Recently I have purchased an MSD high flow fuel pump (MSD 2225) but have not yet installed it, for my 89 CRX turbo project. I do have a B&M FPR and gauge installed. Does anybody know whether or not I'll need a fuel pump voltage booster (running >8psi boost) for this pump? Also should I mount the pump in line before the stock fuel filter or should I mount it between the filter and the rail. I read somewhere that the vacuum dependant fuel pumps are installed on the fuel return, but this is a 12V pump. My pump did not come with instructions . buggers. Has anybody got this setup/any tips?
More recently I have purchased some DSM injectors (I have a pic but don't know how to post it!). They each have green tips and two small injector holes. On one side they say (5)or(6) "MDL 450" and on the other, (947) "INP-018". If these are the 450cc's then I'll know to set my SAFC to -35 and tune from there. But are they?

Please help me out, I've been collecting parts, researching and building this setup for two years and am right in the middle of the install!

ps- I'm looking for information on a radiator upgrade/install. I have a 92 rad but can't make it fit!!!! I checked FAQ, it's driving me nuts!

 

Who's running a high flow fuel pump? Where's it mounted?
In-line or in tank?

 

Im running a Walbro 255hp in the tank.. You dont need a voltage booster, just run bigger wire straight from the battery with a relay ran off of your stock fuel pump..

 

do u only need a bigger power wire or one for ground too?
