TO4R Finally Finished...lots of (huge) pics...not 56k friendly!!!
 

Ok so it is done. The car went under the knife two weeks ago today and was started for the first time today. I built this kit myself and did all the work other than downpipe in my garage. I don't have an air filter yet (ordered it last week, should be here tomm or monday). Car is not yet tuned, going to Rotorsports Racing next week.

Here are the specs of my kit...

-Garrett TO4R with .84 A/R and P-Trim Wheel (fully divided)
-Polished Comressor Housing
-HPC Coated Turbine Housing
-V-Band Discharge
-Wet Center Section
-HKS Cast Manifold (divided)
-HKS 50mm Racing Wastegate
-HKS Racing Bypass Valve
-Wastegate Dumped to Atmosphere

And now for the pictures...well some of them....the rest can be viewed at...

Looks real nice, I like it. ;) Keep us posted on the numbers.

Dammit!! ANOTHER car done before mine!


Looks great!

hows it feel? power wise

where and how much for the turbo? do you have exact dimensions on the comp wheel?

Haven't driven it yet, because no filter (came in yesterday) and no tuning, but I will post later when I really feel it.

Got the turbo from www.cheapturbo.com

These are great people to work with. The turbo costs 950, then the polishing is 60, then HPS is 60, then V-Band welding is 40, then V-Band Discharge kit is 115, and wet center section is 75. So the turbo all came out to be about 1300 and I had it in about two weeks after I ordered it. They also have TO4S, TO4E, T66, etc.

The turbo has a 66.5mm inducer, 102mm inlet, and .70 A/R Compressor Housing. Hope that answers your questoin.

Looks great!
Another single turbo FD on the road.
I need to get mine done. :(

what turbo manifold is that?

Re: TO4R Finally Finished...lots of (huge) pics...not 56k friendly!!!
 

I thought they were all non-divided.

Well I got the HKS Manifold Part No. off of there website and gave it to a shop who sells HKS parts (not FD parts but they can get them). A week later I had my manifold, divided.

M-P

looks good. Me and garrett just put our motors in last week. still breaking mine in. i went for a 2 hour drive tonight, everything feels smooth as butter. Hey man your from hickory. another single in NC. We should definately meet up.

Jay

Yea man we should definately meet up sometime. Good to here yours is running good. Got to get mine running properly and then tuned this week.

Alright just got the pics taken of the Airfilter installed. It is an S&B Power Stack Filter, 4" Inlet, 6" Length. Mounted on a 4" steel elbow that I also cut today. Filter is a little larger than expected. I should have no flow issues.

MP, the car looks beautiful. I highly recommend RotorSports, however they do not have a dyno to tune your car. I'm not sure if there is even a dyno close to them as they are a bit out in the sticks. If they will be dyno tuning the car, i would recommend bringing the car to www.undergroundracing.com in Charlotte, NC. If they are going to tune the car on the road, then nevermind :)

Darril

What they are planning on doing right now is tuning it on the road and are going to put together a big dyno tuning day for some 7's and then going to fine tune it then. They haven't decided when this day will be. But yea, Brian and Rusty at Rotorsports are great guys. They tuned it when I put the 1600's in and went nonsequential in May.

Thanks for the website on that dyno place.

M-P

Agreed. Rusty and Brian are upstanding people. The shop is really in the sticks. I wonder if they can safely stretch your cars legs when tuning it. Best of luck and please keep us updated on the tuning.

Darril

damn, i cant wait to get my single project completed! looks good though...:rock:

Yeah, I've been dealing with Bryan for around 2 years now. He's helped me out in when my car has been at its worst. Usually after I've had my hands on it.

I think I'll contact him about dyno day and we can compare and contrast between the different set-ups.

thats a fucken nice turbo

Well I just picked it up from being tuned today and all I can say is....best thing to ever happen to the car. I was hoping for 15 psi, but it seems that since my motor is not doing well on compression (60psi average on front, 68psi average on back) that it won't boost past 13psi. Although it does have full 12-13 psi before 4000 rpm and has 8psi by 3300 or so. I am getting the mazdaspeed team support guy next month, so I will be able to buy my motor and build it (street port) for relatively cheap for this summer, then hit a good 16-17 psi.

It should be dyno'd in the next few weeks. Possibly a dyno day with Rotorsports Racing and some other people from NC with single turbos.

Just curious if the HKS cast divided cost the same as the collected?

Why is there a notch cut into the divider in the manifold???


-Ted

I don't even really know how to get the collected or the divided. I wasn't sure as to which it was, just kind of got the part number off of their website. They don't designate between the two.

Here is what I got off the website:
17141-130327 MAZDA RX-7 1993-1996 Turbo ; Engine Code: 13B REW - Fits Standard or Racing Wastegate

I asked the same question to someone and they said that it was to equalize pressure between the two channels. Not sure if they are right but it sounded about right.

M-P

Uh, who the hell told you that???

That stupid cut just basically waste about $500 you paid for the turbo exhaust manifold, cause you could've bought a collected version for under $300.



-Ted

so one small cut, that seems to be part of the design, in my divided manifold make it no better than a fully collected manifold. I think not, but I do agree it would be better without the cut, but it just couldn't be as bad as collected.

No, that cut isn't stock.  The HKS manifolds do not come with that small notch in the divider unless they suddenly changed their design within the past year or so.

You need to brush up on the collected versus divided debate in terms of exhaust design.  That notch pretty much obliterated the advantage of the full divided exhaust design, and the putz who cut that out should be taken out and shot.


-Ted

I agree 100%. That cut is a bad thing, but no were near as bad as the LOG style collected manifolds.

I also agree 100%...lol

~Mike............

Wow i didn't realize it was that bad. The thing is that it wasn't cut by someone after casting, that cut is part of the cast. Their are no scratches or cutting marks. The cut has the same consistancy with the reast of the manifold. Oh well whats done is done. It still feels great and Im still smiling. I will know better next time.

Thanks guys,
M-P

Any news from the dyno yet??

I am still waiting on a dyno date. Some guys are trying to put it together now. Shouldn't be much longer and if they think it will be a while I will just go on my own, cause I really want to know.

Sweet, I would really look at the dyno in Charlotte. That's my home town. I lived in Charleston, SC for the last 5 years as well. All of you FD guys from Charlotte and the area need to hook up with the SC crew. We are a very very close group and we're always looking to meet more rotorheads. PM me if there's anything I can do for you.

Zach

i am looking to buy that same turbo. can you list a breakdown of all the parts that you used because you didnt get the kit and how much it costs??

Thats alot cheaper than even the xs TO4E kit now isn't it:D

Any other info needed just ask.

thats really cheap. my firend bought turbo's from cheapturbo.com for his 3000GT VR4 and he said they have great prices and service.

but how much did you have to spend on the setup overall? i mean with the pfc and the fuel system and everything because i heard it takes a good $5-8k to go single. is this true?

Yea, Here is the rest of the stuff. May have a few small things missing here and there, but here goes nothing. I did the Fuel last May and the ECU and Intercooler the November before that. So I have been preparing for single turbo ever since I got the car pretty much.

at www.rx7store.net
Apex'i Power FC w/ Commander $1250
RX7 Store Extreme Fuel System $850
ACT Xtreme Street Clutch $505 (traded my stock seats for it)
Apex'i AVC-R $450

or
Greddy FMIC $899 or $1250 (piping to twins or single)
Block Off Plate Kit $65 (made my own cheap ones though)
PWR Radiator $419
Pettit AST $149

at www.rx7.com
RP Triple Pulley Kit for Airpump removal $350

other parts from random places
HKS Racing Bypass Valve $200
Rotorsports Racing Plug wires $80

That is a total of $6244 for the all the supporting mods if your car is about bone stock other than exhaust.

So grand total with turbo and all is.......alot.......$9029

I am sure alot of people would already have some of the mods listed, but that is a total price. Does not include any engine work though. My next step. Buying a core for a rebuild and large streetporting. Then I will be set for life. Haha, probably not.

M-P

After doin a extensive 2 day search for a good, full picture of the engine bay of a FD that had any sort of the XS T04anything turbo upgrade, I am sad to say I have turned up empty handed. I saw the ones that he posted but I am lookin for a kinda full engine bay pic. And i kinda wanted a pic of the XS T04S installed if possible. Can anyone help me?

So the big question..

What is the real difference between the $950 T04R and the $3000 HKS one?

Well not a whole lot other than there are a few things that HKS has custom spec from Garrett made specifically for them and noone else. But this is not enough to justify the price being 3x more. Also I believe that the back side of the HKS turbo is not a v-band flange but a bolt on one instead. I say save yourself the 2000 dollars from the HKS kit and just go with the kit I pieced together. I'm sure there is more performance with the HKS kit, but not $2000 more. Although it does use their stainless manifold and S/S wastegate compared to my cast iron of each. But you just have to add 400 to the price of my kit and get the same thing.

M-P

Still no dyno sheets??

Sorry but no dyno numbers yet. I have been really busy with school and what not, but I will have some numbers soon.

whats so bad about the iron manifold?

RUST

HEAVY

THERMAL EXPENSION

I am hoping to see some good news from the dyno soon. Still nothing 0110??

Zach

really nice , that manifold is a great piece to bad about the notch though ,....oh well at least you will never have manifold cracks ,...also you have a microswich an youre throttle-body is that nitrous???

need......dyno....need......numbers.....when do you think you'll have it dynoed? what are you looking at hp wise? i have a .96 t04R on a streetport, and im kinda using your setup to judge....good luck

0110-m-p, "From muffler shop
Get downpipe, dump pipe, and IC pipe made....$150"
I currently need to do this. How did you go about it. I mean they didn't have your car right there to work on, correct? How did you give them the info they needed to built , say the DP, so that it lined up pefectly with your midpipe? Thanks
