Gt35r Vs Garrett T04z - Discussion (just Post In This Thread To Create A Database)

[Lithium]

Will see if I can get one off him

[Jap_Muscle]

his about right.. my rotor when i had it made 392rwkw on 19psi... so his pretty on the ball

might be a bit more believable on a rotary.....but i still find it hard on a rb30

[Jap_Muscle]

id be interested to see any gt35r with a .86 rear make more then 360.

must be my car if i cant get there llol

[unique1]

Dcieve on these forums made 400rwkw on a 0.8 gt35, it had abit more than 19psi but they can definately make the numbers and from the best of my knowledge his doesnt have any headwork at all, only a set of poncams.

[Bumblebee]

ohh my bad.. i had a 1.06 rear on the rotor.. .82 is wayyyy too small

i think i do mate, and the actual dyno he used is known to be very low reading as well, it would make around the 550rwhp+ mark (417rwkw) on most dyno dynamics dynos in Perth . Its in a r31 and runs 131mph on the one pass he did before he broke the axles. I aint making it up its proven

put the cars weight in the drag calc (around 1440kg or so with driver from his last weigh in) and it says 420rwkw for 131mph! The drag calc is almost spot on for every other car ive put in.

[Jap_Muscle]

well i guess ill stand porven as soon as i see something to back that up

[unique1]

lol unfortunately i havent got his dyno sheets or drag slips or i would

[Strik3r]

Noel (FineLine) made 520hp (damn close to 400kw) with a gt35r .82ex on an rb25... also has an 11.2 @ 126mph (if i remember correctly) to back it up

[DCIEVE]

.... or you could just read the thread.

[Rezlo]

From my side of the world GT35 .82 on RB25 with poncams

KW at wheels. Car has run an 11.3 @ 129mph on an unprepared track.

[Jap_Muscle]

That's a fantastic effort there rezlo. Do you have any more specs on the car? Looking at your sig it seems like you put a rb25 in your silvia? No rb30? Ported?

How much power did you make with the t04z?

[Butters]

Another GT35 example 455 rwhp @ 17psi on a stock RB26(just ecu + injectors).

Car has run 10.35 @ 128mph.

I actually have a t04z as well but am finding it hard to justify upgrading when there is so much more left in the GT35.

Graph scale is a little off redline is actually 7800 so move everything back about 200-300 rpm. Also boost controlled with $50 bleeder.

im totally with ya there buddy.

im trying to reach the 400kw mark and find ti very hard with a gt35r, but alot of ppl are saying its possible. so before i buy a to4z i want to make sure 100% the 35r is out of puff.

That dyno is a customer of mine. Basic RB25 build with some mild porting, CNC blended combustion chamber, greddy intake mani, hand build exhaust mani ectr... its in a S13

I ran the identical combo in my S14 (besides the CNC blended chamber) and when I upgraded to the T04z twin scroll (I sold my GT35 to him) it was a massive change, the car is more responsive, more mid range and faster spooling and at 2 bar its more fear than fun (it is still loosing traction at over 140mph on 285's at only 1.8bar -

)

There is nothing wrong with the GT35, its a great all round turbo thats easy to get good numbers out of, that said if you take the time and run the right manifold setup on a T04z it is a fantastic turbo....

Having owned and driven both turbo's on the same car, same managment, identical motor ectr what would i built my car again? T04z again,,, all day every day. That seems to be the general outlook, the guys that run T04z's on GOOD setups love them, the guys that talk shit about them most likely have never been in a properly setup T04z, that or they try to defend their purchase of a GT35 and aim for a lower power rating.

So again, I like the GT35 (especialy on SR20's and 4G63's)but I think results in a T04z all come down to setting it up right and when setup right it will outshine the GT35.

[DCIEVE]

If you've run them back to back where are the plots to back up the claims?

I've compared plots of a properly setup hks t04z on a full house jun 2.7 and it makes a bucketload of power but I wouldnt in any way suggest its more responsive or has better mid-range than the smaller gt35.

[sky30]

i dont think you realise what you are sayiung.

So your telling me you know my car better than me and i dont make that sort of power just coz you cant do the same with yours?????

It run 170km/h in the 1/8mile, whats that tell you??
