Turbo Exhaust Manifold - Where To Buy?; HELP!

Hi Everyone...

I have a bit of a problem in that I think the exhaust manifold on my Tezza has cracked. :( What the worst thing is, is that it has an aftermarket turbo on it - as I have found out in a previous post - it is identical to an Apexi ax53b60 turbo.

As I am a real n00b to this - where would I even start to look for a replacement manifold that will suit?

I have tried google, but nothing found so far. that's not to say my search terms are all wrong.

Is there anyone who can point me in the right direction?

Thanks

Oh dear thats not good!

I assume its mandrel bent SS?

Go take your manifold to a fabricator that will put in a decent collector, tell him it needs to be the exact dimensions and made of steam pipe and bobs your uncle.

Be prepared to pay though!

they are cast bro, its a apexi turbo kit. i can put you onto a guy here in feilding who could weld that crack up properly for you, just because its a cast manifold doesnt mean it cant be fixed, dont let anybody tell you that crap, it can be welded and fixed.

Have you seen it? Takes a hell of alot to crack a cast manifold and if that is the case Its probably not an Apexi item.

Yea cast iron cracks can be fixed but the quality and the price varies. Generaly speaking you would need to pay a fair bit to get a turbo manifold fixed for two reasons.

1. Cast iron welding is extremely specialised and every job needs careful consideration and planning.

2. Because its a turbo manifold it needs to be repaired with the highest quality workmanship or your going to have the same problem 6 months later. Keep in mind turbo manifolds heat very rapidly and unless the metal is uniform all over it will expand and contract differently around welded joints which could cause the crack to expose itself again. Then there is the huge pressure which can find the weakest link in any job.

TBH your much better off fabricating a new one made from tuned length steam pipe. Job done....

you make it sound like its a hard job! and i know it wouldnt cost too much at all! the guy i know is a specialised welder, he used to be my boss and now owns his own engineering business, with more than enough experience and welding tickets to do the job properly and he is a kiwi so you know the job will be done properly. :P

making a new manifold is not cheap and whos to say that wont crack eventually??but yeah also not worth the hassle or power gain for a street car.


also just because its a apexi item thats made in japan doesnt mean that it wont crack, have you actually seen an apexi manifold in person??? i have as i own one and i can tell you they arent all that great casting wise, the turbo is not supported with a bracket either, nor is the exhaust at the turbo end so theres alot of work the manifolds doing holding things along with getting hot the cold on a regular basis. so i am not suprised if it has cracked..

His manifold is a cast unit but quite an odd Netz one:

Welding will do it you want to do it quickly and painlessly, SR20DET OEM manifolds can crack and is commonly welded however if you want to donut properly get a custom steam pipe setup done through someone like Sinco r similar, love their manifolds!

those numbers are the same on my apexi manifold and everything about it looks the same except for the netz bs on it. its definately a apexi kit on his car, earlyer version to my kit tho.

Thanks for the replies guys, Its good to know. I have taken it into an exhaust place and they don't think it is a crack as it's not in any of the usual places, but seem to think maybe something to do with the gasket or perhaps one of the studs has stretched or broken causing the manifold to leak only while it's cold and seems to sound OK while it's hot. Problem being is that to get at it, the turbo has to be taken off to do it which makes the labour costs shoot up quite a bit.... bummer. Sometimes I wish I knew what I was doing with this stuff, then I could look at it myself. But, I chose IT as a career....

There is an exhaust manifold fabricator in Palmerston North too that makes them out of steam pipe for race cars, stock cars and the like. he rekons around $900 for a new manifold if I need to go down that road.

If it is cracked, I will flick you a message Maccabro about your mate if you don't mind.

Cheers guys

$900 bucks seems like a good price as long as you get a decent collector. Tuned length steam pipe makes all the difference to spool times :)

Im an electronics eng (ADNG) and I do 99% of the work on my car. Started out with a cheap celica that I ran into the ground and made some mistakes on but ill never make them again! Its all about having a go, getting the right tools and asking the right questions.

If I was to change the exhaust gasket I would start by removing my O2 sensor from dump pipe, unbolt dump pipe, remove oil lines and tie up the oil feed to prevent oil spilling everywhere, remove intake piping from turbo, remove water lines if you have them and tie them up somewhere high, unbolt turbo from manifold unbolt manifold from head (engine) replace gasket and assemble in reverse order replacing every gasket along the way including banjo crush washers unless they are copper then you can just anneal them (rookie mistake)... Done and you just saved yourself $300 bucks labour.

yeah mate, no problem, pm me if so. i could posibly help you with pulling your turbo off etc if needed. its a simple job, and i have a special spanner made to get to the [f**k]en prick of a nut underneith the down pipe where it bolts onto the turbo.

if its just a gasket well then thats a easy fix.

i build my own manifolds im a light fabricator hears one i built 6months ago for my 3sgte conversion its got a full merge collector steam pipe runners and its all within 3mm of being equal length i also made oval to circle trasitions were it comes out the head hears some pics

i plan on building them if you guys one hear are keen...

Im a mechanical engineer, admitedly I have not done a lot of fabrication particularly in recent years, but i do know enough to say if you can measure a fabrication like that with all those sections of pipe and welds within 3mm you are doing bloody well! :D

and the diagnosis is........ a cracked manifold!
