Hey guys, as you all should know, I have just finished off this school-year and am now ready to get my RB25 240SX running. I have bought ALL the necessary parts, and I should be working on it all tomorrow and Sunday. In other words, I should have my RB ready next week at the latest. I have a few questions for you, and I hope you can help me out. And yes, I have used the search button, but I couldn't find any answers to my specific questions. Thanks, to all of you who will help me, and to all of you who would just rather flame me.

Where can I find radiator hoses to fit my setup?-sr20 koyo radiator -rb25det s13 240SX-Greddy Intake ManiI'm almost sure the Lower 240SX Hose will work fine, but the upper hose is what I'm having trouble with, it must cross over from the right side to the left. aluminum would be great

Do I use the 300ZX TT fuel filter, would there be a problem using my stock 240SX filter?

What should I do about a broken Stud in my Exhaust manifold?

Does anyone know a source for a direct bolt-on Aluminum driveshaft for my s13 rb25det with TopHat mounts with stock 240sx s13 crossmember and stock 240sx s13 diff?

Almost every RB swap I've seen has included the purchase of an Oil Catch Can.. How important is this?

For the RPM and Speedo gauges, I have chosen the LSAUTO full conversion, its cheap and easy, what do you think??

the SR radiator has the upper hose neck on the wrong side (hence suppose to use a KA radiator) you'll have to probably use a metal pipe and some elbow pieces to make one up, if not look what you can find at the back of a parts shop. Take a look at some of the SR guy's setup using a KA radiator with their swaps. Same concept.

Don't skimp out on the 300zx TT fuel filter it cost next to nothing like $15 from anywhere. I wouldn't use a 240sx filter

Exhaust stud needs to be extracted. If it has alittle or some of it showing (like sticking out) get some lube on it and get a set of vice grips and work it out. If not and its cut flush or inside, you'll need to drill it out or use a special extractor tool.

Catch can is if you don't have the hoses hooked up to your valve cover and such, not very important at all but it kind of replaces those cracked or broken hoses you might have.

The driveshaft situation. For a direct bolt on would be to buy directly from Top-hat for they sell a driveshaft for their mounts. If not i believe you can use one that JGY sells.

LSauto tech is straight foward spend your money get what you want.. nothing wrong with that one.

Hope that helps
