alright, i'm set on swapping an rb25det into my recently purchased rps13.  what i really need to know is the specific length for a driveshaft that must be fabricated, dimensions for piping, and just about anything else that has to be custom made.  also, would ne one know the wiring set up? btw i'm purchasing a full front clip.

the engine cradle may have to be custom. from what ive heard there is alot of cutting and welding,. to make it bolt in correct. but it is gonna be fast, good luck.

o, i do see that the intake manifold goes over the valve cover.  Does this present any problems, i can guess a few, clearance and future mods.  Would it be wise to purchase (if i can find) a straight intake manifold or have one made?

While there have been rumors of the engine mount locations being similar on the block of the 4/FWD and RWD versions of the SR20DET, there are other complications such as the starter that prevent any easy install of a GTi-R engine into a RWD S-chassis. Next best thing is to do what I'm doing, scavenge the intake mani, valvetrain and turbo from the GTi-R and fit it to the RWD SR20DET. I still have never seen nor read anything conclusive about the GTi-R internals being any stronger or having different CR.

4/FWD SR20DET's like the GTi-R engine are best suited for FWD USDM swaps. There have been times I've been tempted to buy a newer Altima (not the newest), and drop in a GTi-R or an X-Trail motor mated to the 4WD rear subframe drivetrain of the Bluebird SSS. WRX what?

actually altimas have diff engine mount locations thats why so few have swapped in sr's however you see se-r people swapping in det's

you can swap the block of a gtir with a rwd det, though i have no solid info the gtir is a stronger engine from what ive read. it did handle higher hp than a regular fwd det.

Wasn't sure if the blocks were completely interchangeable or not. I have read something about casting differences, but unfortunately my GTi-R motor and SR are in 2 different shops so I can't compare them side to side for any external casting differences. As for higher hp, tell that to the guy I bought my blown GTi-R engine from. Big end of the conrod sticking out of the block... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'> hehehehe! The valvetrain of the GTi-R is stronger, but power-wise the main benefits are improved throttle response from the ITB's and more hp from the T28.

Maybe you haven't realized this yet but rb's into 240's isn't really a well documented swap. You'll be hard pressed to find anymore than rumors and opinions here. Personaly I only know of one person who's done that. All this driveshaft mumbo jumbo and gimmie specs on this, is stuff you more than likley gonna have to find out on your own.

Hopefully you at least know these points by now.

1, Custom fab different cross member
2, Tranny is longer so you might have to ream out the floorboard
3, Turbo will more than likley hit your steering rack
4, Powersteering will probably not fit, or AC for that matter
5, Custom Fab downpipe and turbo extension
6, Custom Fab tranny mount
7, Custom Fab engine mounts

This is stuff that i know and I have never seen this done. The reason why I say this is because there are probably countless things that I didn't mention. Things that you'll find when your knee deep in a swap.

I'm not trying to discourage you or flame you. I just want you to know that this isn't some run of the mill engine swap.

Don't go saying how you know your sh*t cause frankley if you did you wouldn't be asking these types of questions.

Agreed... I only know one person as well that's done this, but it was an RB20.  Nicely done work too. .very clean, it looked like the RB CAME in the car.  Ask Jason Stonebraker, or anyone else at unstable-hybrids.com...  I'm sure they can help..  They'll even install it for you, and that's not too bad. =)

Here are some facts...........
Thanx Foxcolt.......
1, Custom fab different cross member>>>>NO

2, Tranny is longer so you might have to ream out the floorboard>>>>NO

3, Turbo will more than likley hit your steering rack>>>NO

4, Powersteering will probably not fit, or AC for that matter>>> Powering steering,  you'll keep it with our kit>>>AC No as of right now.  Working on it.

5, Custom Fab downpipe and turbo extension>>Yes custom down pipe needed
6, Custom Fab tranny mount>>>YES
7, Custom Fab engine mounts>>>YES

A custom driveshaft needed.  We build a one piece one for you.

I hope this helps you,

yeah, foxcolt, i totally realize where you are coming from, and i do understand that this is a not so well documented swap.  I much rather do the swap myself because it gives me something to do and i feel i wouldnt deserve the car if i didn't do it myself.  and yes, i don't know my sh*t, reasons why i am asking for advice and help.  I know it is possible and i know a few people on this board and other boards have completed this swap, so thats why i am asking if they would like to share some knowledge.  I appreciate all the help and knowledge people are willing to share and much props to them.

Wow a kit huh?

With this kit will it require welding or does it turn everything into a bolt in affair?

Now I'm very intereseted, I love my SR but the thought of an RB in my s14 makes me shiver <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/laugh.gif" border="0" valign="absmiddle" alt=':laugh:'>

Edit: Just checked out your site for some info. Could you provide me/us with details on this kit? What exactly does it come with, price availability, Install issues etc. The more info the better.

That's cool, with that atitude and a little determination you'll have no prob doing your swap. One problem though.

People don't give away this kind of info. Apparently I was wrong on a lot of my assumptions about this swap. My assumtions were made from listing to people with experience on this subject. But details along with wiring diagrams etc etc are not givin freely anymore.

Someone on the email list said it well a long time ago.

Hey Foxcolt,

 The kit is going to come with:
New motor mounts (Bolt in. Just incase you need to remove the RB)
New tranny mounts.
New drive shaft.
A new control boxes to make the guage cluster work and read correctly.
And we will rewire your wireharness.

 As for the Intercooler piping and stuff.  We are unsure at the moment because there are so many differnt coolers to use to make just one type of piping.  I am thinking of just including the top pipes for the cooler.  What do you guys think.

I want to make this as easy as possible for the "Do it Yourself Guys".  The kit should be ready by January.

 On a side note:  I have S13 Silvia front end conversion instock (N=8) if anyone is interested.

So the motor mounts will bolt into the stock location on our cars?

What would be great is if you can make a hot pipe to mount where any bolt in SR intercooler would go. Then make a small extension that will bolt in the cold pipe from an SR intercooler like greddy to the throttle body of the RB. That would be the cheapest route to go for you guys cause you could also sell SR intercoolers in the kit.

Will you guys rewire the KA harness? I would assume so. How bout rewiring an SR harness already modified for a usdm car. Is that possible?

How bout the downpipe and turbo extension? Will it bolt up to our stock exhausts? How's clearence with the steering rack?

Thanks,

I haven't had my SR 6 months and now I'm considering a different motor. What the hecks wrong with me!

Edit: How bout radiator lines? Did you just use new hoses on an sr rad? How did that work?
And how bout the rear heater lines from the back of the block? Were they hard to hookup?
Sorry about so many questions <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/turn.gif" border="0" valign="absmiddle" alt=':turn:'>

Yes, the motor will just bolt in with our motor mount kit.

I can use like the Greddy SR cooler kit and make the pipes work from that. One thing, the above picture is Stage 2. The aftermarket Greddy intake and the Q45 trottle body.
Here is what the stock intake and piping would look like with a front mount cooler.

http://speedoptions.com/events/971/pic154.jpg

The RB harness will be rewired to work with the USDM 240 harness.

Our downpipe will bolt up to the stock exhausts with out any issues. Also, it clears the steering rack with no issues.

I had the Stock KA radiator in the pictures you see above. No overheating issues at all. I am using a 2750CFM fan in the front as a pusher.

Stock KA lower hose but will need a newer one up top. A KA can be modified to fit. The heater lines are no problem at all. Kind of a pain to put on but the will work. I am trying to get the AC figured out so that people can keep theirs if they wanted too.
