big tube headers vs toda

**hengis** · 23-02-2010 05:09 AM

hey i think its a silly question but i'm gonna ask anyway... i know toda > all headers
and yes i've seen the comparisons

but on a b18c2/b20 setup, do toda still rules all bseries still? or is RMF the way to go

Also interested in this for B20 setup.. Considering either Blox Big Tube OR Toda

With TODA you'll not only get great peak power,
But you'll get the best power band across the rev range.
This is built 160kw+ 2.L B-series...
So much so that we don't use anything else on 2L B-series where a high specific power target must be met. 150~160kw.
If our engine customer's power target is over this, we also have a TODA designed SPL header available that suits this application.

Well i'll be doing back to back dyno runs soon, so we'll find out soon i hope and see how it goes on a non-built b20

If you have I/H/E on it, it should make like 120kw? Without that I suppose you'd be looking at around 105-110kw?

Let us know, will be interesting

apparently the car was tuned by dynodave with this setup: RMF headers, 2.5 inch cat and 5zigen muffler.

i'll be swapping that out for toda headers, racepipe, mugen twinloop

lets see if there are any gains. if Not - SELL the JDM crap =P

Fair enough... Do a back to back test if possible...

But keep an eye on your mixtures if it's not being tuned to suit.
It may lean out on you in the midrange with the TODA's if it's already tuned for the RMF's

its not headers that make the power its a combination of things
that have to work together

in saying that i have toda headers and was very happy
but now have somw nice spoon headers cant wait to get them on to see the difference

A full on built B20 I don't think you can go past the custom Hytech anti reversion headers. The Hytech custom headers pretty much mimick the TODA dyno power curve but with slightly more hp.
