50# injectors and a tb spacer for the ls4 tb. Pm me with what you have and a price. i have paypal ready

 

50#? i havent seen or heard of these yet. 42 and 60 are common for lsj

 

Tb spacer for a drive by wire car....? And 50#ers are a pretty common size just not so much on this application. I bet it would be better a idle than the 60's all though it can be tuned to make it better if you have problems with 60's! (seen complaints of idle surge on 60#ers before)

 

Ive got 50 on mine. And Ive got idle surge issues.

 

I have 60#ers and my idle is smooth...with ac on or off...a lot of it seems to be on how well they r flow matched and ur tune..

 

the 50# injectors are more than enough on an m62. ZZP offers the 50's now instead of the 60's like before

 

But yes if I did it again 50#ers r the way to go on a m62 build...y u selling them if u don't mind me asking

 

me? im looking for them to buy

 

To the O.p. A TB spacer is pretty much useless on a drive by wire car.. Think about it there is no traditional throttle cable to stretch! As far as 50's try an injector vendor! Siemens...

 

Well you DO need a tb spacer when your running an ls4 tb on an m62 sc. so please the next time you try and bash a thread atleast get your facts right. if you dont know **** you dont have sound like you do

 

Never seen the need for a tb spacer on an LS4 tb basically EVER on any SS/SC or even a 2.2/2.4 M62 setup, And the local guy's here have run that setup and never once said anything about a tb spacer.. Im not trying to bash your thread just informing you that it will do you no good and isnt needed. What your thinking of is the ADAPTOR Plate.. Which isnt a spacer...

 

a spacer and adapter is the same thing. your not taking one plate off to replace it with another. the ls4 tb plate is 75mm a stock m62 opening is 70.5mm. therefore you need to add the spacer/adaptor plate to let the ls4 tb fully open. Hence your spacing your ls4 tb out farther than a stock tb

 

^^^^^^^ Boosted FTW

 

Then why is it called an adaptor plate and not a spacer by the people who sell them...?

 

but it spaces the ls4 throttle body farther out from the sc inlet.... spacer so the ls4 can fully open

 

with #50 what size of pulley you can run???

 

50#ers cant be maxxed out on an m62 sc

 

so i can run 2.8 without problem?

 

you can but make sure you have all the other important supporting mods

 

From ZZP
Modification to the blower inlet is required or the larger throttle plate will contact the blower and not allow full opening, for the adapter plate please select Option 1.

 

i run 80s and never had a problem with idle surging, but yes it does take tuning to dial it all in. zzp sells that adapter plate fairly cheap or you can go for an ls4 spacer plate from any car that runs it stock, it doesnt have to sculpted to work it just has to space the tb out from the blower face. be aware that while you can tune big injectors in that tb will always have drivability baggage.

 

so **** stick what is the adapter plate? Its a spacer!!!!!!!!!!!!!!
