"I just want to make a tiny bit more power"...said every DSM owner before dumping 10k into a car worth 2k.

I found the issue. The adjustable cam gear bolts came loose, so the exhaust cam was sliding all around. Applied some locktite, re-torqued, now it runs great.

I can't see any visual issues with the springs and retainers - then again, I don't really know what a problem with those would look like.Would I only be able to detect a problem with the lifters if the cam lobe is all the way up? I don't yet have the socket to turn the cam gear, so I just...

Immediately following a pull today, my car started stumbling really bad and making some rather loud knocking noises. The knocking is not consistent, and doesn't follow a particular rhythm. I've been told one (or more) of the lifters may have failed. I pulled the valve cover off and wasn't able...

Thanks everyone for all the replies. Looking at all this, I do think the SD table being inflated at certain points is likely the cause for the airflow inflation. Doing some quick math to back out that inflation, looks like I'm actually closer to 55lbs/min, as bastard DSM originally guessed...

Interesting. Well, I did do some of my fuel tuning in the config settings, so maybe that's causing discrepancy?Low to mid 50's sounds more reasonable - do you have any math or logic behind that?

Couldn't find any solid info on this, but I've heard the airflow measurement in ECMLink isn't accurate if you're running speed density. Well, I'm running SD, and my log (attached) says I'm flowing 67lbs/min at 25psi on my 6-blade hx40 on the .70 a/r housing. I'm just starting to break in my 9:1...

I've had this problem before. Turned out to be a slit in a vacuum line. As the car heated up, the inside of the slit in the rubber hose would sort of melt and fuse together (it was close to the manifold), and seal air properly after it cooled down. But when the boost pressure eventually reopened...

My advice would be to stick with your evo 3. In my opinion, far more downsides than upsides to running a tubular manifold for most people. They run hot, crack, and most require significant rework to the downpipe (which can cause other issues).My preference is to run a ported 2g or evo3 on my...

I've had it with cheap tubular manifolds cracking, so I bought this one from MAP:I'm trying to get it on this week - spacing is a bit tight with the hx40, so we'll see.

I just recently got a new long-block 9:1 2.3 stroker and a JMF SM IM. Turbo, injectors, ignition setup all the same as with my last setup/tune on my stock 2.0 w/ stock IM. I basically kept the tune the same, as I figured that'd be enough to just get the car drivable.At cold start, car idles...

Yeah, that'd be helpful. Thanks.

How much boost? (and did you mean 6psi more, or 6 degrees more)?

I'm going from a stock compression 2.0L to a 2.3L .30 over 9:1. I'm curious how I can expect my peak timing to change.I've searched around a bit, but haven't been able to find consistent info.For example, if I was running 35psi (50/50 e85/91) from an hx40 on my 7.8:1 2.0 with 17* peak...

Probably a super silly question - any chance this ECU is reflashed, and is currently in valet mode?

OP, can you provide a bit more info on what happens when "it goes all retarded" after 4k? What's it sound like? Is it always exactly 4k? How does the car behave? Is is shaking, stuttering, misfiring? Will it continue to rev to 7k? Do you hear any detonation?

The block deck appears to still be true, so I'm going to forego any machine work on that. I did use this opportunity to get a new, ported head with new valves and new springs. I also did a ton of reading over the past few days on composite vs MLS, APRs, L19s, A-1s, etc. Decided to go with a...

If you're in socal, I'd recommend BBR Tuning (https://www.facebook.com/BBRTuned). He's local, and one of the best when it comes to DSMs and Evos (also a super nice guy).

Yeah, I was thinking about that. Unfortunately, this is actually a DD right now, and all the decent machine shops in the area are on 1-2 month waits. I really don't want the car to be in the shop another 2 months if at all possible.Right up until the very second the head cracked, the engine...

The discolored area in the middle of the cylinders is where the crack is. HG was totally melted in that area.

Got the head off today. The head itself cracked between cylinders 2&3. the HG must have gone bad in that area, then the metal eventually wore out from the heat. Have a new head, springs, valves, etc on the way. With any luck she'll be up and running end of next week.Thanks again for all the...

Thanks so much to everyone for all the help - the dsm community is one of the best benefits to owning one of these things.Are you referring to the compression ratio? If so, it's basically a stock 1g long block, so should be 7.8:1. Thanks for the heads up on the "washer bite."It was so...

Interesting...Sounds like that could be my best case scenario. I should find out today or tomorrow, hopefully. If it is the HG, and if it did blow from excessive compression, what's the best way to avoid that in the future?

So, did a leakdown test. 155 in cylinders 1 and 4, ~50 in 2 and 3. Time for a tear down. I am curious to find out what happened.

Thanks for the replies. I no longer have a garage, so I'll have to take it somewhere for a leakdown test.

I've been running an evo 8 ecu in my 2g for probably 5 years now, and it has been a great experience for me. Although I've never run ecmlink, I've heard from others that there are still some nice things you can do in ecuflash on an evo 8 ecu that you can't do with ecmlink. A few examples include...

Went to the dyno shop yesterday. I went up to 7k on the first run, and it seemed to be still making power, so went up to 7,500 on the second run. As soon as I passed 7k, the power dropped off immediately, so I didn't take it any further. Here's a video of the pull:On a MAHA LPS3000 Chassis...

Many thanks to everyone for the replies - this is all very helpful. Sounds like it's time for me to start reading up on spring options.@UrbanSmoker - how long were you running an HX40 @ 38psi on stock springs for?@jakelandry - The bottom end has about 15k on it, so there (hopefully)...

@bastarddsm - to me, subjecting a stock bottom end to 600whp is a bit more crazy than running stock springs on my setup. But, if it does grenade before I can put some springs in, that gives me an excuse to finally build the motor :)

I have a stock bottom end - I don't want to make 600+whp right now.

Yeah, I've actually only been going to 7k on the road. I'll probably go up to 7k the first few pulls, and if I'm within a few hp/tq of some nice round number, go to 7.5k on the last pull.

Springs are certainly next on my list, and I do plan on getting something a bit more high-end. I just haven't gotten around to them yet. I've never dyno'd the car with this turbo setup, and the opportunity just came up, so I'm curious to see what it puts out as it stands now.Maybe I'll just...

Sorry about that - info added to first post. Brian Crower 272/272s, stock valve springs, 1G head.

I have an evo8 ecu in my car, and have helped a few other people with with evo ecus set up some base maps. PM me your email, and I'll send over something that may work well.

When the evodroid is turned on, it automatically launches evoscan, connects itself to the OBD-II port and starts logging/displaying data. The tablet does need to be powered on and off manually, but that doesn't bother me too much. What does bother me, however, is that you can't keep the USB from...

Don't get me wrong, the whole "PC connected to a screen" is cool, I just think it's more than most people need. Once my tune is dialed in, it's dialed in. I'm not upgrading parts on my car often enough to make tuning something I need to do more than once or twice a year.So, unless you want...

Welcome to the DSM world, and congrats on your car. One of the things that makes owning a DSM so fun is the incredible wealth of knowledge and experience amongst the community. Tech articles (including proven upgrade paths) can be found easily through the search feature, but it looks like you're...

For now it's just real-time display.Other than putting the tablet inside the vent area (which I covered in this thread), this tablet is a plug and play unit as Bud92gsx suggested. Click on the evodroid link in my first post, and you can buy one yourself.You shouldn't need an evo8 ecu in...

Yeah, I got pretty close to doing something similar to yours. I really, really didn't want to lose my vents, but with the HVAC piping behind the tablet blocked off, I don't really lose any of the air movement. I was also looking for a place to put it where I could still read all the data, even...

That looks awesome! I was thinking of doing that too (I actually already have a screen in my DIN as well), but I wanted something that was a little higher up on the console. That looks very nice though. Nicely done.

I don't think you can flash from this tablet. It has a built-in version of evoscan, which is essentially just a logging program with some cool visualizations. I use ecuflash to flash the ecu (via my laptop). It does actually record logs though, so I can actually tune with it. And yes, it is real...

I think it's your connection. Links work for me.

When I put an evo 8 ecu in my car, I quickly grew fond of evoscan's data visualizations. It was my goal to eventually put a monitor in my car that could display real-time data, but something that had a factory look. About a year ago when Limitless put out a pre-order for their EvoDroid, I jumped...

I'd try a 50/50 blend of E85/pump. I run that now, and am very happy. Bring a few 5 gallon gas cans with you, and you'll probably only need to make the trip once every few weeks.

Oh really? Wow, that's not good. I think these are the ones I bought (although I bought them a few years ago, so I'm not entirely certain). They were around $100 if I remember correctly.

To the extent possible, I'm trying to maintain a stock look, so I didn't want to have a black hood on a white car. The hood definitely looks better in person than I thought - very happy with it so far. Those projector headlights are all over ebay for around $100. Here is one example.
