My E30M3 S14B23 -> S50B32 -> RB26DETT. We are alive!! p.28

[Mr. Horsepower]

Great work on this project! Very nice work and attention to detail. Is that an EFR Borg Warner?

Thanks! Yes, it is an EFR. T4 twin scroll

Ahh gotcha. I figured at least 2 were rocker covers but wasn't sure of the others. Looks like an excellent setup. I love seeing such a project where each detail is well thought out and done right.

You also just spurred some ideas in my head :D

Can't wait to see the motor fully assembled

I have done a lot of research during the last half year to come to this. So I want to do it properly. Glad you like it and notice the details!

Just feel free to ask if there is anything more unclear.

Thanks mate, means a lot!
The AN12 on top is one from each rockercover and the AN10 on top front is one from above oil level in oilpan and from the old return line that the rear stock turbo used. So good crankcase vent. The AN10 in bottom is just an optional returnline to the sump.

The blasted parts is just painted with black wrinkle paint like the S50 was.

Nice work on that catch can! What gets hooked up to all of those AN bosses on the top and side?

I hope you powdercoat all those pieces in the picture above white. It looks good like that!

Also I've been subbed to this thread for a long time now but never posted. Keep up the sick kickass work. I've been loving the frequent updates lately!

Ok, so, time for update again! As sad as it is, I'm moving to another place this weekend. And the car will continue to stay where it is for now. That leaves me with about 2.5 hour drive to get to it. So there will be less progress here from Saturday and on.

I just have to use the weekends to get shit done before the winter kicks in and it is getting to cold to do anything. So this is the reason why I have kicked in an extra gear these few weeks. Staying in the garage from 3pm to 11pm.

Getting more and more things done here, and I'm starting to see an end to this. I have engineered a lot of custom parts for this build, that is things I have never done. I have always done things that other people do, but this time it was my turn to invent the wheel.

I'm the type of person that want to help other people find information on the web. If you want to build a proper RB26 swapped E30, I want you to find the answer to all your questions here. But I assume most people toss the idea away once they see all the work it require.

What have I done since last time? I have build the intecooler pipe from turbo > Intercooler, cleaned the sandblasted parts for sand and dirt, finished the oil catch can, assembled the first half of the intake manifold and made the plug to the speedometer sensor on the gearbox.

So, let's start with the intercooler pipe. I'm actually not happy with how it turned out, but it will do the job for now.



To get this finish on the pipe I used steel wool.



For the gearbox I just made this really quick. Tapped the hole, put in Loctite and high temp RTV silicone for sealing.





The catch can is another story. I had no clue on how these was supposed to look inside, and no one could ever give me a proper answer to how I should build it eater. But I understood that the hot oil / vent needed to hit a flat surface before exiting the can. To get that effect I spot welded a plate inside the can, and there was also needed stainless steel wool as a "filter" for the steam or what I shall call it.

So I opened the can and spot welded the plate.





I then continued to seam weld the can



Stainless steel wool that I bought on the grocery store





Stuffed in the can



Aaaand DONE! About 5 working hours to make this can.









All the parts that is sandblasted and washed.



Assembly of the spacer between the throttle bodies and the head. I do not know what I should call this part. Carburettor maybe. On this part there is a vacuum rail and a water rail.



Scraped and cleaned the old silicone gasket



I use this RTV silicone for the job





Assembled





The NISMO thermostat was installed together with the thermostat housing.









Painted the bracket for the throttle and throttle linkage black



I just put some parts on the engine to see how it might look. I like this a lot!

Too freaking cool.

[Mr. Horsepower]

Awesome would love to see this thing in person. Sounds like a great road trip
I live in Stuttgart and I'm often down in the Alps. I Just drove Susten/Furka/Gotthard last week (amazing). Would be really cool to join you guys for an afternoon or something :p

Sweet. I do not see how that can be a problem, just for me to remember to contact you when the trip is happening :) We are aiming for 2016, but we both have our cars under the knife.

We will also drive the Susten/Furka/Gotthard route as well. We are also going to cruise the streets of Monte Carlo, and yes, that is going to be on tape :P Hopefully we will get people to lift their eyebrows.

Thanks, means a lot! Me and my cousin is actually planning a trip to the Alps with our cars next summer. Starting in Alessandria in Italy, and work our way from there. Monza, Monaco, Nice, Grimsel Pass, Susten pass, Stelvio, Hitlers eagles nest, münchen, stuttgart, hockenheim ring, nürburgring, spa and back home. About 3 weeks and 7000km with my E30M3 and his 86 Sierra Cosworth.

So, what have we done today? Yes, I have welded some more aluminium.
This time on that shitty expensive turbo.

Started off by removing the compressor housing



Then I masked it up with aluminium tape



Cut it of with a hacksaw





Drove over to my workplace and made it ready for welding



Spot welded





Work in progress



Done welding



Used this weld as a reference for how much heat I should work with. So this needed to be match portet a bit.



Ported and cleaned



I then sanded the pipes and finished off with some steel wool. Afer that I cleaned the hell out of it!



Final product





And I had to test it in the car before bedtime!





Also bolted up the oil cooler. Did not have more left of the clear bolts, so I had to use an anodized one. This bothers me, so I have to buy some more bolts so they can all be the same.

[Mr. Horsepower]

how much was the welder?

In freedom currency, about $1200. But I got a very very good discount.

[Mr. Horsepower]

I've only posted in this thread once or twice, but I do check back on your progress often. One of the coolest projects on r3v!
I liked the S50 the best, but everything else your doing to the car seems like top work and I love the fact you're actually driving the car hard, and bringing it to the ring etc. Let me know next time you go and ill bring my car too :up: haha

Thanks for the updates.

Did get some more things sorted. Have sand blasted the things that is going to be paintet, got hold of some parts for the exhaust, aluminium bits to weld on the turbo and gold heat foil.
