Hey guys i just bought this turbo... I dunno exactly which turbo it is... but the guy i bought it from said that it is ball bearing...I sat in his FD boost build up was good..

please tell me which turbo it is if anyone can make out..



Also how much HP should i expect from it on my FD..



Its very late in the night and the only thing i could get to give an idea of the size of the turbo is a Gillette MachIII ...i think it is the same size worldover https://www.nopistons.com/forums/pub...#>/biggrin.png



Please help me in identifying this turbo...



Thanks

here is another pic

Measurements, we need measurements. Start pulling it apart and use a vernier caliper to give some wheel measurements, inducer and exducer on both compressor and turbine wheels. I am sure someone will chime in on what it is.

To4e compressor, possibly a 57T wheel. Show a pic of the exhaust side.

Yea looks like an E...

Will try my best to show the exhaust side but the guy i bought it from welded a flange to it so the view is somewhat obstructed...



He also said that it was an HKS unit... How much HP should i expect from this turbo on my FD... How much difference would i feel considering i am upgrading from stock twins at 10 psi....



Also the guy did not give me any measurements can i measure myself.. how do i do that??



thanks

Can these be the specs of my turbo



COMPRESSOR:

-Wheel- 57 Trim - 56.3 Inducer / 75.0 Major

-Housing- 100 Inlet / 60 Outlet - 0.60 A/R

TURBINE:

-Wheel- 62 Trim - 74.1 Major / 58.1 Exducer

-Housing- T04 inlet / Insert type outlet - 0.70 A/R





Found these on the HKS USA website...

Dunno, if those specs are for your turbo. Pull the bolts that hold both the compressor housing and the ones that hold the turbine housing; use a ruler and measure across the top of the wheel as precise as possible from tip to tip on both the widest part (exducer) of the wheel and the smallest part of the wheel (inducer) and post the measurements (crude method). A vernier caliper would be even better to measure it with. Someone here will certainly be able to help. There is a thread about a similar turbo info request and he got a ball park idea as to the turbo he has.

Dont be afraid to pull stuff apart, thats the only way to understand how things operate. https://www.nopistons.com/forums/pub...DIR#>/cool.png Just dont damage the wheels while pulling it apart. https://www.nopistons.com/forums/pub...IR#>/blink.png https://www.nopistons.com/forums/pub...1047683664.gif

Pictures say alot more than words. I took the liberty of taking some pics. showing what is required. Now don't pull your wheel off like this https://www.nopistons.com/forums/pub...DIR#>/ohmy.png , I had this one sitting in the garage. https://www.nopistons.com/forums/pub...1047683664.gif



Compressor Inducer measurement = 58.22

Compressor exducer measurement = 84.00mm



From the measurements I can tell you this is a T58 wheel.

That is not a 100mm inlet or a 60mm outlet on the compressor. Could be a 57trim wheel, and is an AR.60 compressor housing. Without seeing the exhaust side there is no way to tell what it is, but you should hope that it is not the O trim AR.70 exhaust side that you gave specs for. HKS offers the same compressor section with an AR.84 P trim exhaust side with there RX7 turbo kits so don't get worried yet. Show a pic of the exhaust side and we can tell you more. By the way, that compressor side on your turbo is capable of 400rwhp on a ported FD.

Thanks alot guys for the input... I will send a picture of the Exhuast side tonite...

Guys tell me if i got a good deal.



I bought this turbo + turbosmart Pro-gate 45mm Wastegate + Manifold + Downpipe



I got this deal for $1000



Did i get a good deal?



The turbo was barely used...

Sounds like a good deal.

Ok just griinded off the flange becuz the outlet which was welded on by the last owner was smaller than i wanted it to be... The flanges outlet was only 2 inches... Now i am welding a 3 inch Pipe....



Also i am attaching some pics of the exhuast side of the turbo... I hope this helps identify... I Measured with a vernier and the exhuast side is approx. 59mm... The pics are from a P-900 hence the bad quality



Is it tooo small??



Thanks

here is a view with the old flange....



I don't get it... why would someone make the outlet smaller would'nt that generate more heat and cause restriction...

Some FeedBack Please!!!

You know they make like...rubber adapters that go from 2'' to 3'' right? @_@



I don't like the idea of grinding and welding, honestly. My turbo's a T3/T4 hybrid, .70AR. I just have a rubber adapter that connects from the compressor housing turbine which is only like 2 inches or whatever to a 3 inch intake piping w/ filter...

i think the exhaust side a/r is .70



will that be too small for a fd??



how much hp should i expect from this turbo at 15psi on my street ported motor??

In my opinion the O trim AR.70 exhaust side is going to offer quick response, but will choke the motor up top. I say max of 325rwhp at 15psi and the motor will not want to rev past 6500rpm's. You would be better off with one size up on the housing and one size up on the wheel (AR.84 P trim).



https://www.nopistons.com/forums/pub...#>/biggrin.png I run 2 x AR.70 O trim exhaust sides on my twin TO4S setup. https://www.nopistons.com/forums/pub...#>/biggrin.png

I am sad https://www.nopistons.com/forums/pub...O_DIR#>/11.gif



I have bought the turbo so will have to live with it for atleast a month...before i can order a new one which will take another month to be delivered .. No i am very very Sad https://www.nopistons.com/forums/pub...O_DIR#>/11.gif https://www.nopistons.com/forums/pub...O_DIR#>/11.gif https://www.nopistons.com/forums/pub...O_DIR#>/11.gif



Also what turbos would fit on this manifold? So that i only have to get a new turbo..



Also how much would this turbo produce at 10psi of boost..



One last question can i run this turbo at 10-12 psi without upgrading my secondary injectors.. i am using stock injectors..



Just have a Power fc...



Oh i know this is the O trim but how do i check if the a/r is .70 or .84?



I have attached a picture of the exhuast side of the turbo in an earlier post... i know the picture is blurred but can anyone make out the A/R?



Thanks alot

The wastegate on my T3/T4 has a stock boost setting of 3 1/2 psi, which is good, because I don't have a boost controller. My question is, what my current set-up, how much boost can I run safely?



I've heard SO many RX-7 owners diss electric fans, and mine is single at that. The temp gauge reads at about 1/3 the entire time. The other problem is, my 5th gear synchro is bad so I'm cruisin at like 3,500rpm in 4th gear just trying to keep up with traffic, i don't want to be pushing so much boost that my car's going to over-heat or anything.



My injectors I found out are stock S4 Turbo II injectors, but they have been blue-printed and balanced which makes them work more efficiently and flow fuel better. I dunno. o_O Help?

Ok, to figure out the AR look inside the turbo to manifold flange, there should be a number stamped into the housing. Pretty much any T4 based turbo will work as far as bolting up to the manifold(to4s,to4r,62-1,T66,T78 etc.), but the real question is how much clearance will there be when mounted to the motor. Yes, you can run stock injectors with that turbo to around 10-12psi with good tuning. I would recommend that you have an upgraded fuel pump.

Alas your predictions are coming true IGY... I just took a run at 12 psi and it felt like choking after 6500 rpms..

Also i had wrapped the dump tube and the pipe from the manifold to the wastegate in glasswool with aluminum to insulate the heat... when i took the car out with the single turbo first time it gave some burning smell and white smoke which scared me but i popped the hood when i got a suitable place to park everything seemed ok... then i kept running 7.5 psi and no smoke.. but today i ran 12 psi for 2 runs and smoke can in from the firewall as i had forgot to put the rubber back in after i brought some wiring in from the engine.. i stopped after 3 mins and everything seemed ok but some burning smell.. what can it be?? does the glasswool doea this the first few time or will it keep doing it forever??



u can see the need for the insulation in the pic in my other post choking up top in the same forum...





thanks

Strange boosting problem..



Ok my car started boosting OK with this turbo under 6500 rpms the power was good.. but then i decided to ditch the midpipe and put in a resonator.. when i did that my car did'nt want to boost over 8psi max.. it would boost to 8 psi at aroun 3500rpms and then drop to 6 psi.. So i put the staright mid pipe back in without the resonator... the problem was still there





I came home and this morning checked to see what the problem could be... I checked the silicon hose from the turbo going to the intercooler was somewhat loose.. I mean if i pulled on it real hard it seemed little loose so i figured it cud be the reason.. So i tighten it.. took the car for a run now it started boosting till 9psi but then the same hesitation at 4500rpms+..



Then i increased the boost from the boost controller and now it would boost to 12psi but then the same thing at 4500rpms... Now it cannot be a boost leak can it.. cuz it does boost to 12psi everytime but starts hesitating at 4500rpms...



How can it be... it was fine 2 days back..



Also since its a right hand drive car the turbo is quite near me.. i can feel when it hesitates that boost is leaking from the silicon hose right off of the turbo..



Please help....
