Maintenance Stuff

Hey guys,

So my engine doesn't feel like it's running the best lately (I made a thread about this a while ago regarding a vacuum leak) as it's a little sluggish pre-4500RPM and is getting 350-420KM to a tank of 98. I read up a little on the T-VIS system so I'm going to investigate that. Now I'm pretty sure there's nothing extremely wrong with it, however I want to go ahead and do a bit of maintenance and servicing to everything I can within reason using my limited skillset/knowledge. So far I've managed to:

- Change spark plugs (exact plug unknown - they were Bosch Quad Sparks though)
- Check Ignition Timing
- Check for vac leaks

What other general/beginner maintenance things can I do to ensure the engine is healthy?

+1 And maybe invest in new genuine Toyota plug leads too 
 
Is your car is a Bathurst?  
If so it will have ACIS.   TVIS is different.
 
Easy to check it's initial operation.
The vacuum actuator on the end of the manifold should pull in when you start the motor, closing the ACIS butterflies. They should open again around 5k rpm.
(If the motor is stopped the actuator opens the ACIS butterflies)
 

Yep just the part where the leads connect too. You can get them from repco for 80 dollars. Just make sure you tell them if your leads clip on or slide on

There are only 2 different types of dist caps used on all 3SG motors, both NA, and turbo.
 
The Toyota part number for your motor should be as in the pic.
 

Genuine Toyota replacements probably fit/work better, especially plug leads.
The cost all depends on where you buy them, and the local the local Toyota dealer would be the most expensive.

I'll get a quote on the price and suss out if it's worth going genuine. Thanks for that mate!

Also I'll order that rotor from Amayama. Is that a third party Toyota parts distributor? (For future reference)

Yes I believe they are independent of the dealers.
 
For genuine Toyota parts it can pay to shop around.
You have to consider shipping, but you could also have a look at Lithia Toyota parts, and Twos'r'us

Wow, worse than I thought.
BTW, Amayama have the genuine plug leads for $101 Aus, ex Sydney so shipping wouldn't be much

Is $100 reasonable for a set of genuine plug leads? Cause I was wondering if there's any downsides to going aftermarket instead (not that I know of any - I saw on Twos'r'us that the STI plugs are decent)

Got my quote back, don't think I'll be ordering genuine parts from Toyota haha

Bet I can beat that :D
 
EDIT: $101.82 for the cap, $129.62 for the leads (Amayama FTW!)

$100 for the cap?? Fair enough it's a genuine part but is it really that much better over a $30 Bosch one from SCA?

^^ I would be willing to bet the odd sca would know plenty about mr2s, just gotta find the right one ;-)
