Title: 13B heat exchange...
Post by: Andy B on February 19, 2008, 03:52:28 PM
Hi Guys,

Im looking at the possiblilty of replacing the heat exchanger with a something a little less... bulky...

its just so big! and im after a bit more room to work with

would making a tubular manifold up cause any power drain or any other adverse effects?

Thanks for any advice!
Andy

nah, i mean the exhaust manifold/heat exchanger under the heat sheild in that photo...

im looking at changing it for a tubular manifold thats dimensionally smaller so i have more room to work with...

i should be able to make up a manifold without too much trouble with the help from a friend.. im just wondering if its going to cause problems down the line when i finally get it running again....

Cheers,
Andy

sorry, my bad :Hammer

is a n/a 13B fc motor

if im honest, its out of my friends car... he wrote it off a couple of months ago, but never declared it to the insurance, and since the engine was sweet and a shame to waste, he let me have it to put in a project kit car of mine... hence why i need the space at the manifold side of the engine.....

Cheers,
Andy

ahhh in that case if its going into a kit car junk the heat exchanger and get a tubular exhaust manifold made up, you will gain power

Yep, 2 into 1 system will give you the best power - most of the big names in rotary parts will have them off the shelf :yes
