My friend (landon 303) doesn't have one either and he's been on longer than me. I think it may be the vendor status that keeps it from showing up

that's probably it, seems pretty consistent with everyone else.

edit: oh and post #12,000!

of course you can, usually ships them out the same day too

just startn 10-16-11 05:19 PM

Hm intersting rob. I didnt know marren sold the newer style injectors but i also never looked What CC's are them 2000?

gear_grinder 10-16-11 08:32 PM

price and sizing options?

nvm just found the website lol

gear_grinder 10-17-11 09:41 AM

any idea/pictures on the fitment of the delco/rochester/multec2 injectors?? those are looking the best to me ATM because they come factory in the larger sizes (unmodified injectors) and are cheaper then modded or unmodded densos

they are a pain in the arse unless you get the "import" modified ones from marren
these have 11mm tops and a skirt bottom that are intended to be total replacements for stock injectors
they have a spray difuser built in so i take the opportunity to bin the plastic mazda cups and instead use mazda base rubbers to restore the lost height and make the tops snug in the rails

if you wish to fit normal rochys then you will find the 14mm tops require mods to the injector or the rail and the injector body can foul on the centre plate
( unless you bring them up slightly on the mazda base rubbers like i have mentioned above )
[ the number of bottom rubbers you use will depend on if you keep the mazda 2 piece difuser or just part of it or none at all ]

i have fitted the marren version to a fair few vehicles,, some only as secondaries and some as 4 x 1000

i was just thinking of running some 1000cc for secondarys, the spec sheet on marrens website show them being 14mm tops....

bumpstart 10-17-11 08:08 PM

1000 cc- 051000PI
870 cc- 05850PI
750 cc-05750PI

the "PI" bit means performance import ,, which means modded for 11 mm tops
standard rochys have 14mm top and 16 mm base o rings and are not direct fit like the marrens above

gear_grinder 10-18-11 07:51 AM

that 1000cc part number now shows a picture of a modded denso on marrens website.

bumpstart 10-18-11 10:22 PM

from directly under their picture-

Photos are for representation only, the actual product may vary.
above i show you my own pictures of what you get
- labeled marren, marren ID individually engraved for blueprint matching purpose, with twin 11mm tops and skirt base
that are clearly modified versions of the 0596 ( 14mm tops ) multechs

they fit and in practice they work
yes there is other more modern options -that cost more-
