Cheap Turbo Kit

[V35DRIVER]

I have been thinking about getting a turbo installed on the V35

Now i can easilly go out and get for $4000 Though has anyone thought about purchasing everything seperatly.... turbo, intercooler, piping, etc.....

i have come across these cheap ball bearing turbos for $400 would any of you guys buy one????? or are cheap turbos really shit?

[NISMØ]

The cheapest turbo that will 'work' without failure is probly a KKR or a High-Flow, dont be fooled into buying one of those cheap T04E/T70 turbo's of ebay / other sale points as they are almost always very dodgy. If your on a budget you could try and find a Second hand Garrett or get a KKR Turbo (only get genuine KKR from otomoto) not the ebay KKR as they are fake. XR6 Turbo Specced Garrett Turbo's are pretty cheap and would be nice for the VQ35 imo with the 1.06 (i think it is 1.06) would come on pretty early in a properly tuned VQ35. Exhaust manifolds , CAI etc would probly have to be custom made or bought new.

Hey, you are better off getting a supercharger for the V coz not much is needed in regards to fitting and pipe work. And also turbos work better with a low compression engine, our V's run on a high compression engine again thus making it easier and cheaper to get a supercharger. However if you really want to get a turbo, spare yourself the trouble now and get a proper turbo e.g garrett, hks, apexi. I once got a cheap turbo from china for my old r33 and literally it lasted 2 weeks. They don't work well when under high heat. I ended up buying a gt30/35. I would have saved myself 1,500 plus labor.

Please explain how the engine's compression ratio makes a material difference to what kind of unit compresses the air going into it.

thanks guys for all the opinions!

i will most likely go buy a kkr or second hand garret.....

cheers

I can't understand that either.

Oh ok, what i meant to say was that lower compression engines will work better with both turbocharger and supercharger because of the extra boost that will be coming into the engine. However, the V's run on high compression thus giving you power when you rev up the car. The supercharger will be easier to install because they have fewer components and parts while on the other part turbochargars are complex having to modify the manifold, exhaust, intercoolers, additonal oil lines. But at the end of the day its up to you. You will probably need a expert mechanic to install the turbo. The supercharger would work cheaper in my opinion on a N/A car.

[scathing]

That honestly depends on how much boost you want to run.

Half a bar of boost will see you to around 280rwkW on most twin turbo kits with a very linear power deliery (the ones I've driven have felt like stock R33 GTS-ts/S15s in terms of how it feels across its rev band, just a shedload faster), and I know guys who've daily driven their TT 350Zs for years without engine strife.

The higher compression means it's far more responsive and economical than a stock turbo'ed car. It's why a lot of modern manufacturers have gone the high compression/low boost route to deliver good drivability for their cooking models while keeping fuel consumption down.

The supercharger will be easier to install, I'd agree. If you're only after a small power hike (but more than what bolt-ons can offer) it's hard to beat a supercharger. The 230rwkW HKS Rotrex'ed 350Z felt like the engine had just been embiggened, but superchargers are inherently less efficient than turbochargers and centrifugal ones are the worst of the lot.

[Stephen Thorpe]

TT sounds the go for me, low boost is stll enough for these to work.

Nicely said Scathing.. with the big engine on the V you don't need to run a lot of boost into the engine to get some good power, 280rkw is pretty good. So if your on a budget go for the supercharger and if you have the $$$$ to spend go for the turbocharger. If i was in the $$$$, would probably look at fitting a supercharger to deal with the lower revs while the turbo takes over the at the higher rev band. I found a good article about superchargers and turbochargers check this out:

Is there room in the engine bay for both a Supercharger and a Turbo?

Would be good though...

You can sit a centrifigual supercharger where the factory airbox sits, or mount a screw type between the V like Stillen does. You can run single or twin turbos as usual.

The main question is whether you can everything plumbed in. The bends to get a turbo kit to fit look like a rat's warren.

I'm also not seeing people's current fascination with twincharging. The APS/GReddy/PE twin turbo kits for the VQ35DE deliver plenty of tractability down low and will still flow 400rwkW with the right supporting mods. I've driven 350Zs with around 300rwkW and down low they still pull strongly enough. It doesn't feel any worse than my NA car at any point in the rev range.

The cost of getting a supercharger kit would pay for a VQ37HR crank and custom internals to fit a VQ35DE (you can choose whether you want to drop the compression ratio and up the boost or keep the ratio high and retain response), which will give you more stroke and thus low-end, and the custom plumbing required for twincharging would pay for at least a set of cams.

Cool... seems like lots of trouble, especially to plumb it all in.

I wonder if the VW 1.4 FSI would work...

Think I might stick with one or the other, if I can find the coin.

just having a read of the above comments, quite interesting

what kind of times are we looking at 0-100?

turbo vs super charger?

[I GOT RICE]

how much for a quality twin turbo kit for the v35's.... including all components? what mods would need to be done to the stock car to strengthen it/ handle the turbo's? i was aiming for mid-low 13's down the quarter?

would you need upgraded injectors, ECU, internals?

[Tebie]

it would cost big money for a twin turbo set up and to strengthen the internals just for a mid 13 sec car...

* you would probably need to upgrade the injectors, im not sure what the standard injectors are rated at but im pretty sure they wouldnt be sufficent enough for a turbo charged set up.

* you would definately need to copgy back the stock ecu, if that is possible. i dunno if re-mapping is an option but if none of those options are available you would definately need to change the ecu.

* you wouldnt need to change the internals, but it would be good idea...

and a 2nd hand garrett turbo is always going to better than any kkr turbo. the cheaper you keep the set up costs, the more problems your bound to have with the set up. your better off getting quality parts from the start if you want to turbocharge your non turbo engine...

i would choose to supercharge my car if were looking at boosting my engine. less hassles and by the looks of things alot cheaper...
