The reason I ask this is because I am rebuilding an Rb25 due to broken ringlands and I am looking to get a little more power out of it. The problem is (other than I am on a budget just like everybody else) I am going to be taking the engine out of the skyline and placing it in something else later (hopefully a datsun 240z g nose or a 510). I would love to build up the R33 but I cant take it with me when I move back to the states. So that being said, I want to try and stick with parts i can use with the swap. I wouldnt mind upgrading the injectors but I dont feel like changing the fuel pump, so if the fuel pump cant feed anymore than the stock injectors can spray, then I will wait till i get it back to the states to change it when it is in its more permanant home. As for the ecu i dont really know when it needs upgraded either. If it can support more than the fuel pump then i will leave it alone, if not what is a good upgrade to take advantage of the stock pump Also what other mods can I do to make the most power without changing the fuel pump. I know this is kind of an odd thing to let limit my power but I am really just wanting to get a little extra out of it till i get it back in the states. once I get it done it prolly wont be spending very long in the skyline before I have to start pulling it out again (maybe a year if i'm lucky). Then I will be shooting for prolly 375kw when it finds it's new home in a car back in the states. if you have any tips or things I should do to make it more powerful/reliable in the long run or that will save me time or money when rebuilding or things I should replace now while I have it apart to support the 375kw later please feel free to let me know. Sorry for all the questions but I'm a noob to skylines.

Just called my personal mechanic back in the states (aka My father) and he gave me the same advice. So it sounds like a hone is what I'm doing! Thanks for the advice and the second opinion.

As the title states I cracked a ring land on #5 and scratched the bore. I have heard people say that you can just go over it with emery cloth and call it good. I know this will work in some cases, but I also know it has its limits. I dont really have any way of measuring the depth of the scratches but mostly it is just very light and I cant even feel it. There are 2 spots that I can feel although they are also very light just barely enough to feel, probably only .003" deep and about the same width at the worst part. I know for a high hp engine any scratch at all is probably a no-go but my plan is just build it back to stock engine specs and stock boost for now. will a new piston and rings and a bit of emery cloth do the trick or do I need machine work. I know it is probably impossible to tell for sure without being here and seeing it first hand but if you have any expierence with this, please let me know what worked for you. cheers

sounds like thats what I'll do then. I don't plan on taking the cam gear off at all so no need to worry about it being easier with the head on the block and I plan on marking the postition of the belt with a paint marker on all the gears and the belt so it should be easy to get back in time. Looks like I just need to pull the lower timing belt cover off and loosen the tensioner. Thanks for the advice.

as the title states Can I get it off of an rb25 with out taking off the cam gears. I am thinking of taking out all the bolts and seeing if I can lift up in the back and slide the belt off the front. Does anyone know if this will work or not? I tried taking off the intake side cam gear but it's on there pretty good and I don't know how to get it off. I got the big bolt out but it's still on there tight.

I was thinking a blown headgasket at first and I do have one on order but when I took the intake tube off and the compressor side of the turbo was full of oil my assumption was that the seal in the turbo was bad since the oil would have had to make it all the way through the intercooler to the turbo and that didn't seem very likely. There was quite a bit of oil in there, more than I would think would come from the breather tubes. but maybe I'm wrong, like I said this is my first time working with a turbocharged car and I'm quickly learning that thing are a little different than NA engines. If you have another Idea of what it might be then let me know and I'll check it out. I'm open to any suggestions. My thought was that the oil was pushing through the seal into the compressor when boost was low and that the boost pressure was pushing through the seal and down the oil drain tube when boost was higher like at full throttle. but that was just a wild guess. I did block one side of the compressor and blow on the other and was able to hear air coming from the oil fittings but to be honest it was only a little bit, that could be normal idk. When I brought the car home I filled it up with oil and stayed off the boost and was able to drive it home (about 10min) without the dipstick blowing out. but it smoked badly any time I opened up the throttle more than barely above an idle. I will be doing a compression test as soon as my tools arrive but as for right now i have no idea what it is. I do know that it had a pretty bad misfire when i drove it home. I assumed it was oil on a spark plug (maybe 2 plugs) but really not sure till I get my sockets to pull it out. Thanks for the input.

Thanks for the advice, I'll keep an eye out for one.

Well, I'm a skyline noob. I just got a 95' r33 with a bad turbo. I thought the head gasket was blown till I pulled the intake off and it was full of oil. I traced it back to find out that the turbo was leaking from the compressor side. This is my first turbo car not to mention my first skyline. I want to use the car as a day to day driver. I dont want to sink a bunch of money into it yet. just want to get it back up and running. But as you already know the stock turbo can be a bit hard to find and pricey when you do. I've had several people tell me that if anyone can help me it's you guys. so, I guess my real question is. What is the most easiest/economical way to get this thing back on the road untill I decide which direction i want to go with building it? I will be doing all the work myself. I dont have a lot of resources but I have a lot of exp. wrenching on motors. As long as I dont have to fabricate an exhaust or do any custom tuning that would be best. one of the biggest problems is I live in Germanyand speak very little German, not to mention not many skylines around here, and even fewer wrecked ones. I'm kinda stuck with buying parts online. Which is even more difficult since I wont have internet at my house till the end of next week. I have to go to a cafe to get internet for now, so I have a limited amount of time to search. How much oil was in the intake you ask??? A lot! it was puddled up in the intake tube and the compressor side of the turbo. It was even puddled up clear up by the throttle body. It smoked very badly the entire time the motor was running. I didn't notice any noises but my hearing is very poor so it may have been making noise idk. before I bought it, I was trying to help the previous owner figure out what was going on. I ran it up to full throttle on a short drive (.5-1km) and it blew the oil dipstick clear out of its hole and emptied the contents of the oil pan under the hood. I think it must have been pushing the boost back through the drain line of the turbo and into the pan to blow the dipstick out. any other ideas? probably a common question but what is the easiest turbo to fit to an otherwise stock(ish) motor if I cant find a stock replacement? Sorry If I'm asking a bunch of repeat questions but like I said I dont have a lot of time to search around without having internet at home. Thanks in advance, any information is greatly appriciated.

Yeah, thats the thing. I live in Germany, not many skylines around here, and even fewer wrecked ones. I'm kinda stuck with buying parts online.

Is it worth doing for a quick fix?
