- a short video to demonstrate physical differences between the g25 g30 and efr 6758 . some information provided is information I couldn't find else where so hope it helps other people with choosing the turbo of their choice .
What would you recommend for fast road sr20det looking for 500-550 whp
For me i like my k04 borgwarner..i decided to upgrade my turbo with efr series for more hp and tq..but most people say go for g25-550 series..but efr turbos boost start in low rpm which is great..but some people say efr turbo got so hot and breaks easily..do you think it is true ?
Did you find this information bro? Im looking for this answer nowadays...i need early spool but reliable 450hp
Thank you so much ! Very informative !
Brilliant. We're did you find the g30 with an internal gate? Couldn't find them when I looked.
Garret do list on their site . But garret have had supply issues so lot of units you cannot buy yet . The one in my video is a pulsar / Chinese copy of the garret . They now do 0.72 and 0.92 iwg housing for g25 and g30. Normal and reverse rotation
@@garymgzs280 brilliant. Were is the best place to buy them?

Hello! Which model turbosmart iwg fits the pulsar g25? Thank you!
Its iwg75 uni. It has to be modified a bit to fit
@@garymgzs280 thank you!
EFR6758 vs G25-660 - which one would you recommend and why? I made 520whp with the EFR6758 .64 on a 1.4L engine. would switching to the g25-660 ar .72 be a downgrade?
I couldn't really comment I'm afraid. So many variables.
Sounds great! I run the same turbo on a 2.0L engine and i was afraid it will max out at 500whp so now after reading your comment i hope to see some big numbers too.
@@alek_gk for sure it will do more than 500whp when it makes 520whp on a 1.4L ;)

The EFR will spool earlier and be more responsive. The 660 has more peak power.
how did the internal gate flow? was it big enough? what psi are you running?
I'm at 25psi . There's still more in the turbo but I'm on stock internals still .
@@garymgzs280 did the gate flow enough to control that or did it boost creep?
@@darrenweller9160 it's steady. So yea internal gate works fine
G series turbos have 38-40mm diameter wastegate ports so compared to the old T25 GT series 25mm ports I think it's enough when used with engines like SR20DET which need high boost to make power anyway. My GT3071R with .64 rear housing did creep to 1.5 bar no matter what, but my current .86 keeps it steady at 1 bar if I for some reason would want to run just that amount of boost
Great video , but which of these is the simplest to fit with least amount of mods or hassle
The g25 and g30 will be simpler to fit. The v band mounting point is very easy. The t4 divided flange of the borg will need more fabrication work and getting the 4 nuts on and off is a pain .
@@garymgzs280 thanks mate , I would love to see more technical videos regarding the engine , I have a manual Vauxhall Some Signum with this engine and there are not many videos on it.
Like adding a bigger inter cooler , replacing injectors , timing chains , and other stuff
@@medievilassassin ah right. So you have 2.8 v6. I have a few other videos specific to this engine. Just post something as and when I'm doing something on someone's car
@@garymgzs280 yeah I have had it for about 1 year and love it , thought it’s now on 155k but with full service history and I fully serviced it myself , plugs , oil , filters , coolant , water pump and belts.
Plus oil pressure switch as I thought it was leaking but I thing the power steering pump is leaking.
I wanted more power out of it but unsure what mods to do before hand
@@medievilassassin how much power you want.
Upgrade intercooler is a must . Do88 have that covered.
Remap by aura tuning. Check the Facebook page.
And upgrade actuator. I sell turbosmart ones. You can find them on ebay. I sell them - ebay name saabmadman
An EFR is $300-500 cheaper than a genuine G series and is arguably a better turbo in many ways. Not saying the G series is bad, but it's not cheaper and you can get various flange options.
thats exactly what i was thinking you can get a vband flange on the efr and it includes more
@@digital0785 They have some seriously impressive stuff.
How was the pulsar holding up?
Yes up and running now . Made 514bhp . Sounds great and pulls great . Very happy
@@garymgzs280 very nice is that on the g30 ?
@@jordancespedes15 yes . G30-660
How much boost and what engine you have this G30 660 installed ?
You can get the 6758 vband in and out...
what is a pulsar turbo? is it a Chinese knockoff or something
Hi there . Yes a Chinese version of popular high end turbos . But they are midrange branded turbos. Good reputation. And very popular in the drift scene
@@garymgzs280 very good quailty turbo
@@Arss-ast I just received mine but I have to say that I don't really like the wheel play ... not sure how long this will last on high boost
@@low-budget-racing how did it hold up?
@@vladbc9172 works good - but in my opinion the EFR6758 was more efficient on my small 1.4 engine
Pulsar turbo have good quality
“The two Garrett versions” no they are not. They are Chinese copies of the original Garrett turbos and not even that, as they have used cheaper materials. Just call them Pulsar and stop referring to Garrett as they are NOT.
Umad bro
Garrett, Are made in China, Mexico, Brazil Not the United States. They haven't been for over 45 years.
So don't hang your hat on Garrett.
