alright!! good news i put a bolt in the return and blokt it she fired up straight away so we know i have low fuel pressure even the its getting gas.i have replaced standard rb20de pump(car was originally rb20de auto) i replaced it with a twin turbo subaru fuel pump.why is this not giving enough pressure if the pump is biggrer and pumps more than the standard one?

i have a sard fuel reg.gas feeds threw bottem out the side and is in the hose that comes off fuel filter.
It's supposed to be on the return line off the end of the fuel rail. I should probably feed into the side and out the bottom. It's designed to maintain a given pressure in the fuel rail (it's not the actual pump that causes the fuel pressure).

What pressure is it set to maintain?

      Yeah, you are right. It seems easier and more reasonable to boost the engine. And as you said the blocks are very similar but the cylinder bores are different.

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Sound logic, but in actuality way more illegal than just having the wrong pipe. Normally, doing something like that would be forgery. Meaning you may have certain documentation for vehicle parts, but the actual parts are different ones and you just assign them the numbers and badging from the documents. But nevermind that. Nonetheless, I AM curious if this pipe was ever made by any official manufacturer this way, because I honestly am not familiar with this pipe layout and shape. As I will be putting on the HKS Silent Hi Power once my exhaust gaskets arrive, as long as it sounds right I will just roll with this front pipe. I can always order the actual Mines part if I run into legal issues. It would be an unnecessary expense as there is lots of other problems I have on this car as of now.

      So, weld a plate with the Mines logo laser cut into it, onto it. Instant Mines pipes, whether they were or weren't originally.

      I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy. Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.
