PROBLEM FIXED...for all those wondering timing belt jumped 4 teeth!!!!!!!!!!!!!.....yes i know i dont believe it either...but sure enough we took it apart and bam it was all out...put it back together and she is beautiful!!!!!!!!!!!!!!!1

hi guys

ive got an rb20det r32

it was non turbo auto and is now manual turbo...

everything was going fine...would fry the tyres without any trouble at all!

one day i was driving along and hit a massive bump in the road...

ever since the car has completely changed

its started to miss straight away.....throughout the whole rev range

idle is absolutely disgusting...just missing and rough as...and the worse problem is the car has 0! power....a charade would flog the pants off me...it drives and sounds EXACTLY like and naturally aspirated rb20..deep and throaty sound

BUT ALSO pings like nothing else from about 4k onwards

list of things we have tried

changed cas

changed ignitor

changed coilpacks

changed knock sensor

changed o2 sensor

changed ecu

changed afm

changed plugs

wiggled all wires on the car and it made not difference

inspected turbo

pulled exhaust off

tested fuel pressure

checked boost pressure is running 8psi which it should be

now a couple of weird things!

i retarded the timing as far a it could go...this stopped the pinging a little bit...and allowed the car to rev smoothly...but still is the slowest rb20det on this planet

the only thing we can think of now is that the timing belt jumped a tooth or something ridiculous

does anybody know anything else to try

symptoms again are

VERY slow

pinging

missing

very rough idle

sounds like an NA rb20

car is quieter now to i might add

Hi...

where did you say that 'bump' in the road was??....I need my car to be a bit quieter!!! :teehee:

anyway, hope you find a result!!

NA engines usually have a higher compression than turbo engines, id say get it looked at by a mechanic, it wouldnt hurt to have a compression and/or leakdown done on it at least this may give a little comfort as well.

Also there is a couple of things you could check, intercoolet piping and joiners.

Good luck with it

Hi DA21 !!

I'd like to know more about your car (if that's ok?)!!...sounds hot and interesting!!!

Superspit!

I'm having a similar problem, I checked the ecu codes and got #11, and #21, crank sensor, and ign. circuit. My engine is a RB20DE conversion to DET and my problem started very similar to yours. Check to see if you have any fouled plugs, my #6 cylinder is not firing at all although the coils and plugs, etc. are fine.

If it cracks between two pistons u wont lose any water or oil it will just have bad compression , u have tried just about every other problem just other thing to look at

Hello,

Just a few suggestions..might have been covered but hope I can be of some help

No noise from the fuel pump.?...could be on the way out.

Fuel filter could be blocked....how does she run at idol?

Could one of your injectors be cracked or become faulty after the knock?

if you have checked these...take it down to a workshop.

Cheers Tekin

hi guys keep the comments coming.....

ok possible it could be blown head gasket...might be somethign to look at last id say

fuel pump is making normal noises...fuel pressure was pretty good!

injectors...very likely i would say...its definatly possible some are clogged

what do people think regarding a timing belt jump???

    • If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.
    • Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)  
    • Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...
    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
