supercharging - injector size


350zlew

Recommended Posts

Hiya im new to this forum and just need a bit of advice on injector size forna current project on my z.

Am currently in the process of supercharging it and am aiming for around 380-400bhp.. dont really want to go above that so i need to know what size injectors i need?

 

Ive been told 660cc but these seem pretty big... just need confirmation :-)

Many thanks

Lewis.

I beleive so buddy... aparently all the internals have been replaced and are as new but obviously as they are previously used they are slightly cheaper hence the price :-) fingers crossed they are all good but ill keep u posted :-D

I'm running DW 600cc. Fine for my power levels. (442fwhp)

Previously I was on stock injectors running 380fwhp without issue but they would have been flat-out at WOT.

 

Just a word of caution - If it were me, I would get all your 'new' ebay injectors flow tested before fitment. I can't see the tolerances being that great for that money.

Saving a couple hundred quid on the injectors sounds good but if you get one fail or one cylinder running lean, you'll be spending thoudands before you even know it .

 

And...Welcome to the club. :)

Ive gone for a eaton m90 which we are customising the inlet manifold to fit.. as its a roots style charger like the stillen.. spoken to a few specialists in the uk and they have said theres no reason why it wouldnt work like a stillen charger its just obviously cheaper to acquire :-)

Have a list of parts to get most of which i already have.... just got to find out how much of a bulge is going to have to go in the bonnet after fitting... hmmmm!

 

I know cheaper isnt always better but the charger is being fully rebuilt and teflon coated so it wont be a shabby job as its been a long time in progress and we have had lots of info from different specialists :-)

 

Will post pics when i have some.. :-D

Haha it is buddy... its more of a project tbh :-)

Whats happening is we are getting the top half of the inlet manifold remade out of billett aliminum to fit the charger on top... so once done it should all just bolt on top :-)

Performance wise alot of guys recon it can easily make 400bhp with the right pulley and uprated fuel system... gonna take some figuring out but ill keep posting progress pictures and any problems we come across! Bit of a learning curve hahaha! :-D

Welcome buddy

 

Good that you have researched, Hope those injectors are ok.

 

I have a fair few SC parts in stock plus lots of others available, feel free to contact me.

 

Bear in mind some things are cheap for a reason, sometimes it's cheaper in the long run to by well established brands, your going to need reliable parts on a supercharger build.
