Rb20 Turbo Upgrade Advice

[040122]

Hey guys, I got a 32 and am looking for bolt on turb upgrades, I've been concidering the rb25 turbo as an easy up grade for money performance and easy to find but opinions would be good and if anyone can say what the rb25 turbo can handle cheers

What are you trying to acheive? A Hypergear RB20 turbo Hiflow was good for 216rkwk on 98 and 242rwkw on E85 for me, of course it'll depend on your other mods and your tuner etc.

what are you looking to spend? budget wise? way better options than an rb25 turbo but depends on what you want to achieve/spend/already done

RB25 is the cheapest upgrade, but a long way from the best. You still end up worrying about whether it will spit its turbine, and it is obviously a very old turbo for the money. Someone else's secondhand highflow may be a bit of a gamble, but would be the next best option (in terms of $$ and possible performance) as long as it is a reputable one and not a mystery spec. Then from there you can only really consider a new highflow, like the Hypergear. That would be the most $$ you'd want to spend, and will get you the best result in terms of performance and life expectancy/reliability.

K guys anywhere up to a grand is the budget, I'm looking for a bolt on with good response (less lag than stock) and would like to achieve about 230kw eventually, cheers guys

Bolt on with less lag than stock for $1000. I don't see how this is possible. The rebuild for my highflow with a braided oil line from Hypergear was about $1000. I assume it's laggier than the stock one since the stock one has a ceramic wheel and the highflow has steel. Response is still pretty good for a 2L, but if you want 230rwkw assuming 98 fuel I'd say the highflow of an RB25 turbo would be the way to go, same cost I think as the RB20 high flow, but will be laggier again.

LESS lag than stock but want a larger turbo?

What ever turbo you put on it wont feel as good as it could be without a tune so keep that in mind.

This is very true. Even the rb25 will increase boost onset by 750-1000rpm or so. I ran an rb25 turbo on my rb20, and whilst it was a pretty good upgrade over stock, i found myself needing to upgrade again a few months later on due to wanting more power. Your rb25 turbo will get you a safe 180(+/- 10) rwkw on stock injectors.

I don't mean to sound like a broken record mate, but don't forget supporting mods if you have none to date (ie, fuel pump, clutch, engine management, etc) If your budget is just for the turbo alone, then highflow is the way. But if you still need to tidy up the other supporting gear too your $1k budget wont stretch too far.

I got few things, nisstune, splitfires, boost controller, wallbro fuel pump, big cooler, and have gtr injectors sitting in the cupboard, im trying to put them in at the same time as a z32 afm new turbo and tune, I just got no idea about good turbos....besides ebay and gumtree I dont even know where to buy a turbo....fish out of water

Thats good man, you sound like you're almost sorted. Is the car still on a stock clutch? If so you'll find it'll be slipping after a power up.

I highly recommend a Hypergear atr43, for price and ease of fitment!

Save up for a tad longer, and you wont regret it.. rather than getting a chinese ebay turbo or s/hand rb25.

For 230kw HyperGear highflow would be good for price plus keep everything stock looking if your into that or you can look around and try to see if you can buy a used 2530 turbo.

[040122]

Yeah I like the stock look, it keeps you out of trouble with the law, sometimes.

[040122]

So ive been looking at the atr43 off hypergear site, I'm unsure if the turbo comes complete with everything to drop in or if I need to get other parts eg waste gate oil lines etc I got no idea haha

[hypergear]

For high flowing its physically still the stock turbo with larger and steel wheels. So it will be a drop in replacement. The ATR43SSxx with .60 comp housing would require a metal induction pipe (must have for high performance either way) and a 90 degrees long legs silicon reducer from 2.5 to 2 inches. Braided oil line is usually supplied with a high flow or a brand new turbo.

K can you pm me some prices including all the mods that need to be done on the atr 43 ssxx thanks

Personally , i would never put a 25 turbo on a 20 again after the last 3 that i've fitted have felt far worse than the stock turbo . For the mods you've listed you have , i would aim for either a kando td05 18g , td06l2 20g or what hyper gear stated above (which would be the easiest to fit) , another option is the kkr/jjr430 seem to work well on the lil 20 (flame me all you like , in my experiences they are better than a hks gt2530) . All comes down to how much you want to pay . out of all of those turbos , the jjr would be cheapest over all to have on your car running , i'm not sure on the price of the hypergear but expect the 2 kando (trust copies) to cost $1200 upwards (fitted) depending on who you know and how much you can do yourself.

I had a highflow on my rb20, highflowing the stock turbo is prob the best way to go, I had 232rwkw and wasn't that laggy, 21psi by 4200-4500 or so.

[Missileman]

if you do NOT want lag then ask mr hypergear for the apropriate hairdryer.

any extra killawasps has its price, and lag is what is usually paid.

[040122]

By the way thanks for everyones opinions its been a help, does anyone have opinions of hypergear vs td05 or td06

[Roy]

... am looking for bolt on turb upgrades,

Does not equal

.... td05 or td06

I think the TD06 is a ripper of a setup but is a long way from a bolt up and is really a 260rwkws option. If you want bolt on then its hard to go past a hi-flow using the housings that all your piping currently bolts up to
