QUOTE(wickedz @ Jul 14 2008, 07:53 PM) I have the 6 bolt crank so I figured it should be able to perform ok on low boost, internal wise.
[right][snapback]183161[/snapback][/right]
the crank isn't the issue with the n/t cars, neither are the rods. it's the pistons. two reasons: 1. the stock compression is 9:1 for n/t (not the worst thing) 2. the n/t block doesn't have oil squirters (still, not the worst thing) 3. the stock head gasket isn't all that great (the worst thing) higher compression is ok with lower boost, and you will actually spool a little quicker. The lack of oil squirters means that the pistons will get hotter than the turbo blocks. The oil squirters are designed to open under high RPM and heavy throttle and squirt oil onto the bottom of the pistons, cooling them. Without those the increased piston temps under boost may cause detonation,,,if that happens too many times with the higher compression the head gasket may fail. But, if you put 8psi or less into that engine and tune it properly with the right fuel pressure regulator, AFC or other tuning mod, and don't spank it like a rented mule you will be ok. Check if you can see the number on the tranmission. I'm pretty sure they are the same between turbo and non turbo models on the 1g but can't remember for sure.

QUOTE(wickedz @ Jul 15 2008, 10:46 AM) wow thanks for all that info pwee05. Can my block have oil sqirters or do I have to do a swap? How about my fuel delivery? [right][snapback]183373[/snapback][/right]
I prefer a block without oil squirters, but I also always use forged pistons. Usually Wiseco or Ross. You can install oil squirters by drilling and tapping the holes into your block and then threading the squirters in them but that's a waste of time and can introduce metal shavings into the oil system. check your injectors. if they have a blue top you are good to go with fuel, just stay around a stock boost level. 10psi or so. if they don't have a blue top read the tiny part number on the injector's electrical plug. it should say 450 in there somewhere. if it doesn't you need to hit up Ebay for some 450cc injectors. normally $30-50

QUOTE(4G63Attack @ Jul 14 2008, 09:10 PM) you can keep your stock internals. I have hear other people who turbo there non turbo car and running pretty high boost for a couple of years and nothing happen. [right][snapback]183200[/snapback][/right]
My mitsu mechanic who is rebuilding my tranny turboed a 4g63 nt. Ran 15 lbs of boost on a td05 for two years before he blew a piston ring.

QUOTE(smiffboove99 @ Jul 15 2008, 02:21 PM) Several years ago I was in the same situation. I was looking for a way to make my non-turbocharged car into a turbo. The truth is, it was easier, and even cheaper for me to just buy the turbocharged car.
It's just a lot of work, and a lot of cost to turbocharge these cars when they weren't originally designed to be. [right][snapback]183512[/snapback][/right]
I don't 100% agree with this statement. While yes it is easier and more cost effective. If you do it your self it can be a GREAT learning experience.

QUOTE(EMC 3000gt @ Jul 15 2008, 02:51 PM) Figure in a reliable DD into the budget [right][snapback]183541[/snapback][/right]
I think he has a 3g for a DD unless that was someone else. It's too early to re-read the entire thread :P QUOTE(wickedz @ Jul 15 2008, 02:12 PM) Militaryman--- The TDO5 is the larger stock turbo am I correct? I wanted to buy a complete turbo kit off ebay or maybe etreampsi. Can I do this, Buy the upper hardpipe, ect ect? If the cause of the 4g63nt has issues,due to horrible headgasket, then I will buy a complete engine gasket kit as well.
I have oil chillin on top of my valve cover, BUT its not coming from my spark plug holes, nor my oil cap. Now why am I gathering oil on my valve cover???? I checked it for cracks, ect and its clean. [right][snapback]183507[/snapback][/right]
http://www.mitsubishi-forums.com/index.php...788#entry178788those are all your td05 turbos. 14b through evo III. all have varying peak power numbers, but you are correct, the td05 is the larger stock turbo between 1g and 2g cars. the 14b with the 7cm2 housing is the one to go for if you are considering that one. It will have a 7 stamped into the turbine housing on the side facing the center cartridge.

No I dont have another car for a DD. I want to buy ALL that I need for a complete turbo install and go for it. My eclipse is now in the shop for a complete AC install.
pwee can you tell me WHY I have oil sitting on my valve cover? Its not from my spark plug holes, its not coming up through the bolt areas, my oil cap is dry, my valve cover was instpected and not cracked anywhere, I installed a brand new valve cover gasket and sealant. Im just not understanding. Its gathers up so much and dont seem to collect anymore, if you get what im saying. Its always teh SAME amount chilling in the spark plug area.
Also why is 2nd gear always grinding? It happens MORE when I downshift, almost acts like the gears still spinning and when I put it into 2nd, it kinda grinds a little
