2.1L turbo... :)
Someone handed me the idea that it would be bad to stroke a b18 then turbo...
i would bore to 84mm and stroke out to 95 mm... is that ok?
are there any downsides to stroking out the motor?

Re: 2.1L turbo... :) (Eresuncabron)
A stock stroke LS/VTEC or GSR makes too much torque to handle for a street car. My B16 makes too much torque to handle for a street car. Why stroke it and only compound that problem?

Re: 2.1L turbo... :) (FOrSfEd)
Not building a DD so i'm not to worried about driveability,and i doubt anyone can make too much torque... and i would get more HP too right?

You are going to be horsepower limited by the turbocharger, doesn't matter how big of a motor you're feeding air into. The stroker kit is just going to shift the powerband down a thousand or maybe more RPM's, in which case you might actually run out of gear before the end of the 1320.

You would make the same amount of horsepower, with more peak torque. EG: A GSR motor might make 500 HP @ 9000 RPM's and 340 TQ @ 6700. The stroker motor might make 500 HP @ 8000 RPM's and 400 TQ @ 5000 RPM's.
You have to decide what's best for your chassis setup. I would just save the money and run stock stroke.

Re: 2.1L turbo... :) (Eresuncabron)
go ahead and do it...you won't run out of gears in the 1320.
if you had peak torque at 5k rpm...it wouldn't matter unless your torque went straight down from there on. having a greater amount of torque on a drag car will also allow you to accelerate faster down the 1320...and if you do run out of gears which is almost impossible...run larger slicks or tires.
i honestly thinks it's a great idea...but i don't know how long your motor will last being stroked and making goobs of power. there's just too much tension on the crank and rods....but i'm sure it'll work out.
if i'm not mistaken...wasn't LISA KUBO's B16 bored and stroked as well??? i know it wasn't a 1.6L motor anymore!!

yea, keep it simple, you are only wasting money on a "stroker" kit which wont give you gains that other products could, which would cost the same as the stroker kit.
if you plan on getting your block sleeved, i wouldnt bore it more than 81mm, incase you might have some problems later on down the road. and would have to get it bored out more... than take it to 83,84, 85, 86mm.

Dart block: 1500+ dollars
Sleeves: 1000 dollars
Sleeves have been proven to work for 700+ horsepower at the wheels. Why spend the money for nothing by going to a dart block, unless you want tall deck.

Re: 2.1L turbo... :) (Eresuncabron)
i would go with a 84mm bore x 92mm stroke. keeps good r to s ratio on this motor. it would still be under square of course but your mid-range power production would great. good street motor

sleeves have their limits...while dart blocks are pretty much bullet proof. not only that...with sleeving the price will depend on brand/open/closed...etc.
but yes, both have pros and cons of their own.

Sounds like we have a dreamer on our hands here fella's..
Waste of bandwidth - but then again no one is asking me.

Re: (Drag_On)
WTF are you sayin.
come to my house next summer and the car will be built... probably with a dart block if they are as good as everyone says.

What class in Autocross do you plan to run with a bored/stroked/turbo honda? Is there a class you'll be competitive in with that, without spending gobs of money on suspension and LSD etc?
I haven't done much with the SCCA for a few years and I'm not sure what all the rules are for the street touring classes.
Unless you're trying to compete nationally I wouldn't build a car just for AutoX anyway.. IMO it's a lot of fun but not enough track time.

Oh jeebus.... STFU man !
I was 'dreaming' when I put together my built LSVT in my head... I was 'dreaming' when I built my turbo 4 door.... I was 'dreaming' when I spec'd out my n/a dohc workhorse. Guess what pumpkin ? Dreams come true.
The only waste of bandwidth in this thread was the part that was quoted at the top of my post.

Re: (X2BOARD)
thanx for the support man...
well i'm just trying to get ideas etc cuz i don't want to build something that totally ******* sux... so if any of you have more ideas... i'm definately listening
nobody has answered my question about a dart block yet... whats the deal?

What about sunken sleeves, or warped blocks. Having to machine so much off a sleeved block. There's a list of things, that add up to a sleeved block. Not to even begin mentioning the strength of the main girdle on the Dart block compared to a stocker being sleeved.
I's buy a dart if I was in the market.

Re: 2.1L turbo... :) (Nid Styles)
personally i would not want to build an insane turbo'd car for autox, if you are going to go turbo/autox car, i wouldnt look past a small turbo setup for quick spool....and about the dart block, if i had the money i know there would be one in my car right now
