Rb25 swap help! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

banshee_rider909 · 03-07-2012, 09:03 AM

Alright so im about ready to do a swap on my 95 zenki
here is a list of things i already have

rb25 complete motor(wiring harness & ecu)+ complete tranny

godspeed rb25 radiator for s14

godspeed fmic kit

just wondering what else do i need, i know i need the mounts but which ones are reliable and at a good price? And please if there is anything else i need let me know. Would greatly appreciate it

89JDM240sx · 03-07-2012, 09:37 AM

The best mounts you can use are the Skyo Mount kit not expensive and they give you the elbow to clear the steering column... I'm using these in my S13 they are ridiculously strong...

U need a skyline TT, Supra TT, or 300zx fuel filter... 255lph fuel pump or higher depending on power goals

Your best bet is to also source a R33 crossmember for your swap it'll position the motor back more in the engine bay

Oem gasket kit, water pump, and oil pump wouldn't be a bad idea before you drop it in

O and I forgot 1pc driveshaft

banshee_rider909 · 03-07-2012, 01:25 PM

Ah thanks man!!!! I really thought I just needed the mounts and that's all but thanks for the info. Hopefully I don't have to spend another 1k

this swap is money lol

89JDM240sx · 03-07-2012, 01:45 PM

I feel your pain brotha... Lol keep us posted

banshee_rider909 · 03-08-2012, 10:00 AM

As of right now I'm just going to do nothing but bolt ons and a good tune. I know these motors can reach an easy 400hp on nothing but bolt ons. So fuck it RB swap is an expensive swap but oh we'll ME LIKeY they RB XD I'll post pics up of the motor as soon as it gets here

SPL-Hatch · 03-08-2012, 10:15 AM

this swap is so well documented. look it up man. you need hella more shit. and you will be spending another 1k+

89JDM240sx · 03-08-2012, 10:47 AM

Where are you getting the motor from? Friend or engine place... Highly suggest refreshing the motor if you plan on touching 400hp

EnemyS15 · 03-08-2012, 11:05 AM

All i used:
R33 cross member
Syko mount kit (if you go this route, you will need a auto tranny member or r33 tranny cross member)
Upgraded fuel filter and fuel pump
1 piece drive shaft
Down pipe
Intercooler piping
Turbo timer
Boost controller. Both of these are for preventive measures.
A/F controller if you got bigger injectors
Fpr

And replacing the standard stuff , timing belt, oil pump , fluids, belts, etc.

If you are going wild with it like I am:

Wastegate
Bigger turbo
Modify oem mani or go with a quality exhaust manifold.. Love fab, 6boost, raw brokerage, or if you have the big monies, go full race
Some sort of engine management.... Haltech loves rb's ;-)
Cams with decent lift
Q45 tb
Freddy or greddy intake mani or just mod the oem like some do..(not a fan of it)
Replace oem coil packs with upgraded or go ls1 for series 2 Rb
Bigger rail with 700+ injectors
Something bigger than 255 walboro for fuel pump
Forge pistons , I've always been a big believer of not boring out the motor if you are going 500hp or less. <---- only applies to Rb.
Clutch

1k won't get you too far in terms of Rb parts. The only thing that is consistent with all Rb owners is Rb is a very expensive, but fun motor.

+1 good info

banshee_rider909 · 03-08-2012, 08:36 PM

+10000000000000 thanks for the info bro. As of now (due to money) I just want 400hp thanks guys. I'll keep you guys posted on this project

redline racer510 · 03-08-2012, 11:09 PM

Get ready to spend another 3-4k. Its the small things that end up being the most expensive, they really add up. Have someone professionally do your wiring harness. Wanted to try this.

LOL, seriously right?

mantas · 03-09-2012, 12:02 AM

Hahah so true. Rb swap info is everywhere. But for starters, use 300zx 93-96 filter for oil and fuel. Move the battery to the trunk to create more room in the engine bay. You can get away with just the r33 crossmember but make sure you hammer our the firewall where the transmission tunnel is and grind down the turbo elbow for clearance to the steering column. And get ready to not be impressed when you fire it up on the stock ecu. The stock ecu is garbage. Also i highly recommend a bigger radiator and running the rb25 clutch fan for which you might need to cut the radiator support.

EnemyS15 · 03-09-2012, 10:36 PM

. Syko kits also come with turbo elbow that clears the steering, no need to gring the elbow.

banshee_rider909 · 03-12-2012, 12:59 PM

alright guys need help once more i will post this up on the WTB thread but just wondering if anyone has a r33 corssmember for sale! LMK

mantas · 03-12-2012, 06:52 PM

Look on rawbrokerage.com i recall seeing one there or it could have been NICO. But get mckinney or syko mounts, you will save yourself many headaches in the future - trust me i wish i had a mount kit instead of my current set up.

Give Russell a call, you can get a BNIB Crossmember

NissanParts.cc - Your #1 Source for OEM Parts and Accessories

banshee_rider909 · 03-12-2012, 09:18 PM

the syko motormount kit only fits for the rb33 crossmember. if his crossmember is a replica of a r33 and same quality or stronger then i shall call him =]

alright guys so after a little mishap with the freight i finally got my motor!!!!!
tigerjapanese.com is a real good place to get your jdm motors and front clips =]

sorry that its still wrapped, its been raining here in socal

greenmachine300zxtt · 03-27-2012, 10:35 AM

The syko kit is an excellent kit, but i use mckinney motor mounts on my s14 rb swap with no problems at all. Good luck and have fun with your build!

banshee_rider909 · 03-27-2012, 11:26 AM

Honestly what's the difference in positioning between the r33 crossmember with the SYKO, and just using mckinneys?

banshee_rider909 · 03-29-2012, 09:36 AM

its coming closer to d-day. i just ordered the cross member right now =].....oh and i alos got a gerett turbo to replace the nissan turbo =]

banshee_rider909 · 04-06-2012, 12:25 PM

Alright you zilvia freaks =]
i have evrthing ready for install just wondering where the good shops are here in socal
or if anyone can swap the rb25 with wiring(i need someone who really knows their shit, no mickey mouse please) LMK PLEASE AND THANK YOU!

banshee_rider909 · 05-19-2012, 08:14 PM

ok here is a list of things i already have

rb25motor and tranny
ecu and wiring harness
godspeed aluminum radiator
syko motor mount kit
greddy turbo timer
greddy boost controller
r33 crossmember
godspeed front mount intercooler

any other things?

89JDM240sx · 05-19-2012, 08:22 PM

Drive shaft, fuel filter, fuel pump, power steering lines if you choose to keep it... What harness are you use? The factory Rb or wiring specialities... Etc?

mantas · 05-19-2012, 09:44 PM

Seriously syko are best mounts i wish i went that route. I just did and r33 croasmember and driveshaft and custom tranny mount but if i did it again - syko. No mckinney unless you have a small brain.

banshee_rider909 · 05-19-2012, 10:08 PM

so i really don't want to have splicing problems..if i recall chase bay makes custom plug in harness for the rb25 swap correct?..and how high of a fuel pump do i need? oh yeah drive shaft will be taken care of after motor is in..just want to know wha else i need to have it on not rolling lol

89JDM240sx · 05-20-2012, 05:48 AM

Don't use chase bays... Get a Wiring specialties harness... Fuel pump look into a Bosch 44 or Aeromotive for the goals you want
