AH IC, thanks JC.

 

no prob, keep us updated jimster

 

I have a To4e w/58 wheel the exhuast is an .81 on a stock S4 block getting about 300 RWHP @10psi and hope to get 350RWHP@14.5 psi. it pulls pretty hard from about 3k to 9k in 3rd an 4th gear with full power by 4k-4500... kinda wish i had a little bigger turbo

 

That's right about where I want to be, in the 300-350 RWHP range. The turbo is on it's way and should be here in a couple of days. I'm kinda having a hard time locating a .81-.96 tang turbine housing though. I emailed Turbonetics and got nothing back. I keep scouring ebay and as many turbo forums as I know of hoping to find one for sale.

 

yes i am still trying to find a .81 or .96 housing. they are rare to come by used...

 

What is the real performance difference between a divided and undivided housing beside the obvious visual difference...?

 

from what i've seen theres not a big difference... i'm even mixing them, using a collected manifold (hks cast) and a divided 1.15 turbine housing...

personally i'd go with the undivided, its cheaper, and there probably wont even be a diffence when the manifold runners are as short as they are on FC's anyways.

ps, didnt you post on the first page that you got the HKS cast manifold? its collected, so you may as well just get a collected to match

 

This guy sells that housing you're looking for! I bought the .96 tang housing from him not too long ago.

EDIT: Of course, after I reply, I just notice you said used. lol sorry bout that!

 

I had pretty much settled with a seller on a manifold, but he decided not to sell it the next day

Oh well, it gives me a bit more time to do some thinking and searching...

 

dead link....

 

Most of the GOOD tube manifolds have long runners that move the turbo up and forward in the bay. Hassan on the fc3s forum made a custom manifold that had almost perfectly equal length runners that were 22" long . The turbo sat completely in front of the engine and the radiator had to relocated a bit. He said the difference was very noticeable, 10PSI @ just under 8K with the HKS log vs 10PSI @5K RPM with his custom mani, both pulls in 1st gear.


BUT, I can't put my turbo that far forward...I'm running a W2A IC in the stock location, so the turbo can't be pushed too far from the stock location without getting really messy with the IC piping.

 

i run the HKS cast manifold and i love it. its cast so its not going to crack, it isnt all blingin inconel or wahtever, but it doesnt matter cause you cant see it and the HKS manifold still moves the turbo up quite a bit in the engine bay... you ever seen an upgraded turbo setup using the HKS manifold?

also, most of the GOOD tubular manifolds arent 200 bucks shipped

 

this was my old setup. hks cast manifold, hks standard wastegate, t04s 60-1.

as you can see it sticks the turbo pretty far up there...

 

Yeah, that's not too bad, I could work with that...some of the other manis seem to push it UP as well as forward. Was your strut bar right above the comp outlet?

 

yes. i think the turbo is out SLIGHTLY further than the strut bar

 

Well, the manifold hunt is not going as smooth as I had hoped. I am looking for a custom divided manifold and have found rx3mist and autolabonline. I can't find a cast HKS mani for the FC, but I did find an HKS divided for the FD...does anyone know if this will allow a T04B to fit w/o hitting the LIM?

 

have you considered getting a BB turbo? you said you wanted to be mostly using the car for auto-X... and arent you off and on the throttle alot driving like that?...

if thats what i was doing, i would look into a BB turbo... whatcha think?

just thought i'd throw that out there...

good luck, im doing a similar setup

cheers,Dan.

 

Yeah, BB turbos are the ****, but they are also big $$$. I will probably upgrade to a full BB turbo a bit later, but I gotta take baby steps. My first year teaching salary doesn't permit me to drop an assload on my fun car.

 

Except that BB turbos are around twice as much afaik. If you're rich, sure... it's great.

 

autolab is about 5 miles from me i know everyone that works there. they arent rx7 specific but i believe they have made one or two FC manifolds (and i think the mockup was even made on my friend's 10AE)

if i were you i'd get on ebay and get the greddy cast T4 manifold. what i was saying about the divided manifolds it laymans terms: dont waste your time or money on it. greddy and HKS manifolds pop up on ebay regularly. my HKS manifold was 200 bucks...

and as far as using the FD manifold on the FC, you have to use a block/manifold spacer to get the turbo to clear the LIM so its kind of a hassle.

cliff notes:
1. get a cast T4 manifold. it wont crack and its 200-250 bucks (see also, half the price of the FD divided and autolab fc manifolds.) when it being divided really isnt worth the extra money it costs.

 

I thought the FD mani's wouldn't fit w/o a spacer, but the seller insisted that it'd fit.

I saw that gReddy mani on there, but it's 300...I'd like to find the HKS for 200, if possible. I don't need the car to be back on the road until spring, so I'm not in emergency mode.

Thanks for your help jc...

 

I got the gReddy on eBay...the seller dropped the price for me quite a bit since I didn't the DP and other stuff for a DSM. I might be able to get this thing going before the snow flies...

 

cool, keep us up to date!

 

Good to hear it Jim.

 

The manifold arrived over the weekend in perfect shape.

Is the 4 bolt WG flange on the greddy manifold the same 4 bolt pattern as an HKS WG? I need to figure out what WG fits this thing...
