hks cast manifold-clearance issues on 1st gen?
i'm doing a 60-1 turbo upgrade on my 1st gen which has a S4 13bt. My question is will the hks cast iron manifold clear the frame rail on a a 1st gen or will mods be needed to make it fit. I find out myself but the stock turbo is still on my car.
If anyone who has experience with this knows I would appreciate the info on it.
Thanks

It will fit just fine with a tangential turbine housing. An on-center housing turbo will hit the frame rail. I am running a T-66 on this manifold in my first gen. The GT wastegate has a v-band flange I believe but the manifold is set up for a standard HKS 40mm. I will be selling my setup soon (manifold and wastegate). PM me if you're interested.

I'm running the 40mm. The manifold has a 4 bolt flange designed for this wastegate. I assume you could make an adapter if you wished to run a wastegate with a different flange.

I want to be around 11-13 psi.

Also what boost controller are you using???

Here is my scenario/setup so you know what I'm after:
85 GSL
S4 streetported 13bt
T04E 60-1, .70 comp, 1.00 exhaust
custom fmic
Hks cast manifold and Hks standard 40mm wastegate.
Microtech MTX8
dual bosch pumps
550x1600
custom surge tank
blitz bov
I'm aiming for around 340-380 rwhp at around 12-13 psi (+-) and as much as 15 psi MAX.
I've been told 40 mm for the wastegate is plenty by some and too little from others and that I should get something a bit bigger.
I've also heard if you don't have a good boost controller you will get creep. Then i've heard if you run lower boost you need a big wastegate to bleed off more exhaust gases.
I've also heard the hks 40mm is good to a little over 500 engine horsepower so I should be fine.
I know the 60-1 is a mid sized turbo so 40mm should be fine but i've heard so many different things from diff people its getting ****** frustrating. Who do I listen to? I want to get it right the first time.

1) Increase overall peak boost
2) Increase turbo acceleration and therefore fatten up the torque and horsepower bands of the car
I like the setup and, although I don't agree with the EFI system, I think it's a much better choice than trying to piggy-back a stock system to death just to find that it won't work properly. It should make good power; definitely overkill on the fuel system.
One more thing I forgot to mention -> the wastegate (HKS 40mm) will work beautifully with that turbo setup and power output.

Thanks Brian What wastegate/manifold are you using?
What part of the fuel system do you think is overkill? the 1600's or the dual pumps? One will be a 500hp bosch (not the 044, 984 or 910 I think) and the other has no name on it but it supported 271 rwhp a few years ago.
I've tried to source some 1200cc secondaries but cannot find them anywhere. I am reluctant to get my 550's bored out to 1200's. I know 1200 secondaries will provide enough fuel for my needs.
Why dont you agree with the efi i chose? Your a haltech guy right? I got it for a good price...that's why. Nothing against haltech

On the "fuel system overkill", I mean that in a positive context. It's definitely a good thing to have enough pump and fuel volume backing up the injectors so I wouldn't change what you've got. The injectors, though, I could recommend something like four 720's or a pair of 720's and a pair of 1200's. This is *alot* of gas. You can do wonders with that.
On the EFI system stuff, I made the comment not in the interest of starting another fight between Microtech and Haltech but because my own personal experience has yielded that the E6K is a better choice. In any event, both will definitely do a better job than what the stock EFI can do so it's nonetheless a better choice.
