Gday,

I know this has been done before (I"ve searched and read). But I'm after recommendations of either people from these forums who work in a shop, or have got this done by one.

I'm looking into getting a r32 auto and swapping with rb25det and manual conversion with the rb25det matched gearbox. Either that or buying a manual rb20det and then doing engine conversion.

Anyone have any recommendations? And also price estimates?

Would I be looking at $5000 ish or $10,000ish ?

This is not including computer or tuning. Just engine and gearbox swap. Also this does not include diff (I'm assuming you need a stronger one if you wanna do bulletproof driveline).

Thanks.

Thanks texas :P

Have you dealt with these guys?

I've also heard of autostyle and unique auto sports but i prefer to give my business to some nice guys who CARE and are enthusiasts.. HOT4s garages (in my mind) seem a bit more into the money side of cars :(

I have had a number of cars done with Fred and Brett and honestly, you'll not find a pair of fairer or more honest people.

Autostyle - I will not comment, just that people here have some strong feelings about them.

UAS are fine but they are not in the conversion field.

For this kind of work, it's best to talk to people who know how to do conversions.

Either way unless you are very careful you may get taken for a ride..

To be honest trying to tackle it yourself is an option compared to some stories and prices I have seen from workshops.. You can fug up a hell of a lot of things, but at least its in your own time and not your money. Many times a workshop will make much the same mistakes as you might, but they'd be charging you for *their* mistakes and research time. Some places would charge you $10,000 for that sort of conversion.

Unless the workshop has definitely done a couple of the exact conversions, can quote you a fairly firm price (based on the other conversions) and you can see the results for yourself.. I'd be just doing it yourself.

As you can tell I don't have much faith in mechanics these days :P

The tricky part is getting the RB25 ECU to work with the R32 instruments and aircon etc.

Not rocket science but you definitely want someone who has done it before and isn't 'experimenting' with your car and money.

That's why I recommend someone who's done it to his own car.

my mechanic can and has done it before we were going to do it to my car but we found an RB26 for a good price.

he does jobs like that in a weekend, drop it off friday night pick up sunday arvo, so its not as hard as it sounds.

PFC wont make it easier weith the wiring because it still has to be the standard loom.

You're best off dropping the engine in if at all possible yourself.. getting everything hooked up.. then calling up an auto-elec familiar with RB's to sort the wiring.

The wiring is the messy part, but any workshop will probably just call in an auto-elec at the end anyhow.

I just got my RB25DET (series 2) and I was hoping you could help me with some questions.

My Skyline is non turbo so it will be a big step with the RB25.

Now then, my first question is about the gearbox mounts, I hear they aren't the same and I will also have problems with the speedo meter. What do you know about this? Can I use the Xmember of the R33 ??

The second is about the harness, everyone that has ever swapped an engine told me that the harness is the most difficult part of the swap. Do you have the diagram of the R32 and the R33 (still can't find it for the R32) and some pointers on how this is done??

Hope to get a reply from you soon

    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
