EBAY turbos, anyone???
 
I have a 13b-re I'm about to bolt in...how are those $300.00 ebay turbos (xs Power) and how do you select one...I hae the twins on it now and want to take them off...I also want to know if I can use a stock S4 or S5 turbo on it will that give me more performance than the twins in seq mod controled by the haltech??? also will the stock S4 and S5 turbo manifods work on the 13b-re with the stock S4 or S5 down pipe.... I have a 91 vert

Don't do it, well, unless you like throwing $300 in the wind. The stock turbo/downpipe will bolt up fine. Get a used good turbo before a new china turbo.

I'd keep the twin un less you aim for big power in which case a 300$ turbo won't cut it. The saying always goes, you get what you pay for.

The ports on the RE are radically different so I don't think the stock TII manifold could just bolt-up.

whereiscarmensandiego 06-04-08 04:51 PM

so u bought an expensive motor and now u want to skimp on the supporting componets????

it dosent work that way

1991rx7vert 06-04-08 04:51 PM

you mean a used S4 or S5 turbo?? will it perform better and more reliable than the stock twins???

1991rx7vert 06-04-08 04:54 PM

the intercooler, motor, lines, clutch, BOV, engine hoist, and misc, has used most of the budget only have about 1600 left and I need 800 for the tunning!!!! $800 left.. oh yeah and gas too

coxxoc 06-04-08 04:57 PM

S4 or S5 exhaust manifold or turbo is just fine. The 13BRE exhaust ports line up the same. If you were referring to intake manifolds, that is a big step backward.

The stock twins on the 13bre are small. You can probably make the same power with a single 2nd gen turbo and save yourself the extra downpipe fabrication work.

Again, if you are going to do the work for the swap, you might as well get a better turbo though.

1991rx7vert 06-04-08 05:05 PM

yeah i guess I'll try to go on ebay to find a stock turbo and downpipe...it was going to cost me 300 bucks for the downpipe...and no I wasnt talking about the intake...

whereiscarmensandiego 06-04-08 05:11 PM

i just threw a nice turbo setup for myself together on ebay for close to 500

i used a good but used turbo and i bought a mani and wastegate they are cheap ebay parts but they will work atleast the turbo isint cheapie

and as far as 300 for a dp goes that way to much u could buy the flanges and have u one welded up for about 100 or so

1991rx7vert 06-04-08 05:15 PM

how do you know what turbo to get??? GT45, to4e I don't know the diffrence!!!!

joeylyrech 06-04-08 05:35 PM

any turbo exhaust manifold will bolt on the the RE,and yes you ca run a stock S4 or S5 turbo,mani and downpipe

arghx 06-05-08 07:52 AM

If you had an REW I would say go non-sequential (versus ebay turbos), but the RE turbos are smaller and probably aren't worth keeping. Just put in an s5 turbo and manifold for now.

If you do have the money to gupgrade, best bet is to buy a turbo kit (new or used, look in the 3rd gen forum) designed for an FD and make some modifications from there. FD's have way more aftermarket turbo kits than FC's.

1991rx7vert 06-05-08 12:04 PM

is $250 agood price for a used S5 exhaust manifold and used S stock turbo????

$200 is a better price. depends on the mileage of the turbo i guess.

Just to satisfy my own curiousity, how many of those bashing the China turbos actually have any direct, first hand experience with them?

You need to stop right now and answer these two questions:

1. What is your budget limit? Be honest.

2. How much power do you want to make?

1991rx7vert 06-05-08 12:18 PM

around 300hp is good for me i think i'm just going to go with the s5 stockmanifold and turbo to replace the stock 13b-re turbos for now so I can clean up the engine by removing everything...I already rremove power steering pump and converted the rack...i figure it would be easy to remove all the excess if i replace the twins since I can't tell what the twins need to operate (vacuum lines etc.)...how much hp will it get with the stock s5 turbo setup??

I don't have first hand experience, but do have a working relationship of one of the guys who got their production started.

I know the guy who got them hooked up with the Chinese supplier for them and started getting them produced. In fact he invested a lot of money in the Chinese supplier thinking it would be a good deal. Hey, who wouldn't want a $300 quality turbo? He promptly dropped any business with the Chinese supplier due to bad quality issues (turbo seizing). He is a big Garrett distributor here who has been in the turbo business over 30 years and was pretty embarrassed about the deal. Some people have a good luck with the turbos, but that is the problem. The QA of the manufacturer is horrible.

The stock S5 turbo will be able to make a maximum of about 275 HP.

1991rx7vert 06-05-08 12:34 PM

i guess thats the way i need to go for now...I just need to find a used down pipe....or I may just go to nappa auto, or auto zone...

Coltboostin's running twin China's on his car, haven't heard anything break on it yet.

1991rx7vert 06-05-08 01:13 PM

what would make the turbo fail??? other than maybe the bearings???? or the housing cracking isn't that rare??

Punished 06-05-08 01:34 PM

Actually: Those ebay turbos. XS in particular make very good housings. It is the internals that fall apart and by fall apart I mean literally the turbo will eat a fin and send it through your intercooler.

What you can do is buy one of the XS power turbos or any of the other Chinese knock offs and send it to these guys: http://www.blaastperformance.com/ . What they will do is rebuild the internals with Garrett parts. So you will now have a damn good turbo for $400 or less. I cant find the actual link to the price for the Chinese rebuild price. But if you go into their t3 rebuilds they have it specified that they have different pricing for it. I thought it was like $175 or $200 for the rebuild.

^^^^ Some have even been glued together.
Just get a Garrett if you want a Garrett style turbo. Don't pay the copycat companies. I see that vendor you mentioned sells Garrett.

To the OP. You are going on the right path with buying stock components on a limited budget. Cheaping out costs you a lot more in the long run.

Interesting. Well a year ago I know they made quality housings. But then again, in the past year the shit China has produced has become even more shit. So gluing the housings doesn't surprise me at all.

Some of them use inferior materials. The cast sections may not have enough nickle content to prevent cracking. Or the seals are a more fragile rubber. Or the castings are very thin at points without a machined inner surface. Basically anywhere money could be saved....On the other hand, some of these turbos seem fine. I know people who have been running China turbos for 5 years and have been happy with the result...Meh, it's a bit of a crapshoot whether you get a "good" China turbo or a bad one. You'll never see one on any of my cars, though.
