I have descent lag. If I race from a roll I just brake spool it. Its a little hard on everything but its pretty sweet to have full boost on that last beep. Takes off like a rocket. Im waiting to see how this works out for Andy....hint,hint. haha

Rep Power: 0 [QUOTE=andyman97;4063847]. I plan on about maybe 18 psi daily and around 25 on face fuel. I figure I should see full boost at around 5-5200 rpm with this turbo.
[QUOTE]
wow, look at andy go...400 shouldnt be a prob with that turbo...we both know that i was making well over 400 with it on my car...good luck man...although i dont think it will take that much boost for you to make it...

Rep Power: 0 Just curious as to why you chose the 3076 over the 3071. The 71R will spool up a couple hundred Rpms faster and a have a better transient reponse between shifts. Its power level is just under 500whp maxed. You've stated your goal was only 400whp. A couple hundred rpms is a huge difference between closely matched cars.

Rep Power: 326 Couple of reasons.
For one, the turbo you're talking about is only available in a 5-bolt internally gated configuration.
Two, I'm going to need every bit of power I can get. These turbo's horsepower outputs are rated on 2.0-3.0 engines. What it makes on mine is not what it will make on a 2.5 dohc.
Just because it will make "more" power does not mean it will spool up slower and with the exhaust housing I am going with, it will actually spool faster than the other two gt30's. Turbine housings are .64 and .81. Even bigger than the one I am going to run.

Rep Power: 0 I don't use the .64 or .81 GT housing. I personally don't like them. You can get a 3071R in any configuration you want you just have to look harder. You can use a T31 4 bolt housing to keep your external gate and make great power out of a .63 housing. Anything smaller will cause unwanted surging.
A turbo will flow a given number of CFM regardless of engine size so really what you want is a over better power band than just peak numbers.
You want to look more at the wheels your using. The GT30 compressor is top notch.
Edit: The 76 will spool slower than the 71 because it requires more energy to turn the wheel all else being equal.

Rep Power: 373 Larger turbine housing=slower spool time. I am sure if I was willing to pay a ton more I could get whatever configuration I wanted. As far as cfm, yeah, that's what the turbo is capable of but the less amount of output from the exhaust, the longer the spool time. This thing will spool a hell of a lot faster on a gsr motor than with a d17.
Wish I had a Turbo

Rep Power: 373 A turbo that would spool up faster and something that was built with your power range in mind, not something made for 100 more hp then you're looking for.

Rep Power: 326 Once again, these turbos are rated on 2.0 to 3.0 litre motors, not 1.7's. What it will make on a gsr is not what it will make on my engine. I am not going to limit my ability to make power by the turbo....

Rep Power: 234 yo spoolin u never have anything good 2 say so why even talk? anyone can go buy a LS teggie and throw a turbo kit on and make 350-450whp, or just about any DOHC it is easyer and they can handle more power. good **** andy cant w8 2 see the beat come alive

Rep Power: 326 Yeah, my engine is an ex. I made 195 whp on 6 psi with a full lx motor....so yeah, 200 whp is very easily attainable. But why not go with an ex head?

Both have the T3 flange for your manifold. Ton of money??? I think not.
The place I get my turbos from sells them in any configuration I want without extra $$$. The .71 will spool faster because the wheel mates up to the tongue area perfectly and mated with a GT30 compressor wheel you'll be making close to that 500whp goal.
IN all seriousness if you can get 500 out of that engine with the proper set-up it should hit low 10's with a 130-135 trap.

Rep Power: 262 lx also has dif. gear ratios which are said to be better for a turbo set up then the ex gears. and why would 15 hp make a dif. when thats NA when its going to be turbo....

Rep Power: 288 and the ex has higher compression....so if youre going turbo, the lx head is a little better to boost with, granted there arent really any parts for it. And the ex MAYBE has 10 more hp....and its pointless, unless you want the ex head in order to put on cams, valves, etc for an NA setup.

Rep Power: 258 With all do respect do gear ratios really matter when it comes to LX vs EX. I mean its not like the EX has gears like the S2000 which is super short. I know ppl say the same thing about boosting an RSX type S vs the base rsx because of the gears but a boosted rsx type S is still a beast. And while we're on the subject of gear ratios what about the higher redline of an EX vs the LX. Can you make the argument that the EX is better to boost bc you can actually take it to 7200 rpms? What about the higher compression of an EX vs LX. Same argument a GSR is still going to be a beast turboed vs. an LS VTEC. My point is that these differences shouldn't be much of an issue; it all comes down to the tune IMO. You'd be tuning a LX differently from an EX but should still make similar amounts of power at the end of the day.

IMO, ANY d17 is just a waste of money. If youre gonna spend that much, just do a swap. The d17 was never built to be a "performance" motor or to handle the stress loads of big turbos.

Rep Power: 326 Well, I just got my intake manifold back today. There were small cracks in the runners due to stress. I sent it back to JDM Fabtech and Gerry rewelded the runners and put some heavy duty support brackets on. Can you say 18 psi at 4300 rpm?
