i have a 88 hatch with a first gen b16a swap im running a pr3 ecu, password jdm intake,dc 4-2-1 header,ctr crank pulley,invidia exhaust,test pipe,proffesional products 68mm throttle body. now the car runs fine under normal driving but when u throw third gear it takes alot longer than expected to climb speed wise and it seems as if the car has more power in the low end than up top any ideas?

 

bump

 

its a b16, did you expect it to rip through gears like a formula car? lol.

 

hahaha, thats what I was thinking exactly, until he said it seems to have lost top end power

if its only third gear, maybe its a tranny problem, correct me if im wrong somebody

 

ls tranny?

 

y1 cable tranny and no i didnt expect an f1 car just every b16 ive ever been in has good top end and mine doesnt it pulls hard in first and second but seems doggy in 3rd and fourth. fourth is better than third tho

 

may be its the tranny you sure its a b16 tranny not a ls?

 

when you shift do you drop out of vtec? what size tires are you running?

 

its a y1 b16 tranny for sure and im runnin 17's at the moment cause thats all i had 15"s coming in july

hummmmmmmmm

 

i know i know lol im not a ricer, its just all i had at the moment to get it on the road.

 

you may wanna try and get the car on a dyno and make a 3rd and 4th gear pull to see wha your AFR's look like... i know its not a reall 100% load like on the street but it should give you an idea as to whats going on...

X2 agreed.

Tuning is key. Looks like you have enough power adders to where the stock ecu can't cut it anymore.

 

any clutch slippage?

 

no all of a sudden im throwin a knock sensor code 23 but the check engine light comes on only after u hit about 30mph could this be doin it? thanks alot guys for the help so far i appreciate it

 

68mm throttle body is far too big for an OBD-O B16 with (presumably) stock cams. I think you need a cam and valvetrain upgrade.

 

ok so somethings definately up i ran my buddys stock 2002 cavilier and he walked me down the highway so seriously guys what would make the car run like **** and yes i can drive lol. im throwin a knock sensor code only after 40mph tho and i have a small oil leak at my vtec spool valve. other than that i think everythings good, and it has the correct amount of oil in it i check it daily.

any input would be great

 

The knock sensor will servely retard timing. Thus, the reason you got walked. Go get it tuned.

 

just throw a 8 pack clutch with a lightened flywheel on there motor, and you'll be ripping the streets up like crazy lol

 

where can u get a knock sensor for an obdo b16?

 

knock sensor will retard timing like 9 degrees or more. making the motor fall on its face in vtec. That would do it. Ive got a few extras . someone closer that does honda swaps should have some. they are really expensive at the dealer.

what???? dont listen to this idiot. an exedy organic lutch is still good enough for what your running ind its puck *******

 

and if you do need a clutch they have this deal on hmotorsonline.com cusco clutch and flywheel-$300 for any b series tranny. you'll never find a deal like that

 

it has an exedy stage one clutch kit, how much for the knock sensor

 

call up like jhpusa or inline four. anybody that sell jdm motors and they might have one they will send you
