Motor work?
Hey guys Im about to do some updrades on my 03 Evo and I have some questions. I know that people will see this thread as pointless but there are reasons for me asking.
My current set-up
I am ready to pull more power out of my Evo and I have decided to add the following parts........Red turbo, HKS EVC 6, race gas tune, and Megan o2 housing. Now my car has about 72,xxx miles on it and with those miles and the hell im going to but it through on the new setup Im wondering should I do some internal work? I have looked into pistons, rods, valve springs and retainers, and bearings. I have head studs but they have never been installed and I have read thread after thread on people saying you should have them and people saying not to. I also would like to know if I should port the exhaust manifold, do anything to the throttle body and the intake manifold.
My current set-up
- 9 turbo
- Intake w/ LICP & UICP
- Perrin TBE
- HKS 272s
- Walbro 255
- Hallman MBC
- BOV
- 880s
- BR Race FMIC
- Ported and Coated o2 housing
- Exedy Twin-Plate Clutch
- Jestr Tune

preferably yes.... 4g63 is bullet proof , but sometimes it can only hack so much
you should be straight with your new set up for a few months ...
sooner or later its gonna go BOOOM! jus piece together a rebuild kit when you can and when its complete well do a rebuild

You should stick to pump gas maps only once you get a race gas map you have to keep on going in to upload the pump gas map and that is a pain and over time could harm things.
Building a block is not cheap even if you have the skills and times to do the job yourself. Good luck on getting a red anytime soon.

- Rods - no, unless you're going with new pistons
- Valve train - no, unless you're going with a bigger cam, or want to rev higher (not a great idea on stock pistons and rods)
- Head studs - yes
- port the exhaust manifold - sure, why not.
- TB and intake manifold - send it out to have it ported by wilson (through Buschur) and up to a 65mm TB

Yes he is and no I dont think he needs to build the drivetrain.
Nick, Depends on what your looking for, want a great spooling turbo like a green/red or something a little step up to a 35r?
If you have the extra cash around, with your milage it wouldnt be a bad idea to just go ahead and do some bottom end internals.

Thanks for everyones input....I am still currently on the stock transmisson and transfer case. I looked into Shephard doing some tranny work for because I know sooner or later this will be a issue. As we all know the 03's are known for having the worse problems with the TC. This is why I try to stay far far away from launching my Evo. I know some people may think building the motor right now is uncalled for but I think its needed. I dont DD my Evo and I have taken it pretty easy on the car. So with this new set-up im looking to well simply run the **** out of it (lol). MIL.SPEC how much would it be for you to port the intake manifold and the throttle body? But I really want to start building my motor (bottom end) so what parts should I start looking for exactly? and if someone is selling something I could use please let me know.....Thanks for the input Zack and its good to hear from you.
