i bought a 89 civic 1.5 dual point (Vin 2HGED) and it has a four speed what is this all about can i use it on other cars is it ne better what the down low on this trans.

Thanks alot.

 

Dose ney one ever heard of this help please

 

Basically you have a 5 speed transmission minus the overdrive...
Overdrive is great for highway driving... I think these transmissions were just mainly intended for around towning...

Yes, it will work on other cars with the D series engine. WHy would you want to? In a bind or desperation I suppose. I would rather have the 5 speed.

I have another 4 speed if you would like to pay shipping for it.
Matter of fact, I have a lot of D series stuff...

ok so for drag strip racing a 4 speed would be better but are the ratios the same as the normale 5 speed that i have for the d serise engines

thanks

 

the ratios are different in the 5 spd than the 4 the 5 has shorter gears. when i had my 4 spd in second i could hit 60mph but with my 5 spd i hit the rev limiter @ like 55-56mph (i dont have a tach so i have to rely on my speedometer and noise from the engine)

 

Std 4sp 1st gear ~= Si 5sp 1st
Std 4sp 4th gear ~= Si 5sp 5th

In a normal Honda engine where you need to keep the rpms up the Si 5sp is a much better choice.

I have heard of some turbo'd guys using the 4sp trans in order to keep the turbo spooled for a longer period of time.
