ca top mount manifold

[1SlowCA18DET]

is it ok to buy the ssac mani and use another turbo or is the maniforl the problme with their kits?

[knightrider]

thier manifolds are junk, some ppl have no problems, others have lots of problems, the choices however are slim, i would recommend if you do get one, go through the manifold carefully, and check for debris from the welds, then make/modify a downpipe with a flex joint so there is less stress on the manifold.

[c-rad]

I don't understand how a flex pipe helps a RWD car. The motor flexes side to side, not front to back like a transverse. If you use the mount on the downpipe that attaches to the transmission, then you shouldnt have any problems as it makes a 3-point brace and all moves as a single unit.

[sdtouge]

so when you hit a bump, its not like 300 pounds tearing your mani in half lol

[sideways danny]

a flex will help because the mani moves with the engine and the exhaust doesnt

[Not_a_sr]

ive ran mine 4months with no flex just a soild as hell brace to the transmission i just now have a hair line crack on my manifold. and i have done 2 drift events and plenty of practice. i have done nothing but beat the hell ouf of this car since i got it back up, my break in consisted of hot laps around the shop. the only thing i have broke was my KAAZ 2way and thats cause of hotlaps and donuts but no figure 8s.

a flexpipe is just that, a FLEX joint. think of your exhaust as a big *** pry bar, its real easy to crack your manifold when you have a 40 lb exhaust swaying around when your throwing the car around on the track, if you install a flex joint near the engine that force is absorbed by the joint, and not transfered to your turbo, and your manifold, thus helping prolong the welds, because on any SS manifold, its not IF your manifold will crack, its WHEN, some ppl dont seem to understand that. yes some last years without cracks, and some last a week, there are plenty of variables. if you eliminate as many stresses on the manifold as possible you can help prolong the life of your manifold.

on a side note, yes the transmission mount for the exhaust helps, but it also creates a fulcrum for the exhaust, so the sideways force is lessened, but still present.

Even if I have near solid urethane exhaust hangers? My exhaust doesn't even move... lol

[CA19DET]

try holding 40lbs with your arm straight out infront of you, thats what your manifold is doing holding/sharing the weight of the turbo/exhaust... when it bounces up and down and laterally, it puts stress on the manifold...

build a bracket from the turbo flange to the head and one from the turbo flage (underside) to the block that will help allot, i have a friend running one on his MK4 supra with similar braces and he's got a HUGE GT45 turbo on there.. only realised that recently, but his car is has been running that for a while making sick numbers.

[1SlowCA18DET]

i heard it wasnt good to try and brace the manifold, you would only be causing more stress on other parts of the mani. i heard the best way was to make a brace from the turbo to the block, or somewhere on the motor.

[fanta]

I'm fond of this brace:

[knightrider]

c-rad, then by all means since your exhaust is so solidly mounted on BUSHINGS dont worry about a flex joint. i dont care how stiff your bushings are, your exhaust will move. even if your hangers were welded to the frame it would move. lemme know if your exhaust moves when you bottom out your car on the ground, unless your car is stock height i think youve probably scraped on a speed bump or 2.

fullrace manifolds are sex .... SSautocrap is a dutch p0rn ... shat

P.S. i dont think fullrace makes CA mani's

They're nice yes, but I was focusing on the brace.

[yourmomsrps13]

oh well that just speaks for itself i mean look at it.......WORK OF ART

[themadscientist]

what a dinky turbo, must be going for response

I continue to love cast iron for it's durability at the sacrifice of maximum flow.

[CA19DET]

[slownslurious]

so what exactly doesn't fit on the SS top mount T3 manifolds? I need a T4 manifold soon, I wonder if I could just get a T4 flange welded to my SS bottom mount T28 manifold. thoughts?

[tyrannix]

as far as i kno (please somone check me if im talking out my ***)once teh actual turbo starts being large like a t3 or t4, its actually too big to bottom mount (because it would hit the block and not be able to bolt down)thats why you switch to a top mount, so the turbo can actually be mounted....

after that, i think it would be alot easier to switch turbos with a top mount setup, just because you cen unbolt the downpipe a little easier (ratcheting werenches are your friend)

and ..yourmomsrps13, thqat sig is out of control. it takes up a whole screen... you could chop the huge pic down a bit and still have the ashtray effect. and mount the 2 small pics beside it or something

[slownslurious]

well I need a T4 manifold with external wastegate and I really don't see too many out there except for SS's offerings... there is that nice greddy one up on ebay and I could get the flange rewelded, but it doesn't look like it has much of a chance of clearing the steering shaft.

[themadscientist]

HKS makes a cast iron top mount T4 manifold. I have two and they are very nice. I suggest you get one of those, they are bulletproof.

[iliketocrash]

i'm pretty sure the SS autocrap manifold has two sets of holes drilled in the flange, one set for t3 and the other for t4. at least mine does.

do you have any idea if the hks manifold will clear the master cylinder on a lhd car? excuse my ignorance if it's an obvious answer. also, where could i snag one of those things if it does fit?

[themadscientist]

I dobt it will. The HKS kit uses an on-center T04 and the downpipe will likely hit the MC.

[slownslurious]

tms- price range on one of the HKS units, and a source to purchase one? if you have two, maybe you aren't using one *cough cough*lol

[slownslurious]

or alternatively, anyone think this would fit in a left hand drive car?

http://cgi.ebay.com/ebaymotors...%3AIT

I don't have AC and I could probably get the wastegate flange rewelded. The price certainly is good. No one else bid on that!

[Not_a_sr]

how many people were seriously intrested in the top or side mount log style manifolds like the one i made for my car? if people want them i can make a few of them here very soon.

[themadscientist]

as far as i know they have not made them for a few years. That is why I have two I won't sell mine but I just saw one in a local newspaper that an American is selling. I'll be back!

updatemy mistake it was a trust stainless one CA18det Trust turbo manifold $200. E-mail [email protected]

[zero_gripS13]

ok honestly how much more flow would u get form a ssac peice of shat compared to a ported stock cast mani???

thatd route ill probably take, i also like the strength of cast..ill just have a macine shop port it aand clean it up to flow more...i doubt as much r&d goes into the ssac mani as people think...they probably just mocked it up to route the thing then welded then port match and called it a day, they didnt focus on flow...or atleast probably not.

[iliketocrash]

there probably wasn't much if any r&d at all when it came to ssautocrap making their manifolds but they're the only ones i know that make a top mount mani for my engine so my t3/t4 will fit. that's my view at least.
