Acceleration Issue

I dream of BOOST
I have a 93 del d15. When the car starts off it usually has no power until it get to around 4500 rpm. would a sr intake help eleviate the issue or would it be a problem with a sensor or just a worn out 156000 mile d15, thanks :confused:
 
you cant expect that much power from a 1.5 down low anyway. did you just get the car or something? or is this a new occurance with it?
 
Just got the car, this dude thought it need a clutch, it wouldnt even drive so he gave it to me for free...... I took it home and checked the fluids for the hell of it. It just needed Cluthch fluid!

i cleaned the points on the cap and rotor and slaped on a sr intake. It gave it better throttle response when i start off. But there still is a lingering problem with acceleration, Almost like maybe there is a fuel problem, its real signifigant even for a d15. It feels almost like its starving or getting flooded without the smell of gas. I will be junking the motor and trans soon and doing a swap to a b18c5 or if I'm lucky enough a b18c spec R series but until mid summer i still want to enjoy the car as is, i cant figure out if it may be a tps or other sensor, like most of us if when there is a slight stupid prob with our cars it drives us nuts until we figure it out, so any off the wall ideas could be helpfull. :D

Yea my car leaks clutch fluid every time I hit vtech. Try the royal purple synthetic clutch fluid it works gr8!!!!!

vtec and clutch fluid have nothing to do in comon. unless your not closing the lid on your clutch fluid resiviour. wowwwww you've got to be kidding me.

But in all seriousness now, you never told us if there is a check engine light. Ignition timing could also be the culprit.
 
There is no lights on, but funny you ask, i just talked to guy that gave it to me. He said it got a new timing belt/chain and this is when an acceleration issued started for him, but for him it was around and after 4000 rpm, since i have been driving it it is before 4000 rpm sometimes and never after, when it gets around 4000 it takes off like it were a vtec but its not its a d15, so maybe the timing should be adjusted, last time i used a timing light was on my 91 acura ls and i dont really remember how i did it to fix it that was 10 years ago and a first and last
 
No the b18c5 is a usdm with 195 HP at 7800 Rpm and a b18c spec R is a JDM version with 210 HP at 8100 RPM and they both have different compression ratios both engines are found in the 97 -2000 integra type R but produced in different countrys

Well now that you say that the problem started right after the timing belt change, it makes me believe that the cam timing is off a tooth or 2. Rotate the crank pulley to the TDC mark is alligned with the marker on the lower timing cover. Pull the upper timing cover and make sure the cam is also at TDC.
 
Thanks I'll give it a try tomorrow and see if it ligns up. If not is there a solution without taking the chain off or is it a matter of just advancing the timing if at all possable.
 
First check the ignition timing. It should be set to 16 degrees btdc (at least thats what it is on my 18c.) If that doesn't fix it check the cam timing. If it is off, you need to pull the belt off and reinstall it when everything is alligned correctly.
 
thanks bro I'll check it out, sounds odd to say but i hope thats it, its cheaper to fix that than having to replace parts.
 
It was raining today so i couldnt mess with it but i did scrub off some grease from the block and seen that its a d15b7, wow i never drove anything with a little over 100 HP... so i thought, its funny i used to have a 95 deli sohc vtech D15Z1, it's funny how my 93 non vtech seems faster i was always trained to believe through hype that sohc vtech had better hp and torque specs than non vtech sohc. quess i was wrong............
 
the vtec motor has more power, the non vtec motor has different gearing in the trans to make it feel like it has more power

Actually the non-vtec d-series motors come with even taller gears than the vtec engines. This is because they are purely for gas mileage.
