Since we dont know which 4g64 you have, I would guess it is a 7 bolt. The point is you will not be turning your 4g64 into a 4g63, you still would have a 4g64, your thread name is misleading and confusing. Maybe you can change it. Mandy ,

Well the reason for my request is that there have been all kinds of numbers posted about this combo. Some as high as 14 to 1. Thanks Mandy

Did you measure static or at least cranking comp on this motor. Mandy

Dont, read and you will see why.

Nice set up, have you done a cranking comp. test after adding the new head?

Very true hot tanking was prohibited many years ago due to pollution, I said hot tank as a common language in the trade but it is really an oven nowdays.Mandy

For sure have your block hot tanked, your crank looks like it needs to be cut, there are some good marks on there, take to machine shop and maybe it may just need polishing, let them make the decision. WE sometimes try to save a few bucks and pay the price later, have rods check by machine shop...

I think he is referring to something else.

Care to share this pump trick?

Nice glad for you, I am sure you are going to enjoy this car a lot,mandy

Looks good, I made a hood out of fiber with the 2 humps also without the scoop, I have made a new one but with vents instead of the humps. Mandy

Very nice congratulations. What are those engine mounts? Mandy

Did you forget what mother told you about talking with your mouth full?

Open track days are a lot of fun, this usage would change things, I am talking about strut braces, a member of this forum makes them and it should be one of the first things I would add. Look at the track layout and see how many turns are left or right, this will tell you about mods to fuel and...

Did you change the gauge, Or added a new one?

More is not always better for a road course, more so if it is a small track, you already have the base for a good , powerful engine. Try to get true 16 g or similar but not chinese, use your eprom ecu and go with ecmlink, run speed density and run e85 if available,you can sell the injectors you...

SO you did something else to the engine besides the oring. I dont think putting more miles on engine is going to help that much, you need to do the oil pressure mod on your oil pump. Deleting the balance shafts is probably the reason for the problem.Mandy

Hope that solves your problem, still ?

You may have to go to an underdrive pulley on your wp, I am sure you dont turn your KIA or your ALTIMA, the same RPM, RPMS will also kill wp, alt, ps. Do all the above about cleaning your system, but maybe start looking for an underdrive pulley for your next one.Mandy

Go to any auto part store and find your belt , this is not rocket science get familiar with the nomenclature of the brand you prefer, the part number on the belt will tell you , number of ribs and size of belt, the first number or letter will tell you it is a multi rib, the second set is how...

A long shot, have you check pulley damage.

Congratulations on a very clean car, not many left in that condition. By the way I am sure we are close to each other, I stay at a house close to Marlin stadium, which I am repairing and the other by eureka drive.

Your last post did not translate. Mandy

Jake 8.8 are really not that heavy, they are lighter than an rx8 one, dont know how heavy are ours, the Expedition one is different on the front mounts and a little heavier than the Mustang.

Welcome, have a friend from Curitiva, he is very involve with the road racing groups and the stock car racing guys, since he is the rep for Bilstein, I will have him get in touch with you. Mandy

Your injectors probably are not the problem, it sounds like a tuning issue. Post a log.

The other way around, always from inside the car, not outside.

Easy way to check size of sway bar. Use the open end of wrench.

The crank is not ground down, it is only for polishing, it will not reduce its strenght , this is the last procedure when a crank is cut all the time. Knife edging is not recommended, unless it is a full race engine, not a daily nor a once in awhile pull, like I said a dedicated race engine.

If you are thinking of dropping the oil pan, do it now and start fresh, you will be able to get a better idea of what you have, and then proceed with your oil changes. Just about any brand oil will suffice for your first or second change. You could add a quart of tranny oil, mineral spirits...

Agree 100% you will get better quality and perfect fit.

If crank had been cut, the machine shop should have stamped the new size on the crank. I think there is a misunderstanding between parties. Mandy

Take your pictures now, so we can all see the damage.

Glad it is coming along, hope you have pictures of steering and suspension soon.

Glad you posted today, I was about to ask for updates. Keep up the work.

You will probably need new guides and seals also, besides your valve job.

^^^^

Although not my position to reply, the subframe does not need to be cut out, I have taken measurements of this same engine and the inner space between the subframe and it shows plenty of space. In the Miatas the same cuts are done to the firewall and the very backend corners of the frames, and...

Nice start, I think you have started something that many wanted to do, but for many reasons have never tried. I disagree with most of what was posted in your other thread, your dad is probably and old time Hot Rodder and this does not seem to him as a big deal. The complete firewall wont have to...

same here

Go RWD and end the tranny misery.Mandy

How did we go from bottom of car to the top? If you really want to tighten the car, the first add on I would get are the fender braces made by a member here, "greengoblin", but you have to get them as soon as he starts making them as they go pretty fast. I dont have them on mine as I go from the...

These are the measurements--depth 1 7/8--width 5 5/8--length 42 1/2. For the price I dont think they can be beat. Brandon look at your floorboard they are probably raised the same amount as the bottom. This is a great add on as our cars are weak in this area. Mandy

V8 roadsters makes braces for Miata and by their measurements they should fit, call them and find the exact numbers. Mandy

Same here.

Had nothing but problems, City made me move cars, so now I have them stored away hope to find a place to work on them, I have also had health problems. I have made a new hood and bumper mold and had the parts made, I also made one for a Miata, also a trunk that fits an NA and NB, besides...

It is still a polycarbonate. How are you going to refuel or maybe only fuel up, funnel, can with a spout? If you are using a close to stock tank location, I think the best is the stock filler. Even a 5 galon can at that height gets pretty heavy, but if you like it there, fine with me.

I really dont like the idea of the fuel filler neck, I would not place it on the quarter window. I think you will have spillage all over the plexi and down the side of the car, if later you want to go to a dry-break system, the plastic will not hold up to a dump can.Mandy

You will be border line, winches are rated on a straight pull, which will not be your case, it will depend a lot on trailer height, ramp angle and attachment point on the car. Dont ever unclutch, going up or down. Make sure noone is behind car, it may sound bumb but I have seen accidents...

Very nice clean work, congratulations.
