hey all

i am going to drop a RB25DET into my R32 GTS4

i guess i have to put a R33 RB25DET ecu and loom in but,

(i know this may sound stupid) will the RB25DET engine bolt up to the GTS4 gearbox?

also with the wiring loom, will everything connect up?

is it a straight forward engine swap?

any info would be sweet

thanks

chris

Not sure about the R32, but i assume it would be the same as the R33.

It is not just a straight swap. Since the GTS4 has front wheels that also drive, the oil sump is a different shape in the GTS4's RB25DE. This means that only another RB25DE from a GTS4 or an RB26 will do. You can turbo your DE, but I agree, an engine swap would be better. Bit of mucking around, but good luck. :)

You can get a RB25DET that will drop straight in from a Stagea. I'm not 100% sure, but I think they made some turbo 4 wheel drive Stagea's, but they are very rare.

Not too sure on the rest of the details. I think there may be more to it than just the oil sump anyway. Might have to wait for one of the experts to answer. :)

I've got an R33 GTS and I'm doing the same swap. I don't have the all wheel drive issue though, so I'm not sure on all the details.

would it be easier to convert my R32 GTS4 to RB26DETT than a RB25DET?

plus would i really need a complete 4WD stagea front cut to complete a RB25DET conversion to a R32 GTS4?

what parts are needed out of the front cut?

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

      Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P
