turbocharging V6 commerdore

[redman]

what do u have to do to turbocharge a VN V6 commerdore

[karl_2ltGC]

alot

would most likely need custom manifolds, new map sensor to handle boost, engine management, a turbo ;) piping....

Lots of custom work...i hope your handy with a welder

[Quick V6]

how much power are you trying to get

[PSI-70Y]

there was a thread about it a while back, some company, (maybe CAPA) has turbo ktis for them, use the search function to look for it

quite expensive though i think and if i remember correctly it was a single turbo running of 1 bank only

Here's (http://board.performanceforums.com/forums/showthread.php?s=&threadid=67116062) the thread PSI-70Y was refering to.

[Rogs]

I believe that the americans also use this engine in some of there cars have a twin turbo version is available. Might be worth looking into.

[AutokaT]

sell it and buy a silvia!...hahahahahahaha...no seriously...just sell it!!

[redman]

in terms of expensive, would cost around the 5 grand make or a bit more

[redman]

i am not to sure how much power i want but i may be around 200kw if it is possible but i msybe just dreamin a bit there but the most i can get for my money

[Quick V6]

this is te quote i ust got for my vs v6
have been told it will run 15lbs of boost and make anywhere from around 350 to 400 rwhp

2 x wrx turbo 2200
mt8 microtech 1195
exhurst manifolds 440
oil and waher lines 575
intercooler 1250
custom inlet maifold 335 (twin. will look mad!!!)
exhurst 1100
copper gaskets 275
pods and plumbing 410
hi flow injectors 640
fuel pump 485
labour 1850
mod plate 66

total $11461

it may not be the cheapest way of doing things but it is the way i want to do things. this kind of set up should run mid to high 11s.(i hope.) this will be getting done in about 6 to seven months and i will keep you all updated.

[redman]

that is rather pricy i only want to spend around 5 to 6 grand

[Quick V6]

you said you want 200 kw
is this at the wheels or motor

[redman]

at the fly wheel for starters, they have a reasonable package at commsport.com.au which looks rather interesting

[Quick V6]

to get around 200 kw at the fly wheel just get a cam and chip package and get the heads worked and rebuilt. i did this and got 185 rwhp and it only cost $2200. you dont need to go to the trouble of getting a turbo for a small gain like that

[pearlvk]

considered v8 conversion

[redman]

umm yeah i was just thinkin for starters cause i wont be able to run much boost till i make the engine a little more turbo compatable otherwise it will just blow up, but i really want around 300kws as the losest in the end

[redman]

v8 converson is rather expensive 2 and it is not very custom

[Quick V6]

ive been through all the same ideas . go with the cam and chip as it means the top end of your motor wil be rebuilt as well which also means you will be able to run up to about 14 pounds of boost when the time comes. makes the v6 sounds sweet to

[redman]

yeah i might look into that how does it go with just the engine work

[Quick V6]

its sounds tuff and can do a 14.2 1/4 mile

where are you from if your near me ill take you from a cruise in it so you can see for yourself

[madza7]

on my VG ute V6 5speed i had hte heads rebuilt (had blown head gaskets) and had a HDT chip/cam package installed. also had extractors + a 2.5" system.

this gave me (on bill lee's dyno) 128kw @ the wheels which equated to 148kw at the fly.

I ran a 1/4 of 15.3 @ 148km/hr.

a friend had his VR V6 dun with big cam, heads, big compression, zaust and the usual remapping etc etc. also had the auto done up and a different set of gears put in.

best he could run was a 15.1 @ 148km.hr

so how u manage a 14.2? and at what terminal???

if u want to run a genuine low 14 then forced induction is hte only way.

seriously though if your after performance dont bother with the v6. there a good, reliable and economical engine with GOBS of bottom end torque and thats it.

after i sold the v6 ive been through 2 v8, which IMHO you'll be a lot happier with. sold the vnss after 6weeks for the rote though :D

just my opinion on my own personal and REAL experiences with hte v6.

[redman]

i live at bridgeman downs which is near chermside, where did ya get all ya work done

[Quick V6]

I got it all done in toowoomba at a place called aero tech.
if you can spare the time it would be worth coming up for a drive and see him, he has really good prices and really knows his stuff.

my mods with him so far are

pacemaker extractors
2.25 zorst
crow comp cam
micro tech computer
heads rebuilt and highly worked.
3.45 diff gears
stage 3 shift kit with modifyed valve body.

so as you can see he can do almost anything you want or need.

dont listed to everyone who keeps saying buy a v8. why not try and be a little different.

if you decide to come up here let me know and ill take you to areo tech to meet pete and see what he can do for you.

disclaimer. 14.2 was measured useing a apexi rev speed meter with g sensor. so it may not be 100% accurate. but that does not give anyone the right to say or implie that i am making things up untill you have been in or know someone thats has been in my car.

[madza7]

quickv6: well even so, but i still reckon my 5speed VNSS which had extractors and a twin 2.5" system would still beat the v6 and sound better.

btw u do realise the delco (stock) ecu is FAR superior to the microshot. $1295 + setting up down hte drain......

[redman]

do u know of any quaility places close to me

[Quick V6]

mazda 7 yes that maybe right. i have no doubt that a good v8 will always sound better. but not all of us can afford to just up and change cars. so we have to do what we can with what we have. sure i could probably been able to buy a decent v8 if i saved the cash i have spent on the v6. Just trying to be a little different.

redman: try redcliff dyno and perfromance. they are a litle rough around the edges but can do what you are after. or if you dont mind going to the gold coast. you cant go past chip torque.
crt perfromance in brendale
pro street perfromance in brendale (just opened but he is a top bloke)
brisbane tuning and turbo supplies. ( if you go for forced induction)
. but if you want a few really good places you need to go to the gold coast or head out here to toowomba. pm me your phone number and next time im in brissy ill come and see you.

[Quick V6]

mazda 7: the delco maybe better. im not sure but im happy with the micro tech. very easy to tune and has dash mounted screen. shift light and warning lights traction control and a lot more user friendly when it comes to turbo time.

[TurboVS]

You will get a lot more then 200kw at the fly. I run only 8psi at the moment and make a lot more power then that with a standard bottom end. But there is a lot of headwork and cam and valve stuff doen to mine. The cost is very high, but it is different. I have a VS though, the VN engine won't handle the power as well, but it should still give you a fairly good gain. Put it this way I don't think you'll have much change out of 15k if you do it properly, and by that I mean big front mount, big injectors, custom plumbing and big ball bearing turbo. email me if you want more info - damen.cole@defence.gov.au

how much will the stock bottom end / rods / pistons handle in these engines under boost? much over the 200kw mark?

also is there any difference in strength with the VN v6's and the newer VR -> v6's? (I know they are the same engine... just wondering if holden made anything stronger)
asking for a friend who is interested in tht same thing :)

Umm actually, the motor's are actually quite different. the vn, compared to the vs motor, has different pistons pin heights, and conrods lengths..
The standard rods and crank, have been proven upto about 400hp.. with aftermarket pistons that is..

A little hint if you wanna go further than that.. get a buick scat crank, and a VN block .... mmmmmmmmmmmmm i can smell the HP already.. aftermarket rods, pistons, big t66 turbo ...... :)
