    Hello, I am having some trouble getting the exhaust manifold off in my 1991 na mr2 I am trying to replace the gasket. I got all the studs off I believe and can move the manifold but I am running into a hanger that connects to the cat at the bottom. I removed the nut on the stud that connects...

    hello, this might seem like a stupid question but my 92 mr2 (5sfe) rubber pcv valve grommet finally was just to brittle so when i went to go replace it with the new one it broke so i went and bought another one and it broke so after trying a third time i realized it just doesn’t fit right but...

    Hello, My 92 mr2 (N/A 5SFE) has this issue where if I don’t drive it for more then a day when I do go to drive it, it will stall/die out after returning to idle if the rpm’s go over about 2k. After it does that about once or twice it drives perfectly fine but the idle will sometimes come really...

    Hi guys, I recently bought a non-running example and the owner’s SIL said it needed a fuel pump. It cranks but won’t start. I checked under the car and it was covered in oil from the bottom of the intake manifold to the oil pan and transaxle. I haven’t gotten a good battery in it...

    Curious what my best options are as far as NA exhaust systems go? Got quoted close to $1k at a local muffler shop and the only reputable bolt-ons I can find are around that same price range. I'm not necessarily opposed to spending that much but wondering if I need to. Would appreciate any...
  6. MKII, 90-99 NA & Turbo
    So my na cali 91’ mr2 has aftermarket exhaust system including headers which means no cat and weird o2 sensor problems. PO added a heated o2 sensor for the upstream and a normal for the downstream but recently i popped a code 26 which i had to replace both of the sensors along with a heated...

    Ok so I have a 91 mr2 na and I just finished putting in a rebuilt motor and everything is hooked up correctly as far as I know but when I go to start it sometimes it'll crank with no start and whit smoke comes out the intake and sometimes it'll start right up but then it just revs up and dies...
  8. 3SGTE Turbo
    Okay, hear me out or tell me I’m nuts. I’m sure by now it’s common knowledge that distributors for the Gen2 3SGTE are less common than we’d all like (especially considering the price used ones go for). But for those of use with standalone ECUs, would it be possible to use the 5SFE distributor on...

    I want to eventually upgrade or swap my 5SFE and was reading the commonly asked forums. I want to ask if it is worth upgrading my 5SFE to a race build or just swapping to something like a 3SGE/3SGTE or a 2GR considering the time and money. It will be a weekend performance driver and I will be...

    I need some help figuring out what to do with my car. I want to swap it over the winter and have it ready by next summer (not sure how realistic that is) but I honestly don't know where to start. Originally, I thought gen4/5 was the way to go until i started looking for wiring diagrams and...
  11. 1990-1999 MR2 N/A Cars For Sale
    Purchased earlier this year, I thought it'd be a decent project car. I didn't know anything about MR2s and ended up getting jipped. It runs but apparently the head gasket needs to be replaced because it started smoking like crazy so I took it to my mechanic. He said its probably the head gasket...

    Hey Everyone! I hope this is alright. I recently posted this on a older thread from 08. Curious if you guys have found out how to make the most of your 5sfe's. Hope I'm aloud to post, my wife has had a Gen 5 Celica gt for the last six years and we love it. Want to turn it into a reliable daily...

    I need a new fuel pump for my 1993 mr2 with the 5sfe in it what should I get?
  14. Normally Aspirated
    Hi everyone, first-time poster here! Need some opinions. TLDR: Crank, no start. No power to fuel pump. Sometimes no spark either. New Circuit Opening Relay (cor) didn't fix it. Mechanic's technician put in a new COR and said it was fixed and that the one I got new from the dealership was bad...
  15. MKII, 90-99 NA & Turbo
    So little back story, got this car a couple of months ago, has a rebuilt engine with paperwork, and I've been fixing everything else back to operating standards. Went to change the oil, I referenced the owner's manual that thankfully came with the car. It says 4.2 quarts with filter. Now here's...

    Hello, Been having issues with my mr2 making a fast ticking noise (like a fast clicking ballpoint pen) from the engine. Seems to be most audible around 2-3k rpm and accelerating in 2nd gear. No sound when clutch is depressed I believe. At first I thought it was the exhaust manifold+gasket so I...

    Hi, new here. Tried to find the answer but most posts are old and pics end up with a 404 not found error. I recently picked up a clean MR2 nonturbo 5sfe with a rebuilt engine. Apparently, the mechanic that put it in did not want to do it (I assume this is because it was intimidating) therefore...

    Friends! I replaced my battery last October and as soon as I brought her out of storage in March she was completely dead. I threw my jump box on the battery and within 1 minute she turns over. However, if i keep the jump box on the battery for a few minutes while running, the idle starts going...

    The clutch on my '95 N/A slips so I've been looking for a replacement, and with it, a lightweight flywheel, as of now I'm thinking of the exedy OE replacement clutch kit and Fidanza lightweight flywheel. I wouldn't be pushing more than 150 hp through this clutch as I'd be getting a new one with...

    Hello all, in the process of swapping a new tranny in my sw21 (5sfe mr2) and am curious why I've been finding that this swap won't work. The bellhousing of a c64 looks to be very close in bolt positioning to the s54. Does anybody know specifically what makes this swap impossible? I've looked and...
