Which one is the better header for the Toda B's...Did the "great header test" but the test was only done on stk itr cams...What u think..can't loose on Mugen right..

thanks

out of all the headers you listed the Mugen is by far the most least used, and archaiac design.

I think Mugen is good quality, but you can get alot more power from a SMS, for less money

 

Has anyone ever dynoed a Mugen 4-2-1? I've seen 4-1 dynos but it's not right to compare 4-1 to 4-2-1's as they both got there advantages and dis advantages.

I myself like Toda and Spoon headers but SMSP header runs neck to neck with the Toda from what I saw in dyno charts. I figure the Mugen 4-2-1 would be somewhere close but under the spoon header performance wise due to the older design. The hytech is top performer from what I seen in the dyno testing done overlast yr but it's not much better I believe it was 3-4whp in topend over the SMSP and Toda headers but I know simple heat coating of the Toda header can give you those extra hp back and close up the gap on the top end.

I guess it will depend on what you plan to use the car for? drag or road race or just everyday driving?

 

I always thought smsp outperformed Toda...can anyone confirm this?

 

Well I forgot who had all the dyno plots online but I know it was tied or close to within 1-2whp of each other. Though I could gotten it backwards but I know it basically tied one of the independent header makes from the US.
But I know there around on someones website I can't find them as I apparently deleted my link to it.

 

Found it I thought it was SMSP and Toda both got 190whp on top end according to the dyno testing they did back then.
Here was the last one they did that compared the two.

 

Cool nice graph plot....anyone know where they sell Toda Headers and how much they are?

 

I asked this way back, but know one replied, but who has the air/fuel ratios for the great header test, and also I want to know the order that each of the headers were tested? Can someone help me out....

 

I would posted this up back then if I saw your post. I believe the folks that did the testing should be able to tell you all the finer detials of the test.

 

If you are leaning towards the Mugen, you should really think about the stainless DC JDM. The Mugen has 45mm or 1.77" primaries (like almost every JDM header except the ITR) and DC has 1.75". There primary lengths are very close but I feel the collector is actually better in the DC than the Mugen. Ground clearance between the 2 are probably very similar since the tube layouts are almost identical. BTW, all the JDM 4-2-1 headers use 45mm primaries and 50mm secondaries.

 

They're around $975 or so I beleive. www.todaracing.com/dealer.html

 

One big advantage of the Toda is the ground clearence. I am not sure you can use the header results to decide which header is best for Toda B's, because the tests were done on a relatively stock car. But I guess you can't go wrong with Toda header with Toda cams.

 

Toda and SMSP showna very aggressive top end power. If you want more top end power then consider the above.

Spoon has the most torque at the mid-range which means more useful power for daily driver or Auto-xers.

Since nobody have made a header test with Toda Bs with tuning so it is very hard to say cuz those plots are dynoed from a stock B18C Motor.

Different I/E combo sure will effect the results . I have been installing a lot of Toda B cams with Spoon / Mugen421 / T.1 header with tuning you will see about 185-190 ranges.

The figures are based on:
-B18C5 motor
-Toda B / Spoon camgears
-stock valvetrain / injectors
-Spoon filter
-header (either one above)
-stock b-pipe
-Spoon N1 muffler
-test pipe
-VAFC
