Hey guys new to the site and hondas but not horsepower.

So I know this will be kinda weird from a new member but me and my brother are making another street/strip car and we want it to be a turbo'd civic hb.

We already have a 500+hp 72 chevelle and a 74 comet gt with 500hp.
But we now want a 500+ hp civic and we are not sure where to start or what the best platform is.
I know we are gonna end up with a 72mm or bigger turbo with most likely a
b18 block.
Not sure on the tranny yet.
So I guess im looking for some advice from the guys with big hp hondas.

Thanks guys

 

72mm turbo is pretty damn big for 500...unless the "+" was meant for around 700-800 and more. There's a lot of builds on here around those hp goals running a lot smaller turbos. I'm shooting for 500-550whp in the next couple weeks, and I'm running an LS/VTEC setup built/sleeved 10.8:1 compression, Precision 6165, 700 hp treadstone core intercooler, and so on...My turbo is probably even good for 600whp. Any specific build questions?

 

You do realize that 500whp from a Civic is a LOT different than 500whp from an old Chevy, right? Less weight, different chassis, completely different weight distribution.

Do you want the best platform, or the least expensive platform? You can make 500 with a K, J, or C swap all day long without thinking about it. A B is going to take more work and more money, but is still doable.

 

Well the best platform is obviously the K motor, the technology employed on the K series is far beyond that of the older B series motor. What will be cheaper, and easier to do? The B series, obviously, you wont have issues with fitment, parts will be cheaper, and the aftermarket will be larger.

The first step to all of this is getting your B series block sleeved for that kind of power.

 

I was aware that the block will have to be sleeved, now what kind of rods/pistons are you running?
I'm kinda just looking to see what your guys setups were and to make this power and at what psi.
Did you upgrade your cams too?
And yes the 72mm was to give me room to grow later down the road.
Yes I was aware that they are two completely different platforms for power.
We just wanted to do something a little different and I think we are going with a b18c block since there's not many k series motors around here.

Yes that's kinda why we are leaning towards the b series to do this.
The block will be sleeved forsure

 

whats the budget?

 

itr/ctr cams would work, skunk 2 tuner 1s or pro 1s would likely do better, depending on how large a turbo you run.

and 500hp with a 72mm turbo doesn't make a lot of sense. you can make 5-650 all day on a smaller turbo like a gt35r, or 5858, or 6262 if you want some room to grow. Putting a 72mm turbo on a car thats only built for 500 hp is going to give you spool at like 6k rpm, and a 3k powerband. I'd strongly recommend looking at a more "modest" turbo.

You can run eagle rods and save some coin, but if you decide to run a 72mm, you'll likely want manley tt or pauter rods.

good luck!

 

Around 10k as of right now.
Thank you for the advice, I will have a look at a more "modest" turbo since we dont want a ton of lag.

 

I'm making 460 @ 14psi. Could easily make more and lag is negligible.

WRONG!!! The Fastest out there like, palo,miller,speedfactory are all BBBBBBBBB. On the other hand if he was looking for an all motor set-up than yes k will be the one. Until then B is cheaper and is holding a Record of 8.3@180+. Enlighten me if i'am wrong

p.s

500hp is constantly done by many on stock sleeves.

 

Just because it has been done, doesn't mean that it is done RELIABLY (ie for DD duty).

Lots of stock sleeves have failed well under 500 whp. Bottom line is, it is a gamble at best. Personally I'd sleeve anything over 450, and I'd still consider it at anything above 375-400.

Hell, you could build a motor on stock sleeves that will make 800 whp for three dyno pulls. Yeah, stock sleeves made 800 wheel, but it lasted for 15 minutes.

Just my opinion. If I were op (and I am building a 500whp SLEEVED dd build right now), I'd sleeve it. Better safe than sorry.

 

Just my 2 cents, but isn't that fairly high compression for a boosted set up?

 

No not with todays tuning.

OP yes Id recommend you go with something smaller than a 72mm turbo, you said you would like room to grow, but how much room do you want? Whats the max hp you plan on making?

 

Check this link out, these charts will give you a rough idea of some parts combos you can run to achieve various power levels.

I have had alot different setups from 300-800+ whp and I have the most fun with a GT35r. The spool is good and you have plenty of room to turn it up down the road. It gets tough to hook over 600whp on the street anyway.

Good luck

 

Thanks guys you are all giving great info for my build.

Now what are you guys doing to the trannies to hold this power?
Anything special like beefing up the syncros?

 

I would like to sit at around 650hp

 

crazy thing, the only thing you really need is a LSD
MFactory
OEM ITR
Quaife
Wavetrac

the stock tranny is pretty freaking strong, the LSD will help with traction and take off

 

Wow did not know that.
Kinda crazy it will handle that type of power

 

There are many 9-10 second Hondas that have a stock transmission

From my experience the Honda transmission can take a lot of abuse and still love you

 

Actually the stock LSD can't "handle" 650hp. Unless the wheels are turned the Torsen stock isn't really made do do that. Either way. what takes a mustang 650hp only takes a Civic about 450 to do the same things.

The car starts to just rev and lose traction at 1:28 in the video.. just like your will.

But the car is nicely built.

 

That car is pretty badass forsure.
I'll make sure I don't cut any corners, I would like this car to hook up half decent on dr's

 

I'm running CTR cams and eagle rods with Arias pistons. I think 10.8:1 is a good compression. Not too high yet it will still help with midrange pickup. With E85 and good tuning there shouldn't be any issues.

 

Unfortunately I don't have any access to E85 here in Canada lol.
I can only get 94 pump gas and the occasional c12 race fuel.

 

9.5:1-10.0:1 is fine for 94 octane for lower boost pressure levels (even on smaller turbochargers), and C12 is just fine for the higher ones. What are you guys at per litre now for 94 octane? $1.37

 

I would use pump or race fuel
Don't hop on the e85 bandwagon
