Hi I have been looking at going single turbo on my FD3 and was planning to get a Holset.. However a tubonetics turbo has been offered to me.. it is the 62-1 0.96A/R. It is presumeably an older version as it does not have the ceramic roller bearings in it? and looks a little different. Will this be any good on my rotary and what bhp is it good for?? I am on stock ports currently but wil have plenty of fuel to offer it! What boost is this turbo capable of running?

Here is the turbonetics link.

Thank you

Ive had good luck with mine!

Ported motor 20psi 500 h/p> turbonetics 62-1!

Should do easy 400 h/p if tunned well!

 

Thank you for the reply..

Am I correct in reading that there are two compressor sizes and two exhaust sizes options on this turbo? an A/R.63 and A/R .96??

Which are you runnning? Are you able to post a pic of your turbo for me to compare to the one I am looking at please?

Thank you

Lee

 

i'm going to be running a T62-1 w/ .96 a/r. That turbo is available in a variety of exhaust A/Rs, but the .96 isn't available in divided housing.

Give me a few more weeks and I'll give you more info on how well it does on my car =]

 

The 62-1 is available with many exhaust housing options, one of them being the .96A/R(preferred one on rotaries from what I have seen). I think the .63A/R you are also mentioning is way too small for use on a 13B. If I am not mistaken the compressor side of a 62-1 is 62mm inducer with a .70A/R unless you go with a Hi-Fi version(62mm inducer with a different A/R) but that wouldn't be beneficial to you.

Can anyone else elaborate?

My advice is to never go below a .81 a/r turbine housing.

 

I guessed the A/R 0.96 housing is the one required for the rotary. wondered if visually there is a noticable difference in the housing size so I can be sure I am getting the right one? or will if have something stamped into the housing? Is the Hi Fi compressor no good then?? I reckon it might be that? the inlet looks quite small compared to the one pictured on the turbonetic website. I can try and get a pic a post it up later.

Cheers

The exhaust housing will have the A/R number casted into it near the 4 bolt flange on the rear. Also, I didn't say the HiFi wouldn't be any good, I said that going HiFi from a regular 62-1 wouldn't be beneficial to you. the HiFi squeezes the same compressor blade into a lower profile housing. The benefit is that it is smaller so it fits easier on some cars(RX-7 not being one of them, plenty of space) the trade off is 10% less flow. You can probably still get pretty good numbers on it though.

Turbonetics makes turbos. For the money you're spending you would wiser to get yourself a GARRETT TURBO GT35R, 84 TRIM, 1.06 A/R. This system uses newer and better turbine technology. This one is good for 500hp. Please do not support old technology.

 

The 62-1 i have is a .96 ar.
It has a 4'' inlet and a 3'' band clamp exhaust!

And as for old tech. i guess it is but 10.8 1/4 and 10.5 comeing without going above 500 h/p suites me fine!
Whats your track time?

 

Why would you want to use "OLD" proven technology. That just doesn't make sense. The 62-1 should outflow a GT35 at lower pressures.

 

Thanks guy's
I agree partly that this 'old' technology did us just fine before the new stuff came along!
anyhow. I am looking at this unit as it has come up cheap and has hardly been used!.
Here are a couple of pics of the unit. any ideas on what size she looks like as I am not getting an answers back yet! Also is that an on-cenre type housing I see?
If it is does that mean it's no good to fit the RX7?






Thank you

Looks to be an on-center T4 housing..somewhere in the 0.8X A/R range.

On-center isn't as efficient as a tang (tangential) housing and it will sit different on the manifold as a result. By sit different, I mean stick further away from the mani....but depending on the manifold setup it could fit. RX-7 engine bays have a pretty good real estate in the turbo area.

 

the turbine housing A/R should be cast into the housing... look inside the manifold flange area, you may need to clean off the carbon build up

 

I used an on-center housing on my brother's car and I regret it
You can, however, buy a new tang housing--- divided or undivided and in different a/r's usually for around $150. Just make sure that it's for the correct trim wheel that this turbo has.

 

Sounds like it will be better to give it a miss! I thought it looked like an on centre!!
