Okay my car is a 1987 TurboII.
Still has a Series 4 motor, kind of, it has 9.4 compression rotors now with 3mm apex seals.
I will be running a garret T-5 with the biggest damn front mount I have ever seen, it was picked off of a TurboII that came out of the RE amemiya shop, handmade and all. The FMIC is 11 inches tall, 6 inches thick, and 24 inches wide, that's right, it's damn big.
The computer is going to be a Microthech Lt-8.
There are a few details I have not posted because a decision has not ben made yet as the motor is still being pieced together.
Oh and the porting will be a massive street port on the primary(center steel) and bridgeport on the secondary(outer steel).
Boost will be set at 10 pounds for daily and showing, not that it will be a daily driver anyways, and on the track it will see about 16 pounds of boost.
The turbo reaches spool at a rated 2500 rpm on a 13b rotary.
So, the question is, what size injectors should I be using????????????
post your thoughts on this one, I have about 2 months before the motor is ready to run.

A what?

I hate to tell you this, but that it is too thick for a street car. However, if you are building a track-only car that will be at 100-200mph most of the time, then it will work pretty well. Just don't put it in front of your radiator.

That depends on your peak hp and estimated BSFC, and fuel pressure.

Well, I was going to give you a link to the RC Engineering online calculator, but their website seems to be down. Here is the link in case is comes up later:

If not, then you are stuck making the calculations by hand. Here is the information:

For questions about primary/secondary injector sizing and staging, I suggest posting in our Microtech forum.

Boy, what the hell did I stumble into...

First, can you drop the lying?
You can't even get your facts straight, and anyone with a decent grasp of these cars knows it's bullshit.

Just for kicks, I read through the first page of all your posts - very easily done with you click on your screen name on the left...

Lesse...
You post a lot in the 1st gen section.
"GReddy/Trust straight through racing mufflers"???
Shifting the trans mount 2" rear and changing electric fan to pusher to change weight distribution by 2%???
Recommending carbs for a "Killer NA"???

Dude, and that was only the first page!
I didn't even want to go through the other 2...

If you want help, stop feeding us bullshit.
Your lying does not impress me one bit.
You sure you even own a Turbo II?

TurboIIGuy

Wow, you're a jackass, but I'm not here to judge.
Anyway I'm serious, I will post some links to the parts I have with my Fatazz all up in the pix just for you.
And with regards to my other post read the post about carbed N/a, I said to be cheap, and fast as N/a, the guy I posted to was on a budget. What I guess you would tell him to go out and spend a grand on a microtech right, when he's on a budget.
Anyway back to my question, I'm not here to get flamed up.
This is really going to be my setup, I blew up my TurboII just over a year ago and I have been buying things here and there as I come along them.
The intercooler is pretty wicked, it's made with 4 cores, I have a pic I will post it.
As for the turbocharger I just barely picked it up.
I am having a buddy that just opened a shop up do the block for me but his recommendation as far as secondaries goes is to use 1600cc. That sounds excessive espescially since they will probably never see more than 60% cycle, right?
Oh yeah and I have been posting alot in the 1st gen sections, because my 2nd gen is out of commission, duh. I have two 1st gens and two 2nd gens, here are some pix.
oh the pix of my turboII need to be updated, it is no longer on those crappy chrome wheels it came with that are in the pix.
the white car is a 1988 GTU, that's the one with the Trust straight thru mufflers, if that's not to hard for you to believe.

The black 1st gens have already been sold, the burgandy one in this next pic I bought cuz it had Enkei wheels.

here's the intercooler,

that's a 6.5 inch speaker in front to give some contrast of size.
I'll post pix of the turbo later tonight.
I got the intercooler from aerodyne industries in Garden Grove, they bought a front clip and parted it out.
Okay so back to my question if anyones cares to be helpful and stop beig so ****.
what size injectors should I use, or could I use??????????
Keep in mind that it of coursde will not be driven anything mor than maybe a couple times a month and I would like to take it to LACR and Pomona now and then to give it a pass at the track.

Yeah I know Garret doesn't doe the T thing with turbos but the guy I got it from siad it's the size of a T-05 so I will post the specs on the turbo with some pix later on.
Okay what the heck is BSFC??????
I already posted in the microtech forum, thanx.

Evil Aviator

Anybody who gives you an answer is taking a wild guess unless they know the values that I already posted, which you do not seem to know yourself. If it makes you feel better, I think you need 23 each 280.666cc/min@3bar injectors. Happy now?

So what is a T-05 turbo?

Brake Specific Fuel Consumption. For a turbocharged RX-7, you are looking at somewhere around 0.64 to 0.80. Generally, the more rich your mixture and/or the more boost, the higher the number.

That intercooler monstrosity is not even remotely suited for drag racing, and your car looks too nice to be a dedicated racer. The intercooler will heat soak like crazy while sitting on the line, it will block off your radiator, and it will not even become moderately effective until the very end of your run, if at all. However, you can still salvage your effort by cutting the intercoolers apart, and making new end tanks for one of them. This should be about perfect. Then you can sell the other core to recover some of your refabrication costs.

I will be running a 720/1680 setup next week. Seems like everyone already has maps built for this setup to run as baselines. Yeah you might have to cut the entire front end out to get that intercooler in. Better get a reverse scoop hood to vent the rad heat or you wont be racing long

TurboIIGuy

Well my car is not specifically purpose built yet, the point of the project is to make massive power. I am looking to pick up a sponsor with a company a friend of mine works for. I need to have a car that is making some serious power before they pay out for a JGTC style body or something. This is a turn around from the original setup I was going to run with a T-60-1, it would have given me about 400 to the wheels or so, anyways I was told. The car was just going to be powerful and streetable but now we are looking to be insanely over powered and showable at some drift events and high power race days. I want to be rubbing shoulders with some supras. Back to the intercooler now, as I said it came of of a RE amemiya front clip, the car had a turbo just slightly larger then the one I will be using, it was set to boost at 18psi, and it was a road race car. The shop I got it from said the car was probably making over 600hp. If you can see it in the pix, the intercooler is made up of 4 smaller cores. Two are stacked in front then about a 1 inch gap then the other two. The front clip had a couple of things removed from it when it was shipped and we were trying to figure out if there was a cooler in the middle of the intercooler or not. It looked like there was something, maybe a water spray or Co2. As you can tell I don't know much about calculating specifics when it comes to all this computer controlled fuel infector crap but, that's why I'm here asking the questions. I know how to build a motor and make it fast but I use carbs, it's pre-historic but it's simple and effective. I like the look of nothing under the hood but a short block, intake manifold, carb, and headers. So yeah excuse me if I seem a little lost with this stuff it's because I am.

TurboIIGuy

oh and the intercooler was designed to be mounted with the bolts that hold thehood latch in place, it's fits perfectly in the front of the FC.

RETed

Lesse...Killer NA on a budget?
Um, ok...


That intercooler looks like four stock FC oil coolers welded together...
Do the words "ghetto" mean anything to you?

You need to go read up on fuel injectors and fuel injection control.
Hey, I'll throw you a hint here...it's better to have too much fuel injector (capacity) rather than not enough.
What are you trying to do?
Hit 100% on the nose?


You said Trust/GReddy straight through *RACING* mufflers.
There is no such thing.
Do you have proof otherwise?


In your opening post, you said "24 inches wide".
Most of us who quote intercooler dimensions only meaasure core size.
We really don't care about the end tanks or inlet and outlet dimensions unless we're talking fitment.
We're talking performnace here, right?
Or you're trying to impress us with your bling-bling JDM parts, right?

Well, I hope you didn't pay more than $100 for that intercooler, because it isn't worth much more than that.
It's four small cores welded together.
Without better pics I can't tell if it's four stock IC cores (which is most likely) or four aftermarket IC cores.
Bottom line, it's a very cheap method to try and get a big intercooler core.
It doesn't impress me.
Flow efficiency is inferior to a properly sized single IC core...see below.

I'd like to know what a Garrett T-05 is too?

RETed

Wow, you have been doing some reading!

So 400hp at the wheels is not enough?
How much HP is "insanely over powered"?


Road race RX-7's from Japan making over 500hp is very rare.
We're talking about someone's super secret project or an ex-shop vehicle.
If this was a real R.E.A track car, their vehicles rarely go over 500hp with a 13B.

You mentioned talking about drag racing in your previous post.
Why not go A2W IC?

Wow you are just annoying aren't you. Do you get of on being so annoying????
Anyway, as for the intercooler yeah it does look like 4 oil coolers but it's not, they clearly have a different design and it did come off of a RE car i saw the clip myself. RE amemiya does some "ghetto" stuff themselves, just look at the FC upgrades they have available, the Stage 1 intercooler upgrade is mearly a stock top mount with the end cut off and half of another top mount welded on to make it 50% larger, that is ghetto and that's the kind of stuff they sell and people buy it becuase it's RE. Get Over It!.
And you say the intercooler doesn't impress you, who cares, I sure don't. How self centerd to think that someone on this forum is tryign to impress you, what a joke you are!!
You want to bash on the stuff I'm posting becuase it's what I have but I don't see you trying to put your set up on blast, what R u Running???
I am almost tempted to pull out my RX2 and put it down on the track.
But what ever you just want to talk trash and think that people are trying to impress you, that's perverted and distorted.
If you don't want to be a productive par tof a thread get out.
I want technical assistance you just want attention.

TurboIIGuy

if you can break traction in 5th gear by flooring it then you are insanely overpowered. No 400hp is not enough when you've seen the cars around here that I have.

RETed

Ah, that pretty much says it all.
You might say one thing, but your replies are saying another...
Good luck with your project.
BTW, you want to see what I'm running, the link is in the .sig...

Post up some pics of the RX-2 while you are at it

alphaxxn

fifth gear? What are you talking about? With the budget you supposedly have with all the cars over there you have enough to get a 6 or 7 speed custom mated for the 13bt im sure.

White_FC

TurboIIGuy, I have done some research on this matter and I have found a much cheaper route for you to take.

It has been proved that by reducing the softness of your tires and their contact patch with the ground the effects on traction are quite similar to having more power with the same hardness and level on contact patch.

Might I suggest buying some cheap, smaller tires and leaving them in the sun for a year or two and then trying this experiment again.

Regards, Nathan.

That makes sense. Like I have been telling you, that intercooler is only for a high-speed road race car that does not drag race or drive in traffic. Yes, the intercooler is ghetto, but you can convert it to something that is actually useful for your purposes. Stacking one intercooler on another works, but stacking one behind the other is big trouble. As is, that intercooler will most likely REDUCE performance vs. the stock TII intercooler. Here is how to convert it:

1) Cut off the upper pipe and supports.
2) Cut the end tanks and any braces so that you end up with a separate front and rear half. You could also completely cut off the end tanks, but I have a feeling that you would be better off leaving as much as possible on there given your limited budget.
3) (Not Shown) Fabricate new end tank plates out of aluminum, trying to use the same grade of aluminum as the intercooler cores. Cut part of the old upper pipe to fit the new end tank. Try not to use any bends if possible. Each bend in your system between the turbo and intake manifold reduces boost. TIG weld the new pieces in place. If you don't know how to TIG weld, then just make the plates fit as well as you can, and take it to a good weld shop.
4) Sell the other half of the intercooler to one of your low-budget racing buddies to cover the cost of the welding.
