Ok guys, I plan on having my rb25 in hopefully 6 months. My question is, if I go ahead and get a 3" exhaust will it work well and also what options do I have? I plan on going with custom made one from my local exhaust shop, so what type of tubing should I use? Also Im goin to need a muffler, and Im kinda wanting a titanium one but it has to have the 3" inlet, so what kind should I get if I want a medium deep tone? Also will I need a resonator and whatnot? Is there anything special I should have the shop put in to get ready for the swap? I plan on having them make as few bends as possible, so will my 95 sound too ricey untill I get the 6 cylinder? Thanks for any input and advice.
Josh

My RB25 will be here by friday. This is what I suggest. Dont worry about passing emissions too much, I doubt you car will pass. Im going with a 3" staight from the downpipe to the end of the car. Nothing else. Your turbo will spool faster and ya, will kick way more ***. Anyway I suggest you wait until you get the motor in the car that way you'll have a perfect fit, and can get a good look at whats going on before you waste money. Good luck!

well, I live in alabama. the only good thing about this state is you can do whatever you want to a car and not worry about gettin in trouble. also, I beleive the rb25 hits the steering rack too, thats why I plan on getting a set of mounts from unstable hybrids for $500. I planned on running a full 3" like s13sil-line, but I kinda want to do it now and only take it to the cat and put a test pipe on. what will I have to worry about then? and also, no one suggested a good titanium muffler. thanks for all the input.

If you plan on doing the swap I highly suggest you get the swap kit from http://www.supertunermotorsports.com for about 100 dollars more you get the mounts, custom wiring harness, down pipe, radiator hose and a few other things I cant remember. The custom down pipe comes 3" and goes from the turbo to the cat.

My R33 clip will be here by friday so I havent really started the swap. I live in St. Louis and I found an exaust place about an hour away in the country that will do from the down pipe to the end of the car 3" with some kind of rust resistant steel mandrel bent for $100. Since the http://www.supertunermotorsports.com down pipe goes all the way to the cat it will end up being cheaper. Try finding a shop in the country that see a lot of "race" custom work. They'll be cheaper than one that gets tons of business in the city area.

nice, when do you expect to have that done by bige? Id love to see how it works out. where are you going to have the pipe come out at on the side? and I guess your not runnin a muffler either with that huge azz 4" piping, but it would be tight. I still want a muffler so I dont have every cop I pass wonderin why that car is so damn loud, but I have yet to find one. well, thanks for the help guys.

Without using the kit the transmission mounts will only bolt up to two of the four mount bolts. The motor will bolt in fine. Though it is a bigger motor thats why it will hit the hood and the shifter will end up being about an inch and a half or so forward. Recommended if doing a show car. But then I could call you stupid if you wernt driving the car. The kit from http://www.supertunermotorsports.com is what you want to use if you plan on driving this for anything, racing, drifting, groceries. If you go to the site you will notice they pretty much only deal with the RB swaps. They have different levels of the kit. From an all out swap kit $695, just the mount kit $375, to just the wiring harness to plug and drive at i think $150. The kit will lower the motor, now it wont touch the hood, and move the motor towards the driver, resulting in better wieght distribution and will actually end up moving the shifter back to its normal spot. All mounting bolts will bolt up perfect for a solid motorswap. Also with lowering the motor now you have more problem with the bottom of the motor hitting the sway bar. The guys at http://www.supertunermotorsports.com have that taken care of included in the kit comes aluminum spacer blocks to lower the sway bar. NICE! Also coming in the kit are transmission spacers to space apart the transmission from the underbody. I forgot to mention that if you dont use the kit, the transmission will be touching the under body of the car creating bad vibrations. Now the added wieght of the motor youve been worrying about doesnt seem so bad when the motor AND transmission fit perfect and now more wieght is pushed back. What more could anyone want out of a swap than a perfect fit. DO NOT. I MEAN DO NOT forget to replace the timing belt availible at http://www.mckinneymotorsports.com for $150. You could possibly be the dumbest person in the world "leagaly" if you blew your motor because of a dry rotted belt. Also look into a new water pump. Cost a little more but way better than wasted money on a blown motor then feeling like a vagina cuz now you have to swap from a straight 6 turbo back to the ka motor.

Ok. Now you have to buy a RB25 transmission, R33 crossmember, a radiator that will keep the rb cool with lines. Wiring harness. Heating and a/c lines, p/s lines, ecu depending on with what comes with it. If its just a motor beware of bad compression or other things internally. Oh, and be prepared for the cost of fabrication work in the engine bay to make room for the second turbo. Hey if it works, good deal. Thats a new one for me. You know. The reason I went with the R33 clip is because ya, its cheaper, and the fact everything I need is in the clip from the R33 five lug conversion to the 5 speed transmission. Also if Im lucky Ill get headlights and fenders I can sell on e-bay for more upgrades. Good luck. I would love to see pics. Are you doing an s13 or 14?

:rolleyes
Yeah, annoyingly loud...and count yourself out of running a lot of sanctioned events with the car.
You're not going to notice much if any power/spooling increase with no muffler vs. a good flowing 3" one.
But, whatever floats your boat.
'S13Sil-line wrote:Ya, like about $3,000. Take the money and do this. Turbo upgrade, bottom end, top end, fuel system. Now if you do it right you can push 800hp plus. To the wheels! It would take a 26 any day.
You're on crack.
You may want to sit down and price things out before you throw statements out there like that. For $3000, you're not gonna get close to what you're claiming here.
I'll tell you what. When you can get all of the above done correctly for anywhere NEAR $3000, I'm gonna stop building/tuning cars and send everything to you.
I think I'll be doing this for a long time to come....
S13Sil-line wrote:Dont get salty. If its a clip say its a clip. You said it was a motor. You still have to do a lot of work in the bay and get a RB25 transmission. Where did you find this clip?
dont you see the smiley face, yeah i know that you need a Rb25DET transmission or i can use a RB26DETT trans but i need to make a special plate or something, i can keep the TT's if i use the MCkinney mounting kit for the RB26, or a have someone make a custom exhaust manifold, or i can convert to a Trust T66 single turbo, using a Trust stainless steel exhaust manifold, then if i use that setup then i proable have to buy the Power FC to run everything, or reprogram the ecu, also if i keep the TT then i have to get a RB25DET oil pan and modify it, i dont remember what i have to remember to get the RB26DETT to work in a 240

If you guys have any questions seriously talk to Patrick at http://www.supertunermotorsports.com. That was his car in the mag. and he knows all about it. A little info so you save money to who ever gets an RB25. The 300zx NONTURBO clutches work. And for you s13 fans the kit works with them too. 93RPS13-Go for it man. Good luck. That one hasnt been seen. I give you props if you go through with it. To tell you the truth I'd be kinda jealous.
