ls1 conversion

[kniever]

hey all,

just wondering if anyone has done a ls1 conversion into a vn yet or if i could get any info bout doing it

one of the things i wanna know is are the engine and tranny mounts in the same spot and if not how much approx would it be to get it engineered?

[h0Ld3n`VN]

greenfoam saiid it was done he even supplyed a picture.. as i can remember he said you gonna pay up2 8-10G for it.

[skobs]

there was a vp ute on ebay for about $15,000 had an LS1, but apart from the engine it was still a rolling shell, not sure if its still on ebay but yeah bout 10g's

[PaRaDoX]

imo stroke a 304 :P

[Emackulation]

imo stroke a 304 :P

Yeah good idea. I can think of heaps of ways to spend the 8-10g on a 304, better then wasting it on a LS1, unless your doing it to be different...

[Doctor Sodways]

It has been done numerous times, there was a stock looking VN, granny spec, grey bumpers and chasers that was running one with a carby set up for the drags, built by a 17 year old at the time, that was a little while back, was in the street commo mag and stuff, he used the LS1 forum a little bit. There is a guy on LS1 that is building a VS GTS-R replica with an LS1 as a burnout car too

As for the stroker vs. LSx debate, they each have their merits, i would love a stroker for the sound, plus, its a stroker, uber torque, but the bang for your buck of the LSx series motor is undeniable, and you cant say that they dont haul ass with the right tune and mods to them. Each to their own though

[PaRaDoX]

yeah but imo the 304 has alot more low down power and sounds 100x better where the LS1 is all top end..and only sounds good once opened up and plus... we all know peak power means sh*t all! but yeah each to their own,

i suppose you could track down a vt/vx half cut (rear ended or something) and bam have all the parts you need to convert

[greenfoam]

There's LS1 VN on SC that is perhaps the best street driven VN that exsists:P if you look in the my commodore section over there and look for a dude called raap5l. It's very impressive. If you can handle spending the money on the conversion it would be a great car, 1000000000000000% legal unlike a worked 304 and much faster than a VT-VE

Nothing a Twin Screw or PD blower wouldn't fix down the track

the main thing i want to know is the engine mounts, will it be straight swap or do i gotto take it to engineers for new mounting spots?

Contact CRS, they sell the modded engine mounts.

[Blown V6 Hatch]

I agree with Greenfoam, i wouldnt spend any more money on a 355 stroker than it would cost for an LS1 conversion....If you can get the parts at trade price and build a 355 yourself then build a cheap 355, then do it but if you end up spending near the cost of an LS1 conversion, then go the LS1. Although the 304 is a good solid proven engine, the LS1 is so easy to extract power form its not even funny....

Paradox: The LS1 only lacks bottom end in STANDARD form, start modding one and its a different story.....

Back on topic, as Airstrike said contact CRS, they all the required parts.

[Doctor Sodways]

Doesnt need to be an LS1, any of the LSx series engines use the same bottom end, LS1, LS2, L98 etc...

As has been stated, the LS1 is only doughy down low when its stock, throw the right money at it and it will eat your stroker any day of the week. I agree, the stroker sounds awesome, but have you heard a cammed 6 litre running twin 3 inch exhausts, MENTAL is all there is to explain it, and i would prefer that over the older, heavier 5l block with a stroker crank. If you really wanted to go mental, look into the LSx cast iron block from GM, can make that a 9 litre, or a warhawk block if your going mental, and have bottomless pockets, either or.......

HAHAHAHA!!! 9lt, you make me laugh! Thats around 550ci if my maths is correct, of which you would need an after market block to get.

You're right it won't make 9L, the LSx block is only good for 511ci which is 8.4L.

[AirStrike]

You can but you are really pushing the bore integrity. I would never go any more then around 480ci, which would be a 4.4" stroke.

Yeah that thing is insane!

i was goin on memory and what i had read elsewhere, im fine being wrong, here is what i had read and thought nothing of it....

Available March 07

Bore 4.25 max Stroke 4.50 max 6 head bolts per cylinder (accepts 4 bolt production head to)

That size bore and stroke makes it 572.5 cu in max or 9.16 Litres















You will note that the stroke is 4.5 inch and the bore is from 4 to 4.25 inch max, when I was told about this it was said over 500 cu in however, I grabbed the calculator and bingo, 572 jumped out with over 9 Litres. But recalculation proved that wrong

Form what I see, most are going quite a bit smaller in cubes, then again one has to say here, if it take 2500 hp and you can have 572 cubes, then why not?


A video with one of the designers going over the block

Im more than happy to be proven wrong, but i was sure i read 9litres.... as i said, i read it, and thought nothing of it, im not even close to having the money to build an LSx iron blocked beast, so didnt take not of bore sizes or anything

[AirStrike]

Sorry about that mate I stand corrected, I must of been thinking of standard LS series blocks.

[Doctor Sodways]

Nah its all good, we are both slighly in the wrong, i read 9 litres, but its not quite that, but yeah, standard LS series no where close, but the LSx 'Bowtie Block' as they call them, is capable, its a learning curve for all, all i have to do, is find something to fit that tall deck into, and the money to pay for it all......

[kniever]

i read that whole thread about the ls1 transplant and **** me thats a good trnsplant, he really did a top job, i also noticed quite a few people are doing it now as there is a guy with a vp ss that did it and i think a dude in a vs also did the same conversion.

there is a bit of work and a fair bit of money involved in it so i wont be doing it for a while (cos of the money bit lol) but what i am doing is just gonna get another 5ltr VQ and save for a bit and then maybe do the transplant into that but i really still gotto do alot more reading up on everything 1st.

thanks for the info and it would be a good idea if anyone has any other info they like to add then put it in this thread so that its all in the same spot.

Sorry about that mate I stand corrected, I must of been thinking of standard LS series blocks.

thats why he put the lsx block in his post so that there was no confusion, as alot of people arent aware that they are a different block, i only found out myself a month ago when i was looking at stroking my ls1.

I think it is a great write up and maybe worthy of a sticky point so that if this ever came up again there would be no confusion.

I have seen cammed ls1's beat ls1 with pd blowers time and time again. i guess it comes down to spending money wisely and doing research into their passions before spending cash.

a ls1 can be doughy under 3krpm but replace the balancer with a different one and they can be very lively.

its alot about the tuning of your car aswell as ive know of a cammed ls1 with a twin 2 1/4 into single 3 inch making over 300rwkw. and getting 400-450km around the city
