Im kind of getting opinions like crazy on this.

A guy around my way who owns a performance shop tells me it's too much power for the street, will be too laggy, and will be a DOG until I start spooling. (reccomends t3/t4)

Another well known guy over the internet says it will maximize traction capabilities over a smaller turbo that will spool very quickly and will produce a hell of alot more power. (reccomends bigger turbo) Thinks it could possibly take bikes on the highway with ease.

I have a b18b w/ ITR transmission.
Im always at least in the 3500-5k rpm range when normal driving.
So when that bigass turbo begins to spool, my top end would be sick as ****.
BTW, My block will be fully built, top to bottom with a 9k+ redline.

In my opinion, i think a bigger turbo would be to my benefit since i will produce some *** busting torque with my LS motor. I'd rather have my tires break loose at higher rpms with momentum behind me, rather than lower rpms where i'd spin my *** off and not go anywhere at all. That's just my opinion..

So someone please give any and all detailed comments/opinions on my situation here. I'd really like to hear comments from people who actually have large turbo's and what they think on my situation.

Go big turbo with sick top end.
Or go with a smaller turbo that spools very quick.

yay or nay.

btw, My goals are 400whp daily driven on fairly low boost, tractions issues are important..(i know either way i will lose traction, but im trying to keep it at a minimal)

thanks.

 

you would have no traction issues at all due to the fact the turbo will NEVER start to spool. the t70 are what high hp supras use and even on a supra they are pretty laggy. also you will not be making alot of power even if by some mericle it did spool since they are made to push 30+psi on a 3 liter supra. that means unless you are going to run 55+psi on your honda, the turbo will be wasting ALOT of heat energy, therefor surging at all times.
for 400whp, a gerrett gt30 or precision sc44 would be just fine. there isn't much you can do about traction, short of lsd, traction bars, and sticky *** tires

i have an lsd..
and bfg drag radials for the street.
nice advice, I would take an sc63 over an sc44, though.

Sorry, I didnt mention 400whp daily driven on pump.. 550+ for track days and race gas.

Money isnt an issue

 

what do you guys think of gt35 or gt40's on honda's?

some lag is cool, but by the way the dude compared the t70 on supra's that made me think a little.

i couldnt image 55psi on the street.lol
i would dieeee..

 

whats so magic about the t70? if you want a big turbo there is alot more out there....if you even plan on daily driving it like you say your gonna get your *** handed to you by 90% of the cars on the street even if you are making 400+hp on lower boost...by the time if spools and you get traction the race will already be over...

look into the t3/t67 if you want a good tradeoff of spool and huge power

 

For a 400whp driver, get an SC61

 

That turbo is way to big for your HP goals. I would look at a SC61. Also if your not intending on running race gas all the time, your going to be running low boost, which the T70 isnt going to be in its effiency range. Your better off lookin at a SC61 ive seen them produce 400whp on 10psi on pump gas. Look for the T70 when your lookin to push 700+whp, which is definately useless power for the street, and even the track.

check that turbo

You really need to configure a turbo to meet your 400whp goal. Unlike the VTEC motors, LS motors don't need the same size turbo to make the same power as the VTEC. Honestly, a 60 trim T3/T04B would do a helluva lot more than you think. You don't neccessarily need to have such a large turbo to make power. Very common misconception

 

or what about the gt28rs... its got extremely nice spool all around.. my friend has it on his gsr..

 

Fulll T4 Turbos are for 600whp+ Cars.

Agreed. They use a lot nitrous to spool that damn turbo. It's too freaking huge.

No they don't...a Supra can spool a T-70 fine.

I know a supra can but nitrous is used to spool the turbo quicker. A lot of drag cars use nitrous to spool their turbos

 

No they don't...not for a T-70. If they are using Nitrous, its for more power.

I know what I'm talking about.

What are you talking about, NOBODY uses T70's on supras because they surge like ****. If they surge like **** on supras at low boost, I can see them surging like **** on hondas, even at moderate boost.

IF you want 400 on pump gas and 550+ for race gas, run a T3/T67 or a straight up PT67.

 

500-550whp - SC61\GT35E

600+ - PT67 Q-Trim

 

why does everyone recomend a damn sc62 when it is in its peak range while pushind 29psi on a gsr and 26psi on a b18b? with boost like that you shoule be making well over 550whp.
i ahve seen about 5 setups that people had the sc62 were it was actully doing what it was ment to do.
sc62=honda tech bandwagon at its greatest

I'm going to assume you meant SC61 in this case, and i'm also going to call you a fool. People are making 400+ WHP with low boost from SC61's. They spool nice, are cheap, and make great power. Do you call T3/60-1's a honda-tech bandwagon, because a ton of people were running them? How about full-race manifolds, or hondata, because a ton of people run them too? SC61's arn't a bandwagon, they're proving to be great performance turbos. The only bandwagon I see is saying that the SC61 is a bandwagon, because more and more people are jumping on that.

Yes, those are bandwagons.
