Recieved my Import Auto-Performance Equal Length Manifold

[rn240sx]

Well guys, here is the story:Payment was sent on Jan 2nd to Import Auto performance. I recieved a call from Marc at IAP stating that payment was recieved and it would be NO longer than 2 weeks.I got an email on Jan 19 stating that the Manifold and Downpipe will be shipped out that evening.On the 20th I got another email with my UPS tracking #On the 23rd I recieved my manifold and downpipe...!!!THIS IS WHAT I CALL CUSTOMER SERVICE..!!!

Lets just say i was EXTREMELY IMPRESSED..!! The welds were excellent, egt bung came out nice, ports were matched to head, this thing weighed close to nothing, and the best of all, while installing it, i was able to get to ALL 8 bolts with a socket and rachet..!!!! Unlike the revhard which has to be done with a open end wrench on 5 out of 8 bolts. And not to mention that bottom right nut which has to be removed while HOLDING the manifold in mid air....

I only ran into one problem. This manifold was made using the Deltagate wastegate. I have the Tial 35mm. The Tial 35mm is about 1.5 inches taller than the deltagate. So, i found out that my AC line was in the direct path of the tial.. Not a prob, i just moved it over toward the body frame and bolted it down with a clamp. I did speak to Marc and he said, "ok, Robert, if u would like, send the manifold back to me and i can have it fixed to work with the tial". I said, thats ok, you designed this manifold with the deltagate, I have tial, i can just move the AC line over and bolt it to the frame... DONE..

The downpipe bolted up to the cat with ease. The downpipe did not touch anything on its way down...

Well now lets talk about the wonderful power gains. When i had the revhard, i noticed that the motor was dying out after 5k rpm in pretty much all gears and got worse as i went up in gears.With this new manifold, this motor goes up to redline with ABSOLUTE EASE thru all 5 gears... NO JOKING HERE..!! I mean, it feels like this motor wants to go past 6500 rpm...

I just wana give out special thanks to MARC at IAP for his excellent customer service and keeping me updated on the progress of the parts, and volunteering to fix the manifold to acompany my needs. Marc was always pleasant to speak with over the phone and answered ALL my emails within 24 hrs..!!!

Pics will be up within the week athttp://www.cardomain.com/id/rn240sx

ThanksRobert98 ka-t

Man, I've really been eyeing up that manifold. Its good to hear such a positive review of it. It just seems so expensive though. However, if its as good as you say it is and doesn't crack then it just might be worth it. Keep us updated.

[Nathan]

Did you have to get that damned turbonetics 5 bolt housing too? I was a tool and overlooked that fact so now I have to wait to try mine out It's GREAT to hear of another satisfied customer though, you can thank me later for those ports matching the head

[rn240sx]

Their Downpipe came with the 5 bolt flange attached as well as the bottom side 3 bolt cat flange.. I will have pics up soon this week..

[Structure240sx]

wait so does it sit the turbo exactly the same as the revhard? if it does u'll see my RH for sale very soon

[Nathan]

I dont think it does structure, you have to use either a turbonetics 5 bolt outlet T3 turbine housing, or an on center T4. I dunno what you have, but if it's either of those you'd be set Well, as long as the downpipe worked...it's probably pretty close to where the revhard puts the turbo.

[Structure240sx]

i have a garret to4b on center. i guess it should work since he switched although you right the downpipe might not work but it might. maybe ill have to find out once i have some extra money to burn. for now i need to get some brakes

[rn240sx]

From what I can see the revhard sits the turbo at a 30 degree angle away from the motor..This IAP manifold sits the turbo at about 5 degree's if that.. It almost at a 0 degree plane...Their downpipe has the 5 bolt turbonetics output... Not the Garett 4 bolt.. I believe your on center housing may or may not cause the turbine itself to hit the valve cover...

[fiznat]

if you dont mind me asking, what was the total price you paid?

[Tictakman]

got a cost?

oh ya what rpm do you get full spool rn240sx?Zak

[Structure240sx]

i dont think it would hit but it would be very close. too close for me to pay $700 even if i could sell my RH for a couple hundred

[Nathan]

That mani is 650 to NICO folks. I dunno about the downpipe

[Tictakman]

got price, thanks anyway.

need pics too.

Zak

[Tictakman]

dp is almost 300 i think.

[Nathan]

Did you go to http://www.import-autoperformance.com and go to the manifold section? you cant get a much better picture...I know because I took it

[rn240sx]

Hey Nathan:Are you getting boost surges by chance..?? I now realized that my boost pressure is not staying at 6.5 psi.. anymore. Now it will continue to rise slowly and wont stop.. I had to let off the gas pedal once it hit 10 psi and im sure it wanted to continue..It gets to 6.5 FAST but then it slows down and SLOWLY continues on until i let off... Could it be the design of the wastegate feed off the collector..??

ThanksRobert

[Nathan]

You know, I haven't gotten my car up and running yet but I was worried about that wastegate feed. I attacked it with the dremel and opened it up a good bit, there is plenty of material you can take out without compromising the structural integrity. That feed was the only thing I was a little irritated about, but it only took about 20 minutes to fix. I even did it with the mani on the car, I just shoved rags in the runners, then went to work, letting the particles fall down to the wastegate. Ideally, I'd have been able to open the wastegate and blow them out, but I dont have a compressor in the garage to do it with I just blew the filings out with a can of compressed air, then pulled the rags out and wiped all down in the runners with a tape covered stick. After I was done I couldn't see any filings and feel pretty safe that any tiny ones left will get blown out on startup.

[j-z]

imho that mani is not even near being worth what it cost. look at it, and youre saying that you have boost creep too. that aint good. hmm

[Nathan]

What WOULD be worth that cost? You could expect to pay well over 1000 for a similarly designed stainless mani, something I'm not prepared to do. Manifolds are expensive, especially equal length ones, it's just a fact of life.

[TrunkMonkey]

You know, I haven't gotten my car up and running yet but I was worried about that wastegate feed.

this has been a concern of mine too. i'm convinced this is the cause of the boost creep. if it were me, i'd cut that feed off and mount the wastegate as close to the collector as possible.

1st off, I havent narrowed down the source of the problem..!! I may be totally wrong here. It could be the spring itself going bad.

2nd off, as Nathan said, this is a pretty darn good price considering there is ONLY one more companie out there that have made an equal length manifold for the 240sx... The other companies Equal length manifold can only be used with an internal wastegate. And it costs $800 (stainless is the only option they have).

3rd, this is by far the BEST made, looking manifold out there for the 240sx, why, cause I havent seen that "other" one yet...I installed my manifold in 5 minutes with a socket and ratchet....!!! Thats how easy it was to get to those nuts. My revhard took me nearly 45 minutes with an open end wrench, ONE TURN at a time..!!

And about the boost creep, its not like it spiking really hard past 7 psi... It will get to 7 psi then come to a drastic slow down, then SLOWLY pass 7 psi...

Im not here to talk smack 2 u in any way.... Just expressing my feelings and suggestions...

ThanksRobert

[Nathan]

Dem, I dont think you know exactly what he's talking about...INSIDE the collector the hole going to the feed for the wastegate isn't cut out as large as the inner diameter of the piping of the wastegate feed, thats what I used the dremel on. Also, one good thing for me is that the wastegate doesn't need to flow as much air at higher boost levels such as the ones I will be running. Hence, it probably wont creep on me at 15psi just because it doesn't need to flow as much. I'm also hoping that my little 20 minute porting job clears up any boost creep anyway.

ah, i see. that's definitely something that should have been addressed. i still don't like the idea of having that feed. even ported, it just seems like it could cause problems with low boost. other than that, it is a very nice manifold.

i doubt you'll have any issues at 15psi . keep us updated.

[Nathan]

Yeah, the ONLY thing I worry about is while I'm breaking the engine in and before I get to go to the dyno to see how the A/F's are. I don't want to boost more than 7psi during that time really Oh well, soon enough we'll find out how mine works. Right now I jsut can NOT get the oil pressure sender out of the thingy, I'm about to start in on it with a chisel or something :firedevil

[Structure240sx]

just shift at 3k and dont floor it going to 3k. doing this u wont be boostiong much if any. i did this after swapping in my new engine and 5spd swap to break in my clutch

[Nathan]

True true, at least I dont have to break in the clutch...(puck) It'll still see SOME revs over 4k while I get used to driving a stick again, it's been a LONG time and I never have done it a lot.

[Structure240sx]

u dont have to break in a pucked clutch? i have a spec stage 3 with 6 pucks and they strongly recommend breaking it in. but dont worry about it this thread is getting off topic now

[j-z]

its about if its sprung or unsprung. so if they recommend to break it in then break it in. and i have seen other STAINLESS manis out there that look way better than that for about the same price. i would say in reality that mani is worth $350.

[BoostFab]

whcih turbo are you running?

[Nathan]

I would say in reality that mani is worth $350.

Awesome, then can you start making some and sell them for that? You'd get pretty much the entire 240 exhaust mani market to yourself with that, at that price...also, care to share about similar stainless mani's at that price? I've NEVER seen one and really would like too. Oh, and Structure...I dunno why there's a difference in spec and ACT's recommendations, but I KNOW the ACT has a very simple break in procedure thats something like "slip it at 3krpms for 20 seconds, then your done" or similar. I have the literature at home on it, I'll check later. Oh, and it is unsprung.
