Good afternoon guys.

Im in abit of a predictament with what turbo I think I should use on my standard b18c4 which will be going into my ITR. I'm aiming for around 300-350 at the flywheel but when i decide to forge it later on down the line i may want to push the boundaries abit further. I thought I had always had my heart set on the GT2871R T3 Flanged .63 A/R with a vband exit for the downpipe because I want the car to spool up nicely for the B roads we have here in the UK but Ive just been out in a friends EK civic turbo which was a completely standard engine with the T04E T3/T4 .63 A/R 57 trim and i loved how the car performed. is buying a ball bearing turbo worth the extra cash? the EK turbo felt great when it came on boost around 4krpm and it was 290 bhp at the flywheel.

Ive pm'd TheShoden but havent had a response yet and wondered what you guys thought the comparison between the two?

Are these turbos massively different and is the gt2871r worth the extra cash?

Any help would be appreciated and thanks in advance

 

Ball bearing is more durable and there is definitely a difference, especially in transient response (off throttle to on throttle)

 

The whistling noise from the compressor cover style (anti surge) than the bearing system.

 

The GTX3576R only came with a ported shroud housing. There was not GT3576R until the GTX line was released. So you either don't have GTX3576R, or you have a hybrid like a GT3567R, which is different, and typically doesn't have a ported shroud housing. Which is what makes that sound, not the bearing system. And yes, some ported shrouds sound louder than others. The ones used on GT3584R turbos sound quieter than the GT30R-based covers.

Do all ball-bearings sound like this?

Here's an example of what I mean. 2000GSRTypeR's Build using a journal bearing CHRA and an optional Ported Shroud compressor cover

2000GSRTypeR's build Page's 6-11

His video with that same turbo is here. Remember, this is an oil & water cooled Journal Bearing CHRA Interceptor turbo. note 0:20:-0:35 seconds of the video.

 

My brother has an 86 Z31 turbo. Just had a custom flexplate, bellhousing adaptor plate, and torque converter made to put a turbo 400 chevy trans in it.

Back on topic: In my opinion on small 4 bangers the Dual ball bearing units are worth it cause you need all the help you can get. On a larger engine I would go journal bearing all day.

 

Oh come on, why is it everyone has this sentiment? I've seen plenty of successful journal bearing builds at and above this power; in this range he could even use a straight super 60 or a mitsu turbo and have full boost around 3-3.5k which is plenty fast, yes maybe slightly slower throttle response but unless you are doing serious circuit racing that probably won't matter.

 

My B18 with ITR cams and GT2871R on T2 flange running 23 inch slicks, was at 16 pound of boost running constant 11.7/8 at 122/3 weight was 1180KG
This gives you and idea of response and general idea how it produces it's power, it's served me well since 2007 and is a perfect turbo for the road.
Just my opinion, selling it for a GTX3576 and a CSS block now.

 

I love the GTX3576R. There aren't a lot of them out there, as Garrett made a limited number of them to distributors.. But they are cool if you can get them.



Then there's the Predator R, which is similar in characteristics to a GTX3576R
It looks like this with the right options.

This is Frost EJ1's Predator R

 

Is it gtx3567r or gtx3576r?

 

Sorry. Corrected as shown in my edit comments.. GTX3576R

 

I love my garrett gtx3576r.

 

So would you guys say the gt2871r is worth the extra money over the T04E?

 

Why are you looking at the To4E 57trim over the 50trim? I think you are in the same boat as me, look at these.

Hunter T04B Turbocharger

T3/T04E "50" trim Cast Turbocharger

 

I'm interested in the 57trim as I have a friend who has one who will possibiliy sell it to me for a good price.

That's how I came across the T04E before hand I was only Interested in the gt2871r

 

Well more than likely you will get the 57 trim for around $500+/-

The GT2871r will run you $1,000...

Will it give you double the performance? Probably not. If I were buying new I would look at everything but the 57trim though.

 

???


Just go with the 57 from your friend based on the price and condition, if not look into a 50 trim perhaps.

 

He said around £500 so I thought that was reasonable. The gt2871r is going to cost me around £800 brand new

 

Stopsign said that you would get one for around 500USD. Is that actually what your friend is going to give it to you for? Plus look around for used 50 trims, as they can work well too and should be a similar price. Though not common, there are smaller t3/t4s than 50 trims, and also there are the mitsu turbos you may want to look at. Remember that for this power goal if you go journal bearing the smaller you go that will still be able to provide the power you want will net you faster spool.
