2jz Miata build thread

So much misinformation in this thread, first of all... a 2JZ-GE and a W58 both which are what the OP mentioned are being used could total up to a maximum of $1500. GE engines usually cost 400-700 in good running condition, W58 which is the weakest tranny (good for 400-480whp depending on driving) costs about $400-600. A 2JZ-GE is good for up to 700whp, however that transmission won't be able to match it. The tranny you should have considered for this swap should have been a R154. Also as I mentioned in another thread, that engine is SUPER heavy but 800lbs seems to be right for engine/tranny.

I can keep an eye out but the guy to ask is Slo_SC3 on supra forums he is the one who found mine and he is one of those guys that just seems to fall into them all the time. I will say this next time i am going to use a 1jz or a 1.5jz so i can have some more hood clearance but for now it will just hang out there.

Someone just posted that earlier in this thread..
This should be a pretty sick little street car. Good stuff fella.
What sort of bracing are you adding to the chassis? Roll Bar should be on your short list, don't want you going and getting yourself squished.
Wheels/tires/Suspension plans?

I have a hard dog bar that we have added a harness cross bar. The trans cross member add a good bit but I am in the process of building a butterfly like brace for under that car it will probably come out more like a big X brace and Ill see how that works out if the car dose not feel stiff enough it will get a full cage. I am also running a 1 7/8" piece of tubing between the front frame rails where the radiator is to try and strengthen that area up to. I also have a rear cross member brace too. If anyone has any other ideas to add please let me know.
Read this for starters FM seam welding diagrams
Can also read through Targa Miata and pick out the useful chassis bits if you've got time.
As well, you can stitch up the front subframe, and I'd add material to if in a few places to strengthen it if you're looking for rigidity there. As well, welding near the firewall is going to be more effective than around the radiator core support, IMO. There is some important structure up there, but its not the bulk of it.
Lastly, there are stock braces available on the later NB cars with the sport package, the Mazdaspeed, and all cars after I think 2003, that can be retrofitted very easily, which might be a good idea to look into. One such brace is similar to the center section of the butterfly brace. but there are other useful pieces to the setup as well.

See here:

Original version (1 or 2 made and still around) ran a boosted 13B - see You Tube.
Later versions run a supercharged Lexus V8, apparently chosen for a combination of size, and smoothness - I've seen footage of an Australian 50c coin balanced on its edge (they have chamfered edges) on a running Lexus V8.
They sound WICKED!!!!!
