    Difference in knock sensors

    There are three part numbers for a 89+ 7M-GTE MA70 knock sensor: 89615‑30020 08/1988 to 08/1991 89615‑33010 08/1991 onwards (supplied by MATUSITA) 89615‑33020 08/1991 onwards (supplied by NIPPONDENSO) Both of the 1991 onwards sensors have been replaced by another number...

    Best solution for new rear bumper?

    My 89 (widebody) MA71 came with a pre-89 (narrowbody) rear bumper when I bought it, so it doesn't fit properly. What's the best option to replace this? Are new OEM bumpers cheap enough from Toyota or is it more cost efficient to get something second hand? Are there any alternatives like...

    Tips on transmission removal?

    Does anyone have tips on removing the transmission by itself? (Auto a340, 7M-GTE) I've only ever removed it whilst pulling the whole engine, and wasn't sure if there's anything specific I should watch for whilst dropping only the transmission. Thanks

    Suspension options

    Hi Aussie people, What are my options for some new suspension? Are the brands of coilover available locally decent or should I look at importing some Japanese / US made brand? The car is just for street use - on our nasty roads - so I need something stiff but hopefully not too stiff that...

    Okay I'm SICK of my code 52. PLEASE help me fix it.

    OK, So I had a code 52 for a while... I did the knock-sensor rewire since I figured my wires were shot. The code 52 disappeared for a while and the car was running nice. ...It's now come back. It's intermittent. I can't _make_ the car get a code 52 by revving hard or boosting lots, but...

    Rocking Shocking Knocking

    Hi :) To set the scene, my car's suspension is, well.. useless. Every single bump makes the whole car jolt, creak and rattle. Now, I thought I'd fixed a code 52 knock sensor problem by re-wiring the little bastards. However the code 52 is now returning. I'm 98% sure the wiring is perfect...

    Front fender removal

    (Yes I searched :D) Can someone give me a quick run down of what's required to remove the front fenders? Mostly I just want to know if there's any hidden bolts that are a trap for first timers, or anything similar. Thanks :)

    Can I use a 4 wire oxygen sensor

    As the title says, can I use a 4 wire oxygen sensor instead of the stock 3 wire? The difference, as I understand it, is that the fourth wire is a dedicated signal ground. On the three wire, the exhaust system is the ground, right? So can I use a four wire sensor and ground the signal...

    HKS SSQV Squeaking :(

    Hi all, Recently installed a SSQV kit on my 7M but the blow off valve 'squeaks' as it lets out low boost pressure (less than 5 psi)... is this normal? can I fix it? Do I just need to adjust the internal springs of the BOV? HKS don't give any instructions on what can be changed/adjusted on...

    Steering 'wobble'

    Hi all, Had a quick search around for steering threads but didn't come up with much. What parts can generally wear out in the front end of a MKIII that would cause 'wobbly' steering? The front wheels feel 'wobbly' compared to the steering wheel. Any slight bump in the road will cause the...

    Laggy auto transmission

    Hi again :) - I searched around but couldn't find much relevant info on my AT problem (plus I wanted my own thread! :D) Anyway... Accelerating from stand still my car is very.. nonlinear. As I press the accelerator smoothly, sometimes (not always) the car will rev to around 1900rpm before...

    Central Locking

    Well how about that... not one thread on SM mentioning central locking. Just great, because mine is broke. It's been broken since I got the car but now I want it to work! :) I see there's a few tests I can do from the TSRM, testing each wire coming into the central locking box in the...

    Can a CPS output be dependent on temperature?

    Still trying to chase down some problems (misfiring when idle and very hard to start when it's cold)... I'm considering the CPS as the main culprit. If the CPS was faulty in some way, that would explain the misfiring at low RPM and running nicely at 2000+ RPM, but would it completely explain...

    Fuel upgrades

    I was just about to change my stock fuel filter, but considering how much of a pain it is (I can't fit my hands in there to get to it! :(), I'm going to upgrade to a new fuel pump (bosch 040) at the same time. Got me thinking... is it worth relocating the stock filter so its easier to get to...

    HKS SSQV part numbers for MA70

    Hi all, I had no idea where to post this, so apologies if it is in the wrong section. The "kit" that HKS sells with their SSQV blow off valve... does this come with the upper intercooler pipe with built-in flange or is that something people like suprasport.com have developed themselves...

    WHY does the targa leak?

    Hi all, I have read all the posts on SM and all the SOGI tips about targa leaks, but i still can't actually work out why/how they leak. Mine leaks from the front two corners of the targa, where it meets the car body. As far as I can tell, the water either pools up in the lower, plastic...

    I need to pick between Maftpro and standalone

    Okay, so I'm still new to the whole car mechanics/tuning/modding thing... and now I'm stuck. :) I've rebuilt the 7M in my daily driver after BHG, with a metal head gasket, ARP head studs, ARP conrod bolts, new semi-forged pistons, bearings, machined head, crank, rods, etc. I've been planning...

    Code 24 common resolutions?

    Another question :) Car's throwing a code12 + code24... I'll look into code12 soon, but just wondering if there's any "common" causes for code24 before I follow every test in the TSRM? Thanks!
