whats the best SOHC motor out worth building and in the future, boosting after motor is built? it can be VTEC or not im juss wondering bc i wanna be different than all those who have DOHC, even tho its better, i juss wanna be different.....

 

I think thats a matter of opinion and money. I personally like the Z6 and the A6. Decent little engines, lots of available parts, and can be made to put out a healthy amount of HP.

 

Any of the 1.6L d series engines are good. d16z6 d16y8 d16a6

 

I would say the JDM d15b Vtec.

 

IMO the d16y8 is the best SOHC motor, of course I only say that because it has the best tranny (if u buy a full swap)

 

Problem is the d16y8 hydro trans does not swap into the ed chassis without heavy modification and fab work.

 

i heard that the d16a6 has the best block because of the girdle...anyone want to confirm this?

 

I've heard the A6 is the best block because it has the strongest rods. Don't quote me on that, but either way the A6 is awesome, just couple that with a Y8 head and you'll have lotsa fun!

 

My vote goes for the D16Z6 out of the old Si's and EX's.

 

In stock form? The Y8.

in stock form with boost or NoS - Z6 or A6.

In BUILT form... probably the Z6.

 

i had a stock A8 in my Si hatch and i blown it up with a 55 shot, now i have a Y8 with the 55 shot on it and i LOVE IT!!!

 

so yall are sayin probably block wise, go with the A6 and head wise probably go with the Y8? thats cool.

but i personally like my D16A6, even tho its a single, ***** mad quick......

 

ok heres another question?????

if you were to boost, stock wise, what would you swap into your 90?........

and juss for future reference, what are the engine codes for the SOHC VTEC motors, isnt it just D15B i aint sure..?

 

 

I thought the A6 rods were more beefy than the z6?

If you are going to boost a stock engine, I would go with the strongest rods, the A6...

Plus, with an A6 you don't have to mess with wiring up VTEC or OBD1...

All the other 90+ A6, Z6 and Y8s have a solid 1 peice aluminum girdle. I think the best motor combo for a build and boosted D16 would be a A6 block and a ported Z6 head (not the Y8 becasue the chamber is small thus it raises the static compression ratio a bit more)

edit: forgot that the 1st gen ZCs have the thickest stock rods on the D16s but they are VERY hard to find

 

I would have to say the D15B VTEC is the BEST of all SOHC motors IMO.

 

Boosted A6 gets my vote.

Good luck man.

 

i like my girls like my cars with d's not b's

 

how about a sohc zc. they have a more agressive cam and are the same as an a6.

 

d16y8 is great if you enjoy spinning main bearings!

my vote is for the d16z6 or d15b vtec.

 

For boost....low mileage y7 maybe y8 or a6 (w/ whatever mi.) ? Theres less other parts to buy if i go with the a6 right?

thx

 

I'm not 100% sure one this, just what I've heard. But I heard that the D series motors arn't great on boost with a stock bottom end because they have much weaker rods/pistons than most B series.

I'm not 100% sure of that, just one of the things I've heard on HT

 

ive ran 12psi no problems on a z6... i keep 6psi on it daily
