big tube headers vs toda

[GSi_PSi]

I had the toda 4-2-1 ones on my b20 and now ive got the RMF headers. Downlow+midrange torque the toda was better, but for midrange and up top RMF. Thats why they are called RMF drag headers... Imo if your going to be using the car for trackwork were you drop down in the revs usually midrange etc get the Todas, but just chasing drag times then RMF is good enough.

good info from experience, do you have any dynos, or is this just from how it feels?

my impression was that toda headers also gave the best top end power as well out of all the bseries headers.

Normal Toda 4-2-1's are too small for a b20, maybe a standard build like mine is okay, but if your planning on working it. Id suggest either trying to find a real RMF or SMSP header

woah. really

[GSi_PSi]

Even the RMF replica is too smalll for a built b20... to totally get everything out of it you need a real rmf, there is a big difference in size with fake vs real... ie
REAL RMF

I wish i had the money otherwise id go and snap this header up right now.... its on ebay.

Aaaaaaaaaaaand thats about enough bullshit...
In the real world, off the shelf TODA headers are good for 150~160kw at the wheels when used on a built 2.0L B20 or B18.
So... Hands up all those who've built & tuned engines like that....
Anyone?

Agreed... His acuracty is further improved by stating what he recons; as fact.
This is most effective when he hasn't actully used any of the parts in question...
