Roachdiddi. I do not agree with yopur post about taking out a no torque 13b and doing a 2j. yes 2j's make alot of power,HP that is,to make 900rwhp you will need a big turbo so you will loose bottom end power. i have done both, own both a 909 rwhp mkiv, a 736 rwhp fd with a 13RE and i can tell you the fd is a all around more rounded true sports car. you are going to be surprised the lag on a big turbo built mkiv. remember is not how much torque you make, is at what rpm you make it.

very true. but i think you will be surprised at how soon a fully built 2jz gets boost from a gt42
and yes the car is moving under its own power now. drive shaft is in and will be on the dyno soon.
reason 4 not buying a camera... i have no need. havent used one in 27 years

listen the 2jzgte motor will handle 900whp and 700whp all day long no problem. the gt42 is a very nice turbo and will handle 900hp no problem at all. so to anyone that beggs to differ that roachdiddy's project is 100% done the right way. read the specs on it and do your research. if your going to build a 2jzgte rx7 will the good stuff ask roachdiddy!

Tell me if its true, and if it is what have you done to overcome it?

If you havent then your streeing wheel on straight road will always have a mind of its own even when you are holding it tightly with your both hands. Scary part is, your car with can go left and right on its own on even slightest bumps on the road.

Your car would literally swim on the road on its own with these settings. Why?

Because on ground with these settings, the steering box arms will automatically push the outer end to the wheels while car is going on a bump since suspesion compresses and decompress in this process. This push will make the wheels move to odd angle and will certainly make the alignment adjusment out.

This thing even happens when you jack up your car everytime on a lift, and the the wheels alignment automatically becomes out while up.

ur drawing is far off of what the angles should look like. yes the rack was lowered. many companies sell a bump steer kit for the cars. with the bump steer kit it will remove the left and right movement you speak of.

Im not hating or something dear friend. The drawing i drew is something you surely get when car is on the ground.

As you can notice in the original pic of your car on the lift, the angle of the arms highlighted in red is still out of alignment. I can imagine the worst angle when wheels go back to its position on ground with the fenders. And there is no way to fix it, i know, untill and unless you raise the engine to prevent it.


Just for your info, i have done the same swap 8 months before you started or even concieved it. And my FD was running with stock sequential 2JZ turbos at first. Now its running on a single T04S.

i have tein suspension. when lifted on the hoist the wheels drop less than 1/2 in so the angle you see is damn near as bad as it gets.
ill post up some pics after we install the bump steer kit.

You know, it's OK to admit that you don't understand bump steer and that the only thing you do know is that they're going to install a kit on your car to try to eliminate it.

I suspect that the steering rack has been moved so far (as I've pointed out several times) that it will be difficult if not impossible to eliminate all of it.
