yello620 Posted October 16, 2009 Report Share Posted October 16, 2009 (edited) Here is the beginning of an attempt at installing a VG30/Automatic into a 620 pickup. So far there has been no cutting of the tunnel, but it is going to happen. clearances just are not there yet. Right now it is tight to the tunnel, would need a ball peen hammer clearance job on final install. But not quite enough room for the oil pan pickup tube where it sits, but it could be done. And the biggest problem so far is the starter wants to go right through the torsion bar. Next step will be cutting the tunnel a little. This should get the crankshaft a little higher in the frame and make the oil pan fabrication a little easier, and make the starter clear the torsion bar. Might only need to move up about 3/8". Teaser pictures. Edited October 17, 2009 by yello620 1 Quote Link to comment

bonvo Posted October 16, 2009 Report Share Posted October 16, 2009 why not go front coil overs and eliminate the torsion bars all together 1 Quote Link to comment
fisch Posted October 16, 2009 Report Share Posted October 16, 2009 I'm super excited about this Yello! 1 Quote Link to comment
yello620 Posted October 16, 2009 Author Report Share Posted October 16, 2009 why not go front coil overs and eliminate the torsion bars all together This is a very good option. I have two things that keep me from it at this time. First is that i am hoping for this to be a repeatable conversion for other people that might want to do something other than the KA.:D Second revolves around the first. I wanted this to fit into a mostly stock chassis. I do plan to airbag my truck someday, but that is a conversion in itself. Didnt want this to be a two part conversion just to get the VG. It is not mounted yet, so i may decide that it wont work to my satisfaction. If that happens, then i will probably go the default KA route. 1 Quote Link to comment
slam_dat_sun Posted October 16, 2009 Report Share Posted October 16, 2009 SWEET keep up the good work , I love the teaser pic but I hate it at the same time :lol: . It is nice to see it but at the same time it makes you want to see more haha 1 Quote Link to comment
yello620 Posted October 16, 2009 Author Report Share Posted October 16, 2009 But also notice in that picture that there is a A/C compressor already mounted.:D The alternator is also mounted. Both using factory brackets so far, but the alternator will require a custom upper bracket for adjustment or a tensioner pulley. 1 Quote Link to comment
fastdadd Posted October 16, 2009 Report Share Posted October 16, 2009 what if you found a smaller high tourqe starter to fit in there 1 Quote Link to comment
yello620 Posted October 16, 2009 Author Report Share Posted October 16, 2009 I havent found that yet, but i gat a lead that i am going to follow up on.:D I have discovered that nissan used two different starter mounting styles. One style has lots of options, the other style has only a few. Guess which style i got.:mad: And there doesnt seem to be any aftermarket gear reduction stuff available, most likely because they are a gear reduction starter from the nissan. 1 Quote Link to comment
Pacific coast Datsun Posted October 16, 2009 Report Share Posted October 16, 2009 Is this going into your truck? I applaud your efforts / never seen it done on a 620. 1 Quote Link to comment

yello620 Posted October 16, 2009 Author Report Share Posted October 16, 2009 Is this going into your truck? I applaud your efforts / never seen it done on a 620. The plan right now is to put it in my truck, but since this hasnt really been done or proven to work, i picked up a donor truck to mock it all up in. Basically i have a 75 620 that is not much more than a shell. I cut the core support to make the test fitting easier, but that wont happen to my truck. Things look good right now, but i i decide that it won't/can't work, then i havent taken my running truck apart.:D Right now the biggest problem is the starter.:mad: 1 Quote Link to comment
Farmer Posted October 16, 2009 Report Share Posted October 16, 2009 IVe been wanting to put one of those in a 620 since the early 90's. Hope it works out for you. Larry 1 Quote Link to comment
fastdadd Posted October 16, 2009 Report Share Posted October 16, 2009 there are a lot of people that have been wanting to do this you make it work and you will become a god among men....:lol: and if i didnt hurt so bad i would be your igor 1 Quote Link to comment
yello620 Posted October 19, 2009 Author Report Share Posted October 19, 2009 Still fighting with starter clearance problems.:mad: Does anybody know if the bellhousing on the VG automatic transmissions will interchange between the two different styles of starters? Basically i think that i can make the other style starter work. I need a z31 style mounting, and i am currently working with a m30/z32 style mounting. 1 Quote Link to comment

Is your starter hitting the frame or the crossmember? 1 Quote Link to comment
yello620 Posted October 24, 2009 Author Report Share Posted October 24, 2009 Actually the starter is hitting the torsion bar.:mad: I know, i know, just put airbags or coilovers in it and be done.:D That is an option, but not what i want to do at this time. Also discovered tonight that i do not have enough hood clearance to run the Pathfinder intake manifold, so i am now searching for a 200sx manifold and a different bellhousing for the transmission. 1 Quote Link to comment
bonvo Posted October 24, 2009 Report Share Posted October 24, 2009 so we have discovered that you need ot run better suspension to clear the starter and the more plentiful donors for the motor to clear the hood so far im not seeing an issue here 1 Quote Link to comment
fastdadd Posted October 24, 2009 Report Share Posted October 24, 2009 i know it is not what you want but will a manual trans mount the starter any different.....for those that still like shifters now would be the time to find out 1 Quote Link to comment
yello620 Posted October 24, 2009 Author Report Share Posted October 24, 2009 I would be ok with a test fit of one if i had a manual trans to test, actually i would like one to test. If i can make all of this work well, then i might make a few extra sets of mounts.:D 1 Quote Link to comment
Skib Posted October 24, 2009 Report Share Posted October 24, 2009 sooooo.... is it done yet :fu: 1 Quote Link to comment
fastdadd Posted October 24, 2009 Report Share Posted October 24, 2009 if you can make it work and after seeing that video of the carbed 510 vg i will be on the hunt for one 1 Quote Link to comment
lynchfourtwenty Posted October 28, 2009 Report Share Posted October 28, 2009 whats with the autotragic.. go 5spd mang! heh :fu: lookin good bro 1 Quote Link to comment
slodat Posted October 28, 2009 Report Share Posted October 28, 2009 He doesn't want to have to shift all the time - back problems. Thus the auto is a good choice and the VG is powerful enough to make it fun to drive. Jason, what is your engine/trans out of? Have you looked at a Z31 automatic? Also, in order to use the Pathfinder upper plenum in a 510, most guys have had to mill it down a little to get it to sit lower in the front at the slope of the hood. You may be able to do the same. Jeff Kline has been known to do such a thing. 1 Quote Link to comment
yello620 Posted October 28, 2009 Author Report Share Posted October 28, 2009 Steve, the Z31 auto trans is exactly what i am looking for, however i think that the 200sx auto and the 2wd d21 trans would also work. I am also looking for a 5spd to mock up.:D This engine and trans came for a Infiniti M30. The Pathfinder intake clearance problem might be able to be solved by the milling of the intake like the 510 guys do, but it would still be very tight. I would like to get a transmission/starter combination that will fit, then start building a oil pan to see if i can lower the motor in the chassis any at all. Right now i have the crank centerline matched to an L-series. anybody have a Z31 auto or a z31 5spd i could borrow?:D Also watching for a complete donor car to come up, super cheap, preferably a 200sx. 1 Quote Link to comment
