bolt on turbo upgrades?

[Madhav]

from what I heard.. dont bother with the stock GTR or GT-T, GTS turbos unless they're the model out of the N1's

and I thought the GTR turbo's are identical to the GT2554's?!

Some dude in Russia put N1 turbos on his vr4, there is a dyno shot, but no boost pressure vs rpm. Check here

Couldn't see a post regarding this, is there a turbo that is basically a ball bearing version of the stock turbo? No exhaust manifolds or anything, literally a direct swap. Any experience with this or do I just get a replacement stock turbo

 

[chocco]

No such thing as a replacement...

Dig deep if you wanna change the stock turbos

 

[Tophler]

just after something that wont detonate under the bonnet but still maintains the stock boost and all the other characteristics. Thanks for the info though

 

[fieldy107]

Why would our turbos detonate? they are pretty tough little units.

 

[chocco]

Dont be mistaken by mitsubitshi turbos lol they are a decent unit and work well given
the fact they are small and in a tight place. They are designed for the car and do respond
very well with some mods to extract more power.

If your after something more friendly to work on, swap turbos when you wish, do this and
do that without hurting the bank account...the vr4 was a bad choice for you.

 

[Tophler]

No I do like the vr4 I've just heard bad things about ceramic turbos detonating on high boost. I know I know keep the boost low but even still is there a chance they will explode? I've heard either replace or rebuild them after 100,000

Huh? Who's telling you this? Our TD03's have a steel turbine wheel not a ceramic wheel. I think your sources are confusing a Legnum with a M35 Stagea.
- 145 000 km and stock turbos here. Steve has over 200 000km on his turbos and we run 16 psi

 

[Tophler]

I do apologise and I'm grateful for all the information

 

[Guest]

These td03s are strong snails!! Iv done 275thou on a stock motor and turbos running 16psi and a few mods, no Imternals..
when I blew the motor I pulled over lifted bonnet,front turbo was glowing orange and I could only assu e what the rear looked like , I somehow dropped cylinder 1 in a way that I started the car and told AA to meet me 100km at a small town. So I drove with a screwed set of turbos,5 cylinders and no cooling apart from air movement fir an extra hour.. A few years now and I still have that motor lol and the turbos, bearings are fine but units suffered extreme heat..

jon is doing manifold upgrades for larger turbo options isn't he? Just go that way. Otherwise simply flash your Ecu if u want more power, see Steve for that

 

[Tophler]

If I was to go down the path of bigger turbos do I need to upgrade the ecu or can the stock one handle it

 

[qball]

stock is fine

Old thread, but most relevant.

For anyone who is game. Very game...

 

[96vr4]

You must be chasing some serious power

 

[SLY-031]

Hence the being 'game' bit. These would make very large numbers with the right supporting mods.

Packaging would be a bit tighter than yours, but definitely do-able.

 

[TME_Steve]

You'd need to do a LOT of work to the heads to get them to flow enough for those to work well....

 

[jungle]

Yep. Fit the biggest exhaust valve you can at least +1mm and port work, there is a decent amount to be gained if you're prepared to spend the time

 

[SLY-031]

What is the valve sizing etc like on the 6A compared to a 26? Has anyone looked at it before?

 

[jungle]

6A is 28mm
RB 26 is 30.15mm
But there's more to it than exhaust valve size alone

 

[Donkay]

Already done on my old car, twin Td05 16g (search thread on build)
definetly needs more flow on exhaust
