All the races cars do it, you didn't know? Someone on the internet told me so.

 

 

You're gonna have a bad day. Downpipe needs to be shielded from speedo/throttle cables, wires, brake lines, proportioning valve, and heater hoses when you are finished.

 

Here it is

 

Oil line is twisted and crimped at the turbo.

 

I know I'll take care of that.

 

Very soon

 

What ever happened? All is well with the car I take it?

 

Got the car started after a long year ! very happy now some wiring of all the new stuff I got on the engine and all is ready for dyno powaa

NA to NB coils harness
NA to EV14, dash clt, ecu clt and vvt harness
first time tuning the new engine
some juice

 

I'm a little late to the game here, this made me spit my coffee out. lolololol

I do like how clean that intercooler piping is.Seems like I've seen that on another friends car? What kind of hoses are those? FM uses noodles, they claim they are good for 30psi I think they are 4 ply.

 

First start !

 

Have you test refitted the bonnet to confirm it will still close properly?

May be worth doing that before you put the hose clips on....

 

I couldn't get metal pipes to fit without interference on a shaved hood. I'm interested to see if this fits. is this 2" ?

 

The pipes are 2", 90deg bend with a 2" radius... not easy and not cheap... test fitted, it all fits very well, this is one of three mx5 that get the same over the rad setup.

 

That's awesome. I wish it'd work with 2.25 and 2.5". Alas silicone for me.

 

Will 2" support 400 HP?

 

I don't think so

 

On a stock head 1.8 it ought to. Higher the boost you need to hit that power the less the smaller diameter will hurt you.

 

 

Back of the envelope calculations say 2 inches should flow 400 hp easily. The WRC restrictor is 34mm, at ambient pressure, and it limits cars to 300 hp. 2 inches is 51mm, which is more than double the area of the WRC restrictor, plus the air flowing through those pipes is pressurized so you're getting more mass of air for a given volume.
