Ok guys, I've decided to go single turbo. I know I know, but this is what I want to end up with so why not just go for it right. Anyway, I got my Turbonetics T72 today and I was supposed to get a .96 A/R exhaust housing but I got a .81 instead. I really don't want to go throught the hassel of getting the .96 unless its a significant difference. What do You guys think.

The .81 will probably make it spool faster I just hope not too fast. I dont want to peak out too soon in a pull. I'm sure you know that its going on a 3 rotor but the exhaust isn't street ported not that it makes that much of a difference. Anyway let me know.

Here is a picture of it. Well, maybe not. Hey, with all of the traffic that this server gets has anybody thought of upgrading it. I can't even post a picture and to surf through this thing is a real struggle

God, this is the 5th time I've just tried to post these words and I cant even do that. Well, I guess I'll just read whats posted and drive on.

 

i would be tempted to get it running with the turbo you have and swap later if you dont like it

mike

 

Yeah I hear you. I know I can get it to run but its going to be a wiring nightmare. The ECU will have to go on the left side of the car instead of the right which makes things a real pain in the ***.

if you move the firewall boot the ecu can live in the stock location, i had mine test fit that way

mike

 

There is really no point to argue because I am going single turbo but the coil wiring is too short and will not reach the ECU if its in the stock location. Plus I dont have a MAF sensor which I could probably use a 91 turbo II but what the point I want to increase the air intake not hinder it. Also making sure all of the necessary grounds are hooked up right and combining the 91 stock wiring with the cosmo is far from easy although I have already mapped it out and it can be done. The coil wiring could also be extended to reach the ECU and some resistors could be used to fool the ecu into thinking it has a MAF. I'm not saying it cant be done I know it can, but my overall goal was to have a single turbo setup the twin turbo was just going to be temporary. So there you go.

Any new pulls on the 3 rotor. Got any updated numbers for us j9fd3s. How strong does the car feel and how is the drive train holding up.

 

By the way why cant I use a custom avatar.

 

ive actually gotten serious about getting it to run right, and i've been playing with it for a while. so its actually running pretty well now, it feels strong now too. the next step is to tune it for power. the drive train is holding up really well, no problems at all.

mike

 

Because it's going to cost a small fortune for all the "other" parts like FMIC, BOV, custom manifold, upgraded fuel system, etc., and then another fortune to build the drivetrain to handle the extra power, not to mention the fender flares or wide body kit needed to clear the required larger wheels and tires. I recommend getting the car running on the stock twins first. I really wish that I did this.

I don't know. I'm going to try out a .96 on my T66 and see how it works, although I have a feeling that it will be too small. It's difficult to get good info about AR's for 20B turbos because so few people have experience with them, and any drag racing information is pretty much worthless for my application.

You need 100 posts to get a custom avatar. Start posting, nubie.

 

HaHa, I was waiting for the wise Evil Avatar to post. How have you been anyway?
I know I've crossed over to the single turbo world. But I'm going to see how the stock drive train holds up because I'm not going to be drag racing it, it should be good for a while anyway. There is a guy I'm sure you have seen him thats running a 20B in a 3rd gen, with T-66 and the stock drive train with no problems so far. He's not running it too hard though.

Well let me give you a price break down so far, You kow what I've spent so far.

Intercooler: Spearco 3.5"X19.5"X11.5 $600 new
Turbo: Turbonetics T-72 Polished, w/ Q trim $1130 new
Wastegate: HKS GT 60mm $350 used
Injectors: 3 x 550 Stock (have already), 3 x 1680 $195 almost new
Fuel Pump: Aeromotive 11101 Good for 800+ HP $250 new
Clutch: ACT Extreme PP w/ Street/ Strip disk and 9.5 lb aluminium flywheel $915 new
ECU: Microtech LTX 12 w/ 6 coils, laptop doggle, handset, loom, 3 bar upgrade...... $1310 new
Suspension: JIC FLT-A2 Almost new $920

That makes $5670 add in the $5410 that I have previously spent and the total is now $11,080. Now I need to get some custom stuff made which the guy said he could do for about $1,000 plus or minus. And I'll have a car for about $13,000 that is pretty awesome.

 

13k isnt bad at all. just go get it done


mike

 

Boy, I see a lot of "little things" missing.&nbsp You know what they say..."double your planned budget and that's your actual cost".&nbsp $22k sounds about right. *grin*

-Ted

 

I said the same thing once already. Now I'm saying it a second time

 

Thats alright just dont hate me when I do it for that. I actually know that that is going to be the price its just not all put together yet, but you will all know soon enough.

 

I thought it was triple it...

And we're not trying to disuade you...just telling you the final number after you get most of the work done, not simply getting the motor into the car and running. There's tuning time, fuel lines (cost/install), suspension, wheels/tires/offset, gauges/install, wiring, battery relocation/install, etc, etc.

I'm sure I wasn't the only one to think it was possible for under $20K... ha ha!!! Good luck to you sir as you'll need it or have a truly magnificant garage and equipment to use on your own time.

 

I now have my 84 RX-7 dialed in very well thanks to a lot of help from my friends. Now I just need to work on adjusting that loose nut behind the steering wheel, lol.

Oh boy, you forgot a lot of things in your expense sheet, but you will figure that out in due time.

You may want to verify that clutch. As far as I know, ACT doesn't make an SS disk for the TII. If you actually have the 00 disk, note that it is only rated for 443 lb-ft torque.

 

Hey Turbo 3, Thanks for the added input. I have already taken those things into account, and I have done most of myseld already. Battery relocation is done, fuel lines and sittings I can get really cheap through a friend and I know how to install that too. Suspension I already have and I'm going to install it today actually, its a JIC FLT-A2 suspension. But I got it at a good price at only $920 and that was already in my price quote above. I bought a set of Mitec 17's from a buddy of mine that was hurting for money for $200 with 235's up front and 275's in the rear. Guages and install I had previously and I'll install it myself.
The way that I save money is I look around for deals I don't jsut run to the store and pay retail for everything that would get way too expensive. I also try and do as much work as I can on my own.

just go do it, its possible

mike

 

Well, thats the best advice I've heard so far. You will be glad to know I'm doing just that. She is out of her cage and on her way to the guy doing the custom work. Suspension went on really nice and looks great. Oh, almost forgot I put a hood on it too a N/A one at that so if anyone wants to use one it will work just need to do a little cutting as you will see.

Now for some pics,

This is going to take forever. Please upgrade this server or something it is crawling.

Here you can see where I had to cut in order to make the hood close.
