Well, if you have not already been here: http://theoldone.com/forum/topic.asp...long,short,rod
there is a lot of information... the focus is mostly Hondas, but the information is sound.

Of course not just this one post... there is a wealth of information here.

 

I voted blueprint. Mitsubishi is known for their great engineering, right? So why would you change the displacement of the engine that the engineers obviously thought was best? If you want over 2.0 liters of displacement why didn't you buy an STi?

 

So im guessing you were the one i was bidding agianst on ebay for the short block huh. Well at least i won the cylinder head . LOL good luck on the build! If you want to rev high there is no question BLUE PRINT AND BALANCE the 2.0 is the only way. There have been claims the strokers can do it but no evidence yet. Boost Solutions is supposed to be raising there's to 8500 this week to see how things work. THey claim a 10K redline.

It depends on how much money you have to spend on it but RPMs ARE a replacement for displacement. If you put the same effort and funding into the 2.0 and 2.3, the 2.0 will make more power but it won't be over a broad range. Are you going to race it or piddle around town? If you are racing I would go with a 2.0. If you want something on the street to go see Grandma (in a hurry) I would go with the 2.3. But if you are going to invest the extra money needed to make a stroker rev the same as the built 2.0, then the answer is obvious. But that is $$$$. Good luck.

 

Jack,

Talk to Dave Buschur about his thoughts on strokers.

Speedlimit..

 

Theres a 500whp Evo around where I live and I think his engine has been blueprinted. That car revs like a ****, and sounds like an F1 car! Sounds like an interesting route to take, but you'd lose torque by going for the higher redline, correct?

 

He'd still have more torque than he has now. Redline is not a function of a lack of torque, but low displacement is. He has a 2.0 right now so he is not going to be losing any.

 

LOL yeah, that was me, Sorry Chris.. It was the last major component that was missing.. and it was a price I couldn't pass up.

I do agree with you on the B&B route, but I'm taking a wait and see approach for the time being (hence the reason I posted this) If I can see these strokers put the power down, and hold up, then its a no brainer.. But I'm torn simply because of the proven engineering, -vs- the additional displacement. I'm all about the street and reliability so My approach has been somewhat different than most. I've been fortunate that i"ve good gains with what little I've done so far. But mostly its been my careful analysis of the products on the market and matching them. This is just another "Step" in the route..

 

Jack, it depends what you want your car to be in the end. You are in the point where you have to make up your mind, do you want drag car? Or you want a track, street monster? I am not much of drag fan, as I believe our EVOs are not made for drag racing however I would take it once a while for fun. I would go with 2.3 or 2.2 stroker kit either from AMS or Jun. I am sure you will be able to rev up to 8000 RPM and on top of all that you are going to gain nice amount of torque on the low RPM which we all love. You stock turbo wont be any good for both applications anymore, as you will be leaving so much power on the table. Stock turbo might surge with the 2.3 and the power band will fall after 8000 RPM for sure. Your cams are so generic 272 you will need to go with Tomi or Piper custom made for your application. I know that the cost is important for you and all of us but when you go in that deep don’t try to save because it will come back and bite you in the A S S. In the end I would go with 2.3 and 3037 or 3071 turbo for the ultimate spool and top end.

 

I hear ya... My turbo isn't stock, its based on the JDM Evo turbo though.. But yes, I'm not interested in drag racing. Mostly driving on the track and street. So anything over 8000rpm isn't my goal. For the time being I want to stick with the twin scroll design simply to prove that the power is there to be made. Ultimately I may switch to something else.

I am going to work with the 272's for the time being, however I am likely going to work with a company (to be named later) on a custom grind.

I'm actually not trying to save money by using these parts, but that their cost effective, and somewhat matched to the amount of airflow I'm intending to move through the engine.

 

what kind of power output are you looking into?

 

I'm more interested in torque than horsepower.. But I'm not looking for a large amount of horsepower that peaks at an RPM range that I rarely use.. I'd much rather go with the lower number and get the greater torque at low RPM's.. I don't really want to put a "Number" on what I'm looking to get, since its always a disappointment when you do that.

 

then you need 2.3

 

Malibujack,

It it were me, I would stick with a built 2.0L for sure. I'm a track junkie and my track car (a BMW E30) has an 8000 rpm rev limit. When I take the Evo out on the track, I really miss that extra headroom. It lets you accelerate all the way through the corner without having to upset the chassis by either shifting early or backing off the throttle to avoid the rev limiter. Besides, on the track you're rarely ever below 3-4000 rpm anyway, so turbo lag is not an issue.

But it sounds like you're looking for a street car that will see some time on the dragstrip. In that case, improved low-end torque and faster turbo spool would definately be appreciated more than an extra 1000 rpm at the top of the rev range.

I guess I really am a street racer at heart.. LOL
