Rebuilding motor, need suggestions

[EVOJ]

2.3 Stroker... Many have done a 2.4 with disastrous results. I'm in the same boat as you paying for an Evo only my motor went BOOM. Currently undergoing a 2.3 stroker with a FP Black E85

Well thing is car runs fine normal under wot it gets 2/3 counts of knock and now started last night if i go wot it will start popping and cutting. My wideband just took a crap (only reads 20.0) and will occasionally go to 10.0 than right back to 20 stupid glowshift pos.

Will do leakdown this weekend.

Check your spark plugs and maybe just get a replacement set to go in after your leakdown test. You told me you over-revved, hitting the limiter can cause massive amounts of knock and cylinder pressure damaging a spark plug electrode (happened to me once).

Really? does this just apply to evo's?
I've never heard this before.

I have some widebands available, I'll send a PM now.

Yeah, not sure where you're getting this info from. I built a 2.4 for my Evo with no problems at all except getting the wrong freeze plugs initially. I would've preferred to do a 2.3 but MAP did the machine work for me and didn't like the deck surface, so I started fresh and 2.4 blocks are much cheaper than Evo blocks.

Personally, I wouldn't do anything to the cylinder head except the lightest port cleanup, the factory valves, springs and retainers are plenty good for what you're talking about. That's unnecessary spending doing anything to such a good factory head.

Thought of doing a 2.4 but heard stories on how it went really bad. For a seasoned vet such as yourself yeah it could work out.

Talked with Kyle at MAP yesterday and he said he absolutely loves the 2.4s not an issue at all with them. Everything you read at times has to be taken with a grain of salt

I prefer the 2.3l on the Evos, I have had plenty of basket case 2.4l Evos in here for tuning.

I know when Andrew and I were researching how to build his IX we decided the 2.3L was the better route to take, especially for the IX w/MIVEC. Retaining the stock block really simplifies things.
