current setup

b16 block
gsr head
arp headstuds
inline pro 3 layer headgasket
Victor X Intake manifold ( i think its too big) give me your opinion
Drag 3 kit
t3/t4 turbo ( dont know the tirm but its new with the blue plate on it)
turbonetics wastegate 7psi
hks bov
drag manifold
drag DP 2.5 inches?
testpipe 2.5 inches
greddy evo exhaust 2.5 inches 3 years old lol

car made 277whp and 187tq at 12psi

Current driving conditions: i have no leaks but it sounds like i do, i even had my mechanic did the smoke test on it and i had no leaks. boost builds slowly. full boost by 6000rpm or so and it starts building boost by 2500 rpm too and i hit about 5 psi by 5000 rpm.

What i want it to drive like: i want the boost to build alot faster for the street so it can be a daily driver and no have to make torque right before i shift. What can i do to get more low end and midrange power? is the IM too big for my setup? i remember the GSR IM being very good before i blew my old motor up. any help is appreciated / wanted. THANKS

Wth you fully boost 12 psi at 6000 rpm? Either you have a leak or your turbo just plain too big...

 

What is the "smoke test" you are referring to?

The turbos that ussually come with drag kits are pretty small. My brothers old Drag3 GSR spooled a lot faster than my sohc does now. I believe the GSR kit comes with the 57trim .48. Im not sure what application the kit you bought was specified for.

Dont just have someone convince you to buy a new turbo either. I'd almost be willing to bet there is something screwed up with your setup if you are actually running a turbo from a drag kit and you cant hit 12psi before 6000. My SOHC with a bigger turbo than yours spooled 17.5psi around 5500 rpm just for comparison sake.

 

sounds like u already know what u need to do. Go to a smaller turbo...

 

my tuner said my turbo isnt too big. i had an old t3/t4 and my buddy bought the whole turbonetics kit for his prelude and his turbo was too slow for his app. so i bought the turbo off him cuase mine was 3 years old. and it still performs the way it did before i changed the turbo. my old setup was the same turbo and gsr block and head completely stock with gsr IM. now i have 1.6 block and 1.8 head with thicker headgasket. could my compression be too low ? i dont know if i want to change the turbo again. any other help or questions to get farther with this? it still made 277whp on 12 psi it just spools slow.

BTW: smoke test is where you have a machine that blows smoke through everything to find a leak and i had no leaks

 

Ever tune it after the turbo change?

 

you should try to find the actual size of the t3/t4. is it a B or E housing? and trim and a/r would be needed also.

 

i heard its the same turbo. im not writing this becuase it just recently felt slow to spool. nothing changed after i changed the turbo. its just that in general it feels slow to spool. my tuner even agrees so i started out by getting a new wastegate cause all my parts were 3 years old. my thought was to get a neukin manifold and 3 inch DP and thermal exhaust but im wondering if even that will solve my problem. i just want it to spool very fast and be streetable. maybe a smaller turbo is my only option but i dont know yet.

 

You really think the turbo he just bought off ebay is the exact same trim, a/r, and wheel as the one you purchased 3 years ago?

Different turbo -> Different tune

 

gt28rs!

His setup obviously has something funky going on if it makes 12 psi of boost from a small T3/TO4 turbo at 6K, but you're right, try and bandaid it with a smaller turbo

I didn't say it would fix any issue. He wanted to know what would make his car a better daily driver.

I used to have a t3/t4 and it sucked on my b16. I have a gt28rs now and it's way, way better all around. Once you go ball bearing, you won't go back!

BTW my t3/t4 spooled at like 5000-5500rpms on my stock b16 with a restrictive (yet silent) RS*R catback and 2.5 inch downpipe.

 

okay everyone, i was working on my car today and decided to run open DP on the way to the hardware store to get some new bolts to fit my catalytic converter on for emissions.

VERDICT: running open DP: sounds louder, doesnt really spool much faster , sounds very intimidating though. got alot of looks lol

current turbo builds boost at 2500 but still is slow to make boost. got 4psi by 5000 rpm and finally hit 10 psi by 6200 with OPEN DP. so does this mean my turbo is tooo big for my setup? i think it is now even though everyone says it isnt. do you think the jg manifold is too big cuase i heard its the best manifold for turbo or is that just drag racing. i really just want a streetable car with quick boost. ill sacrice topend for low end and midrange what is the best bet? thanks

 

also i was wondering if maybe my compression is just too low now compared to when i had a full gsr engine. cuase now i have a b16 block and gsr head which i think allready lowers compression, correct me if im wrong but i also have a 3 layer headgasket in there so maybe the turbo is just too big now cause of my compression right?

 

Change your intake manifold.....I had the Victor X on my stock b16 and it sucked for daily driving. I switched to a Skunk2 and the car picked up 14 whp (286@7 psi) and it brought the powerband back to usable rpms. It will make an enormous difference if you switch to a S2.

 

i was thinking about that too, but do you think my turbo might be too big? is the edelbrock designed for high output drag cars?

 

Hey man ive got that same motor setup but i havent turbo'd it yet....my turbo kit is on my Sohc....my sohc made 230whp at 10psi.....my setup....450cc injectors on the hack. t3 turbo....you turbo is wayyyy too big.....oh yeah my b16 gsr head motor......is fast as **** NA.....I think that swap raises the compression....

 

The turbo is not too big, I ran an SC61 on my stock b16 and it spooled quicker than that. My money is on the manifold. Edelbrock manifolds are designed for high rpm's and do not work well on mild setups.

its fast as hell NA? i hated mine before i turboed it. barely any power, but i also have 3 layer headgasket and colder spark plugs too so i dont know. i think its most likely the manifold but i would really like to get to the bottom of this.

I could have sworn that was my catalytic converter you never returned?

actually i dont know where that one went , it never fit, i bought a new one a year ago from exhaust works. anyways ttt

 

Yeah with a stock *** clutch I was shifting into 3rd and that bytoch was lettin loose.....lol....yeah you turbo is def too big...i mean i almost made the same power you did on a stock sohc....lol.....somethin deff aint right....get a t3 with a .48 hot side and a .63 compressor side.....youll feel a bigggggg diff....your turbo sounds like a TurboNetics...

 

Can anyone tell me why that turbo is "wayyyy" too big? This is just the typical h-t bandwagon effect.

Its a t3/t04b .57 trim that comes with a drag kit. That turbo is sized pretty decently for that motor and it gives him a little bit of room in case he ever decides to do a mild build. I ran the biggest SC61 that they make (rated to 680 hp) on my stock b16 and the lag wasn't nearly as bad as his. Its the intake manifold, not the turbo.
