Just picked up a skunk2 pro series intake manifold and extended studs and the company i bought them from threw in a free hondata gasket. Now i have been doing some looking around for some information about installing the manifold but all i can find is information on obd2 cars. I drive a 95 Gsr and i would like to know if all my sensors will plug right in? and will it be a bolt on procedure? I have heard thousands of people say that blox is better and with skunk2 you will throw cel's but that is only with the obd2 right? Then i have also heard that if you install a skunk2 manifold you have to get it tuned. If you know or have any experience with the manifold please help

 

With any bolt on its "good" to get a tune afterwards to have your motor running at the optimum level, tons of people dont. I personally hate the skunk2 manifold. I dont know much about the blox but i have an aebs manifold and it was a very straight forward install. As long as its made for your model all the sensors should hook up just fine.

 

alright thanks for the help

 

if ur running a stock p72 ECU u might throw a CEL with the s2 manifold. not sure all i no is that u might wanna invest in a chipped p28 or something along the lines of a single runner ecu.

 

You really need a different ECU and some way to raise the VTEC crossover point to get the most out of a single-runner intake manifold. Cams and cam gears would be even better along that IM. The closer you get to being like the ITR intake/engine head/valvetrain, the more power you'll make.

 

well thank you guys for the help. After doing a little research i have found that if i throw a cel it is installed wrong and i can keep my stock ecu (all that from the skunk2 helpdesk) but it also says that i can use all my factory parts. I need to use the type r throttle cable and bracket though right?

 

You CAN use your stock ECU, but it's really not the best idea. Your stock ECU is tuned for the dual-runner IM, which is the reason why the VTEC crossover is so low compared to other B-series heads with single runner IM's. I'd be willing to bet you'd actually LOSE power in certain areas of the powerband by using a S2 IM with a stock P72 ECU and stock cams and everything.

 

he has a p28 ecu already not a p72, hes got an obd-1 integra

 

Did not see P28 mentioned anywhere earlier in this thread. Hence why I said it's not the best idea to run S2 IM with the stock ECU.

P28 ECU came with the 92-95 Civic OBD1 D16Z6 SOHC VTEC engine. All Integra B18C1 ECU's, be they OBD1, OBD2a, or OBD2b are labeled as P72, mainly because they all have the control for the IAB.

OP's car is a 95 GS-R, therefore OBD1, therefore OBD1 P72 ECU.

 

correct, because my old 95 gsr was OBD1 and it was running a P72

 

Where the heck did the OP say he has an P28, he clearly said he has his STOCK ecu, P28 came in Civic's not GSR's

 

yea man just PM me i have a 95 GSR and did the skunk2 pro manifold with the hondata gasket, yea p72 is a 0bd1 gsr ecu, p28 is civic, btw that hondata gasket was not worth it, sorry to tell you. mine blew out and dumped fluid after a year. but if you want info just message me about it. no cel's, running stock tune, gained .5 second in quarter mile time.

 

You gained HALF A SECOND just by swapping the intake manifold? Or did you do other stuff at the same time? That's like a 15-20 WHP increase given a stock Integra's weight. Seems pretty hard to believe.

 

no joke, i was running 15.6's, i changed the manifold, used a hondata gasket, and while i had the manifold off i put prothane inserts in my rear motor mount (motor was rocking and inserts rotted out) so i did those 3 things, few weeks later pulled a 15.1 at track. The 15.6 was was i had pulled maybe 6-7 times and i had been to the track 5-6 times with the car, did those mods, next time i went to track managed a 15.2, 15.3, and 15.1. So possilby the motor mounts being slammed out may have been causing a loss in power? who knows.

 

So you raced it almost 50 times and still couldn't manage to break a 15.6? My 200k 20 year old integra can do that. You sound like a liar/exaggerater to me, thats why I call BS. There is no way just bolting up a intake manifold gave you enough power to be .5 seconds faster. There are just too many variables to say that. How about taking it to a dyno so you can see the minimal gains in HP were lost in TQ, so they even each other out maybe giving you a little more top end. When are all these little ricer tuner boys going to learn that you actually have to do more than one bolt on to produce decent power?

 

Yeah does sound pretty hard to believe
