Rb25 240 Build

[TwoHarbors240]

Finally decided to make a build thread for the S13. I've had the car for just over 4 years and until lately I have not had the funds to do as I pleased. Over the years I have upgraded a few things and started to get it where I wanted it.

To start off the plan was to rebuild the spare KA motor that I got with the car. I started looking around, doing some research and decided I would really like to have an Rb if one presented itself.

So far here are the odds and ends of the car

- KYB Front and Rear Struts
- Tein Lowering Springs (plan on coilovers soon)
- Megan Racing Rear Upper Control Arms
- Megan Racing Rear Adjustable Toe Control Arms
- Megan Racing Rear Lower Traction Rods
- Rolled and Pulled Rear Fenders
- N1 Style 3" Cat-Back Exhaust
- Shaved Antenna and Window Wiper
- 17x9 +0 5Zigen FN01rc Hyper Black Wheels (f-225/45)(r-235/45)

Here is shortly after i bought the car







Here is after fixing a couple spots on the body, shaving antenna and window wiper, 5zigens, N1 style exhaust, and lowering springs





Finishing up the body work and painting the driver side






still needs some more wet sanding/buffing







door and door handle didnt match so i had to paint it, hopefully it holds up well






How the interior sits at the moment




Some pictures after paint work was done and how it looks now







Now on to the motor part of the build. Picked up an Rb a couple days ago. Will post up the part of the build, build parts, and pics later on today. thats all for now

[Zach-sr]

Cool, clean start.

[Coolwhip]

+1 clean start. Can't wait to see the engine progress.

[Touge Whore]

Nice...good luck with the project...

[96Turbo]

Good start man. +1 for a fellow RB swapper from MN!

[TwoHarbors240]

Ok so now on to the motor. Build is pretty much complete for the most part. Im gonna change a few things and need a fuel pressure regulator, fuel pump, and a wideband and she will be ready to go. As of now the setup makes 438whp on race gas but will be tuned on pump to make it more of a daily

[96Turbo]

looks great

although I would suggest running a proper PCV system with a catch can...

[TwoHarbors240]

yeah, like i said im gonna change some things. thats also one of the options that i considered.

it definitely will get a good cleaning as well

[Edwin562]

the carbon fiber intake manifold looks beast.... u got urself a pretty dope project...

[Nick_04K]

Looks good! Maybe an inch lower haha?

Everyone else on zilvia will probably tell you to dump it like 4 inches haha.

[TwoHarbors240]

the carbon fiber intake mani was just for a mock up and test a guy did that had the motor before i did, so the manifold you see in the other pics is the one that will be used

as for lowering it, i will eventually buy some coilovers, but in my book, having a 400whp car is a little more important than hitting my shit off the ground at the moment. they will come at some point

[Imarvin240]

looking good man

[TwoHarbors240]

Thanks guys. Really looking forward to getting a good start on this. Just need to order a few things and get the race car done before i can get the 240 into the garage and pull the motor...

[HPKMotorsports3]

sweet RB... nice work, loved your paint job +1

[MattRose]

I love my RB25! What are some of the added benefits to the NEO over the series 1 RB25?

[TwoHarbors240]

The NEO head was fitted, which enabled the engine to be classified as a low emission vehicle engine due to their lower fuel consumption and emission output. The NEO head featured solid lifters rather than hydraulic, revised camshafts and a revised inlet manifold, in particular the RB25DE NEO which had 2 inlets going into the inlet manifold. The combustion chamber of the head is smaller, so GT-R spec connecting rods are used to compensate. The turbo received the larger OP6 turbine. So basically it was more efficient as well as made more power if im not mistaken

[surge s14]

looks very nice man looking forward to seeing the out come

[ChicagoS14]

Nice. I think I seen the sale thread with that motor, if its the motor I think it is then damn thats gonna be a beastly setup.

[TwoHarbors240]

Yeah it is. Motor made 438whp on race gas with the current setup. I will be retuning to have it running on pump gas before it comes out in the spring

[TwoHarbors240]

here are some parts on the list needed to finish the build

- Autometer Cobalt 160mph Speedometer
- Autometer Cobalt 10k rpm Tach
- Autometer Cobalt Wideband with o2 sensor
- Walbro 255lph Fuel Pump
- Aeromotive A1000 Fuel Pressure Regulator and Gauge
- Red Couplers all around

[TwoHarbors240]

so, ive been pondering the thought of finally getting myself some coilovers. im looking for something at a decent price, yet will still go fairly low. anyone have any opinions or thoughts?

[james626]

this is clean!!

[TwoHarbors240]

very, very small update.

cleaned up the engine really good and did some work. looks really good now, ill get pics up soon

and ordered my walbro fuel pump, turbosmart FPR gauge, and z32 Fuel Filter

[Nick_04K]

For coilovers you will just have to read one of the million coilover debate threads we have here and then just decide what you think would work best for your needs. Almost every single person on Zilvia is in disagreement about what coils are best...And it's possible because there are that many different brands/manufacturers/styles.

Im in for new engine pics though. Lets see the beauty all cleaned up.

[shortyman4065]

stance coilovers ftw.

[DoobieS13]

Megan racing streets but for a few more bucks I would go pbm... Just my opinion, I'm doin the rb swap in march/April so il be watching this pretty close. U had a really clean car to start with too lucky bastard haha but def mad props. N not to familiar w/the rb so...it's possible to buy an rb25 and then swap the NEO head and it becomes an rb25 NEO? Lookin good tho sir.

[smoked240]

Sweet build man. Another +1 for fellow Rb swapper in MN.I got mine done last month.

[TwoHarbors240]

If that is a question asking me if you can use a NEO head on a regular RB to make it the NEO, then yes from what i understand everything else was the same. they just made the head a little different for emissions and such. Idk if there is really that much of a gain from it to make it worth it though

good luck to you guys with your swaps as well!!

yeah im pretty lucky i found that car. i got that with a parts car up here in MN for 3k. Its originally a Texas car so there isnt a spec of rust on the thing. very good base to start with

[TwoHarbors240]

Got a couple of goodies in the mail today, nothin big, but still progress!

FPR Gauge and Fuel Pump

[laxrider]

Are you Ood's brother?

and that is sam's old motor right?

Damn that is gonna be one beastly car!
I will definitly be keeping an eye on this!!

I am from the Duluth Area. Might have some Tein coilovers for sale soon, if your interested?
