Easy turbo II hp upgrades
What are some easy hp upgrades. Is the RB exhaust and FCD really worth it?
|
the stock exhaust is very restrictive free up the exhaust will allow for quicker and better boost. will need the fcd and the wastegate does not flow great you will need to port it if you have a better flowing exhaust. that is a good upgrade.
|
Don't do all of those upgrades without upgrading your secondary injectors and fuel pump. The stock fuel system can barely handle stock boost levels.... This is probably the number one reason why so many fc motors pop so quickly
|
Reading FAQ's and upgraded fuel pump seems to be #1
|
stop MAKING threads and start READING them.
|
Do you really need upgraded secondaries and fuel pump to get aftermarket exhaust? Never heard that before.
|
the short answer is yes. the long answer is, it depends how much your boost climbs from that exhaust and how good your stock fuel system is running.
|
plenty of threads on this..at least 2-3 a week. its easy to get hp from s4. doing it right can be costly. like everyone stated above.
upgrade fuel pump(walbro 255) Rtech(1.7) RB full exhaust ported wastegate 720 or 850cc secondaries cleaned primaries possible short ram new plugs/wires boost gauge All basically one big step process done right though..and of course car should run great before these mods(tune up) these mods cost round $1700 though |
^^ thats exactly what you need.
|
RB full exhaust plus Rtek 2.0 computer seems to be the best way to go.
|
its better to upgrade than refurbish!
real life isnt like gt3 |
you can do it for way cheaper than that. you can get a used, non RB exhaust, full turboback, for probably like $600-800. you can get away with an SAFC and FCD, both would be about $150 used or less. two 720's used in good condition are like $100 or less, cleaning primaries is cheap... I'd say $1000 is possible if you get good deals. maybe less.
you will need a wideband or time on the dyno to make sure your AFR's are ok though. |
you can build one for $30
|
Go with the rtek, then at least you can tune fuel and TIMING.........best compromise for cheap. And you get the benefits of the FCD.
|
Is it better to port the stock wastegate or buy an ebay one for $70? does the FD wastegate fit and is it better?
|
^yeah but he didnt specify which series. I was under the impression that they only make the rtek for the s4's correct?

My assumption was S4, since that is the majority of TII's on this board. |

I just finished my major upgrades. Took awhile
Get and s5 turbo manifold and hotside-Port the wastegate Cone type filter with TID Full RB system. With the ported s5 hotside you will have no boost creep problems. I run 5.5lbs of boost and it's plenty of power. Anything more and you have to touch the fuel injectors.DO NOT upgrade with out the ported wastegate. Do these mods first then you have some basic covered. You may also want to do safety mods-such as the replacing the fuel pulsation dampner,replacing coolant hose and vacum hoses. A tune should be done first if not done recently. |
