My IAP manifold cracked.

^^ LOL, well I wasnt roll-calling or naming names, haha

In most RWD applications, it's not necessary to use a flex joint. FWD cars twist perpendicular to the exhaust where as Longitudinally mounted engines twists parallel to the exhaust. It really depends on how much movement there is and how much movement the exhaust mounts allow. How well the exhaust /downpipe fits can also affect whether a flex joint is needed or not.

No problems here "knock on turbo???" I've put the mani through h3ll countless times, It's about the only thing that hasn't gone bad on me yet...

[lrb_2000]

Yeah well.. when you're a dumbass like me, stuff like this happens... My exhaust was only held on by the last 2/3 hangers, and then the turbo.. haha. i'll do it right this time.

[lrb_2000]

Well... I got a 8" section of flex tube in my downpipe, the exhaust is held up by really good now.. I welded up them manifold in all the spots that it cracked at.. and resurfaced the flange.. I'll get some pics of it now. I was told not to slot the runners because it would put more strain on each individual runner, rather than a whole. I also filled the motor mounts with 3m window weld, so it shouldn't torque as much.. hopefully there's a lot less movement and I don't have this problem again.

Well, I hope it holds up, but I won't be surprised if the flange warps again.

[lrb_2000]

well ****.. I just don't want to mess it up.. should I slot the flange or not?

[WDRacing]

ALways slot the flange, whoever said it will stress the runners more is wrong. Each runner has two studs holding it, by not cutting the flange...does this increase the amount of fasteners somehow...I'm thinking no.

[lrb_2000]

alright.. how wide should the slots be, 1/4"?

[C-Kwik]

It doesn't have to be big at all. Pretty much as wide as the blade you use to cut it should be fine. Keep in mind, the manifold expands outward. The slots will grow in size with the expansion of the entire manifold. The slotting just keeps the flange from preventing the expansion.

[lrb_2000]

So I got everything installed. I must have had some crazy leaks. I didn't change my setup at all, and it hit 15psi right away, which it previously was set at 10psi, so I had to lower the boost a little... the turbo spools like crazy now. I used all new gaskets, and metal ones for the turbo. Everything bolted up good without having to force it. Also, filling those motor mounts with the window weld helped a lot. The engine looks a lot more smooth, and doesn't torque as bad now.. I can kind of feel the extra vibrations in the car, but I have coilovers and such, so I don't really care. I hope it holds up this time. I'm going to get some videos next week probably.

[daconkiftador]

hell yeah, thats good news, cant wait to feel the difference!

[Kaleo55]

Hope it works out for you. I have a IAP mani that's about to get installed on a newly built KA. IAP offers a 1 year warranty, and they do recommmend using Megan flex head down pipe. I also have the IAP downpipe from the turbo, so hopefully it's all work together as I am hoping to run at around 15 psi...good luck.

[WDRacing]

Coatings sure make things look sexy...nice ride byt he way K.

[lrb_2000]

damn, that looks nice.. what turbo do you have there, looks like a turbonetics

[WDRacing]

My guess is Precision...

[Kaleo55]

Yep, it's a Turbonetics T3/04 along with Turbonetics Evolution wastegate.

[lrb_2000]

FTW! haha. nice.. I hope to see lots of pictures and stuffs when it goes together!

[daconkiftador]

PWND.

[lrb_2000]

So I figured I update this.. it's been two months since the manifold cracked, i've been running anywhere from 8-14psi, and it's held up great. I'm going to have to blame the cracking on myself, due to me getting ahead of myself and hurrying to much to get it done. My exhaust/downpipe was pulling on the turbo pretty bad, and the flange on the manifold was acually warped before I put it on from the previous owner, and I didn't pay any attention to it. But everything is good so far, and I plan to be using a GT35 on my built motor and looking for over 500whp.

[NateDogg]

Sweet, I love white 240's with the 180 tails..

Nice car man post up some vids if you can

[lrb_2000]

Acually, they're ebay tails that I painted haha.. here's a few videos ...

this one is at 10psi..http://youtube.com/watch?v=qjRlh4GrW_U

and this one is just a few races..http://youtube.com/watch?v=mHx6lE5KmEA

I was running about 12psi and keeping up pretty good with a sr20 running 20psi on a t28..

[WDRacing]

Glad everything worked out for ya man...keep us updated on the progress. I'd like to see that new turbo in action.

WD

[lrb_2000]

Indeed. I can't wait for the new setup either.. I'm hoping for a big tax return to help out a lot.. I'm pretty much finished with the motor, i just need the turbo, bigger injectors and my ecu tuned...

[WDRacing]

Have you considered the MSII yet? I keep reading up on it. I very well may go with that setup when I rebuild my S14. Cheap and user friendly are big bonuses in my book. Not to mention the support it has, I can't believe the amount of people that use it.

So you finally got a set of rods? I thought I might have my DE motor built before you finished yours.

[lrb_2000]

no, but I have money for them.. hahathat's not fair, you already had a built motor, arent you using the the internals from it on your DE?

I haven't acually, i'll have to look into it... do you have any good links I could take a look at?

[WDRacing]

Dude, I have a brand new set of Pauter rods and Ross pistons I'm unloading. I'll mark them down 100 each from the advertised price. Shoot me an email if you're interested at all. I haven't listed them [email protected]

[lrb_2000]

I emailed you.. and just realized there's a writeup on megasquirt.

thread jack

lrb_2000, I have a question about your kouki tail. Did you use 3 pieces or 4 pieces of the tail light? There is a long piece that goes under both light and the center garnish. Did you have yours painted or you didn't change it?
