Congrats on the baby :)

Also good to see this thing making serious power and finally getting wheels to put it down

Glad to see you you can be a dad and still have a little time for cars. I had to look up what a cheetah blaster was. I had an idea it was just to blow air to seat the beads. Pretty simple idea. I bet it cost you half as much to just make one.

Lookin good man! I don't know why, but i seriously feel like this thing needs a FMIC for 20+psi of safe boosting. I know you've made your decision, but it seems like cheap insurance (FMIC + meth = never det!). Anyways, carry on.. :)

Well as far as the front mount goes I now have an IAT gauge I will be hooking up before the car gets driven again. It reads two sensors at the same time I have one placed coming right out of the turbo and the other is right before the throttle body it will be very interesting to one see what my IAT's are and two how much of a difference the methanol makes. It is also always fun to see peoples face when you tell them you are running 20+ psi with no intercooler with a piggy back and no idea what IAT's are most people push it off as I am crazy or stupid mean while I am just feeding it gears lol.

Surely Fae bought those tires used. No way his car was running long enough to wear them down that far. :giggle:

At least he was shooting for glory, instead of the ditch :cry:

Not a fan of those wheels, but to each their own. Your car is still sick. Mount tires and vids NAO!

Well just because you're making lots of power doesn't mean you're not running crazy high AIT's. But I'll eagerly await result

Just in case anyone wanted to know. The transmission will come out with the engine in the car. I know that may sound strange but until this point I have only taken it out with the engine. I was very happy when I dropped it out last night. Only took about 1.5 hrs. and she was on the ground. Now time for a new one.

So I have been thinking about doing this swap ever since I was in an accident that totaled my 1jz mk3 supra I now have a homeless 1jz and a 92 Miata that lacks power I have seen a few times where u said a 1j fits better just wondering how and would a front sump be better than a rear also what all did you have to cut for it to fit in the Miata not sure how to post pics hope this works https://www.miataturbo.net/attachmen...ine=1398216642 https://www.miataturbo.net/attachmen...ine=1398216642 https://www.miataturbo.net/attachmen...ine=1398216642 https://www.miataturbo.net/attachmen...ine=1398216642 https://www.miataturbo.net/attachmen...ine=1398216642

We'll to start with the 1jz is shorter to begin with so that helps a lot. I have a front sump pan on my car and it works a rear sump would prob work better if you use the rear sump and notch the cross member it would work great.

What where the biggest obstiacals you had? I really am considering this swap mainly because the weight the mk3 at 3800 pounds is a boat

I did zero cutting to my firewall and trans tunnel and had to trip the lip off the passenger side frame rail to clear my turbo header so it actually fits pretty good.

I will give you a list of the biggest problems tomorrow when I can write a post on my computer. I'll send you a pm too.

Also my car weights 2800 with me and another person and a hartop lol

Awesome I really appreciate the help. And ya power to weight is a huge factor and 1000 pounds less to haul around will be fun

Ok now on the computer I can write a relevant post.

Things needed to be done to get a 2jz in a miata. I am using a 2jzge with single turbo manifold and w58 transmission.

Make engine mounts. Mine is solid mounted with some brackets made at home works great would do it again.

Trans cross member custom mine is square tube with some angle iron with the toyota trans mount bolted thru it. Then it is bolted thru the miata frame rails. I need to cut out a section of frame rail and weld in some 2x2 tube or similar I do not currently have this but will.

Rear. I am using a TurboII RX7 rear with custom rear cross member to hold the snout in place. there are about 10 different ways to do it just pick one you are comfortable with.

Fuel system. I have a walbro 255 intank and bosch 044 inlive -6an aluminum feed with stock feed as return.

Brakes Miata sport breaks all the way around work great.

Wiring and power goals are the killers of the whole project. Make sure you know what you want when you start makes things a whole lot easier to begin with.

I have a custom wiring harness I did myself prob took me about 100 hours to get it right. I have redone numerous things because my initial goal was 400 whp. After driving the car this is not enough so the new goal is 600-650. I would have done a few things different had I known this from day one.

Mounting the engine and transmission is one of the easiest parts. Wiring will by far take the most time out of all of it. Pick a fuel management system that will fit your needs. I was going to use megasquirt but since the support for the 2j is not there yet. I ended up buying a used AEM V1 witch is what I will be tuning with very soon. If you are confident enough to get the engine and trans in the car and wire it you will have no problems. I was a little scared of wiring when I started my project now wiring does not worry me at all. You can go the easy route and call Dr. Tweak and have him make you up a harness or you can do it yourself both work.

Once the engine is in the car and running you will run into a million small issue that may or maynot drive you crazy. For example. Temp gauge on the dash I had to mount a miata coolant temp sensor in the water neck and run a wire directly to the dash. The tach would not work with the 2j ignitor so I mounted an autometer tach into the stock location and wired that in. Oil preasure I use an after market gauge. The speedo will work with the toyota transmissioin W58,W55, or R154, using a MKIII R154 speedo drive unit. In my case the speedo works out to be within 4 mph. Other small things may drive you insane like a broken wire or bad ground. Make sure you ground the hell out of the 1j they dont like not having a billion grounds. If you can deal with all that then its 100% worth it. Let me know if I can give anymore incite.

Ok for everyone still watching this build I have a few updates. I finally broke down and bought an AEM V1 so I will be installing that soon. Also my new trans is already making noise so I have started collection parts to switch to a th400 transmission. I am not usually a fan of using an automatic but in my case I have a friend that has one I can use and local to me we do a lot of roll racing and all my friends drag race so my car is going more in that direction. I need to figure out what stall converter I am going to use and I need to make an adapter to go from the chevy torque converter to the Toyota flex plate. I will keep you all up to date as I go.

4k stall converter? :P

Yea I would
Imagine it's gonna be something like that I have to call around and see what some
People recommend no one seems to sell a converter for a 2jz miata with a th400 and around 500hp lol

Ok so small update on the car. My baby is almost 5 months old now so things are getting a little less hectic and gave me a few free hours the other night. I installed my AEM V1 almost 2 months ago and I was having major problems with it. Come to find out almost all my problems were user error go figure. I did a lot more reading and watched about 3 hours of tuning videos and am having great success.

I was able to get a base tune setup my antilag switch works, and my methanol works and I have a nice map I can use to trigger it depending on engine load. Also small nive feature is that since my antilag is signaled off a manual switch I can do rolling antilag lol.

I will be getting the tune dialed in over the next few weeks and need to renew my tags but I will get some good videos for you guys when its running better. I am still collecting parts for my th400 swap but that will be a winter project. I am just super pumped that one I dont have to pay someone to tune my car.( I was contimplating this because I was having a horrible time with it) and two I love driving it

So is this thing alive yet?

Should have swapped in a 302 after all this work.
