I finally installed freshly rebuilt motor into my single turbo FD
This is only the beginning

I am sorry for not posting pics of internals (porting) of engine but I will as soon I can find them!!!

 

My plans include 60-1 turbo which I already have
.7 a/r compressor
.96 a/r turbine non divided with a p trim
future mods:
-custom manifold with tial 46mm WG
-kgparts sec fuel rail with 1600 cc injectors
-EMS Apex power FC or Haltech E6K not sure yet
My goal is to get 400 RWHP ???

 

Just pic up the HKS manifold off of Aithun here in the for sale section. It is cheap and will work well for you. Then use the HKS 50mm wastegate. So for around a little less than a grand you got what you want.

Edan
Are you talking about the HKS cast manifold??
I just want to make sure what works best for me
For less than a grand that is really not too bad.
Thanks

 

No, it is the HKS turbular....

 

link coming...

p.s. this guys is a good guy, so you'll get what you pay for.

same manifold as in this thread

Thanks Edan
I will contact him
the manifold is divided, will that affect my turbo because it is non divided?

I was looking into this manifold but dont know the quality
I contacted them and said manifolds are now SS.
For $500 that is not bad at all.
Which will flow better/

 

shouldn't... you may want to rethink going with an undivided turbo. But get the manifold, so at least you can change out the turbine housing and get a divided housing...

Go with what is proven, spend the couple hundred more, unless you got money to blow.

Thats what I have learned.

Edan

 

Why should I change to divided??
I would think divided turbine would be more restrictive depending on the manifold.
I can always change my turbine @ no charge from my friend but I still dont see whay
can anyone please explain??

 

The divided housing will give you a 500~600 RPm faster spool, without affecting your top end that much (maybe a percentage point or two?)

 

Divided is supposed to give you boost sooner (lower RPM). I am not sure what the downsides are, if any. It should be okay to run a non-divided turbo on a divided manifold, but it makes sense to take advantage of it by running a divided turbo.

In other words nondivided will give me more turbo lag.
I can always change my turbine to divided I got the turbo through a friend here in Long Beach and will replace my turbine @ no extra charge.

will a 1.00 a/r do? and if so do they come with a v-band like my .96 turbine?

 

yes, & yes. Should work well for you... 15psi around 4000rpm. for 400rwhp on pump gas (<15psi of boost) you'll need a decent street port. With stock porting you'll be closer to 340 or 350rwhp at 15psi.

 

thats inciteful. hahahaha, i have a 60-1 w/1.00 a/r hotside on an xs cast manifold. . . untuned. been wondering what ill have to do in order to hit 400rwhp. hopefully, i will. . . i have a streetported motor. . . dont know how aggressive though. . . . geh

It has been a while since I worked on my car
Well I managed to eliminate my P/S, I actually did my own I bought all the parts @ baker precision and it only cost me $15.43
Just thought I would share with you guys

Not a chance on the turbos, and manifolds being discussed. We have seen hundreds of dynos on this forum, and as far as I can remember, nobody has done a back to back test. That said It is in theory a better way to go, but maybe by ~200 rpm from similar set-ups I have seen, more than that you would have to show us if it really means alot to you .

I've seen back to back runs on Supras(divided manifold to undivided turbo, vs divided manifold to divided turbo), and there was not more than 150rpm difference in spool. the top end was about 10% higher on the divided tubular vs a cast manifold though. The initial spool was actually slower with the tubular, but about half way into the curve the tubular began to gain an advantage. Sort of a moot point since you cannot hook the power up with anything less than drag radials anyway. Carl
