any input is helpful....

ok WHEN UTEC comes out....
I am goin to buy either garret gt30 or aps sr50 turbo
Also goin to be looking at c02 on nitro sprayer for intercooler and intake
I WANT TO STAY TMIC.... BUT IF I CANT il go to fmic.. last resort

so

my ? is what turbo should i go with and why? what should i use to cool ntake fuel and intercooler c02 or nitrous ? and why? and y cant i use tmic with either of these turbos at high boost? want to keep it stockish looking!

go on with ur bad selves guys! post info

Some good questions - I will be watching this post. You know you will need injectors too right? What kind are you considering? The P.E.'s look like an obvious solution but I read they are slower than stock, heard anything good about the perrin?

What is your power goal?

[maxwolfinger]

and what do you want, a drag setup, a street setup, an autox setup? Also, the stealth black FMICs from APS are kinda inconspicuous.

11.o sec quarter is my goal .. and yes i know i wil need internals as well as injectors and bigger fuel pressure reglator and fuel pump.

Have you thought about water injection?

http://www.aquamist.co.uk

Seems like a great way to keep things cool and prevent detonation at the same time.

[doublej]

ya i have thought about it.

[crashsti]

water injection? are you talking about the system where water is injected into the combustion chamber to keep things cool? you have to be kidding? while yes water injection works, it does'nt really address the reasons that you may be getting detonation under a high horsepower situation. think about it, does injecting water into an engine seem like a good idea? i don't care how far the technology might have come. better off spending you money on something else.

Please review and read up on the technology before you bash this idea. Its an excellent idea (in addition to tuning) and one that can provide safety and reliability to your engine. Also for the price, its been argued its more effective (bang for buck) than an intercooler... what else are you going to spend your money on?

It doesnt seem like you've researched this alot and posting a negetive comment about something that has been used in racing and other applications doesnt come off as a good contribution to an automotive forum.

For those interested Water Injection is a good cheap way of keeping your engine together and a very safe and easy mod (cheap also) that has been used from the Airforce to F1 racing and *GASP* RALLY CARS and has been around for YEARS.

One quick link:

Read the link for information. If your sceptical, then say that you are, but please dont advise against tuning aids if your unsure of their use and or effectiveness. IMO thats not a contribution to an automotive site.

well i know what i want so keep posting.

SR50 - 1bar flows 37 lbs/min at 75% eff. Plenty of flow even for 2.5L STI.. But, you will notice the lag. You will probably see 1 bar at 4300 RPM given the fact that it has even larger than compressor wheels than SR40.

[rallybred]

you have to be kidding?

actually the WRC car ours was modeled after is water injected.

[crashsti]

i knew i would catch some flak, which is Ok. my point is, what is good for a racecar does'nt always translate well into a street application. there are plenty of ways to build an over the top engine combination without resorting to the "novelty" technologies. sure, nitromethane is good for racing, but does that mean its good for the street? it would be wicked, but no. its my understanding that water injection helps prevent overheating in race applications or poorly thought out street applications. too much compression or older cylinder head designs tend to be the main culprits. perhaps i was a little out of line with my "you have to be kidding?" statement but i stand by my beliefs. there are dozens of others aspects of an engine that can be tuned and modified before looking into water injection. it does make sense to use it in an all out competition situation such as WRC, but i am certain that it is'nt the first technology the teams look into when they want more power. sorry for hi-jacking your thread doublej.

You're slightly misunderstanding the uses for it though. Certainly it could be a safety for a tuner who isn't capable of properly tuning a car, but it's very useful for a good tuner as well.

Water injection is one of the most exciting technologies I've seen that you can impliment for building power. It lowers the flash point of the fuel - effectively the same as increasing octane, and preventing knock. So you can run higher boost and higher compression without needing extremely high octane fuel. Even a perfectly tuned car could see obvious benefits from adding water injection. It's not for mistuned cars.

If you tuned the maximum possible power from an engine without getting knock, you could add water injection, increase boost, and gain even more power. Or, you could use an ECU map for higher octane fuel while running pump gas.

Water injection is great stuff, and if you use it instead of buying race fuel, it pays for itself. Water is certainly cheaper than taluoine (sp?).

For those that dont know, WI sprays a FINE mist into your intake stream, that mist is converted to STEAM by the temp of your cylinders and the air, its that conversion that takes away large amounts of heat (the faq's have information on the actual amount but its a LARGE amount) thus lowering your intake temp (like an intercooler) and cooling off your cylinders (isnt that a GOOD thing? correct me if i'm wrong ) and the steam simply escapes out of the exhaust.
Also this is pressure activated so it only (typically) comes on at a prediscribed boost setting, its like nos but instead of nitrous you use water.
Look it up, its amazing, cheap and VERY efficient. I've read about Grand Nationals that run on ONLY water injection no Intercooler, THAT is impressive

FYI my TD06 was a 20g turbo, I ran, like most, 15psi for daily driving (around 250rwhp) Others that ran water injection increased boost up to a daily 19 psi with NO detonation compared to some like me that just used an IC at the time. 19psi was good for over 300rwhp, on a daily car w/ no knock... nice
