RB25DET first startup video

[accelerated concepts]

Keep in mind that this video was taken as soon as the wiring was completed and the car is unpainted and the front mount intercooler hadn't arrived yet. I was starting it to make sure that I had gotten the wiring correct. Now the intercooler is here and in the car and the car is in the body shop getting worked on. I will post another video as soon as it gets out.

Here is the video (http://www.acceleratedconcepts.com/shareimage/Picture_0026.MOV)

haha lucky me... i didnt need the video..... in real life... your car sounds a whole lot better.... :D that thing is sick as hell..

you were offline before i could tell you but... parker is gonna call you tomorrow.... :) he will call you around 2:00-3:30 ish to talk to you man... P.M me for your cell... i lost your number..

Geez that was pretty slow, but still pretty cool.

Sorry for the downloading being slow. I have a cable modem so it works okay for me.

[SilviaDriver]

any wiring info would be nice!

i know u used the R33 Crossmember, R33 tranny crossmember, and custom tranny mount, what about the driveshaft?

u also stated the r33 lsd was the same as s14.

anywys..any helpful tips for people who are trying this swap?

[accelerated concepts]

well, the KA drive shaft is too long with the rb tranny installed and it has the wrong yoke on it. Fortunately, you can get a competent driveshaft place to cut the yoke from the R33 driveshaft at the welds. Pull it out of the driveshaft, cut the ka yoke of and shorten the driveshaft and weld the r33 yoke in the KA driveshaft. Umm, as far as the wiring is concerned, I can not divulge the information(for legal reasons) on exactly what wires go where, but I can give you some information that you can use to derive how to do it yourself. Below I've got some links on some sites where you can find information. Once again, I deeply apologize for not being able to tell you exactly. I know how frustrating it is to not know for sure. Trust me, I had the basic idea on how to do it myself but I asked another company to verify what I was doing and they confirmed my theory. In return, I agreed to not tell anyone for business reasons. I truly apologize. Below are the links. Thanks guys for understanding my situation. If you don't understand, then I hope that you don't get mad.

:( I cant downlaoad the video!

[accelerated concepts]

Steeles, go to apple (http://www.apple.com) and download quicktime 6 for free.

[Steeles]

I've got quicktime 6, a window pops up says its downloading and then nothing ever happens.... doh wait nevermind there it goes... maybe itjust didnt like me last night lol sounds so smooth that s awsome man!!

[accelerated concepts]

Thanks man, I appreciate it. I promise to post more updated video footage as soon as possible.

[lbcklik1486]

Sorry to be a bother, but what did you do for your ps lines?

[accelerated concepts]

I had some custom made. You should be able to get them made at a radiator repair shop.

[SilviaDriver]

of course of course..its koo man i totally understand that u cannot give any info out for legal reasons. people gotta run a business. good shit on the swap. ive been looking at this for a while now!

thanks for the LINKS!!!

[accelerated concepts]

No Problem. I will continue to look for more links that might be able to help people out.

[chucky]

i for one appreciate all of the info. I feel me and a friend are competent enough to do the swap. You have already helped alot! Most people are much more secretive. I plan on going about this swap pretty soon, when i find a good chassis. thanks again..
who is selling premade downpipes or is it a custom jobber? Do the clips come with the yolk?

Night has downpipes for the swaps. On his sit eit says they are 165$

[accelerated concepts]

We are going to be selling the downpipe from the turbo to the cat very shortly.

haha and Kick Jeremy in the butt to get the site updated!! lol

[j240sxna]

Thanks Steeles all I need is a kick in the butt:) No really, I have plans for the website.


One thing to note that I saw on Nights page is that the downpipes are not mandrel bent. Once we have ours done hey will be mandrel bent and
out of stainless so they will last. A little more expensive but you get what you pay for. We are still trying to decide whether to integrate the turbo exit pipe with the downpipe to increase clearance and smooth exhaust flow.

In any case we plan on offering lots of options for the rb swap! Heck we also have acquired rbswap.com! thsi summer things are really going to roll!

hehe you kow Im just givin ya grief man ;)

while your making piping make me a screamer pipe for the SR that'll clear the steering rack! I keep seeing them on some aus. sites but have no clue if they'll clear! I'll even be the guinea pig for um!

[j240sxna]

Sounds like plan:) we might be able to prototype one with Chris's buddy Buster. Or another thing we could do it take a stock one and use that as reference and I could use some material to represent the clearance in the 240sx. Then my fabricator/designer could build a real nice one:)
With special design notes from me. He is good with the metals and load issues.

Quick question.

I have noticed that many (ok a few) people who have done this swap all seem to use a different crossmember or motor mounts, ect.

With the various companies (You, Unstable, mckinney, night, after dark, etc) making some sort of swap kit, and no universal decision made one a standard how will you cope with these problems:

1. turbo extension to down pipe
2. motor placement do to different mounts used
3. Hood clearence for those who refuse or don't have the money to buy a new intake manifold.

These are the bigger issue because, for example some people talk about shaving parts of the turbo extension while others (unstable i think ) use custom mounts and a downpipe to fit.

I figure once you buy from a certain company, you mighthave to stick with them if you want it all to work. anyway I just want to pick your brain and any others who have ideas. Thanks.

[d240t2]

If you get the unStable mounts, you'd need the matching downpipe. With our mounts, you don't have to cut the hood...the hood clears. Downpipes won't be interchangeable with different mount kits. How often do you need to change downpipes once you have the motor in the car? Just if you did a turbo upgrade. If you got the unStable mounts with the downpipe...and later wanted to do a turbo upgrade, the downpipe could be modified by us or anyone else to fit the new setup.

It is just like the intake manifold...once you get an aftermarket one, like ours or the Greddy one...you'll be limited to intercooler kits as well. Of course, that is still better than having the uglier manifold and less efficient piping setup, IMO.

how much power do you gain from a 900$ intake manifold? i should hope it will be substantial..

[kid_nissan]

what do u use to play it media player didnt work

[Rogue]

Dennis,

Thanks for the reply, I was actually wondering if the few shops in general were trying to come up with a universal standard. I agree completely with the whole changing the turbo idea. No say someone were to upgrade to a larger turbo such as a GT2540, they would have no problem because the output flange has remained in the same area.

another question is:

has everyone used a custom driveshaft or cut and wielded theirs with the correct output shaft. I take it different kits have different placement of the outpout shaft from the tranny.

[Rogue]

aftermarket intake manifolds lend themselves well to give a big boost of upper end HP at the loss of some low/midrangepower.

Long runners = good torque
short runners = hP

this is a generalization, but most situations follow along this rule.

Cams and aftermarket manifold = nice HP.

[andrave]

I agree, the conflicting shop stuff is frustrating. I need info on the crossmember/motor mounts.
Did you use the stock mounts?
I have seen guy swith rb20det's that used the R33 crossmember and stock mounts. that won't work with the rb25det?
also, 900 bucks for a log style manifold sounds like a lot, I remember seeing the rb25 ones for around 375 on a site, I don't remember which one off the top of my head.

[Rogue]

$900 - I think that would be referring to the Greddy style which I think are 700. Jun makes a maifold for close to $2000.

Yes it is frustrating trying to understand what cross member to use with the said kits. Some use stock some use r33, r32, a31, etc.

but the cool thing is exploring the options and learning new things. =)

[d240t2]

Yeah, our intake manifolds are not the $900 ones...they are the cheaper ones. Pricing is on the website under install kits, pictures on the projects page, on Thai's car. Info on our mounts and downpipe is in the same location. As stated on the website, the mounts use the stock crossmember. www.unstable-hybrids.com

Different people have different beliefs on how to best do the install...so there will have to be different mounts and different downpipes. It is a similar situation to what KA+T guys have to do...with so many different KA+T manifolds out there...you have to match manifold/turbo with downpipe, or get a custom built downpipe.

[rps13kid]

how much did you get the motor for and what do you all have to change to drop it in a s13???

[j240sxna]

It looks like everyone is jumping to the conclusion that the rb series motors are a common and easy swap. There are tons of options. The thing that made the srswap standard was that it was designed for the car in the first place!

With the rb swap expect custom work and piping. Some companies offer better solutions to common problems with using the oem r33 crossmember. this swap isn't for everyone and isn't something that can easily done by any shop.

I plan on using some custom mounts to install the rb in my s13. Ben however used the r33 stock crossmember. It really is a preference thing. Since I am going a different route it looks like we may be offering options for several different ways of doing the swap. Most performance upgrades may not be bolt in though!

Also everyone that pans on using the side mount intercooler should reconsider. It flows good but it also doesn't fit well without cutting your car up!

I hope this helped people. I know most of this may be obvious but it drives me nuts thinking someone might jump into this swap without knowing that it is no where near a bolt in ordeal just yet.

[accelerated concepts]

The Greddy intake manifold is $900. As with the Sub-Zero intake manifold.

[fast-datsun]

WE have just added the HKS 2835 turbo kit to our shop RB25(SILINE) and everthijng clears with "our" install kit. The steering shaftis close, but clears the turbo O2 extension.
NOTE
The installation can be done several ways and it depends on the money and final results you want. You can use the RB cross and the motor fits but sit high and you have to cut the hood liner out with the stock intake. Some shops like us want the motor lower and back for clearance and weight distrubtion, but it is not a must that the way we prefeer it. I feel it provide a cleaner look also, but cars like "Nights" look good too. Its really about what you want in the end and the approach you want to use to the swap. DO YOU HOMEWORK and decide what you want and the price you want to pay before starting and you will be happy when its done.

The RB power car a fast and have lots of torque and a blast to drive. There are no reason to shy away from the swap, It not easy but Not impossible for the DIY person to do if you check all the option out there right now and pick what is right for you.

[Rogue]

Mack, with you kit does the engine ever come to close when it torques during acceleration?

[fast-datsun]

Our mounts limit the movement and hitting the shaft has not happend yet, but the use of the Shyline front crossmember does hit the O2 Housing all the time and we have factored in all the clearance we can given the space and engine size. Mack

I couldn't have said it better myself. That is always how we have felt about it. Do it however you want to do it. There are multiple ways. We like lowering the engine and moving it back for the same reasons (in addition to our experience with swaybar/oilpan clearance problems on RB20DETs). It seems like we are all in agreement here about the possibilities for RB swaps.

Hey Rogue,
As for your question on "Hood clearence for those who refuse or don't have the money to buy a new intake manifold." I know with a mount kit the intake does not hit the hood at all. I ran mine this way, while waiting for my Greddy intake.

I am working on getting custom Fiberglass and carbon Fiber hoods made with a reverse style vent to help out the guys that run a stock cross member. This way you do not have this ugly cut in your under your hood and gives a better overall look to the car. I hope to have these in a month.

Hope this helps someone,
Grumpy

[Rogue]

Thanks for the reply Grumpy and Dennis. The future looks very interesting.

[crazyikimasho]

what I need find out is what will work RB20 into s14, if I can use the r32 crossmember or not and if anyone has made custom mounts that use the s14 crossmember with custom mounts or r32 with custom mounts, etc. Thanks for the help.

What you also need to find out is that it's improper to drag up a 3 month old thread to ask a question.
What is proper is to start your own thread, and not hi-jack other people's.
