Mrjreezy Posted September 23, 2016 Report Share Posted September 23, 2016 Hey all, I'm new here to the forum. Last weekend I picked up a 1979 620 that is in pretty rough condition. The paint looks like old spray paint. There's a garden in the engine bay, and it was hardly a rolling shell with the ubolts dragging the ground. Now on a sidenote, when it comes to cars I'm not new to the turbo world. I've had tons of dsm's, worked on countless 240'a and currently drive a big turbo SRT-4 and and my baby which is a 91 miata that has been my biggest project for the last 5 years. So my intentions for buying the 620 is to put a KA in that is built for boost, which I have already found and bought and just waiting for my buddy to bring it to me. Pics of the truck and engine will be posted soon. 1 Quote Link to comment
Jester Posted September 23, 2016 Report Share Posted September 23, 2016 Cool. Welcome to Ratsun. Bring on the pics! This guy has KA engine mounts for the 620. 1 Quote Link to comment
Mrjreezy Posted September 23, 2016 Author Report Share Posted September 23, 2016 To be honest 2eDeYe is a big reason why I joined the forum. I found a thread about him selling the KA mounts and then started lurking on the entire forum. I love posting/reading build threads and I always rely on forums for information, so why not join? Thanks for the welcome! To kick things off here are some pics of my current cars My 91 turbo miata. Still needs to be tuned and have the maf removed. It's been a long haul. My daily SRT4 And now for the 620 Last but not least, the freshly built KA going in it Machine work has been done .020 Pistons 248/248 hot cam swap polished and balanced crank new acl bearings arp head studs felpro headgasket The turbo I run will most likely be a t28 of some sort. Possibly a disco potato if I save a bit more and find one at a good price. Or I may stick with a t25 just for a safe relaible power level. I have no official idea at this point. 3 Quote Link to comment

Mrjreezy Posted September 28, 2016 Author Report Share Posted September 28, 2016 It's a Chia Pet for sure haha. That has a nice ring to it. Thanks for the welcomes! Today I went and picked up the engine and got more than what I expected from the guy for no extra cash. He was a real cool guy. 2 Quote Link to comment
Mrjreezy Posted September 28, 2016 Author Report Share Posted September 28, 2016 It's a KA with a fresh rebuild and no miles. ARP headstuds Felpro headgasket .20 over 248/248 cams 550cc injectors Z32 man Isis turbo manifold 5speed trans with new throw out bearing and short throw shifter 3 row rad Intercooler with some piping (it's pretty huge though) the "white bunny" clutch setup Engine harness And a rom tuned ecu I just need to get a t25 or t28 and some mounts from ]2eDeYe to complete the setup. The plan now is to save for brake upgrades before anything else. It'll be awhile for that. But I'll probably clean the gas tank and stuff in the meantime. I'll also have to build a fuse box. I saw a thread on here how to do it, I just need to find it again. 1 Quote Link to comment

Mrjreezy Posted September 29, 2016 Author Report Share Posted September 29, 2016 I hope it'll all turn out awesome in the end. This is my first "truck" so I really want it to be a decent build. Thanks for reading along so far guys. 2 Quote Link to comment

Mrjreezy Posted October 4, 2016 Author Report Share Posted October 4, 2016 A few days ago I ordered the mounts for ]2eDeYe and they should be here thursday. Today I got bored and realized how much I hated this gold spray painted engine bay. So I grabbed a couple of cans of black spray paint and decided to paint everything to make it look at least a little more decent. Before After At least it looks a little better. I will paint the truck, but I don't care too much about the engine bay. As long as it looks decent. I did notice it had some front end damage that may be a concern later on. The bumper brace is bent up and the core support looks off just a little bit. 2 Quote Link to comment

Volition77 Posted October 5, 2016 Report Share Posted October 5, 2016 Mrhreezy, Nice truck and welcome. I have a 73 I'm doing the same thing too...I wanted to ask if you figured out how to get around the turbo manifold getting in the way of the brake booster? I'm stuck there and looking at a top mount with a spacer to move the turbo out of the way...good luck! Quote Link to comment
Volition77 Posted October 5, 2016 Report Share Posted October 5, 2016 I might look into this... http://www.chasebays.com/chase-bays-brake-booster-eliminator-honda-nissan-mazda-mitsubishi-ae86/ Quote Link to comment

Looking at the bay I figured it would be though. You answered that question. I'll try to get the engine in, but honestly deleting the brake booster is probably the way I'm going to go. The pedal feel won't be as good, and you'll have to push down harder, but at least the bay will look clean I suppose.. Quote Link to comment
Mrjreezy Posted October 6, 2016 Author Report Share Posted October 6, 2016 Oh and the brackets came in mail today. I'm ecstatic about this. 2eDeYe shipped them quick. 1 Quote Link to comment

The pedal feel won't be as good, and you'll have to push down harder, but at least the bay will look clean I suppose.. If you pick the right parts your brakes will have feedback like you have never had. A stiff pedal is not because of the lack of power assist but rather the wrong size bores. Look at the tilton Model 74. They can be bolted together for added rigidity. You'll need two. One for the front and one for the back. Quote Link to comment
Mrjreezy Posted October 6, 2016 Author Report Share Posted October 6, 2016 http://tiltonracing.com/product/74-series-master-cylinder-kits/ Thanks for the info. That's almost an easy $200 right there. I guess its back to ramen.. (brake parts are worth it I know. I don't want to hurt someone else or myself.) Did you have to make new brake lines as well? Also what bores are needed?

Mrjreezy Posted November 8, 2016 Author Report Share Posted November 8, 2016 So I haven't gotten around to work on the truck as much as I've wanted. I do have a few updates. I found some one stage paint that I liked and decide to go ahead and paint the truck. I got rid of the surface rust using a wire wheel. I didn't notice how many dents this thing had until after I painted it. Kind of breaks my heart, but oh well this is just going to be a fun beater. And I painted the entire frame black with stop rust paint. 4 Quote Link to comment
Mrjreezy Posted February 7, 2017 Author Report Share Posted February 7, 2017 I've been gone for awhile but I haven't seen stopped working on the truck. We finally got the engine in recently. Flipped the centerlink, and swap on the mounts and dropped it right in with the trans. It wasn't too much of a pain at all either. 3 Quote Link to comment
Mrjreezy Posted February 7, 2017 Author Report Share Posted February 7, 2017 It doesn't look like I can use my Isis manifold. It's up real close against the steering column and I doubt the turbo is going to fit. Keeping this a cheapish build I have already gotten a top mount log manifold to replace it. It will at least work. I'm going to try and fit it on the bottom mount first at least. My turbo is only a t25/28 hybrid. It could work. But doubtful. 2 Quote Link to comment
Mrjreezy Posted February 7, 2017 Author Report Share Posted February 7, 2017 The truck only came with one shock that wasn't in too good of shape so I bought some replacements and put them on. They're from AutoZone. Hijackers. So I can at least fill them up with air to stiffen the ride which might come in handy. These aren't the hoses' permanent resting places. After I get the bed on I'll do better routing. 1 Quote Link to comment
