bar. She is all lined up perfectly now. Can hit 1st through reverse smoothly now.
I also ran the clutch line today and bled it. The 6-puck RPS clutch feels NICE and is aching to be broken in.
Also had to re-drill a new hole in the brake pedal to accommodate for the relocation of the brake booster. So i did that and hooked that up. Now i can stop.
The headers are actually semi-complete now. All of the runners come together. Just need to take em apart and hand em over to my buddy to get welded up. Then it’s collector and finish the rest of the exhaust time.
This is the muffler i think i’m going to get. It’s a Dynomax Ultra-Flo X Muffler…
Let me know what you guys think.
So today Carl and i hammered out most of the drivers side exhaust. It looks much better than the other side.. i give credit to the stationary cutter i’m borrowing, it’s so much easier to cut a flat edge and angle’s.
We had to redo the whole thing because the one i made last year was too close to the steering column. The new header clears it with much more room. Here are some of the pictures.
The header was on the engine outside the car for most of the fab work. After we made sure it would clear everything, we just hugged each runner to the other runners and made sure we could get the collector on.
The fourth runner will be made later this weekend hopefully. Then finish the collector on the passenger side and the headers are done. Then it’s smooth sailing on the rest of the exhaust work.
Once again… copied from a previous post..
Ok, so the project is back in action everyone. I’ve made a little bit of progress so far. But it’s slow going. Hopefully things will start to move along pretty soon.
Anyways, i just completed fabricating the alternator mount. I’m using a 240sx alternator as the q45 one is way too big to fit in the bay. I would have to notch the frame rail. The water pump and alternator will be run on one belt and the a/c tensioner will be flipped upside down to tension it. I’ll show a pic of that later if i remember. Yeah i know, the welds are sloppy, they are just tac welds i did with my friends little 90 until i can go to my girlfriends house where they have a full size welder and finish them up.
Here’s as far as i got last year on making the headers. I realize they are NOT equal length. I plan to re-do them eventually when i have more time. As of right now i’m just planning to get the car running.
Here is a picture of the passenger side header just sitting on the head.
And here’s what i’ve got to work with. The mock-up engine is in the car without the tranny so it will be easier to finish making the exhaust. The tranny is huge..
***Alright, so here’s the beginning of all the madness. Since i’ve got all this tuff on a couple forums i just copied it all to here. It’s MUCH easier than re typing it all… Some of the stuff took place in 2005 but the majority of it in 2007. Enjoy.***
Ok, so this thread is basically explaining what I have been working on during the past three summers.
The original plan for the car was to do the incredibly popular SR swap. I ordered a front clip from a business after talking with them a lot and they gained my trust. It was roughly $2500 out of my pocket. Unfortunately the businesses supplier flaked and didn’t ship the clips. I have received all but about $570 back from this business. It took nearly a year though. This basically destroyed my plans for the summer and I was stuck. Instead of selling it I kept it and looked at other options.
I was in a junk yard one day and happened to see an infiniti j30 which has the vg30 engine in it. I was going to do this swap but then wondered what engine was in the q45. I found out it was a 4.5 liter quad cam v8 called the vh45de which put out 310hp and 330tq at the crank with 10.2:1. compression and a 7000 rpm redline. It also has VVT. It is an all aluminum block that I think weighs somewhere around 480 pounds. Yes it’s heavier but it won’t be that much different from an RB swap. Only the early models made this power because of a change made to increase emissions. But anyways I was sold. I did some research and found that someone had put the later version (a smaller 4.1 liter vh41de) in an s13 but couldn’t find one with a vh45de.
One person did this swap into an s14. Everything is stock except for the exhaust and intake. He is making 275hp at the wheels.
^ So I ran across this 1990 q45 with 256xxx miles on it for 900 bucks. Picked it up for 800.
These engines are way overbuilt and known to last extremely long. The only thing that needed to be replaced on these early models were the timing chain guides because they were plastic and broke from becoming brittle. Unfortunately this engine did not have the guides replaced and it broke and became lodged in the oil pickup tube. The heads looked burnt and I became pissed.
^ I stripped this thing of ALL of its wiring and anything I thought I might need. Then had someone come literally drag it up onto a flatbed and haul it away, which was really cool to see. (I kept the wheels so that’s why it they dragged it up)
^ Here is the engine out of the car. Unfortunately this engine did not have the guides replaced and they broke and became lodged in the oil pickup tube. The heads looked burnt and I became pissed. So I could get the heads cleaned for free but the valve seals would have to be replaced
Anyways my friend happened to find another q45 in a junk yard that only had 150xxx miles on it while looking for other parts. I checked it out and they said they would sell me the block, heads, intake mani… everything short of the alternator and a/c compressor for 150 bucks! I didn’t have to think twice about this because that was way less what it would cost me to rebuild the other engine. Plus now I had extra parts!
Now everything you see past this point has taken place during summer of 2007. Progress explosion!
^ This made my day when I pulled the upper chain guide cover and found that the guides had been replaced. See the metal backing? Thats good! (saves me about 370 bucks!) Also look at the front of the head! Its CLEAN! Very clean!
^ I was basically the happiest person on earth when I pulled the valve cover off on one of the heads. If a head looks this clean after 150xxx miles you know the previous owners did oil changes religiously, it also had a mobil oil filter which gave me an idea it was in good condition… and I thank them for that. Whoever that is…
^ Here is the custom adapter plate I ordered about a year and a half ago. Maybe longer. It was a group buy I happened to come across when I was researching the swap. Only 5 were made and it was made in the UK. ($750) The reason for this is that no manual transmission bolts up to this engine.
^ Here are the engine and tranny mounts I made out of quarter inch steel. My friends dad welded them up for free. For the tranny mount I used the stock ka auto tranny and welded two 1/4” pieces of steel because it sat back a little bit. Some people actually cut the mount and re-welded it. Which I found un-necessary. The stock z32 rubber mount was used for the tranny bushing/mount/whatever you want to call it. And hockey pucks are used for the engine bushing/insulating/whatever you want to call it.
^ Me fabricating the headers out of mandrel bent tubing. (Thanks to friends for letting me borrow the welder and helping me fabricate these) These weren’t finished in time so that’s why it had to go to storage again. I purchased all of my tubing through “Headers by ED” he also helped me figure out the correct size tubing for the exhaust system.
^ On the bottom of the engine there are two black braces for the bottom of the tranny. At first I wasn’t going to use them because I didn’t think it would allow for clearance over the steering rack. But it clears.
^ Here is a picture of the distance between the brake booster and the drivers side valve cover. This was after we re-drilled holes and moved it up and to the right. This is also a brake booster from a Nissan Sentra, s it is much smaller than my stock s13 auto booster. I have q45 brakes to make up for the loss in braking power.
I’m not too concerned about how close it is because the engine is mounted pretty solid in there.
^ Picture of shifter position. It’s almost perfect, sits a little to the left. There was a rod originally on it that I cut off and just re-welded the bracket from the other end. You can see the welds where I did this.
^ My hood won’t close anymore.
And those wires’ hanging over is the custom harness I made. It’s there just for testing. Making sure it works and all. I got as far as cranking it over. I didn’t have fuel hooked up so it never fired. And the exhaust never got completed, I ran out of time.
^ Picture right before we towed it to storage just this past summer. Its sooo close!
And that’s my dad helping me hook it up to the trailer. Many thanks to him for letting me use the garage all these summers and bearing with the project.
One main frustration of this project was figuring out the correct wiring. I think I had to wire up a total of 10 wires. All necessities.
I still have to have a custom driveshaft made. I called around and can get a basic 1 piece steel drive shaft made for under 100 bucks.
And I also still have to run the clutch lines and make a custom bracket for an alternator.
Will be using a 240sx alternator because of fitment issues, would have to notch the frame otherwise. Another person used it with this engine and works fine.
If you have questions please feel free to ask. This is an enormous project and I’m sure I haven’t covered everything in this single post.
I also have MANY more pictures i could post up if someone wants a different angle.
So this is my first post on here. I used to think blog’s were kind of dumb… but over the years I’ve been looking for a good way to document what I’ve been doing with this car so i can keep track of it’s progress. I used to think a ‘build thread’ was a good idea but people on forums don’t want or need to read every little thought or detail you’ve done or thought about.
So after reading a few people’s blogs i figured this would be the best way for me to keep track of anything. Those of you that end up finding this blog and know of my build threads (under the name of CrazyTrance) on D-Town or NICO might say it looks much the same. Don’t worry i’ll add new stuff soon enough, just in the process of getting everything laid out so bear with me.
