Is there any point to getting a good SR20 and then rebuilding it. Such as new rods, pistons, balancing the crankshaft. All that. Someone told me it was pointless because it’s already a strong motor as it is and new pistons and stuff might rob the motor of power…? I dunno if that’s true, but what do you think? Is there any point in doing it? I was just wondering because I would like to upgrade the turbo on the SR20 and other mods and then turn up the boost without damaging the engine. I thought aftermarket internals would allow you to turn up the boost more then the stock internals? So is this true or not? Thanks guys. ---

Definately go for it.Although it won’t make your engine bullet proof it will be pretty damn close.You will also be limited in the power that you can make if you don’t do the internals. ---

Usually internals are done when the horsepower limit is met on the stock internals and you are in need of more hp. Then you swap out the internals and do the full job from there. Although, when you buy the motor, you already have the motor out of the car, so it would make the job ideal. Internals are by no means cheap. Look at like a $3000 job just for the internals and some labour. Everything needs to be taken apart, balance, resurfaced etc etc. Personally, if you don’t see yourself doing bigger turbo within the next 4 years, don’t worry about it and save up for it. ---

So $3000ish for new internals and everything? That’s cheaper then I thought! Oh, I plan to upgrade the turbo within 1 year, lol. To a T3/T4. ---

Well the pistons and rods are about $1000 right there, then bearings, rings, and all of the other parts, so I"m not too sure how many more pieces are needed there. Then the labour. Depends on what you want done. I would think in the $1500 range just for that labour for the basic stuff. More in depth, obviously the more money. ---

Considering what I have seen on Freshalloy, I say build after you exceed the limits of your combination. Inadequate tuning can be the most dangerous aspect of driving any engine. When building follow a proven combination, unless you have the money to do things more than once. ---
