ey guys, do u's think its worth the time and money to stick a rb26 engine into a vt. how much would need to be changed, ive heard some suggestions, i dunno if it'd be worthwhile.

dreamer

yeah agree. stupid. chalk and cheese

In a VT... Some where around the 10,000 - 15,000 $ mark.

wouldnt get it past blue slip anyway - dont think you can put an older motor into a newer car (not sure on release dates of VT and last dates on R34 gtr builds).

Waste of time and money IMHO.

Theoretically you can put an older engine into a new car, but what you need to do is prove the emissions meet the ADR's that the car was built to (as opposed to the engine). If this involves an ADR drive cycle test costing several thousand (whether you pass or fail) then I start to wonder if it's really worth it.

I'd ask the question whether you would get a better result if you threw the money at one of the V8 donks.

yer wat you talkin about i seen plenty of people putting RB30's into R32's and R33's and there an old engine.

for something different y not, dont listen to these guys, if u got the money and want to do it, im sure it can be done for a reasonable price, get some mates who r in the business to help u out

dreaming buddy...........

Just because people are doing it, doesn't mean it's legal.

they just put the block in and retain all the newer emission gear with the head

Yep, and by the letter of the law I don't believe this is technically legal because my understanding is that engine identification is based on the block as opposed to the head. The chances of getting caught are however very slim because it would take someone with intimate knowledge of RB motors to pick the difference between blocks/engine numbers (not your average cop, rego inspector).

There are also times when engine numbers get accidentally machined off and restamped during reconditioning, after which it would be almost impossible to determine where the block originates from without taking it to bits, but I didn't say that.

whats so good about a VT that you would want to throw that sort of money at it.. :confused:

At the end of the day that's personal choice tho, plenty of people throw lots of money at cars that I think are goddamn aweful pieces of ****e

I still reckon it's more pertinent to ask whether a Rb26 is better than a VT motor + $10-15g of mods?

at least put it in a better looking car

i remember seeing a VU ute with a rb26 in it at easternats this year. no offence but it looked bloody awful and looked like more trouble than it was worth.

Do you have the RB26 already? If not then maybe consider the VG30 V6 3ltr twin turbo nissan motor out of the 300ZX?

if its gonna cost around 10 to 15k... just TWIN turbo the vt motor.. not many 3.8L ecotecs with twin turbo..... and itll go twice as hard as what the rb26 will go :):).....thats what ill do anyway

i heard the 300ZX engine isnt very reliable i seen people put an RB20 into a VR commodore so im guessing an RB26DETT would go into a VT

im sure you could legalize a RB30 into a R32 browny i seen a R32 running a cressida engine turbo probley seen it the white Rigoli r32 i think it duz low 9's but yesh i i think with engineers its very legal.

and a VT would look nice with the newer lights and bumpers of the latest commodore and a Monaro Bonnet vent and so on rims you can make them look very nice.

really wouldnt you rather spend abit on a 98 up commo then a 87 commo unless its a calais turbo lol.

RB20 into a VR..gee..nearly half the capacity...

and why would you stick a 300ZX V6 in a VT..gee, thats just crazy..

Best performance for your dollar in a VT i reckon would be a twin turbo, alloytec V6 engine, may need a fresh build to strengthen further,(pistons rods etc) not sure what they can handle.
Or a Gen 3 engine, came out in the late VT's.. get hold of one of them and wack a blower on it....

Personally i am not a fan of the V6, but i couldnt justify going to all of that trouble of sticking an RB engine in a VT when there are plenty of options for power with less headaches..

Yer i thought it was pretty crazy aswell RB20 into a VR and a VG30 i wouldnt do that i think best for a VT would a be a Big EFI V8.....or RB26DET.

twin turbo V6 i guess would be nice but didnt the VT come out V6 ECOTEC superchaged??? if you could get that couldnt you just rid of the charger and wack 2 manifolds and twin turbo setup the block would allready be setup with pistons with low comp ratio...... piping cooler exhausts and a good ecu like a motec or somthin man it should hammer thats what i would do.

VR you can still bolt the VL crossmember straight in.

VT, you can't bolt the VL crossmember in, so it all custom job.

I've always wanted to put a stock 2J motor with a T88 into a VY Calais (Rip out the LS1 dunger). If i had money i would, maybe in the future, once the VY drop in price.

Well, if VG30's are crap then why has the RB26 been dropped out of the GTR for a V6 3ltr twin turbo?
Also a VG30 is ready for turbo's where the ecotec needs lots of work for turbo'ing. Since when is a V6 holden motor more reliable than a nissan engine?
Can someone remind me why we are all here 20 years after the VL was built? Did it have something to do with the motor?

But then I could argue on both sides of the fence as you either have to:
VG30: custom engine mounts; custom fit gearbox, tailshaft; etc.
Ecotec: engine rebuild for turboing;
So I suppose you would spend almost the same money which ever way you go.

yes it had alot to do with the motor and how many vl's on here havnt been rebuilt :)

VG are old hat now.

VQ's are all the rage, you have to wonder though, with all the Japs ripping the VQ's out of the Z's and putting RB26 back in...

didnt they do it for some power and emission restriction, but since then, the laws have changed... could be wrong, i just remember reading it somewhere...

if its gonna cost around 10 to 15k... just TWIN turbo the vt motor.. not many 3.8L ecotecs with twin turbo..... and itll go twice as hard as what the rb26 will go :):).....thats what ill do anyway

seen it done, doesnt go "twice as hard" more like "twice as slow"

with regards to the ecotec

i was always told you can't polish a turd, no matter how hard you try!

im sure you could legalize a RB30 into a R32 browny i seen a R32 running a cressida engine turbo probley seen it the white Rigoli r32 i think it duz low 9's but yesh i i think with engineers its very legal.

I have to preface my reply with the disclaimer that I'm not a signatory so I may very well be wrong.

My interpretation is:

S1 & S2 R31/VL emissions comply with ADR37 2nd Ed. R32 Skyline with ADR37/00 3rd ed. Therefore to put an RB30E or RB30ET into an R32 you would need to prove the emissions are compliant with ADR37/00 which means a drive cycle test. Which means big bucks. You might be able to get away with a S3 R31 engine because that's ADR37/00 territory tho.

RB30DET isn't a factory engine, and therefore there's no proof of compliance with any ADR's, which means you need to prove this with a drive cycle test.

So in both cases it can be a 100% technically legal conversion, it's just not cheap to make it so (S3 R31 engine may be an exception).

However, you are unlikely to get pinged for the twin cam conversion if you go about it the right way, just because it looks so similar to the factory engines.

i understand wat you mean browny but if say just an RB30ET im sure you can make it legal.

i have heard alotta stories and seen 1st hand when 300ZX goes bang i guess it can come down 2 manufacture or tuning i guess u knowes but i have also seen people put SR20's and RB26's back in 300ZX'z

but as i said im sure there was a SUPERCHARGED holden V6 standard its either in the statesman or SS commo im not sure.

im sure they came out standard with it get this engine if ya VT and there goes any building of the engine internally as it would be fine and low compression.
