Hey guys, before you flame the absolute shit out of me, I bought an rb20det really cheap and its much easier to find an r33 shell for a better price than an r32. i would go r32 if i could afford it.

anyway, as the title states im putting an rb20det into an r33, this includes the rb20 box aswell, besides the loom will i need to change anything else? i read on here that if you put an rb25 and box into an r32 you need to shorten the tailshaft, would this be the opposite with an r33? thanks in advance for any help, please don't bother flaming i don't really care that you don't agree with what im doing.

I won't flame you. I would just like to be the first to point out how retarded that is.

It won't be legal either.

Haha yeah good one post an opinion after i just said i don't care about them, yeah you're so funny and your epenis is huge, good job champ keep up the funny work!! I don't care that it's illegal, i can get roadworthies and without a coilpack cover most cops couldn't tell the difference anyway.

You didn't say you didn't care about opinions. You didn't want to be flamed because you know it's a retarded idea.

I'm just happy to point out the obvious.

Aside from the legalities, putting in an older smaller engine is retarded. Does that help?

Otherwise do it. Report back.

"I don't care if you don't agree with what im doing" do you understand or do you need it explained a little better?

I'm pretty well aware that there are better options, these options also cost much more. It's clearly nothing special, im not going to race every other skyline and wonder why i loose, i want something thats a bit of cheap fun. and doing this is by far the cheapest option, rb20s still go hard, i also have access to several turbo upgrades which would make up for the engine size. It's cool that you think its retarded, i don't care please stop commenting on this thread, i asked for help on what i need to modify, not your opinion.

K. Good luck man. I assume you are using the inferior rb20 box as well? As using the stronger r33 box would actually fit (it comes in the car) and be stronger.

Sounds rad. I've changed my mind. Now you've mentioned a different turbo a laggy rb20 in a boat would rule.

And Its not my opinion. It's fact. I didn't dream it up.

If i read someones post and it said "before you flame the absolute shit out of me" I would guess that said person already knows what their doing isn't the way everyone else is going. Like i already f**king know rb25s are better, i know 25 boxes are stronger, for the 3rd time I'm doing this because its cheap, if you don't like it dont reply to the thread holy f**k. is it really that hard?

No engine transplant is cheap.

Do it properly or don't do it at all. New hoses, new timing belt, new water pump, new oil seals (especially oil seals on an old drippy RB20!!!). New thermostat, etc etc. Then the wiring changes. Then the tailshaft modifications. Working out whether to use the new or old (or the opposite way around for you) power steering pump, air-con compressor, alternator (all of which have different connections to teh car between R32 and R33). Then finding the right transmission mount. Then the problem of the speedo drive.

The core cost of the engine is not as significant as you'd think.

I did a Neo transplant into R32. I did everything properly. It cost several times the cost of the engine.

But if you want to set sail in the failboat, go right ahead. The last time I saw anyone put an RB20DET into an R33 was an R33 GTS (no T) and it was LAST CENTURY....when it almost made sense.

Thanks for the reply, although cost of doing that stuff to someone like you may be major for me it is not, Im a metal fabricator by trade and have heaps of experience in the auto electrics field. The rb came with a new timing belt, starter, hoses and altenator. Speedo will be an easy fix. I can do all the mounts and modification work myself I also have several family members that are mechanics. So almost everything you listed will be extremely cheap in my situation. Where as the outright cost of a 25 engine and box is not. My main question is the tail shaft and gearbox mounting. I have been told by many people that 25 And 20 boxes are interchangeable if that's not the case I would love for someone to correct me. And the tail shaft, I was also told a non turbo r33 tail shaft would fit a 20 box but again if that's not true someone should correct me, I just want to know if there's a tail shaft shortcut or will I have to extend it myself. Thanks in advance

How about if I told you that my brother-in-law is a mechanic, that I did almost all the transplant labour myself, had access to a large pile of swappable transmission mounts, wiring loom bits etc etc?

Not so clear cut now is it?

What I told you is the truth. Believe it or not. Take our advice or not.

Yes the gearboxes are compatible. Pretty much every RB box bolts up to every other RB. But the RB20 box is weak. I destroyed the input shaft bearings on one with a mostly stock (bolt ons and some boost) RB20. That was after destroying the previous auto in it with the same power. I would never try to make more power in any Skyline these days without a 25 box behind the engine, regardless of the (turbo, obviously) engine type.

Several times the cost of the engine? A cheap Neo and box combo would be about 2.5g yeah? Explain to me how you spent over 5 grand purely on conversion costs? This doesn't include parts not needed for a conversion btw lol. Tail shaft modification, mounts, looms etc etc, over 5 grand?? "Several" so even more? Hahaha right oh wow, your brother in laws a mechanic? I also have mechanics in my family but I fail to see how you would need one if you did a conversion by yourself

Hmmmm. His workshop, his hoist, his stack of parts and looms. That's how I needed "him".

And yes. If you do stuff properly, and I don't mean cheaping out on everything, I mean buying new engine mounts, etc etc, then the costs very rapidly add up.

And no-one with half a brain buys a "cheap" Neo and box. I bought a very nice low km Neo for nearly $2k on its own. An R33 (I wouldn't use a Neo box because of the wrong clutch) box is over a grand. Then you need a flywheel (if you want to get rid of the heavy boat anchor on the original engine) possibly a clutch (although I had a good one).

So, yes, I did spend over $5k on costs. And I'm not ashamed of it.

I'm out.

friggin hell there is some retards on here. The dude quite clearly says he is aware of it not being the best option, and explains why he is doing it, to get a cheap car going. But no, everyone has to run him down and rubbish his ideas, cause it's not what 'they' would do. F&*ktards.

If you have any info to help him, post it. Otherwise STFU and quit being keyboard warriors.

    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
