a few rb questions

Post by **silviadreams** » Mon Oct 20, 2003 9:24 pm

I did some searching around, so before you flame me and tell me do go do a search please just read my simple questions. Ive seen the rb25 install kits, I think from http://www.supertunermotorsports.com and the kit is only 695 dollars. -Other than mounts and harnesses is this a drop in swap?-Will I need a custom drive shaft?-Can a use an rb rear diff?-Is there welding involved?-Ive done swaps before, but mostly hondas.. and those are a walk in the park. What kind of difficulty level am I looking at with this project?-Approximately how much time will it take with one helper?-What kind of difficulties have you run into with your rb25?-Other than the cost of install, and cost of the clip, how much more would you say it would cost to complete this project?

Suggestions, comments and critisizms are always helpful, If anyone is willing to aid me in any way it would be greatly appreciated.

uh ok, I did some more research and I got like all of those answered except for the time issue.. no one really gives an ETA

Depedsn on how in depth you wanna go. Besides getting a driveshaft madde for teh RB25 (unless you buy one), the swap is can be pretty straight forward. Are you going to do routien maintenance or in deoth maintenace. I did nothign and it took us 3 days to install. We worked around what 8 hours a day McAdam???

Post by **JonPowell** » Mon Oct 20, 2003 9:24 pm

I can see the swap taking about 3 days, like you said. I went WAY in depth with my swap and including having to get a second motor and fully weldinging & painting the car it took 7 months.

A friend has an RB25DET on the way and he is getting the Supertuner mounts so I will let you know from there how it goes, probably end of the month/beginning of next month.

I AM TAKING THE LONG ROUTE TO UNDERSTAND EVERYTHING ABOUT THE MOTOR AND CAR. BUT IF YOU HAVE ALL THE PARTS LYING OUT AND READY TO GO AND YOU KNOW WHAT YOUR DOING YOU COULD HAVE THE CAR SWAPPED AND RUNNING IN 3-4HOURS, OTHER WISE IT'LL TAKE SOME TIME.

I wsh I had taken my time and done in depth maintenace. Would ahe saved me some heartache. I may be doin ganohter swap (it wont be Nissan though) and I WILL take my time. Everything will changed. Head gasket. Timing belt. Clutch, flywheel...EVERYTHING. That wuld be my suggestion. Had I replaced that stuff, sure it would have been an *** of money, but it would also have given me piece of mind. And piece of mind is killer

I DID IT TO KNOW WHERE ALL THE NUTS AND BOLTS ARE, WHAT THE FASTEST ROUTE IS TO CHANGE COMMON THINGS, WHAT AREAS NEED IMPROVEMENT, KNOW WHAT EVERY SENSOR IS AND WHAT I'M SPLICING ON THE 240.

Post by **silviadreams** » Mon Oct 20, 2003 9:24 pm

yeah I do really want to do the maintenance.. clutch.. flywheel, headgasket, water pump.. Other than the cost of the motor, how much on top of that did it take you to just get it into the car? And.. did you make your own driveshaft or did you buy it?

Post by **spec-v5150** » Mon Oct 20, 2003 9:24 pm

Well I have an RB20, so there is no need for a driveshaft. Here were my after motor exspenses

$90-2 10" electric fans (get at least 12" in my opinion)$90-fuel pump (never installed it, but recommended)$30-boost gauge$35-water temp gauge$15-6 spark plugs $35-triple gauge pod$50-Aftermarket tach (not needed if you get a RB cluster)$500-Instal help. McAdam of these boards lent a HUGE helping hand plus brought down his cool tools. Thanks Again!!!)I am sure I am missing something...cant think right now. But that is the gist of it

Post by **wcbjr** » Mon Oct 20, 2003 9:24 pm

Here's a list I have come up with that I have done / will be doing for my RB20.

Code: Select all

Clip:  Motor  Transmission  ECU  Harness  Intake  Filter----------------------                $ 1500

  Turbo         $  395  Manifold      $  300  Head gasket   $  250  Head studs    $  180  Injectors     $  140  Water pump    $   86  Timing belt   $   56  Thermostat    $   10  Fuel filter   $   10  Oil filter    $    8

Not yet purchased:  240sx LOL     $ 2500  Intercooler   $  700  Gauges        $  500  Computer      $  300  Clutch        $  300  Downpipe      $  240  Catback       $  200  BOV           $  200  Radiator fan  $  200  Airflow meter $  180  Fuel pump     $  180  I/E gaskets   $   20  Spark plugs   $   15

I don't know if a Walbro will drop into the 240's pump, that's why it's so high. Haven't priced radiator fans, its kinda high. May have to get the flywheel resurfaced. Cool thing is the clip came with coilovers and wheels/tires. Don't need to buy those.

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

HERES THE BREAK DOWN SO FAR

$1560 FOR FRONT CLIP$35 PLATINUM PLUGS$80 OIL & FUEL FILTER, HOSES, CLAMPS, ZIPTIES, WIRE LOOM, HEAT SHRINK, ETC.$50 BRAKE CLEANER, RTV, SILICONE SEAL, AND THAT COPPER SEALANT.$150 IC PIPING$93 14" 2950 CFM FAN$80 POWER STEERING LINES$225 FMIC$50 HKS FOAM FILTER AND ADAPTER PLATE$90 FUEL PUMP

THATS ALL I CAN THINK OF FOR NOW AND THERE IS STILL SOME MORE THINGS I NEED TO DO.

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

do NOT buy from supertunermotorsports

their mounts dont fit, dont do what they advertise when you fix what they did wrong with them and their wiring "7 day turnaround" is over a month for myself and a friend.

spend the money and go with mckinney.

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

I COULD HELP YOU WITH YOUR WIRING IF YOU HAVE BASIC ELECTRICAL SKILLS (IE: STIPPING, CRIMPING, HEAT SHRINKING, ETC.). YOU DON'T NEED MOUNTS, THE DP IS THE SAME, THE DRIVESHAFT JUST NEEDS TO BE MADE/PURCHASED.

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

here is the thing.

i know how to wire, i know how to read diagrams. i went with them because i wanted it done fast to save headaches because nobody can give you a direct answer on how to wire a 97 240sx to a 96 rb25det with a type II ignition.

im using a RB20 transmission so i went with their mounts because it was supposed to move the motor back so i wouldnt need to deal with a custom driveshaft.

all this damn time ive wasted i could have figured out the wiring for myself.

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

TYPE 2 IGNITION?

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

yes, type II ignition.

just an example, my igniter is contained within each coil pack. so i dont have one on the top of my spark plug cover.

Dont need mounts? Well ****, and where are you guys getting rb25 clips for 1500 from?

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

OHH OK THATS EASY I HAD THAT ON MY RB25DE VVT. IT PRETTY MUCH THE SAME THING. DID THE STM HARNESS WORK?

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

MY CLIP IS A RB20 BUT THE MOTOR DIMENSIONS ARE THE SAME. THEY BOTH SIT ALMOST EXACTLY IN THE SAME POSITION IN THE ENGINE BAY. TO SAVE YOUR MONEY ON MOUNTS YOU NEED TO CUT THE HOOD SKELETON FOR CLEARANCE. THE DS NEEDS TO BE MADE BECAUSE THE RB25 transmission IS LONGER.

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

HEY KAMIN DO YOU HAVE A RB25 transmission?

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

no, if i did i would be using it. i dont want to use a POS rb20 transmission that wont hold 400whp.

and to do it surfmans's way silviadreams, you need the R33 crossmember AND the mounts from the r33. and clips arent 1500$ anymore, they havent been that price in almost a year. your looking at 3000+ now for a good one.

supply and demand is a *****.

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

I COULD BRING IN A WHOLE CAR FOR YOU AT A LITTLE OVER DOUBLE THAT. THAT MEENS BODY PANELS, ENGINE SET, INTERIOR, TAIL LIGHTS, WHEELS, BRAKES, LSD, ETC. AND YOU KNOW EXACTLY THE TYPE OF CAR IT IS COMING OUT OF.

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

yea well some people dont have connections in japan to have motors/cars imported.

so the market value is around 3000.

Post by **PROJECTRB240SX** » Mon Oct 20, 2003 9:24 pm

I KNOW THATS WHY I OFFERED MY SERVICES. ANYWAY YOU ARE LOOKING AT EXTREMELY HIGH PRICES BECAUSE OF THE HYPE, AVAILABLITY, AND THE DEMAND.

Post by **S13Sil-line** » Mon Oct 20, 2003 9:24 pm

Kamin, your using and rb20 transmission on a rb25 motor?

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

Post by **S13Sil-line** » Mon Oct 20, 2003 9:24 pm

Thats why it didnt bolt up. The rb20 transmission is smaller and has the mounts in a different spot. Did you call them and see what happened?

Post by **Joe** » Mon Oct 20, 2003 9:24 pm

the crossmember mounts have nothing to do with the transmission.

and those mount problems arent related to my car, they are off the other s14 rb25 hybrid that my friend is doing, we both got wiring and mounts done at STM. his is a rb25 engine and transmission. and after some measuring we concluded the motor didnt move 1 inch. damnit the motor didnt move 1/10th of an inch. and the money we spent on their mounts accomplished NOTHING other than not having to cut the hood skeleton.

and yes we have called, left messages and emails.they dont respond. i think its about time for a lawyer to get involved.

Post by **S13Sil-line** » Mon Oct 20, 2003 9:24 pm

Really. Hmm. Im not saying your wrong. Ive been talking to them and they say its the same kit they used on thier car. It looks like from the pics they are right. Im going to call them and see what up with that. Thats bs if it true. Not a good way to do business.

if you get in touch with them tell them to call krayton or email joe back in tucson.
