Default Will this fuel pump work?

Should this Walbro 190 fuel pump work for my 1993 Intercooled, GReddy turbo'd, Miata. I know it says for 1994-1997, but shouldn't it be a direct replacement for my 1993 also?

Or do you have a better place to get a fuel pump or a better pump for the money that you can point me to. Thanks in advice for any help.

That's the "normal" pressure 190lph pump; what you want is the 190lph HP pump, as it maintains fow at the higher pressures it's going to see on an AFPR setup. You can get them here for $84 plus shipping all day long: http://shopping.lightningmotorsports..._Kit-p-89.html

The part # for the high pressure version is F20000141.

Thanks... I assume you've bought from those people and they are a good source?

What's the general consensus on the 255lph/HP pump? I think that's what I've been using for years but I could be wrong.

I believe, and I'm sure to be corrected if wrong, that the 255lph can overpower the fueling in non-boost applications and can even cause stumble at idle. If you were to look at graphs of both pumps you'd see that the 190lphHP pump actually provides more fuel during high boost pressures than does the 255lph pump.

Well... that's good, because I just placed the order today. I also went ahead and ordered some 1.8 injectors from www.partsgroup.com. So hopefully I should be set to go to the next level of boost.

I've got some buddies lined up to help with a clutch installation at the next Miata tech day in November at the Mazda dealership.

170+rwhp here we come $1550 total investment so far.

Do I remember reading awhile back that the Walbro's have some reliability issues. Also(probably covered at length) does the 1.8 stock pump flow more than the 1.6 stock pump.

Bottom line is that the 190HP pump and a dual feed rail is a super cheap $100 setup that will support up to about 15psi. Even if you're not going to run that much, it makes sense for the price to do it from a "cover your ***" standpoint.

Great... Now you post it after I have already ordered one. I wish I would have read this post before.
