LS1 Mods

[hj308]

I know this is off topic to Sandmans but I have recently purchased a 2004 CV8-R Monaro and interested in maybe exhaust, cold air intake and tune, anyone on here own/owned a V8 Commy , Monaro etc and made these types of mods or any others that they can reccommend etc. Was given this link by a friend http://www.bobromano.com.au/LS1-powe...it-review.html, I know there are plenty out there offering similar spoke with a place at Port Hacking that does turbos and V8 tunes and his price was around $2500. Have also read about changing diff ratio, curious about the ripshifts as well. In two minds as to doing anything care is one of only 320 build and prob less than half were manual so want to keep pretty much original or if I do make mods nothing too radical and something that can be easily reversed if need be.

i had a auto VZ Ss ute with extractors, exhaust, k&n filter and tuned. Was 333rwhp (from memory?) Wasnt loud and you it looked very orig under the hood.

They put the tune through the power mode button, or some crap like that. You could tramp it with no brake and the thing just lit up. Would shift into second and try and turn itself around 180 degrees! heaps of fun when you wanted it but still very tame as a daily. One of the better cars ive had i think

I had my VZ Cross8 done. I dynoed it before and after. All I did was get a 3.5" single system from the manifolds back with high flow cats (about $1500) and a tune ($600). It was tuned for E10 or 95, didn't want to have to buy 98.

Steve at Oztrack (in the foot of the blue mountains) tuned it for me. It wasn't dyno tuned, just tuned to a basic tune and then took it for a run. A bloke I worked with had the same thing done but he got cold air and a cam fitted and it went even better.

Attached is the before and after dyno runs. Don't take huge notice of the actual figures, remember this is awkW. The final awkW is pretty much equivalent to around 275-290 rwkW on a rear wheel drive VZ auto with exhaust and tune. Look at the gain. The car picked up 2-3mpg too. And look at how flat the torque curve ended up. Car went from a slow, thirsty thing into a real quick beast for a 2 tonne vehicle. It chirped from 1-2 on all wheels and was really good on fuel after the tune especially highway.

I have a HSV GTO coupe. V2. Manual. I have recently spent 13k on the engine. (lots of labour done by myself). Im pushing 350kw at the wheels....

Before I did any engine work I was 320 at the wheels. With a raptor supercharger. The raptor blower kits are about 6500. and are a bolt on kit.

Depending how far you want to go..... I had to remove the blower as we built the engine way too big for it. But have my eye on another bigger blower! Just got to sell my VN SS to fun it haha.

Best place to start. Is a exhaust. cold air and a tune. Maybe a cam.

One piece of advice. Decide what way you want to go. otherwise you will redo things over and over again as things get too small that you have already replaced. eg exhaust. Also keep in mind the more power your pushing the more things you need to upgrade. BRAKES!!! clutch, diff etc etc. =)

Sounds like a real beast your building there Jason, had contemplated a Supercharger but dont think I will be going down that path, spoke with Port Hacking Automotive today tune, opr and full stainless exhaust with headers about 4-4500. Love the GTO coupes as well , yeah maybe upgrade the diff ratio and shifter but will get the wheels fixed or replaced first (gutter rash) and then probably get Van on road first, wouldnt mine seeing some pics if you have some,

Give Steve a call at Oztrack and see what he can do it for. Worst case it is a comparison. 02 91193895

Get have my four wheels machined and repainted in factory colour (2pak) for $800 or I can get a brand new set of genuine ones for $1100 and I know they are now becoming harder to find new.

Are you sure they are genuine CV8-R for $1100? There are repros around for that price, but when I priced genuines they were twice that! Is yours a V2II or V2III CV8-R? I almost bought a V2III new. They were desperate to sell it as VZ's were on sale. They got down to low $40k's, but I really wanted a plain V2 CV8. I could have even had a GTO cheaper than the V2 but they aren't Monaro so I wouldn't tocuh it! Plus I didn't like the body kit on them, sort of ruins the CV8's clean lines.

Those 19" V2 CV8-R rims are expensive. I took the originals off my V2 and fitted V2 seriesII/III rims as the V2 rims are HSV items and the seriesII/III are a lot cheaper and easier to get. I picked up another two V2 rims from ozbox, so I can clean up the best 4 and put them back on now the mrs has her RX350. I now have 12 x V2 seriesII/III rims and not 4 x good ones between them hence the need to clean up some V2 rims.

Yeh its a little crazy... 350rwkw un supercharged. Basically 1st and 2nd is usless.

Its a 6.4L LS1.
All top line parts. so its unbreakable. Also have a $2000 button clutch. genuine true trac diff. Heaps of money spent haha...... I have the go fast bug and its slowing down all old holden projects.

It looks 100% stock from the outside. and even inside is still as factory.

Im about to take it into get retuned. Just fitted some 1.7/8" into 3.5" extractors (pacemaker) and also a full twin difilippo 3" twin system. It should be able to breath now! haha!

Would love to blow it again. (its built for it with low compression) the fuel usage on the highway was under 8L per 100!

Will post up a pic or two once I get it on the road again. after the exhaust is done.



Wheels.... Yeh my GTO wheels are the same. need redoing. same I can get new. But wow not cheap! around $3000!!


the tune/exhaust you have been quoted on. Sounds ok. I wouldnt say its cheap. but its not expencive as long as its a decent exhaust system and not a cheapie.

[hj308]

The guy I spoke with assured me they were genuine when I put the question to him, their is also a guy on ebbay selling them for about $1580 , mine is a V2 III CV8-R Pulse Red, the wheels are actually 18's not 19's. Wasnt aware the HSV Coupes arent badged as Monaros, dont mind some of them with the body kits like the look of the rear end of them, I imagine one day they could be sought after maybe in another 20 years not sure what they were new but still pulling good money from what I have seen, went with a CV8-R as I like the idea of it being limited and low build numbers.
