Ok here is the plan. After I am done building the house I will lay into the s14 like a fat kid on cake.BUT, I want to be somewhat prepared and have done so buy searching all material I can find but need some yes or no's, or just some pearls of wisdom from the experienced. "Here we go" as the plumber said.

Gen Info: Will be a s14 RHD RB26deTT with around 450whp.

1. I absolutely CANNOT us the RB26 transmission- B/c of the awd t mount...2. With the RHD conv. I can utilize the Twin Turbo's!!VroomVroom.3. The Rb25det transmission is more than capable of 500hp need as a DD.4.RB26dett us to be called Zues's Lightning bolt <b/c of it's badassery.Q'sOne. Is the 26 swap similar to the 25 swap into s13-ok I know not a mirror but would it be a waist to study that swap dvd for tips? also wiring.2. The R32 or 33 gauge which is best or can I use factory with some tuning.Thr3. Anymore info I can study in the mean time would be appreciated and thanks niconauts

If you have no knowledge of the swap or intimate details then don't post unless it's constructive....or funny.

You need to learn to read the stickies.. at the top of the 20/25/26 forum. (ok, I'm feeling generous)zerothread/185294http://forums.nicoclub ... ead/110509

You can use the 26 transmission and remove the front output from the transfer case, but if your motorset does not come with one, use a 25 or Z32 NA.

Why RHD? Plenty of people here are retaining the factory twins in an S-chassis.

And most importantly, grammar and searching are your friends.

Ok, I have seen these, one-size-fits-all threads, and still am not sold. Only because of back and forth type conversations. The RHD swap is both for looks and ease of engine installation. Now, when these people are using twins are they using an "top-mount" manifold? But no matter the answer on that one that I am looking for is a yes or no to RHD swap making my engine swap any easier as which I'm sure it would but looking for an experienced opinion. But I do appreciate the help although I have read these.

I understand that the RHD swap in and of self is a task the requires fabrication and welding. But, it is a look that I want to achieve, much like painting a car. Also I have read the stickies...all of them.

What I know so far is that remove Awd diff from 26 transmission and grind the ridges on the oil pan so it will clear the x-member. Or use a 25 oil pan.

I know you use the r33 gauges but some have said that with 4.08 gearing I think you can use the stock gauge with tuning using a laptop.

AGAIN, looking for experienced opinions on an s14/rb26 swap. Looking for clarity and sound of mind, a definite, "What goes up must come down".thank you..............again. Have a thumb y dont ya-

So you are cool with fabbing and welding up the chassis and firewal, switching dashes, columns, etc.... but are scared of making a downpipe or *gasp* headers to clear whatever turbo setup you want while staying LHD?

I don't understand the question about "tuning" and the gauges. Are you asking if you can tune/calibrate the gauges with a laptop?

Nay, tuning may have been a poor word choice. I know you can verify rpm's on your tach, by using a laptop. and I would rather use name brand items on it rather than noob tubing for a head. Not experienced in equal length fabbing.

Best thing to do is get a 20/25 pan and a 25 trans. Then since those stock t25/28s wont push 450 HP. Buy a good 26 single Manifold and a big single. Fab a downpipe and follow up with supporting mods.

Stay LHD unless you like to torture yourself with the headache. With the single you will have more room.

As far as gauges go you have to get a ls auto tach. Or wire up the skyline cluster.

s14 rpm gauge has enough adjustment with the POT in the back to read rpm correctly on an RB swap... I've setup working rpm gauges in 3 different s14's. S14 speedo also works perfect with the rb25det speed sensor.

I've got an ugly technique but I usually just screw with the adjustment pot and bounce the car off redline in short bursts until it bounces at 7k. caveman like but its accurate

just search just like the rest of us have, if you have a diagnostic issue go ahead and ask us but your like 2,378,967 nico member asking us what you need or how to swap an rb into a s-chassis. Im not trying to be an a s s but put yourself in our shoes and be asked the same question multiple times and it gets very old very quick.

Yeah I have seen that the Lhd method is do able but I am super partial to having twin turbo setup. Still researching turbo options to eliminate as much turbo lag as possible. So having a rhd setup seemed nice but I run the risk of ordering a front clip that has a s***ty dash when I have worked so hard to take care of this one. I want to but I'm not sure.

I completely agree man. I'm not trying to be repetitive but it seems like the rb26 write up, the more detailed ones, are almost always a 25 or a 26 into an s13. I don't want to blow money by not being prepared and learning from every available source. thanks though man

Wasn't aware that it red-lines at 7k. thank you that was another question I was thinking of buying an aftermarket s14 gauge if I couldn't find a nice R33 gauge.

Thanks guys keep 'em coming.

redline varies from engine to engine...rb20 is 7800 hard cut while the rb25 is 6900 hardcut, 26 is right about 8k hard cut.

hard cut refers to the fuel cut, soft cut is the ignition cut.

I was only talking about my personal way of setting therb25 motor redline for ~7k, should have mentioned the 26 which is 8k. the s14 gauge will still be able to measure up to 8k though... no need for gauges
