i have a 93 civic 4dr and del sol, both have vtec engines. on my 4dr the vtec pulls very hard at 5200 rpm. My del sol just kinda gets a little faster. I had a friend who is really into honda stuff drive my 4dr dx(he has a 4dr ex). Since he was used to driving with one hand on the wheel from his standard he said he almost lost control when the wheel pulled in vtec mode. He also never seen a vtec motor pull that hard when in vtec. I first thought it was my MSD that I put on it. so i moved the MSD to the del sol hoping for that same pull, but nothing. I dont have much info on this engine other than its a d15z1 from an old vx. Any ideas why it would pull so much more? Im kinda thinking the cam on it may have been changed. this engine had a few mods done to it before i got it. that I am sure of.


please ignore grammar, its 5am and i havnt been to bed yet.

 

The D15Z1 is a pathetic engine, it's not truely even VTEC; it's VTEC-E. It mosty deactives one intake valve per cylinder at lower RPM's to run like a 12v, and locks them in to act like a standard 16v up in the higher RPM's. It comes from the Civic VX (92hp.) The only cam you can get for this engine would be a regrind, as well as a waste of time and money.

The standard VTEC system in the Sol runs a normal cam profile at low RPM, and a more aggressive profile at high RPM. Your Sol's engine (D16Z6, used in the del Sol Si, Civic EX and Si) is MUCH more powerful then your Civic's Z1 at 125hp.

If your friend is loosing control of a 92 horspower car... I feel sorry for him.

 

Something's not right here. Why would someone swap a VX engine into a sedan? I don't remember what engines EG ferios had, but didn't they have more than 92 hp?

 

Either a 102hp D15B7 or a 125hp D16Z6.

 

HAHAHAHAHAHAHA OMG...... Ok I have a 94 EX D16Z6, with a cam, and other stuff, My wheel pulls to the left when I race, the only way you can lose control of it is if you let go or have been yanking it in your car with alot of lube.....Thats all I have to say... I have never lost control of a FWD car, HOW? Is that even possible?

 

it just pulled to one side and made him freak out. serously, in vtec it pulls hard. i only swapped with this one cuz my old stock dx motor blew and i was in a bind. so 100$ later i had a vtec engine. (vtec-e) it spins the tires under heavy acceleration in 2nd, and its auto.

 

Wow, your car must weigh 900 lbs, because spinning tires with a 92hp VTEC-E motor is neat, definetly. Are the tires in good condition....?

Anyway , a broken motor mount and bad alignment might cause it to pull as well... because with my B series it doesnt pull enough to make me lose control..

 

Definetly possible, although much tougher as we suffer from understeer usually..

 

I'm sorry (not really,) but that's the stupidest thing I've heard in a long time. A D15Z1, mated to an auto trans, would be lucky to make 60 wheel horsepower. That's like saying you loose traction on a ride-on lawnmower.

 

Sure you can. Ever heard of power-off oversteer?
