-wouldnt a front diff and a rb25 single turbo give it away faily easy ?

I don't know how you'd spot the front diff on the road seeing as its nestled nicely in the oil sum under the engine.

Things to look for would be 4 wheels spinning when taking off and the torque split in the cluster. R33 GTS4's are all N/A and R32 GTS4's were all turbo. I guess to a certain extent if you check out the wear on the wheels of a GTS4 it should be more evenly worn (theoretically that is, ATTESA however isn't fulltime AWD though) also compared to a GTSt, GTS4's tend not to oversteer as much.

oh you mean out on the street driving , not inspection. as in mock ups etc !

i could be a smarty and say not 4 wheels spinning on take off but a combo of 2 rear and 1 front alternating but as you can see i didnt even get the engine right ... :) so i will shut up and say thanks.... i leaned something

If you destroy a motor in a GTS-4, do you have to replace it with another motor from a GTS-4?

its easier and cheaper to... noone has a use for AWD RB20DET's :P as they only fit AWD R32's, A31's and C33's. If its just a damaged head you can replace it with a GTSt head. I think the block might need modification to fit. Oil sump and front diff need to be swapped for sure, or you could use a GTR one (grab one off someone who's putting an RB26DETT into a RWD car for cheap).

I believe you just have to pull the 4WD fuse out on the R32s.

or wire up a switch to the fuse and have a "slide beyotch/grip beyotch" toggle switch in the cabin :P

So you reckon GTS-4 motors are cheaper than normal RB20's?

should be. I mean, if you had a R32 GTS4 wreck and no one wanted to buy the engine, you'd sell it cheaper so someone took it right? Cars that AWD RB20DE's feature in, in general are rustheaps (as most of them were used in snowy areas in japan... hence the need for AWD) so its not like there's any shortage of spare engines.

And if you can't find an RB20DET, then put an RB26DETT in, or an RB25DET out of a stagea (which is pretty tricky, but doable).

Is it easy to turn the front wheels off?

You can also just flick the ingition off and on while rolling (faster than 5km or so). disable the ABS and 4wd (same as fuse)

Then its the same as a front heavy gtst...

Don't get me wrong... its not easy, an RB26DETT swap is easier I reckon.
RB25DET simply bolts straight in. And everything mechanical connects up. At least you don't need a new exhaust and intake setup.

Either engine, you need to re-loom and re-ECU it.

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • 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.
