T70?

[Young GT-R]

Ok, I couldn't find anything of value so I thought I would ask how the T70 turbo's go with an RB25 motor?

.82 exhaust size with a 60.5mm front wheel is the one I am looking at.

I am ok with a little lag, ie it starts boosting at 3500rpm.

but do they come on at 5k or something ridiculous?

Not after opinions on the quality of a T70, just what they are like on a 25 please.

My mate one tuned one for a customer rb25det and it made 420rwhp on 19 psi. it made full boost at around 4000rpm

that's the answer I was hoping for.

have got 550cc injectors, haltech ecu etc etc, so I figure if I see full boost by 4k and I am making high 200rwkw's, they must be a good "cheaper" turbo then.

cheers

sounds like a lot of assumptions to me

there would be better turbo's out there for that power level

[sinistaGTR]

ummm the one i had on mine that blew up......hit started boosting at 4800 and full boost by 5400.....absolute lag monster dont do it

[Guilt-Toy]

420rwhp is about 300rwkw

that's the answer I was hoping for.

[Young GT-R]

assumptions?

Why do you think I am asking the question here?

Got an answer that relates to an answer I got elsewhere that they are pretty good on a 25, but laggy on a 20.

The 20 I speak of made 24orwkw on 19psi.

I plan on running 16psi in the 25 and anything between 250-300 rwkw will be a big jump from 204rwkw that I had last tune.

Saying that, it's more a question about lag.

[Young GT-R]

4800rpm started boost? what supporting mods?

what turbo are u running now sinista?

[sinistaGTR]

yep thats right boosting at 4800, i had power fc, the usuals no internals, too get it to boost early like 4k you would need a good set of cams. and im now running a gt3040. your better to save your money and do the job right first than waste $500 or however much they are, i learnt the hard way money down the drain and i had a lag monster.

[Young GT-R]

is the 30/40 much better?

ballbearing yeah but same size turbo aren't they?

[sinistaGTR]

gt3040 or a gt3540, is a million times better. you can choose your ex. housing size for your response you want. there excellent quality, ball bearing, water cooled. i really wish i went that to start with instead of trying to get cheap power that just cost more in the end.

[Young GT-R]

only reason I ask is I have a mate with a 20, who has a GT30/40 with the .63 exhaust and he doesn't really see boost before 5k.

In an ideal world I would get a hks gt3037s, or a gt30/40

[sinistaGTR]

well gt3040 with .63 on a rb25 is boost by 3200....all the way through

[Young GT-R]

well I think the old faithful might e the go, spend the money first time.

[r33_racer]

I had one also on my rb25 and didnt see full boost till about 4800-5000rpm...was a mass lag monster. On 17psi i made 350rwhp with supporting mods and all, no cams though.

then it ceased up cause the shitty oil line i used got blocked up and starved the turbo of oil.

Now have a gt3040 with .63 rear, much much better

[sinistaGTR]

yep good to hear young gtr that your gonna spend your money right the first time, you will much much happier with the result and longetivity of the turbo. haha r33 racer....how similar i like it lol.

[Devils_Advocate21]

T70 Ebay is your friend? LoL as above dont do it unless you have lots of recovery money

[Young GT-R]

yeah, will be a little while, but thought I would ask cos I had a full kit offered to me.

thanks for the input, must be ballbearing, .63 a/r sounds like the go.

[l0WRB]

i got a friend who has one of these t70 turbo's off ebay..its making around 293rwkw @ 18psi,bit of a lagg monster but once it comes it comes on HARD..has been for last 5months..never missed a beat..i dont understand how u guys break them so easily?

[sinistaGTR]

yeh had mine on 12psi for four months......its pretty hard to break a turbo unless there crap
