I'll start with a little background:

About two weeks ago I started getting a little ticking coming from the engine. I decided to change the oil (it had been about a month since it was changed). After a couple days my ticking turned into a severe banging causing me to immediately pull the car off of the road.

After a trip to the Mitsu dealer I find out I have a spun bearing. So, instead of paying ridiculous amounts of money to go back to stock I am going 2.3l stroker.

I will be going with a Jackson Automotive Machine 2.3l shortblock.

My proposed setup is:

2.3l stroker
270i/270e cams
stock turbo @ 20psi
Walbro 255l/hr
AEM intake
3" TBE w/ highflow cat
Stock ECU flashed

- Will a 2.3l stroker make sense for a daily driver?
- I know i won't be making big numbers but will this set up be streetable for a daily?
- What are the pros/cons?
- Is there anyone running a similar setup that has input? Anyone run into problems?
- Any more feedback on JAM strokers?

I just spent about 3hrs alone searching on EvoM but it seems that most of the 2.3l are strictly racers or going for huge numbers. I just want a torque monster that is fun and reliable.

 

Stock turbo and 2.3L is pointless. That stock turbo spool fast as hell but will die out VERY quickly.

I recommend you upgrade the turbo if you're going to do the 2.3L.

 

ur top end will suffer a bit as the stock turbo will not be adequate enough. Atleast thas what I think.. could be wrong..

 

maybe a 20g migh be better? if ur not looking to spend the money for a gt30 or something.

 

I am familiar with the fact that the stocker will start blowing a lot of hot air after about 4k RPM I just want to be sure that I will not have knock or prematurely kill my stocker running at 20psi with the stroker.

Again, I am not looking for a ton of power but just want to make sure I am not going to pull a "knuckle-head" move by killing my new stroker with a bunch of hot air.

 

I've done just that, except with a slightly smaller turbo (standard evo4 turbo, 9T exhaust).

For daily driving its awesome, great spool up, lots of low-mid range torque.

The driving I do suits the low-mid range torque than high range torque so I find the thing great to drive.

Although I am wondering how a evo9-20G with the Ti exhaust will perform.

It all comes down to what type of driving you are going to be doing.

 

I think Buschur refered to the 20G and a stroker kit. I think he said it would work just fine?

Personally i'd go big like a 35R or somthing.

 

I have been seeing alot of post about evo's spinning bearing's! I wish there were upgraded oil pumps availiable.

 

I feel that is my car or close to it. I drive it 100 miles a day.
Not on the stocker(turbo) as said prior. I would at least put a 20g.

 

You can switch to a dry sump system if you have the time and money for it. <img>

 

I'm in the same boat except I already have a ams turbo kit still in the box. I would suggest a bigger turbo like everyone else,but now your talking a 10K build up !!

 

Agreed, what is with all these spun bearings?

 

It's all in the tune. If you're going to run a stock turbo on a 2.3, then you will simply have to let it taper off boost in the upper rpms. That will avoid overspinning the turbo and keep your EGTs down.

Did some digging and here is where you should be at:

Assuming a VE of 100 across the board: Holding 20 psi to a 7000 rpm redline, you would be off the TD05HR-16G6 compressor map at about 6500 rpm .. don't even think about 7000 rpm.

At 90% VE near 6500 rpm you would barely stay within the compressor map.

Probably the wisest thing to do is to let the boost taper off from about 20 psi at 5000 rpm to 16 psi by 6500 rpm.

Personally I would seriously consider getting a slightly larger turbo, such as the White Rabbit. People have run the WR on 2.3l blocks with excellent results.

That was exactly what I was looking for! Thanks for the input.

I will look into the White Rabbit some more but what about the 20G.

Will the surging with the 20G be bad with the 2.3?

Will I need to start looking at injectors bigger then stock?
