e30 rb25 swap

[jute91]

Nice project, but im only worried about your welding :S out of gas?

[brandon5]

would the neo rb25det's work as well for an e30 or is that another wiring issue on itself? (Not a clue about nissan motors.)

Great project btw!

You could wire in a neo forsure, you dont see very many around though, and thanks man!

Biggest update today... IT RUNS!!

Got the motor in on its own mounts yesterday and decided to wire it up.







Everything fits pretty proper, in this pic i have the radiator where it should be, as well as a 16 inch pusher fan and a greddy intercooler.

I test fitted the lights the other day and the tubing should have enough room to squeeze under the highbeam.



Quick pic when i first got it in, if you dont have a removable rad support... do it.



And heres the reason ive been slow with the updates, lets just say body work is hard one handed.



My hand slipped into the flywheel when the gas bottle fell into it. 6 stitches and a broken finger later... im pissed lol. And yes thats a race mower with a 12 horse motor on it. Red snapper ftw!!



Heres the video of it firing up,

If that doesn't work lemme know and ill get s direct link.

If it sounds like it pings its because only the flywheel is on in this video, also there is no o2, no maf, no intake, stale fuel, and one of the injectors is broken. Not bad :)

Thanks for watching so far guys, stay tuned!

I've been chugging along with the build as best i can. Ended up staying at the shop all day try and finish up the shaved bay.

Keep in mind everyone, this is my first couple times welding. And today was my first time with the mig welder (which i love now).

Got the passenger side all tacked up, shaved the welds down after and im basically ready for filler.




Got a sheet welded on the drivers side but didn't get to finish the rest. Its taking forever stripping the sealer and grease off this thing.





After the welds are tacked a little more ill be using a panel adhesive to smooth the joints.



After that is all sanded down ill probably use a short strand fiber and end with a finishing glaze.

Also if you didn't notice i removed my rad support (drilled out the spot welds). I will be making brackets that will bolt on to the chasis and fender wall to hold everything in place.

Im still having alot of trouble figuring out what rad to use for sufficient cooling, and also how im going to mount it. So far the best option is to shave a bit off the inside square of the rad support and remove the bulge from the hood release. I should then be able to fit the rad inside of it. The stock bmw rad does fit (within mm's to the crank pulley) but i dont feel it will cool the rb, especially with a front mount.

Thanks for watching, i should have the bay ready for filler in the next day or 2.

im looking forward to seeing the end result!

The tranny brace isn't as low as it looks, but i am doing what you mentioned in that pic. Just gonna cut that section out and weld some plate in.

My goal is to have this at eurokracy, but im not sure if ill have wheels by then. May be rockin steelies on air lol Im also hoping to buy an accuair controller by then because manual management blows big time.

[mtlbloodshot]

Is she gonna be ready for Eurokracy?

[F34R]

Your car is also very low, you are bound to bottom out and catch on speed bumps. I would remove the brace and cut out this bit pictured below then box weld the bottom solid. If the other side hangs down I would do the same.

Build looks great though! Godspeed on the first firing of this new power plant.

Very small update, seeing as now its just a waiting game for parts to arrive.

Got these in the mail yesterday!



"Started" shaving the bay, Im basically cutting sheet metal to weld over the existing uglyness. Im sanding everything down and using zinc primer so it doesnt rot from the inside out.



Also realized why i hate old things again,



And just because i miss this bastard...

[brandon5]

Small update,

Tranny crossmember is done.







Finishing up a little idea i had for the motor mounts at the moment so i should have more pics tomorrow.

Get rid of the ceramic bladed turbo ASAP lol

i don't think any of those are still intact by this point; they all shit the bed the first time the original owners tried running a few pounds more than stock.

[brandon5]

Haha yea man! I always dreamed of a 2j but this is a lot cheaper.

As for the turbo, it came with a gt2540 Hks. Good for 20 psi and 400 hp.

Thanks guys!

shit!!! ive been dreaming about a RB25 e30 for years! is a DET model? so badass, keeping the 2.5L

[brandon5]

looking good man, check out my build for any ideas. i welded mount perches to the frame rails also, and i also ditched the booster, plated the firewall and moved the master cylinder over and mounted a remote booster on the passenger side under the dash....just another option for ya.

I'll have to check that out! Thanks man.

As for the mounts, yes they do look interesting lol. But so far they are feeling pretty strong. I'm not exactly done yet though. I'm adding some stuff to it hopefully tomorrow. The tranny mount should also be done tomorrow as well.

Also, I got my wiring harness back today and it looks awesome. The only thing he could hook up was the check engine light. I'll be wiring the cel to a light which will turn on if it's triggered. That way I can still read my code off the ecu.

I'm hoping to get some fuel lines and vacuum lines this week. I'd really like to see of this thing starts and idles right.

I'll try and get a video ad some more pics tomorrow or the next day.
