Anyone done it?

 

Been chatting to someone and they reckon you can get the kits with the turbo for about 2K and one big turbo is better than 2 ??

i was wondering this too. ^^ hope your back :hyper:

apparently with 2 turbos you get the infamous lag......

 

1 turbo with a wastegate is the way forward??

 

Come on surely someone's done it or thought about it??

 

me back? yeah its fine thanks :tongue:

Be an interesting set up on a V6 rather than the usual conversions on a straight 6. Single big turbo can give alot more power but can be a bit laggy if not done right. There are alot of site with a single conversions on a n/a but haven't found any for a TT, these might be good place to start.

2 smaller tubs have less lag than one big one

Have a look at these

:shock:

What about two big turbos after all 2 is better than one :shock:

my capri 280 f16-turbo technics 240 b.h.p.(with a garrett t3) and i can vouch for the single big turbo producing more lag than two smaller ones.as nice as she was the lag was a tad noticable in her compared to my zed until aboout 1250 onwards it was just like a weezy n/a cologne 2.8 but when it kicked it kicked big time and was a handfull in top boost mode but that was more the aged chassis and suspension unable to cope with the power.where as the zed delivers a smoother power uptake and has a chassis/suspension able to cope with it.

longlive me zed

chris e boy.

Has anyone done the small turbo backed up by the bigger one so it eliminates lag like ive seen on some trick skylines.

The chassis on my old 1.6 laser capri had trouble handling 70bhp so god knows what your 240bhp 280 brooklands handled like good for going sideways.

You cannot beat the old leaf spring and live axle set up on the capri you didnt need a steering wheel just floor it for turning :smash:

t`was truly an art form keeping that old girl on the straight and narrow.

still it was good fun while i had her.

its getting the balancing correct, as the engine is a v type engine its more suited to its twin turbo setup. although the z31 was v6 single turbo, its not a touch on the z32 Twin turbo, im sure with the fabrication and setup it may be suitable

 

you would need an exhaust running from one side to the other for a start, as theres very little room at the rear, it would probably need to be run around the front some how

good old american horsepower LMAO

Unless your wanting to go over 600hp I can see no point in the expense required to go single turbo, It will be laggy and you will need to spend serious money on the engine to support the power at that level.

The only way around lag, is with hybrid turbos, where you get faster spooling +big power.Single big turbos always seem a bit of a compromise to me, to make them work on the road.

My son and I are just collecting the parts to onvert his R33 GTR to a single. From our investigation we think that if you try fitting an old truck turbo like T88 or similar then yes you are going to get late spool up times, and a big kick when it does boost. Which is fun but boring in the end.

 

However, a new tech turbo can be better than two singles, both in terms of lag (spool time) and power. But the A/R and housings also need consideration as these too affect spooling/power.

 

Not sure its worth the bother on a Z. IMHO

Stick with 2 tubs athene, if your considering 2k, then you would get some decent high powered ones for that money which would bolt straight on, no probs.

The Z engine is literaly 2 x 1.5cc engines, using 1 big one to try and balance the 2 sides is a lot of work for the type of driving any of us would normally do, including track. The skyline however being a straight 6, can get away with just 1 turbo and many do it as well.

gotcha... . thanks for clearing that up!

 

this chap i was talking to about it was sure it had been done on a zed and it was worth it blah blah .... so just wanted to check with 'the brains'

no way .... they only way you ae going to get single turbos to spool as quick as a twin set up is by using a variable vein turbo - and as far as i am aware they only one for petrol cars is a borg-warner design which is sold exclusively to porsche. you can get more power out of a single but my 2p is if you want a driveable car go for a for a ball bearing twin set up.

Not actually true, some of the latest dual BB turbos spool up amazingly quickly, for example the T04Z that a friend of mine has on his skyline hits full boost which is 1.6 bar by 3400 revs and makes just over 600 AWHP which is about 750-800 at the fly and jesus it makes for one mazing street car, also some of the supra buys using the new garrett 4080 turbos are getting full boost under 3000 revs.

 

With regards to the zed, as its been said its just not design friendly to try it, yes its possible but by the time you run a manifold round to the passanger side, then fabricate it to go where the AC comp goes, them you need either a single plenum or run the twin plenum into a twin in and single out intercooler, then theres the problem of the radiator position etc etc so for £2k!!! i dont think so, i think once you start adding it up it will cost quite a few times more than that, but its certainly possible but i would stick with a pair of twins :)

yes, my view too. It does have to be a ball bearing turbo and one of the newer designs....

yes 1 big turbo would be much better than 2 less lag and more upfront power the kits are available but very expensive

any v engine is better suited to twin turbos, unless you are going drag racing! I had an XR4X4 turbo technics single turbo and my mate has a 3.9 v8 rover single turbo. they are a compromise.

No, typically 1 big turbo = more lag, longer to spool..etc.....but potentially more peak power.

 

There are no "kits" available for the Z32. It wold have to be completely custom, and very expensive.

Also quite a few of the Landrover diesel engines (aka bmw units) use variable vane turbo's.
