Gang...

Looking at getting a G35c 6MT around the end of this year. Probably won't be an '05 as I prefer someone else to eat the "drive off" depreciation. Is there anything to really look out for when shopping?

Thanks..

There isn't really anything that you need to look out for that I can think of. There haven't been any major problem areas and there have been no recalls.

I think you'd be really happy with G35. What are your plans for the Maxima?

The Max will stay my work car. I'm getting married later this year and I told my fiance I wanted to trade her car in for a G35c. She has no problems with that since it's a sports coupe

Check for a rough idle when fully warmed up.

The G35C shares this issue with the 350Z.usually traced down to grounds or coilpack, not nearly all cars have the issue though only a fraction .

Infiniti dealers genereally diagnose and fix, when custemer notices and complains ,but thats about it.

Otherwise trouble free car.

Thanks Fred...

Now I'm researching TT vs. SC so I can determine price vs. performance.

check our 350Z forum for that, much discussion, as the cars are nearly identical.http://nicoclub.com/zeroforum?id=168

IMO TT is too dangerous for VQ35de in our carswith stock internals as so much torque is made down low.Centrifugal SC's seem to be the safest solution yet offer hgood power and low installation cost.

Vortec : Good complete package, kinda maxed out as a set-up but not so much $$ not so hard to install and tuned out of the box with fuel anmd timing solutions includedProCharger: Hardware seems better quality not maxed out at "stock" boost, but need a seperate timing solution purchaeed and tuned which exaserbates the price differential to the VortecHKS: Very high qulaity kit, most expensive of the centrifugals SC's hard to install According to one shop take twice the hours of Procharger or Vortec, looks OEM

TT's:

Greddy: Hundreds have been sold, many installers will know <exactly> how to put it in, great performance and not so spendy only about as much as a Procharger with timing solution, install 2-3 times of a procharger/Vortec.Least expensive of the TT kits and yet has a very high upgradability due to large turbos.

Power Entrerprises: Highly regarded and very complete kit w/ good workmanship

APS: Possibly even higher regarded than the PE kit, extremly complete, these are the guys that found the, now suspected, source of early engine demise in some TT's, in their own research before they released their kit.

Its a unshielded CAS wire which may result in timing scatter, absolutely deadly for the VQ.They include a fix in their kit ( most anyone can shield the wire for the other kits as well, but it just shows how well reserahced this kit is)

JWT TT kit: Very new know little about it, likely a very good kit

The weakest link in the motor is the connecting rods, correct, and the track edition has been updated with stronger rods (from what I have heard). If this is true, does the G35c 6mt have the upgraded rods or the weaker ones?

1) true connecting rods and connecting rod bolts2)This is not all that clear yet, a check with Nissan North America, only talks about upgraded valves, springs.At some point I had a source, said teh rods might be a bit upograded too, but I cant find it again, even a little thicker would help and as the rods experince more tensile stress at higher rpm it would make sense w/ this rpm raises engine3) The G35C 6 mt with the 298 hp rating will have the same engine internals as the 350Z Track/Anniv. the other cars in the model range will still have the other internals

A number og VQ35de's have blown with even perfect tune and moderate boost, but <only> with Twin Turbo set-ups so far. Makes you wonder if it was overboost ( not possible with SC, hence SC blowing engines is very rare nowadays).

Also I know of no SC ,that had a good tune that sustained damage, yet early proChargers installed w/o a timing solutuion sometimes blew engines.

more folks now feel it was not just tune, with the TT's, but timing scatter due to an unshielded CAS wire.

My ProCharger Installer (RTC of Lexington) will shield it for me when my ATI ProCharger goes in.

(Brackets on G35C for ProCharger are different than 350Z and if my car was a G35, I might not go ProCharger, if that is still so, as I been told they boost thru the airfilter on G35 but not on 350Z.)

In any case my car is one of those with the uneven idle (miss) so I need to get that fixed under warranty beofre I can put the stresses of 400+ hp on it and btw lose said warranty.

Any comments on the Stillen SC? They claim the Stage III at 410 flywheel HP or the Stage II (with 3/36 warranty) to 384....

What about SSR? They are claiming "up to around 650hp" on the Z setup.

Guess I should follow along in the Z forums, huh?

1) reliable but also one of the lower power produceers. you need new hood too, to accomodate, its a roots type so more heat, which is why less boost used = less power.Stage II gets expesnive,m 384 crank hp is a lot f less than the Vortec or Procharger which both make about 400-410 vcrank hp and approx 340-360 whp.A valid choice still...

2)I know nothing about the SSR I dont know anyone that has it one and how much the cost/perf reliability #'s are, the up to 650 hp claim is meaningless as by then you would have to upgrade internals anyway (=many many $$)

Thanks for the info...

SSR has made turbo kits for the Altima 3.5 and is finishing up a kit for the VQ35 Maxima as well. I believe they are looking at 10-12lbs boost.

Here's the Z kit: http://ssr-engineering.com/pro...o.php

BTW, a non-SSR "home grown" kit running 6psi boost dyno'd at 347.07 HP, 372.37 TQ. The owner has run it up to 12psi with no problems so far. Dyno is here: http://total-x.net/images/dyno3.jpg

Post by **PalmerWMD** » Wed Feb 23, 2005 4:27 pm

A couple single turbo kuts exist as well, the Turbonetics and there is also an APS coming out.

Not all are install ready for G35 yet the Turbonetics is about 5300 installed at a local shop.

APS single turbo kit about 6k uninstalled. PE is also working on a single Turbo kit. I think the next ST kit to go to G35 from 350Z is probably the Turbonetics.

Fred..

PS: Those are good numbers from SSR, but I dont belive 10-12 lbs are safe on stock internals on a VQ35

Post by **audtatious** » Wed Feb 23, 2005 4:43 pm

Never can tell about a VQ. Look what Hal has done to his pool 'lil Maxima . The dyno was supposedly done at 6psi. He has added SAFC and e-manage from what I can tell and running mostly at 10psi with some runs upped to 12psi. No dyno on that config yet...

I have noted that a lot of TT cars go to single turbo setups for power (like the Supra boyz). Is there any particular reason to utilize a TT setup vs the single? I am assuming the TT setup utilizes smaller turbo's that produce boost quicker than a single "big" turbo setup? Of course, a little shot in the azz with nitrous would solve some of the "slow spool" issues....

1) hal was running a VQ30 an engine not as aggressively optimized for stock performance and possesing of shorter rods which equlas extra strenght for above stock power levels.2) ST = slower spool BUT on a 3.5 Liter thats less of an issue, you can also adjust the trbo, so it spools a bit quicker, between the relatively large size (for FI) and good heads of a VQ35, you dont need a lot of boost to get real fast.

Yes TT's spool up a lot quicker, which is exactly what the Rods dont like.

Even so it becomes clear that the unshieled wire was the main culprit then maybe we can go back to the old days of 8 months ago when we hadnt really seena lot of FI failures on Z's at all and we all assumed 400-500 would be ok on stock regardless.

In any case there is a 500+ whp 350Z running with TT ( and shielded CAS wire) we'll see how long it lasts, it wqas built by a shop in Chicago that wants to test the limits a bit and already has a reserve engine ready.

So, if the issue was mainly due to the TT setup along with the shielding issue, would that make the larger single-turbo setup more safe? Since I've heard the current setup goes so fast through the first two gears, then a little less off the line with more midrange-highrange boost could make the car quicker after launch, correct?

Still trying to "learn". I appreciate the time you're taking

Yes there is a sense among some that a ST is safer thaqn a TT for the same reason a centrifugal SC would be safer in some folks opnions.

I kinda like the idea of a ST, but its only been a couple months sicne the first ST was installed on a customers 350Z ( technetics) not until 3 months delay due to ECU issues was it able to run well.As the new ECUs are still ebing explored.

I doubt the 05 G35C ECUs have been cracked yet.

However the SC's are well proven not overly expensive and harder to screw up in an install.

Also overboost conditions just wont hapen with them, which has been fingered in at least one case as a possible contributing factor in engine breaking.

So in summary:-CAS wire-Detonation due to poor tune or lack thereof-overboost

have been fingered as causes of breaking engines with FI on VQ35de.

SC elimitates #3 altogether, CAS wire, any shop can do that for you, as long as they know ( and by now many of them do, even tho its a pretty new thing)

All thats left is tuning then ( and being humble about your power goals dont shoot for 500 whp w/o built internals)

I doubt I will go for a '05 or '06 model. Prefer used and "depreciated" as I am tired of having to wait years for my value to catch up with payoff

I will definately be keeping a watch on progress from now on. I probably won't get a G until Oct/Nov of this year anyway. Too much going on with planning a Sept wedding....

Post by **PalmerWMD** » Wed Feb 23, 2005 5:46 pm

Mark in Louisville/lexingotn is looking to sell his 04.5 G35C.

Also there is a very nice 350Z Track on the Nissan FS forum right now w/ pics..

Thanks for the link!

Gotta wait on getting the G. Going to trade in the "wifes" Cougar on it, so I have to wait until its "official".
