who's running this turbo on their car? i heard this is the biggest turbo that will fit under a t04 manifold? the spec i'm going to run is this

62-1 turbo, A/R 70 compressor
with the 4 in funnel shaped inlet
P-trim exaust wheel and shaft
a A/R 1.0 exaust housing

what kind of power do you think i will made with the setup?

jumbo street port
2mm hurley seals
hks intercooler
hks catback. dp and mp
twin power
fluidyne radiator
2 walbro pumps
1000cc primary and 1600cc secondary with k2rd rail
sx fuel regulator
power fc

can i made 500rwhp with about 15 to 17lb of boost on pump gas?

Thats my new setup, but I haven't installed it yet. And to tell you the truth I'm not sure what to expect out of it either.

94touring. which hks manifold are you using? the t04e or the t04r mainfold? and fitment problem with it? I ordred the turbo today, hopefully i will not have to spend the money to buy another manifold lol

I think theres a guy name tony, I think thats his' name, drives the camelian color fd made some where around 415@15psi. im not sure, that might have been at 18. It doesnt sound right at 15 psi with a 62-1..

Bridgeported

On a streetported 13B you should be able to make up to 475 rwhp. How much YOU will make depends on how well your EMS is tuned, how much boost you running, and all your other critical components as well.

Here is a few numbers that aren't too far off:
375 - 425 @ 13 - 18 psi
400 - 450 @ 15 - 22 psi
450 - ??? @ mid-high 20's

I assume its the R, I bought this kit off a guy. The part number is HK1419-RZ003, and the manifold is beautiful.

94touring

Well all I know is this turbo is much bigger than my apexi turbo. I run 18psi and really expect to be making at least 425rwhp, especially since my apexi turbo is around 400rwhp at that boost level. There is just so much less restriction on the whole kit, manifold, downpipe where it connects to the turbo, and the turbo itself.

62-1 is much bigger? wow, I didnt think the apex kit was that small

yea, tony from www.rxecret7.com has the 62-1 turbo.

rx7 rage, do you know how much power is tony pulling? and which manifold he is using?

Do you think the 1.0 exhaust housing may be a bit too small on a P trim exhaust wheel? Specially if you are going a Jumbo street port.....

I run a 1.32 exhaust on mine and I find it suits mt style, but it may make peak torque a bit high up for your liking (6700 to 6900rpm) I just hope the 1.0 does not cause you too much back pressure, hence costing you power and a bit more stress to the engine?

I dynoed mine at 472rwhp on a dynapack dyno @ 19.9psi boost (228kpa absolute pressure) which = just over 490rwhp in dynojet language in street trim (mufflers & air filter, pump fuel etc). My turbo is basicaly the same as the one you are describing but with a bigger exhaust.

94touring

The exhaust side on the apexi is smaller, noticable. I believe its a .89 or something.

Rice racing,
I'm not sure if the 1.0 ar is too small or not, that turbo setup is what my friend is running over in japan, he told me he is very happy with it, then again, i'm sure if his port is as big as mine. Do you think i should go with a bigger a/r? what is my advantage of going to 1.32 like your?

94touring

Well aren't the specs on the HKS to4s the same? The HKS to4r is a 1.15 on the exhaust if i'm not mistaken.

Yeah I am with you it would be good to get feedback and see, I have used a 0.96 housing on an engine a while back and it did make nice early boost with crazy mid range go realy strong from 4k to 7k.

The same car we put on a turbo like the one I run now and it feels stronger from 5.5k to 8.5k, so it basically shifted everything up in the range. Power went up without having to increase the boost level. I know the back pressure on the engine is less which should make it & the turbine side more reliable. I have found on some hybrid (or smaller exhaust housing) turbos that when I have used them on engines where I have ported them allot (especially in the exhaust) that they suffer more than a stock or mildly ported exhaust engine when the back pressure in the exhaust manifold gets much higher than the intake manifold pressure.

maybe if you want to 4k to 7k range of power or there abouts stick with the 1.0 and dont go too crazy on the exhaust ports ? I know turbostreetfighter experienced a similar thing recently on some of his projects, maybe you should PM him too for some thoughs before you decide on the combo of parts ?

RICE RACING

Those kits are designed to be bolted onto std engines I thought ? Maybe if you ported the engine allot you will find that the bigger exhaust housing will match your new engine better ? Just an idea...

The std exhaust ports in every turbo mazda 13B are very small and have little overlap, I am guessing HKS pick that housing size on the TO4S to be a best solution for the std engine, also to give the power in the 4k to 7k range maybe too ?

94touring

Thats very possible. Although I hold constant power on my apexi kit from 4k-7k before it begins to drop, and like I said its even smaller with many more restriction factors beyond just the turbo, but still has a decent power band. We'll see though, i'll be hitting the dyno sometime after I get everything installed.

singleturbofd

4 to 7k power band is perfect for me. this is a street car. love to made full power down low.
94touring. when are you going to dyno your car? you are also running the 1.0 a/r right?

Marcel Burkett

I have a 1.32 for sale if you'd like.Correct me if I am wrong but didn't someone say that the 62-1 isn't well suited to the rotary because of ite efficiency range and compressor surge occuring ? , that it is safer to go with the 60-1 or T66 and up ?.

94touring

I am hoping that my buddy and I who is buying my apexi kit are going to hit the dyno soon after we get everything installed. And yes, I will be running a 1.00 a/r.

Marcel,

The 62-1 turbo should not surge on a rotary by looking at the compressor maps, very similar to the 60-1.
