Hey,

I'm going top mounted turbo on my car and found these cheap (chinese I'm presuming) mild steel manifolds. Anyone here had one?

What are you opinions on them?

Cheers

a well known reputable manifold is sub $1200

the 6boost one's are $1200 ish

hks ones are $1200 ish

you expect a cheap knock off @ $400

to withstand 1000deg+ EGT's

hold the weight of your turbocharger

and for it to perform?

good luck :D

What's the thickness of pipe, flanges???

Sinco Customs makes good quality top mount steampipe exhaust manifolds in NZ -

http://www.sincocustoms.co.nz/view-product...p%20Mount%29/16

10 year gaurantee to not to crack. Also made of 3.7mm thick steampipe that keeps heat in and exhaust velocity up and 12mm flanges that won't warp. 20-30kw gains with higher boost levels.

Yea, well we can't all afford expensive manifolds so trying to get as good as I can for my price range, just wanting something better than the chinese stainless manifolds as we all know what they're like.

Not too sure to be honest SKYPER, have asked the seller a question on the auction. How much are the Sinco ones? Don't have a great deal of money to spend on it

By the time one cheap manifold dies, and you replace it with another cheap one...

The decent manifold works out cheaper

I would just get a chinese one and mount the turbo and exhaust correctly, if fitted correctly they often last ages. Its when they get fitted with the weight of the turbo and exhaust hanging off it that they crack

Apart from using a Gibson Motorsport style hanger/brace, how do you avoid the weight of a turbo hanging off the manifold?

Support it partially with the exhaust. IMO it is usually the exhaust that causes the problem, imagine the force that an unhung exhaust puts on the manifold as you are bouncing along in a lowered car.

I also machine both manifold surfaces before fitting and whenever refitting if necessary.

Poorly hung exhaust systems will often be accompanied by vibrations so shouldn't be that hard to spot. Agreed, the type of leverage they can place on the turbo and manifold are likely to cause problems.

One thing I see as a possible plus for this particular manifold is that it's not stainless steel. Perhaps not as fatigue prone either?

It's a bit of a judgement call, but at the price point perhaps worth a second look. I do agree that the other named brands are known quantities and come ready to bolt up, not requiring extra facing or bracing, or internal finishing that costs time and/or money.

Sinco Customs NZ$1000 to $1200 depending om wastgate configuration.

    • Yeah I've had too many issues with knock off's on the BMW's. I don't want to do a job twice or more because the parts are shit.
    • I read this and thought "ah! I will do this scissor jack on the tow point thing!" I just use my floor/low profile/costco jack and lift the car up by the tow hook itself, then slide jack stands under. Never thought about using scissor into floor jack combo :p
    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
