if i may hijack this thread for a minute then i have a few questions...
i dont own an A4 but am seriously considering gettting one. i, like djintensive, am unsure about the 1.8 or 3.0 liter. now, i have done a small amount of lurking as well as "research" and have of course seen that almost all of the mods are for the 1.8. with that said i found only one for the 3.0, from T.A.P. i have no idea how good it is but purportedly will bring the horses to 238 for $500. dont know about tq. gains. now, i come from exclusively american V8's (easy guys) and as such have a natural aversion to 4 cylinders. but for $1000 one can get 215hp and 250lbs. tq from APR. which would bring the 1.8 to the level of the 3.0. but does it really? i suppose that is the question. it may seem foolish of me to ask as they might not be in business long if these suppliers didnt make good on their pony claims, but it seems a bit foreign to me to see, for instance, a kit from neuspeed get 216 wheel hp for $2500 which obviously outperforms the 3.0.
i am not looking to mod the hell out of this car, but i would NOT be happy with the stock 1.8 as it simply wont give me the power/torque i want. i also would be happier keeping a warranty and basically understand that the more i mod the less legs i have to stand on to get anything fixed- read moss? act.
so- if i were to mod a 1.8 turbo to, lets say, the neuspeed stuff to bring it past the 3.0 n/a motors output how long might i expect that motor to last? how much extra stress does that add? expect more breakdowns, etc.- sort of rhetorical but wanna ask.
and if i were to chip the 3.0 to add 20 more ponies is that detectable to the dealer? i've read that some arent but cannot remember who/where.
forgive the rambling and thanks for your time-- hell, i already used Gammba's great resource list of modders to get this info- thanks Gammba!
