Best engine for boost?
 

Which Honda/Acura engine is best suitable for boost when built? most reliable?

d16 in oem form. if you're a b guy, then B18C1 (gsr), but i wouldnt push the # of PSI you run. then again, with boost, it's always a good idea to sleeve the block...

This one is an obvious answer.... the k-series.
A stock K24 bottom end with a k20 head on a gt30 hit around 700 in stock form before blowing a pee sized hole in cylinder 3 while pushing it further on the dyno. I am a beleiver in K series engine, but can definately be out of budget for some people.

^^^ K is good, but i think you can get alot farther with a b or d for 9 grand.

we weren't talking budget, but with that in mind then yes i agree with you.

the answers to this question are so subjective, do you prefer a large displacement and lots of torque or are you good with little displacement on small torque... High end would be a B20 bottom end with B16 type R head or for smaller displacement go with a B16 withe type r head. both are proven to be performers that display durability

i got owned!

yea, i forgot budget wasnt a factor. k all the way then.

B18C:smilie_da

it also depends on ur budget and hp/ 1/4 mile times you want to hit.

would anywhere in the 12 secodns be attainable at about 250whp/200tq on a boosted b16 in an eg with slicks? i know its a very vauge question but im just looking for a rough idea

i dont see y not

I call :bs: on this one. Your not going to make 700hp with a 52lb/min turbo. The turbo simply doesn't flow enough air for that kind of power.

hahahahhahahahahahahhahahahha 700 hp stock....ahahahah what happeneds to the valve springs at that boost level... they would float the valves and youd be lucky to rev the car past 3000 rpm lol!!!!!
K20 .. if this were the case ... im not even gonna get into it....

stock d16z6 boost it to 17psi, sounds lovely...or build it a bit to handle higher psi easy 12's

I saw the k20 that did that. there is a vidoe floating around, they were basically seeing how much they could get out before it blew and they ended up getting like 42psi and like 680whp or something rediculous.

i love the b18a/b personally but to each they're own i guess

Alright well i can show you vids and links of the car if you like.... i couldn;t beleive it myself. Here is a link from k20a.org! Look at his sig 654 my appologies, but i swear i saw it spike and hit 41psi and make very close to 700 as another user just mentioned. Here is the car in action aswell!

It doesn't get good until the end...


Ummm, this goes to show you don't the capabilities of any stock valve spring or what even valve float means. You need to realize actually how much tension a valve spring actually has. Valve float happens at high revolutions where the valve spring can't keep momentum and actually the llifters loose contact with the cam lobe.

The best engine for boost is the one you build for boost...lol.

+1 can't argue that
