I think this is a good lesson for people getting engines, be it from a JDM source or even a junk yard or other USDM motor. One thing that I think should always be done while it's still sitting on the shipping palate and hopefully still has a trans on it. Hook up power to the starter and do a compres...

Why not just fix or replace your IACV?
Seems like a ton of work to add more crap to your engine bay to do a job the motor used to do automatically.

You don't need a standalone. It should run just fine on the stock ECU. It's been done before.
I am running a full turbo blacktop on my GZE ECU as well and it runs great.

It has as much to do with torque as it does butterflies.

My All-Trac's starter is under the intake manifold, for its E series gearbox. So the GZE MR2's starter is under the exhaust side? Seems odd that it would be since they also have an E series. Edit: never mind, I'm not thinking about the GZE's stock SC/intake setup. I suppose all that space is taken ...

The reduction type starter is quite a bit smaller than the conventional starter. I have this type on both my GZE and 4A-GE on the exhaust side. (Both engines out of an AE92 chassis) Thats probably what my BT has too. Can you take some pics from straight on of it mounted on the engine for me so I ca...

So I just got two exhaust side starters in. They will be used on my engine dyno with my RWD bellhousing and will work fine. Unfortunately I tried to squeeze one in next to my production turbo mani and they occupy quite a bit of the same space. These both have the massive solenoid like my old GZE sta...

Awesome, now this is going to be some left field crap. I lost ONE cam cap. Can a 4AC one be used on a 4AGE? I don't know about interchangabilty so I can't speak on that, however I can tell you that things like cam caps are really motor specific, as in the particular motor i was machined for. It's p...

I One thing I did discover is this, see pics. Basically my heater pipe (I am running a BT 20v in an AE86) is touching the knock sensor I highly doubt that is any issue. Your knock sensor is designed to detect a very specific frequency and a very high frequency. I would suspect any vibration transla...

I dont think any of that was negative feedback. For example "your oil sucks." 86 and 240sx owners are notorious for being on the cheap which I why I think everyone in this thread is suggesting easy/cheap alternatives such as GM supercharger oil (Im a cheap ass, I run GM sc oil too) GM sup...

Sorry for the delay. I missed this post.
What exactly are you referring to? Do you want info on how to remove the old bearing and install the new one? Or are you talking bigger or different than that?

I'm very confused. I try to offer a better solution at the same price you can find the other preferred alternatives and yet I get nothing but negative feedback. I talk to Ogura, the manufacturer of our superchargers and they tell me that oil selection is extremely important for the longevity of thei...

I have flanges available now if you ever want to upgrade to anything a little prettier hehe. I can also fab manis, change out flanges and stuff for anyone who isn't able to. http://matrixgarage.com/store/4age-fabrication-supplies It's hard to tell without knowing how stiff they went in there but I w...

Could it possibly be the vvt pulley sticking in the on position? Even though the ecu is turning it off for some reason the pulley is staying on. I find it pretty unlikely but I would try a run with it unplugged just to eliminate the possibility. I don't know the internals of the VVT well enough but...

I now have replacement bearings for the largeport SC12 pulley. Completed a rebuild on my first pulley today. https://sphotos-b.xx.fbcdn.net/hphotos-ash3/625501_514140085288888_1735741209_n.jpg https://sphotos-a.xx.fbcdn.net/hphotos-ash3/545993_514140081955555_817356219_n.jpg https://sphotos-a.xx.fbc...

That would be my suggestion as well. The performance is hard to beat and at the price they are even harder to beat. http://www.matrixgarage.com/products/tomei-143056-poncam-camshafts-toyota-4ag-264-81mm-int-264-81mm-ex You will see good gains without gears but if you get gears and put it on the dyno...

Well since you want the VVT off above 6k or so you could just unplug it. If it idles normal you know it's disengaged and should remain so in the upper RPM. Honestly the best thing would be to get it back on the dyno and do a run with the VVT unplugged and then one with it wired constant on. I belive...

ran across this on another forum but it was just one person noting that the injectors are side feed like the 20v but flow more. The motor is a 2TZ-FZE. I found pics of the injectors and they are side feed like the 20v but i cant find anything on the flow rates let alone anybody even using them on a...

Since this is a MAP motor something that effects VE will effect AFR. Your VVT should switch off around 6k. If the VVT doesn't switch off it will cause a power dip due to a reduction in VE. That reduction in VE will also cause it to run richer and could cause more of a power dip. That's still where m...

Unfortunately I got an irritated phone call from her yesterday although I can't say I was surprised. In fact I was quite surprised she suggested people could contact her with concerns. Apparently her true intention did not come across clear in that original phone call. The more I think about it the ...

The back cover bearings are 46mm. If we can't get the pulley side bearings but can get gearbox side bearings the next best option may just be to machine the pulley side from 45mm to 46 mm and machine it deeper to accept the wider bearings. Adding depth to the journal with the pulley on it should be ...

I just had my SC12 taken apart to replace the seals and the case bearing fell apart! Any further development on replacements? It is not looking good. Very few manufacturers even have 17mm ID cylindrical bearings so I am struggling to find one oversized or undersized that would work with modificatio...

I have recently added an online store to my website. Being in the MR2 comunity I knew a lot of things I wanted to add just based around my likes and knowing the 4AGE and AW11. I have access to a ton of products though, both universal and vehicle specific. Right now I have very low overhead so I can ...

You might gain a little but I doubt more than 5 or 10. I suspect something else is wrong. The fact that the VVT causes a bog is a good sign but it doesn't tell you that the whole circuit is functioning or that the ECU is triggering it. Ideally you would want to dyno it with and without as I posted a...

Any cel's? What's the idle rpm when you say, "too high," and after also after it drops? It's normal for the idle to be higher on a cold start; the idle will drop when the engine gets up to operating temp - the iscv controls this function. Definitely check the thermostat to make sure it's ...

By rollers I assume you mean chassis dyno. If so how did you determine your FWHP?

My point and it should have been made clear above is that just because it says supercharger oil does not mean it's all the same or all compatible.

I should specify that I can now get clutch bearings for the older larger SC12 pulley that was in the US GZE. I am looking into getting bearings for the smaller SP GZE clutch witch is a different size. If anyone has a SC14 and can get me a number off the bearing and or dimensions of the bearing I can...

So I can now get replacement bearings for SC clutches and I can replace the bearings as a rebuild service. Unfortunately looking at the two clutches I have I am thinking that is a very small part of the problem. I went turbo when my SC died. The clutch bearing is what failed and it completely disint...
