datsunfreak Posted September 10, 2012 Report Share Posted September 10, 2012 How 'bout this then? Quote Link to comment
Dawa Posted October 4, 2012 Author Report Share Posted October 4, 2012 ^ that would be ideal. a little lower than that even, if i can get by without scraping. (p.s. i saw when you posted that but i didnt want to bump my thread without any updates.) anyways, i took a little break from workin on my truck after i went crazy buying parts out of control. then i was in seattle for 9 days, and now im focusing on repairing my sc300 and 240sx. i finally got everything together for my front disc brake conversion, which ill probably accomplish this weekend, with an update and how to.

Dawa Posted November 7, 2012 Author Report Share Posted November 7, 2012 finally got the engine to hop sing's machine shop here in sd. they mic'ed the block and pistons and discovered that the bore is 20-22 over on stock sized pistons. regular pistons and a larger bore equates to piston slap, which i feel is what mightve led to the previous owner's misdiagnosis of "spun bearing"? i say this because the crank was mic'ed and does not show evidence of a spun bearing. i found .30 over l20 pistons on rock auto (beck/arnley brand, $19 each because theyre on closeout, bought 4 of 7!) having the block decked, hot tanked, and head looked at as well. once the pistons get in theyll look at the rods. im excited Quote Link to comment
Dawa Posted November 29, 2012 Author Report Share Posted November 29, 2012 the engine is complete, ready for me to pick it up from the machine shop. EXHAUST: lowering the truck 4.5"+ took it's toll on the exhaust. the lowest part of the exhaust was where it was routed UNDER the rail that the anchor arms for the torsion bars are located. at this location the exhaust was approximately 2.5" or so from the ground. i had to take speed bump side ways which did help but it would sometimes still scrape. eventually something has to give and the exhaust severed completey at the tail end of the ypipe (where 2 become one.) i installed a few temp fixes over the months but finally brought it to Ed Hanson's muffler shop in spring valley. Ed has been in the exhaust business for a long time. he teaches exhaust theory, knows his shit, etc etc i mentioned that the least i wanna do is fix the 'leak' and at most i want to enlarge the y (from 1 5/8") and install a new exhaust. he gave me a quote of $350 to replace the entire exhaust from the y back (w 2" aluminized pipe) & i told em to start work! out with the out: Quote Link to comment
Dawa Posted November 29, 2012 Author Report Share Posted November 29, 2012 enlarged y pipe mock up and welded up: from y to trans mount now, for photos of the 2" exhaust going OVER the the rail that the anchor arms are located. i didnt think they could do it but they did! so then i was afraid of metal to metal but there is none, so no added vibration or added heat transfer. close up of one (ouf of 4) of the solid hangers. MUFFLER the shop is awesome in that they route & weld the system up to where the muffler would go, then let you start up & rev the car while they hold up different mufflers so you can get a feel for what your new ehxaust will sound like. truck previously had a glass pack style. i wanted quiet, so i went with this one, well it turns out its TOO quiet! ill eventually go back and have em chop it off and add something just a tad quiet. as you can see in the photo of the hanger, the entire exhaust is ABOVE the frame. itll never scrape again! i do feel that a 2" exhaust on an unmodded 1.6 is a bit much. i feel like ive lost high end ,specifically 4k to 5k on the highway. which i know doesnt make since because the free'er flowing exhausts are supposed to help out at high rpms.... it could be the lack of feedback from the exhaust since its too quiet (aka all in my head.) it does seem to go from 1k-3k quick enough though (which again doesnt make sense because youd think i would lose low end.) but itll be perfect for when i drop in that 2.0.

Juan Valdez Posted November 30, 2012 Report Share Posted November 30, 2012 I like when you post reviews of local shops. It lights a fire under my ass to get out and work on my truck. The exhaust routing looks really clean, especially those hangers. I'm desperately needing an adjustment of my exhaust since the header flange sits on the bell housing and rattles like mo-fo. I also get RIDICULOUS amounts of heat transfer to my ass in the drivers compartment. I'm sweatin' like a whore in church if I do any extended driving. Quote Link to comment

Very common for a car to seem slower with a quieter exhaust, and feel faster with a loud exhaust. B) Quote Link to comment

datsunfreak Posted November 30, 2012 Report Share Posted November 30, 2012 grand total of $400! i feel like this is a pretty good deal! That would have been $600+ at my local machine shop, so I'd say you did okay! :thumbup: Quote Link to comment
Juan Valdez Posted November 30, 2012 Report Share Posted November 30, 2012 Indeed. I paid close to six bills to Broadway Machine out in Lemon Grove for similar work to my L28et. Looks like you made out well. Quote Link to comment
Farmer Posted November 30, 2012 Report Share Posted November 30, 2012 That's a great price. I paid around 1600 for my engine rebuilt but that was pistons,valve springs, and all the goodies. ButI also had him assemble the whole engine too Quote Link to comment

Reason why inthough it was the bearings was cause there was a large amount of rattle after i reved the motor high one night. checked the timing chain seemed fine and couldnt figure what else was wrong. had a friend look at it And saidnthat was it. Can't wait to see it running again. You coming out to the meet tonight? Quote Link to comment
Dawa Posted December 7, 2012 Author Report Share Posted December 7, 2012 yeah man i hear ya, i woulda never thought that it was the pistons, i probably woulda thought it was knock as well. so the meets are thursdays, i forgot what day aha. id like to make it out but not sure. ill make it out there in a few weeks though Quote Link to comment
socaldatsun Posted December 7, 2012 Report Share Posted December 7, 2012 Let me know if you need a hand droping in the motor :) Quote Link to comment
Dawa Posted December 9, 2012 Author Report Share Posted December 9, 2012 i finally got my mooneyes floormats theyre kinda thin so i just put them atop the other mat i had in there, for now. today i had to replace another starter (under warranty @ oreilly.) the starters keep getting gunked up because of an oil leak, rear main seal im guessin. sold the volk/rays wheels, so ill have a lil bit of $ coming in from that, that way i can buy the lil parts for the engine rebuild and get her in soon. currently on the back burner til the funds come up: -king pin to ball joint upgrade w 2" drop spindles ♥♥♥ -front disc brakes -leaf spring de-arc OR custom springs also had my dude in japan look for some 17" 6 lugs wheels, there just isnt as much selection for 16s as i had thought. if i find a nice set of 17s ill slap em on 245/35s, which will only raise the height by .5" which is perfect! (as well as fill in some fender gap .5" too) 1 Quote Link to comment

Dawa Posted December 18, 2012 Author Report Share Posted December 18, 2012 went out to my car sunday mornin to find this no note or nothin, 'cept for some other vehicle's white paint. didnt see a white vehicle in the area and i was heading up to LA so all i could do was get in the truck and drive. while i was fillin up @ 76 i was lookin at her in dismay and wondered if i could push the dent out from within. well, luckily, just like the hood, the fender metal is thin as hell and it popped out real easy like. it's still noticeable if you scrutinize it, you see the smaller 3 dents, those are sooomewhat still there.
