I searched without luck for a solid answer, and am hoping someone can help me out. I've seen what Full Race is doing with their R14 project, and have been contemplating something similar (although hopefully with smog legal potential) that I can only call the R13. What I am looking to do is swap an R32 front clip including the AWD bits from a GTR into a USDM S13 chassis. Since there is no way at all I can hope to get an RB motor to be emissions legal in the socialist state of CA, I'm hoping to take a stab at a VG30dett swap. What I have read so far indicates that the RB25 AWD trans can be mated to a VG30DETT bellhousing. While I know I'm in for a serious ammount of fabrication, I'm hoping someone can validate that these two bits will work together.

First i hope you meant RB26 AWD trans and as far as the AWD transmission working with the vg30dett i know the RWD RB25DET transmission will work if you change the housing i just dont know about the AWD part on the RB26 transmission.

See? Thats why I'm asking questions. I guess I need some more basic info. If I understand (and please correct me if I'm wrong) the AWD cars use a... transfer case of sorts on the trans, a center diff, plus the front and rear diff to accomplish AWD. I guess what I really need to know is what parts are needed to make a Skyline AWD ad then figure out how to bash them into an S13 chassis. Sorry if this sounds remidial, but with most of the AWD cars avilable in the States based on a front drive setup, there isn't much here to study up close.

Its possible, but is it worth the time and $$$$$?? Not for the average driver. OBY the RB25 can in AWD too , in some cars......

correct, there was an AWD rb25.

but seriously, your gonna spend upwards of 20,000$ for all of that, and get what? a car thats awd but going to be beat senseless by cars with half as much invested?

cool idea but totally impractical.

Yes you can bolt a z32 bellhousing onto an RB26DETT awd transmission. I did it when I used the 26 bellhousing on the z32 trans. I wanted to protect the 26 trans so I put the z32 bell back on.

As far as a ton of cash, yes I agree. It would all be about finding the right parts at the right time. I did find a rear-ended '92 GTR on Vancouver CL for 7k, though. And with a mildly built VG30DETT, I don't think the car would be spanked THAT hard. Or often. This whole line of thought came into being after some discussion in another thread about Skyline importation and why it's nigh on impossible to get one here in the States. Cost is relative, I suppose. Either 50k plus for a legal Motorex import (of the few that made it) IF you can find one for sale, or 20k plus to build your own AWD Nissan powered bad-mobile. From what I've heard (and mentioned earlier) there is a company called Full Race building AWD conversion kits for the S14. If you can build a kit, it can't be impossible. I suppose I just need to decide how bad I want to throw money at the idea.

there is a notch on the U.S. passenger side to allow clearance for the transfer case in the skyline with awd transmission. in my opinion that is very easy obstacle to get by.

second, the r32 cross member bolts into a s14, not sure on s13. basically i'm saying use the stock skyline cross member.

so the only real hard thing to do is figure out your suspension. full-race say they have a contract with some company that makes them the custom coilovers for the R14 so ask if they can give you a set of just the coilovers.

third, even if by some chance full-race does give you those coilovers then you still have to modify the strut tower to allow the "thing", cant remember technicial name, looks like a 7 where the top part of the 7 connect to wheel well. look at full-race website of the pic where the tire is turned to the left. it is the piece next to the coilover.

the third part in my opinion is the hardest to figure out a solution for. if you want it do it.

or just weld a skyline front end to your 240

lets say 400whp.

you spent $25,000+ for 400whp.

you could do that for 1/3 the cost with any other engine, then have the extra 16+k to build the car or make more power. sr, rb, ls1, whatever. the AWD factor isnt going to magically make it unbeatable. if anything its going to sap away more power than just a RWD setup.

im sorry its just pointless to do for the average person who isnt building a show car. there is no benefit to having it other than to say "its awd" and get the "street cred"

its just my opinion, i dont like wasting money.

if you really want awd s13 it would be cheaper to actually buy an r32 gtr then to convert the s13. but thats just my opinion

The GT-R's front diff is housed in the oil pan.

I think you should quit dreaming peter pan, count chocula.

Just kidding, I just wanted to say that. This seems like a grip of trouble that isnt worth it..

not only the cost of the parts your buying but also take into consiteration the custom brackets taht you are going to need and other underlining chassis work too!
