fisch Posted March 1, 2009 Report Share Posted March 1, 2009 A V6 turbo IRS 521.....BAMF. SAWEET! Woah dude this is ambitiously awesome! I've only a couple other Nissan V6's in a 521. Document everything! This is a cool one that still looks stock. http://forum.ratsun.net/showthread.php?t=2584&highlight=vg30+521 Quote Link to comment
Hyphy Posted March 1, 2009 Author Report Share Posted March 1, 2009 Its unfortunate he didnt have better documentation. Itd probly help me do mine alot if he did. Tho the few pics he did have are still helpful. As this motor is comin out of a z car, im hoping the oil pan clearance will be better, but Itll be hard to tell until I get to mockin it up. The steering was always a concern when i decided to do this. The solid, one piece, column makes it a pain. The steering being directly below the engine worries me as it was also a poin of impact when pulling the L series out with trans. Tho i never successfully got the L out while the trans was still attached anyway. I know i want to ditch the torsion bars, so theres some clearance there. Tho i still havent tackled the steering. A rack and pinion would be ideal, especially if it works well witht he stock Z car components. Regarding the rear end....I am seriously leaning towards pulling the rear subframe from the Z to maintain gearing and LSD while gaining an independant suspension. Quote Link to comment
Jester Posted March 1, 2009 Report Share Posted March 1, 2009 If your going to use the Z rearend, why not the front as well? I had asked about this setup once and found it to be too wide. How about adding some 510 box flairs in front and some custome made ones in back? Quote Link to comment
bonvo Posted March 1, 2009 Report Share Posted March 1, 2009 i like the subframe transfer idea alot do both of them and run some boso flares :D Quote Link to comment
Hyphy Posted March 1, 2009 Author Report Share Posted March 1, 2009 The rear subframe unbolts from the unibody car...I doubt the front does the same.... The subframe swap to an IRS'd rear isnt set in stone. I have to do some measuring and figure how Id fab it. Its a more complicated task. I could bag this truck in my sleep so to speak, but swappin this IRS in is new to me. Taking some other truck parts and a set of Beebani's custom uppers gets me balljoints and adding coilovers at that point isnt difficult. Tryin to find a rear end that works is a lil trickier. Any non 521 rear I try would have to be shortened. Quote Link to comment

Hyphy Posted March 1, 2009 Author Report Share Posted March 1, 2009 an interesting setup indeed. Hope it works out great for him. We both know the 300z is a different beast entirely tho.... somehow i shoulda know tho that a miata would wind up being a pretty much perfect fit. Quote Link to comment
datzenmike Posted March 1, 2009 Report Share Posted March 1, 2009 (edited) The earliest Pathfinder was in '87 and did have Z24i motors but rare I think as a stronger VG would work better. This could be a Z24, but definitely is NOT a Z24i. The Z24 like all Z series motors will easily fit the 521 and 620 trucks by using the Z series motor mounts. No cutting or welding required unless you have the older 520 with the J13 motor. Your 521 stock tranny will have a ribbed case with a removable bottom pan and flange output. The dogleg will be the same length, no ribs on the case, no bottom pan, will have a front and rear case half sandwiching a 1" steel adapter plate in the middle and have a flange output. BOTH are about 26" long. .... just read that you can't remove the driveshaft.... this makes it not the FS5W63 dogleg. I find it odd the tranny tunnel was cut which indicates a long tail tranny was installed. Can't think of many flange output long tails. POST A PICTURE OF IT! Like a lot of projects... this started out simple enough. Now it's VG30ET with IRS?? Good luck mounting a turbo VG, those torsion bars and steering have to go. You aren't seriously thinking of bagging an IRS rear are you?? Edited March 1, 2009 by datzenmike Quote Link to comment
72240z Posted March 1, 2009 Report Share Posted March 1, 2009 (edited) I know everyone, even wiki and other forums say the 1st gen pathy came z24 but I have never seen one stateside. Must be super super rare, I have doubts though. I would like to see/drive one in person to compare. All that aside though from the pics wouldn't it make more sense that it be a 720? The rad support and what not sure looks it. Edited March 1, 2009 by 72240z Quote Link to comment
datzenmike Posted March 1, 2009 Report Share Posted March 1, 2009 (edited) Ha ha.. you see what you want to see right?? He said it was Path and they only had Z24i. I could tell it wasn't a Z24i so I ASSumed it was swapped. Besides, I have never seen one either, but yeah now it looks more like a 720 than a Path. The Z24i is a throttle body injection. The fastest way to tell it from a Z engine, is that the throttle body uses two wing nuts to hold the air filter on. All other Z engines with carbs use only one. The 620 doesn't use any wing nuts.

72240z Posted March 1, 2009 Report Share Posted March 1, 2009 Wasn't really a knock on what you had said Mike just what I thought when I saw it after skimming through the thread. Anyone's guess at this point lol. I'm going to make a mental note about the air cleaners. Far too often I'm guessing i or not. Quote Link to comment
datzenmike Posted March 1, 2009 Report Share Posted March 1, 2009 No probs, I ment I saw what I wanted to see. It's a bitch when you assume. Usually when things don't add up later you go back and notice other things too. The very late '86.5 720s actually had Z24i in them too. Maybe a month or so before the switch over to the new D-21 Hardbody. Manuals including the '86 FSM do not mention it. There is a small FSM addendum for the '86 that covers ONLY the EFI section. Extremely rare and collectible. Considered the Holy Grail to a 720 owner. :lol: Quote Link to comment
Hyphy Posted March 1, 2009 Author Report Share Posted March 1, 2009 (edited) yea...never got back around to fillin in the blanks on here... After some research.. turns out it is a 720 and it sits in my garage. I need to get rid of it and fast. The 300zx is gonna need that spot very soon. It is a Z24 (not i) and a 5speed. Pass side front half shaft is shot at the hub/cv joint. The old motor from the 521 is a L18 with a W58 head and a dogleg. It has the 1" 'spacer'. No idea why the trans tunnel was cut. Could have been from a swap even before this one...who knows. The truck had been involved in a flood that got to about halfway up the door panel. Didnt work after that and didnt bother to mess with it. After pullin the motor...the cluth/flywheel..all that .. was rusted...orange water form the water pump and so on. The comment about baggin wasnt to ensue that i was plannin on baggin it, but that I could. Skill/talent wise. I used to own a s10 that over the time i owned it, had redone everything i paid to have done in the first place. When it comes to baggin trucks...I know what im doing. Baggin and IRS is only for the cool factor of negative camber in the rear IMO. Id honestly have no problem keeping a solid axle in the rear either. I just hapn to have a donor z car now so was gonna run with that. Plus, bagged or not, IRS is definitely a plus both for performance and cool factor. /edit.. Any thoughts on the steering? Rack and pinion from the z was gonna be the first place i started..once i get it back to my place. Due to the weather and a full garage, im havin a local mechanic shop pull the motor so I can get the rebuild started. Would a miata rack work?? lol Edited March 1, 2009 by Hyphy Quote Link to comment
bonvo Posted March 2, 2009 Report Share Posted March 2, 2009 i honistly like the irs idea you have here narrow it a little and run some mild flares and call it good Quote Link to comment

bonvo Posted March 6, 2009 Report Share Posted March 6, 2009 hey bro this thread my help you out http://forum.ratsun.net/showthread.php?t=6005 :D Quote Link to comment
Hyphy Posted March 9, 2009 Author Report Share Posted March 9, 2009 Updates disassembled motor for rebuild. The pieces that will be cleaned and possibly ported (if theres funds left) The bread and butter :D Nearly everything below the valve covers was loaded with grime and oil. The alternator was literally covered in oil. No surprise being that it sits underneath the oil filter. I brought those pieces back and cleaned em up. I figure ill need to buy new mount isolators to keep the ride smooth. Tho some have said this motor is relatively smooth as is and the VG site that sells 510 swap parts sells thier own solid mounts, I may reconsider this. Starter- The mount casting broke during transport. The clutch - slipped really bad during the test drive when i bought the vehicle. When i took it apart, it looked like the pressure plate in the clutch had developed some hot spots. It may not have been broken in properly when the PO put it in. Other things will of course arise, but for now that seems to be all aside from the parts for a rebuild. The turbo seems to be fine, tho without a boost gauge on before hand..its hard to tell. No numbers yet from the shop thats rebuilding it so no idea what if any money will be left for upgrades or an ETA. I should hear back on monday. Quote Link to comment
Hyphy Posted March 9, 2009 Author Report Share Posted March 9, 2009 At this rate I should probly suggest that this get moved to the projects section and be titled 'VG30ET 521' Quote Link to comment
bonvo Posted March 9, 2009 Report Share Posted March 9, 2009 what shop are you taking it to bro is it one in town or a place out of sac? Quote Link to comment
Hyphy Posted March 9, 2009 Author Report Share Posted March 9, 2009 California Street Machine in suisun. I know the owner. The luxury of runnin a sign shop, I know alot of business owners in the area. :D He was actually in there saturday workin on a 600cu.in. alcohol motor. 3k horse i think he said, may have been BS tho... Quote Link to comment
72240z Posted March 9, 2009 Report Share Posted March 9, 2009 It sounds a little bullshitty to me. I have seen 8.2 hemis blown on strait alc making 1500ish hp, under decent boost. Either way though a 600cu rat presumably running super high comp on alc is making buku hp lol. No doubt about that...... Quote Link to comment
fisch Posted March 9, 2009 Report Share Posted March 9, 2009 At this rate I should probly suggest that this get moved to the projects section and be titled 'VG30ET 521' Done and done Hyphy. I am really psyched about this swap! Quote Link to comment
Hyphy Posted March 9, 2009 Author Report Share Posted March 9, 2009 I went pokin around the local PnP found a few s13's a few 300z's no miatas tho. Im thinkin I may not do the IRS setup. Which means Id have to find a solid axle. Probly get it and the axle shafts shrotened, make sure it has LSD and the right bolt pattern...grrrr.....I could wait on doing the rear in general. But i have a feeling if I do, when i got to test drive itll fail. S14/13 rears would be nice, Ill have to go diggin around the Rancho yards at some point. Quote Link to comment
bonvo Posted March 9, 2009 Report Share Posted March 9, 2009 hmmm what about a 510 rear? i know its not the best but i know where you can get one for cheap and it will be the right width Quote Link to comment
