Hi Jas, i think their v6 might've been in a Torana or something so it was probably quicker than the old commo. I'm still toying with mine, i'd like to go turbo if i can find a cheap kit, i'll just drop the comp with some thicker gaskets and try around 15-16lb boost. Otherwise i have a 240 @ 50...

Diggin up an old thread, do the cometic c5691 fit straight up without an extra hole drilling?

Hey Jas, still around mate? I'm struggling with solid roller lifters for this thing, i don't want to go down the bronze bush path or $800+ lifter sets, any ideas? I have found Morel make a set Part No 5553 but i can't find anyone to ship them here. What are all the speedway guys using?

Yeah definitely mate, the guy i bought the camshaft off builds and races them for speedway, they are well developed and have the ecotechs pushing 330rwhp with a standard throttle body! I was trying to find an off the shelf 3.9"+ piston to use but without also using a stroker crank just can't...

Not 100% on lifters yet Jas as its more of an interim engine i can't afford to buy brand new tie bar solid lifters, was thinking maybe convert a set of spare hyd lifters i have. Yeah exactly mate, it's not hard or expensive, most of the money is in the heads but otherwise it's a pretty...

Hey Jas, My turbo motor may take a while to come together, i just happen to come across a nice v6 solid cam on gumtree, i'm thinking i'll slot that in with some thinner headgaskets (11:1) and see what she'll do. It's a custom grind 240/246 @ 50, 600lift ( 1.65 rockers) 108lsa. Adv durations are...

Hey Jas, check this one out i spotted on fb, 209rwkw through an auto, still 3.8, not sure if it'll see the track though, it's a burnout pig. https://www.facebook.com/The-SKID-PIG-461283594045198/?hc_ref=SEARCH https://www.facebook.com/Proportengineering/?ref=br_rs

Hey Jas, i've still got the VR sitting in the shed too, has been off the road about 2years, lost interest. However a new job has me thinking of ditching the n/a setup and going turbo, just sorting out a piston/rod combo now, will aim for about 450rwhp on 15-18psi, and be kind to the poor old T5

I have a 196rwkw, std stroke vr v6. It is nothing too crazy, it runs stock crank and rods, acl pistons. comp is 10.7:1. heads are where the $$$ go with lots of porting, oversize valves etc etc. still runs standard intake but port matched, 70mm tb. cam is a wade 1365a (228 @ 50, 520' lift) has a...

Yeha it's fine for now, on nos might be different though, nos makes lotsa torque. You've put my mind at ease a little with the box though delco lol it has been rebuilt. I just dont wanna be stuck at willowbank trying to get a tow home and be 'that guy' that dumped oil and ####ed everyones night lol

I know they are capable diffs when built but mine is dead stock apart from an LSD which i suspect is on the way out. Changed oil and additive the other day, no serious contamination yet lol. Delco has twisted countless axles and broken diff's and T5's with only a boosted stock internal v6. T5...

2 days ago it had flat tops?? [email protected] is huge now is it, no good below 3k??, look at the dyno sheet no lack of low down torque there mate. haha your right the ET's don't reflect it's potential/hp, it's a manual, in full street trim (1400+kg's with me), with 3.45 diff gears clearly not a drag...

I think you'll find they're dish pistons, flat tops dont work in VN-VR V6 unless your chasing 16:1 compression, they have tiny 35-37cc chambers remember. You won't be anywhere near close to PTV, i dont know where you're getting you info but it's all wrong. That cam is a regrind on a stock cam...

Read it again mate, ran 104.8mph with 263rwhp. Ran a bit over 100mph when i had 247rwhp. There are others on here claiming 291rwhp but only runs 103mph. That PTV doesn't sound right man, i had a 230 @ 50/.600 lift in a stroker motor with plenty of clearance, just saying. 212/212 .470 with 11:1...

Just ran 13.19 @ 104.8mph. With bigger burnout it gripped and bogged no matter how hard i launched. Little burnout and maybe slipperier outside lane at willowbank?? bit of wheel spin off the line and no bogging down. That helped et's, but 60ft stayed 1.9 all night. Dyno'd 263rwhp which is backed...

Its 40thou over 10.7:1, wade 1365a cam, o/size valves and good headwork, std manifold and elbow with port work, 70mm tb, 3.45gears. It's begging for 3.9 gearing but i can't justify the expense and revving high on the highway for a few tenths at the strip. Have just converted it to run e85, will...

My VR V6 n/a manual was around 2.3 60ft on shitty street tyres, then fitted 235/60/15 et streets best so far 1.9. Its hard to not bog it down though even with 5000rpm launch definitely takes some finessing. Best et so far 13.4 @ 103mph.

I have just done this to my n/a vr v6 i'm actually setting it up for a sealed catch can and retaining the pcv so its all legal. After reading about pcv systems i discovered the s hose from the manifold to the throttle body is actually to let fresh air into the system it doesn't actually pull air...

Will get some on the weekend after a wash.

Still have a few tricks up my sleeve to push this a little higher.

Ok Steve, How do i get the ball rolling i'm assuming you will require a deposit? Pm me your details. Cheers Dan

just took this mate, doesn't pick up the idle so well only a cheap digi camera but anyway VR V6 250RWHP NA - YouTube

Thanks Steve, Currently debating as to whether i will get these plus the comp cams trunion upgrade or not, it'd be good insurance but the cam is only a 228@50 282adv and with the rockers i want lift would be 547"/563", what are your thoughts? Just want to make sure too, could i get them in a...

That's a nice solid rebuild mate, should last a long time and will be a lovely street engine. 300hp at the engine maybe, it should go close probably not enough cam or headwork tho by comparison i have the Wade 1365a in mine, 10.6:1 comp, ported heads, ported manifold etc etc and makes 255hp atw...

A 236ci is a 40thou over bore like i have in mine

Ok well i have some 8.0" but i've had abit of head/block and rocker mount machining, how much minus the pushrod set? Cheers, Dan

Hi Steve, Sorry for the late reply it's still a Hyd cam (wade 1365a) but i used to run the Comp 875-12 lifters which required only very little preload so i went for adjustables to get it spot on. Now i'm using the 850's which are fine with 30-90thou preload. What length are the pushrods you...

Hi Steve, I have a well built n/a vr v6 making 252rwhp, i'm interested in doing a rocker swap on it. It currently has YT 1.65 platinums (3/8" bolt) but they require the big rocker cover spacers which never stop leaking and i'd like a little more lift. Is it possible to get some 3/8" bolt...

Find a way to post them, i really want them hey, i will more than cover postage costs.

Mate i will take them if you can post them to Brisbane? Obviously happy to pay freight charges.

This is not my car but sounds awesome at idle atleast. It's Vs v6 3.8 with a big solid cam apparently. Holden VS Commodore Cam - YouTube

Do yourself a favor and take them to Peter at Horsepower Engineering at Capalaba. He did the heads on my 250rwhp n/a v6, has done heaps of rnd does speedway v6's. I was in the same boat as you bought some already done heads turns out they weren't so great but with a little work now flow 230cfm...

make sure you get it to the strip mate that will be the real test. as others have said that seems way too high. i have 185rwkw from my n/a 3.8 and it has the best of everything (98RON, 10.7comp, 238@50 cam, oversize valves, 355hp potential heads, etc) , the heads need alot more than a little...

Vn/Vp heads have a 37.4cc chamber standard you might want to re measure or someone has hogged the **** out of them previosuly. Vr heads have a 35cc chamber. With my vp heads shaved approx 20thou and oversize ferrea valves fitted i got them to 35cc.

Looks good mate they respond well to ported heads. On a side note VN/VP heads have a bigger chamber than VR 37.4cc Vs 35cc so you actually lost compression using the VN heads.
