Group A R32 Gtr Turbos?

[mr skidz]

Does anyone know exactly what spec turbochargers were used on the Australian Touring Car Gtr in the group A series?

I've read somewhere that it's the dash fives but not too sure about that, can anyone confirm?

just very curious that's all

[Hadouken]

Also heard -5's.

[Duncan]

definitely 100% not -5s, they came along about 15 years later.

there are guys on here who know what they ran for sure, but I'll bet the were big old modified bush bearing things in the original/factory housings. The R32 production Nismo and then N1 models had big bush bearing turbos and I'll bet that's what they started with.

We have to run the original turbs for racing rules and they are nasty, old fashioned things. They spool as slow as a -5 but only give the power of a -7, about 250kw at 12psi

BTW, I note the GCG website says "This Turbocharger is the turbocharger that was fitted on the Bathurst Nissan Skyline R32 GTR", and I still bet it's not true

interesting..

[Duncan]

oh I should add, the most recent race magazine had a long interview with Fred Gibson and it mentioned something about the turbos there....pretty sure it related to modified thrust bearings which also means it would have been bush not ball bearing turbos.

the magazine is a great read for anyone interested in the Gibson cars history

nice, which mag is it?

[mr skidz]

judging by the power it was making it would be fair to assume dash 5 spec but with bush bearing.

Race magazine?

[MrStabby]

judging by the power it was making it would be fair to assume dash 5 spec but with bush bearing.

Conventional wisdom is that the wheels are an older crappier design. Hence Duncan's comment about -5s coming out 15 years later.

Weren't the actual homologation cars running RS581 turbo? Sometimes referred to as Le Mans turbos?

[GT-R David]

Yes, they were running Nismo LeMans Turbos 14411-RS581. A Friend of mine has these on his R33 GTR.

Journal bearings, rated up to 640hp (flywheel hp). Bit laggy, but still nice Turbos.
