just need a quick answer do i need to pound the cross member and under the driver strut tower to fit a ls in the sedan? i know its true for the b16 into crx n watnot didnt know if there was a difference and ive searched it kinda but nothin came up that was straight forward enough

 

yes, the "modification" to the drivers side bulkhead will be neccesary.

crossmember depends entirely on what header you'll be running.

 

what header will allow to fit im not dumpin the car but its definately lowered, i will have 15" slipstreams with 45-50 series tires and its on ebay coilovers that are down to the ground any ideas on a good header for clearence? and i plan on makin a cover plate for it to keep it from gettin trashed on scrapage

 

Anything 4-2-1 and 2-piece will be a much tighter fit to the oil pan and give more ground clearance.

one-piece 4-1 headers generally hang lower.

 

k good im plannin on a 4-2-1 header anyway thanks for the info

 

no problem dude.

 

Not if you do what I did and use a D-Series Alt, no pounding needed. I used a 4-1 and modded my crossmember for the header to fit.

 

I know this is a nub question but wtf is a d-series alt like alternator? and just to double check i need teg axles i have the int. shaft and linkage i need to cut to fit, i need throttle cable and clutch cable?
Any other input on wat i will need to pick up im getting just the motor/tranny from a friend i have the engine harness too

 

you don't need to change the clutch cable, and I reused my stock SI throttle cable with a custom fabbed $.50 bracket from the hardware store.

 

ok thanks for the feedback i'll see how that works and keep you all posted i have to wait for a friend to deliver the motor then the work beings

 

i got a 97ls in my ef hatch, it has a 4-1.. but for the 4-1 to fit, the crossmember was notched out a prettty good amount.. and the ls is bigger than a b16 so its even closer to the bulkhead, def needs to be "beaten"..

 

great to hear thanks so i'll go out and buy a new big sledge hammer lol

 

O reary? Pretty sure they are the same size there guy.

 

ha, yea they definately have the same dimensions.

 

A b18 is bigger than a b16! 18 is more than 16 therefore it's bigger. Sheesh people.

 

yeah dude a ls is noticibly bigger than a b16 even if ur blind..

 

b18 is a taller block, so in a way he's right.....

 

^see above post^

 

The extra .2l of displacement is from the longer 89mm stroke. The block doesnt have to be taller to increase the stroke.. You'll also notice the ls has a different rod to stroke ratio. It's like that for a reason

 

The block IS taller tho. It's the reason b16a headers will usually touch a b18's oilpan.

ever notice that b18 headers are different part numbers from the b16a versions?

It's like that for a reason
