well i just bought a 1990 civic wagon with the rt4wd 6spd just wanted to know what u guys think would best a sohc vtec keeping the rt4wd system with a mild turbo kit or swap a ls motor in it? they are both aroungd the same price for me and i think the the sohc vtec with turbo and rt4wd would be funner what do u guys think?

 

LS VTEC ALL THA WAY BABY!!!

or turbo ls.....

DOHC's spool faster

 

turbo the sohc dont forget to get a head stud kit..4wd,200whp,turbo,

also check this video http://www.draglab.com/media/ShitBox%20A6.wmv

 

sohc turbo cheaper and way more rewarding when your leaving dohc in the dust. but either way you slice it. it will work out both ways but boost is more fun

 

You have a plan for getting that LS to work with your 4wd?

Good post right there. The LS won't work with that 4wd D series tranny. You would need a B to D plate, but then it might push the tranny out of alignment and make the 4wd not work still (rear driveshaft might get pushed out of allignment).

And the DOHC spools faster comment...where the hell did you get that one from? Don't beleive everything everyone tells you.

 

naw if i go single and turbo i keep the 4wd but if i choose l the i have to eliminate it

A larger displacement motor is going to spool faster due to greater exhaust flow.

 

If you were using the same sized turbo on both...but, is that a good idea?

 

I personally prefer built NA but without the 4wd you better off with a hatchback/crx.So just get a turbo and keep the 4wd

It depends. A smaller turbo will not make as much peak HP as a larger one. But it will be more daily drivable.

 

I realize that. I'm not going to dig out specs on turbo kits, but I assume the turbo you typically see on a d-series kit will be smaller than what you find in B-series kit.
But you're specifically talking about B vs D and the displacement advantage.
What if we're talking D vs D, like D16a6(sohc) and D16a9(dohc)? Does a "DOHC spool faster" than a sohc of the same displacement?

 

lol well does it? can anyone awenser

 

Yea I wanna know if what I was right....

No, a larger displacement motor will spool a turbo faster, dohc vs sohc wont matter for turbo spool aside from cam profile differences. But then its not exactly sohc vs dohc. A cammed sohc would spool a turbo <U>slightly</U> faster than a stock one. But were talking very minimal. Get a turbo for your application, which for you I would suggest a smaller turbo with quick spooling if your gonna rock the rt4wd, more power sooner ftw.

Plus if your not gonna build the motor your gonna sit around 200hp, which any small turbo will be capable of making. 8-10psi.

Depends on the turbo and the application.

I say either. Both would be fun.
