mitsuorder's 4g69 experiment
Let me start this off with the fact that this is an experiment. I began with wanting to push the Evolution IX Mivec head/4g69 block combo to the limits so as to provide information on a potential option to the community. Huge advocate of sharing information, the good, the bad, the ugly. Hiding it does nothing for any of us.
With that said here is my 6466 4g69 build. Heading out of the country in October for a while so wrapping it all up this month. It is not running yet but everything is here. Been a lot of planning, looking at what was available, and simply wanting to do things right. Least competitive person you'll ever meet so check the machismo neanderthal stuff at the door please {thumbup} I will be updating this and answering any question to be had. Have held off on putting it all up as I didn't want to lead anyone in the wrong direction since nothing has fired, run, or blown up as of yet haha. But seriously though guys, this is an experiment. I did it because I wanted to see what would happen with this iron block if you pushed it with a build that has had no real limit, within reason, or deadline. So here are the pics. 4g69 out of an '05 Ralliart which had hydrolocked from a cai. http://img703.imageshack.us/img703/2066/44580817.jpg http://img209.imageshack.us/img209/4568/94706528.jpg Supposedly the lightest 100mm crank Mitsu had made up to that point in time. Let's see when she lets go. http://img822.imageshack.us/img822/3676/18242664.jpg I wanted to test fit the old ix block's water pump before ordering anything for sure. Evolution VIII and IX water pumps fit this block like a glove. No spacer or modification needed. http://img819.imageshack.us/img819/1765/57750458.jpg Cosworth h11 tapered tip head studs http://img685.imageshack.us/img685/5733/58430731.jpg As per their instructions a torque angle gauge was required for sequencing. For anyone who has used these or is considering so that is a LOT of torque. http://img401.imageshack.us/img401/1954/24362533.jpg Prob the same h11 tapered that everyone else sells but with some laser etching. Got a deal on them and felt like being a brand whore one night. http://img801.imageshack.us/img801/9545/48306415.jpg Figured why risk reusing lifters that have debris in them and why not finally upgrade to see if lifter tick could be alleviated a bit. Snagged some ITM big bores. http://img687.imageshack.us/img687/3810/32543062.jpg Since I was deleting the balance shafts I saw no reason to keep the associated gear. Replaced it with what I believe is the crankshaft sprocket/spacer from a 1.8. Mitsubishi part# MD128107 from the great guys over at www.Mitsubishiparts.net http://img339.imageshack.us/img339/9884/87944316.jpg The original piece. http://img19.imageshack.us/img19/7538/73749879.jpg Went with the Tomei oil scraper for the crank. Verified fitment with a 100mm crank. At least the oem 4g69 piece. Thank you Touge Factory. http://img594.imageshack.us/img594/9189/91075054.jpg This was one of those parts that I was definitely not expecting to be so impressed with. Very well made, heavy duty piece. http://img40.imageshack.us/img40/9207/72863031.jpg http://img696.imageshack.us/img696/5636/24708468.jpg Gaskets and all oem assembly items provided by www.Mitsubishiparts.net http://img339.imageshack.us/img339/5521/97320304.jpg Had some 87.5mm Platinum Series 9.5:1 pistons made by Manley when I ordered the 150mm I beams. Yes, I went .20 over an 87mm bore to clean things up. The world is going to implode while the baby Jesus cries at me. Again, let's see what this block can take. http://img16.imageshack.us/img16/866...0912201753.jpg Went with Power Enterprises for the head gasket. http://img818.imageshack.us/img818/7918/82986839.jpg This is an excellent choice for this head/block combo as it fits them very well along with taking full advantage of the IX head and 4g69's large coolant passages. http://img96.imageshack.us/img96/3254/81032522.jpg The extent of my photographic skill. http://img41.imageshack.us/img41/8504/94890271.jpg Head consisting of Ferrea 6000 series factory sized valves, Ferrea manganese copper intake and copper alloy exhaust valve guides, Viton seals, Kiggly steel base washers, springs/titanium retainers, hla, and factory locks/keepers. Cams are Kelford 9-TX280, 280 intake/276 exhaust. http://img838.imageshack.us/img838/7167/22056331.jpg Massaged the combustion chambers a bit for the 87.mm bore. http://img208.imageshack.us/img208/7825/75614936.jpg Tapped and plugged the egr port on the head for good measure. http://img152.imageshack.us/img152/8889/51761506.jpg Pretty Kiggly hydraulic lash adjuster. http://img690.imageshack.us/img690/7339/45205284.jpg Magnus v.5 cast intake manifold. http://img507.imageshack.us/img507/1429/40824328.jpg Cleaned up some of the casting marks on the inside. http://img407.imageshack.us/img407/1974/68173766.jpg http://img69.imageshack.us/img69/4897/40787303.jpg This is the necessary modification needed if wanting to run a Full Blown 70mm throttle body with the Magnus v.5 along with opening the adapter plate up to match the throttle body's inner diameter. http://img577.imageshack.us/img577/6825/15984181.jpg Magnus fuel rail http://img713.imageshack.us/img713/2979/56606115.jpg That should do... http://img16.imageshack.us/img16/6852/57830244.jpg Full Blown 70mm cast throttle body. Thanks to the guys at MaPerformance In particular I like the factory like placement of the iac valve on this t/b. http://img840.imageshack.us/img840/7205/45767770.jpg ID 2000's from Mr. Palo himself. Repinned the clips instead of using patches to avoid any vibration related incidents... http://img805.imageshack.us/img805/9434/51524572.jpg A whole mess of Full Blown fittings for the fuel system. http://img593.imageshack.us/img593/8401/66294821.jpg All flow formed on the inside. http://img818.imageshack.us/img818/7644/17562420.jpg Utilizing factory feed line as my return line.

I like this stuff because it's nylon braided on the outside so as not to chew through everything with a substructure of braided stainless on the inside to give it great strength in tight radius bends. http://img835.imageshack.us/img835/9463/73277795.jpg Gutted factory pump hanger. -10 pickup. http://img201.imageshack.us/img201/972/37349328.jpg Was worried about overflow issues from the small id of the pick up fitting. http://img9.imageshack.us/img9/8799/54956210.jpg So will test this modified one out. Either way I'm running an Aeromotive 16306 fuel pump speed controller so problem easily solved. (Factory siphon fitting absolutely would not work with the amount this pump flows anyway. Ditched it in favor of a Magnafuel Y and a -10 pickup in the passenger side of the fuel tank.) http://img834.imageshack.us/img834/6366/18910368.jpg http://img716.imageshack.us/img716/3752/89821785.jpg Fuel system class pic! http://img560.imageshack.us/img560/9551/51037643.jpg All assembled at 75 *F http://img542.imageshack.us/img542/5372/53694208.jpg http://img833.imageshack.us/img833/7891/30858415.jpg No more balance shafts so thought I'd utilize the front crank case hole for drainback of the catch can system. -6 fitting.

These are just parts gathered over the past two years to give you an idea of what is going on in my head. Ask away, try to stay cool/respectful to one another/maybe even me :) and let's see if this thing doesn't just do something neat {thumbup} e85 at 39 psi and dyno vid: mitsuorder |
holy crap this is epic good job so far
|
Hey I really appreciate it man :)
|
nice to see it all laid out like this. anxious.
|
This is a crazy build excited to see how this turns out.
|
quite awesome, can't wait to see the results..
|
Sweet build you have going so far. I can't wait to see what it'll do.
|
Definitely looks like some time was spent doing your home work. Looks like everything will look great in the end and I'm sure you'll get some good results as well.
Good luck with everything |
Wow your build is awesome! I really enjoyed going through that first post!!
|
Looks great. Really like seeing what you are doing with the 4g69. So what rod size are you running? Also did I read that this is a 100mm crank in stock form? Did you happen to weigh it? What are your RPM goals?
|
Interested in the results of the 4G69, great job thus far!
|
very nice...you did not mention it, but did you opt to have oil squirters installed in the block? the passage is there, you just need to tap into it...what's the PTW with those pistons? and 9.5 is stock compression, i can't wait to see what this thing can do...
I rev mine to 7200. |
Thank you again to everyone for your support and kind words. Fighting a fever right now so let me try and address everything asked.
I'm running a 150mm Manley I beam. The crank is the oem 4g69 100mm crank from Mitsubishi. I did not weigh it unfortunately but am sure with the relative ease of availability of these blocks finding one to compare to that out of a 4g64 would not be difficult. With the rod/stroke ratio of 1.5:1 I'll prob only be taking the engine up to 8000 rpm. Didn't tap the block for oil squirters. Just a personal choice in regards to keeping things simple. I'd be lying if I told you I knew the ptw clearance of the pistons. Could ask my machine shop if they still have the info. Stock compression is 8.8:1 I believe so 9.5:1 seemed to be a nice in between. All that I lack to assemble the car is the exhaust manifold and it's being finished up as I type. Will be a weekend assembly/exhaust/charge pipes/tune event at my friends fabrication/tuning facility. Hoping to have it all wrapped up this month before I take off. Keep 'em coming, mitsuorder |
Sorry, I was thinking 4g63 cr.
|
Great write up and build. Thank you for the information on where to get some parts.
