b35 tcd s1 injector size? also motor mount requirement

[al525i]

Sent my injectors out to be tested and ultrasonically cleaned... have three of them dead (sat up for several years, so I'm guessing the pintles are stuck)

What should I replace them with?

the build I'm going with so far is:

rebuilt b35 (stock pistons, rods, crank, cam, and valves)
the block is from a late e24 so it has the correct mounting bosses

TCD non-intercooled kit


the working plan is to get it all up and running on the b35 stock motronic 1.3 then Megasquirt a few months later.

What size injectors should I go with for replacements? I'm thinking a whole new set is in order considering three are dead. (completely, non-recoverable) and I don't want to take any chances on fuel supply issues.


also,

I can't seem to find it written anywhere now, but it seems like I need a 533 passenger side motor bracket so it all clears the turbo, is that right?

I believe you run 36lb injectors with the S1 kit on Moronic. With MS, he recommends 60lb units.

A 533/633 passenger side mount is what you need to clear the turbo.

I have a set of red top injectors. I can't remember what they are right now.

[al525i]

i think the red tops are 30lb

if I'm going to have to replace them with 60lb units when I go megasquirt, it may be a better idea to just go ahead and do the megasquirt now

Chris,

How much do you want for the red top injectors?


I'm going to get it up and running on the moronic 1.3 first. I don't need to add even more problems to the mix right now

30lbers for Motronic
42lbers for most MS applications
60lbers for big boost

533i motor mount arm required

Thanks Kyle, Chris, and Todd. Proper parts are on order now so hopefully all is good

We all know that feeling...

Get the plastic body ones I have 80lb injectors vs the old metal green top 42s they idle better, lower dead time.

[Whatisthat]

If it helps at all. My b34 is running a larger t04e turbo on MS with 42lb mustang injectors.

Idles great, runs about 85% idc @ 19psi of boost. 43psi fuel pressure.
