drastic520 Posted January 7, 2008 Report Share Posted January 7, 2008 After messing with this J13 and knowing theres no way of making it faster and playing around with a ka24e, i came across the deal of deals. while doing some researching for my buddy, i saw some dattos with rotary motors and was hooked. found 2 running motors but at pickup i found out one had blown so i ended up taking the ugliest car but had the best motor. so here we go again! Mad Cow goes rotary power. its a 12a from an 82 rx7. the car even had working a/c so i took it out. hopefully i can make it fit the truck. wish me luck. one thing is for sure, these motors are the easiest things to work with! in the donor car... setting up for the heart transplant... on its way out... out of the car... about 3 hours and that was working alone. still has all the emissions crap on but soon will be all out!!!!

fisch Posted January 7, 2008 Report Share Posted January 7, 2008 Cool Drastic! Are these motors really that easy to work on? There is a 74 Mazda REPU truck with a 13A and some sort of air dam sticking out of the hood for sale by me. But I wondered how hard rotaries were to work on asI've not researched it, and I am still learning L motors! I've read the REPU's were the fastest minitrucks. It is a sweet lil rig!

drastic520 Posted January 7, 2008 Author Report Share Posted January 7, 2008 man thats one RARE truck! they came with a 13b. the motors are super simple but can get expensive when rebuild time comes. but reliability is great. a few of my friends have always had them in their cars. few toyota starlets and dattos too. hey how much they want for that truck? bet you havent seen any at the truck shows huh???? last one i saw was for sale here in fl and it was 10k.

fisch Posted January 7, 2008 Report Share Posted January 7, 2008 You don't even want to know ow much this thing is, Only $1800! It is killing me not to go get it, but christmas drained the coffers, and the wife doesn't think we need more than one truck. AAAARGH! I am even trying to talk my Dad into it for himself. But of course, being the great son I am, I can store it here if he wants!! Alas I fear yet another cool vehicle is going to slip through my fingers... Quote Link to comment

Bleach Posted January 7, 2008 Report Share Posted January 7, 2008 Nice swap! you're quick. but... RX-7 = Reliable??? :confused: Quote Link to comment
drastic520 Posted January 7, 2008 Author Report Share Posted January 7, 2008 lol.... thats why im stickin to the early 12a. Quote Link to comment
LAYEDOUTB2K Posted January 7, 2008 Report Share Posted January 7, 2008 good luck with the swap, ive always liked rotaries. tomorrow im pickin up a 12a for my mazda that i just bought. Quote Link to comment
Bleach Posted January 7, 2008 Report Share Posted January 7, 2008 I hope it works out for you. I don't know much about them, but I just didnt' hear good things in general. Except for Tdaaj. He had a rotory truck. (old one of course) he loved it. Quote Link to comment
drastic520 Posted January 8, 2008 Author Report Share Posted January 8, 2008 thanks layed.. i dunno what took me so long to think of it. thanks bleach. ill take detailed pics and keep everyone posted.... Quote Link to comment
shane_lxi Posted January 8, 2008 Report Share Posted January 8, 2008 I wouldnt want to work on one, lol. As far as reliabilit, not sure. I have only heard bad things about rotary reliability. They burn oil by design, and dont last as long from what I have heard, I've never owned one though. Not a runner anyway. I had a mazda 929 I was going to transplant a 13b into, but ran out of funding so I sold the car and engine. They are pretty fun to drive though, revs through the roof!! Quote Link to comment
drastic520 Posted January 8, 2008 Author Report Share Posted January 8, 2008 yeah they do burn more oil than a piston motor. its used also for cooling. but they are fun! and with a nice port job u can rev past 8k any time.... Quote Link to comment
irsa76 Posted January 9, 2008 Report Share Posted January 9, 2008 Well it's not like you will be using it to commute everyday in peak hour is it? Rotaries have come a LOOOOOOOOOOOOOONG way over the years. There's a couple of 720s around here with 13BT conversions. Go like stink, but can't pull a load worth a damm I heard. Quote Link to comment
drastic520 Posted January 9, 2008 Author Report Share Posted January 9, 2008 no peak drivin for me. just weekends and a few donuts and figure 8s once in a while..... Quote Link to comment
garryk6 Posted January 10, 2008 Report Share Posted January 10, 2008 There used to be a 1964 L320 in the North LA areas that had a 13b with 5spd and the stock 320 gears and brakes, with the Top made into a convertible hard top. It was extremely fast, but did not stop as well, needed beebani's disc kit... The L320 was smaller and lighter than the 520, but my 66 L520 was decently quick with 3.89 gears and a hopped up J-13, but it was just my daily driver, needed reliability... Good luck on the swap, it will definitely fit, but you will want discs, and you may want to get some training on repairing rotaries, as there are not many rotary shops out there any more. Good Luck, Garry K in Kodiak, AK My Baby!!! Quote Link to comment
drastic520 Posted January 10, 2008 Author Report Share Posted January 10, 2008 oh yeah stopping will be an issue. thats my next mission. i will be using his brackets for sure. i already bought the rotors needed. i think i saw the brackets on ebay but not sure if they were his. my buddy is also doing the rotary swap on his 320 so we will be havin some fun out there in the streets. i have someone in the family who has lots of knowledge on the rotaries since hes been building them for street/strip all his life. only reason why i did it cuz you are right about there not being many mechs out there. by the way the excursion is TIGHT!!!!!!!

ppeters914 Posted January 10, 2008 Report Share Posted January 10, 2008 all-REET! GarryK is back online! :thumbsup: Quote Link to comment
drastic520 Posted January 11, 2008 Author Report Share Posted January 11, 2008 here is a bit of an update. the rotary has been stripped of all emissions junk and removed stock intake, carb and exhaust manifold. just waiting for my racing beat stuff to come in. also started the removal of the J13. UP FOR SALE!!!! GONE!!!!!!! here they are side by side. almost the same size. the rotary block is shorter but the tranny is longer by 2 or 3 inches. little mods needed to make it fit i think. more to come soon!!!!!

garryk6 Posted January 11, 2008 Report Share Posted January 11, 2008 Lookin good on the 520! I miss being able to work on my Datsun's, so all I get to work on these days in the Excursion. Had to temporarily leave my Datsuns in WA state, since my retirement from the Navy and move to Kodiak Alaska. Thanks for the comments on the Excursion, it has the Harley edition grill and headlights with F-350 springs and leveling kit (Approximately 3.5 inches of over all lift) Much better ride, and 33x13x20 rims and tires (for the summer of course) For the winter I am running 33x10x16's on the stock rims studded, as it is only in the teens for highs right now, but very sunny, just very cold. I miss the days in Sunny San Diego where one of the pics of my 66 520 was taken, alot easier to work on cars outside!! Keep up on the project pictures, as it keeps me wanting to move up the 520 and the two NL320's... Just need a garage now....
