First modications
Hello,
I just would like to know what modication would you get for a stock rx7?
I also would like to know your opinion on the c west bodykit? Here is a picture.
I do want to get rims. Here is Australia everyone has rims from 18" to 20". Do you think 20" inch is far to much?

As i am new and not sure about rotarys, what modications would you need in to to get say...running 15 psi?
Thank you.

As far as rims, I think 18" is the biggest Id go. 19" looks way too big, and 20" is a joke. With 18" people dont usually have rubbing issues too. That might be with some suspension work though...

That is when the secondary comes on, and both turbos are running at once.
Non-Seq. is just when both turbos get the same amount of exhaust flow the whole time. Its more similar to running a single turbo. There is no transition or anything.
Sequential will reach high boost quicker and will put out the same hp numbers as non seq. Non-seq is what most people do for simplicity, usually because they cant diagnose the stock sequential set up due to its complexity.

umm i am a TII guy but arent the fd turbos the same size?
and from most of the dynos i have seen non sequential seems to produce more peak power but the lengths of power bands (or area underneath the curve of a dyno plot) are essentially the same

With non-sequential, you are giving up a 1000 rpm of powerband and quicker spooling to achieve a smoother powerband and increased boost reliability. Anybody not admitting those facts is either ignorant, deluded, or is a liar.

Yes, the FD twins are both Hitachi HT-12s. Non-sequential supposedly creates a little more power than sequential because some restrictions are removed from the exhaust path. However, no one has actually documented any increase. Non-sequential has a narrower powerband, period. It won't make more power than sequential (not including any benefits gained by going TRUE non-sequential and removing exhaust restrictions).

Hello everyone, sorry to bother you all. I just want to know when racing someone at a stop, what RPM do you take off at?
At what RPM does the wheels start to spin and lose traction?
Thank you.
