G6Et First Tune

Recommended Posts

Hi Everyone

Im new to the forum and just thought I would share results of the first round mods for my G6. I bought the 08 G6ET just over a month ago with 90000km as a nice everyday drive car.

My first mods were to fit a PWR stepped core, I then made my own 2.5" alloy piping to replace that plastic mess. I also fitted a K7N RE0870 air filter and made a custom air box. I looked at the intake muffler but didnt think it posed much of a restriction.

First impression after this work was it made quite a big difference to low down torque and throttle response. I didnt give it too much though as I hadnt put the wide band on to check AFR's. I did note however that my fuel economy improved by around 2.5L per 100km, cold air works wonders.

I then stole some FG F6 injecteors out of my EB turbo I was using until the EB was run in. I fitted a 100cell 5" barrel cat and downloaded the base tune I got from Simon at Morpowa. Couldnt belive how much stronger it felt with minimal throttle. Drove it out to Simon and first run it pulled 300.2rwkw, not bad I though with a fairly fat AFR. Trimmed some fuel out, a bit more timing and we got a best of 323rwkw and around 890nm (corrected) by 2900rpm. Boost was peaking at 17psi for a second but then dropping to 14/15. Possibly due to having a standard dump and soggy accuator?

Cant belive how strong the FG pulls with minimal mods. It has no problems getting skatey 1st 2nd 3rd with traction on at half throttle? What the??!! Traction off is a waste of time. My last car was a VY SS I turboed, it made just shy of 400rwkw, the G6 is such a nicer stronger streeter.

Anyway a big thanks to everyone on the forum for all the valuable information you have donated :)

Kind regards Jon

Time for some better tyres to make use of the increase! The torque feeling is something else hey, would be snappier on the smaller FG turbo too!

Thanks guys, yep love that 35/76. Will get my tailshaft done and take it to the next street meet with some slicks and see what we get. I have a 35/82 in the shed I am going to steal the exhaust housing and port the gate/ fit bigger flapper so I can run a 4" dump. The waste gate solenoid is at 100% duty cycle and we cant get any more boost, hopefully the 4" dump will help with this. Think I might go the GTX 35/76 as I looooove how quick the smaller comp spools. My EB has a rather large snail on it (master power R656) and it lags lots, although very fun once boost comes on LOL

Will try n post some pics tonoght of the pipework with bar off :)

Kind regards Jon

Hi Guys, a bit late I know, heres s pic of the bar off with the pipes I made up. Also a small pic of my turbo EB :)

I have noticed though that the power delivery of the G6 has slowly started to taper off for some reason. I thought I may have been getting used to the power but its starting to struggle letting the tyres go in 2nd, where as before it would fry them with minimal throttle. I will have to find some time to do some data logging of the boost, I thinks its getting a bit soggy. The OEM 35/76 is getting a bit more than avarage axial play and is starting to make some funky bearing noises. I have been giving it a lot of thought and I think I will go down the GTX35/82 path now instead of the GTX35/76.

Is anyone running the GTX35/76? Thoughts?

I will start making my own battery relocation and getting it all ready. Thinking also of some high flowed Nizpro injectors, anyone using them? Otherwise I will go for some ID1000.

Hopefully have it all sorted with the new snail in a couple of months. I have to get some more work done on the house first to appease the minister of war and finance LOL

Take care everone

Kind regards Jon

Thanks guys, my thoughts on the high flow injectors aswell. It looks like ID1000 units then. I have had problems in the past with getting a good idle with 80lb Siemens.

Will def go the GTX35/82 and full exhaust. Think I will fab my own 3.5" system. I have seen well over 550rwkw made through a single 3.5" before so it should be fine.

Yes the Eb xr6 turbo is a nice car, too scared to drive it these days as it seems to attract a lot of attention, especially with its cam. Sounds a bit grumpy. It makes the G6 seem a bit underpowerd LOL. My mrs is wanting me to sell it, as it just sits there. Was going to do a powerglide for it. Currently runs expendable T5 boxes. Heres a pic of the R656 and merged turbo manifold I made on a dummy AU engine, I was running a 44mm Tial gate but had over boost issues. Now running a 60mm Turbosmart power gate and revised outlet with Eboost street. I should pull it all off a put it on the G6 LOL

Thanks again for your advice men

Kind regards Jon

Hi Guys

Thankyou for all the welcomes :) Its nice to see there are still some freindly peeps out there.

Yep, been a boily specialising in TIG welding for about 25 years. Been playing around with cars for around the same time too making bits for em like turbo manifolds, custom pipes etc. Bit of a hobby/career.

Simon from Morpowa is a top bloke and I trust him 100% with tuning. Will be calling him again this week to get some more tuning done soon.

Hope everyone has a nice evening :)

Kind regards Jon

Just in case your intrested the GTX 76 is a great turbo and a couple have it now

Everyone opts for 82 but if u like that small turbo rush stay with the 76

Simons been around for a wile and tunes a nice [TOXIC F6] that wayne owns, best part about simon is that the king dingaling martin donnon taught him

Wow, Simon learnt from the old street tuna LMAO. I remember Martin from the old Fueltronics days. Yes was a bit perplexed about who to tune it in SA, I deal with Simon a fair bit at work and he seems to be getting some good results. I think tuning is one of those things, you go for a drive in your mates car who MR X tuned and it rattles its head off, then you hear storys about someone else having drama's with another tuner. From passed experiances with other tuners I was very happy with the amount of care and detail Simon put in. I would love to have a go myself someday but I would be worried sick I might stuff up a VE table or timing somehow LOL. I will stick to welding :)

Hmmmm, got me wondering about the GTX35/76 now. The stock 35/76 has some nice punch from low but seems to lack a bit at top. I spoke with old mate Bill from ATS about the GTX 76 and he reckons it flows as much as the standard 82? I might give Bruce a call apparantly he has done a few? I just know I will end up wanting more, always happens LOL

Thanks for you advice bud :)

Kind regards Jon

Road Salmon!! just fell on the floor in laughter!! Yep those were the days doing chips on the Camiras, Delco crazy!! haha. Wonder what ever happened with Julian Edgar aswell? I remember he did a test injecting oxygen from an oxy cylinder into a Camira on the Dyno LMAO! Thanks bud you just made my night that bit brighter. Damn Im feeling real old now :) I am half tempted to fit the R656 from my EB, its about the same as a GTX4094 with billet comp wheel etc. Heres a pic of the setup I done on my mates with the same snail, I reckon Bruce ended up tuning that one. I just built his manifold, fitted the gate and turbo, it was a bit of a piggy engine bay. Have a good one bud, thanks again for the laughs. Will keep you posted

Kind regards Jon

Hi everyone

My appologies for not being online and updating the build. I had some bad luck a month or so back on the way into work when a roo jumped in front of my G6. Only just got it back from the crash repairer last week. Needed new bonnet, left gaurd, headlight etc, etc. Positive outcome was a XR8 bonnet was fitted and I bought some 20" Dark Argent reps with 9.5" 275 rears. Hooks up much better now :)

So now onto the fun stuff, I will post pics as I go. Will start building the exhaust first, then fab a batt reloction tray and R/H cold air box in readyness for the GTX.

here are a couple of pics of her now

Take care all

Kind regards Jon

Mate sometimes out of bit of bad luck comes something better. Your G6 looks great with the bonnet!

Im getting all these flashbacks aswell with the likes of fueltronics and julian edgar being mentioned. Back in early VL turbo days he was one of the 1st guys mucking around with them.. I had one so youd try and get as much info as you could.

He was definitely left field in his thoughts.. some things worked..others didnt..

Im also curious about using the GTX76.....

Thanks Jimmixr, I am pretty happy with the bonnet and wheels. Changed the whole look of the car, even the Mrs likes it now which is amazing, as its pretty rare that she like anything at all!! LOL When I got it back from the crashies with the bonnet I thought I better get some wheels cause it looked rather limp with the 18" factory alloys!! yep its been awhile since I was reading about playing with different early EFI systems. Starting to feel real old at 40 now :( shame cause I still feel 18 inside, its just the body doesnt anymore! haha. Things have changed so much from my early days of playing with Clevos. I am waiting to hear back from someone who is getting a 76GTX tuned in the next couple of weeks. Also a mate in NZ who has come up with a bolt on upgrade using a billet 92mm comp wheel which should be intresting. Might give him a call next week. I will see what the results are then make my descision. In the mean time I have a bit of fab work to get done on the G6, in between the Mrs cracking the whip to get stuff built around the house....damn it! take care kind regards Jon

Im definitely interested to see the results of the 76...

Im so ready to move on the next round of mods but Ive stalled on the turbo. Yeh alot of people say its a no brainer..go the 82.. but after chatting to so many turbo shops/suppliers its only confused me more.

Back to the early day.. My 1st mods to my then year old VL turbo was a new cam from a normally aspirated Nissan skyline GTS and a matched fuel tronic chip.

The skyine cam had more lift with the same overlap.. bit more boost and a gutted cat ..

It was all early sneaky Group E racing tricks..

It was definitely quick for its day...still miss it to be honest..

Hi Jim

I will let you know how this GTX76 goes. Im a bit perplexed about the 76 vs 82 aswell. I will have to have another chat with Bill at ATS about the GTX snails. One thing I am concerned about with the garett is the small diameter turbine shaft, probably why you see so many 35's with the turbine wheel fallen off!! I hope the GTX has a larger shaft, as hanging a 700+hp compressor wheel off the same 35 shaft wouldnt be good? Hopefully the GTX is upgraded?

The VL was and still is a great car. A freind of mine has a real nice Calais with stroked LS engine big cam etc, its a very tough ride. I seem to be only one of a couple of us out of all my mates who went down the turbo route after playing with V8's in the early days. Everyone else is still into the big cube 8's which are tough as with a few of them running 550+ cube engines plus boost.

Im hearing you, I miss my XY 351 fairmont, wish I still had that, it would be worth a pretty penny now!

I should spend my time and money on building a time machine instead!! Hmmmmm, I could go back to a time when my wife was still human! LOL

Kind regards Jon

Just incase your intrested julian writes for zoom and works at autospeed so still kicking around !!
