Fist things first is it a 6 bolt what you want to build up?

If it is, I would say go with the 2.3 stroker engine.

 

For the $ and reliability down the road I wouldnt do anything but a 2.0 6-bolt. For 99.9% of DSMrs a a stroker is overkill.

 

Well, I have had 2.0, 2.3 and now a 2.4. The torque for a street car and the extra air flow are super on my car. The 35R I have seems like a small turbo, spools like an 16G/18G. Roll into it at 2300 rpm and hold on. Pulls hard until I let off. I have to say it is a real joy to drive.

As for the blocks, I have always built a 6 bolt. However, I really like the main girdle of the 7 bolts.

 

You have to ask yourself, what are your priorities. There's fuel economy, low end, top end, driveability, throttle response, emissions, durability, ect ect. If you sort it out, you'll answer your own question.

 

Well guys, both blocks i have are 6 bolts, and i think it is slowboyracing.com that has a girdle for the 6 bolts that are like the 7 bolts. I was kinda leaning to the 2.2 stroker. Magnus has a kit for about 3k for pistons, rods, and crank. From talking to other DSMers here in south miami, the 2.2 gives you the best of the 2.3 and 2.4 stroker, more torque for the low end, and more airflow for the top end. Has anyone ever built the 2.2? Pros and Cons? Thanx for the feedback.

 

Go 2.0, I've heard of longevity issues with the strokers, also, unless you're planning for more than 550 hp, I would leave the stock bottom end in. There are plenty of other places in the motor where you can spend the money saved.

 

Yeah there is alot of diffrent factors to ask your self in what you want in a car. No one can tell you the best motor cause everyone has diffrent thoughts about 2.0 and strokers/destroked.

 

yea, im shooting for somewhere in the mid 700hp, but no less than 650hp to the wheels. What are the longevity issues with the strokers?

 

Do some research. This has all been covered 1000 times

 

A 2.2 destroker is awsome because you get .2 extra displacement but can still rev to +9k rpm.... Or so ive heard.

Honestly if you like the down low torque, and like to kill stock drive train parts faster, id definitly go 2.4 and slap a big but hard hitting turbo on that thing and go lay down 600 something wheel with race gas and excellent tuning while still being able to get full spool by 4500 while reving the 2.4 out to 7700-8000rpms....

 

Yeah ive been looking into one of them there destroker motors, but everyone is like ooo its soooo top secret. Anyone have any info on it? Id like some more displacement and still have top end power.

 

700 is a tall order to build, most people would crap themselves if they rode/drove anything over 400. Longevity issues occur in the strokers because of the rod to stroke ratio(I believe that's what it's called). What happens is the rod is at such an angle because of the larger circle made by the crank, and the skirts of the piston push on the cylinder walls, or something like that. I still stand by my opinion though. Like I said earlier, 700 is a tal order, but it can definitely be done. You'd need an EMS of some sort ofcourse, 1600cc injectors, a bosch 044 fuel pump, bigger fuel lines, a twin disc clutch(if 5-speed), hella-big cams, probably aluminum rods to rev it out. The list goes on and on. See if you can ride in someone's high horsepower car, and see if you really think you can handle it, or if you really want to go through all the expense. If you still decide to go through with it, make friends with your local speed shop, you'll be one of their top customers. I think it's Titan Motorsports that's down there in Fl, they could probably help you out, and expect to pay, they're high dollar guys.

 

I'm putting together a 2.4 since I want to have a retarded street car, but honestly, I would go high compression 2.0 if I cared about making the most power possible and tearing it up on a dragstrip.

I had a 9:1 2L in my galant for quite a while, and while it's certainly no 2.3 or 2.4 in the torque department it's vastly better than the stock 7.8 or even 8.5:1 stuff- and it will help spool a big turbo a bit sooner.

If you have E85 nearby and can run that or racegas all the time, I'd even consider going 10:1

 

HOLY S***!! 10:1 comp on our turbo motors? Could we really do that? I thought thats why honda people can only boost like 7lbs on stock motors.

 

Well thanx for the info guys, $ isn't an issue, thanx to an understanding wife, and im s.w.a.t medic .
I think im gonna go the 2.2 route, but keep the 2.0 turbo block around, just incase the 2.2 doesn't work out. Ive had DSM's for a while and the motto is: "If it aint broke, its just a matter of time."; But I love my DSM's and will never let them go!

 

Also if anyone has any experience with the 2.2, or any other destroker, please let me know, your info is really apprecieated

 

4g64 block with a 4g63 crank is the best combo IMO. The piston speed is fine and the engine will be under square for use with larger turbos(more stability in the rotating assembly for higher rpms). I didnt know SBR sold the 6 bolt girdle. I would get that if you build a 6 bolt. I'm assuming your going to have a built tranny. Trannys DONT like high rpms. Remember basic physics in college? Velocity is much more useful for transferring kinetic energy than mass. So if you dont have the 3k necessary for the tranny then I would just build a stroker anyways.

Good luck... And go 9:1 compression or something
because you do have a e85 pump in Miami

 

I am building a 2.2L stroker motor now. Can't tell you much right now though, as it is still in pieces. Should have it all together soon though.
Good luck with the build I had problems with pistons at first.

 

hey guys, i know some will be interested in the 6 bolt girddle that also comes stock on the 7 bolt, this is a must for an engine build. It was magnus and not SBR like I originally said. Any new info on strokers?

So how is your build coming along.What did you decied?

 

Bradikus: The reason honda's are so limited on boost has more to do with heat issues than actual cylinder pressure issues. They melt piston rings too fast. My friends integra runs 10 psi but he has enough fuel to keep the egt's down.

As far as which motor to build. If money were no object I'd build a 10:1 compression 2.4 motor with EXTENSIVE head work done. Needless to say the low end and spool up response time would be amazing. But that's just me.

It also has to do with them being an open deck and having weak rod bolts.

I had to make the same choice, and well the fastest dsm's are rocking the 2.0l. Not that it matters now

Im still debating, ive spent most of the my time taking care of the chassis, paint, minor cosmitics. Im leaning towards a 2.3 instead of the 2.2, i would do a 2.0, however i want more torque for my AWD. Any suggestions?

 

IMO go with the 2.3L. Buy the Eagle rotating stroker assembly and your good for 900+hp. You'll have great torque and spool for the street. You'll love it.
