Noob Turbo questions

[DropBusa]

Okay, as the title says i've got some noobish questions about stage 1's. I'm sure the answers are to be found on search but i've got a FEW questions.
1. If i want to run just a stage 1 at low boost (no more than 7lbs) do i need to concern my self with a fuel regulator? (05 busa)
2. Do i need to concern my self with a water/meth injection system for the same setup?
3. As it being a daily driver do i need to look into a second fan or maybe a water wetter mix?
4. Stock engine safe to run for low boost setup? (i've heard "dont get greedy!!") Or do i need to concern myself with spacers, pistons and rods?
and finnaly 5. If i chose to go with RCC or Velocity. Do both of these kits include ALL the neccesary pieces/parts or do i need to expect hidden costs.

I've read "around the bush" answers to most of these questions, but i'm lookin to ask them myself and get them answered from the pros.
thanks ahead for the help.

1.yes
2.no
3.should be fine stock, water wetter is cheap,add it.
4.no, stock engine will work fine for 7 pds
5.everthing included, only extras to upgrade.

so to follow on then.. School me on the fuel reg. I thought i read somewhere that i only need it for heavy stage 1's. 10 lbs or more or stage 2's

You need to use the rising rate regulator that comes with the stage 1 kits. I recommend the RCC kit also.

[thepushercg]

you need to regulate the fuel with a fmu to keep the fuel pressure level at all times. go to

There's always little extra things your gonna have to buy.  Make sure to get a system with an external wastegate dump pipe. It makes tuning your kit much much easier.   I mention this since alot of entry level stage1's come standard with the boost internally wastgated.  Internally gated turbo's alot of times suffer from boost creep because the turbo can't properly exhaust the unused boost properly. Boost creep is when the wastegate does not vent enough and your engine takes in more lbs of air than needed. That can cause a severe lean condition and make the engine build lots of heat and/or blow head gaskets. Spend the couple hundred extra and get the external.

Then, probably the most important.. Find a tuner that knows turbo's good and know's how to properly tune them. Not every certified Dynojet tuner can do this. You need to search around.

Correct to all of the above. As Pinky has stated many times,a stock stage 1 setup as described is good for short WOT runs. If you start pushing it you will get bit. Do not go out and try to set a land speed record with this setup.

Yes, I aggree, don't top her out, bad things happen, just ask me.

[fat&slow]

yes listen to these guys they are correct. go with an rcc, i have a velocity.

I am considering doing a stage 1 turbo on a gen1 bike but this concerns me. Could either of you explain why an otherwise stock bike with a stage 1 turbo setup installed would not last long? I'm getting conflicting reports and just want to get the whole story so to speak. I'll be honest and say I'm not real familier yet with turbo's but is part of the problem due to insufficient intercooling?

there are a few factors in fried motors
1 poor/improper fueling
2 fmu's arent very reliable (failures can happen)
3 charge temps
4 compression ratio

any of these can lead to detonation which equals fried motor if it gets bad enough

I blew a head gasket on my stage 1 first time I got to 170 mph.

The fuel pressure regulators are important on systems as boost goes up.. (long version)

there is a balance that needs to be met as more boost equals less effective fuel pressure... (part one of a double whammy)

say you have 10 lbs of boost and 90lbs of fuel pressure.. you now have an effective fuel pressure of 80 psi and fuel flow will reflect the "loss" of the 10lbs of fuel pressure (injector is now pushing against 10lbs of back pressure instead of a vacuum). So you effectively loose a % of fuel flow and you also have more demand for fuel due to air density.. (part 2 of the double whammy)

We used to install what was called an "S" valve on the first FI systems (mechanical) to help compensate for this loss.

This is where a good tuner comes in, they can usually get enough extra pulse width to make up for the loss of fuel pressure and then a bit more to help keep the motor safe and making good power..
