new vs. rebuilt turbos

How much difference is there between the two. I may need new ones and need some input. How long do rebuilt turbos typically last? I did some searching, but didn't find much on this. Thanks!

rebuilt turbos SUCK. i went thru two sets...turbo city the first time (leaked on the first day and eventually poured oil all over the place) and performance techniques the second time (sounded like a dentist drill and had to come off within three months).

they are a waste of your money...it is simply not worth it. just get a set of new and be happy for a long time...or upgrade.

m2 sells upgrades and so does BNR. if it was me..id go with one of those two. ... new jspec at the very least

typically rebuilds are under 1500 and new is about 3k.

but you will buy another set of rebuilds Im sure so you might as well go new or go with the upgrade. at least then it will be worth it.

I'm going to have to agree with what artguy has said. I'm going to get a set of turbos in a few months, Thinkin og either the BNR's or maybe the new J-specs....not quite sure though. Tell us how it all works out for you, and who you got them through.

Cheap alternative

Another alternative would be just to buy used ones. Jason from jt-imports.com sell them for 500-600 shipped I think. Not 100% sure but I think they are in good working condition and have around 40k kilometers on em. This would make a cheap alternative especially if you were going to eventually go single.

used turbos are not an alternative in my opinion....i saw half dozen sets from differerent big list members...all claiming they did not leak...sure enuff...oil deposits in the snails when they should have been clean.

go m2 and be happy. haha

M2s are rebuilds though, and so are BNRs, I think your comments are a little confusing in that respect Artguy. Oh, and we want dyno plots! When are you getting that thing tuned man?

I have to agree with artguy on this one. Rebuilt turbos are like walking into a casino and playing $1000 on your first hand of blackjack. You could get real lucky and have them work perfectly, or you could get stuck by the house and lose 1G. I've gone through 2 sets of rebuilds in 4 months and I've finally had it ... no more rebuilds, went with some '99 spec turbos.

If you're going to do the upgraded turbos, there's also one more choice ... www.turbo-power.com. Cliff is the guy you wanna talk to ... Checkpoint's upgraded turbos; well, those are his turbos. Give him a call; he's very easy to talk to about this.

hopefully i can dyno soon...thats all i have to say. Im running them non seq right now and need to do some work to put them back to seq. experimenting a bit.

regardless...the m2s are hybrids and i wouldnt consider them as simple rebuilds. the problem with the rebuilt stock turbos is their shaft bearing design and too small of compressor wheels/shaft. they overheat quickly...and cook those seals right up. the m2s run A LOT cooler and thus they are not prone to heat damage to the same degree. they also perform better. trust me on that

m2 is also a reputable vendor with quality products...unlike yer local turbo builder who is used to balancing and rebuilding truck turbos.

I beleive mine are starting to leak. 25k mi. on rebuilds from Mostly Mazdas and more (something like that). Anyhow, I am getting oil seeping out of the primary turbo intake filter. I was running 14lbs for a while but I don't think the stock setup likes more thant 12lbs.

I'm not sure what the longevity of the M2's will be but I can tell you they kick in quicky and would be more fun in the city than a single. Makes for a good sleeper engine.

for the guys that have had rebuilds fail on them; Were these rebuilt by a shop or did you rebuild them yourself?

Rebuilt by a well known turbo manufacturer ... Turbonetics. You'd figure that they'd understand the intracacies of turbos and their sensitivity to bearing clearance and the seating of the carbon seal. Add in the fact that most turbo rebuilders have a poor history with the Hitachi HT-12's ... most places will NOT offer a warranty on rebuilt HT-12's. Like most of us have already said, it's more expensive for new turbos but it'll save you time and your sanity in the end.

there are two shops that I have heard no complaints about their rebuilds...one is bnr...the other is a shop thru rotary reliability and racing (supposedly they come back completely cherry and out of a dozen or so sets they have done not one has come back in.

to put that last part in perspective...they had to sue turbo city (and won) because five our of six sets came back leaking within a week or two. RRR seems very happy with their new builder. 7148398018 ask for nick.

good luck...but regardless...i still wouldnt waste the money on rebuilds...go with new or an upgraded set.

Hey fellas.
I just want to inform you guys that I have found a solution to leaky turbos. I cant go in depth about it, but I am having some stuff custom made and have to machine a few things inside the turbos to get them to seal up well. I am also working on eliminating the carbon seals and ultimately every rebuild that I do will be actually better than new and will outspool and perform the stockers. You will be able to run a ton more boost reliably also . All the current customers that I have right now will be in on the new design. We will have to work out something...

take care,
Bryan

If the manifold gets too hot and is the weakest part of the turbo then why isn't there stainless steel manifolds? ...yes I know it would run about $1,000. At the very least, why can't the stock manifold be sent to jet-hot for 2000 degree coating?

M2's with a custom stainless steel manifold running 25-30lbs

lol. boost doesn't make volume! Just B/c you run 30 psi, doesn't mean you are going to make more power with another turbo at 15 psi

Jason. Just wanted to tell you that we carried the world record for most power with a single turbocharger, and it cam off a truck!!!! It made 1919 hp on a 348 ci ford modular engine.

2 sets in 4 months!? who ever rebuilt them must of done a sloppy job.. i got my turbos rebuilt about 5 months ago and they work perfect... not problems so far, if u are going to rebuild them its best to get them blueprinted

mine were blueprinted and balanced both times...the first set leaked from day one...the second soundled like a dentist drill and dripped all over my driveway....ditched those **** stock turbos and went with the m2 hybrid garrett setup.

you are one of the lucky ones...most of us are not as lucky.
