i have an 94 ls integra. and i bought a 95 gsr long block with no intake manifold and i was wondering if the type r manifold will bolt up to the gsr head. i thought it did until i saw 2 people post that it could but it has to be modified. is this true??


also, can i use my ls header and cat or do/can i use gsr header with ls cat??

thanks

 

the manifold should work just fine

 

the type R manifold will NOT fit on a GSR head.

(type R) single runner dual runner (GSR)

 

oh, if you want an ITR manifold on your GSR head, you'll have to buy a skunk2 one - it's the same design but it fits.

 

yea, i found that out. imma go with the skunk2. what is the difference between single and dual plain and how does it work?


but does anyone know about my other question
"also, can i use my ls header and cat or do/can i use gsr header with ls cat?? "

 

LS header will not fit.. I have a GSR header if you want one.. let me know

 

gsr has another set of butterflies that open at 5800rpm

 

hmm the ITR intake manifold can be modified to fit the LS ... i thought
for sure it fit the GSR ... on me ):

 

no the type r manifold will not fit, you have to get the skunk 2 manifold.

 

skunk

 

Single short runners like the type R will give more top end power.

Longer runners like the LS manifold gives more low end power because of proper swirling mixing of the air/fuel mixture at lower rpms.

The GSR dual runners will give the best of both worlds and have a very nice midrange. That's why the GSRs have such a flat torque curve. However, because it is essentially still a dual "long" runner even when the butterflies open for the air to shortcut into the short runner directly to the head, the GSR manifold runners have too much surface area = extra friction = less air flowing to head at high rpms = not so great top end like the type R but more midrange and low end.

Hope that helped

yes it will. My car is an 4 door LS with a GSR motor. for a while i was using my LS header and cat.didnt have to modify the b-pipe at all. now i have a 5zigen header for a Type R and test pipe. still didnt have to modify my b pipe at all. any questions just ask away.

Actually the ITR will not be a direct fit but you can modify it so that it will fit the gsr head. For the money u might as well get the skunk2 mani.

 

itr intake manifold dont fit on the gsr head?? humm... i thot i does.. how come one of my frien had a b16 head with itr manifold? fits rite in.. and he uses b18 block...

 

b16 and ITR head are the same...except the ITR one flows better
