Good write up for installing the swaybar here

No need to replace the endlinks if the factory ones aren't completely stuffed.

The car went away a couple of weeks ago. Another summer gone! I did not end up getting the spark plugs/wires replaced. I have been working lots more than I thought I would this year and plan on having this stable job all winter now, so spring is looking promising for the GT-Four! I will install the sway bar over winter/ spring, and I am lining up BC coilovers, possible strut bars, and the Cusco underbody brace through Klue. I'm hoping to have some serious handling improvements, and then I'll be looking into more power either late next year or the year after, depending on funds :)

I already have a turbo back exhaust, and a shitty manual boost controller. I'm looking for peoples opinions on what the best bolt-on, bang for buck performance parts will be? I am still technically a student, and have been saving a bit for a house so spending an extra $5k is out of the question in the short term, anyways. With~$2000 going into suspension next year, I would probably be looking to spend a max of another $1000-$1500 on some power in the next 2 years as well if I can..

I've been thinking a ct20B/ct27 and proper boost controller will be very beneficial.. Thoughts? Maybe a ROM tune from ATS would be very cost effective after? :shrug: Getting a proper cold air intake has sounded like a bit of work (battery relocation etc) so I've held off for now, but maybe I should start looking seriously into this?

On top of this, I have been looking into all possible preventative maintenance I can/should do now that the timing belt has been done. I've come to realize that there has been very little maintenance done to the car by the previous owner, and possibly ever! At close to 22 years old, I don't want to miss anything and have problems in the long term because of unnecessary negligence.
I did the timing belt this fall, and I still want to have the plugs/wires replaced (possibly by me if I'm feeling adventurous this winter!). Are there any other worthwhile maintenance jobs worth looking into? I've read about getting the valves serviced but mine don't seem to be an issue atm. They are not very loud or anything like that so I've been holding off, although I'm not positive what to expect if they are due for a tune-up..

I'll state again that I am by no means experienced when it comes to working on cars, and I am too nervous to work on this car because I love it so much, and want things done right. I've done little things to Honda Civics, and other rust buckets that I care very little about. The biggest job I have done to the Celica by myself was installing the mid-pipe and cat-back haha! I tend to gather as much info as I can, and then hand it off to the licensed mechanics most of the time so I can trust its been done with proper tools etc.

I look forward to gathering more info and hearing any tips and opinions on where I should go with my budget-oriented build :D

I have all winter to weigh my options, so feel free to chime in with your experiences and convince me to buy your parts! :twisted:

The stock intake is technically a cold air intake, but if you want to switch to a cone filter or build a straight intake you can buy a smaller battery and move the battery to where the airbox is, I've seen that done several times around here.

True, I have read about the tubing bringing in cold air. You're right, I was thinking more of a big cone intake, possibly with that cold air piping still in place, keeping functionality of that part..

I have seen a few of the DIY threads on these intakes as well, but I haven't gotten around to really planning it out. I doubt people see any significant gains with this though? I've read that if done wrong, sucking in hot air would actually negatively affect performance. Would it be more about induction sound for most people?? Just curious :D

The straight air intake on my car made a very noticable improvement in performance. Then I removed the AFM - that was a massive improvement. Also, induction noise is very audible now at low RPM and neg boost. (stock turbo)

I highly recommend a straight intake. The OEM intake is convoluted and at one point, it is constricted down to a cross sectional area of ~2x1.5" as air is pulled in from behind the headlight. There is also a large, useless resonator box in the front left fender designed to reduce noise.

For my setup I decided to use a smaller battery and relocated it to the old airbox location like underscore described.

I just tossed on a Vibrant adapter and a cone filter, it can add a lot of induction noise, on my car particularly when I'm hanging right near neutral boost. I think the hot air issue is more prevalent on NA cars but don't quote me on that.

Alright! That will be a definite buy over winter. It is a relatively cheap upgrade, and I see how it could make a big difference, especially with my exhaust being opened up now!

Corey, how did you get the AFM out? It's needed if you have the stock ECU right? I would love to get that AFM out as well haha

That's how I'll keep it cheap!

TO ditch the AFM you need to swap to a standalone or Gen 3+ electronics. If your car is running well and you're not planning on a big build there's not much point in removing it.

I went with the Gen III EFI. I purchased the required parts from www.mr2oc.com

Sometimes the members there put together gen III kits from MR2 part outs. I'm running a gen III mr2 ecu in my car with 205 injectors.

Of all the money I've spent on my car, I think the 500-700$ I spent on this EFI upgrade was the best. My car always had AFM issues and it soon developed a starting issue. The moment I switched to Gen III EFI, all problems disappeared. Now running 17-18 lbs of boost on a stock turbo.

Cheers

Good to know! If ever I have issues with mine I will know to just invest in the gen3 components as opposed to putting money into a new AFM..

I haven't had any problems as of yet!

Little update, I got my hood scoop and vents re-painted! They were not painted when the rest of the car was about 3 years ago.

Added a special touch to match my general colour theme and I'm pretty happy with the result!

Car is away for winter. Just leaving little updates for my own historical purposes I guess.

Went away early October after an inspection at Toyota found coolant/oil leaking around my timing belt cover. I had noticed it once before, and was told it was excess from the previous bad seals etc.

Timing belt was done by a shop I thought I could trust about 2 years ago, but it sounds like I get to pay to do it again. :cry:

So much for coilovers/upgrades this spring! :bangshead:

Well, car is out!

rsz_1dsc_1038_noplate.jpg


Timing belt job was done on May 4th, 2016. Replaced the pump, belt, tensioner, and every seal possible! Also had my valve cover gasket replaced. The tensioner was getting loose which was what I could hear a bit, and the water pump was leaking, as well as a seal or two (don't remember which ones). The last shop to do BOTH of these jobs had not replaced the faulty tensioner (and didn't tell me about it), as well as not properly sealing the valve cover gasket and various gaskets under the timing belt cover. they also stripped one bolt terribly and left it which caused some headaches for the Toyota mechanics. Needless to say the last shop will be getting negative feedback from me, if I can hold back from burning the shop down :shoots:

I find it a little bit noisier than it was now at startup, however it seems to be running great after warming up! The Toyota guys recommended Mobil-1 synthetic 5W30 which was different than what I've used in the past.

The timing belt job was done at Toyota for a painful price, but I can rest assured that the two year warranty will cover any potential issues in the near future. 2 year/ 40'000km warranty on their service jobs!


Overall the car is running well again! Can't wait to start saving for something other than maintenance xD
