I found out from Soloracer(Eric) that I bought one of you turbo's yesterday, he's good at spending money, even when its not his ..
I had been shopping for a turbo awhile, this is going on my TII with 3mm engine, since you had these turbo's what was the setup you were anticipating to run with these?
Eric currently has an HKS undivided intake, I copied it and was ready to weld it all together last night when I got the call from Eric that he had decided to buy your turbo's that were divided inlet, I think an undivided manifold would work with a divided turbo, but the center dividing plate would erode quickly, do you agree? and also the lose the benefits of the divided housing(ie:quicker spool)?
Do you have a map for these turbo's?
I was originally set to buy a wolf 3d, although with the impending release of the Greddy e-manage I was looking at that route, as I like the aspect of the stock ecu maintaining its idle control, and only manipulating the on boost fuel and igntion maps, I currently have a version 1 s-afc, the other option is to go with an ITC and a Rebic iv AIC, however then I have now means of datalogging, inejectors were going to be upp to 720cc secondaries this winter, is this enough with that turbo would the 1200 or 1600 cc's be more appropriate?
I am going with a walbro fuel pump, other plans include a new intercooler, I may splurge for a greddy or whatever kit, but I would like to go the used route if that could save me some coin, I have my doubts about the volvo being an efficient enough core for this application, I would think something bigger is going to be needed, any ideas?
One more thing, had you investigated the oil lines, and what is needed to hook them up? I can do it once I see how the turbo fits, but if you have done any prior engineering here, I would be interested to know.....
Thanks.....Max

i can answer some of em. i talk with chris alot. i believe he bought em for resale, since he's authorized to sell garrett/turbonetics.

if your talking about the hks un-divided manifold then yes im pretty sure it will be fine. chris used to run that manifold and so did his other buddy also 13b ace runs a t78 on this manifold and many others on this board. i don't think you will run into any other problems, besides some slightly slower spool up, which won't be all that noticeable cause it's not like you have a t88

your only other route though would be a custom divided manifold which im sure you know the price of those $500 and up

turbonetics has a map of these turbos on thier site:
http://www.turboneticsinc.com
turbonetics are garrett turbo's re-badged if you already didn't know? and im pretty sure it will be the same specs etc.

as far as the other stuff, i'll let chris answer that. as i have not had the pleasure to install one till a few months but i will tell you 720cc secondaries will not be enough. at 10psi you will be making around 350hp. there is a couple of good threads in this section that have some good recommendations on fuel for this particular set-up

*waits for chris to step in anytime*

Thanks for the info, I can go divided/undivided right now, as I can biuld my own manifolds, Eric already has the HKS undivided so he would most likely want to use that if he could... I was surfing around some injector sizing sites , it looks like its gonna be 550 primaries with 4 720 cc secondaries/aic's, I thought my mileage was bad now .. its gonna bite after this...
I keep seeing referrals to an "NPR" intercooler, got any info on this unit and what its from?
I am looking for some info on the ITC from Apexi, is it capable of retarding both the trailing and leading igntion or just the leading?? Max

RX-7 GT

i don't know much about the npr, its from those ugly looking izusu npr trucks. the stubby nosed ones

there is 2 different versions. im not sure on the dimensions, but i do know the bigger one is like the size of the stock radiator HUGE and requires some cutting here and there to fit it in. they float on partstrader now and then. i would think the smaller npr would be sufficient, its about the same width of the big one just smaller, around 8-10" high? maybe 18-20" wide?

as far as the apexi itc, you might want to go with the msd or crane hi-6 unit i think its called. those are more common among modified rotory users.

if you go to chris's site, he still has his old setup listed along with what he used:

http://www.geocities.com/initiald_fc3s/chris.html

he used though i believe 550primaries/secondaries and then 4 additonal 720's plumbed in the uim. and he was almost maxed out on fuel and running higher boost. also don't forget to get a new fuel pump, supra or cosmo would be sufficient.

Max my man! What's up? Checking up on me? I'm beginning to think you don't you trust me. Might just hurt my feelings. Just wait until you see what else "we're" buying... just keep that RX7 upgrade account full of the green stuff and I'll make sure it gets spent. After all, you can't take it with you.

I was looking at orderiing a T04B from TEC out of Colorado and asked them many questions in the process. One was regarding running a divided turbo on an undivided manifold. They felt that with the EGT's a rotary puts out that you might end up eroding the dividing wall and sucking in small pieces of metal. Not something I really want to do so it looks like either a swap of the housing or a different manifold.

I know John D. runs (or used to run) eight 550 cc injectors as does Ryan on the board here. I might do the same or buy another set of 720's and go with 4 550's and 4 720's or maybe just go with 550 primaries, 720 secondaries and 720 additional injectors. It all depends upon what is needed I guess. I still have to get a fuel pressure gauge to see what my Malpassi unit is up. I suspect it's set too high and accounting for a lot of my rich running problems. Not that I really dislike 5 ft flames that last for 10 seconds but I do find it really makes for expensive driving when one can't drive 30 minutes without filling up.

I can't wait to get the new turbo as well and get started on this project. Going to have to get "Objects in mirror are losing" decals made up for the sice mirrors after this round of mods.

Hey buddy,
Yes I also hear about the wall in the turbine housing corroding, but my one buddy ran this setup and had great results with his turbo II. Well not this turbo, but a 1.00 divided on a hks manifold.
As for fuel he was running 2 additional 720s and they limited him to 10psi of boost, not enough fuel, maybe larger pump could have helped in the mix, but id like to make sure to have enough injectors...
The 8 550s setup is probably the best all around setup for turbo II's with aic's...
I never really mess with the ITC so i cant tell you too much there.
The AFC does well, but only for small bolt on applications to smooth everthing out.
Let me know of any other questions...

When spending this kind of money, I think I will play it safe and go with the divided manifold since I have the option to at this point, I marked out and cut a new divided flange so I will have the manifold finished tonight or tomorrow, depending on afterwork energy factor. I thought of perhaps knife edging the center turbo wall to minimize the gas impingement on it, however this may lead to quicker corrosion, with a 1.15 a/r though I think a divided is the way to go...
Greddy couldn't tell me anymore about the E-manage today, except that the j-spec version is available for the TII, so most likely it will be here to... The injector issue is going to be where making a decision is tough, the e-manage will support 2 ai's so perhaps a couple of 1200'ss for the ai's would be appropriate, but then again I have doubts that my motor will hold together at anything over 400rwhp..
I guess if Eric decides to part with his older wolf, I will buy it from him, if he's gonna upgrade..
The intercooler question is a big if to, but I think I will concentrate my efforts on finding one from a Dodge cummins, its big, and flows alot.. Max

SoloRacer

Max,

Did I ever tell you that a friend of mine went to Australia for two years and that I visited him last year? Well, it turns out he is heading back this way this month sometime. I tried to e-mail him but no response yet. I might see if I can get him to pick up a new Wolf for me and bring it home with him. Anything else you might want from over there? Perhaps a BOV?

Dodge cummins intercooler eh? I have a picture of an NPR intercooler that was for sale on E-Bay. Looks pretty good actually and might fit pretty well. It even appears to have aluminum end tanks with 2.5 inch inlet and outlet.

Hmmmm taking a black box with wires sticking out of it on an airplane in this day in age could be a risky manouever, he may end up getting a free proctology appointment if he does that..
I wonder what they have over there for wastegates and such, our dollar is slightly stronger than theirs so there could be some savings to be had, sucks being Canadian sometimes eh?...
I forgot to add last post that I found a guy with a laser cutter for steel plate, he sounds pretty reasonable so I am gonna take him a scan of the flanges and see how if he can cut them out of stainless for me, if so, I will do the manifolds in stainless if the mild steel one works out ok performance wise, I am thinking of joining the tubes together at one point so that the waste gate vents both ports, instead of just one, but doing it in a manner that the pulses don't mix. I should wait till I get the turbo here though, strip my car down, and then biuld the final manifold, as I am not sure if the HKS gives the best turbo placement, I notice some of the other manifolds move them forward quite a bit, I want to keep the turbo as low as possible, and away from the intake. I am gonna have to call in all my "trade" favours to do this project, but I am sure I can get everything done pretty cheaply as far as piping, bending, and cutting goes, but most of it I can do myself.. I am thinking of using thin wall standard pipe for the intercooler connections and powdercoating it, rather than the aluminium pipe, as I have the capabilities at this time to work with steel more so than aluminium..
Can you send me the pic of that intercooler Eric? I would like to see it.. The hard part for me is going to be keeping the powersteering,a/c and battery in their original locations, you'r not going to have those problems though...Max

NPR Intercooler on E-Bay

it's currently going for more than I would like but maybe we can find one local. What does it come out of again?

RX-7 GT

Izusu NPR's, stubby commercial trucks.

SoloRacer

Heres another site with intercoolers and a better picture of the NPR unit. It's a dodge site....Max you probably already have the link.

Yah got that link already... I am gonna look at a HINO intercooler tomorrow, its near a place I have to work at so I though i would go have a look, they want 250 per core, not bad if its decent..
I can't remember if we were told what size the exhaust outlet is for these things, I think a stainless downpipe would be a nice touch, I should get an EGT guage to install at the sametime I guess, this is gonna work out kinda cool, I will have all the needed parts leftover to turbo my GX afterwards, injectors, Map, turbo, manifold, downpipe etc, two for the price of one, excellent!!

SOLORACER...

I remember you saying you have an HKS manifold for your car but your going divided manifold correct? I really need to get that HKS manifold from you if you still have it and are selling it, let me know on my email if you have it, i can paypal you for it tonight, and need it shipped 3 day or sooner. I gave you a good deal on those turbos so help me out pleeease , Thanks alot.

SoloRacer

Chris,

Yes I have a cast T04 HKS manifold brand new that has never been installed. I bought it anticipating I would need on for an eventual upgrade. I've got to ask Max about the manifold as I think he was considering using it for one of his other cars or possibly using it as a template to build a divided manifold. I paid a little over $500 Canadian for it after all taxes, etc. That works out to around $320 US. I know you can get them down there for $250 US but bringing them into Canada adds a shitload of taxes, etc. Sometimes it just sucks living north of the border. Rather than sell it to you I could be talked into trading for it. Both Max and I need good wastegates and BOV's. We also need Walbro fuel pumps and I personally would like to get a good electronic boost controller. Do you have any of these items at your shop in good condition that you would be willing to trade?

SoloRacer

Chris,

Ever since the @home service (my e-mail provider) has gone into bankruptcy I'm not certain I'm getting all my e-mails. I'll be switching to a @shaw.ca account soon though. I sent you a message asking if you shipped the turbo's yet but I'm not sure if you got it or not. Drop me a PM here if you are having trouble getting in touch with me.

Thanks.

SoloRacer

Chris (aka. Initial D FC) I've called, left messages and I've e-mailed. I've left you my e-mail both at work, at home and my home phone numbers. So far no reply as to shipping of the T04 turbos that have been PAID for in full. I've seen you posting on the list the last while so I know you are around. So either I have to assume that:

A) You are not getting your phone messages or e-mail messages. Or you are and don't want to talk with me.

or

b) You just scammed me out of some major dollars for turbos that you do not have.

So which is it? I have been waiting for almost 2 weeks for you to ship and so far all I have is excuses. I even offered to pay for 1/2 the shipping.

Maxthe7man

I hope this turns out ok, if it does, I will be a happy guy, if it doesn't I will be an angry guy....I guess its the waiting game now though....Max
