As much as I love the rb20dets maybe it's time to just pull the old girl out and source another one or even upgrade to a 25 while your at it? Gotta remember these motors are getting old now a days and could just be old age that's gotten to the inside maybe ?Running issues are intermittently happening still.
So.....
Changed out my fuel rail, reg and injectors from my rb30det (hardware i know works) along with the power fc, loaded an rb20det tune along with all the injector corrections to suit.
Drove around all good, drove it work for night shift (27km trip) and it was perfect, afrs where imo spot on the money, drove really nice, crispy performance.
Then drove home at around 2am, nice cool air about 22' and got about 2 min up the road, solid off scale rich, coughing and sputtering its so rich, all the way home.
So i think, only hardware left is the harness, the rest i know works perfectly in my other car, so i strip the harness looking for a short in the injector signal wires
(thinking they're being held open via a ground short circuit, rub through wire)
And i found nothing but a surprisingly good cond harness.
Fml!
Separately wrapped up the inj signal wires, tapped the harness back up, no change obviously!
So put all the stock hardware back in.
Still rich af at idle, (it stalls/fouls plugs if left idling to long)
Ran a new afm harness back to the ecu today, along with different afm.
Ill test drive tomorrow.
Thing has me stumped......
-
New afm would be your best first choice

Good to see you got it sorted man! Time for a nistune and a mild tune to get the rest of it running perfect ?So I think I may have fixed it?
Between both sets of injectors, my old set from my 25de and the set out of it, ive found 3 dead injectors in total.
So I measured them all for impedance, basket cleanliness, and set them up and ran them with the old cas spin method to trick the ecu into cycling them, 2 would do nothing and 1 would only work 50% of the time, and 2 of the 3 had high resistance,
So I picked 6 that tested up and functioned ok.
Put them in and it started and idled perfect straight away.
Set the base idle and then base timing to 20',
Took for a drive and feels like stock standard again, happy days!
Afrs are not as tidy as id expect for a factory tune, but good enough to drive properly.
They're atleast steady, close to what id target and not crazy rich/lean like it was.

I had a 25de Neo in my old 33 and I turbod it on my green p's. All I did was source out all the stock parts so, side mount inter cooler, stock 25 turbo, as much of the stock piping as I could get and that was it. I already had the det ecu but you will need that aswell. In total I think everything cost me $300 but I also paid a mechanic friend to install it because I didn't want the hassle of tapping holes for the oil lines etc

If I had the funds I'd stick a 26 or a 2j in it hahah.i wanted more power too, so i stuck an rb26 in mine lol. its about to get a LOT more power
but with the rb20 150kw was good for a daily, plus it had over 200,000kms by the time i pulled it out & never missed a beat. i was happy for the compromise with my uses.
next il be rebuilding it to put into a cefiro i picked up, so we'll see what numbers it can make then
I get one crowd telling me I should of made 180kw and then another mob telling me 150 is normal, I'm not too fussed as i think it goes pretty decent for 150 but I would of been stoked to get 180 out of it
-
Hahahahaha preach it brotherIts always an issue, want more power, get more power... then when you get used to it you instantly want more power... had my 32 running 220kw on 14psi for over a year on low boost... its responsive but all i want is mooooooooooooorrrreeeee pppoooowwwweeeerrrr
but I'll be more than happy to stay at a 200+kW level man, 150 just isn't doing it for me
-
I'm not 100% certain dude, I'll be going back to him Monday so I can ask him then but I guess for now it just makes what it makes.What were the mixtures? What was the timing at peak power? IAT? Other factors?
Would definitely love more power but

Cheers man, I was considering going a 25 but I wanted to give the 20 a run and yeah man they love the revsLooks great mate, love the GTR bar, on the mods i guess it depends what you want in the end, best to figure out what your gonna spend and how you gonna drive it, an RB30 or 25neo with 3076 is what im into due to torque.. but i hear RB20's love the revs so that sounds fun too , at 220kw's im sure it'll be fun either way
Hmm okay bro, I've been told it's a good figure then I have other people telling me they were hitting 180kw so I was just a bit curious. I won't deny 150kw is awesome but I want moaaar power!150kw isn't a bad figure at all, i was getting 145kw with an old rb20 & standard rb20 turbo on 14-15psi with an upgraded fuel pump & splitfire coils, it's pretty fun to drive even at this power level hey
-
My tuner predicted about 170-180 and we were both shocked when it wouldn't go past 150... Anything simple that could be holding it back ?
-
Okay cheers guys, much appreciated
-
Stock is like 132kw isn't it? I'm not familiar with rb20s and what power they should be making so thought I'd seek some wisdom here
-
Hi guys, so I recently got an adaptronic e420c installed and tuned in my 32 (rb20det) but we only made 150rwkw at 14psi.
Basically stock Apart from fmic, 25 turbo and full exhaust system and bigger fuel pump.
I was just wondering is that relatively a normal power to see with such mods as I was talking to another bloke who was running the same set up except aftermarket coilpacks and made 207rwkw
Cheers in advance
-
Thanks man! Yeah I spoke to some of the older and wiser boys and they said they love the 20s so I thought bugger it I'll give it a go!Just read the thread up until now man, keep it up!
Really keen to see where this goes tbh
I'm keen due to the fact that no one gives the 'ol 20DET any love, it would be awesome to see someone make a mental 20DET
So, I'll be following and watching this thread intently, don't let us down!
Unfortunately progress will be a bit slow over the next couple of weeks/months due to loss of job and having a hard time finding one where I live.
The day it got tuned another 20det was on the dyno before hand and made 200kw and I was extremely impressed with how it went afterwards so my goals are roughly 220-250kw
Update: did some tidying up in the interior, the centre console area was a bit dull and had paint chips everywhere so I painted it again and was impressed with how it turned out. Will get some photos up soon.
If anyone can point me in the right direction for good mods to suite the rb20det I'd appreciate it!
-
Thanks mate! Yeah I've always been one to have a car that stands outNice car!!!
That colour looks awesome!!
-
-
So after a long long wait the car is finally back and it's so awesome!
So what's been done since its been back?
Well basically the car had to be completely rewired due to it just being completely crap and causing a lot of problems.
Adaptronic e420c has been installed and tuned!
Okay so with a stock 25 turbo on a rb20det running at 14psi we got 150kwrw. At first I was a little dissapointed it didn't make more but upon driving it I realised 150kw isn't too bad, in fact I was extremely happy with how responsive, snappy and quick it is.
That's the update for now
Next to come is bigger turbo and gtr injectors (if you have anything for sale please let me know).

Absolutely loved reading this man! Will be checking regularly for updates.

cheers mate, hopefully some big things to come in the next couple of weeks/monthsNice 32 mate. Im looking forward to where this heads. Best of luck.

Hi guys, thought I'd share my progress with my newly acquired 93 r32 gtst.
A bit of back story of myself and the new car.
So before hand I owned an R33 pig, which was running a 25det Neo under the hood.
But I got sick of the car as it was never running properly and was always spending my money fixing it rather then upgrading it so I decided to sell it and a mechanic friend hooked me up with his 32 shell.
Quick back story on the 32. The previous owner before myself and my mate, was running a 26 motor with power figures around the 350kw+ so once upon a time this was a weapon of a car.
Since I bought it I slapped in just a rb20det, always heard good and bad things about them so I thought hell why not give it a go.
And once i had it in and running it was amazing.
Now the starting mods is basically all stock. I did pick up a hi flow 25 turbo but after a couple of drives noticed heavy white smoke, got it up on the hoist and we realised the rear seal was screwed.. So we smacked on a normal 25 turbo.
After a couple more days I noticed the car was chewing fuel at an extreme rate and blowing black smoke and by extreme rate I mean using a quarter of a tank without driving more than 20-30kms. Granted it does have a huge fuel pump in it (can't remember the specific one as I'm having a brain fart) but the car has been at my mates performance shop waiting to be touched.
So now your up to date I'll fill you in with what's going on at this specific moment.
(21.1.16) have purchased a e420c adaptronic ecu (haven't really found much I denationaliser on these besides a lot of people are running them in their skylines so if you could tell me what you would rate it that would be mint) but u fortunately 2 days ago I received a phone call of my mechanic informing me that the yard was broken Into and a whole bunch f stuff was missing from my engine bay, a set back none the less but atleast it makes me replace some parts with better parts.
Other than that your up too speed, I wish I could have given you more for the first post but I haven't really been doing much too he car besides just the general stuff.
Future plans for the next couple of months.
- gtr injectors and resistor pack (if your selling them message me)
- 3076 turbo or something that will make 250kw comfortably with good response (if you have any recommendations I'm all ears)
- FFP (I'm not too sure about this one, if you have advice in happy to take it)
- my goal for the 20det is to make 250kw or something close to this.
- catch can etc
Car currently has
- 3.5" exhaust from dump (will be going 3")
- fmic
- 455 walbro fuel pump (I could be wrong as I cannot remember exactly, will update once I double check)
- kakimoto wheels
- new coil overs all round (brain fart can't remember the brand, it's a super hot day here)
- gtr front bar and bonnet
This is the car currently as it sits, I will get some more photos when I see the car next.
-
Really good read mate, enjoyed it a lot and gave me some really good ideas for the future.
I'm curious, have you ever thought about putting in a 20det or 25det ?
-
Thanks dude, I had a feeling it might be the afm so I'll go sort out a z32. I appreciate the feedbackSounds like your AFM has dry joint inside it then. Cut it open and solder the pins first, there is a how to on here somewhere.
A new Z32 AFM and a tune would likely fix it too.
-
Will go give it a try, thanks mateAnd if you've got standard air box just remove the hose between the afm and the box so it doesn't suck any leaves and shit the might be in the bottom of your air box
-
Have turned boost back to normal but is still having issuesTurn you boost down, colder weather means denser air. More "air" read by the AFM means a higher TP Load, and because it's a stock ECU and tune you're hitting cells where timing is absolutely retarded as fk.
Boost doesn't equal TP Load, you might be able to run 10/11 psi in summer or so but when it's cold you'll hit those cells running the same boost.
I suggest you turn down the boost.

Everything is back to stock, was just driving home from the gym and it seems once the turbo spools up to a certain point and I off the accelerator it just stops working.
Plugs were gapped correctly and I'm under the impression I'll need to go for a tune, was just seeing if anyone has any ideas. I'm very new to the forced induction life, lesrn from
Your mistakes I guess.
Cheers guys
but I'll be more than happy to stay at a 200+kW level man, 150 just isn't doing it for me
