Hey Ludi, long time no see/hear! Stock block, or stock bore stroker? I know you are going to say, "It will run out of breath" too fast! But it will be a hell of a ride till it does. I wanted to go down a "path less traveled", and get the "green". I guess it is most popular now, as the waiting lines/results prove are proving that. I will abuse this setup on autox/drag/road courses, and report back how it performs. Weather that be good or bad, I am about to find out. I think this is what I want for the applications I am looking to use it in. Fastest off the light ('60 ft) light to light (Mexico only), fastest out of the corners/turns in autox and road courses. I am looking for that "extra blip" on the gas which will get me out of the corners faster, while the larger turbo's are spooling up. Not sure, but I think this is the ideal setup for me. Not really looking for that Hi-end rush, while trying to race a hyabusa at 180MPH on a crowded highway. I don't do that, nor want that. The MORE HP, the more wear on the other parts, and the more a larger turbo could end up costing me in the long run. If I can get in the mid-low 11's, and do well on the drags (Rarely do them), road course (putnam Park) and autox's..........Mission accomplished for me. A true test would be at WWIV next year, where there will be LOTS of evos with all kinds of turbo/cam/shop setups, and we can see how it performs doing various tasks. Will be interesting.

 

Hey Smoked, if you're around, maybe I'll swing by during the F1 USGP in Indy next month.

My opinion for good turbo/engine matches for street/road-racing use are:

1.) stock 2.0L, stock internals = FP Green
2.) built 2.0L (forged internals, upgraded valvetrain, etc.) = 50 trim, possibly 3076
3.) 2.3L = GT35R

Pros/cons of each setup:
1.) CHEAP!!, nice torque curve, slightly later than stock spool, still falls off up top, though not as bad as stock. Powerband is approximately from 3500 RPM to 7500 RPM.
2.) $$$!!, spools around 500-700 RPM later than stock, flat torque curve, will support shift points of ~8500 RPM on pump gas. Powerband is approximately from 4000 RPM to 8500 RPM
3.) $$$$$$!!, spools close to stock (maybe 200-300 RPM later?), stock like torque curve, but at a much higher level. Powerband is approximately from 3500 to 7500 RPM (largely determined by which 2.3L kit you got, some dont' rev any higher).

The only dark horse out there right now is a twin-scroll 3076 setup. I've only seen one car setup this way, so there's not enough data to support the theory, but theoretically a twin scroll 3076 should spool as much as 500 RPM earlier than a regular 3076, without losing any topend.

Thanks for the advice (as always) Ludi!!! You know where I live, let me know when you will be coming down. I will see if I can get some VIP passes or something down at the track.

 

Lud - more details on this dark horse twin scroll setup, please?

 

I wish I had more details. All I know is that Full-Race is building them and Drifto has a custom twin-scroll setup on his Evo. Claims have been made that a twin-scroll 3076 will spool 500 RPM earlier. IMO the theory is sound, but there just isn't enough data yet for me to call it fact.

Still on waiting list...........and waiting. Just thought I would update you. Old turbo is off the car now, ready for the "Green". I am wondering about the engine management. Stock ECU? Or maybe the MAF-T? I DON'T want to spend the money for a stand alone, so we will see what we can get out of a comparison between the Stock ECU and the MAF-T setups. Till then, I have to do something to keep me occupied, like Donald here:

 

Awesome write up man! I was wondering if anyone has done a Built 2.0 Rev to 9.5k with a 20g? I think that would be pretty cool.

 

imo a 2.3l is too much for a 20g...thats just my opinion. it seems like it wouldnt really feel like a turbo car...more like VTEC feeling. my buddy has a 37R on a 2.0l and it feels fine on the street to me...i think it would be perfect with a 2.2l so he can keep some revs. idk... i read the whole write up so i see what you are looking for and it seems you are firm on it....

im gonna suggest anyway...i would run a GT3076 with the 2.3 i think that is a great combo.

great write up tho and have fun with it...whatever you do

 

I appreciate the input. I will see how this turbo does, and will compare it to some GT3076's, in as much as 60ft times, 1/4 mile, and see how it stacks up with "Other" turboed cars at road course tracks as well. If the difference between the two in real world applications is that great............who knows, might have to change again. Time will tell. I think all my "Business" will be done BEFORE this runs out of breath. Just my opinion. I will have the paper trail to back up if it is true or not. I want some light to light domination for the vette/viper that pulls up against me (while vacationing in Mexico of course ) I think this combo is the right one for that.

 

Tune it with the stock ECU.

Thanks Ludi, will do.

 

........As I love the way the car feels, even "Untuned" on my TME16G, I will surely love the 20G as well. I just wonder, HOW MUCH HP I could expect to gain with just the turbo swap, and a good tune? Any ideas?

 

From what I hear it's about 20 peak HP shy of a 50 trim...if that helps.

I'm going with the green as well...for the same reasons! Good luck with everything, and it's awesome that you work with the kids!

 

With the 20glt, your car will be very boost happy. But it might run out of steam on the top end.

 

Thanks guys for the props and words of encouragement. I think this setup would be unstoppable up till it runs out of breath .........I will keep you posted. I don't want to run with any busa's with this setup.
