    I'd say then you should first give it a full service. It might be worth changing the leads. Fill it up with superunleaded, add a redex treatment and take it for a long motorway run. This should help clear out all the crud.

    Is the Safc a fuel/airflow piggy back computer? It might be worth taking this off to see if this is causing the problem. It might be running lean or rich causing a loss of power.

    2nd to suggest service.the vtec is contorled by oil pressure, if the oil is oil and thick it wont work as well. hopefully prevec will be on latter as theres filter for the vtex as well this can become clogged so the vtecs not coming on properly

    Not heard of any catch tanks having a valve tbh. Empty that as well. Air should be allowed to escape from it via one of those little filters, or back into the intake where your oil breather used to connect to.

    if the filters parcially blocked by gunk then it might not be locking the pin in the correct place.
    soilinoid can still open and close as this depends on revs

    could a blockage in the exhaust system cause this.Maybe it could be backing up as the power builds up?

    170 standard jap spec yes its a arc induction kit has a panel filter not a cone look it up its a expensive bit of kit but very good (jap) had the cat taken off much better vtec is alot better now aswell but not as good as it should be charlie from pro speed told me some1 has messed with the timing bcoz there was a seal broken and advised me to go to some1 that duz crypton tuning. so now i have a arc induction kit jasma 4 2 1 manifold prospeed de cat and a cat bak janspeed exhaust. any1 wana buy a apexi safc? needs setting up tho comes with harness for the ecu and the controler.

    hi mate, i havent been on in awhile

    my brother has the del-sol also and to be honest, a sir civic has that little bit extra kick in vtec, the del-sol is quick by all means, just not as fast as a sir, same b16a engines i know, but its like the civic sir is tuned that little bit extra

    as for the timing, they need to be pretty bang on, kind of right wont do
    who checked it??, you need to bring it to a garage and they will pull out the rubber block on the gearbox, and check it with an ultra voilet lamp, but id say its ok

    i will say though, when i had the timing belt changed on my type r, it was put on extra tight, and i noticed it was restricting the car, it might be that

    seeming you only bought it, change the timing belt anyway, and get all the kit
    at least thats out of the way

    all the mods you have will make a differance, but remember that the civic sir will always be quicker, the del-sol has a huge motor for that roof and thats alot of weight aswell

    pg is right about hard to tune - high performance japs, the best vtec engine to tune and get the most bhp from is the esi 1.6 sohc, the buddys are all the time moddind them and believe it or not they are keeping up with dohc

    by the way welcome to torquecars and how much for that safc??
    and did you clean out that filter by the vtec solonoid?? they need to be kept free of anything, especially sloggy oil(only built up due to not servicing on time)

    Hitting 200-220bhp with the B16 can be done, but will take some work. Get rid of the 4-2-1 manifold and get yourself a 4-1 instead. If you want Type R cams then look at taking parts from the EK9 (Civic Type R) as the engine is the same. After this you should be closer to your target. Once everything is done you can have it remapped as well.
