It's not worth it when a T3/T67 can support 650+ WHP with much quicker spool.

reason i asked is because i have one sitting at the shop, thinking about using it

TURBO DC2

im curious as well

I personally think it would be fine to run a T4 on a street car. I mean you most likely would not hit full boost until 4-5000 rpm's but it would be crazy when you do. Also just for driving around everyday....you shouldn't really ever be going over 4000 rpm's anyway so I think it would be perfect. You could pretty much stay out of boost until you wanted to.

from what i've researched and got from a few fellow h-t'ers is the the .58exh p-trim of the T4 family, is comparable to the .63exh of the T3. i was also told the spool of a T4 60-1 w/a .58exh would spool somewhat comparable to between a .63 and a .82 of the T3 family.

a good guy to ask is bryson, he runs the PT-61 w/a .58 and i believe he said he gets full spool at 5k rpm w/a 2.0L gsr.hth

on my old setup on 81.5mm bore i had a t3/t4 .57 trim and .63 ar... it hit full boost around 4300-4500

Then i was using a turbonetics T4, not sure what size but it was huge... Hit full boost close to or about 5k rpm. Pretty laggy but i don't mind.

Comparing those 2 turbos when i was using the t3/t4 i would break loose in 2nd gear badly everytime, but with the t4 i didnt break traction that bad because it spooled up later. T4 is koo but don't get a huge one though. Get a small T4 or go with a t3/t67, Thats what im about to use now and we'll see how that'll do

I was about to say ask Bryson. Ive been in brysons car, it spools faster then my 60trim on my ZC. There is hardly any lag.

Ive also been in Bucks (GT40 i believe) and Cortney Green (pt71gtq) and both their cars spool around 5800rpms with a wicked topend. Both of them drive daily its not really as laggy as you expect. Cort put down 802whp, Buck did 519whp on pump gas. Both have crazy numbers. Super fast cars.

If i had a healthy built 2litre b-series id rock a t4.

sounds like the right price Get-R-Dun

I workd on a guy's LS, built (stock bore, stock LS head and IM etc..) with a T4/60-1, 3" turbo back etc..

Laggy is an understatement to say the least, but boy oh boy when that thing hit.. whoa!! It was good enough to keep the turbo on boil even between shifts, but IMO it's still too laggy for a street car.

mrDFWmechanic

i have a friend with a T4 in a fully built R and man when that thing spools up its gone thats all i can say

I don't understand the concept of wanting a big T4 on a B-series motor at all when you can run something even as "small" as a T3-flanged GT35R and be seeing tons of boost at 4500 RPM's. I'll take that 1500 RPM's extra powerband, and still have a turbo with well over 600 WHP potential, thank you kindly. What is the point of running a T4 turbo when T3's are proven to support over 600 WHP, more than almost every single person in this thread will ever make in a honda.

The Tea-father

the turbo is a hks t04e, 57 trim and a .63ar, the smallest T4

some people dont like pushing the turbo to the limits and personal preference. Don't need to boost as much psi with a bigger turbo

ITR206 made 450 WHP on pump gas with a T3/T67. Espanol made 470~ish on pump gas with a GT35R. Jordo made over 500 on pump gas with a T3/T67. I made over 450 on pump gas with a T3/T67. That car boosted hybrid just tuned made 450 WHp on pump gas with a T3/60-1! All those turbos are capable of pushing you into the 9's. I don't buy the "don't want to push the turbo as hard" load of crap when people are making such absurd power even on pump gas with T3 turbos.

I have a pt-61 with s-cover i will be running in my street car. My kit isn't fully completed yet so i wouldn't be able to tell you what spool up is like.

Its is worth it when the t4 version is much more efficient.

I run a full t4 on my street car, when it comes down to it with the same turbo, some configurations are much better than others.
The t4 option on my setup is actually supposed to spool quicker than the t3 equil....

legendboy

Also too it really depends on how you want the car to respond. I have run 3 different turbos. 60 trim T3, t3 60-1 and a 50 trim t3/t4. This year i am running a straight T04E 54 trim with 76 trim exhaust and a .58 housing. I plan on it spooling the same as a stageIII .63 T3 setup but when the boost hits with the T4 watch out That thing will breathe like a champ up top compared to any T3



and also, why not!?

Who cares if it's "much more efficient" when the T3 version will get it done, put your car into the 9's, and do 450+ WHP on pump gas without a problem? I've drive a straight T4 T67 car, and all that lag wasn't worth squat on the top end. Tell me, why does being a bit more efficient matter when the T3 frame turbo will make all the power you want and spool quicker?

because apparently you are ill informed.
Did you even read what i wrote?
last time I checked any of the t67 variants wether it be full-race/garret/pte the t4 versions are good for more power FYI.
Call up pte, they will straight up tell you to run a t4 over their t3 on t67 turbo all day. A T3 obvioulsy does the job for the turbo, but the logic is completly retarded.
A 67mm compressor is too big for a t3 regardless of what turbo it is.

h22 civic

pt67 with 88mm wheel i hit full boost bout 4800rpm on a 2.4 h22

ATgrills.com

My T4 super70 does me just find,,, boost at about 5K... and put down 479WHP with my little 1.6L

Suprdave

T4 will let you carry your power out past 9k...try doing that with a T3.

I'll be running a t4 on my 2 liter b20/vtec

I think for smaller motors, a t4 would be pretty laggy. but for 1.9 liters and up they can perform pretty well.

The Tea-father

this is the same turbo i have . a T04e 57trim, my motor is a sleeved 83mm with 9 to 1 cpr. Hopefully the 83mm will help it spool a little quicker
