Default To FI or not to FI?

I'm thinking about going turbo in the near future. The thing is my car will probably have 60k+ on the odometer by then. If I run low boost is it safe to turbo still? I'm thinking maybe around 7 psi or lower if necessary. But not too low that its to the point where FI would be pointless. Obviously the car is my daily driver. I dont track it. I might run it once or twice at the track just to see what it can do. But other than that I usually just cruise with some spirited driving every once in a while. If you guys suggest that I build up the motor first then I might just stay away from FI in general. So I'm all ears on your opinions guys.

I don’t see a problem, especially with low boost, and a good tune. If you are looking for decent gains and not huge numbers, have you thought about a supercharger? Supercharger with the lower torque numbers seems to be easier on the engine. Either way you should be good.

Yeah I was thinking about it. But the thing is, I figured that the turbos wouldnt be putting as much stress on the engine because they have to spool up. Unless someone can chime in on this and tell me otherwise. I guess the added bonus is you get a nice blow off too. Lol.

My understanding is that the high torque is what contributes to the engine failing, which is something the supercharger cannot produce like the turbos. The supercharger is a more linear power, while the turbo is more of a spike. I took a ride in a JWT TT G35, and there was virtually no turbo lag, spool or no spool the torque will be present. Like I said earlier, either way you should be good if you dont go crazy on the boost.

Yeah sounds good. I think 350hp would be good enough for me. I'm also just wondering how all these guys afford to get these kits and whatnot. I'm saving for it but I also got stuff to pay for since I'm still in college. But I see some students have gone FI too. Someone let me in on their secret. lol.

Sounds like you have nearly infinite research left to do if you really plan on going F/I. You don't just slap turbos on, force it to run lower boost than normal, give it a "conservative tune" and call it safe. Hell if you really wanted to do that, it's certainly not worth your time or money to do so. Any F/I kit can blow your motor in it's stock form, even on a so-called conservative tune.

Some motors will not blow on a stock turbo kit. Some will. Are you prepared to face the consequences? If so then start by searching the forced induction forum.

Read every thread you can get your hands on, that contains useful information.

There is no "secret"...it takes a lot of money, and you should be prepared to blow a motor. College student with a Z as a daily driver? Not ready for taking this car F/I if you ask me. Sounds like this will be an expensive project for you, which is not good because you should always have plenty of money left over for incidentals.

The only way I can forsee a college student paying for this with their own money is by getting a lot of help from mom & dad (i.e. tuition fees books rent food clothes insurance), and possibly living at home to avoid paying any rent.

If you can afford $10,000+ to rebuild then by all means do it. If not, dont count on anything being "Safe" Even the best set-up FI cars blow, while others have no issues.

the chance of you blowing your motor on safe boost is there. but don't let that scare you away from going FI. I'm currently in the process, I get my car back next week. There's chances in everything and this is one that I'm willing to take....think about it...

Yeah man. I'm just a little unsure. I'm trying to think if I can save up for it or not. I think I can, but if my motor goes then...

How much is it for some rods and pistons kits? I know theyre are different brands and what not, but I guess I'm speaking in generalities.

Most important thing is to get the install and the tune done right. That will buy you enough time to safe up for that dark day if it ever comes.
Don't try and cut corners and get cheap, do your research

Not true in my case and others cases, and my car didnt put down crazy power numbers. I think its bad advise telling somebody if they install/tune properly it will buy them time...

Dont even waste your time here...just ask MRC or another shop thats qualified. They'll definately let you know your options, and get direct pricing from them. There are plenty of shops in our area that would rather help a customer. But my personal opinion... you gotta pay to play. If you have 6 or 7 grand to dump AFTER your installed kit, then your safe. Thats about how much it'll cost to get a new built engine installed (about). But i figured, if youre going to do it, do it right the first time.
Im being mad straightforward well..because money talks, BS walks lol. If your still deciding, you're not ready.

try again....double that price there is more to it than buying some internals
Im at around 25k for my build engine after everything else that needs to go with it

Wow. I asked a few shops once and they said they can have it said and done w/ a TT and built motor for 17-18k. I figure if you do it seperately it'll cost more. 25g's isn't quite worth it to me. But then again..im broke haha.

edit: forgot about fuel system, clutch, brakes and wheels ect. That will easily get one to 25-30k for FI.

Sleeves also adds more to the price of machining/parts....which is what Im pretty sure MTC is doing.

Are you guys referring to some crazy forged engine? What I had in mind was just getting the new rods,pistons,and studs. Then getting the block rehoned and whatnot. Reason I say that is because I wont be boosting that much. That and I dont drive the car hard much either. What do you guys think?
