Considering a turbo upgrade from stock, any ideas?

[Aznspice27]

I was thinking about upgrading my stock tiny turbo to either a evo 3 16g or a 50 trim bullseye. Im looking for around 300-400 whp. Now i have a FP 4" intake im about to purchase an APexi N1 exhaust with the N1 downpipe. Punishment racing FMIC, ACT 2600 clutch kit w/ flywheel. I have to start on my fuel system but what turbo would you recommend? I plan on purchasing a 6 bolt motor and really tweak it out over the winter but i need something now, any suggestions?

we offer some great complete packages for the kind of mods you're talking about but better yet, we can customer prepare a package to meet your exact needs. The package can include the mods, fuel and even DSMLink!

There are tons of options out there. Let me know if you want to pick my brain for some ideas ; )

i think with all the options i have im going to stick with dsmlink.... until i begin really working on my internals and such ..... for now im just going to throw on the N1 exhaust system with DownPipe and my FMIC and my FP race intake.... then im going to start purchasing my injectors/afpr/fuel pump/either FP or Evo3 Manifold/ and the evo3 turbo itself... then ill throw all that in at once and then dyno it.... thanx everyone you made my day a whole lot easier... i was about to start spending money on unnecessary mods hopefully i can have all this done by june... oh btw has anyone heard anything about the Punishment racing FMIC.... i was thinking of purchasing that...

Maybe Marti (or anyone else with firsthand experience) can speak more definitely on this one, but the issue with running 750cc injectors and an AFC is timing. The AFC works by altering the airflow the ECU sees depending on what size injectors you have, the larger the injector, the less airflow it tells the ECU about. The idea is that the ECU is programmed to pulse the injectors for a certain duration based on how much air it sees. The calculations used to determine how long the injectors are on for holds the injector size constant at 450cc (stock size), so obviously with larger injectors they should be on for less time than stock for a given airflow. The issue is that when you use injectors over a certain size, the AFC has to pull the airflow values down a lot to compensate, which in turn causes the ECU to see low airflow values and it uses a more aggressive timing map, which is bad because in reality the airflow is much, much higher than the levels that timing map was designed for, thus making the engine more prone to knock. That is why I said I would be wary of using an AFC and 750cc injectors. Now, it's possible that the NEO found some way around it or that the issue has been overblown etc etc. If you're interested in going that route I would definitely talk to ExtremePSI about that and see what they have to say.

EDIT: I see in the time it took me to write that your post just made it irrelevant haha. Just remember, you can run the EvoIII on stock injectors so long as the boost pressure is low (no more than 15psi is safe I would say) and make sure you have some tuning device when you install injectors.

i know that for those kind of power goals, a 20g and cams really does the trick..

Personally I think the evo3 exhaust manifold is a waste of money. It is internally the same as a 2g manifold but has a larger collector. Instead of spending $100+ on an e3 EM just spend $30 at your local machine shop on your exhaust manifold. After that spend the money you would have spent on the e3 exhaust manifold and spend it on an evo3 intake manifold which should effectively move your choke point from 6500rpm to about 7200rpm and put your power band into a more useable area for a medium-large turbo setup.

im going to stay away from that neo and just do it right the first time... dsmlink.... it was best said before dont rush things... i just have to find a good shop out here by nyc that does all the work and knows what theyre doing... i heard turbotrix in nj is good... but the right shop is the key...

 

[the_mork]

IMO except for tuning the "right shop" isn't that important. It really is for the most part just nuts and bolts. It is necessary to check for boost leaks after you do any major installs but beyond that it just isn't that hard. It is also my opinion that you will have a much better understanding of your car and therefore a much better setup in the long run if you take some time and learn to do all of the work yourself. Unfortunately these cars aren't forgiving enough to abuse them without extensive mechanical knowledge.

im going to practically do all the work myself then... with a help from a few others... but i def need to send it to get tuned right afterwards.... with 145K on the motor i hope it can hold up to all these mods

 

[the_mork]

Then why spend the money on ECMlink? Part of the attraction with that system is how easy it is to tune, and it is worth learning for yourself. If you're just going to pay to get it tuned then go with the harder to learn but much cheaper evo8 setup.

 

[Aznspice27]

Ok so if i was to use the evo8 ecu... is it a basic swap out of my stock ecu or do i need to account for other things?

wait before you answer that.... I plan on learning how to tune and work on my car myself trust me its something that needs to be done hands on not just go to some shop and pay them to put all the blood sweat and tears in.... no thats my job.... im just unsure of the route to take in general... it all started as a which turbo should i choose thread... now it basically has planned out all the stages of my project... and wow am i great full...

 

[the_mork]

It requires switching about 4 pins in the ecu harness, if you can poke something and pull on a wire at the same time you can do it. It took me about 3 hours to do it while I was feeling things out and quadruple checking everything, now I could probably do it in about 15 minutes.

Check through the evo8 ecu thread in the engine management section, it really is capable of everything that anything else on the market besides a full blown EMS. The evo guys have thrown a ton of tuning systems away because the support for that ecu is so great now and gets better every day.

good to know im goin to start my research on that.... maybe that might be a cheaper and better solution for my immediate goals... thanx mork
