ooooohh shiny :)

[Mr. Horsepower]

Parts parts parts parts :) Have not done any more work on the car, just got some more parts!

Mishimoto intercooler



Competition Clutch stage 4



Greddy timing belt and Nissan tensioner and pulley



ATI Superdamper 1000hp rating



ACL Race rod- and main bearings. Nippon pistonrings



Some ARP suff. Head studs, rod bolts, flywheel bolts, pressureplate bolts and exhaust header bolts. The main studs was missing. Grrrr



And that pretty much leaves us with this, plus the used stuff that is laying in the garage :)

[Mr. Horsepower]

Have been working a bit on the car the last days.

Did get the intercooler mounted, and did mock up some other bits and figured out how to do things.

Made some room for the cooler in the front bumper here. Just used the grinder to shave off some plastic.



Had to shave off one of the points that holds the tow hook cover in place, when the tow hook is used.



Made some brackets for the intercooler, and a new lower mount for the radiator. The intercooler brackets is not finished on this picture.



And that leaves us with this. Always wanted a intercooler behind this front.



Bought a new 13 row MOCAL oil cooler. The HKS one did not fit where I wanted it.



And that MOCAL cooler will sit right on top of the intercooler.



New coils did also arrive. These are named Benchmark, and have gotten a lot of good reviews. They will do for my power output anyway.

What size intercooler is that? Fits well

[Mr. Horsepower]

What size intercooler is that? Fits well

In freedom units it is overall size 24.5" x 11.75" x 3"
Core size is 17.5" x 11.75" x 3"

HAHA :rofl:

Looks like you're making great progress!

[Mr. Horsepower]

Well well. Some more parts have arrived. I love Ebay <3

I have been back and forth about how I'm going to build my engine mounts. My first idea was to use the GTR rubber, but placing them in the crossmember did not work. They have a steel plate surrounding the rubber, and them being wide it was hitting the chassis. From my experience that will result in a lot of noise.
After thinking and searching the internet I found a shop in Poland named Silver Project that had these solid looking (and fair priced) polyurethane mounts.
Since I have modded my crossmember to fit E36M3 mounts, I went for them for this build as well.

In 2014 I had Vibra Technics competition mounts for E36M3, and when I pulled them out the bolt was bend and the rubber had given up. And that was after ONE track day. They cost a lot of money as well, so they was not an option.

The Silver Project mounts is made of steel and have two round polyurethane bushings. They are stiff as hell, and I just hope there will be not to much noise in the coupe. But after all, they are E36M3, so I can swap them for what ever E36M3 mounts I want.

Gearbox mount is also bought from the same shop. That one is for the R33 GTS gearbox, and have not arrived yet.

So I have build my own mounts and (finally) placed the engine in the car. I have started to work on the new shifter as well, but I have no photos of that.

A universal throttle cable have arrived, as well as a brake light switch for the Garagistic pedal box bracket. Mine was square, and that one needed a round.

AAAAND, today, the turbo arrived!!! :D

Anyway, here are some photos:

Silver Project E36M3 engine mounts





Throttle cable kit:



Brake light switch:



Also have been making some brackets here and there. And I like when things is looking like they are bought. So they are being sanded and polished to mirror finish. This there is for the oil cooler on top for the intercooler.



My engine mounts. Made out of steel, and just tossed some paint on them.















And the turbo. Borg Warner 7064 EFR T4 Twin Scroll .92 AR

and to think that id just be happy with a s50b32

[Mr. Horsepower]

Got some more things done today, and I got four packages in the mail :D What turned up today was Silver Project gearbox mount, used Opel Zafira electrical powersteering pump, AN-8 (9.5mm) aluminium tube rolls and a lot of aluminium tubes and silicone hoses for the intercooler.

I know I'm not good at posting pictures of things while it is in progress, and that is simply because I'm working with full focus and dedication. So it does not come to my mind before the product is done.

So. The other RB25/26 E30 build I have seen have had the shifter come up in the center of the stock shifter hole. If the engine had been in that position, which is about 2 3⁄4" more forward, the car would gain even more load on the front axle. So for me it was not an option. That lead to some cutting and some modding of the shifter itself.

I simply cut out to make room for the mechanism, and then I build my own shifter. Parts that is used is the Nissan lower part, a regular bolt and the top of a E39M5 shifter. Meaning I can camoflage the whole Nissan shifter. So I can still use my Sport Evolution gear knob, and the ///M stitched suede boot. Will need to get a custom shift pattern top for the knob, since it have reverse on down right.
The shifter also feels a bit sloppy, so I might get a Ebay short shifter kit and remodel it a bit.

Here is how it turned out:





The new gearbox mount:



Opel Zafira powersteering pump:



A box of pipes and hoses. Will lay out on floor and take picture later, was not time for that today.



Just stared to play a bit with the tubes, to have a quick look. They will be painted matte black after welding.



Looks like it will fit. Cant wait to start on the downpipe....nightmare.



Quick overview



And the two rolls of aluminium tubing for the fuel feed and return lines.

[Mr. Horsepower]

Have done a bit the last week, not much though. In the middle of buying a new appartment and stuff like that. So, have to make that the priority.

The engine is delivered to the engine builder, and just waiting for him to do his magic. Other than that there have arrived some parts.

Nismo thermostat:



AN12 rocker cover breathers:



Oil line and water line with fittings for the turbo



The Wilwood pedals and masters



Custom driveshaft

[AdOz]

Wow! Il be keeping an eye on this one!!! Good work

[Mr. Horsepower]

Low interest in this project

Okay. Have done a bit since last time. The 6Boost manifold did arrive at last, and this is high quality craftsmanship.







The oilpan is done. Extended the sump and made a kind of baffle inside. I have not welded aluminium before working on this oilpan. But I'm getting to it after all these hours on this oilpan.

First I started cutting off the sides and made the baffle plates.







Then it was to box it in.









Went on with 4pcs AN10. There is some spare, but I want to have some extra in case there will be different catch can solutions in the future.



And the final result after hours of building







I have also buildt the pressure pipe for the intake side.







Then I buildt my catch can. This is just fixed together and tested to fit the car. It needs to be some baffles and filters inside. But the design is done.

Started off with basic aluminium plates. Drilled the holes for the weld bungs



Spot welded





For the breather filters I went with regular 25mm aluminium tubing



Drilled holes and spot welded





Then it was time to spot weld it together. Getting everything in 90 degree angle is important. So I took my time with this.









I then took the box to test in the car, and I had to modify it a bit in one corner. So I ended up with this as the final result







And this will sit in the car where the stock coolant expansion tank is placed in the M3.





Another story is the engine. I picked it up yesterday from the engine builder and he has put down a lot of high quality man hours.

Since the RB26 suffers from a crap oil system, there is some work that can be done to make it better. One of those things is drill the oil return galleries bigger to match the head gasket. The main problem of the RB26's oil system is that when you push it hard it fills the head with oil. That results in a dry sump, the type of dry sump you don't want. And we all know what will happen then...

So, I got some photos from the builder on the job he did with my block and head. He will send me photos for the rest of the build later.

First he pressure tested and honed the block. Then he put it in the jig to drill the return holes.



The holes for the return galleries can be seen here





Here with the Cometic MLS head gasket





He then started drilling out the galleries









Quick look at the underside of the holes



The same was done to the head



Smoothing the edges to make the oil enter easier.





He then decked the block and mounted the 1.2mm oil restrictor.





Smoothing the edges





And the final result







The oil pump did also get some work done. This is a JUN oil pump, which is supposed to be high quality products. This is not always the fact. Lets take a closer look.







First thing that showed up was this foam piece.....





The gears was dry. No type of grease or lube on them. That would tear a lot when you are starting the engine for the first time.



Here you can see sharp edges and no smooth machining. This is not good for oil flow.









The same ports after some porting an polishing









Cleaned and ready for assembly



He put on some special grease on the gears



Checked the pressure preload on the spring



Loctite on the bolts



Done and done





As I mentioned I picked up the engine yesterday. I was home late, so I only took some quick photos.

Thank you for taking your time, showing us all your work.
Your M3 is going to be even more awesome, looking forward to see the final result with the new engine.
