That's correct, the XZ case will not work with a .21 sleeve.

As jpalessi mentioned earlier, the JX case can be used with the V-spec internals. So if I were to have a problem with a cracked V-spec case, that would be the first thing I'd do.

LOL I wouldn't panic just yet. I still think that there are far more V-specs out there without these issues than there are with. That's not to minimize the problems that the people here have stated, but the V-spec is probably the most popular engine out there and has been for years. There's bound to be some failures/issues in production.

I agree! Even though I got punked. I know allot of people who run them with no issues at all, and they all love them. There are lemon engines with every brand. I just buy now from the companies who admit its a Lemon and send me a new one

Ya no need to panic. I have 4-5 gallons on my v-spec without changing anything and it runs awesome. It doesn't have too much pinch anyomore but I still see it lasting several gallons more. It is one of the best I have owned. First turbo motor I have had and I'm really liking it. Still running the stock plug that it came with. That would be impossible with a standard plug. Instant power from top to bottom and absolutely ZERO tuning problems with runtimes in the 10 minute range. Definately a winner in my book. I just bought a brand new speed from cjm1126 for next outdoor season.

Oh yeah if you are looking for a speed cjm1126 is the person to talk to. Very reasonable pricing and super fast shipping. Very knolagable guy.

After some hassle with hobby services they took care of me and gave me a new case. Thing was the old case the crack you could barely see. I could kind of see it but barely had a little ledge which I could scratch with an exacto knife. But when I opened up the backplate and pulled the crank... Oh boy you could see it then, probably 3/4" or so. Check for this good. Good luck
wow they actually gave you the time of day! Ive had the cases crack on 2 different V-Specs in 2 different cars. Sent Hobby Services my case and they sent me a bill for $90. I wrote them a letter explaining the situation and that im not the only one this has happened to at our track. They sent me another bill and said its not under warranty and that it could of been caused by 10 different things. Told them they can keep it and if they can throw it away for me. They have a problem not the consumer.

Thats the easier motor in the world to tune.... OS has the best carbs, the longest needle which makes them cake to tune. I think you've been messing with the jet (Some refer to it as the middle needle) If thats been messed with then your on your own. Set it to stock and silicone over it so you or your novice pit guy dont turn it thinking its the low end

Also 99% of the time run a OS P3 plug only
Yesterday was The first time since i got the motor back in febuary that ive messed with the middle needle, i was at my wits end after trying everything else possible tuning wise and that was the only thing left to try, it actually improved the tune abit.

These are the symptoms of the engine:

Ill return the needles back to factory settings via the manual
The engine will start and barely run/move forward at full throttle because of rich settings.
Start leaning out top to get some rpm's into the engine, just enough so it clears out right at full full throttle.
Then ill start tuning the LSN, no matter what i do to the lsn, it will not improve(THIS IS ALL BEFORE I TOUCHED THE MID NEEDLE), even after screwing the lsn almost all of the way in, it is completely rich down low(gluggery and a heap of smoke) and as soon as i get off the throttle for 3secs+ the engine will flood with fuel and ether die or i will have to pump the throttle a few times to get rpms into the engine.

Thats what's happening, any ideas are greatly appreciated.

I would try a new OS p3 plug, and make sure your glow ignitor is fully charged. Sounds to me like a weak glow.. Our Glow Plugs will only carry the glow from the original spark from your ignitor. So a weak ignitor = a weak glow. Most ppl believe that as long as it starts, it's all good, and that's just not the case. The glow WILL NOT get better during combustion. Good Luck!
