Been trolling the net for some definite answers, as to what Rb30 into s14 folks did/used for the engine mount issue, but seem to get conflicting info. I really don't want to knotch the hood or raise it (will if all else fails)

I am going to tackle the Rb30det this year. Just doing some early homework to what I am going to get myself into.

Can anyone post up the RB25DET into S13/S14 part #'s for the Gates heater core hoses? I cannot find them anywhere online. If you have them please post them up, thanks!

You can't find an exact part number for heater core hoses. Just ask your local parts store to take you in the back and make your own.

I just used the RB25 hose setup as well but here are a few ways to do it.

PoorMans180SX · 03-03-2014, 12:01 AM

There's a new RB25 intake manifold in town, and it means business. These are available for order from Track Day Performance now.

Question for efan setup. I got a derale dual fan controller, what side should i have turn on first? Intake side or exhaust side?

*fliprayzin240sx* · 03-09-2014, 07:30 PM

I say the intake side since most of the water will just go straight down from the inlet to the outlet pipe. Unless you have an N-type/dual pass radiator, then it wouldnt matter which side.

Makes sense, thanks flip!

Linux2501 · 03-23-2014, 08:54 PM

Alright so I got a few problems with my rb20 in my s13 and here they are.

I blew a hg on my old rb and so I went and bought another motor set and I set out to rebuild it.

Rebuilt it all Nissan gaskets water pump etc and hg head was resurfaced and cleaned along with the block it has ARP head studs but the car is on stands and so I put in new oil and filter after the rebuild and after the motor ran for about 5 minutes I took the oil cap off and I see milky looking oil in the cap and in the engine. The oil looks like tan milk after its been drained.

Why would the oil look like that after initial startup ? The head was tqed to spec 80ft/lbs

Second the vac guage reads -20 when my safc Is off and it idles fine but once I turn it on it starts idling really weird like going up to 1450 and then goes down to 500 and back up could it be my iacv or just a vac leak but once it goes down in rpm the vac goes to 10 then 5 what would cause it to do this ?

2sav · 03-25-2014, 07:17 AM

Its been awhile but ARP studs require extra torque
Idle is either Vac or Boost leak

tqed it down once and was ready to go..

2sav · 03-25-2014, 01:45 PM

^^ thats good for you
Just checked the specs. ARP instructions is 75- 80. So ur good.
Leak down test should help u track down whats really goin on with ur motor

supersayianjim · 03-25-2014, 06:24 PM

yes I forgot Linux you are supposted to tq them down in sequence.

rbeast · 03-29-2014, 10:14 PM

First of all, thanks for all the information in here.

Alright so I've got a question regarding tuning. I'm looking at a socketed Z32 ecu with a Nistune Type 2 board in it which was running the sellers series 2 RB25det. The seller seemed to think it wouldn't work on a series 1 since the coilpacks are not the same as the series 2 (1 uses an ignitor chip, 2 has them in the coilpack).

Will this ecu work with my series 1 RB25?

I didn't find any conclusive info on Nistunes website and would just like to be sure.

240Z28 · 04-18-2014, 12:06 PM

this might have been answered already, but what is the orange line on the rb trans for?

zerodameaon · 04-18-2014, 01:05 PM

RB20 trans? If so its a vent.

Boss_S14 · 04-20-2014, 07:54 PM

z32 ECU will work on both the S1 and the S2 RB25's difference between the S1 and S2 is in the coil packs. S1 has an igniter in the harness, the S2 has the igniter in each individual coil. but the Z32 ECU will run either of the two just fine.

Will an sr20 voltage regulator fit in an RB25DET series 1?? If not what its compatible as far as alternator internals????

_kouki_monster_ · 05-06-2014, 07:36 PM

So my rb20 has 2 fuel pressure regulators which one does the feed line go to the front or the rear?

_kouki_monster_ · 05-08-2014, 07:19 AM

i found my answer i guess the rear is the fuel pulse dampner, not a regulator.

Linux2501 · 05-12-2014, 12:50 PM

Alright so I just started having this problem here lately when the car is warm it seems to idle wildly and up and down by 2-300 rpm voltage drops from 13.9 to about 12.3 on my safc but on my guage and my pbm digital readout it shows 14.3-14.8 v and I thought it might be my alternator, but I work at advance and using their tester it doesnt seem to have any problems. but then again it has been wrong

My Wideband when im going into boost it usually goes and maxes out at 22. and it sputters and sometimes backfires.

So last night i went and checked the pump since i bought the car and it had alot of rust in the tank along with bad gas and I pull it out and it looks like mud on the strainer, now i do have a dw200 fp that is new and i tossed my 255 i had because the strainer fell off in the tank and i thougth it would be better to goahead and toss it for a new one.

Heres a vid of it running after it dies.

https://www.youtube.com/watch?v=TQrA...eature=mh_lolz
the motor was freshly rebuilt with arp hardware and nissan gaskets Its coming up on the 500 mile mark now and i was told after 500 miles to re torque the head. Could this possibly cause a problem.

I have been using my LEGIT hks ssqv and it was worse with the idle bouncing up and down, but when I had a old what I think is a knockoff ssqv my problem seemed to stop now after 3 days its starting to get worse like it was before.

SO i pulled the vac line off and plugged it and it solved my idle issue but it still wants to die. I had a iacv off my old rb20 that i put on it since the plug was messed up on the old one from the new motor, also I have read where it could be the ecu coolant temp sensor, I havent taken an ohm meter to it, and I also have datalogs from nissan scantech if anybody can tell anything from that.

Boost leak? I have some old couplers that have been used for a good bit. Ive been wanting to replace them along with new tclamps but I am about to get a front facing mani. Ive been told that cleaning an iacv is usually not a good idea same with cleaning a maf what would you suggest?

Bad alt
Coolant temp sensor
Iacv
Boost leak

Also I forgot to mention that i did something i usually dont do with cars but I have a coolant fan temp sensor and the switched power and the backup switch that usually goes to the a/c compressor all on an add a fuse to the fuel pump fuse slot.

Help Please.

I have a rb25det out of a 1996 gts-t. I'm trying to install it in my s14.
It has come to my attention that the upper rear timing cover/plate also known as the backplate is missing. This is the piece that goes behind the cam gears. I have been searching for a week and all I can find is one from a NEO RB25. Does anyone know if it will fit on my engine?

Sent from my iPhone using Tapatalk

Linux2501 · 05-15-2014, 09:35 PM

Alright I know I probably wont find the answer here, but after alot of time searching for the past week Ive come to this conclusion there are very few rb26dett s13s out there and nobody has done a write up about fittment. what I have gathered from picts is well duh its a tight fit same with all rbs.

I currently have swapped my s13 coupe from ka24de to Rb20det and then motor blew and pulled and replaced after a complete rebuild on the new motor.

Now I have in my hands now an RB26DETT with the 5 speed awd. I know this so far from my friends build from about 4 years ago

1. I can swap oil pan from either 20 or 25 apparently the 25 is the same as the 20 in that case i could possibly use the one i have in my garage.

2. You can use the z32 either n/a or tt but you have to swap bell housing on it.

Ive heard you can block up the awd trans but who wants to do that.

Here are my questions

1. How does the shifter line up with say mckinney mounts ? either with the rb25 or the z32 trans ?

2.Do you have to beat the tunnel out?

3.Ive heard and read that the gm 3.5 bar mafs are a better replacement to the stock n70 mafs is this true and any certain settings on the safc ?

4. has anybody on here used the arp cam bolts ? (previous issues with the rb20det cam bolts sucked ended up doing a whole day of a vice with alot of wd40 and a 10mm socket and lots of time trying to get them out.)

5. About what prices have you seen on rb26 harness and trans along with the diff have you seen?

Linux2501 · 05-18-2014, 07:45 PM

Alright So to start things off I own a 93 s13 that i saved from rusting in a field and the owner sold me a car that wouldnt start. (ka24de spun a rod of course).

I took it home and I cleaned it up and decided an RB was the motor for me (20det) Did the swap wasnt too hard learned it was best to take the harmonic balancer off when the motor was out (after my second rb20) but now I have some money and I bought a 26 and I am not scared about my swaps since I can usually do just about everything,

The motor is coming in 2 days and I am going to buy everything to do a complete rebuild, bearings ,rods, etc.

I am currently using Mckinney motor mounts for everything I know i need a custom driveshaft and I have some more questions about the swap itself that I havent found the answers to just yet after scouring the net. and here they are.

1. Does anybody have any fitment pictures of the transmission they used and how well it fit and where the shifter ends up being and did you have to cut the shifter hole any?

2. Ive read the rb20 trans is a direct bolt on but of course those trans have their limits ive been told literally they start going out at 350hp same as the ka's but from what Ive seen with the sr trans which is the same internals as the rb and the ka ive seen them hold up to 500hp I would like a 25 trans but seeing they go for about 1k or more now a days

3. I am thinking about using my current fmic but piping would be all retarded. cx racing makes the kit for the s30's but havent really found much other than the kit that mckinney has on their site for 750.00

4. Ebay lhd twin down pipes ive seen them dirt cheep and have been considering. the elbows and the down pipe for the 26 since i have had good luck out of the one on my swap that I have now even though I hate buying crap off of ebay.

5. Mount kits I have only seen what mckinney has to offer and I love their products but I have been wondering about what else is out there. Zero lift has a kit and I am sure there are more kits out there but what would you recommend

6. Ecus I am looking at a power fc, emanage , and looking at nistune the motor possibly doesnt have an ecu but I am looking for something that I can use I have been told by alot of people if i was to get any ecu get a mines ecu which i have found several, what is so special about them? do they support all things on a stock or is it a certain motor like the 26 n1?

I have done alot of searches and I have not found the information that I want to know. I would like to test fit but I kind of cant since both of my s13s are running fine even my 20 which is really rare. lol.

Please Help me.

I took it home and I cleaned it up and decided an RB was the motor for me (20det) Did the swap wasnt too hard learned it was best to take the harmonic balancer off when the motor was out (after my second rb20) but now I have some money and I bought a 26 and I am not scared about my swaps since I can usually do just about everything, The motor is coming in 2 days and I am going to buy everything to do a complete rebuild, bearings ,rods, etc. I am currently using Mckinney motor mounts for everything I know i need a custom driveshaft and I have some more questions about the swap itself that I havent found the answers to just yet after scouring the net. and here they are. 1. Does anybody have any fitment pictures of the transmission they used and how well it fit and where the shifter ends up being and did you have to cut the shifter hole any? 2. Ive read the rb20 trans is a direct bolt on but of course those trans have their limits ive been told literally they start going out at 350hp same as the ka's but from what Ive seen with the sr trans which is the same internals as the rb and the ka ive seen them hold up to 500hp I would like a 25 trans but seeing they go for about 1k or more now a days 3. I am thinking about using my current fmic but piping would be all retarded. cx racing makes the kit for the s30's but havent really found much other than the kit that mckinney has on their site for 750.00 4. Ebay lhd twin down pipes ive seen them dirt cheep and have been considering. the elbows and the down pipe for the 26 since i have had good luck out of the one on my swap that I have now even though I hate buying crap off of ebay. 5. Mount kits I have only seen what mckinney has to offer and I love their products but I have been wondering about what else is out there. Zero lift has a kit and I am sure there are more kits out there but what would you recommend 6. Ecus I am looking at a power fc, emanage , and looking at nistune the motor possibly doesnt have an ecu but I am looking for something that I can use I have been told by alot of people if i was to get any ecu get a mines ecu which i have found several, what is so special about them? do they support all things on a stock or is it a certain motor like the 26 n1? I have done alot of searches and I have not found the information that I want to know. I would like to test fit but I kind of cant since both of my s13s are running fine even my 20 which is really rare. lol. Please Help me.
