Setup:
sleeved b16 8:1 c/r
built head, CTR cams, JG intake.
LS tranny(long story)
Sc61. .63 a/r
94 EX coupe, full weight

Ok Im running 15 lbs right now. and in 3rd on the highway I cant ask for more at all, the car pulls hard. but 1st and second are completely weak. raced an Ls1 camaro from 20mph, and couldnt blow past him till 3rd, same story with an Srt-4 with a stock turbo on more boost. the car is *** rape from 3rd and up, but below its just nothing.

Right now I dont spool till about 4300.I dont see 15 lbs till around 6k. I need a turbo that can get going from 3k and hold power till 9500. someone locally recommended an 25g with a 8cm back housing. but I cant find that turbo anywhere online. is there something in the Precision family that will help?

sounds like my turbo would be right up your alley t3/to4e 60 trim. It spools very quickly and does not run out of breath up top...although my motor is a 1.8L, it would definitely be a bit laggier on a 1.6

how about a disco potato?

 

The 28rs will not make power till 9500.

Being you said you wanted quicker response, definently look into the GT series, what kind of power are you looking for? I really enjoy my GT3076R .82 a/r on my B18C1.

I really dont know what power I want to make, I dont care about peak hp at all anymore. I want the car to pull much earlier than it does now and still have enough top end to trap mid 120's or better. I want the broadest powerband possible and still trap 125+

Are you sure about that? He's only running a 1.6 litre, look at guys who are running the GT28RS and you'll see that it is more then capable of making power up to 9500RPM, a prime example of this would be Tony The Tiger's Integra.

 

3071R or 3076R... couldnt agree more

 

Here is a td06-20g its rated at 400+hp and spools incredible fast. but I still cant find the 25g anywhere http://www.dsmparts.com/custom...age=1

 

I want a garret gt2871r or the gt2876r for my h22. I currently have an 18g and I love it for a street turbo, really quick spool ! I dont like the fact that it runs out of gas up top.

 

Greddy makes the T67(25g) turbo. Maybe this is what youre looking for? I think it is kind of pricey.

 

i have a gt2871r on a stock b16 .86AR full spool does not happen till over 5000 rpm but it starts around 3500, feels fun on the street. if i was to do it again i would have got the smaller turbin housing

There's quite a few differences in Tony's setup vs. what the original post stated. Don't get me wrong, the 28rs is a great-street turbo, I kind of miss mine a bit, but for a Honda it's really all mid-range. The thread-stater is kind of asking for the best of both worlds...really quick spool with top end

 

Yeah this is very hard to have the both of both worlds i guess. Quick spool and top end. Thats what i dont like about the 18g no top end at all.

 

The biggest problem is your engine is built for making tons of power on gasoline. Now you are saying you want a street monster. Which one is it? If you want a street monster, you need to raise your compression ratio up and get a shorter geared transmission. Once you get that compression ratio up your best turbo options would probably be a GT28rs, GT2817r, or GT2540r.

The GT28RS is going to be a tad undersized; it will still make power up to 9000RPM, but that's not the case. It will only make up to about 300-320 WHP and that's it. I am afraid you will begin to dislike the turbo because 3rd gear will be noticeable weaker than the SC61.

My best suggestion is a GT30R... Whatever trim you choose is good, just don't go with too large of a turbo for your specific power goals. The GT30R is going to be a significant improvement over the SC61 no doubt.

 

get the 30R

the 2871 R i had MAJOR Problems tryin to get traction /. very difficult

 

I have a t3/t4 with a .48 hot side and .5 compressor with an upgraded wheel. I hit 7lbs by 3500 and Oh man is it beautiful. I might be going for somthing a little bigger though I want to hit 400+whp when the time comes

Exactly what's gonna be on my stock GSR soon.

 

Tony I know the technology of the Gt30R is better than the sc61, but I just cant shake the feeling that I would still not be happy with the response of it. I been doing some research on DSM turbos. and they all seem to be so small but support massive hp. and able to sustain 22psi+ boost levels for long periods of time. but anyway, wouldnt a t04e .60 trim offer significantly more 3fd gear pull than a 28rs?

 

I love my sc61, I never lost, except for when I race my boy who also has one, response is really great, instant spool as soon as I floor it, spin tires from 1st to 3rd 4th gear murderer, 5th gear top end autobahn beast. ls/vtec 9.5.1 compression built head, crower cams. stock sleeves, rev to 8600rpm. I would never get a GT series turbo, overrated in my opinion, if I upgrade it would be another regular bearing turbo.

 

In my opinion get rid of that crappy ls tranny i have a friend that had a b16 witha sc61 it dynoed 295 whp on ls tranny i drove the car it was weak *** **** till 3rd we took it to the track it ran low 14s on street tires we swaped the tranny to a b16 trans and the car went 13.2 on street tires. I personally had a stock motor b16 witha sc61 my car went 12.3 @116 and dynoed 315 whp and i never had any problem with ls-1's or srt-4's unless the were heavliy modded

Tranny stays I hate being in vtec just to take a damn trip down to Miami. I had the b16 tranny and wont go back. with the proper turbo the Long gears wont be noticeable.

what engine managment do you have? you can take care of the vtec problem easily. the lower gears you dont notice much differnce with the ls vs b16/gsr, its 3rd and 4th gears that feel like turds with the ls trans.

i think a gt30r would be the answer to the question here. honestly, with an sc61 on the car........ its either spinning or driver error thats causing the car to not move anywhere in first and 2nd gear........its surely isnt a "lag" problem.
