20g ?

[90_laser_rs]

hey guys i found a 20g turbo with dump for sale for 350 no shaft play....i have an evo8 fule pump and the stock 450s. so can i run this turbo just bolt up and go??? thanks guys.

yes on stock boost.

You will max out your fuel system around 4500k to 5k, regardless of stock boost setting or not you will have boost creep so you need to be very careful. I would invest in some injectors and fuel pump prior to installing the 20g.

really wow i figured i was in need of 550s sweet....also this may sound bad this is my first turbo car and i was wondering how much would it cost to get a tune if i did go with 550s?

boost creep has nothing to do with the fuel system. boost creep has to do with the efficency of the exhaust system and the ability of the wastegate to bypass flow from the turbo.

u need apexi safc for tune , on ebay u pay from 100 to 150 for this unit

That will work once you get bigger injectors, doesn't matter how much fuel you can push through if the injectors wont fire them off.

and thats what i have been told...but i have no clue how to tune...is it like a plug in and it does the work for you....or is this just for the shop to play with?

I believe he meant that even if you set the turbo on the stock boost setting to not run out of fuel, you might get boostcreep and still run out of fuel because of it.

Look, A safc wont do anything for you if you are on stock injectors. You can't make them provide more than 450cc so until you upgrade your injectors you will run out of fuel. If you have a eprom ecu you dont need a safc. Hell, I could mail you a chip with a proper tune for what ever setup you have that will give you a baseline tune.

bigger injectors and a way to tune. do you have a logger or a wideband? you dont want to go lean. and you will most likely go lean at stock boost with a 20g and 450's. in turn burning valves and other expensive things like that. if you have no way to moniter your fuel then i wouldnt mess around. thats just me.

ok so i would be good with 550s then...and i have heard the turm eprom just not sure what it is...were can i get one.

no i have been in the dsm world for about 4 mounths i have learned alot just not enough just yet...the car i got has made me learn alot due to all the probs i have fixed timing belt gaskets clutch ect the guy told me it had a big 16g and i later leared it was a t-28 ...im the kinda guy that wants to do all my stuff right no hacking or fast ways.

Ok, an eprom is a different type of ecu that allows you to swap out the chip as required. You can open yours up and see what kind of ecu you have. 550's are good but for a 16g but for a 20g bigger injectors would be better. An Evo comes with a 16g and 550's so if you're going to be flowing more air then you will need more fuel.

Here is what I believe you need:
650cc injectors or higher
AEM wideband
Eprom ecu - check if you already have that
hallman boost controller
190lph or 255lph fuel pump - ForcedPerformance sells a great 255 that is quiet

Building a car up takes time if you are limited on finances. Get the 20g and shelf it until you are able to take care of the fuel issues.
