What do you guys think it will take to run 11s NA in a full interior DC2 frame DD?
I know you guys have seen plenty of my threads, but I don't think i've posted this up. Anyway,
So far I have
-RS Machine block, either 85.5mmOR86mm bore
-Eagle rods
-Balanced rotating assembly
-12.5ish:1 Compression
-p72 GSr head(going to be ported by member b20vtech)
-Stock valves
-Supertech valvetrain
-JUN3 Camshafts
-VictorX manifold(port-matched to TB and runners ported)
-440cc injectors
-70mm OMNI power TB
-Tri-Y bigtube rep.
-Stock exhaust w/ E cutout

Almost accumulated all parts except pistons, haven't bored yet, haven't ported the head yet, but for SURE these things will get done before the motor gets put together

I'm hoping for a power output of around 240ish to the wheels, but has anyone done a build like this with this big of a bore and daily driven(4-5 days/week, 20-45miles/day) and runs somewhere in the 11sec range??

 

Your biggest problem is weight, sure it'll rip but it's in a heavy car.. theres a 246whp I think it is GSR on youtube in a DC2 and only ran a 13.2? Not saying it isn't possible to be fast just really big expectations I think.

 

I think your going to need more then 240whp in a full weight DC to run high 11's. I'm thinking more along the lines of 260whp+. Others will chime in but that's a lofty goal for a heavy car.

 

Agreed, I wouldn't call that too streetable either lol? It's just not realistic.

 

Well, one of my team mates has an EG, civic CX (lightest model), gutted in the rear, and makes 24xhp and barely dipped an 11.99. Car wasn't fully dialed in but that was his personal best in the chassis. The DC2 is going to be a much heavier car and way harder to do the same thing in, not impossible though...

 

you can do 11sec on pump gas easily in a dc2....just boost it

 

Lol, this. Weight is deff your biggest obstacle.

 

around 375whp

if you actually want to do this you're in the wrong forum.

forced induction is a given with 2700lbs and 11s

if you were hell bent on all motor you have to go k24 or a dart blocked 2.2L stroker that produces 300whp, then you have to pray it's strong enough to break out of the 12s

at any rate you'll need slicks, stronger axles, a stronger clutch, bigger fuel pump and some way to control wheel hop. poly motor mounts are a good start

cheap way to do 11s? turbo a stock gsr, run slicks, big axles and an on off switch clutch. it will go for awhile before a gear goes or a rod breaks

 

Wow, guess Im aiming for too much? Whats the lightest anyone has seen the DC2 chassis go down to?
I know for sure that my last setup would've went high 12s pretty easily and that was a stock sleeved b20, RS machine itrs, stock rods, arp rod bolts, STOCK cast gsr head, cams, STREET tuned.
There is a hatchback here that runs mid-11s in a full interior EG chassis with my LAST setup and 230ish. BIG Props to him, but i've always heard that you dont need lots of power to go fast.
Anyway, Anyone think 250ish is achievable on pump gas? I KNOW that this current setup can go 12s easy, but i like to aim high Also, building this with a college student budget, so it's gonna take some time, but I think I have most of the major parts already.

As for making all this power stick to the ground, I just have the ES mount inserts and prothane inserts. Will DEF be investing in a simple/effective suspension setup. GSR trans for now, but a 4.7FD ITR is def a possibility.

Clutch is an Action 1-MD six puck unsprung. More than enough, i believe, to handle the torque this motor is gonna make.

If all else fails, nitrous FTW. But I would LOVE to build an all-motor beast. Only reason I didn't build for boost is because the sleeves being 85.5 already, I didn't want to risk it.

Anyway, more input is appreciated. Most of the knowledge I gain is from here, so you veterans, chime in!

 

85.5 is no big deal on a sleeved block designed for it

if you have a stock b20 this post isn't even worth repsonding to since it will fly apart the second you actually start making power with it. maybe not THE second, one guy on here even made one live a whole year. it's still a jinky *** rigged engine though

seriously though, order up a jdm gsr and turbo setup, instant 11s

this might wind up with a short life similar to the b20 but one of the locals got like 2 years and a LOT of racing out of a stock gsr with enough boost to crack 11s

that is if 11s are the goal, if you want to just do a wild all motor build that's different. still, sleeve the damn block if you haven't. when that thing comes apart it's going to cost you more than sleeving it will torn down. then again if you sleeve it boost is no problem.

at any rate that's my vote.

 

Its an RS machine sleeved block. And there are PLENTY of b20vtec that have lasted a long time plus have made a good amount of power on STOCK OEM sleeves.

Wont be boosting on this motor because even though its sleeved, the problem doesnt lie in the thickness of the sleeve, but the material in between each cylinder.

Anyhow, all-motor is what the plan is. I'll be happy if it dips into the low 12s, but satisfied and accomplished if it goes anywhere below 11.99999

 

As stated above, even 11.99 in that chassis with what you have is not possible. Not without killing something at least.

 

what would you recommend?

 

Turbocharge the car, at this point if that's what you're trying to achieve

 

I like how his sig now states "Soon to be boosted" after he figured out he could not achieve his time goal on an All Motor setup lmao

 

oh its possible to do all motor....just not with a honda motor in a 2,700lb car on pump gas lol

 

I've done it in an EG chasis. Consistant 11.7 @ 112 mph in a fully registered (street legal) cut to hell albeit, chasis.

This was with a simple B20 VTEC that I built. 12/1 comp, S2P1 cams, Rage replica header, and 91 octane.

This car was cut up to the point that it would be horribly unsafe on the street, but my customer drove it anyway. I will post a video in a few...

 

Will be waiting.

 

LOL!!!! win

 

Both of you are idiots. That's been my sig for over 1 1/2 years. I was going to boost my GSR before it took a dump.

nice. Like i said, why not aim high? If it does well, then it does.

 

That's a pretty heafty goal!!

I have a 273whp B20 in an eg civic with 3/4 interior (no back seats due to roll cage). It is fully registered and street legal and not cut to hell.

The best i've run with it so far is 12.2 (If i spend 4 grand on a tranny it will probably do 11.2.. but that's neither here nor there) lol... I'm sure there is more in it somewhere but man i'm about 600lbs shy of your chassis

I won;t bash you for trying but I don;t think it's possible at that weight with the potential of a B-Series

 

Not going to get it... very very very hard to see 11's with that chassis am b series. Boost it, k it, or h2b it.

 

It was a joke dude relax

 

And if it doesn't, you'll either be selling it since rebuilding wasn't part of the college budget, or going boost anyway.

Just because something can be attempted to be done, doesn't make it a good idea to do it.

 

wow well said

ps: have you checked for that intake yet! I have been waitin a few weeks
