Which Rtek7 should i get???
I got a s4 turbo 2 with a s5 motor with some bolt-on and a bigger turbo then stock i want to raise the boost but im not sure of which Rtek to grab in the process of buying a AFC and a Wideband. Im looking to push like 10psi normal n maybe like 15 racing if thats safe?? can any bodi help me out new to the boosted cars :icon_tup:
|
2.1 and no AFC > or 1.8 and AFC.. can you say, timing?
|
just go for the 2.1, it's a simpler and more powerful solution than the 1.7/1.8 + SAFC. and you get datalogging, timing control, plus the ability to adjust cranking fuel to prevent flooding
|
1.5, because you didnt say you upgraded injectors or anything.. im rocking 1.5, plan to step it up once i get injectors.. its only like $30 or so to upgrade the chip from 1.5 or so
|
but he said he already upgraded his turbo, why would you think his stock injectors will support it?

im not sure wat cc my injectors are the guy i brought da car from had injectors that was too big and was making it flood alot i think the s4 injectors are in there. what cc are the s5 turboii injectors?
|
so if i get the 2.1 i dont need a acf? n it depends on how much boost i wanna run for the secondary injectors cuz i was thinkin bout having 550cc for both, how much boost can i go with the 550 untill i need bigger ones sorry 4 the noob questions
|
There's no point to an AFC if you have an Rtek 2.1.
You're going to blow the engine if you really do have stock 550cc injectors. You need to figure out what this upgraded turbo is, then get appropriately sized injectors. The stock turbo can max out stock injectors, let alone anything larger. Without any information on size/air flow potential, no one can tell you how much boost is safe on whatever turbo you have. My suggestion would be very little. |
I want to know wat turbo it is but when i brought the car the guy game me the turbo he said it was a upgrade never told me wat it was and it was blown. I had it rebuilt and installed on the car and the guy that did it said he cant figure out what it is. He had do extra to make it fit he did a good job tho. I guess ill get the 2.1 mines well get the best n no need for a afc rite?

Iif you arnt sure about things the 2.1 is also the choice. No need for an AFC OR a FCD
get this plus a wideband and you can keep a good eye on your AFRs. Don't do raise your boost until you can figure out the fuel levels going to the engine. Stock turbo injectors are 550x4 the nice thing about the rtek is that you can buy two 720s and throw them in, then just click a box. Then if you add two more 720s click another box. |
Ill get the 2.1 and all new injectors thanks for the info guys
