New parts to be installed: k24/18g upgrade. will be adding 60lb injectors... stock internals, usual bolt ons. 97 rated octane pump gas. Softronics Flash.

The RPM gauge turns red mid 6k but what's the OEM rev limit? I hit 6800 the other day (already running a softronics tune on k16s/stock fueling).

What is the optimal shift point (in terms of engine longevity vs power band) given new parts?

What's a safe rev limit given the new parts?

would like to ask a limit to be set on the softronics flash. Presuming it'll be about 1.2bar + there bouts w/o EBC.

That brings me to the EBC. Website states an EBC is required to bring boost from the factory limit of 1.3bar to 1.6bar. I'm thinking... stock is 0.6bar on smaller turbos, my car's got nil internal work, not even thicker head gaskets... is this safe, did porsche really over spec/engineer this much?

Having owned and tuned several JDM cars, (rb26 GTRs, a Supra and an Evo), generally speaking stock boost is at 0.6~0.8bar, one could go safely to 1.2~1.3bar max with the right parts. Even then, while achievable, reliability goes south, quickly. So, 1.6...really?

Don't care about peak or dyno numbers. Use this car to get to and from work, and just want reliable power on demand, all the time.

Any advice would be appreaciated... before I break something.

TIA

 

According to "Speed Secrets", optimal shift points are the overlap of the torque and HP curves, which on a stock turbo would be about 2500-5500 rpm. Different tunes and turbos will of course change the curves so you'll have to do some research for the K24/18g's.

 

No need to run a 18g to redline.. shift at 6200 to 6500 for best results... redline is probably set to 7200 or so...
you really need to ask the tuner what boost, fuel, and proper tune you should be running not the WWW.... you will get many opinions leading only to what you referred to as "Any advice would be appreaciated... before I break something."

Call/email, fax, show up at the doorstep, send a a **** star dressed as UPS driver(LOL), etc etc whatever it takes... your tuner- Softronic and only he can set up up correctly in your case...
good luck

Landjet: thanks will search for some dyno graphs.

Markski: Advice very much appreciated. Yea may be I'll have to send an overseas care package from the red light...

Would changing the final drive (believe only smaller ratio available for this car) to either help bridge turbo lag gap or stay within the power band longer?

thnx

 

Wait... Markski, you have pornstars that come to your door and flash your car? How do I sign up?
