Its coming along awesome man. Keep up the good work! :thumb: if I was gonna suggest to get something, I would suggest an aluminum radiator to keep temps down along with some slim fans. With everything you have done, its gonna get a little hot under your hood!
 
Looking forward to see you get into this journal. Thought I would weigh in on you with your ???s.

A 272 or something slightly less aggressive (like 264s) will get you there, I would go with HKS 272s but that's personal preference.

I'de not recommend the adjustable cam gears, they won't make any difference with the upgrades and power level that you're looking for. Save your money for better things.

The water or meth injection is really deceptive; you're right in thinking that it is NOT like nitrous oxide. Water or meth injection is an octane booster. Since the system would be activated by a pressure switch or your DSMlink, you're also right that it wouldn't always be spitting water or meth into the intake. The concept is simple, if you want to be aggressive with timing and boost, you're going to run into engine knock with pump gas. One solution for an aggressive tune is to run a higher octane fuel (e85, C16, meth, etc) which is more resistant to knock. The other is water/meth injection which will effectively raise the octane level of your cylinder on demand. If you go this route, you can deactivate the system when you're driving the car on low boost/conservative tune and activate it when you're running high boost/aggressive tune. It's worth mentioning, in your case, that all of this can be actuated by DSMlink.

Just my .02 cents.
 
Thanks for the support! I am most likely going to be picking up a water/meth injection kit. Also still deciding on if I want/need cams.
 
Awesome I'll subscribe!

Also I finally got all my parts in. When college is out 2more weeks :) I will have free time to get this thing going!
 
i say get rid of evo3 and upgrade 20g or 50 trim. Will make it easier to reach 400hp.
 
Lol probably but the Evo 3 is a very nice street turbo. if I can't hit 400 I'll be happy getting close to it. Besides this is my first dsm build. If the time comes that I need to rebuild entire motor I'll look into going with a bigger turbo
 
Well yesterday I towed my car over to my dads. College ends tomorrow and I'll be starting on it this weekend. I have decided to just pull the motor and tranny all at once. I think it will make it easier for changing the clutch and the head. I'm excited to get started on it, so close!
 
I would HIGHLY RECOMMEND building the trans first while it is out Been there and broke the stock one twice at only 400whp. It blows. "Once and done" is my new motto. I highly recommend you do the clutch line now with the new clutch going in, it is very cheap only $15 on ebay. Good luck.
 
Started working on the tear down on Saturday and had some errands to do Sunday. I got back to it today, Monday, and the motor is out! :hellyeah:

So tomorrow I will get the head off and get it to the machine shop:thumb:

Decided to do an A/C delete as it is not working anyways and would need to be recharged.

Also will need to get new seals for the tranny. I have not decided if I should get it rebuild or not. I don't have the money to send it in to shepTrans. Suggestions on that would be nice.

Here is some pictures of what I have done so far.

**EDIT Pictures have been lost to time. Updated and will re-Post pictures.**

Good to see you starting! Looking forward to seeing more... your goals are very similar to mine.
 
Looks like a good build. Your going to have a hard time reaching 400whp with an EVOIII turbo though. I have almost the same setup as you and I made 353whp at 28psi (also my turbo was ported by FP). My tranny just shit the bed after the tune though so its going in for a rebuild at the end of the week :ohdamn:. I will tell you that 353whp is a lot of fun though :thumb:. You could very well reach your goal or come very close with meth injection if you decide to go through with it. Good luck on your build.

P.S. Depending on how many miles you have, you might want to consider changing the rear main seal while the tranny is out if you have not already. It would suck for it to start leaking shortly after getting it back up and running.
 
Got everything off the block today and head is off. The head gasket was just barely torn in 2 places but just enough to make it leak. Yah I was planning on replacing all the accessible seals for the tranny, axles and T-Case.

Anyone know a good degreaser I can use on my engine and inside of engine bay? I want to clean it all up and make it look clean. There is nasty oil everywhere LOL.

Here are some pictures.

A bunch of cans of carborator cleaner will get anything noticeable off the block itself, and a pack of hand towels. Just harness it above a good sized pale to let it all seep off into it when cleaning, re use what you can too. Build is looking mighty nice though, we also share similar goals
 
Looks good cant wait to see your progress I have similair goals and its nice to just get your hands dirty
 
Got my crash bar cut and ready for the FMIC. New headgasket on with ARP head studs on, changed out the fuel pump for Walbro 255, cleaned up some bad connections in the engine bay. Motor is all assembled, just waiting for seals for the tranny. Then will get start to put it all back in. LOL

Forgot to mention. I had the oil port mod 1 done to my head while it was at the machine stop. Didn't get a picture of it but it was done really nicely.

Nice build, But a quick question. How are you holding the car up that high? All I see in the photos is a tire on the driver's side and what appears to be a block on the passenger's side? ......:nono: LOL :thumb: .........keep up the great work!
 
LOL yah there is a block on each side and then jackstands on each side, it is sturdy. I would not crawl in that if it wasn't LOL
 
Awesome, I am thinking of picking up my first DSM sometime during the summer with a similar goal. I will be watching this thread. Do you think you will need to rebuild your tranny?
 
I do not think it needs a rebuild. I did replace all the seals that did not require taking the tranny apart. If I end up needing a rebuild I will save for a Shepard stage 2 tranny :)

Getting closer to finishing. Motor is in.

Good stuff, any reason you chose to pull the motor? Or you just did it to make it easier to work on everything?
