My RB Project, going all in!
49 Attachment(s)
Was going to wait till we actually start building the engine but I ran out of patience, waiting on parts to arrive can be such a bitch!
So to keep it short, got bored of the VQ and its slush box, the engine's compression is too high to boost reliably without selling a kidney, and on top of all, the VVEL will forever be a bottle neck on this engine. Solution: RB swap :D Picked up an RB30E bottom end, cast iron block, long stroke, with enough torque to move the G around, mated to an RB26 twin cam head (lowers the compression to 8.4:1) and an RB25 gearbox since I will be keeping her a RWD. To this point, we got the following: RB26 head & RB30 block, waiting on head bolts, gaskets and cam belts Attachment 159437 RB25 Pull Type gearbox https://i451.photobucket.com/albums/...1121-00329.jpg A snail crawling around in my living room... Attachment 159438 RB26 Intake Manifold Attachment 159439 RB26 Exhaust Manifold Attachment 159440 VH45DE 90mm throttle body, mechanical throttle FTW! Attachment 159441 Update: 26-11-2012 Gasket kit, head bolts and tensioner kit have arrived and have been dropped off at the shop. Aiming to start stripping down the G on Saturday! Attachment 159442 The manifolds were just held against the head to measure clearances from wheel well, we may have to re-route the wastegate pipe. Attachment 159443 Intake side should not be a problem Attachment 159444 Update 28-11-2012: The head has been sent for porting, polishing and final prep work before getting fitted back in. The block is getting painted and drilled for the tensioner. In the meantime, this showed up at work today: Attachment 159445 3.5" intercooler and an Oil Catch Can. Update 03-12-2012: Engine and head are finally ready! Car has been dropped off today to begin surgery. Here's what all the head covers and pulleys look like so far :D Attachment 159446 Update 06-12-2012 Engine test fitting began and it is looking great so far! Attachment 159447 Attachment 159448 The intake manifold inlet will he have to be slightly modified to fit the throttle body due to limited space Attachment 159449 The turbo side however is a tight fit Attachment 159450 Attachment 159451 The wastegate pipe is a little too close for comfort too, may have to be modified as well. No so sure yet. It is looking great so far! Update 08-12-2012: The following pictures will not be easy for the weak-hearted :p . . . . . . . . . . . . . Doesn't that shifter look like it just belongs there? :) Attachment 159452 Attachment 159453 Well it wasn't work of magic though, the transmission will have to be pushed around 26mm away from the engine to get the shifter position where it belongs. A spacer will be made to sit between the engine and transmission housing. The flywheel will also have to be pushed by that same amount. You can see the tiny spacers currently being tested. Attachment 159454 Attachment 159455 Since the transmission's cross member will be slightly relocated, some new holes had to be made Attachment 159456 The crank case also wanted a share of the action, it wouldn't fit properly around the engine's cross member so it had to be modified. The mechanic suggested he will be test fitting an RB25 crank case as it may be easier to work with, let's see how that goes. Attachment 159457 Attachment 159458 Transmission alignment in progress Attachment 159459 http://i451.photobucket.com/albums/q...p/DSCN0510.jpg The wastegate pipe continues to pester around, this time around the steering column. The mechanic says the engine is not 100% aligned yet, once done it will move further away from the steering column. Attachment 159460 Update 10-12-2012: Great news! The shop is done with the engine and transmission alignment and I couldn't be happier. The shifter now sits 100% OEM and the best part, I won't even have to modify my center console for it. Shifter in Neutral Attachment 159461 Shifter in Third http://i451.photobucket.com/albums/q...1210-00362.jpg Shifter in Reverse! Look at that clearance! Attachment 159462 Shifter in Fourth Attachment 159463 Engine mounts have been spot welded today, everything is looking perfect. Tomorrow they'll get welded and finished to look 100% OEM Attachment 159464 Attachment 159465 The Transmission spacer is also ready, 26mm thickness Attachment 159466 Here it is with the OEM flywheel for your reference Attachment 159467 Turbo fitment is still tight especially on the turbine side. That line will have to be relocated for sure. Attachment 159468 And finally, the finalized engine position. Gotta love that RB tilt! Attachment 159469 Update 13-12-2012: Intercooler mounting in progress Attachment 159470 Bumper bracket modification in progress Attachment 159471 Attachment 159472 Intake manifold inlet customzed for better throttle body fitment Attachment 159473 Still not sure what I'm going to be doing with this SOB.. would hammering the body out a few mm's hurt so much? Attachment 159474 And finally some beauty shots by Docaam Attachment 159475 Attachment 159476 Attachment 159477 Update 15-12-2012: Throttle body install.. check Attachment 159478 Intercooler install.. check Attachment 159479 Bumper bracket fitment, triple check! Attachment 159480 Attachment 159481 Attachment 159482 Looks like Santa's here early.. Spec stage 5 clutch and Aluminum Flywheel :JAMIN: Attachment 159483 BC Racing Coils! Attachment 159484 Update 17-12-2012: More toys have come in!! Looks like I've been a very good boy this year :D Attachment 159485 |

Update 20-12-2012:
Awww dayum look what showed up! Attachment 159382 Engine bay blasted and cleaned with every detergent on the planet! Haven't seen it this clean in 5 years haha Attachment 159383 Engine and transmission mounts, welded and painted ready to go back in Attachment 159384 Poor crankcase was cut and welded 270 times before they got it perfect. Will be prepped and painted to look OEM again. Attachment 159385 Oil temperature sensor thread Attachment 159386 Transmission spacer surfaced and painted to match the engine block. Stealth mode baby! http://i451.photobucket.com/albums/q...220_191742.jpg Eibach fronts without the engine & transmission for those wondering :D Attachment 159387 Update 23-12-2012: Everything has been bolted together and should be going in today! Transmission spacer installed, clutch and flywheel are in too! Attachment 159388 Wastegate flange welded Attachment 159389 Transmission mount spacer, OEM style baby! Attachment 159390 Pics of the crankcase Attachment 159391 Attachment 159392 Attachment 159393 Attachment 159394 Crank case painted, oil cooler/filter relocation in place Attachment 159395 Attachment 159396 Now here's the horrible part.. there was a major communication issue over the phone about what I wanted to paint my intake manifold.. here's how it came out . . . . . . . . . . Attachment 159397 :eek::eek::eek: Update 24-12-2012: Engine & Transmission are in! That purple manifold is slowly growing on me to be honest. What do you think? http://i451.photobucket.com/albums/q...p/DSCN0533.jpg Engine mounts looking good Attachment 159398 Just can't get enough of this engine Attachment 159399 Aftermarket swaybars shouldn't be a problem I guess Attachment 159400 Update 26-12-2012: Intercooler piping check! Attachment 159401 Keeps getting tighter! (that's what she said) Attachment 159402 Attachment 159403 Tomei fuel rail and ID injectors are in place Attachment 159404 Turbo oil feed Attachment 159405 Update 28-12-2012: OEM foot e-brake out, R33 clutch pedal to replace it. I'm going to the scrap yard tomorrow to try and find a G37/370Z clutch pedal as it would hopefully be a direct swap. Attachment 159406 Tial BOV.. :D Attachment 159407 Intercooler piping almost done Attachment 159408 Turbo clearance "slightly" better Attachment 159409 Power steering pump pulley is too close to the radiator fans, the mechanic is thinking of throwing in a small spacer to push it further out Attachment 159410 Attachment 159411 Fuel rail with the injectors in Attachment 159412 Cam angle sensor Attachment 159413 Thread made for water temp sensor Attachment 159414 Hmmm... which wastegate spring to go for.. Attachment 159415 Attachment 159416 Driveshaft customization done! Attachment 159417 http://i451.photobucket.com/albums/q...m/DSCN0553.jpg Transmission spacer Attachment 159418 We're getting somewhere! Attachment 159419 Update 30-12-2012: Oil filter relocator, check! Attachment 159420 Aeromotive Fuel Regulator.. check! Attachment 159421 Some more holes had to be made.. Attachment 159422 For the clutch master cylinder, can't get more JDM yo! Attachment 159423 Update 31-12-2012 My shift knob is here :D Attachment 159424 That sway bar is a little too close to what looks like an idler pulley, wonder if it can be relocated. Bummer I was hoping to go with thicker sways. Attachment 159425 Customized adapter for the clutch pedal Attachment 159426 And another one for the accelerator Attachment 159427 Here's what it all looks like, will have to get the clutch pedal aligned later on! http://i451.photobucket.com/albums/q...ps1d1d64dd.jpg Update 08-01-2012: Great news! The car was started to check for leaks, minor leak in the turbo oil feed was fixed and MAN did it sound like a monster. Stay tuned for video's ;) If everything goes as planned she should be going for ECU wiring & exhaust fabrication tomorrow. Fingers crossed. Here are some pics for now. Oil cooler is in Attachment 159428 OEM wiring with ignition system Attachment 159429 Pedals are in and functioning properly! Attachment 159430 Close up on the accelerator pedal, was a b!tch to get right the mechanic tells me Attachment 159431 Update 15-01-2013: Wiring progress pics, not for the weak hearted lol Attachment 159432 Attachment 159433 Attachment 159434 http://i451.photobucket.com/albums/q...ps87e0b015.jpg Update 15-11-2014: She put down 485whp @ 0.9bar (low boost setting) and 615whp @ 1.6 bar (high boost setting). The car actually saw 1.7 bar when I datalogged it on the street. NOT COMPLAINING :D Here's a screenshot of the High boost run. Was too excited to adjust the Torque Axes Scale but you get the picture. Attachment 159435 I got too excited on the road and with all the boost the charge pipe eventually came off, thinking of just welding that fcker in: Attachment 159436 And here's a video of me pretending like I knew what I was doing haha |
This is going into the g I assume?
Regardless, in for updates and baddassery |
Now this is real "work"... In for updates of your project! Good luck!
|
Thanks guys, yes this will all go in the G :)

Hi Sam,
I'm pulling up my chair closer for this one. VERY interesting build. :D You assume we know what an 'RB30' is. I sure had no clue. Had to google: Wiki Nissan RB engines What is a 'pull type' gearbox? Coop |
What are your plans for engine/fuel management?

Wow, Sam. Very impressed. Props for your commitment. Looking forward to the results... :biggthumpup:
|
Didn't know you had anything like this up your sleeve Sam. Nice. Going old school. I like it. Keep us updated. Are you doing all of this work yourself or having a knowledgable shop do it?
|
Thanks Bill, J.
I'd never attempt anything like this myself to be honest, the shop doing this build is specialized in RB and 2J engines, he's done a few swaps on 350Z's before and seemed very confident about pulling this one off. All I'll be doing is lending a hand after work, getting in his way to snap pics and updating this thread :D One things for sure, he's as excited as I am about this build! |
Time to update your signature
|
Should be a fun little project. In for the build and updates. She will be a blast to drive and solid as a rock
|
Wow, this is a first! Awesome build and good luck with it all. The 350s had a little more room to work on, the g35 as well. Coming into this g37 I notice the space is SUPER tight. I hope it fits in with jus light modfcations.
The amount of boost you can run will feel amazing! |
WOW Sam. Good luck man an im all in!! Watching this thread. ;)
