Hey guys not sure which turbo will suit price/power/stealth

im after a turbo which is undetectable by cops, has more power than stock and isnt too expensive and has minimal turbo lag.

ive been looking at this hyergear g1 400hp rated turbo, its a direct bolt on for rb25 and its $1250 i have a jjr split pipe coming too so i wanna hit it all in one go.

rpm range for boost is 1500-3600 rated 20psi

link : http://digi-hardware.com/atr43.html

can i have this turbo on running 8psi like what my current turbo is running now and should it be fine? or do i need pfc with it?

current mods :

- 3.5 cat back

- return flow FMIC

- HD clutch

- BMC panel filter

the final power figure im aiming for eventually is whatever the injectors can throw out safely so 220? with 80% or 90% duty? not a gun on this part.

Thankyou in advance!

Absolutely agree with the above. Hypergear's hiflow of your existing turbo will be the closest thing to your stealth requirement and cost less than the ATR43. But don't upgrade your turbo if you're not going to upgrade everything else. At minimum you want Nistune, fuel pump, intercooler and 14 psi, + turbo upgrade or you are wasting your time. And that's just to take you to the limits of your stock injectors. Time for you to read a few sticky threads I think.

Sorry forgot to mention the main reason for this post, my turbo is making loud noise like a sander on a piece of perpex. it gets louder and more noticeable as it pass 2-3 mins of consistent WOT.

under normal driving conditions there no unusual audible sound.

thanks guys.

so best option is to get my turbo high flowed? what will the power rating be with bigger wheels on it? turbo lag etc?

2 to 3 minutes of consistent WOT... Where are you driving that thing, across seven airport runways in a row?!

Where is this place I want a go

i had this high pitched noise on my old GTT, thought it was poss the turbo but in the end it was the FMIC which had a slight leak around one of the silicone joiners. So i just pulled it all apart and put it all back together making 200% sure all was nice and snug, and got some good clamps and ditched the ones it came with. Norma ones i think?

i had a highflow hypergear on my GTT as well, nice bit of kit. Stealth, punchy and plenty of fun in a rwd Skyline. 250rwkw ish on 98. 280'ish on E85.

But like the others, no point getting the turbo, dump etc without getting something to tune it. As you have a R33, you're better off getting a power fc i reckon.

no doubt ill be gettin a pfc just wondering if i should rebuild my one or be looking at something else. whats the differences between a rebuilt highflowed r33 turbo compared to a hypergear g1 turbo in regards to power/response/ boost/cost etc.

2 to 3 minutes of consistent WOT... Where are you driving that thing, across seven airport runways in a row?!

He was actually driving an R32 with an RB20 in 3rd gear and at 3,000 RPM. It was slightly uphill.

Like others have said you will need to upgrade more if you are changing the turbo, seems a waste to upgrade the turbo and only get 1/10th of the upgrade it can offer. This is what id be doing

Fuel pump

Some sort of injectors if not an adjustable reg

3 inch dump

Aftermarket computer. Weather it be a nistune or power fc

Maybe a EBC

Z32 afm

Turbo

Tune

But doing all of that if a cop sees something he does't like he will defect you, so really if you went for a garrett a trubo is going to be the least of your worries as he will probally get you for to low etc.

sweet guys thanx for all ur help. Im gonna just drive it around like a granny till i save up for a hypergear highflow, pfc, injectors, fuel pump, 3" turbo back, ebc, z32 afm or map sensor. and a sexy tune!

sex!

thanks again guys.

-split dump

-venom hi-flow cat

Get those done first.

What sort of CAI are you running? If you haven't already upgraded that yet do that before you go altering the turbo. Even if it is just a good panel filter in the stock box.

    • Yeah, the latter. No diff should have a centre replaced without checking clearances because its unlikely to be the same as whatever came out. Not that that stops most people just checking a new centre in
    • Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?
    • in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.
    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
