yes i know thats a s4 front cover i already changed it to an s5... they thought the motor was going in a s4 but it still got changed for free.... motor looks a lil different sitting in my car.... also has an underdrive pulley.... still non the less a nice motor

 

Who built it? Streetport? How high compression are the rotors? What turbo are you running?

 

Is that a stock flywheel or aftermarket??

 

Sweet! I like it!

 

clutch and flywheel : OS giken twin plate
Motor: done by R&R rotary in upland GREAT guys!
Mods: BIGGEST streetport they could do, and 9.7:1 rotors

turbo: S5 turbo... ported wastegate.... t04b compressor .60a/r

 

Looks nice dude, let us know how it runs

 

Damn you, hah i want pictures of the street port i need ideas... Nice motor though tell us how she runs once you break her in

 

nah i dont got any pics of the port ... sorry

 

The turbo says it a t04.

 

high comp rotors + bigger compresser + stock WG = creep like a **** even if ported

 

I agree w/ Scott above

In addition to ported wastegates my '89+ 60-1 hybrid was bored for T4 "O" trim exhaust wheel clipped 15 degrees- much more free flowing than stock exhaust side.

BOOST CREEP to ~22psi by 3,500rpm (low comp rotors)

Glad my pop off valve saved engine.

I went nutty on stock WGs porting them to max and externally venting them out backplate w/ 2 1/4" hole, maximizing flapper throw etc.

"Only" creeping to ~17psi (warm day) total now.

I am currently adding a HKS 60mm external WG now (43% bigger area than bored holes I have now).

Save your engine and put a "real" turbo on it- I will soon, I just have to see what HP I can make of "stock" turbo.

 

yea thats what im worried about... but we will find out soon.. i ported the wastegates to the max... i got an idea in mind but ill keep it to myself till i find out.... plus im only running 2.5 all the way back... not stright 3 inch

 

oh plus im going to modify the wastegate arm move were the rod connects to closer to the pivot point so i get more movement and also make the wastegate exhaust gases divorced like a previous member did... hopefully with the wastegate opening twice as much and having its own vent will realive all the pressure and keep my boost below 10psi

wait i just reread BLUEtII's post... is that a s4 turbo or s5???

 

Looks good,

 

As I said

In addition to ported wastegates my '89+ 60-1 hybrid was bored for T4 "O" trim exhaust wheel clipped 15 degrees- much more free flowing than stock exhaust side.

Pics of it adapted to 60mm WG in this thread. Still boost creeps . I think it goes back to Bryan for more clip or "P" trim wheel.

Yes, that exhaust should help keep boost creep in check- as well as a spool-up and power...

The pencil pipe exhaust is not staying on is it? I can't fathom why you would do a large streeport, dangerous high compression, a larger compressor and choke it out w/ a puny exhaust.
