New K-Tec Manifold

[singlespeed]

if i remember rightly i think it was 395+ vat for the manifold and its 63mm?

you could be right

Would someone be able to guess what the differences in performance would be between this one and the one Yotah has? As they are two totally different designs, both must have been built with a certain reason or particular area to improve performance on..

Plus a significant price difference.

thats the thing, it would just be a guess and even comparing rolling road figures is meaningless unless its the same car on the same rollers and same conditions.

Do some reading up on exhaust merge collector design and have a guess yourself.

The K-Tec / Janspeed was built to fit the car, instead of a copy of the RS manifold, which was a good design to meet all the emissions, cost and assembly constraints.

This is our Twingo RS with our new 2.5" bore system, sports cat and tubular manifold. Available to order from July.

Just saw/heard it on facebook. The sound is not too loud for my likings. I could be well tempted if I once manage to save some cash!

just asked Ktec for an update on facebook, the system has started to be produced this week.

My first thoughts when I say the subject of this topic was: "Yes! A R2 / R2 EVO replica", but it looks totally different. I could be good, but I've heard the R2 / R2 EVO is stunningly good, tested and proved for 160 or 190 (an anything in between), too bad of the expensive price: 3.000 euro's in Holland for a complete exhaust and massive CAT, all from Renault Sport!

The R2 / R2 EVO exhaust:

Based on the R2 I would say that the exhaust (and especially the manifold and big sized CAT) and airbox are the parts to have (or to be looked after) when modifying? That probably means at least the specially designed "RS" inlet manifold is good enough to start with?

But after all, it is amazing to see how the first CRX VTI's produced 160 bhp and the CAT version between 150-155 bhp and the first Civic Type-R made 180 bhp! All from stock!

The civics didnt have to pass nowadays emmissions regulations...

Aren't the CTR engines hand finished and also have variable valve timing on both inlet and exhaust unlike the 1.6 K4M. The spec isn't exactly run of the mill stock engine, having a limit of 9000rpm

I think that you shouldn't worry about the k-tec manifold not being a exact copy of the r2 manifold. I mean, the R2 manifold looks to be designed to improve performance at the top-end rev's. So not ideal for fast road use. But i'm not an exhaust specialist at all, so I might be completely wrong regarding to the R2 manifold.

 

[mazmaz]

in fact normaly it's said 4-2-1 manifold are for power at low rpm (so the R2 one) and the 4-1 for power at High RPM (so the original or ktec one)...

But R2 power is at High rpm ....

so that complicated... or maybe the R2 picture is not the REAL R2 manifold
this is just a drawing !

 

[1975DCS]

From what I have heard the manifold is high tech made, with tube all the way down to half the car, then followed by a massive CAT... We don't know the complete secrets of the R2 engine, but since torque is up to 180 Nm it could be great balance of power and torque. Maybe the pipe diameters also are different of each piece of the manifold in comparison with the K-tec one? Maybe a R2 could throw out 170 bhp and 170 Nm on the K-tec one? Nobody knows... But since the R2 manifold is good for up to 190 bhp and 180 Nm, it is at least a good design... That doesn't mean it would work on a original engine, but I do wonder what it could do on a standard engine with R2 air box, but without pistons, flywheel and camshaft, or in other words without opening the engine itself...

The original CTR had a 1.6 with the original, simpler VTEC, not the fully-variable iVTEC on the K20.

 

[singlespeed]

Now avaliable as manifold, complete system with/without cat or downpipe back. Just look for the different listings...

That's Sexy! and a decent price tag for full exhaust

 

[maggi200]

How can it have a WAS price, if it has only just been listed?

 

[frediiii]

20 bhp with remap... that sounds too good to be true

 

[yotah1]

Yeah, sounds like a lot of HP gain only with an exhaust, but as usual, we would have to get the parts on a car to check it at different dynos...

I'll see in October how much the decat helped me get out of the 1.6 since the last remap.
