  1. 4G Eclipse GS/SE Specific
    Has anyone swapped for another model of 4g6 engine? How hard is it to swap for a 4g61 or 4g63? Do the sensors plug in to the old ecu or how would you control it? I’m well aware ours can make good power I just want to see what people have to say about this.
  2. 2006-2012 Eclipse (General 4G)
    So i've been in the middle of a rebuild due to a timing belt which lost all of its teeth. To save myself a little work, I picked up a used 4g69 head with 1/3 of the miles mine had. I lapped the valves, got everything together with assembly lube, it's the new head, my original camshaft (more...

    So last week I picked up a ripp supercharger for my 07 eclipse gs 5 speed m/t however I put myself in a bind since I’m heading to Harley tech school in august. So I’m wondering how much I could sell the kit for, comes with 565cc injectors, greddy type s bov, water tank, triple gauge pillar, oil...

    Part 1: I’ve been doing research through the forum and haven’t found a specific answer, will a 3g 5spd tranny fit in the 4g69?? I haven’t seen anything about it being done only thing I’ve seen is the rumor that it works but just need to fabricate a new linkage for the shifter. Is this all bs...
  5. 4G Eclipse GS/SE Specific
    So my 2012 gs eclipse threw a bearing that is my current assumption. Do not yet know what I’m gonna be dealing with when the engine is pulled but lots of metal in my oil. As long as the block is not messed up I plan on boring it out and getting a rebuild kit as well as possibly some performance...

    Does anyone know if rre still has those turbo kits or if anyone knows who sells a turbo kit for the 4g69
  8. Problem Reports
    currently have a 4G69 in a 12’ galant. Used a 4-4-4 header but can’t remember the exact parts dealer but it was a really good rated one interchangeable to all 4G69 engines. Cat back straight pipe and weapon r sr intake. I installed new o2 sensors that fit nicely into the headers but these are...

    Just curious if anyone's attempted to bolt a 4G69 up to a GSX trans? Curious as to what kind of work would likely be needed. I've got an AWD Talon TSI with no motor in thinking about swapping a Turbo 4G69 into. Any insight would be great, would be my first swap.
  10. 4G Eclipse GS/SE Specific
    Hi, I'm New to the 4G69 and I read somewhere on here about an updated timing belt tensioner that helps prevent premature failures but couldn't find any info on the differences or a part number and I just bought an "07" Eclipse GS that had the belt failure and will be ordering parts soon. Any...

    I have quite a few things I've been upgrading on my car and I'm starting to just have a shelf in my garage of car parts, so I'm looking to get rid of some of them. The parts are as follows and will be adding images with proof of me as soon as I take them and inventory them in this post. Any...
  12. 4G Eclipse GS/SE Specific
    Came across this intake manifold from the G4JS: same bolt pattern as the EVO, meant for a 2.4L, runners longer than the EVO but short that the 4G69. Sits a bit taller due to the runner shape(L vs U). I bolt it up to the 4g64 just for reference(nevermind the distributor, it was making it possible...
  13. Forced Induction & Nitrous
    I have been looking around and it seems that RRM makes turbo kits for the 2000s lancer ralliart that shares the same engine, 4g69, with us. They also make performance parts for the 4g69, like port and polished intake manifold, and turbo exhaust manifolds, that in the site, they say it fits the...
  14. 2006-2012 Eclipse (General 4G)
    I know there has been many threads about engine builds and interchangeable parts for the 4G69 but I want this thread to strictly focus on the history of the max power (horsepower/torque) that has been achieved with the 4G69 engine before boost. I’m wondering what is the statistical limit of...
  15. Automotive For Sale/Wanted
    Perfect for a turbo build, the kits are available once again. This new kit is very similar to my old kit, however it reflects the price changes in the last 4 months, and now includes ARP head and main studs. These are all parts I have personally tested and abused. I have my motor happily revving...
  16. 4G Eclipse GS/SE Specific
    I ordered some titanium spring retainers that are meant for a 2jz beehive style spring that happened to measure EXACT to the 4g69 spring. I will post pictures as soon as I get them in!

    everything lines up for top dead center except the oil pump. is it possible it jumped a tooth on the oilpump? WIll that harm my engine? I will of course put the oil pump back in time when i replace the belt, just waiting on parts. Im just wondering if there is anything special i should know...

Got the car for $600 and drove a little. the car was in time when I purchased it and before I began to work on it. I have so far taken off the...

    I have a set of 87mm 4G69 pistons, never been used. They're ~U$650 retail, I'll sell them U$575 shipped in continental states or Canada provinces. These are the extreme duty ones, not the standard forged pistons I didn't use them because I wanted to get perfect piston to wall clearance for my...
