Boost on a Built D Series
 

Im planning on boosting my d16y7 with a custom 14b kit intercooled. I was wondering if the block is built. Rods, sleves, etc (obviously with fuel mods). How much boost can it actually handle before it pops? I want a low 13sec car (or less), and if it's not going to boost too well then I might as well swap a b20 then boost. Would lowering compression to say 9:1 be a smart move?

Also is the 1gen bov just as good as an aftermarket. Or is there much of an performance difference?

Re:Boost on a Built D Series
 

I would say that safely, you could run about 12psi with proper fuel management. Anything above that.. and your punish it a bit. As long as you have no detonation you should be fine with 12psi.

What about on dropped compression?

Re:Boost on a Built D Series
 

With a built block, pistons/sleeves/rods your boost is going to be limited by how well your car is tuned. You could easily run 20psi on a setup like that, as long as you have properly sized injectors and a kick ass engine management setup.

I think 13's would not be a problem..

:) dont recommend it but it would be my choice...

Re:Boost on a Built D Series
 

what engine management would you guys suggest for around 20psi setup? With proper fuel of course.

Off topic, I apologize.. but PMs bother me. :(

Anyway.. Boosted, your URL in your siggie doesn't resolve, is it correct? ..or is it just down?

Re:Boost on a Built D Series
 

fixed ;D

Re:Boost on a Built D Series
 

no need to build to hit 13's. My boy hit a 13.2 on slicks in a 2000 CX hatch
T3/T4
FMU
SAAB Intercooler
Piping by volvo
fuel pump
10PSI

13's all day long.

Re:Boost on a Built D Series
 

If all you want to run is 13s, why would you waste your money on building it.. unless you have a ---- load of miles on the motor, I would rather spend the money on a good stand alone and some injectors then get it tuned by someone who knows what they're doing..
I forgot to mention a timming retard, it would also help..

Re:Boost on a Built D Series
 

lol, you should see my box.. haha

indeed, you dont need to build the bottom end for 13's at all. Good traction, decent turbo setup and a good driver, piece of cake!

Re:Boost on a Built D Series
 

well I really want 13 or lower. So built gives me that ability to go lower. ;)

Re:Boost on a Built D Series
 

no need to rebuild if its old, i have over 160000 miles of pure asswhoopin on my motor and now its boosted

Re:Boost on a Built D Series
 

my buddy Neal is running stock D16a6 internals on a stock, never been touched engine 13psi intercooled with a greddykit and just broke 13.8

-H

Re:Boost on a Built D Series
 

13.8 with 13psi :P
thats alot of boost for a high 13 sec run..
you should be in the low 13s
do you not get traction or what??

Re:Boost on a Built D Series
 

Ya.. that's got to be bad driving..

Either that or his motor blew out at the end of the run. ;D

Re:Boost on a Built D Series
 

13psi on an a6 you should be in the 12's a guy i know an 89 si it's sold now. but anyway 75 shot i/h/e 13.4 on slicks
