Potentially Terrible Idea

now i'm not sure whether i'm looking for advice on a "how to" basis, or just someone to tell me that this is a dumb idea and to walk away, but here's the thing

i own ONE car. 1996 r33 gts. rb25de etc. you all know the drill

when i first bought it i had a bit of extra cash lying around and managed to score a big ass intercooler and 2 garrett turbos for a matter of a couple hundred bucks.

basically, all this is leading to one question

what kind of work/how much money will it take to make a functional and RELIABLE rb25dett??

i've been told everything from "bolt it all on and away you go" to "you're going to have to replace every mechanical part of your car"

is there a simple way of doing this or have i dug myself a hole that i should just fill in and enjoy my naturally aspirated goodness?

if anybody could shed some light on this for me i'd greatly appreciate it because i have this horrible feeling that i'm in waaaaay too deep

it's not just a matter of going out and buying a gtr or gts-t any more. it's come down to wondering if it can be done without spending more money than just buying a new car. don't get me wrong, i'm not just trying for the ebay special, if something needs genuine good quality parts or professional work done i'll go there, but it's also my daily driver. i don't want it to be off the road for more than a weekend at a time.

the things i figure i'll need to do so far are as follows:

aquire remaining parts required ie. intake/exhaust manifolds, dump pipes, cooler piping, oil lines, etc.

upgrade fuel pump

upgrade injectors

possibly upgrade diff, gearbox, clutch

possible engine rebuild and have head worked/decompressed/whatever

have i missed anyhing? anything there not required?

can somebody giz a hand here?

from the little bits of info I'm come to know, here are somethings you might want to consider.

Factory injectors and fuel pumps run out of juice around 210-230rwkw so you can have 4 truck sized turbos hanging off the side and you still won't make anymore than 230rwkw.

I'm thinking the exhaust manifold will have to be replaced with custom ones to fit the two two turbos.

New twin dump pipes will have to be either purchased or replaced.

Twin air flow meter

Aftermarket engine management

Inside the engine, I've heard you will have to change the pistons, something to do with the change in compression. Will also have to change the gasket as wel.

Pretty sure I'm missing a few things

Injectors - $900

Fuel pump- $200

twin afm - $500

exhaust manifold - beats me, anywhere between $400-$1000 I guess

Power FC- $1500

New pistons, conrod etc etc - dunno a few grand or

gasket - don't have a clue

a tune - $500

Dump pipes - $x00

well, thats as much as I know.

did you guys also notice that its a de... compression, smaller injectors and ECU then RB25dets. Sell the motor and buy a RB25det with ECU. There is a thread in the N/A section about putting turbos on de's, its really not worth it!! when you can get a det motor and put that in. Besides then your engine plate wont line up with whats really in the car, sell it and buy a GTST or GTR!!

Sell the car and buy a turbo model, you will have a much better base to begin with.

de box = rubbish.

de diff = rubbish.

de brakes = rubbish.

by the time you've brought those up to scratch with a stock gtst you've spent 3k plus labour without even looking at the engine.

Just grab all the pieces from a gtst and install them onto your car - go single turbo. Install a spacer/swap pistons, larger injectors, ecu. Valve springs might be a little soft for big boost.

      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.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      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.
