N/A-T question.

[Sl1dewaysSupra]

Ok, before I get flamed I did read the N/A-T sticky. My question is on the one thing I havent seen covered really. What is the most reliable way to run coolant to and from the turbo? If any N/A-T can explain what they did it would be greatly apreciated. (I am strictly going to turbo the na motor, not swap in the GTE. More of a 1/2 na-t than anything.) Thanks much.

My dad who has almost about 8 years experience with 7m's told me on a NA-T if you're using a stock CT26, the coolant line isn't needed.

But he told me this: Look at the lower rad hose where it clamps to the block, notice a banjo fitting with a rubber hose that goes up to another banjo fitting on the thermostat housing. Coolant runs thru there and you can tap into that for the turbo.

I will be doing this on my NA->T project when I finally get all the parts together.

Hope this helps.



PS: please get a Cometic headgasket and ARP fasteners before you boost it. It will save you from headaches in the future aslong as you keep it under 10psi. (10psi is pushing it on a high mileage 7mGE)

 

[Sl1dewaysSupra]

Yeah, motors getting fully rebuilt. My CT26 wont be stock(57 trim). So I should be able to run one line to the lower banjo and one to the upper?

 

[DegreE]

Correct.

57 trim on a 1/2 NA-T? Risky business!

 

[Buddafucco]

The stock ct was designed to have coolant running through it. You are asking for trouble if you take that advice. You can tap the coolant lines by the waterpump (like degree said) and the waterneck.

Maftpro and a fresh motor should help. My 12-14psi goal on the other hand...
I dont want to risk coking the bearings on a fresh 57 trim. Or any turbo for that matter. I figured that if Toyota put the lines there I should do my best to keep it that way.

 

[Sl1dewaysSupra]

Ma70.Ent, do you think the 46 trim is a little safer?

 

[Ma70.Ent]

It'd be safer just to go GTE electronics. The 57 trim at stock boost flows more than a 46 trim, so in reality, even if you run stock boost on a 57 trim its like running elevated boost on a 46 trim, and from what I've heard, running stock boost is what you should do if you're doing GE electronics. That's just my take on it. I could be wrong or whatever, but I don't really see any "running" GE Electronics NA-Ts. Jong abandoned his car a long time ago cause it was too costly in the end IIRC.

 

[DegreE]

You're using GE electronics? wtf? No man, go with GTE electronics. Its not hard to find all the stuff.

So far I'm only missing only the AICV and the IC piping. And I've only been looking for 2 weeks.



Edit: I still need to buy my headgasket and studs.

 

[Sl1dewaysSupra]

Im using the MAFT Pro. I can tune everything w/ it.

^ do what you like but i ran on ge electronics for a total of 2 full days (about 250 miles). i swaped to gte stuff the 3rd day after the swap.

as far as the 57 trim 12-14 psi will be to much for the pump. the max on a n/a-t with the stock ct is 11 psi IMO.
tho my setup is not the average na-t, i am running a 60 trim ct on a 10:1 n/a-t with meth, fmic,3" back , maft pro and a tt FP with AFPR. my goal is 400 rwhp with minimal lag and DD'able

but the 57 isnt to big, just make sure not to put over 8psi to it till you know what the a/f is and where your timming is.

That is a similar setup to what im going to use. I figure I can always swap the GTE electrical like you did if I don't like it for whatever reason. I just decided to do it this way for the chalange and the chance to make the car my own, not just another NA-T or GTE swap. The GTE swap or even the NA_T w/ GTE elec. would probably be cheaper, safer and easier but I want to see if I can manifest my imagination into something tangable.

Not flaming you or anything, what ever you want to do with your car is cool.

But there's a reason why everybody switched to GTE electronics on their GE when going NA->T....

1) You can't use a SAFC on a GE AFM

2) Coilpacks > Dizzy

3) Injectors don't put out enough for the high demand of boost.


Those are the main ones I can think of right now off the top of my head. Simply enough, GE electronics arn't made for boost.

...I just decided to do it this way for the chalange and the chance to make the car my own, not just another NA-T or GTE swap...

Thank you, lol.

I have a NA-T in the works as well, I'm trying to stay away from GTE electronics for as long as I can. I have everything ready besides BOV and fuel computer. Good luck on your projects.

 

[DegreE]

So far I have:

Valve Covers
3000 Pipe
Intake Manifold
Throttle Body
Coil Packs
CPS
TBPS
CSI
BOV
ECU
Apexi SAFC
Harness
Turbo
Turbo Manifold
Oil Pan
GTE Fan
Intercooler
Injectors
Fuel Rail

I'm still waiting for ARP headstuds, Cometic Headgasket, ICV, Down pipe, Oil lines, Intercooler piping, intake, AFM and random gaskets and seals, GTE instrument cluster.

The MAFT Pro will allow me to run speed density, no AFM is needed. I have Turbo injectors. Like I said, its going to be a hybrid.

You can't use a SAFC on a GE AFM

You really can't? My brother got his hooked up to his car and he has a wiring diagram somewhere and it seemed to be working, and I'll be doing it shortly. When I say it "seemed to be working", I'm referring to the fact that the SAFC monitored stuff on the screen, although I'm not sure if it can be used to tune it. I think that jong (the originator of the 1/2 NA-T, or GE electronics NA-T) used an SAFC to tune his car. Are you referring to the fact you can't tune the car using the SAFC, or you just think you can't? In other words, are you actually sure of your statement or are you just going by rumor?

You can hook it up, but the GE AFM signal is reverse from a GTE AFM. My dad can explain it better than I can. Basically, if he changed any settings in the SAFC, he is prob doing the engine more harm than good.

So you can still monitor the TPS and RPMs and stuff... but as far as tuning, your brother really just has it for looks.

My brother _had_ it. He gave it to me because he changed his setup, plus, hes turbo now

Anyways, let's see if anyone else has some input on this. I want to know if I can use the SAFC I got for free or not
