Then make sure ur engine is well lubricated alll the time, and you keep up with the maintenance. My car has a rebuilt engine in it, clock reads 132k, engine should be around like 70k? and i have 0 problems cause either A) i fix it myself exactly as the how-to's, or B) take it to the guy who did the engine swap. If you still have engine problems, then i dont knoe wat to tell you...Heard enuff ppl sayin its not reliable. It IS very reliable, the 72, but u got to know how to take care of it...its like fucked up kids, do u blame the kid or the parent/s?

Holy hell, they're 3Ss NOT 3si's

P.S. Leaving the 6G74 n/a is retarded honestly. Where is the bang for the buck? For the money spent on sourcing the proper engine and then the 60k you could have a reliable fwd tt.

Though this paragraph borders on incoherent it is pretty accurate. Your cars don't make enough power to hurt themselves as it is...the talk of reliability needs to end. Our cars are old, if maintenance hasn't been kept up they will break often. If proper maintenance has been done the cars don't show their age, simple.

One 6GXX is not necessarily more reliable than another. I'd rather get a new shortblock or even a new engine before trying to swap to the 74 for no reason other than a slight hp gain and a rumor of reliability.

We counting *Ninja Coffee Edit* Diamante's too? They dyno about the same thing Von, boosted vs. N/A are night and day. Where is the bang for the buck? Where is the advantage (performance wise) that warrants the swap and it's expense?

Side note: How many non-turbo 74's have you driven? Do I have to have driven one to notice that they run about the same times in the 1/4 and put down about the same hp down on the dyno?

[xwire]

well seeing as were are talking of the swap in a 3000GT, I think a Diamante would be a useless comparison

bang for the buck, having a car that is pretty much stock (no added items under the hood, just a replacement engine) that has a LOT fatter power band, and is just as reliable as the stock setup... sounds pretty good to me

power numbers do NOT end at just peak, you need to keep in mind the complete power band, and a 3.5 has a little help down low with the extra displacement

I have installed a "couple" of 3.5's in 3S's turbo AND non-turbo, and it is a very worth while mod on both. this is not "hearsay" this is MY experience (not something I read on the Internet or on a message board) with them, there is no replacement for displacement, and increasing the displacement by a half a liter on a 3.0 is a HUGE increase

Thanks for chiming in Xwire. I would hate for my thread to become negative. I believe it is a good bang for the buck mod. That's why I'm doing it soon. My 72 has 89k on it and I would be needing to do a 60k on it soon according to the records I have from the previous owner, so why not swap it out and sell the 72 and get a 74.

As far as misinformation, AudiableSilence, in the thread, please show me where and if you know better please enlighten us. Also "reliable" and fwdtt don't really mix unless it is a full swap. I hear more about broken trannys and blown engines than good stories on 10:1 conversions. I made this thread to get info on how to beef up my ride w/o turbo for now because I use it for work on a daily bases. If I choose to go turbo later it will be a 6g74tt. I appreciate your input, but lets keep this thread on point.
