I'm getting ready to convert my FD to single. My goal is a powerful, comfortable(A/C and P/S) STREET car with the occasional tank full of c16 at the track(or maybe the street). I've searched alot and looked at alot of other setups and advise so here is my proposed setup:

-Fresh Rebuild with 2mm seals and medium port
-Where to get silicone seals and viton o rings?
-XS T04S
-Cast manifold or SFP Custom tubular?
-850 primaries and 1600 secondaries->custom rails
-SX FRP
-Twin Supra TT fuel pumps
-TEC III or PFC w/Datalog???????????
-Jacobs ignition if I go with PFC

How does this look? I already have the turbo itself. I'm just looking for opinions on the overall setup. I'm still deciding between the TEC3 and PFC w/datalog. I'm just wondering if the TEC3 is overkill for my setup. I'm shooting for around 400 SAFE rwhp on pump gas, which other forum members have already acheived, so I know that this is doable. Thing is not too many have gone further than that. Most are using the Power FC.

I'd like to put down SAFE 500 rwhp on c16 and 20+psi. (Cruser did close to this but he was tuned pretty lean.)That is where I'm questioning the EMS. I know the TEC3 can handle this no problem, but what about the PFC? I know I'll need a datalogit and 3 bar map sensor if I go this route.

I'm looking at TEC3 since it has the ignition setup and all that good **** already included AND I can get it for $1800. How reliable/streetable is a stand alone though?


Thanks for the help in advance.

Don't forget your intercooler and your wastegate. But overall it looks like a good setup. I don't know if dual Supra TT pumps are needed though because just one should support 500rwhp.

Personally I haven't heard too many good things about tuning PFC's with Single's but its up to you. I don't know much about TEC3 other than PFS supports it I think. You might want to consider Haltech. Up to you though.

 

Already have the front mount on the car. Forgot to put the wastegate on the list.

If I go with TEC3 PFS will be doing the install and tuning

 

I was recomended not to use the jacobs becuase it buns up stock coils.. A heavy streetport would also be better for that turbo I would think, wouldnt it?? And also you might be ok with just 1600 sec inj.. as far as the rest you should be good. Get some fine tunning done becuase you wont have as many chances with those 2mm then 3mm, but if you blow a motor with the 2mm it will be alot cheaper to rebiuld.

 

I'm now leaning towards the TEC3 because of the shitty Jacobs setup with the PFC.

Any thoughts on the rest of the setup?

I know that 1600's MAY be enough but I'd rather be safe and go with 850's also.

 

850 primary's and 1300 sec. will be palenty of fuel.. the only thing I have heard bad about primary's it that thecar will have a bad idel.

 

It will idle fine. Its all in the tuning.

As far as injectors go...assuming 40 psi base fuel pressure 850's and 1300's would be reaching upper 80% duty at around 475 rwhp. That is why I'm going with 850's and 1600's. (According to Max Cooper's fuel calc.)

Who is using TEC3?

 

I agree about the injectors, the fuel calc. says that @ 80% duty and .64 BSFC the 850+1300 inj. are only good for 417 rwhp, while the 850+1600 are good for 475 on the money there's still a little leeway, because your BSFC is probably a little lower than .64 and the injectors don't max out until 85%. Even so, you still may want to get your secondaries bored to 1680 cc/min...

I haven't heard too much about the tec3, but I think there's some info about it at http://www.srmotorsports.com. If I'm correct, I think they use it on their race car....

What kind of custom FMIC setup are you using, do you know the flow/pressure drop characteristics??

Thanks

I thought 80% is where you want the inj duty??? 475 rwhp, Isnt that about all the t04s is capeble of, considering average tunning??? I really would like to know?? knowlegde me at this stuff.

 

Anything above 85-90% is really pushing it, and it becomes hard to control. So a little less won't hurt.

As far as the T04S other forum members have made really good power with it. Wargasm made 393 rwhp on 14.5 psi. This was on a day with 105' ambient temp. I believe he was seeing about 15 rwhp per psi of boost.(I could be wrong). So that equals out to around 500 rwhp at 20-22 psi. He was tuned very conservatively also. Cruser made 461 rwhp on a mustang dyno which is equal to over 500 on a dynojet. I believe his runs were at 20 psi. He was tuned pretty lean though. Not too sure about his exact setup. I think they both use the PFC.

I'm thinking 500 is definately attainable with TEC3 due to the much better resolution and accuracy.

 

The run where I hit the 461 hp more than likely would have been in a safer a/f range, but I was only running the stock map sensor so the PFC couldn't do its job up that high. We found out after that run the boost controller was acting a little crazy with the 14lb spring in the wastegate. On the same note the hp wouldn't have been as high either. I need to get that car back on the road and then back on the dyno.

Your setup sounds pretty good to me. Go with the TwinPower ignition, worked great for me. Definately go with the larger injectors. Sure your idle will be a little rough, but its not bad. I have had some problems with the engine flooding with the larger injectors though.

Good luck,

Ryan

 

Ryan,
Thanks for the advise. I'm gonna go with the TEC3 which has the ignition setup included, that way I won't need a twinpower or have to worry about more than 17 psi on the MAP sensor.

What was your setup? How much porting?

 

My setup was:

M2 medium intercooler
850/1600 injectors
sx fpr
Power FC
full open exhaust
Bosche fuel pump

I think I got everything in there. Doesn't sound like much when you sit and type it out, though.

As for my streetport, I had my done at Atkins rotary and really didn't specify anything specific. I just told them I wanted it ported. My tuner did mention that it seemed like it had a pretty aggressive port.

Good luck with your project. If I can help out in any way let me know.

Ryan

 

isnt the t04s similar to the t-66?? if it isnt the same?? t-66 is a t04s right??

 

No.
The T04S is smaller.
