Yes, it's true. The loss of low end is there, and it sucks. It feels exactly like if you were to have the secondaries always open on the stock GSR manifold. What can be done to make this up? I plan on getting CTR cams and a chipped P28 ECU. Will this make up the difference. Is the loss of power just due to the fuel maps in the ECU or something else?

Anybody have similar experiences with this manifold, and what did you do to fix it?

 

Your Stock ECU is whats killing you.

 

There isn't much to do. I saw dynos of a gsr and type r and the type r suffered in the low end.

 

the r cams will make up for most of the lost power, they work well with a single runner and have a nice chunky midrange.

 

oh BTW how was it installing it? I need to install mine soon. thanks?

 

u sacrifice some low end for some high end when it comes to skunk2 intake manifolds. no way to increase your low end... unless u slap on a greddy turbo kit on your car.

 

you need to get a new ecu.

 

yes the ecu needs replacement or chipped

 

Getting the old manifold isnt that hard if you got the right tools, but if you don't, then good luck. There is so much less to the Skunk2 manifold then the stock one. Here are some pics




This is what i had to use to get to the mounts underneath the stock manifold!


All installed

 

how's your top end?

 

what else do you have done to your car?

you will need other upgrades along with tuning to see the benefit of the

skunk intake manifold over the stock gsr one.

 

I am not surprised, you are sacrificing intake velocity for intake capacity. That is going to result in worse low end, but better high end. Not great for daily driving, but great for strip/autox/track.

 

isn't the lost in lowend caused by the shorter intake runner's

 

get that p28 chipped, raise the rev limiter and when you shift you'll be at a higher rpm, therefore less lost power and you'll optimize the potential of the skunk 2 manifold, where all the power lies up top.

 

skunk 2 intake mani + stock cams + no VAFC = poop

 

Just got my Skunk2 manifold installed with 00 Type R cams, AEM intake and P08 chipped ecu. I was worried about losing the low end and when I first drove it, there was some loss with the Mugen chip(Vtec 5700 rpm). It pulled amazingly once in VTEC but there was a slight dip around 5000 rpm. I was a bit disappointed but then I switched to the Skunk2 chip (VTEC 4800 rpm). Wow!!! Car pulled amazingly and the lower VTEC point seemed to do the trick. Car feels like it only loses a little low end power but the pull to 9000 rpm is awesome. I still need to try the PYR and Vision chip but I think the Skunk2 chip is perfect!!

 

Updates on chip and Skunk2 manifold install. Just got back from the track today and of course the new found power was too good to be true. Car was running unbelievably fast. Then into the next half an hour session, boom, blew up the motor and massive black smoke behind me. Car must have been running very lean but that is only speculation right now. For sure the motor is gone. Can't even remove the #3 cylinder spark plug. Now trying to decide what to do. Buy another JDM GSR motor, get a domestic one and rebuild with CTR pistons? I guess the lesson I learned is to definetly get an air/ fuel ratio gauge. Damn, I was shifting at an indicated 8500 rpm(probably 8300 rpm).

Does anyone here know where I can get a good low mileage JDM B18C motor. I definetly need the higher compression...

 

Did you fortify the internals to be able to deal with the higher RPM's? ie - stiffer valve springs. Also, did you get the car tuned with a VAFC or some type of fuel controller?

Sorry to hear you blew the engine.

 

Yes, I got Type R valve springs. Since I was only planning to run a basic Type R setup, I just went with a chip designed for the Type R, Skunk2 and Mugen chips are both designed for stock internals. Since I was only reving around 8500 rpm I thought everything would be fine. My setup is similar to a Type R. 10.6 compression, single runner intake, type r cams and valvetrain. I am wondering if I these programs ran too lean at some rpm and caused the detonation. I am still pissed at myself for not getting an A/F gauge installed. I did not have time to tune and since I was using a very mild program , I thought everything would work properly.

 

did you have a fuel pressure regulator?

 

you need an ecu from either an ITR or a B16A. these are sindle runner mani ecu's. this will balance the mid out for ya. this is pretty common..... now if you get r cams and the r ecu youll be doin pretty good....

 

I did have a Type R ecu. I had a P08 ecu chipped with a Mugen and Skunk2 programs. I was using the Skunk2 program when the motor blew. Both these programs were designed for Stock type R cams and single runner intakes. That is why I said it was running very strong. I did not have a fuel pressure regulator as the ECU would have the fuel set for the type r cams..

 

Sorry about your car dude.... as far as loosing low end power I must say that since I got my t/b sealing issue almost resolved the the low end that you lose (which I don't think is much) is well worth it. The mid to high end just flat out kicks asre. With my Vericom I now do the 1/4 in 14.8 with 17" street tires which is about 3 tenths quicker then my usual 15.1. That does not tell the whole story though, the car is MUCH more powerful from 80mph to 130, it is a light and day change. To those of you who are wanting to buy one, do it. I don't see any downfalls to using this manifold.

Agree, Skunk2 manifold is an awesome upgrade as long as you have the ITR or similar cams and the proper tuning or ecu. I would do it all again and will so I will start another post to address my situation.

 

You know.... I just don't see how the ECU did that to your car. Have you found out why it let go?
