Tegiwa Manifold


I have a Tegiwa TODA v2 replica fitted on my EK4 (b16a2)

Welds look good.
Ground clearance is good.
I really feel the car's stronger from about 3k rpm and all the way up to the redline. Although I expected it to be just a tad more aggresive when the vtec engaged, sadly it was dissapointing.
Anyway, its a great header which also is an eye-catcher under the bonnet :)

Don't have any results of the power increase on paper but will have soon!
The EK4 is going to be tested on a dyno in about 2 weeks. I'll post the results later.

My current set up:
Exhaust
Tegiwa TODA v2 rep. header.
2.5" SRS testpipe
Jasma Mugen twinloop catback system

Intake
Spoon drop in panel air-filter
Spoon kevlar airflow pipe

Cheers :)

Got any pics??
I think to make the best power on a b16a2 you will need mapping.

No pics yet :X
Will post some asap!

I've read about mapping for the best results but I don't think my overall setup is ready for some mapping yet. Maybe in the future!
 
If you get a DC sports one dont get ceramic, because its just mild steel with a ceramic coating which will rust like hell on our salty roads, i'd go for the DC Sports stainless steel, delivered for £300 isnt bad - still a lot of money for a 5-10hp gain though

Funky Power also do a greddy manifold for b series for £400 delivered, no idea what gain its has and what the build quality etc is like however
 
had a greddy on my jordan, good gains, but probably not for ek9 as mine had 2.25" collector anyway

The Mugen catback just ruins your hp gains with those headers...:angry2:

Pretty much the same as this, i had to check if the vtec was working!
Really subtle at low revs with my Mugen twinloop, and the OEM 96 spec manifold has a very noticable vtec crossover, can hardly notice it on the tegiwa one, but i'll get over it if the gains are that good...

How did you find the fitment?

Just remember a smooth crossover is not always a bad thing ;)
 
definitly a good thing in my book

consistant power all through the rev range

If its BHP your after 4-1 is your friend - also on a B18C i think is the best manifold - for a B16B you might be better with a 4-2-1 for the midrange torque.

I disagree, the B16B is designed for top end power, best to build on this strength instead of detracting from it to prop up its weakness in the midrange.

100% agree!

All those people complaining about the lack of torque on the b16b!
If i wanted torque i would have bought an ep3, I love keeping the rev needle dancing and the engine singing in order to drive my 9 fast, it just adds to the experience and makes it 100 times more exciting then driving other type r's IMO.

I prefer the b16b to the b18c purely for the theatrics of driving my 9 with a high pitched whine all the way up to 9K-ish!
 
So people are finding vtec crosssover not as agressive?

Is this an actual loss in top end power or due to increased midrange.

Any of these Tegiwa manifolds been dyno'd as I've just put a deposit down on an s300 ecu and am unsure whether to risk buying a Tegiwa manifold or go for something else.
They certainly look the part though....
 
we dyno'd it and it made 7.2bhp over 98spec HDM

Two more dyno's on b16a's in Portugal
One made 5.4whp, the other 9.1bhp
 
Ok I give in....just ordered one from you're website.

Should be a couple of weeks before I get it fit and the car dyno'd and I'll post results here.

Please make mine extra shiney BTW :)
 
is there no dyno graphs to compare this to other manifolds? peak figures aren't everything!

I agree. When I get the car tuned with the S300 I'm really going to be looking to having the Vtec coming in at a slightly lower RPM and a little more torque through the midrange.

Peak figures I'm not concerned with, unless I lose power over stock figures.
 
Had this manifold fitted for a few weeks now, also fitted a Tegiwa sports cat at the same time.

As other people have said the car feels so much stronger from 3k rpm onwards, but I find vtec crossover is still as agressive. Overall it is a big improvement over the whole rev range.

Thanks to Tegiwa for another good product!
