Bolt On Turbo Vs Normal Turbo

wat is the difference between a bolt on turbo and a normal turbo and which one is better

Blunt answer: read the how to turbo an N/A Skyline thread.

Short answer:

Factory Turbo uses low compression motor, the motor is stronger, and the low compression is made up for by boost from the turbo

Bolt on turbo uses an N/A motor. The high compression is used for low down torque and quick response, and low(er) boost from the turbo gives it the extra power and top end.

There is risk in turbocharging an N/A motor, reliability is put at risk, though tuning is definitely the key to a successful longer life. You can only run so much boost before you bust the internals or need to look at a rebuild to seek more power.

There are some with balls though who have been willing to defy the norm and push the limits (wytsky i'm looking at you lol) but at the end of the day it depends on the driver. Some are fine with not having boost till 3-3500 revs and being able to run a lot more top end power, whilst others want a more useable engine that boosts at 2000 revs.

The other is cost. If I was to do it over again, i would get a turbo skyline to begin with, or do an engine swap. Other things to consider of course, unless you have a GTV, is the brakes, gearbox, lsd, just to name a few.

My advice to you is to read through the how to turbo your N/A thread as this is pretty much all covered. Best to ask questions there, there are plenty of DE+t people there that can answer them.
