6g74 route

[jessecain1]

Hey guys im going the 6g74 route after my car threw time going down I-5.. i've been reading quite a few posts here and on other sites about the swap. The question im getting to is about the ebay listings. They all appear to be the drop in, but im a little sketchy buying from ebay, ive never bought anything for any one of my cars off there and for good cause. Im just looking to get some input from anybody that has bought off there or knows someone that has. Im i just being pernoid or???

They all come from chop shops so drop in really isnt what it seems, if you notice hoses and wires are literally cut in half and left attached to save time.
As far as quality, from what I've heard they are hit and miss. Its up to you if you want to take that chance. Id try searching local listings, junk yards, or forum classifieds first.

Again im not saying people dont have success buying ebay motors, but I would probably pass unless I knew I was going to rebuild it anyway.

Also, the mitsubishi japanese debonair engine and/or one that 100% came out of a 3000gt is the only one that drops in without modification.

That's the selling point, if it's not from either one of these, do not bother.

well from what i understand the way you tell if it is a jdm all the accesories will be on the same side as are cars, and it appears all the ebay ones are correct. So when they claim to be under 40,xxx miles how do you tell. sorry if im sounding really newbish, im just trying to get a better understanding before i dump $1500 or so dollars on a motor.

like this onehttp://cgi.ebay.com/ebaymotors/JDM-Mitsubishi-6G74-3000GT-3-5L-DOHC-Montero-Stealth-72-_W0QQcmdZViewItemQQhashZitem19c0900c1dQQitemZ11060 4848157QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccesso ries

i also noticed they where all listed as montero's, but have heard that they may actually be out of pajero's/ diamente's

My friend purchased one of those 3.5 engines, and for the month or two that it ran it was a hell of a lot of fun. But then it spun a bearing. He always says if he ever does another one of those engines, he will first rebuild it before putting it in. The 3.5 that swaps into our cars is out of a Debonair. They come from cars that were made in the 90's. More than likely the engine has sat for a long while, and when they sit without being turned over, and take a trip across an ocean of salt water, I can't imagine they fare well. Source the parts you need for the rebuild, and buy one. Thats what I would do. Then you know you got a good engine as long as your skills as an engine builder are good.

Yep, I was lucky with mine. Sat on a tyre for over 3 years. I've now done about 8000k's on it and it's been sweet as. Seen 7000RPM many many times!
They have a whole whack of torque in these!

Wow, where to start. First of all, this page by John Monnin (Wrenchmonkey) goes through the entire process in detail:

http://www.wrenchmonkey.com/Webpages/6G74swap.html

Go here first, read and profit. This is not a direct swap by any means, but it really isn't all that complicated provided you got all the accessories off your 3.5L engine and kept the stuff off your 3.0L as well. There will be some amount of swapping, grinding and cutting to make it all work.

Xwire did this conversion in my 98SL in 2006, and the car still runs as strong as ever. If you take your time, source the correct parts, and don't get crazy, you should have a very strong car, especially if you're only staying NA.

If you're going turbo, it's a different story entirely, and will require another sizeable investment in internal parts, turbos, fuel and engine management/tuning.

I posted a thread about all this a while back...

I got a 6g74 block for $200 USD...I'm doing a full rebuild/bore anyway so it's overall condition isn't a huge problem

If you use a Debonair 3.5L in a FWD 3000GT N/A, then yes, its a 100% direct swap. Old engine out, new engine bolts in (provided like you said you have everything to it!) and from there it should even run no worries on the 3L ECU.
