I have been looking into buying a single turbo upgrade, preferably the T-78, The kit comes complete with top quality parts, stainless manifold, turbo,wastegate, air filter, it also includes all necessary hardware and instructions. I understand the stock fuel system is able of getting some where near 525hp. This kit says "400+ RWHP at 15psi on pump gas and with proper tuning ".

What else do you all reccomend I purchase so my engine gets the most HP is can get.

Obviously I'll purchase a dp, I already have exhaust (hks super dragger) its pretty much stock, but i have put new vaccum lines just to be safe.

please comment back with ideas or sugestions on which items i should buy, fuel system, electronics,ecu upgrade, ect ect..

thanks - jim

 

bigger fuel pump, prolly nippondenso, PFC with commander, hi flow cat or midpipe, a t78 map for the PFC some type of aftermarket intercooler. bigger secondary injectors umm... and prolly a few other things.

 

The Greddy T78 kit does NOT come with an air filter, the wastegate isn't plumbed into the downpipe, it comes with it's own downpipe that does NOT fit U.S. model FD's.

The stock fuel system can support ~350RWHP. You're going to need bigger injectors, an upgraded pump, & an ECU. Then you will need a boost controller, an air filter, a blow off valve, a J-spec LIM, & an intercooler at the very least.

 

The T-78 kit does come with a filter and the DP will work on US spec cars with a little modification.

it comes with a crappy greddy air inx filter and the dp fits you just have to shave the LIM a little

 

Basically I have this on my purchase list

1. Boost controller (Greddy profec B)
2. Haltech ECU (going to have someone else tune)
3. Entirely new fuel system (bigger injectors 850cc+)
4. Greddy 3-row IC (good for 525+HP)
5. After Market DP (3 inch)
6. Upgraded radiator (fluidine)
7. BOV (hks)
------------------------------------------------------------------------

Later I want to work into getting an upgraded throttle body, something bigger not sure what size but nice and big and something that will let my engine breathe.

please provide me with the item i miss or you reccomend.

 

The T78 kit comes with a 3" downpipe. which doesn't fit the stock U.S. LIM unless you modify it. But it does fit.

 

Remember that with the Haltech you're going to have to start premixing your fuel. A PITA if it's a street car. PFC lets you keep the stock oil metering pump.

 

So in other words it would be less time consuming if i just bought the pfc, and if i buy the pfc i wont need to buy the tuning controller if someone else is going to tune it right?

 

You putting this on a stock engine?

Mistake.

Why you going to spend that much money on the turbo and supporting hardware on something that flows that much CFM on the stock engine?

Do it right, and do the engine up with a port and a rebuild. I prefer Pineapple. Look at how many people with stock (ported) engines strap a T-78 on it and blow it (no offense to anyone).

 

i have seen lots of ported engines blow. that is not a very good assumption to make

 

well its a bran new engine we originally wanted to do an over haul and port it, ect.

its only got 16k miles on it so i do not see why it would not be able to handle what i'd want to do with it.

 

Yea, well for one, a monkey (like myself) could install the PFC, just 4 wires to cut from the harness. As you said, if you're not the fiddling type, you don't need the Commander if someone else is tuning it for you.

 

Why is putting a single turbo on a stock motor any worse than putting it on a ported motor?
Sure, you're not going to get as much power as a ported, but it should be reliable if you tune to a power level within reason. I mean, I was under the impression that porting actually makes a motor a little less reliable....ie the lesser warranties commonly given with ported motors. Is that true?
If a reasonable power level is maintained, it seems to me that having a single turbo is all positive. You get rid of tons of heat, you simplify the operation of the car, and you gain power. The only negative would be emissions I guess.
People blow motors all the time on a variety of diffirent setups. Anything can, and will happen on these cars.
My buddy had a nicely built motor, and it let loose under normal acceleration out of a toll booth. There are tons of stories just like that.
**** happens.
Risnd34th, if you're looking to make the most power that you can, Badog is right. Do it the right way. Port it, otherwise you just simply won't have enough flow capability.

 

I think YOU have caused alot of ported engines to blow. Okay, other people may have been the cause.

But where is the sense on straping a high CFM turbo like the T-78 to a stock engine? Rebuild it to better than new, port it, and bring it up to a level to support the air flow. Dollar to performance value, there is the smart money?

 

and that try to run the car untuned for that level?
Does that help?

Strapping a turbo like the T-78 to a stock block and running at 20psi is not going to last as long a block setup to handle that level air flow and boost. Even if both are tuned in. Why set yourself up for potential failure, sooner? Build the sucker up!

 

apparently a stock FD port can flow enough for 400rwhp with stock turbos.... it may not make as much as a ported engine but if my engine was fine i would have left it alone till it broke then got it ported yadda yadda

 

Its like this the kit (by itself not other modifications) produces 450-500 HP, now I understand it would not benefit me to just put on the kit and tune my ecu that i can hopefully purchase soon (haltech) because chances are yes, it would blow.

I will port my engine no doubt before I do any major work to it, im just saying people make it seem like if you put a T-78 on it its automatically going to blow, and i figure well maybe THERES blew because it wasnt properly tuned, to were engine didnt get enough of something air flow, fuel ect..

 

There is no reason putting a T-78 on a stock motor(non-ported) would make it blow. The only issue is that you can only make so much power with the stock port.
You would have to tune for it, and of course mod the periphery of the motor(fuel system, ECU, Etc.) to prepare for the diffirent power curve and level of power, but the stock port itself should not be an issue for anything with the exception of power potential.
I'll let you know how I do when I put the GT35/40. on my motor(stock port). It won't be for a while, but i'm absolutely planning on it. I'm just building up funds. That is all I wait for.
People blow motors on the twin set up as well.
If you stay within the limits of the stock motor's flow potential, the single turbo is not any higher risk than the twins. As I said before, if anything, you're better off.

 

Yeah I know i didnt even know the bore size on the stock port, I have a guy who ports engines turbos, ect he did my friends intake and it helped alot...

I'll have to get him to port mine.

 

port scmort, talk to ErnieT

 

I wonder how much it would cost to port it, since its a rotary engine what exactly do they port the throttle body or what?
