What are the best injectorss

[needham]

hi there,

Just wondered if anyone can help me out. i have a 93 fd and im lookin at increasin the power, now i heard that injectors are a good idea, i recently have had a rebuild polished ported engine, apexi ecu, remap, new exhaust, sports box....only got 280 at the fly (want more lol )

Guys whats the best injectors for an fd ?

Really depens on what mods you have and what you want, if going single turbo, it would be slightly different to staying on twins.
For big power (single turbo) we have a new batch of these coming out of the anodisers next week.

if staying twins and without pushing them to limits you could upgrade your injectors to ones that fit your existing rail.

well i have a rebuilt engine with polished ports, apexi with remap, exh and filters, thats it really..
 
my aim was for 300bp but only managed 280,,,, damm it LOL

any ideas ?

for such a small amount of extra power, you could probably make that on what youve got, or look for some 1300 that will slot in to you existing rail.

thanks, any idea where i can get some...
 
and if i wanted more lol :mmmm

I have a some 850\'s which will be fine for what your after send us an email mate dwarfslapper at aol .com:cheers

the FD runs 850\'s in the secondaries anyways

unless you are meaning to put these in place of the primaries

1200cc slots straight in get em from rx7.com. to be fair i know a few people in japan running stock injectors and just better pump and running 380 rwhp! so i would say change your pump if you haven\'t alredy.

hiya needham mate....

I reckon you could (should) be getting more power with what you\'ve got already... bit odd that\'s it so low with what you\'ve done so far...

i have to second that, you are getting stck hp with a ported motor which doesnt sound right.

[needham]

i know im gettin angry hehe
 
hi red
 
SO THE rex has 850\'s as standard?

[Ricco_04]

2x 850\'s in the secondary rail and 2x 550\'s in the primary rail is standard setup

Popular mod is to get 2 850\'s and have the primary rail machined to get them to sit properly.  You will then be running 850x4

cool,. this may sound like a really dumb thing, but what do the primary ones do exactly

Iv had a rebuild with a street port, running WGT silenced decat nurspec box and uprated fuel pump with apexi pfc mapped by WGT and im seeing 320 at fly. so id go fuel pump 1st then bigger injectors later for even more power.

There is some posts on here which explain in more detail of other than just \' they add fuel to the the mix! -  I remember reading them, they tell you what rpm this and that happens etc. Just had a quick look but cant find - I would tell you what I remember but I would probably be a bit wide of the mark! :rolleyes:
