Man I am selling a 87 t2 for 2300 bucks. Its better off that you buy a t2 and sell the NA to some other kid and let him do a swap. Then you can ship your spare t2 motor out to Kevin Landers and have him rebuild it and port it. Then you will be on your way to making a reliable 300 rwhp. Other than that you are just going to grenade a tired motor jerry rigged into a NA and blow a apex seal the first time you boost through 4th gear. End of story

the only reason turbo engines generally do not last as long as n/a engines is because of one thing, your foot.

Another net wrench kid trying to prove superiority when he likely spends more time in the bathroom than in the garage.

I am posting from Experience, that a car boosting 12 psi on a stock turbo and motor will not surpas 85% pulsewidth on the stock injectors. My car is running this way. This setup will not produce 300 at the wheels so i dont know why you would bring the 300hp number into it.

I was simply commenting that those switching injectors just to run 3" exhaust and cone intake on a stock turbine, stock port motor are wasting money and running rich and losing power. (assuming a FCD) The stock injectors can push 250 min at the flywheel which is all your gonna get with exhaust and intake on an otherwise stock car. If you have no way to tune the car there is definetly no reason to switch injectors, but why put injectors in there that are not needed when the stock ones will run in safe pulse widths on the setup you originally posted that i commented on.

HAVE A NICE DAY!

everyone here makes great points, but what it comes down to is what you want. i drive an n/a and yes i have driven several TII's, and for now i like my n/a. i choose to shoot for the 220 hp mark with that because it's easier for ME to work on, and it's what I want now. a 300+hp t2 is in my future though. basicly do what you want. although everyone may not agree with what you want, it's a great group we have here so you'll have the support you need to attain your goal.

Stock NA motors have higher compression... It wouldnt be a smart idea to add a turbo would it ?

You have no clue what you are talking about. But, dream what you will. The ECU is tuned for this setup, the injectors are near max duty but still in stable consistant operating range. Wideband shows low 11s in all gears under WOT up to redline. If i have to rebuild it is not going to be because of a lean condition. Did i mention 255lph fuel pump rewired? Car has that too....

I feel like I feel like Napoleon Dynamite IDIOT

I suppose your making 300whp on stock turbo to huu.
I suppose your making 300 on four 550cc as you say all at 11 AFR too huu?

I would officially not work on my car now with your advice if I had harpies on my *** hole.

Stock turbo is not good for 300 either is four 550cc injectors
Stock fuel is not good for 12psi on stock turbo either. Why don’t you try taking a pole on how many motors have popped on here from that combination.

Please stop pulling **** out of your ***.

Look dood I am only trying to make a simple point. If he maxes out his turbo like that the stock fuel system will not cut it, to meany people have shown this and I understand your duty cycle on paper is right and so on and theori it should work. I understand you can over flow your system with your walboro and so on. But if this is the case this needs to be exsplained to the poster so hes not pulling his hair out trying to figure out what needs to be done to his car.

My point is maxing it out stock he needs to take attention and least complicated way is to add some 720cc injectors and be on the safe side. Just b/c you can over run it with a 250lph pump on perfect 550cc makes the cut without falling into the danger zone dosent mean its the easiest rought for him.

I am not making anywhere near 300 hp even at the flywheel. I never claimed to be. Maybe 270 on a good day at the flywheel.

Why keep going back to the 300 hp number when i was simply responding to your statment....

Those "simple" mods will neither provide a safe or tuned machine much less one that will produce 300hp.

But, 12psi on the stock turbo is not too much for the stock injectors provided they have been cleaned. And i wouldnt run higher than stock levels of boost with ANY injectors on the original fuel pump with original wiring. The fuel pump and rewire should come before any kind of other mods on these cars.

14psi will pop the motor on stock injectors i understand that. 12psi will not.

Ever hear of an adjustable fuel pressure regulator?
Increase fuel pressure, increase fuel delivery for the same duty cycle.
4 x 550's and bringing fuel pressure up 10 psi will support.

Period.

Before you make such concrete and condescending statements, make sure you are correct.

Besides the fuel pump, stock T2 fuel system will support 12 psi @ 40 psi fuel pressure from the stock turbo while maintaing 11.5:1 AFR's throughout the entire RPM range.
Been there, done that.

Completely false.
A forced induction engine will be able to make identical torque at a lower rpm compared to N/A engine making the same torque.
Engine stress and wear increases exponentially with rpm. So if you need higher rpms to make the same power, the engine will see more stress and more wear.

You sure jump down people's throats for someone who really has no clue what they're talking about.

Turbos needs more fuel to run safer.

So all else being equal, the turbo motor will run cooler due to the lower EGT's.
This implies reliability will be in the turbo motor's favor, ignoring all other factors.

Seriously though folks, all the NA guys out there hatin' on the turbos, how many of you been in one?
Very few people would take the NA over a turbo once they have a ride in both.

I used to own a TII. I do miss its power however.
