Does anyone have any expericance with the turbonetics stock turbo replacement? Will I also need to buy a new manifold, or any other parts?

Well first of all, there really is no stock manifold replacements. All the manifolds you see are for single turbo 7's. I have not heard of turbonetics stock turbo replacement... but if it is what they say it is, It can't be that bad... turbonetics is a great company.

Whether or not the replacement turbos are stock is my main concern. I am trying to find out if I will need to replace more than just the turbos themselves. I don't want to buy them just to find out that I will have to spend alot more money on other parts as well.

Has anyone heard of a turbonetics stock replacement? Will it work with the existing stock manifold?

Do you have a link?

As a rule of thumb, any stock turbo rebuild will leak and is not worth paying good money for. If you are looking to stay with twins, your best bet is to look into the 99 efini twins or go with the BNR new Stage 3s if you are looking to make single turbo power levels.

its an upgrade from the sounds of it, much akin to the BNR staged upgrades

RE Suzuki

why not bnr stage 2?

Unless something has recently changed, Bryan only offers one set of twins right now.....the 'new' 3s, with both rotating assys being complete replacements (he just reuses the comp housings and turbine housing).

Those wont be anything like the BNR upgrades. The BNR turbos come with brand new aftermarket CHRA's (bearing housing) which include a different turbine wheel, much larger shaft, and a much stronger thrust bearing. NO other upgrade twins come with any of that. All the others are basic stock rebuilds using your junk stock bearing housing and just the compressor wheel swaped out and the intake hole enlarged to fit a larger wheel. These turbos have all been rebuild so many times that the bearing housings are JUNK. This is why BNR stopped making upgrades like that and started changing everything to use a new CHRA, its VERY difficult to do and no one else does it.

RE Suzuki

no stage 2? thats too bad. Thought Stage 2 is some what affordable.

Goodfella, you seem pretty high on the BNRs. Did you ever run your car down the qtr. with them on? What kind of power did you finally get?

Getting to be about that time. I'm drippin' oil pretty regularly.

SPOautos

You'd just have to call Bryan and talk to him about it. He isnt actively "selling" them but he might build you a set if you cant afford stage 3's. Thats one of those things you'd have to call and check on. But he's probably going to tell you that those type of rebuilds are ticking time bombs because they are. The problem is that there arent any high quality replacement parts on the market. Thats why the rebuilds seem to be hit or miss. He doesnt like to build them but give him a call and he might build you a set if you really need some turbos and cant afford the good ones.

BTW - I think the stage 3's are very affordable. There isnt anything else you can get cheaper except for junk.

RE Suzuki

I thought stage 1 was "regular rebuilt". Would I be safe to run stage 3 with M2 Stage 3 ecu, dp, bonez cat, greddy smic, arc induction intake?

because from what i've read/heard lately, that's the impression i had gotten. i know there's not alot of info included in that satement, i was just trying to pass on the little that i had.

No drag racing yet. Here in NJ the weather is going to prevent that for the next couple of months. Based on what spo has accomplished with the old BNRs and based on my driving impressions of these, I expect some real nice trap speeds, in the 125ish range. On pump gas that seems to be about the limit for any FD. I am waiting on JD to tune me, at which time I will have some high boost dyno #s. I plan on using race gas and seeing just how high they turbos can be pushed.

if you just want a basic rebuild you can get the kits from turbocity for 150$ a turbo. don't know anyone who's done this though.

Sorry, there is no link. An aftermarket performance shop is offering to sell the Turbonetics turbos, but doesn't feel confidant in performing the installation. I don't want to buy a set of turbos, then show up somewhere else and have them tell me that I just wasted a bunch of money. Basically, I want to be very clear on what I am buying before making the purchase.

I am told that they are factory-rebuilt turbos by Turbonetics, that they are neither an upgrade nor a downgrade - they will essentially be the same as the stock turbos. There is no part/model number, and it should be able to be installed without any other modifications. I have been looking for this type of replacement (inexpensive and simple), but reading the replies posted on this thread I am starting to have second thoughts.

I would like to keep the car stock; I do not want to modify the whole car just to replace the turbos. Is this possible? Are these Turbonetics rebuilds legitimate?

bigmack000

dude! i showed you pics of what the turbonetics twins look like! now think about it why would a after market company make a OEM performance part. THEY wont so they make upgraded parts. thats what the turbos your talking about are. if you want them you will have 2 fidn someone with a used set and buy them and get them rebuilt or not.

Anyone know anything about turbo international? They manufacture rebuild kits. Are they the supplier of the turbo city kits? My turbos are tired but there has to be a middle ground for oem. Or maybe not.

tdill70

joel, I agree with you about the turbonetics turbos - it does not make much sense for them to build stock turbos - but that is what the sales guy is telling me. He is saying that they are rebuilt factory turbos, that are the same as stock.

If they are rebuilt factory turbos, does this automatically mean that they are upgrades? (Do the turbos get 'upgraded' as part of the rebuilding process?)

Also, if these turbos are the same as the ones in the picture (meaning that they are upgrades over the stock turbos) what other changes/upgrades will be needed?

If all you want is a stock car that's reliable, then 99 spec turbos are the way to go. Call rx7.com and check their price, I believe they have them for around $2500. These are new turbos that will last as long as the originals and won't require a bunch of supporting mods.

I would also advise that you go with the 99 spec turbos. You cant beat brand new and they are also more efficient.So for one thing youll know theyre good.Cause theyre new and you also get a small boost in power as well.

I'll third that. Ari and Chris are Big Pimpin' Rotary Studs and will gladly talk to you about the efini twins---972 530 3335, tell em Rich sent you.

Just for further clarification: stock rebuild are JUNK and WILL LEAK the majority of the time, esp some 150 dollar 'rebuild' kit. Stock turbo R&R sucks enough that it boggles my mind as to why people try and take a shortcut when it comes to this.

All rebuilds, upgrades, ect ect no matter where you get them use the same replacements parts inside the turbo. Hitachi does NOT rebuild these turbos so when you pull them apart to repace worn internals you have to buy a "rebuild kit" and there is only ONE company that makes the rebuild kit. There might be a bunch of companies that sell it but they are all selling the same kit....and its junk. The parts inside the rebuild kit dont spec right and this is why they die in less than a year and often smoke from the start. In addition there are no replacement bearing housings so no matter where you go you are going to get your old bearing housing back or another used one that is in better shape if yours is unusable. Then they charge you extra for using thier better condition bearing housing.

THIS is why BNR stopped rebuilding our turbos about a year ago and spent 6 months perfecting this new design. What he's selling is a brand new turbo (bearing housing and all) that he basically adapts the stock compressor housing and turbine housing to so it will bolt up in the car.

The 99 twins are nothing more than a new set of twins just like your old ones. They have the same weak thrust bearings, same weak shaft, same small compressor wheel, ect ect ect. If you pull the turbos apart there are no internal differences between the standard 99 twins and our 93-95 twins. Even the RZ twins use the same crap bearing housings, small weak wheel, ect ect. They are nothing more than our twins with a slightly SMALLER compressor wheel and the coating on the inside of the compressor housing.

I cant for the life of me figure out why anyone would pay more money for any type of stock turbo over the BNR's. It just doesnt make any sense to me. The only thing I can see is if they are already borderline with thier a/f ratio and are worried that its going to go lean.
