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?

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.

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.

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.

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.

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.

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???

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.

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.

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.

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.

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.
