460 flows around 460cc per min (numbers is a coincidence) and 123 flows around 300cc/min (google it to be sure) and also has a slower response...

Will i be able to use these Dave or am i best trying to get 4 x 460's?

actually they are MJY100023's does this make a diff?

Will these work as well as 460's?

I knew what you meant Dev.

These don't flow as much as the 460's, and have a slower response. Put them back on the 'bay' - but give information on the flow characteristics first. If you PM Jimster he'll tell you what they are flowwise, as he's running the same ones in his 8-port motor......

can i use 460's on 8 port?

yes - but you don't have an 8-port, or 460's... (confused)

I have two 460's just need two more!

just was thinking about what you said about 's being some of the best injectors.

i'll think on.

What are you trying to do with them???

Im using 2 460's with an Eaton blower very successfully right now

use 4 460's on an eaton blower. with either 7/8 port head.

Your a brave man, sequential injection.......................how long you got LOL

The 460's have blue rings. I know that for a fact.

2.0 litre Rovers used the same injectors as the MPi, need to be late 90s vintage though

Jimster/Dave,

Thanks.

As I'm only looking for around 120 hp from my 998, I think four of the 123s will be big enough, particularly if I raise the fuel pressure a bit.

I haven't tested the 123's - but I'd assume that they are an older generation injector that won't be as fast response as we need for injecting a 5-port A-series...

Axel, 120HP from a 998.................really?? I was going to supercharge and inject (using 2 460's) a 998 but was reckoning on a 100 at most.

What mods are you making to the bottom end?? Just a centre main cap or anything else special?!?!?!?

Others on this site have achieved 140 hp from a turbo 998.

I'm planning on a relatively standard bottom end with the addition of a centre main strap at most.

The thing is, you do not need to run high revs to achieve this sort of power with a turbo. Being an old man, I'll probably never go over 6000rpm. The stresses are more rev related than power related.

140 from a 998, thats just awesome!!!!

Thats it, Im gonna try and get over 100HP now with a supercharger on a 998. Absolutely mental! Im guessing that they just rev nice n freely though rather than drive like pigs

Well it just so happens that I have a brand spanking new MG cam in the shed, cast off from one of my friends but I havent found a use as yet............could have just changed though!

Axel do you have your 4 123's yet?

if not i have 4 with a fuel rail and sockets.

they are going on the 'bay next week so let me know.

yours for 9.99 of your english pounds.

i'll take these if they're right for the old K1100 head which it sounds like they are

obviously axel has first refusal
