20 lbs on stock bottom end

[GSleeper]

Is it possible? Vehicle is a 96 GSX so the 4g63t motor. Will I have any clutch issues? Anything I should know about? thanks

I've done it at the track a few times. Completely stock internals (block, head, head studs, etc) And I run 18 psi daily.

buddy runs 24 psi on a fp red daily..

Awesome now how would I be able to approach this? Evo16g, Walbro FP, (what injectors), how to tune?

thanks

don't just turn the boost to 20lbs. Buy a datalogger first.

evo 3 , 550's , 190 rewired, dsm link..

Wow this is going to be great. I'm getting rid of the n/t w/t for a GSX hoping for better results. I would need an FMIC upgrade though right? The SMIC is too small?

Of course 20psi can be run on the stock bottom end. WITH the correct supporting mods.

You will need the proper fuel upgrades, intake and intercooler upgrades, turbo upgrades, gauges, datalogging and tuning devices, exhaust upgrades, drivetrain upgrades, etc.


You can't simply turn the boost to 20psi and hope for the best. It really depends on the turbo size, but to run 20psi on a 2G you will need at least the following:

- 16G or larger turbo for maximum efficiency
- A properly sized aftermarket side mount intercooler or front mount intercooler
- At least 550cc injectors for the 16G - larger if you want a bigger turbo
- Upgraded intercooler pipes since the 2G uses plastic for the upper IC pipe
- An aftermarket Blow-off valve that properly recirculates the air back into the intake before the turbo
- An upgraded Walbro fuel pump, at least 190lph but I recommed the 255lph low pressure pump
- At least an SAFC to control the injectors, but DSMlink is highly recommended.
- Most likely an aftermarket clutch since you will be putting a lot more power to the ground. ACT 2600 is your best bet.
- Boost gauge for monitoring boost levels
- A datalogger of some sort to monitor timing advance, o2 levels, and fuel trims to tune the car. Again, I recommend DSMlink, but a Pocketlogger works well. The most important thing to monitor is knock sum, but only DSMlink or a standalone can do that on 2Gs.
- A proper exhaust system that will help spool the turbo and maximize efficiency. At least 2.5" turbo-back with either high-flow cat or test pipe.
- An aftermarket K&N style air filter will also help airflow.
- A manual boost controller to adjust the boost.


Once you have all of these parts and the car is properly tuned, you can expect to run 20psi with problem.

Nope, you don't need one, although it would help. I'm running with the stock smic right now.
