It's probably posted alot, but will a S5 turbo bolt on a S4 engine? I read some where it can but you need the s5 manifold. Also how much is it to rebuild a s4 turbo and a s5 turbo both stock? Also i heard the oil feed lines wont fit is that true also and if so how do you get by that?

 

Yes it will ,and,yes you would use a s5 manifold , its because the s4 exaust manifold has one smaller exit hole, and is mounted slightly forward on the engine but the s5 turbo is centered on the exaust ports. The last time I had a turbo s4 rebuilt (5 years ago) it cost me $850.CAD, for the lines either make up a line locally to fit (turbo oil line )or buy one that you can use off E bay, of course you could replace the stock turbo with a ( inexpensive Ebay T3 T4 Turbo with internal, wastegate , for ease of instalation,and either adapt your present exaust manifold, weld on t3 flange,or replace it, with a manifold with a t3 exaust flange on it,either way you will see a marked improvement over the stock system(ps make sure you test the wastegates to see how much boost they are set for, and of course clean and update your fuel supply to match your turbo choice

 

yes.

last I talked to Brian at BNR supercars he was charging 350 for rebuilds, charges a little more to port the wastegate so you can control your boost, very recommended if you're opening up your exhaust

either manifold will work, as long as you don't mix turbos
so S4 manifold with S4 turbo, S5 with S5

IIRC Oil feed lines are the same across all of the generations..

 

they're both the same CHRA so the rebuilds are identical, the only differences are that the bolt pattern is different so the manifold need to follow the series of turbo.

the oil feed and drain lines also need to follow your series of motor but they will bolt to either turbo the same. the S5 feed line off the engine is a different nest and has a pipe for the boost solenoid and is shorter than the S4, the drain line moves to the front of the timing cover where the S4 goes straight into the side of the timing cover. both of these are 2 pieces and you will need both pieces(4 oil lines in total) from the S4 for an S4 engine to bolt to the S5 turbo and vice versa if you have an S5 block.

 

how would u reweld the manifold? mine looks liek a soild piece. I seen 1 on ebay that fits a rx7 n comes with adptors. ok soo 350... It b more cost effective for me to buy a ebay turbo and what not for now just to get it running. But ask Brian how much it is for porting waste gate. My exhaust is very open 3" DP no cat 3" all the way back.

I'm going to see whats better/cheaper. + I plan on upgrading turbo down the road so i gotta factor in that 2.

 

no, an ebay turbo requires a manifold, turbo, downpipe and wastegate and fabrication work. it will also affect the airflow of the engine requiring some sort of standalone or piggyback engine management system. in short, upgrading the turbo(lol, did i actually say that an ebay turbo is an upgrade?) will cost no less than $1k even if you do it the strictly cheapest as possible, those turbos are also garbage chinese knockoffs which will fail sooner than later.

your best bet is buying a used but good turbo that came from a TII, you can usually find them in the $100-175 range or less.

 

well manifold i found 1 that fits like i said and comes with adptors. I have a Rtek 2.1 or w.e the latest is. The downpipe my neighbor can use his plasma cutter n reweld the dp flange, I'm running stock 550CC. I do have a forge boost controller and as for wastegate I'd do a used 1 for cheap if i cna find 1. Now the fabrication work thats where its gonna be iffy.

i was looking at this manifold http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT

and these turbos

Looks really cheaply made- http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT

or this 1 http://cgi.ebay.com/ebaymotors/T66-T...item5add205886

http://cgi.ebay.com/ebaymotors/GT35-...item35ad7a627e

 

all those turbos are cheap chinese crap turbos. is it worth killing the motor when the compressor wheel disintegrates? they're basically T04B knockoffs, which you can buy a real Garrett T04B for the same or less and have a decent quality upgrade turbo. or if you're really handy you can use the T04B and hybridize your stock turbo since the Garrett T3 turbos use the same components and have a direct bolt on turbo upgrade.

 

.
ya im not handy and id rather not mess up my turbo. and i dont wish to blow up my engine....lol so ill look into that

 

holset turbos are they any good? and which 1 would b a upgrade i seen them on ebay but some r 4 disels, does it make a difference

 

dude, you really need to start researching things more and understanding turbocharging before you swan dive into the shallow end of the turbocharging pool

 

Before you say it; the SEARCH function would be considered a research tool, not the NEW THREAD function.

 

^ Classic!!!!

 

^that was music to my ears. There's a reason that this forum has an entire section devoted to single turbo's. Save yourself some time and money and send your turbo to BNR, seriously with these kinda questions you need to read up and hold off on trying to do some egay turbo build. Which BTW will make you look like a complete idiot. Not trying to flame you but building an ebay turbo kit is pathetic and insulting really. There's literally almost a decade worth of info on this site.

here ya go buddy do your own homework from now on
