well i recently had my car dynoed and i was able to hit 213whp and 151tq in my b20vtec. i already knew my header was holding me back however wasnt planning on purchasing a new header til late summer. friday i ended up bashing my header on the freeway totally smashing the fourth runner.

Now the real question is who out there makes a header with better clearance than the DC. i DO NOT want to modify my oil pan or anyting else. ive seen tons of threads with headers that make power and thats great but i want CLEARANCE.

if you're going to put a good header on your car, raise the car up.... and you can get great clearances with smsp, an-r, bisimoto, rmf, and dtr/sixsigma side sweeper

 

The SMSP actually sits further from the ground than the oil pan Add this manifold and you're past 220whp.

*Edit* Not quite, but close

 

is that oil pan modifed to fit the header? or is that how it really sits? cuz thats sexy as hell

 

Thats exactly how she sits, no modification at all. Dave's done his homework, and yes it sure is sexy as hell

Above is my ITR header made to fit around the stock ITR tranny/block support.

Below in my other B18vtec header where the mount must be removed.

 

profab. 500 bucks.

 

With the Profab you need to "modify" the oil pan.

I know Hella had to beat on his oil pan a little bit, he has a C5 motor.

 

Wont that header increase oil temp?

 

This was copied:

we installed 2 pro-fabs and both of them needed alot of work to go in.

basically for you to make these fit with ease, you'll have to take out your rad and install 2 slim fans. Some people say you can get away with one slim fan which is true. but I would do 2 slims fans cause its less of a headache if you do.
also, you'll have to remove some bolts from the flywheel cover plate and and smash in a part of the oil pan so the header doesn't rub.

They will look the same as on the B18 block

 

whoops! Like I said, rock my header so you can auto-x this sunday!

 

blah, header or not, its still either to dent up a header or a oil pan. your pick. this was me about a year ago and still ran it with tad bit of oil for 50 miles back on the highway.






The SMSP and the Toda header all seems to hug the oil pan real nice.
