  1. Just to add my research to this thread for 4efe. Have not measured on an actual vehicle yet. The 4efe (gen 2) Starlet 96-99, 4efe (gen 1) corolla 92-97 and 4efe (gen 3) corolla 97-99 and 5efe Paseo 95-99, all list the same fpr part number (23280-11070). There is no Starlet Haynes manual but there are for the 'rolla's. (92-97 rolla shown below) They both show a base fuel pressure of about 2.8bar and manifold referenced fuel pressure at idle of about 2.4 bar. That is what the Haynes manual states is correct. Can't say for the 4efte as it uses a different reg (23280-1104
  2. From the online parts catalogue I use: Doesn't say deg c in the description but neither did the ep91 listing and the Starlet thermo is marked 82 deg C so it's a safe bet.
  3. From memory to access the turbo to manifold nuts I needed to use offset spanners: Most people remove the manifold with the turbo still attached to it because the bolts are hard to access. In my experience the Toyota EP91 4efe/4efte thermostat (90916-03046) is stamped as 82 deg C which is what I removed from my engine. The Toyota epc states 82-95 (I assume this is starts to open at 82, fully open at 95). Found the euro Paseo 5efe 95-97 thermostat (90916-03082) rated at 76.5-90 deg C
  4. If you scroll up to the top of this page I already did. 😉 Click on the link and it will take you straight to that page of my build thread. The lumps in #2 and #3 runner are the worst. There is a small amount to remove from #1 and #4 but they aren't that bad. Happy grinding!
  5. First I would check that the manifold is actually cracked. Sometimes a damaged / leaking gasket can cause the same noise. You need to inspect the manifold for cracks. Look for black soot marks on the manifold and head. You can also hold a piece of tissue next to the manifold / gaskets and watch to see it blow as you move it around different places. As far as manifolds go I would avoid all the cheap stuff on eBay as it usually doesn't fit the engine very well and cracks very quickly. The CT9 Tubular manifold Tuning Developments sells seems ok as the first upgrade, hopefully someone us
  6. When I removed the sump on mine I noticed that the corner of the top lip was bent from tapping in a screw driver to brake the seal. Managed to hammer it back flat again. They do sell repro EP91 style pans on eBay for about £50, not sure on the quality or fitment though. Might help if a Glanza one is unobtanium.
  7. No worries, didn't think that for a moment .
  8. Didn't know that there were different versions. Thanks.
  9. Unfortunately I don't think 210cc will be big enough for turbo applications unless you're running low power. There are many online fuel injector size calculators that will help choose the correct flow rate and also calculate the increase / decrease vs the fuel pressure also. Not sure if you're talking about direct injection when it comes to spraying on cylinders. I was referring to port / manifold injectors and their nozzles. The changes in design over the years from single spray to Bosch disc type with 4 small ports (mx5 etc) https://www.witchhunter.com/spraypattern1.ph
  10. No worries, just trying to help. I love your enthusiasm and your willingness to help the Starlet community. There's plenty of topics relating to n/a tuning on this forum. Might be worth a read mate. Sorry for the tangent.
  11. If we're talking stock engine / with corolla manifold I wouldn't bother increasing injector size (the 195cc are plenty big enough), if you're talking about adding the same size injector with the same resistance but a better pintle design / spray pattern than denso I could see that working. The problem with just "dropping in" injectors is that the ECU doesn't know the size difference. When running in closed loop the narrow band O2 sensor will adjust the fuel that is delivered with short term and long term trims (assuming it has the the range to do so) but in open loop (full throttle e
  12. Not sure the oil grade helped, according to the 4efe owners manual the recommended oils are shown below: Most people seem to run 10w 40. The tolerances for the engine will be designed to use a range of oil grades but straying from this can lead to problems. When increasing grade the oil pressure should increase also but flow must surely decrease. The bypass valve may be able to even the pressure out though. I would say from comparing them to some online charts that it looks like fatigue failure and / or lack of oil / too tight oil bearing clearance. Detonation is a real possib
  13. Cusco brace looks great Callum. Can I ask what the yellow injectors do for an n/a? What size are they?
  14. Check the idle control valve as the topic you quoted says. Unplugging it will help isolate if it's the cause. If it's not that, it could be the valve clearances or injectors tick as well. But neither of these usually get that loud. If you do have low oil pressure at start up that needs to be fixed. Some use a mechanics stethoscope to listen to different parts of the engine but I've always used the "long screwdriver to the ear" method. It helps identify the source of sounds very well. Be careful not to hurt your ears / hearing though!
