DarkMitsu's 4g64 Swap Page
Thanks for the info! Wouldn't it be easier to just convert to manual while I'm swapping the engine out since the car is going to be torn apart anyways?
Work has left me with little time to research this, unfortunately. When my 3 week break from college comes around in a few weeks I plan to hunt down and buy everything needed for the swap. RRE (www.roadraceengineering.com) has a nice list of SoCal importers which is a great place to start looking for an engine.

ok guys I dynoed it today...
peak torque 130 @ 3800 rpm peak horsepower 107 @ 5000 rpm this is to the wheels
This is with a completely stock 2.4 , using stock lancer airbox and stock lancer exhaust...
looking at the dyno print off my car will drive best / be fastest if kept between 3800-5000 not much of a reason to rev any higher than that because all the numbers fall off up top...

yes I agree it did seem low but I was told this dyno reads to the wheels , not to the crank , the number's you get from factory specs are usually to the crank... But in any case we can all go stand in the N/A corner and cry about it... I cant imagine what HP/TRQ numbers my other motor put out because this one pulls way harder than the 4g94.

the factory specs on the 4g64 are 140ish. i know on the eclipse spyder it was 141. there is usually a 10-20% drivetrain loss, although every car is different. so i would say you are still on the low side, even if you took the 20% = 28hp would put you about 112hp. as a GENERAL rule though the 20% drivetrain loss is for AWD setup and FWDs are closer to 10% than 20%. my prelude had an 11% loss. so if it was me i would say 15% and that would be 21hp loss and would leave you with 120hp approx. so the 107 does sound a little low. congrats on getting a good baseline to move forward with.

its not tuned at all , I havent got a wideband to mess with it , and the stock intake pipe is quite restrictive , and stock lancer exhaust is smaller piping size than the eclipse exhaust pipe , and this motor is by no means a low mileage motor it has at least 120k miles on it if not more... But this also proves rpm_ruffryders cam/exhaust/intake upgrade are a must contact him about the special cut cam he had made, and this motor pulls way harder than the stock 4g94 did so I cant imagine the low numbers one of those would put out I may have to upgrade the intake/exhaust/cam and put it back on the dyno, this will be after I finish with my 2jzgte mk3 swap taking up my garage space.

1/4 mile times will come , as soon as my buddies eclipse build is complete , we will be going to the track and will be running the lancer as well in the form it is now... Jeez to many projects at the same time... that 95 eclipse gsx is gonna be sick 2.4 4g64 sbr stage 1 or stage 2 bottom end (dont remember which one he order) , dohc head , t3 30r 4 inch anti-surge housing , dnp t3 manifold , maf-t pro , 650cc injectors , 44mm tial wastegate , hks ssq bov , front mount i/c , custom hard i/c piping , act flywheel , act clutch , walbro 255lph intank fuel pump , aem wideband , autometer oil pressure , autometer boost gauge , apexi turbo timer, k&n 4 inch filter ...
very nice build. I like what has been done but i do have one question. You made 130 torque and 107 hp. That's a 9 lb of torque gain from my 4g94. How many miles were on your old setup? And what is your next step in this setup?

My car is an 02 lancer es sitting at 141k and climbs about 1k miles a week , it is a daily driver and I drive all day long in it . My original engine had the timing belt strip all the teeth at the crank gear @ 110k miles or so . I called around and did my research apparently the 4g94 is an interfearence engine , but I took it appart after the fact and the internals were fine no bent valves , couldve just put a timing belt on it but I ended up swapping it with a 4g94 engine from a 06 with less than 10k miles on it (ran the vin# from the car it was basically wrecked off the lot) I drove on that engine for 4-5 months and came across an eclipse that had been totaled that car had 100k miles or better on it but it was the right price so I got that for my engine swap that I had been wanting to do since I got the car, I havent really decided I've been doing some reading and I might be doing a 4g63 swap those engine will bolt to the eclipse tranny. I really want to do rwd conversion , I found a guy who makes bellhousings for the r154 tranny to the 4g63/64 block (from the starion/conquest boards), but I gotta keep it simple it is a daily driver and needs a/c power steering ect. havent really decided which route yet , maybe turbo , maybe a camshaft , port/polish head , outlander intake manifold (I'm lucky I havent cracked the welds on my intake manifold < I'm serious about that all jokes aside), headers but still gonna keep a quiet muffler on there , definately needs a bigger radiator and a SRI , could also use some polyeuruthane bushings as well only time will tell...
