Well I finally have gotten some work done on the go kart, after what seems like years of having it off to the side I pulled it down and started on the rear end.  I mocked some stuff up and ended up liking it.  The very corner of the triangle will have another brace going up to the rollbar to support it some more.  I had my buddy who weighs about as much as the engine stand on the skidplate and I stood about where I sit.  When we jumped together on the softest setting it almost bottomed out and when we put it on close to the hardest setting it hardly moved at all so I'd call that successful!  It also has a little bit of height adjusability which is what the washers are for, I can add of subtract 2 and raise and lower the kart a tiny bit for small adjustments.




Oh yeah, and I got an LS3.

So I've been putting off doing any updates on this just because I wanted to actually have something to report but in all honesty I've hardly had any progress other than getting some ideas for how the hell I'm gonna do front brakes and the rear swing arm, the second part shouldn't be too hard.

The main reason for nothing happening is because of school and work, I thought winter quarter was pretty tough but my spring quarter made it look like child's play.  I decided to skip intro to statics (not statistics, that's super easy) because it used to be that they covered about 2 or 2.5 chapters in intro and did a long review in just normal statics.  Turns out now they cover 4.5-5 chapters in intro to statics so when I came into statics I was about 4.5 chapter behind everyone else.  Definitely never skipping a quarter of something again!

However during spring break I did get a bit of work done on my cbr600 which is getting sold soon.  I got a bit of the body work done on the fairings and painted two of them.  I did white cause that seems to sell well at the moment and since it's riding season hopefully I can catch a pretty good price for the bike.  As for the other bike, the gs550, that thing has been the absolute bane of my existence for two years and it's probably getting sold in non-riding condition.  The cbr should make up for the loss I take on that bike and honestly never having to see that bike in our garage again is worth a couple hundred dollars haha.


The miata project is still basically in the process of buying lots and lots of parts.  I've been doing research on doing this swap for over a year now, and other than electrical it's pretty much all planned out.  A couple months ago a ls1 popped up on ls1tech for a good price and honestly I was getting kind of impatient so I jumped on it.  It had just over 70k on it, was a 2001 and had a 85mm TB, all the accessories, the only thing missing was the computer and wiring for $1700.  I decided to buy it but paypal had other plans for me, they decided to flag my account and take forever working out the problems.  The kicker was they didn't even flag the 1700, it was the extra 50 I added for the paypal fees later that they flagged.  Anyway the guy got impatient and sold it to someone locally.  I was pretty bummed but it wasn't that big of a deal.

Then about a month or two ago a t56 popped up on craigslist for 1000, had under 70k on it and had a 5.0 short shifter on it.  I jumped on that faster than hell and picked it up the next morning.

As for progress on the go kart, I got the whole rear end ground off so that there's no evidence that I ever decided to weld my swing-arm to the frame.  The deal with my dad is I have to get rid of both of the bikes before I do any major work on the go kart, so that doesn't help much with getting work done haha.  I attached the pics of the new swing arm which I'm really pumped that I bought, was an awesome deal and makes my life a ton easier!  I also have a gsxr750 monoshock lying around my garage that I think I'll use to give it a tiny bit of travel but not too much.


My idea for the front brakes may be a really really horrible idea but I ain't about to buy an actual front brake kit for go karts, those things are freaking expensive!  Basically the idea is to make my own spindles (not hard) that will allow my to push the front wheels out a lot farther that they already are (a couple inches more than they currently are).  Not only will this allow me to drop the front end an inch or two by making them drop spindles this will allow me to stick the rotors and calipers from the gsxr750 I mentioned before onto the front end.  The picture is the size of the rotor compared to the size of the wheel.  The part I'm most worried about is when there's weight on the front end and the tires flex a little, I don't want to be grinding rotors on the pavement haha.  We'll see what happens, maybe I'll try to pick up some rear rotors, that would probably work better.



I also am thinking maybe just do a roll bar on the go kart instead of a full cage, a cage is going to make it extremely hard to take the engine out which is something that I'm sure I'll have to do again sometime.  Oh and the wood that you see under some of the pictures is the platform we built to put the karmann ghia under, now we're using the volume of the garage instead of just the surface area!

The last thing that's happened around here is that we got a beater truck for hauling our boat up and down the hill to the boat ramp over in eastern WA.  We have a really small spot of land with a trailer on it that's nice to go to but when we use the boat we have to take the diesel over there to haul it up and down the hill.  This truck will hopefully save some money in the long run and some trouble of hauling the 250 over instead of the miata or something.  Also I took the hardtop off the miata finally, it's definitely summer time!  That just about sums up the last few months, lots of work, even more school and very minimal fun time to work on stuff.  At least I'm only taking calc 3 for summer quarter so I should have a ton more time!

Oh and one last thing I guess, by the end of the month I should have enough saved for an ls3 crate engine, if no good deals pop up then I'm gonna go big I guess.  While it's not the most cost efficient option (by far), it's going to make the car exactly what I want and that's what's important, right?  I don't want to rush this build like I did with the go kart, if I hadn't rushed the go kart I wouldn't be writing about all the stuff that needs to be done because I would have done it in the first place.

It's been forever since I posted anything on here and I don't really have a ton to report.  Even during winter break I was pretty busy with work but I got quite a bit of grinding done on the frame.  I got quite a few of the welds ground down and about half of the rear welds from the swingarm taken off.  However my dad and I decided it was time to add more surface area to the garage so we built a shelf over my mom's karmann ghia so that I could work on my go kart and keep my motorcycles inside along with her car.  I also bought a real swingarm off a raptor 660 since I was tired of trying to screw around with my current one and the damn chain tensioners.  It had a broken bolt in the tensioner so it was quite a bit cheaper than the other ones listed and I figured I'd give it a shot.  I'm not exactly sure how they broke the bolt but I got it out with a pair of pliers, no heat or any other tricks, just a normal pair of pliers.  That was a good day!

After I got that I started looking at how my suspension's gonna work and I think I may lower the kart a little with the new swingarm and build my own spindles to drop the front another 1.5".  I'd like to have the kart back together by May but I'm pretty sure that's not gonna happen.  Either way, it's fun working on it as often as I can and getting the chance to be back out in the garage again.

Other than that I got my timing belt done on my Miata and received my v8r frame for the swap coming up.  I decided that since I was making quite a bit more at my new job that I could take a bigger hit to my budget and have come to the conclusion that a 376 ci engine would be best for the Miata.  Although it forces me to buy more expensive axles (among other things) and is going to be more expensive than just an ls1 I think I'll be happier with it in the long run.  I'm planning on getting a l92 long block and going from there, I just wish I had been checking ls1tech because a couple weeks ago cause one went for 1375 plus shipping and I had that on me.  I'm sure I can catch a deal in the next few weeks though. 

This has kind of turned into a section on my next project but seeing as how I don't have a ton of progress on my current one I figure I might as well write something interesting.  After I work the kinks out of the Miata I plan on rebuilding the engine to ls3 specs and go through the heads since my total plan for the Miata is to hit the 500whp mark.

Seems that the build is going much slower than I had originally thought.  Turns out going to school full time and working close to full time pretty much limits your schedule to school and work.  Not really much to post about since I haven't gotten much done but I did get some bushings ordered and bored out a piece of tubing for about two hours so that they would fit inside.  No pun intended, I was bored out of my mind, it was a very slow process but worth it.

So I'm not sure anyone is reading this but whatever.  Over the weekend I finally got to dig in to the kart and take it all back apart again.  The first day I focused on getting all the wiring off the engine and getting it ready to pull the next day.  It was a pretty depressing process taking everything that I had worked so hard on apart but it'll be worth it.

We mostly just had to get it out of the way so we could build a structure on top of one of our cars so that I could store both two of my motorcycles in the garage along with the car.  I think this project's funding may be getting delayed a tiny bit as I'm also planning on putting an ls1 in my Miata in about two years and I may have the chance to get one that needs rebuilding for pretty cheap.  I'll see how that goes and spend accordingly, thankfully there's not a ton to buy since I already have all the stuff needed for a rear suspension and most the stuff for front brakes.  I'd like to get started on the suspension in the next couple weeks since re-aligning the rear end is gonna be the hardest part but here's what I'm left with right now.

So this is what I'm working with.  I built it for my senior project and since I was running very low on time many things were thrown together faster than I would have liked.  The biggest thing is the solid swing-arm.  It was originally supposed to have a rear suspension but I ran out of time and had to weld it to the rear of the go kart.  Obviously this is neither safe or practical.  It extends the go kart about another foot and does nothing other than scare me because I'm afraid it's going to snap.  So after I got everything working right I decided to rebuild the rear end and tidy up all of the kart. 


The big things on the list are:
-Suspension (cut off solid swing-arm, make it a real swing arm)
-Front brakes
-Convert t595 rotors to four bolt so I can use them on the axle
-Longer axle (5 and 5/8")
-Wider hubs (3 and 1/2")
-Push-pull cable shifter
-Clutch behind steering wheel
-Hopefully a rollcage
-Re-weld some things
-Grind all weld
-Paint!

I want to get it out and running next year by riding season to give some time for trouble shooting the little gremlins that are sure to appear after the rebuild and then get it out to the track and hopefully the drag strip to see how she handles the 1/8th and possibly the 1/4 if I can get them to let me run it.
