AGP RS49T vs Big 16G evo III

[2DaTrakNow]

Im looking at two turbos and have no idea what to get. My options are the RS49T from AGP turbos(about $850) OR the Big 16G Evo 3 turbo for about $560. I want to have a turbo that will obviously last long and i wont want to replace in the future (due to lack of power coming from the turbo). My current mods arn't much, but in the somewhat near future I am going to be doing alot of modding. Any ups or downs from either turbo will help. Info such as spool up time, max boost, maintenence, tuning, etc. i will greatly appreciate. Or any recomendations for other turbos would be great too!

Facinating. You did mention drivability issues though, I'd assume to mean idle quality and low/mid rpm throttle response.

There have been different results with different setups. That's where the drivability issues comes in to play. No one knows what will happen with your car.

Since i want something that i wont regret later on, i should probably go with the 50 trim, just because the evo will drop off and i will be drag racing a little bit through out the summer. When i get the 50 trim, and if i get a 255 fuel pump, and 650 cc injectors, will i have to have a dsmlink to get the most power out? OR will a SAFC and a MAFT be good enough for tuning?

I know this is kind of the wrong spot to ask the question, but beings how everybody in the thread has said something about them. What are the advantages of having a DSMLink, compared to having a wideband, SAFC, and MAFT. Also, what are the disadvantages.

Dsmlink is a tuning device that sort of bridges the gap between piggybacks (safc, etc.) and a stand-alone (Aem ems, etc.). It needs a E-prom style ecu to be attatched (one disadvantage), it datalogs (no need for a logger), can work with a maft, and programs with either a laptop or a palm device. I may be missing a few points, but that should summarize it. I'm getting one soon. That said it is just another answer, not THE answer. P.S. That was a good question.

underradar92 is correct. It brides the gap. You're no longer fooling the ecu, you're making it smarter. It's like going back in time and working with the engineers at Mitsu, and telling them that you want this size injector w/ this deadtime, you want this maf, you want to be able to log this additional input, you want to have this revlimit and you want to run nitrous, and you want antilag for track day, and you want, you want, you want... go to dsmlink.com.

The RS49T is working great for me. I've been running it since october. Spools fast(3400rpm) and pulls hard. It takes a little more to fully support a 50 trim. Good power can be made on both turbos. How much HP are you looking to make, and how much money are you looking to spend on the full setup?

So at what RPM does this turbo START spooling on your car? I am also between an Evo and 50 trim, I want good power on Pump Gas but don't want to sacrafice too much spool, like anyone else.

If it helps, I went from a regular 16G turbo to a RS49 in my 1G and it was the best mod I ever did hands down, the RS49 obviously had more lag but the top end was sick, it was way faster on pump at 20psi than my 16G was on race gas at full boost (23psi). The car went from beating mustang GT's to beating C5 corvettes. IMO, the 16G is a dead end if you're looking to make more than 300hp.

Keep in mind the rs49 and the rs49T are NOT the same. The rs49 is a agp ful garret setup ( you need the manifold to bolt it up) whereas the rs49t is a bolt on agp/turbonetics with bullseye housing.

I don't see why the Evo is getting bad mouthed so much, it has extremely quick spool up and pulls like a mofo till roughly 6K in third then it gives out. It has put down some impressive numbers, SBR claims 400+AWHP and I have seen a B16G hit 355AWHP with simple bolt ons and no internals done. With that said yes the RS49T would be better for high HP but he plans on running nitrous so I would probably save the extra $$$ and go with the Evo 16G.

 

[laza101]

I agree, I am just stating that it is MUCH easier to get more power out of the RS49T than the 16G, especially on pump gas. 350hp on a 16G may be possible, but 350hp is easy for the RS49T. Turbo spool shouldn't be issue if you use nitrous, besides, who races at 3000rpm anyway? And if you happen to run out of nitrous you can still make excellent power.

BTW I was in the same position, choosing between an EVO 16G and RS49. I went with the RS49 and it was well worth it power-wise.

If you get the 255 pump, don't forget the FPR... And I hear that 650's aren't the easiest to tune on an S-AFC...

660's aren't that easy, but it can be done. I happen to be running a 190/afpr/safc2/660 combo. The only problem I'm having right now is the aggressive timing that you get when you remove so much fuel. Once I add an chipped eprom ECU into the mix, it should be Besides, I went 110mph granny shifting into 3rd and 4th with little to no tune at all.
