Does the JDM/sir (raised center) hood add any clearance?

 

Yup, not too sure but the reason they raised the hood like that is to fit the B16
but it does add more clearance

 

i have a jdm crx and a b16 swapped usdm crx. you can fit a b16 in with a usdm hood just fine. the b16s and ls motors are about half an inch shorter than the rest of the b series engines. i was staring at the underside of the hood today and it looks like it adds about an inch of clearance. plenty safe for a swap!

 

alright kool..but it doesnt add enough for an h-series right?

 

Nope

 

I didn't have any issues with the B16 but I swapped an ITR in and then had clearance issues. I bought the VIS JDM style carbon hood and it does have quite a bit more clearance than the stock unit. Not sure about H series though. This just came up on another post though, I posted some pics of the inside of my hood to give you a better idea. Here's the link.

Will DEFINATELY NOT have room for an H, maybe if you get a JDM style hood and hood spacers but H blocks are really tall man. I have a roommate with an H23 from a JDM Accord SI-R wagon, its not in a Civic but I was still amazed at how big the motor is, no wonder they call it the big block 4.

 

message 88hatchy he makes JDM style stock looking high clearance hoods. excellent quality, and youd never know it was that much clearance from the outside.

 

thanks a lot guys for your help
