If one were to run a set of two turbos would one be able to sum the two boost ratings, or is there some other formula to use?

IE, if i had two turbos that could produce 7 psi, would running them both result in 14 psi?

In short, no. If both made 7psi, it would still be 7psi overall. Think if you had to two 30psi tires, and connected them, they would still be at 30psi.

Ok. So it's like voltage. So what would be the best way of producing 30+psi from a 1.8L engine?

And what stand alone systems are capable of handling such levels?

I think its more like can your motor handle 30 psi. You will need to buy alot of components for the motor to handle anything around 30 psi. You can use the AEM stand alone, Zdyne Stand alone, or Hondata.

I think this guy is running a Toyota, Not a Honda. Either way to run 30psi you are going to need a bulletproof block with some type of standalone managment, Speedpro/Motec/TecII/Accel.

Well, I'm told the rods that come stock with the bottom end I'm planning using can withstand 275+hp, but I'd still rather get custom rods. The pistons that I've decided on are forged and cermaic topped... The block will most likely be bored and re-sleeved, even though it's cast iron. I can't really do anything about the crank though, probably just get the thing shot peened....

As for electronics, I wanted to go with an SDS, but those handle only up to 2 bar. (3 above vacuum). Most systems don't handle past that either...

DONT get ceramic coated pistons, this is SUCH a stupid thing it hurts if this and other "miracle cures" worked why dont manufacturers use it?

answer.. because pistons are a massive heat sink that draw heat away from the combustion chamber into the block and the oil that gets splashed against the back of the piston crowns by oil spray jets..

now your gonna coat them with a substance that deflects heat back into the combustion chamber .. so the heat has to dissipate through the head and cylnder liners..

thus the valves expand too much and stick in their guides, and as ceramics by nature hold heat quite well your making detonation more likely..


also, metal expands, ceramics dont.. so after this stuff is applied, and your engine is running the pistons will expand and the ---- will crack anyway..


what a load of bullshit

build an engine properly.. real power doesnt come bottled,in coatings or any other ---- like that



(and before you ask i have a material science qualification so im quite well qualified to comment on this subject!)

Actually, I'm using OEM Toyota pistons. They come that way.

i stand corrected.. its still a ****** *** thing to do


any pics of these pistons, and do you know EXACTLY what the coating is as "ceramic" is as vauge as me saying "a black one" when asked what car i own
