355 stroker/gen 3 conversion/boost?
hi guys,
just tossing up some ideas about making the clubby go a bit better and want to get some opinions on what to do. I have about 6 k to throw at it atm hopefully a bit more soon.
I can get a pavtek 355 with 440hp for 5,900, can prolly build one myself cheaper by buying the parts and getting it built..
or I could do a gen 3 conversion for around the same? just running the t5 behind it till I can afford the 6spd conversion (have heard this is possible). unsure of exact cost of this, prices I've looked at are from a few years ago..
or I could do a quick rebuild of my engine and beef it up a bit and bolt a turbo on..
just wanting some opinions on what would be the best for the money and the most reliable. I'm pretty good with the mechanical side of things, can do alot of stuff myself.. just want a tuff street car that's reliable and goes well..
any help would be great, cheers.
by gen 3 conversion i assume your talking about and ls1. heres a thread on one. he says hes already spent 11k and counting...
Sam's VN Lexxxcen LS1 T56
dont sweat the petty... pet the sweaty...
yeah I've browsed over that thread.. conversion can be done way cheaper than 11k, though he's taking it to another level. pretty cool ride if u ask me.
you wont get a gen3 in there for under 8k, i thought long and hard about doing it, there is too much to be done, it was costing me 4k for the motor. box computer and harness alone. sam ended up spending 15, thats on the road, running, everything done. by far it would be the most reliable option out of them all. if it was me, chuck decent cam in it, high compression, 3;73s or 3;9 LSD and it would be pretty lethal.
another option, chuck a RB25T in it, gearbox mount is slightly diffrent, if you can weld you can fix that, VL K frame, vl engine mounts, custom dump pipe, front mount, 3;9s. your all set.
If you're not driving a manual, you are only steering, not driving
Go the gen 3, more aftermarket go fast parts.

Do the LS1, so many more options, including twin snails down the line

Well im in the process of building a turbo 355 capable of handling 25psi all day long and I have all the parts here which cost me $7000. The only thing I didn't pay for was the block which I already had.
With head work (not included in the price above) it would easy see 550rwkw with a stronger box.
The T5's don't handle all that much power compared to their bigger brother the T56.
I was in a workshop the other day where a bloke was doing an LS1 conversion to a VS Ute and he said there was 2.5k just in conversion parts which I thought was fairly reasonable?
Money plays a big part in a build for obvious reasons. A mate of mine has a 355 and he spent 8k just on the bottom end and he only gets 450 rwhp (N/A) but nothing could kill it.
I also toyed with the idea of an LS1 in my ute but I know how to work on the 304's and I can focus more on the engine and avoid the stress of making the LS1 fit.
Either way your going to be happy with what you do, but after buying all these parts and the power that it can produce verse whats street-able has made me wish I just went with a 2j instead.
Does anyone know how hard it would be to get the LS through regency!? this is sounding like the better option.. I think I can get a motor, loom an computer for round 3 and the CRS conversion kit for 1300.. can't be too much more ontop of that if I do alot myself?
2.5 k on the conversion.. wonder what else Is needed for it??
they must be some bulletproof engines you guys are building!
Why don't ya just rebuild it and chuck on a supercharger
Just cos my engine needs to be freshened up or it'll go bang, and every other vn/vp 5lt has charger on them.. want somethin different.

Not many engines can make 500kw on stock internals....

Pavtek 355 for sure man... 330rwkw with 568nm torque - bloody awesome motor.
Only thing you'll have to watch though is you'll need the rest of the driveline strengthened to be able to cope with that power going down it.
have never heard of a 2j motor b4 that thing looks lethal!!!
and yeah the pavtek 355 is a killa engine, so if have to beef the box and diff up strait away I spose..

You won't get a motor built cheaper than what pavtek can sell you one unless you build it yourself. The price you quoted is an exchange price too, you have to supply block and heads. And that motor won't get 330rwkw, the more expensive ones like mine yes but not the cheaper one in your budget. In the end your budget doesn't stretch far enough for any of the suggested options other than a simple rebuild with some mild work. What you need to know is how much power you want to make and then plan how to get it. In your case I would get a rebuild with quality parts and some decent pistons, throw in a mild cam that would be ok for boost and then chuck a turbo on it when you can afford to running sensible boost. If you can build turbo manifolds and such then it would be cheaper but eze 10's make a good kit. With a fresh motor to standard specs but forged pistons and a mild cam it should safely handle 10-15 psi day in, day out and make 300kw at the treads easy enough providing you have a decent tune. But for now I would just get the rebuild sorted or save up some more coin.
Cheap, fast, reliable.....you only get to choose two.
I'd be doing alot of work myself whatever it is, as well as saving money as I go..I know i dont have 15k to slap strait on the counter at a shop and say "build such and such for me" like some ppl might, it's just going to be a bit longer process for me to do it myself. my old mans shed is pretty well set up, hoist, pit heaps of tools and between both of us we could sort out pretty much everything.
I just need to work out what's the best option for me, I want something that Is reliable and worth the time and money.

i agree with the supra conversion,that thing is a monster,and its only single turbo,imagine that thing as twin turbo,you would probably blow yourself to pieces but at least you would have a good time doing it lol they called that thing the supradore,and if you went with that engine i wouldnt complain,jap motors are built well,also seen skyline and silvia motor conversions RB25 - RB30 would be nuts,only thing is some of them are built for AWD,would be an awesome build if you could achieve it,good luck though mate,whichever engine you choose it should be a weapon either way

go the ls1 and down the track slap a snail on it:-) cheapest way in the long run. Very steetable and make plenty of ponies.

Supra engines are hands down more reliable and stronger then any of the RB or LS engines. Yeah you could throw a turbo on an LS engine but its only going to do damage to the bottom end if you turn up the boost.
You see allot of Nissan drift cars with 1j and 2j conversions now for obvious reasons.
1000hp with stock internals is a good deal. If it goes bang then throw it out and spend another $1000 on a new bottom end.
Not to sure what old mate is on about with the twin set up, twin turbos will still only produce the same boost as a single, and in actual fact your much better of with a single not only for punch, but it wont foul the brake booster if you decide to drop one in.
Everything a 1j and 2j's are capable of are all thanks to bolt on parts.... So its easier on the wallet at the end of the day.
If your serious look into a front cut that has the R154 box. These things are very strong.
Things you'l need.

that vn with the 2jz is bananas... whats the power in that car?
edit: answered my own question reading the comments...

so the skyline engines are good enough for the VLs but not in a VN? those things are mental with the right setup,im not saying do it and ignore an LS1 coz those are an awesome motor too,just saying it would be different to go with
America just kicked in yo
RB26 is almost a straight bolt in and fits the bay because vn-vs was designed with the rb30 intended for use, not sure about the difficulty of 1j or 2j fitment, my heart always screams v8 though lol

theres nothing like that sound i agree...
