Running at low boost, how long would the stock engine hold up?

Multiple dependencies here. Mileage? How proactive were you/previous owner on maintenance? Auto or manual? What do you mean by "low boost", 4-5 psi?

Honestly, as long as the install and tuning are done correctly, you're a stickler on your maintenance, and don't beat the **** out of the car, it could last as long as any other motor. Boost does stress the internals more, but it's anyone's guess really as to how long it lasts. I hope mine lasts until I fubar the chassis beyond repair.

I only have 70,000 km which is about 43,500 miles. Ya most boost I'd do is 6 psi, I'm not looking for tons of power just some more fun. I use synthetic oil and do my oil change every 4000 km or 2500 miles. But I stick with my maintance ahead of schedule.

6 PSI is not even worth doing for the amount you pay to turbocharge

i dropped 3500 for my tsi kit and i must say, im fricken happy with my 3 psi untuned haha

i know on my 06 R-Series can handle alot more then it puts out,
Even the K-series can handle i think like 30PSI before the bottom end blows on ya.

Irrelevant comparison.

There's also a big difference between what it CAN do, and what it will do for thousands of miles. The bottom end ought to hold up for 12 or 15 psi, you wont get it to last too long. on 7psi, plenty of people have made em last. its all in the tune, you're gonna end up needing a new head gasket and ARP studs, thats the first failure point.

i think i know that, i stated the MAX PSI, doesnt mean youd actually go there? dang! that would be insane but its just to give a ballpark figure, and as for comparison....not really to far off. Honda engines can do more then what Honda puts out, these cars are well known for the torqueless engines they are unless you do something about it.

I wouldnt suggest running even at 20PSI at that, but it sure can way more then what it has.


.03 (inflation) lmao!

I beg to differ. 6 psi is knocking my socks off right now. Without some more serious suspension work, it's hard to put 6 psi to the ground sometimes.

now thats what im talkin about right there, 6-8PSI is pretty crazy but at 10PSI would be sick! forget over 15 which would kill you im guessin'

if my civic had even 6PSI i would be smiling all the way down the 1/4mi.

How about 10 PSI ?

How long would it last at 10psi? Not very long without an uprated gut.

i was boosted at 10psi for a year with no probs then i got greedy turned it to 12 and had a boost spike to about 14 which lead to the head gasket slowly start leaking...but back down to about 9.5 with no problems and im running an fmu which you can't tune so id have to say it all depends

why dotn we just go up to 22PSI? HAHA

How reliable is your mechanic???

at 6psi u should be around 185-190 ..

As speedfoos said (and I think from reading his Turbo install thread he knows his **** XD), just be nice to your car

If you weren't going to do any block work (low comp pistions, rods and the like) , theoretically the A1 should be more reliable than the A2 because it has a lower compression ratio, thus, in short, less chance of **** screwing up
