My Porsche Car is a 02 GT2, with 11k mls, mostly stock with Cargraphic Export Exhaust, Evoms DV's and recent EPL tune.
Just purchased Protomotive K24/20's form a fellow 6speeder.

Looking to find out routes to add on some mods, but keep stock appearance when one opens the engine lid.

Was considering the following, because I might be able to keep stock GT2 clutch, fuel pump and IC's:

Upgrade to 1 bar wastegates by (Maker ?)
K&N or (?) Air filter replacement (inside stock box)
60p injectors with stock FPR, or stock Injectors with 5bar FPR. (Maybe 60p injectors, so she is ready for the possible next step, or..?)
Re-tune, boost setting 1.1-1.2 max (maybe only 1.0 -since Ihave only 91 octane available)

Tuners, please let me know how far off the mark I am. Any advice is sincerely apprichiated... Thanks to all on the forum.

 

Well usually if you get the 20gs they are with upgraded springs.... so if yours are not not sure why...

60 lbs with 3.8 bar is fine...
BUT your real issue is the intake piping, the ICs, etc...
without the piping from the airbox to the turbos and the ICs your car will not like it.. especially on 91 octane...

we did the first 20g a few years ago.. my business partners 2001tt...
but that car has a lot more then just 60 lbs injectors...

let me know if we can help... we have a lot of experience...

the stock gt2 clutch will not hold the 18g or 20g for long...

 

the 20g turbos need air so that is why people do the blow through MAF and fender well intake kits to allow the turbos breathe.

i know of someone who put inlet pipes on their car on gt30's and it still didn't have enough air removing the stock type paper filter on the dyno showed a 50ftlb of torque increase!

your likely looking at blow through setup, big intercoolers, clutch (dual plate or triple) retune and second fuel pump to make the full use of these bad boys.

 

+1
Most guys are not willing to spend on the important stuff before they buy into the senseless items....
this is what the car needs besides the pump and injectors... I always say to it once do it right... been there made many mistakes...

 

if you dont have enough to do the new intercoolers and the blow through intake setup then start with the fuel system first and get it tuned properly.

but when you upgrade to the other pieces you will have to retune each time.

and if you upgrade one at a time you will have to think about the intercooler coupling sizes and such, and with 20g's you will want as big of itnercooler piping as available as these are no joke big power turbos.

example 20g's @ .8 bar will produce as much power as k16's @ 1.2bar just in shear airflow (these are not actual numbers just an illistration for the poster)

so that is something to remember, without breathing mods IE intercooler and big piping these turbos will spool 3-400rpms slower then if they could breathe

 

if you dont have enough to do it all , i would wait and do everything together, so you dont have to pay for two different tunes etc etc.. but OS is right you need alot of supporting mods or they will choke on high boost.

 

Agreed with Markski, OS and UNVMY. I listened to Mark and I'll be a happy camper. You should do it once cuz at the end of the day if you do it 5 times it'll cost you more then saving getting all parts doing install and done.

 

+1 Agree completly.

 

I even strongly suggest not putting them on until you get the intake at a minimum...

 

Looks like you guys are saying that one should start collecting support mods and install all at once. The K24/20 are not going to do any good with the "keep it stock look" then...

Oh well, so far for keeping things modest. That being said, I bought a GT2 and therefore, modesty went out the window anyway....

 

whats the cost on something like this in parts??

 

you can check here for more info:
These are the same parts as on our 1000+rwhp cars...

You could always get the Y pipe powdercoated in crackle black and use black hose to keep a more stock look in the engine bay, all be it without the air box.
