I have K24's on the car right now. Have K16billets from Sambo that I was going to try to install soon. Can I slap them on without a new tune or do I need to get the car tuned right away?

I was gonna throw on my 997.2 intercoolers tomorrow with the help of some friends and figured we might tackle the turbo's also while we're at it. But if the car needs to be tuned in order to run right then I will hold off.

 

if you have a epl tune for the k24s you might be able to get by... not sure about the boost though since your on after market Wgs now... so be careful....

 

+1 on them. i have sambo's turbo's.. they're great. you're gonna love the quicker spool.

 

You should be able to run them... But I would not go WOT, under any circumstances, until the car was retuned. Even a momentary lean condition can damage the engine.

 

I would loosen up the wastegates first so you dont over boost,,rather be safe then sorry..
You can always tighten them up to get in the boost range..
I would also call EPL,Tony,for his advice with his tune...
Good Luck and Enjoy your new rocket..

 

Im wondering something similar, but the other way. Can I run a k16/16g flash with stock turbos until I have the time (and money) to get the hybrids?

 

If you are not getting into boost (or VERY little, as pulling lightly onto a free way) you would be fine as the ECU will adapt under closed loop. You want to make sure your car does not go into open loop (as full throttle runs or heavy load), being it pulls its timing, fuel etc off of the ECU's saved maps and those maps are for a K24 worth of flow and spool.

I hope that you just need to run this way, because you are just getting a 2 for 1 labor set up and you are planning to call EPL the following week to get a proper tune.

I would be VERY interested in your review of the k16Billets vs K24 after the tune coming to overall power, power delivery and spool. Please make sure to do a full review for us here at 6speed!

You are most likely going to be running lean if you on any significant boost levels without having atleast a 5 bar.

 

With the stock WG's I agree you should be cool till you sort it out. Keep it under 1.1 bar.
Then with the injectors and proper tune you will feel the "update"!

Another question, I just didn't want to start a new post.

I put on 997.2 intercoolers tonight and followe the instructions by earl. I did not put on the new turbo's, still have the K24's.

My question is, with these new Turbo's it took a lot longer to build up boost. I did finally hit 1.1 or 1.2 bar but it took a while. Is that to be expected with the intercoolers or is it more likely that I have a boost leak somewhere?

 

Sounds like a boost leak. From all I have read (and in my experience with upping intercooler size on other cars), the lag difference with the 997.2 should be imperceptible.

 

Did you need to upgrade your clutch for this turbos- or is that the expectation?

 

Yeah the pressure drop should be un-noticeable (super tine amount) so somethings leaking. Pressure test. What hoses you have? They (most) clip in to the 997.2's a bit funky. Can you do a pressure test?

 

Why risk it?

Get a re-tune and do it right. The $2000 cost of a tune is going to be insignificant compared to a $15,000 rebuild when you blow up the motor from boosting where there isn't enough fuel allocated on the map.

 

Oh, I'm getting it tuned. I was just asking if I could install the Turbo's myself first and then get it tuned if I needed to take the car somewhere.
