Im thinkin on going all out motor on my 01 gsr. I have been reasearching and i dont know if i should turbo it or keep it naturally aspirated. what should i do?

 

Well. If you want to get big power from the engine you'll need to build it anyway, so it's something to consider.

If you just want to get a few more horses you can bolt on a turbo and do all the other tuning for a lot cheaper.

 

What's your budget and how much hp do you want to make.

 

That's the big question right there.

NA will cost you, but you can make big gains from it. Boost will also cost you, but at least you are only spending to a certain extent. If you just slap on a turbo (kit) w/ stock internals, head, etc. you will make a good amount of power. However, if you put that turbo on w/ a built motor, your talking about a nice increase in power.

The sky is the limit if you have the funds.

 

everytime i go to a shop i ask that Q? 50% is keep it all motor 35% is put a superchager its more reliable than turbo plus less of a chace that it will mess up ur engine 15% turbo i wouldnt use turbo

 

What are you talking about?

 

Answer these questions and I'll advise you based on your answers:

1) Is smog legality a concern?
Does your state require an emissions inspection every two years?
What state do you live in?

2) How reliable do you need this car to be?
Is it your daily driver or a weekend toy?

3) What's your priority?
Straight-line speed & highway dominance?
Mountain road & autocross superiority?

4) What's your budget?
[Remember the adage: Cheap, Fast, Reliable: Choose 2, you cannot have all three.]

If you're in a emission-controlled state and favor outright grunt over grip, I'd advise turbocharging your GSR with the GReddy bolt-on turbo kit. At least two other forum regulars run this kit at this time. For about $3500 or so, you'll have about 210-240 wheel horsepower, enough to get into the mid 13's on street tires and pump gas.

[Däs Schmoo is our resident authority on that kit - and turbocharging in general ].

The problem I see with a high-hp [230whp+] N/A build is that you're going to run into a wall of diminishing returns very quickly, particularly if you live in a state like California, which follows the CARB Exemption Order Guidlines.

Under these guidelines, only CARB-approved parts can be fitted to an emission-controlled car. If there isn't a CARB EO# for the aftermarket manifold, cams, cam gears, exhaust header, catalytic convertor or injectors, etc.. they are de facto illegal modifications and you'll fail the visual inspection before even seeing the emissions test.

Yes, it's utter bullshit... but it's the law. Unless you want to pay twice the going rate for a fraudulent smog check every two years, it's quite difficult to run a built N/A motor legally in a state like CA.

 

-Overall im going to spend at least 5k to 10k on this car.

-I do live in california.

-I like drag and track.

-Its going to be a daily driver.

Thanx for all the help.

 

Then, the Greddy kit is for you...assuming you don't have a smog place that will pass it with illegal parts on there. I have seen some good gains out of the Greddy kit with some basic bolt-ons, larger downpipe and a better method of tuning.

 

i have an 01 turbo gsr, and i went through my n/a phase, now i can't understand why i even went down that route of n/a...
