quick question, i'm sure has been answered before.

so, if you buy the after market full adjustable mounting kit for the rb20 to throw in a s13, will you still need the rb20 crossmember? granted, the clip will come with it anyway.

thanks!

The $$$ mounts are for the S13 x-member.

using the R32 x-member saves you the $$$ in mounts, although you need to notch your hood and will require special attention to the turbo elbow. Turbo wlbow may need work with the $$$ kits as well, I havn't used them before.

My front sway bar hits the oil pan a bit as well, $$$ mounts should get rid of that.

I have a previously sohc s13 that now has a rb25det (using r32 x-member and syko mount kit) I also have the Greddy intake manifold. My ? is what throttle cable have you guys used? my sohc one is not long enough.

I'm using a SOHC cable, but with your intake manifold being different you should need a different cable. I don't know which cable to reccomend, you'll have to measure and see how long you need, and nissan should be able to help you out after that.

As for the Turbo elbow/Downpipe clearance issue, I have found a solution!

Pics and description will come as soon as I get longer bolts to make sure it works as it should!

The throttle cable issue can be address by simply lengthening it with home depot supplies. Carl as well as others have covered it in these forums.

Alright so the FSM states to lube the CAS. What lube should be used? I was thinking white lithium grease.

rb26dett into s13

Postby Butters08 » Mon Aug 04, 2008 11:27 am

i am doing an rb26dett into an s13 and had some trouble fitting the rb25 oil pan on that i was told to buy. first off the 25 pan is too shallow be about a half inch for the 26 oil pickup. also the baffling plates on the motor and the oil pan do not allow clearance in the rear. to fix this i used a n sr20 oil pick up and it bolts right up perfectly. and simply broke the spot welds of the rear baffles on the oil pan and removed the rear baffles fins on the motor itself. the edge of the oil pan touching the pickup needs to be beat out a little bit and the lip flattened with new hole drilled to fit the factory holes . any questions just reply cause this all worked for me.

Just wondering, Would I need an aftermarket Radiator/specific for the RB25 swap? Could I use just new radiator hoses for my KA24 Aluminum Radiator? Im asking becuase the list does not specify and it would suck to have to buy a new one.

i would strongly recomend using an aftermarket koyo rad that is for the ka cause that will bolt right in and the outletswill match that of the 25 and of course get new rad hoses a total of 325 dollar may be spent but its very well worth it.

for the swap i would at least do ac delete cause that will ease some trouble of fitting the motor. tophatperfomance.com has motor mounts for the 25 and 26 that are only 299.00 dolla and they are pretty decent and can save you money. also i would buy a new slave cylinder cause they usually cut those off. they are like 60 bucks. when i think of more i'll let you know

Sounds good, If I were to get the tophat mounts, I would have to go to a local shop for the driveshaft correct? or would the mckinney shaft work?

when you go to put in your rb using the top hat mounts they will tell you u only need to knock about an inch on the passenger side firewall but they are lying. i found out the hard way cause i had to pull my 26 out 5 times and keep hammering until it fit just right. so basically knock it out all around as much as possible.

Well considering I am doing the RB25 swap into a S14, would I have to hammer it?

Where exactly would I have to hammer it? Right above the tranny, where it meets with the engine? I really do appreciate the advice, thanks.

Damn it, I was hoping that the RB26dett swap would stay under 4 or 5 k. That is if I can find an RB26dett for under 1k which is possible with the right connections. How much have you guys spent on the RB swap?

it's not cheap at all to do it right man, I spent $4,500+ just doing an RB20 swap. Add another 2k easy for an RB26, I usually say prepare to spend 10k on doing an Rb26 swap properly.

So far ive spent 2100 on the rb. My guess is 4500-5500 when its all said and done; which i have deduced means i have quite a bit left
