How many PSI should I run on stock??

[Red]

Going to have a turbo real soon... get in installed and tuned..

It will be the greddy kit with the intercooler... And the Profec E-01 and all harneses...

I just dont wana make my shit explode

[thelinja]

el searcho, but I think the consensus is around half a bar.

[Var]

i'd say 10-12 psi since you'll have an intercooler and it will be tuned so no risk of detonation.

[mellojoe]

on a KA? If you have proper fuel delivery, and have someone tune it .... completely stock internals ... i'd agree with 10-12psi. 10psi should put down some nice power (how much depends on turbo and other bolt-ons).

Enjoy!

OOPS! Totaly spaced out and forgot to put all my info on here...

Its a 95 240sx with 120k miles...

Bolt on power includes.... Flywheel 11lb and JIC bullet 505s ti TURBO.

The GReddy KA24DE Kit includes:

A large TD06S 20G actuator-turbo
cast-iron manifold
4x topfeed 370cc injectors with high flow fuelrail
Airinx air-intake
All the necessary piping and hardware
turbo rated for upto 460hp
programmable e-manage

I also purchased...

Greddy 240sx Front-mounted Intercooler Kit
PRofec E-01 - Boost Controller & E-manage Programmer.
PRofec E-01 Pressure Sensor Harness
PRofec E-01 External Signal Harness
PRofec E-01 Remote Switching System
E-manage Injector Harness
E-manage Ignition Harness
E-manage Pressure Sensor
E-manage Pressure Sensor Harness

Hope this helps...

Have you had a compression test recently?

[Red]

Yes... Not more the 6 months ago...

1st Piston was 182 compression
2nd Piston was 183 compression
3rd Piston was 182 compression
4th Piston was 183 compression

I also have newish plugs, performance wires, roter cap, battery, alternator, valve cover gasket, oil cap, starter, clutch disk (but its stock)

What heat range would be good?

[kbounds]

370cc's are only going to be good to around 10 psi. I think the stock MAF limit is somewhere around there too.

[Steeles]

I;d run whatever Greddy says to run for their kit..... I mean they did test it and build it and test it some more.... but thats just me

What heat range would be good?


I'm running NGK's with a 7 heat range gapped to .28 and they work fine for 10psi. :hsdance:

keyword: FUEL. u r cranking boost for an engine that wasn't design for 1. although, with all do respect to the mighty KA (i love u) and all the goodys it got (under piston oil system etc etc). 10 psi will be pushing it. So to push more than 10 PSI I'd go for Walbro fuelpump upgrade and 550 injectors then u can tune with with all ICE goodys u got. REMEMBER!! more AIR + more FUEL = MORE POWER and less detonation.. that my principle when dealing with Rotary..but again..just my .02
