ASK your self these important questions.

1)How much money do I have to do this swap ?

2)Who will do the install ?
a-Shop.
b-You.

3)When I do buy a motor, what will be my goals with it?
a-Show.
b-Race.
c-Display.
d-Daily driver with a/c.

4) Will I be making a life changing choice with in the time period I plan to buy this RB motor packge ?

5) If I make a choice of buying the motor and I have to sell it all due to finanaces issues, how much money should I have on the side for this project?

6) How much in parts $ should I have on the side if I buy a builder RB motor.

7) What parts need to be changed out before installing an RB into my car

8) Who will do the intercooler piping.

9) Who will do the wiring

Figure a budget of $12K for the swap to be done properly for an RB26DETT swap,

Do not buy the mount kits. make your own and in the process of the swap corner balance the car while performing the swap. Will return the best results. This also goes the same for the oil pan as well.

Thanks in advance.

either use the R33 GTS-T one or an AUTOMATIC KA transmission crossmember, they are both the same. Manual KA ones do not fit properly

i was thinking of starting a RB25 project this winter and was wanting to do custom twin turbo set up... do aftermarket rb26 twin t28 style eghaust manifolds work on a rb25? i havent paid enough attention to the eghoust stud layout.. also what do you guys think about running twin gt28r s15 turbos on the rb25 with greddy intake mani q45 throttle body , mild cams , upgraded injectors and power fc?

Sounds good but also sounds costly. Pretty much sounds like a 10k project motor.

I really don't know much about rb's either and a friend of mine just got a great deal on an rb20 and was telling me that he's going twin also on that. I told him I didn't think the rb26 exhaust manifolds bolted up. After reading a little up on them a few things bolt up and are interchangeable but how about the exhaust manifold between the 20 and 26?

[bloodangels13]

first a buddy of mine is a manager at a engine import shop so the RB motorset with trans will be at s very good price, also I can get some of the parts ill need while im in thialand this summer for cheap... that and my best friend works at a local Nissan dealer so all oem parts are employee cost..(get jdm parts thru nissan motorsports hotline) plus he can get me two new gt28r turbos for a sweet deal from nissan

[Sicknick 3030]

Also check out rb-performance.net, they have an intercooler kit for rb20/25

[Yum-Yum]

will a s1/s2 shifter work for a NEO tranny? if not what about a z32?

[Oo_Skyline_oO]

already asked this question once. never got an answer...

[timlush]

Shouldn't you have figured this out BEFORE you ordered??

[timlush]

Ok, do you have to hammer in the firewall on an S14 with the Syko mount kit?

Oil starvation at high RPMs kills RBs!

The most common oiling system failures are the result of pump hardware failure and oil pickup starvation. Oil pickup starvation can cause pump failure. The best way to cause your oil pump to fail is to rev above 8000 rpm, or bounce off the rev limiter. Bouncing off the rev limiter and over-reving "shock" the pump, which will kill it in no time at all. As far as the oil pickup leading to failure, that will occur when the pickup sucks in foamy oil or air. Oil pickup starvation will occur on extreme longitudinal and/or lateral acceleration. Below is a list of some limits on the stock oil pump hardware from various generations and aftermarket companies.

* Stock BNR32 GTR pump - Max 7500 rpm. Maximum of 500whp for street or drag, and 450whp for road racing. If you decide to do a rebuild, throw the stock oil pump in the garbage and open up your wallet for a quality aftermarket pump.
* BNR33 or BNR34 wide drive pump - Max 7500 rpm. Maximum of 500whp. Throw these pumps out if you chose to do a rebuild.
* Nissan N1-spec pump - It's a stock pump with a higher rate pressure relief spring.
* Greddy pump - Max 8000 rpm. Maximum of 600whp.
* HKS pump - Max 8500 rpm. Maximum of 1000whp if drag racing, maximum of 800whp if road racing.
* Tomei pump - Max 9000rpm. Maximum of 1000whp if drag racing, maximum of 800whp if road racing. One of the most recommended aftermarket pumps available.

At the bare minimum, a quality aftermarket oilpan baffle is a must. This prevents the oil pickup from sucking foamy oil or air under hard acceleration and high G cornering. For a serious car, a quality aftermarket oil pan, combined with oil baffle, will provide the most reliability.

Oil coolers are another highly-recommended upgrade for ANY GTR, reguardless of level of modifications. The RB26 is a long engine with tons of bearing surfaces, and a cramped engine bay. Oil temperatures are already fairly hot in a stock RB26. Even Nismo bearings are unable to handle sustained oil temperatures of 110 degree's celcius. Companies like Trust, Tomei, and HKS all make excellent oil-cooling systems for the RB26.

good info, but you might want to share with other people of certain vendors online selling JUN, HKS , Tomei oil pumps just selling a stock R34 Gtr oil pump, not even an N1 pump, should share more info on how to identify them,

[godzillarb]

If I find info on how to tell the difference between the pumps I'll post that up.

But for now, to all the guys with stock pumps: don't beat too hard on your RB above 7500. A buddy of mine killed his RB26 because he was constantly hitting the rev-limiter in between shifts. 3 months later, the motor spun a bearing.

[Yum-Yum]

im using a 96' 5 speed pathfinder slave cylinder on my NEO tranny, works fine.

does anyone know the specs of this intercooler? and does it fit s14's with rb25 swaps as well?

+rep for help

www.sykoperformance.com has what you are looking for. I just got my piping from them about a week ago.

[wacerx]

ok. im trying to find a kit that sells mounts for the stock crossmember. i know that most require the R33 crossmember but i dont want to buy a entire front clip. if using the stock x-member is not encouraged does anyone know where i can get just the r33 xmember?

also Mckinney says that when they do the wire splicing they will not wire up the a/c. how hard is it to wire up the a/c?

[Tenchuu]

last time i checked syko will wire up AC for a fee. but you have to get some custom AC pieces made to make it all play together nice.


and syko makes greddy IM piping.

and try to keep questions to the boards and and FAQS here

[Rizzo]

I am getting close to finishing my swap and I am running into a couple things I have searched for but cannot find.

This was a sohc ka24e 1990 s13. putting a series 1 rb25det in with syko mounts etc,

1. what throttle cable needs to be used with this swap? will a kade work?

2 I can not find a decent wire harness. I bought one from someone on here ( knowing it had a burnt wire or 2) but the wire had burnt all the way to the ecu connector and melted a small area around that pin. I can get the harness that was originally w/ the swap which has been converted by Syko Performance but it was converted for an s14. I did not think I would have so much trouble finding a s1 rb25 harness. IF someone has a stock harness (in good cond) they want to trade plus cash for a professionally converted harness hit me up.

3 I added an Earls oil cool 13 x 4 x 2 and #10 an lines. will i need to add extra oil? When car is running will I run the chance of oil starvation without adding more oil than what the dipstick should read?

Thanks in advance for any help.
