First, you have some pretty big balls coming in here talking like this newb...

Secondly, the 6th Gen Accord is a different engine than the CLS. It's a J series, but a different engine. It runs at a 9.4:1 compression ratio vs the CLS 10.5:1, which has a BIG factor in the amount of boost that the car can take.

Thirdly, we have a # of people here who have tried running higher boost (5+) with the CLS and have encountered pinging.

I see Modaddict has 8+ PSI which is excellent. How much WHP are you producing now?

goat

they are both J series motors. when we talk about the Z and FI you always bring up 5th and 6th gen maxima's as proof the the VQ's prowless, yet I can't use the accord huh? I wonder if women are allowed to vote in your neck of the woods.

ModAddict

7.5+, not 8+ here

ATI engine management? please?????

goat

ok, ok, strap on your boost on your mighty V6, already! were're just trying to help you son. But apparently you are itching to join the list. :shakehd:

cusdaddy

My Z is a lease, so no FI application is going anywhere near my engine. It produces plenty of HP for me. I just wanted to stand up for the VQ, as ATI is giving it a bad name.

goat

you know ATI has been in the buisness for many years, and have enjoyed countless number of sucess stories on the domestic side. they are just trying to throw some surpport to the import crowd. Seems they are running into a lot of problems with the high strong V6 imports, and durability. Unfortunately, don't expect companies to make kits for you guys, if all you give them is a dick-in-the-eye on your boards.

ModAddict

Don't blame ATI until you can tell me what they supply for engine management whith this kit. If they don't supply anything and leave it up to the installer, don't blame ATI, blame it on the installer/tuner no matter how good/experienced they are.

zeroday

the kit comes with a cheap fmu (uses plastic sliders) and no timing control. for more info:

im going to bed.

zeroday

there's an absolute assload of companies developing FI kits for the Z. we have ZERO concern about driving them away. read up SON you might learn something:

ModAddict

Me too.

I don't really want to read thru all that. I don't really care that much about it. I'm sure there's enough knowledge over there to straighten things out. If people are pushing the kit beyond it's intended limit, it's their own fault, and they should own up to it. If ATI is selling it saying you can run it over 8psi with only an FMU, then they are pushing it beyond a safe level, imo.

I am pushing my CT S/C kit further than CT intended, and will never think of blaming CT, or Acura, if my engine gives up. My TL-S is pushing 7.5+ psi, when most CL-s 6MT are only 6 psi, and no one is really sure why. Personally I think I may be the only 5AT on the high boost pulley, and I think the 5AT does not reach the higher revs as easy, allowing the blower to hold a higher rpm slightly longer than the 6-speeders. I will feal alot better with a cooller intake charge, (intercooler) and a little less timing advance, (e-manage).

BTW, from what I understand,Comptech blew their engine before they found the limit for their kit on 91 octane.

Zapata

hmmm yea but this is established fact....you aren't saying anything that isn't already known?? SO what's your point?


Z owners on this board need to check themselves a little. This is an acura board. Be prepared for name calling, ribbing and harrasement....people sound like sports fans who go on the road and visit their rivals stadium for a game and then complain about the treatement

Zapata

iz ok man All in good fun Stupid for ati to release a kit that has an ass design. Sux for them but as an owner you have to realize that FI w/o fuel management is asking for trouble......

cusdaddy

I know it's a fact and nothing new... As I said before, it was in reference to darrinb's Acura > Nissan comment. I was just giving it back to him when he responded to your original statement.

It was merely a rag, and not meant to be taken seriously

pimpscls

damn

sidemarker

well both Z and cl-s have had tranny problems.

i think every car has tranny problems!!!!

sidemarker

tapwr3000

why can't people just get along

Habiib

I've found something to be odd. It does seem that all of the blown engine stories that I've read are ATI's. I didn't see one where it was a Stillen SC kit. It just doesn't make sense. It's not like the VQ wasn't designed to be FI. In japan a few models have come with the TC VQ, so it can be done.

cusdaddy

Every car on the road will have a small % of tranny problems, but the Acura is to a much much greater degree. Not that I want to start a debate, but it's a known fact that the tranny is the CL's weak link. The Z had a few issues with the manual tranny on a few very early build models, but the problem has been addressed.

I just want to let it be known that I feel each car has it's problems, and the Z has it's share of problems too, so I'm not saying the Z is a better car by any stretch.

zeroday

I noticed the same thing Habiib.

zeroday

check yourself biatch.

Go to www.my350z.com and do a search under my username. you won't find any acura bashing whatsoever. The whole 'rival team' idea is really really :ghey: . We're talking car companies here. This Acura>everyone gheyness goes on here ALOT and I think it either stems fro immaturity or jealousy.

IMHFO.

Then I'll chime in personally here-

Bad trannys:

MY 99 Accord after 2 years - 1

MY 2k2 Maxima after 2 years - 0


For the rest: DONT even go there with the J series > VQ35 b-llsh-t!! It's a weak ass argument. Both are good engines and both have a relatively high CR which is not conducive with moderate-high boost.

Hey Goat, there are major differences between the J30A1 and J32A2, as indicated by zeroday. The VQ35DE in both the 5G and 6G Maximas are identical (it's the intake manifold and exhaust which result in the add'l 10hp/9lb-ft in the 6G over the 5G).

All that said, you need to tune extremely carefully (not to mention competently) when adding FI to ANY 9.5:1+ CR application.

Habiib, which VQ35DE models come with stock FI in Japan???

zeroday

hmm...yeah i just noticed that comment too...i think he's mistaken on that one.

blubyu2k2

not sure at 7psi the 350z's are hitting 365-385whp with the ATI unit. So its safe to assume at 5-6psi it would push out about 340-350whp

blubyu2k2

I find this thread a bit humorous....

Habiib

Nope not mistaken

Cedric with VQ30DET

It is also an engine choice on the Nissan CIMA (aka Infiniti Q45). Maybe I should have specified that it is the 3L VQ and not the 3.5L.

scalbert

OK, in about a month we will.

But we are running 6 - 7 PSI non-intercooled boost right now which has nearly the same detonation threshold as 8 - 9 PSI intercooled.

Their problem is non related to the engine IMO.

scalbert

And now we have a good idea of the reason and have corrected it. Knowledge and testing is our friend.

However, I was suprised at the durability of the J32A2 when faced with problems. I was running 6+ PSI for a short period before I found my FPR had gone south on me with no fuel enrichment and there was no resulting engine failure or damage.

BoostedM3

Okay, before I get started I just want to say I'm not saying all 350Z with FI are going to blow, but this is just more proof that even with tuning FI on the Z can be risky.

I was just looking through my350z.com and someone blew another 350Z motor, but with the Greddy Turbo kit this time(username=TheFuture). Ran it out of the box with profec boost control, 5.5-7psi, tuned, and blew it in 5 days! He doesnt know exactly what happened, but he thinks the rods broke. He's stripping the engine and going to find out soon.

With the Greddy TT at 5.5psi, he was putting out 345hp/331tq & at 7psi 375hp/350 w/ no cats & borla dual exhaust. Too bad his motor started detonating.

failing to see how i got owned. you'd be an idiot not to be nervous adding FI to an engine on a new car that wasn't designed for it.

zeroday

that really sucks...i'll let others be guinea pigs till they get this figured out.

synth19

You didnt start shit because you are a moron. This shit is old...even if you are joking. simply :ghey:

scalbert

Look at me, I'm an idiot...

zeroday

there are exceptions to every rule

ModAddict

zeroday

we agree on something!


j/k

zeroday

i am starting to think it's a really good idea to replace rods/pistons if you go FI with the Vq35...if anything just to be safe...expensive though. if this greddy tt failure was due to broken rods, then it will be obvious the VQ needs to be bolstered internally for FI. If it's pistons melting...it could still be bad tuning. Time will tell.

CLpower

from what I understand the fuel system in the new VQ design may not be up to the FI task

F23A4

I agree.
