def a worth while upgrade, hauls to redline. even at the stock rb20 10psi w/g it hauls. and when it craps itself you can get it hi flowed.

I think you can get away with 14psi with the stock 270's, once you get it hi flowed you want at least ca18det 370 injectors or gtr 440's.

also keeps your engine bay looking stock.

Yeah big difference feels slightly more torquey down low but yeah lots more lag but there is a power gain sorry but I don't have figures to prove any of this lol so take my word for it lol

      Rb25det Belts Change

      By joshuaho96 · Posted

      Everything I found online said never use it because it'll dramatically reduce belt lifespan.  No, but I have seen excessive v-belt tension cause the audible bearing noise from excessive radial load in things like alternators. So don't overdo it. Ideally you set it to manufacturer spec using a proper belt tension guage. I tried the "clicker" type gauges but those cheap things are trash. They read way too low even when you're careful.

      This is kind of where I've ended up for the most part. It's easier for me, easier for shops that don't have to deal with my weird criteria/picky standards, etc.

      Will do. Suprised if it's not the starter motor considering it's 30 years old. Will get a volt meter though. Battery is close to new.   Cheers for your help, always appreciated.

      This almost never happens these days. No. Clean your battery terminals and make sure they are tight. Use sandpaper on a dowel if you have to, to get oxidation off the inside of the terminals, particularly on the -ve. Check the earth cable from battery post to chassis ground and engine ground. Make sure the contact surfaces are clean - including the threads on the bolts that anchor them - because that's where a lot of the contact occurs. Wire wheel on a drill is a good thing for this. Make sure the crimps on those cables are all sound. Assuming none of that causes an improvement: Check the battery voltage after it has been resting for a while. If it's at the lower end of the range, put it on charge for a while, then see if it will crank better.

      I just checked my belt, it wasn't super loose but I could bend it past 90 degrees a small amount so I tightened it up and for the first time ever my car didn't crank first time, had to crank it again lol. Don't know if that was because I tightened the belt or if it's my starter motor going out (been having slow starts for some time). Coulda also been when I was recording I didn't crank the key properly and it didn't save the recording lol.   Is that a thing if you overtighten a belt it struggles to start?
