Wait, I am assuming that you are using a true relocation unit and not a sandwich plate adapter. If this is correct, the here is the correct hook up. Out port on the engine block adapter to the in port on the filter hanger / adapter, then out port of the filter hanger / adapter to the top port...

The way that the RX-7 cooler is soppost to be routed is out of the motor, into the top of the cooler, out of lower side port of the cooler and back to the motor. The RX-7 cooler will flow in either direction with no problems, just if it is hooked up backwards, the temp control valve will no...

Not exactly true. Double wishbone type suspensions typically have more camber gain as the suspension is compressed and this allows the tire to remain flat on the ground as the body rolls and the suspension compresses. If the suspension system matains proper geometry through out its entire range...

Unless the exhaust leak is before the turbo (i.e. somewhere between the head and the turbo), then that will affect the boost. Think of a wastegate, it is nothing more then a device that gives a controlled exhaust leak pre-turbo. Other then that, yes, any leak after the turbo will have either...

Oh, something else to add to the topic besides altitude effecting boost pressure is the barometric pressure, temperature and the realitive density of the air. On extremely hot days with a low pressure front coming through (very typical down here in FL when in hurricane season), i have...

Yeah I know, I have actually been lurking around for a while and just dont bother to posting that much being that most of the time its to late and I dont like to repeat what others have already posted unless they are correct and others want to argue that they are wrong or if info is left out...

Not to mention, altitude will also effect it.

The stock wastegate is actually closer to about 9 or 10psi, but due to system restrictions like exhaust and intake tracks, the intake only sees about 6 to 7psi of manual trans cars and about 5psi for auto's. With an unshimmed wastegate, stock turbo, stock IC, 2.5" IC hard piping, and full 3"...

Not fully sure as to why you are asking that or what exactly you are asking and how it pretains to this thread, but a basic answer is cause that is the minimum acceptable pressure for idle conditions. Anything less, then you have a problem somwhere. One thing to remember here guys and not...

He said that the 5 PSI drop was every where, not just at idle. You can not have nor did Toyota design a High Volume / Low Pressure system. Oil Pumps are positive displacement devices and pressure is a byproduct of the volume displaced and the restriction in flow to that volume. The volume is...

I realize that, but porsche does it on there turbo race engines. Also Formula 1 did it back in the day when they were turbocharged.

Actually its the other way around, the stack style Bell-mouth is better for flow. It does seam as if it would disturb flow but it is bennifical. Why all this is, I truely dont know, but I think that it has something to do with the boundry layer and and what not.... All that I do know is that if...

mine was nice and quiet when I first got it. After about a year, it became noisy as hell. It has been in the car screaming its head off for 3years now with no problems except driving me crazy once in a while. You should be fine.

Nice site, but I wounder about there acuracy cause it states that the FN01R-C's that I owned were 17 and 19 respectively and I know that is incorrect unless 5zigen has increased the weight of them cause I weighed mine the day that I got them on a post ofice scale and they matched what 5zigem...

The 5zigen FN01R-C's that are on my car in my sig are 17x8 in the front and 17X9 rear (i no longer have them. Jake owens them now.) Anyways, they are 16lbs ea. for the fronts and 16.5lbs for the rear. About the only wheels that I know for a fact are lighter, but not by much are the SSR...

First thing that I have to ask is which RX-7 and which igniter? There are 5 different igniters that were used on different generations of the RX-7. As for them causing the coil to put out more spark, No. On any and all inductive discharge systems, the coil only puts out what is...
