I've searched but haven't found anything definitive but I just wanted to check with you guys.

If I want to go above 6psi on my Begi Series 1 I will need a new fuel pump, injectors, and something like MS (Currently using the rising rate fuel pressure regulator from Begi). That sound about right?

I think just a megasquirt and injectors would take care of it. My stock fuel pump hasn't had any problems yet.

My pump doesn't seem to have any trouble with 13psi and MS.

MS and injectors, pump SHOULD be ok.

I thought the stock pump couldn't go above 70-80psi and you would need 100psi or so at 7-8 psi of boost.

...or is that just dealt with by having a longer pulse?

if you switch to a MS, you would eliminate that FPR and go back to the stock one. to hit 70psi of fuel pressure you'd need to be running almost 27psi of boost.

Bigger injectors allow you to get more gas to the motor at the same fuel pressure.

my fuel pump **** the bed at 197whp...actually a ways before that. I put in a walbro 255 and it will make it over 300whp on the stock ****.

I have a spare, new 190plh if you want to buy that ******.

Jeff25rs

How much?

pdexta: thanks that makes sense.

So the MSPNP seems like a massive amount of work and money that I can't commit right now do you guys think it would be reasonable to just do a piggy back like the voodoo box if I don't want to go above 180hp or so for now?

no because that will mean using your fuel pressure regulator and do you really think you want to run 100+ psi in your fuel lines... your stock 100k or more miles fuel lines?

I mean ****, I ran my 12:1 FPR for 5 or so months with 6 psi and felt pretty uneasy about how much pressure the fuel was at... no worries about it now as I just put the 460's in and removed the FPR.

I'd be much more concerned about what the stock ecu does with all that fuel once you hit open loop mode.

Jeff; what would be the price of the Voodoo box? Be on the lookout for used MSs. It will be more than worth your effort.

bandaids are the antithesis to someone trying to get a well running quick miata.

mspnp is pretty ******* easy, especially with all the support here. If you can't figure it out, then you're a Down's baby and we don't need you here...thintheherd.txt

Jeff25rs

voodoo is $400 or so
a MSPNP is $700. I know you can find the non-PNP MS for $400 but I'm not sure how much extra work those would be.

Also do you guys have any recommendations on injectors. I was looking at the 460cc rx-7 injectors. Also any recommendations on where to purchase said injectors from?

30 minutes of installation, 20 minutes of which is running a single vacuum line, and a couple hours on a dyno is 'a massive amount of work'?

Jeff25rs

That doesn't seem bad. I just glanced at this manual and it looked like a giant ******* wall of text:

Braineack how much would it cost me to get one of your MS setups? I'm not entirely sure what options I would need. (I think I would go with the stand alone with a/c?)

Rafa

Yes but, that's a new MS. I sold my MS for 96/97 for something like $550 if I remember well. I mentioned a used MS because I see some forum members buying the new Adaptronic ECUs so I figure, maybe some deal will come up.

In all of the posts I see no mention of an intercooler. It is needed above 6 psi. Oh, and a clutch.
