  1. MKI, 84-89 NA & SC
    Ok so just did a compression test on my 86 mr2 and all 4 cylinders are low on compression, while 3 of the cylinders are above the minimum 128psi one cylinder is below and they aren't with 14psi of eachother as the Haynes manual recommends. Adding oil while doing the compression test adds some...

    Got a second hand Gen3 head with injectors, rail etc. Is it a straight swap i know the timming set up is different as i have a spring type tensioner and the newer head is hydraulic type but other than this would it be a straight swap?
  3. 3SGTE Turbo
    Hi fellow owners I'm in a little bind and need your assistance. Long story short I haven't driven my mr2 turbo rev 3 in a while and the battery cut out as I tried to start her up. Jumped the car and all electrics work apart from the imboliser red light. Car central locking still works etc...
  4. General MK1 - FAQ
    Hey guys, so I own an 86 AW11 A NA and I wanted to swap the engine for a more powerful 2L turbo. I thought about 3SGTE swapping it like a lot of people do but I'm having trouble finding any and even less with a manual transmission. Budget is tight so for me it was a pretty good option but it's...
  5. General MK1 - FAQ
    My engine is loping significantly at idle. I really cant describe what's going on well in writing, but I'll attach a video (link below) so that you can see (mainly hear) what I'm talking about. Any help in diagnosing issue is welcome. Note: I'm aware of the vacuum line being disconnected from...

  7. New Member Introductions
    Hi everyone, this is my first post here. I've picked up a 1992 Rev2 with a 3sge and I was doing a bit of investigation and it doesn't seem to have an o2 sensor anywhere. The downpipe needs replacing and I can't find one without an o2 port (like the one that is currently on the car). There are...
  8. MKI, 84-89 NA & SC
    I let my brother test drive it one time and he blew out third gear. So I did the right thing, and pulled the entire engine and replaced the transmission with a C52. Upon reassembly, I cannot get the car to start. Initially the grounding was bad due to a cut ground wire. Checked spark, timing...
  9. Common Engine Swaps and Related Discussions
    Hi, I have a 1991 MR2 that was originally NA but was engine swapped by the previous owner. I bought it when I didn't know what I should have been asking about so I have no idea if the clutch or transmission was changed with the engine, and sadly no longer have the seller's contact information...
  10. MKI, 84-89 NA & SC
    Hi guys, I'm considering doing a MK1.5 build, and wondering what I might be able to get if I sell my current engine, which is a 20V blacktop, that I had rebuilt by a shop. It only has 40,000kms on it since the rebuild, summer driven only, stored in heated garage in the winters. Can anyone guess...
  11. Tri-State MOC
    I am reaching out to the Tri-State local MR2 crowd to see if anyone is interested in a completely disassembled 5sfe? It was the original engine to my 91 that had a bad bearing. I pulled the engine and swapped in a lower mileage 5sfe and have been driving it ever since. It had roughly 105k...
  12. 3SGTE Turbo
    Hello Mr2oc, Just a little background about me. I recently purchased a 91 mr2 turbo with 123k miles several months ago and its been a fun car to drive on the weekends (Daily a 08 SI). I've been using this site as a reference in order to familiarize my self with the Mr2 and it's community...
  13. MKII, 90-99 NA & Turbo
    I know there are threads on here about this topic, but the symptoms people are having dont all add up to what my car is doing, so i thought id post. This is a 3rd gen that has been swapped in a few weeks ago. So the problem is that during idle and acceleration to about 2500 rpm, my engine...
  14. MKI, 84-89 NA & SC
    Hey guys. I have an 87' MR2 with a 4agze swap and i'm having some issues with the amount of smoke it puts out. It starts fine, but if you let the engine idle for awhile or give it throttle the engine starts to pour out a lot of smoke both from the exhaust, and from where the exhaust manifold...
  15. MKII MR2 Parts Wanted To Buy Or Trade

  16. Normally Aspirated
    Greetings, everyone! Yesterday i was driving down the highway at about 80 MPH and suddenly i noticed that when i pressed down the gas pedal, the vehicle wouldn't respond and go faster. I immediately took the next exit and popped up the engine bay lid to see what was going on. My first thought...

    Ok here is the start of my thread to solve every issue I have with the 5sfe. I'm a new owner to toyota mr2 I've been a Honda guy for the longest and I've been looking to switch over since all of my family member are toyota lovers. N/A 5spd 72k miles. 1. To start off having hard time starting...
  18. General MR2 Discussion
    Novice question, but the mr2 is my first car and I'm looking to change the oil on it soon. I was wondering what is the best oil to use? NA 5sfe Thanks in advance.
  19. MKI Cooling & Charging
    I just went to check an MR2 for sale and the only catch is there is a coolant leak. Its not terribly bad but I haven't found to much on what it might be on here or other forums. My best guess its coming from around the A/C compressor somewhere. Looking down in the engine compartment I couldn't...
  20. MKII, 90-99 NA & Turbo
    Hey Guys I know very little about cars and have just had an issue, my car (1990 MR2 manual non turbo) is not accelerating at its usual rate at all. It started just yesterday, and under 60kms/h even if i put my foot down to the floor it just accelerates fairly slowly - nothing compared to what...
