Post by adamky »

Did you guys do any prep work to the manifold to allow for thermal expansion??

Such as cutting the flange between runners, or enlarging the bolt holes or both??

Also, are you guys running a flex section in your downpipe??

nope and nope. It works fine surprisingly. Heck, the stock setup ddin't allow for any flex, i figure this one should be fine.

Really? I would think heat wrap would not be good for such a thin walled manifold....

How long have you been running that setup???




So, from the looks of things, I should be good to go with just a flex pipe. Cool.

SSAC sucks on S13 DOHC's, Doesn't clear the BMC. I have a T3/T04e turbo and Im just about done with my install but know i have to buy a new manifold. Sucks. Found out if i want to keep the T3/T4 manifold i have to weld a wedge flange in order to be able to clear the BMC which costs more money. Oh well, you live and learn.

I've heard bad things about the T3/T4 mani they sell. The T25 mani is one of the few I have seen that hold up well. Maybe due to less weight and stress on the main....?

If you are talking about the top mount, the walls arent thin. In facti think its a very sturdy manifold. Ive had mine on the car for over a year with LOTS of abuse and whatnot. no cracks at all.
you can use heat wrap on just about anything you want. I wouldnt think it would hurt other than causing moisture to stay on the mani, and possibly cuase a problem. But if its dry, its no problem at all.


Personally, Id rather buy 6 150 dollar manifolds than 1 800 dollar manifold. Cuz the truth is...even 800 dollar manifolds have problems, and can crack too.
So you could buy 6 manifolds before youd buy one high dollar one. I dont know..i guess im just aprtial to the underdog(the less expensive mani's)

im about to crack (no pun intented) about 1000 miles this week on the manifold

The clearance suck but that because I have ABS on my s14-but I have a heat shield so its no biggie

Does anyone know if there is any fitment issues with this manifold on the S13 DOHC?

If anybody has fitment issues it because they have a 4-bolt exhaust housing, ABS or severly sagging mounts.

Absolutely. I was just wondering if any prep work would be benficial. These mani's have had problems in the past and I would rather be safe than sorry.

so the clearance would be good with say the t3/t4 manifold with the turbonetics t3/to4e 50 trim .63 a/r from jgs?

It fits on mine just fine. I have a T28 bolted to it.

What does not fit is the downpipe to elbow. Theres about a 1.5" gap between the 3 bolt flange on the elbow to downpipe. Basically the downpipe hits the bottom of the car and prevents it from being able to bolt op to the elbow.

Ive tried the SSAC downpipe and Megan downpipe both hit the bottom of the car and make it come up short.

One question I have is, is the CA18DET elbow the same as the SR20DET elbow? If they are different then thats my problem, but everything Ive read say that they are the same.

As long as it has the 5 bolt exhaust housing it will.

^^ yes the ca18 turbo extension is way different than the sr turbo extension.
the ca18 is angled completely differnt and sits higher. When i had my ca18 i had to modify the sr downpipe to fit.

My Megan DP bumps the floorboard...next time I have my car on a lift, I'm taking a hammer to that chit. It didn't touch on one motor, but the last two it has.

Thank you so much for that answer. EVERYONE, has been saying otherwise. But what you just said, shorter and angled, is exactly why my DP wont fit.

All you guys having downpipe problems.... is this on S13's only, or S14's as well?

I think the people who are having problems (myself included) are using the wrong elbow.

SSAC labels there turbo elbows as "fits 89 thru 98 180SX and Silvia"....which apparently is incorrect.

The few people Ive seen that has actually bolted up with no problems, such as billklinevt, used Megan racings elbow/downpipe combo.

That's weird. I noticed in Jordan's cheap turbo kit post that he didn't mention having to alter it. Maybe just some of them don't line up properly...???

I didnt do any prepwork to mine. I juts bolted it on and rode out. I heard to cut the flange but the flange is thick as crap on mine and has no warpage, so I left it.

Only for the DOHC s13's running the t3/t4 turbo's. Turbo wont clear with the SSAC t3/t4 top mount manifold. The Brake Master Cylinder is in the way because of the certain angled position of how the manifold sits. Have to either buy and weld a wedge flange to weld on to fix the angle or get an s14 brake master cylinder. My opinion, get a log manifold if your going to run a T3/T4. I did. Now i have to sell SSAC Manifold. Any takers let me know.

what kind of exhaust housing where you running 4bolt or 5? i have heard it clears the BMC with a 5 bolt such as JGS offers.

It's a 5 bold turbo and the JGS turbo 5 bolt clears the BMC with their manifold but not the SSAC mani.

^^ Thats odd. You're like the only person in the universe that I've heard of that couldnt get a 5 bolt to clear. Unless you have ABS.
