1987 Toyota Corolla GT-S w/ AE111 20V 4AGE Blacktop

UPDATE:

Hello everyone. Here is an update on the car and engine since I have gotten it to run properly. First off the clutch was replaced. Prior to the replacement it was AISEN OEM like. Now I have NKK stage 1. I believe this is a better alternative to Exedy's clutch disks. If someone can confirm this, it would be great for others looking for an alternative. Thanks in advance. It is great for daily, grabs hard when I need it too. Pedal isn't stiff and won't give you hulk foot. On my previous car I had ACT, although good performance wise, it wasn't good on my leg in 1-2hour traffic. I am running 1NZFE Cops on stock ECU and harness. Please refer to the DLI thread on Club4ag's 20v forum if you are interested in an alternative way to run the engine without the distributor cap and wires. The SP-TEC distributor relocation had problems with timing since it was poorly made. Refer to my thread http://forums.club4ag.com/zerothread?id=99116. In short, it messed up my timing. RHDJapan offered replacement parts for about $150 to update the kit. I have not installed this, but it looks solid. I will be keeping this as a back-up in case there are problems with running the COPs.

Late last year I had problems with throttle response as well as misfiring with the COPs installed. My engine was throwing code for MAP, TPS, as well as ISCV. Went to the local junkyard to get a replacement for the MAP sensor. Apparently the Vacuum line was sealed. Replaced the hose as well. Reset the ECU. Idle was at 2000 but after the ECU learned, it sits at about 1100-1500. Throttle response was restored after driving about 2000 miles in it. Engine also stopped throwing code for TPS and ISCV, so I didn't have to replace those. I still had a problem with misfiring at higher revs from 5000-8000+. Took the plugs out and noticed they were auto-lites and had some build up. Replaced with 98 2JZGTE Denso plugs from Toyota and no more misfiring at high RPM. I do have a problem with oil consumption. I am running 10w40 and about 1500 miles later, it is low. I've read that this particular engine likes to eat oil. I have no oil leaks. Factory manual says 20w50, so I switched to that. Hopefully oil levels stay up there. Other than that, it is a great engine as well as car. Though not as fast, it is a blast to drive. Thanks all and happy holidays!

Just a few clips of startup, revs with open stacks, and 8k climb on freeway. Nothing too big, just using this video for reference. Engine is an AE111 20v Blacktop 4age on an A/T blacktop ECU. Car is an 87 Corolla GT-S Coupe. Nothing major. I felt like recording this on a nice sunday drive. Enjoy. :)

Another update guys. Under the COPs, I had slight misfire around 7000-8000 at WOT. Even when the car was fully warmed up. I switched to colder plugs and no more misfire, even better throttle. Yay, a year after I have been figuring this problem out. Soon after I switched back to the SP-TEC kit since it was rebuilt using better parts, plus I have a new cap and rotor. Throttle response is the same, if not better overall since I first got the car. Installed cusco motormounts so no more engine shake.

Is that DLI off a 4AGZE?

[MistagrimM]

@0S7VN0 It is not. It is a distributor cap/rotor relocator. It just makes it so that you can mount the cap and rotor to the front of the cam gear instead of having to bash the wall in when mounting the engine on an ae86 since there are clearance issues when doing the swap. Sensor is still in the rear of the engine, but capped off.

By the way guys, this video was when I first picked up the car 2 years ago. It had a busted map, slipping clutch, sp-tec timing a little off, no thermostat(just pulled the housing the other day to my surprise, the previous owner did not install a thermostat), cheap autolite plugs that were crusted over, one of the 4 links were bent, welded diff., rear caliper pistons not adjusted correctly, and rear coilovers were put on backwards. All these issues have since been fixed and the car runs strong.

Hi MistagrimM, I'm planning to convert to COP soon. How 'bout throttle response between COP and stock system? Which give more power and throttle response?

[MistagrimM]

@me2kimi honestly I couldn’t tell you exactly if it gives more horse power(which I highly doubt) or has the better throttle response. From experience using both, I could say that both seemed the same to me. If you are doing the COP conversion, really look into your wiring. A lot of problems can occur there. I am switching back to cap/rotor since my kit was fixed. I do run into a few quirks with the COP setup, but it was only meant to be temporary until my sp-tec kit got fixed. good luck!

[me2kimi]

@MistagrimM Thanks for the advice. I'll try it and observe the difference

@kickfreak23 Using BT electronics on a ST engine with either ST or BT harness you will need a MAP sensor and IAT sensor in place of the AFM.

[MistagrimM]

@kickfreak23 Those are just the basics, there are a few other things that you need that I can’t think of off the top. Someone posted a great 20v st/bt > ae86 swap guide just a few weeks ago. Should look into it. My engine, is just bare basics. No heater lines, no a/c, no power steering, no cap and rotor. If you decide to keep those, there may be some fabrication needed. Just a few things to keep in mind. Which is why I’m looking for a stock red/blue top corolla gts just for daily driving. heh.
