ok my question is i have a 07 balt and the hahn intake manifold and i want to run the Ls4 tb, what yr tb would i need and what tb adapter plate?

 

are there any sites that sell the LS4 i havent even seen it lately? i need one too for my OTT intake that im lookin to get

 

im not really sure. ive seen a few people sell them.
im really just looking for a upgraded tb for my build.

 

Whats the hahn intake made for? The LSJ TB or the L61? If it was made for the LSJ TB then get the adapter plate from RAW or who ever sells it now. The L61 or LSJ TB should be sufficient enough.

 

zzp sells used ones for$ 99.00.

 

^ i didnt know that

 

ok i think the intake manifold is matched with the L61.
do you happen to know the exact size of the LSJ tb or the 2.4? Ive heard 68 to 70mm
the reason for the LS4 is because i will be in the area of 600hp

 

stock lsj is 67.4 mm

 

what size is the ls4?

 

i was lead to believe it was 78mm for the LS4

 

LS4 is 75 mm

 

so then theres no difference in the LS4 tb and the LS1 because gm uses the LS1 tb (75mm) on the drag cars

 

same size yepp..according to zzp.. thats where i found the sizes

 

ok so just for future reference the LE5 2.4L has a 64.6mm
the LSJ has a 67.4mm
and the LS1 and LS4 have a 75mm

all brand new parts for GM cars. where i got a 2.4 IM/TB setup for like 300shipped

 

honestly i would use a 2.4tb i am.

 

i think its too small too spool my turbo at 32lbs of boost

 

id go 75mm in that case..

 

no its not too small at all hondas do it all the damn time. i see problems in your future you need to look into another way of spark. the stock coil on plug will not work at that hp level FYI..

 

im going stand alone engine management (Fast XFI) and im just gathering parts the real work is being done by 2 different places. Jotech Motorsports and Marty Ladwig Racing/GM racing.
but you do have a good point on the honda running them it slipped my mind. most of the honda guys i know all have 75mm tb from skunk2

 

yeah you dont need a huge TB. just good flow. if you go aftermaket spark you will need to install a crank position sencer and mount a trigger wheel for the dizzy

 

well i know that the 07 2.2's placed a crank sensor on the crank so that should be taken care of. im just having that one taken off and placed on my eagle crank. as far as the trigger wheel i spoke to FAST already and they said that they have one for my application

 

hope your trani holds. i got basicly the same setup but for a procharger setup. on soon to be 21lbs of boost. i just dont got a sleaved block or eagle crank

 

hey ion what made u go with the comp blower cams? i was look at some comp cams today and im not sure which ones to go with..are these cams specific to motors with a blower? the 2.0 ecotec and how much did they run u.. the kit i was lookin at was like $459

 

yup that sounds good man. what do u run in the 1/4?
the tranny issue im thinking of cryo treating it and using a stage 4 or 5 custom exedy clutch and the light exedy flywheel

o and dss axles. i just dont know what stage to get at the moment. the 2 or the 3
