I'll just get to the point, I told my brother I was thinking of upgrading to a evo3 16g turbo and everything else needed to complete the upgrade. He has a Dodge neon SRT-4 and upgraded his turbo to a big wheel stock turbo. the thing is he upgraded as turbo and everything else without upgrading his internals and you can guess what happened next. And he tells me then I need to upgrade my internals in order to safely run the turbo setup that I'm thinking of. Now I've seen a lot of people here while searching through the comments saying that they didn't upgrade their internals for this type turbo upgrade. But am I wrong or is he right? Any help would be much appreciated thank you in advance :)
 
You can run stock internals and max out a evo 16g safely with supporting mods. Only thing I'd replace are head bolts to studs. On a 2g, the rods are the weak link above 4-500 whp but some have pushed well beyond that. Personally, I've daily 407awhp 2g with stock internals for a several years without any issues.
 
Tell your brother that Mitsubishi 4g's are MUCH stronger than Dodge Neon SRT-4's and see what kind of discussion happens ROFL
and that you will CRUSH his puny SRT-4.....add that part too.....:p
 
You know we are just having a little fun on a gloomy Monday!!! :)
There is no reason to upgrade internals on your motor for the small upgrade you are doing. I have a stock 6 bolt that is ready for a HX35 Holset turbo on the stand, on stand by. My son built it with my instruction and beside me while I built my motor for my 92 Auto Talon. He did great and all we did was, since it was apart, put ARP rod bolts and head studs in it. You will be just fine and shouldn't worry. :thumb:

Haha we all need that little push on Mondays haha. Man congrats to you and you're son! Thank you for the knowledge! I already have ARP head studs installed, would I also need ARP rod bolts? I know you mentioned that in you're post
 
I am inches away from putting my Holset HX35 on with stock internals and upgraded head with top of the line head studs. I think he put rod bolts in as a while I am here type of deal. I haven't touched mine and it should be fine.

Supporting mods are key I think

Nah, My oldest son WINDOWED a 7 bolt by breaking the rod just above the journal throw but it didn't break the rod bolts and they were stockers. If you replace rod bolts you have to have the rods resized. You are just fine.
 
The factory bottom end on a 4G63 has been known to easily handle 400 WHP, many have gone beyond that. The blocks are stout due to Mitsubishi overbuilding them for rally racing. That's why so many people would rebuild their bottom ends using factory rods and pistons when shooting for 400-500 hp levels. With that said, it will obviously depend on the condition of your bottom end. Not all stock blocks are going to be healthy enough to run that sort of power.
 
I would agree that you don’t necessarily need to upgrade your internals, but that the condition of your bottom end is likely to be the determining factor of whether or not you end up making a nice port hole in the side of your block.

Last winter I fully rebuilt my bottom end using the original rods, NPR oe replacement pistons, and ACL bearings all because I wanted to make sure my engine was healthy enough to support a 16g without blowing up. It’s seemingly holding for now.

Without the proper maintenance and supporting mods for your build, you may end up wasting a lot of time and money. Keeping that in mind might save for a lot of future headaches.

Most stock block 4G63s around are going to be pretty worn by now. Unless you have a low mileage stocker that's been well cared for and maintained regularly over the years, chances are it's going to be in need of a refresh. And if it's been sitting for years with low miles, that isn't necessarily a good thing either.

Always a good idea to refresh a bottom end when looking to make more power, either with factory rods/pistons or forged.

I have a GVR4 with 220K feed by a Big 16G 1150cc injectors on E85 with stock internals that I daily, when the trannys not broke:p
