I have a 1997 SE with practically nothing done to it. Right now I have a 130k miles on it and by the time I get the money for a turbo kit I'll have about 135k miles or more. I've had no major problems so far and it is running great. Should I rebuild the engine first or should I just sell it and boost a newer max w/ lower miles on it? Thanks for the input!

I would just do a motor swap. You can get vq's with low mileage for like $750.

I think all comes down to how the car was treated but that is getting pretty much up there. Might as well blow up one engine and swap a new one in.

Thanks for the info, I like the idea of a motor swap instead of getting a new car or rebuilding!

So what are we looking at? I checked that web-site and it asks for either "Engine" or "Engine Block" Engine Block is way cheaper, so I'm guessing I would need a whole engine? I've been saving up alot money this past summer. I have enough for the PFI kit, but now i'll have to save up some more for a new engine

you need the whole engine, you could run the pfi kit at stock boost 5 to 6psi and be fine with your current engine for along time its justt when you start to turn up the boost youll run into problems

Please, don't post things like this. It makes it sound like you have no clue as to what you are talking about. The term "Stock Boost" doesn't even belong in the sentence with VQ30DE...it was never boosted in stock factory form. There are still TONS of things that could go wrong with "just" 5-6 PSi, including melted and broken pistons/rings, connecting rods, seals and gaskets, tranny/clutch...

Boosting an engine that was never meant for boost is always a challenge (mainly due to the overall engine compression ratio, but also due to inadequate parts strength).

you know what i mean when i said stock boost

and i dont think ive read any post obout people melting pistons or breaking rods at 5 - 6 psi every bodys been at like 9 or 10 when they went or the mevi bolts come into to play

i was at 6 psi when i blew my engine!!

People think that just running 5-6 PSi is safe for our engines...

I honestly don't know what people are thinking sometimes. That's why people like this subs1000w worry me...

crowghost

Well to be safe, I guess I should get a new engine and hope nothing happens to that

subs1000w

alright i will admit i do think its safe from what ive read but i guess HAL's car would be a good example since he has yet to blow his current engine which is pretty amazing. i figure if his VQ can take 10 or what ever PSI he desides to run from day to day and only HAL and god no what shot of nitrous, a properly tune VQ could take 6psi dayly

now are you saying that its dangerous to run 6psi because its high milage

or its dangorous no matter what milage because i would think if his 135k motor has good compression it would be no different than if his motor had 35k on it

and i will assure you i will rethink all my futer posts in the boosted section because i dont want to be responsible for someone blowing up there engine

I'm saying that running 6 PSi on an engine that is not built for any type of forced induction is dangerous...

BUT, that danger is something that we can live with in order to extract the performance we are seeking...

Higher mileage = more wear and tear on things like seals, piston rings, and bearings. 135K on an engine is not an ideal time to turbo it, unless you just want the practice of swapping engines. If that's what you're after, then by all means, throw a turbo setup on your engine. You'll probably get practice in a clutch/tranny swap as well...

thankyou i understand now

Didn't you have the oil return line going into the crankcase?



6psi should be fine on our motors. If your car was taken care off you should be fine, turbocharging it will decrease the life of the motor, but as long as you do regular mantience and safeguards for what your are doing you shoudl be fien for quite awhile.

If the engine checks out in terms of compression and leakdown tests, it should be "okay" on low boost. But I'd be eyeballin' another used motor as a back up at some point
