Title: HKS GT2530 upgrade for twins in fd?
Post by: L18M on August 14, 2010, 10:14:15 AM
Just wondering how well it would be to use twin hsk gt2530 as an upgrade to the twins?
i\'ve heard of people using twin bnr stage 3 as upgrades but not heard of gt2530 being used.

i dont know much about fd\'s and am asking for a mate.

cheers.

I think i\'ve seen it done, obviously it\'s non sequential so the lag is the same for similar power on a single.

I had the garrett versions on my GTR a while back.  2860-5\'s
 
They spool very quick and you can run them at 1.9bar
 
I then went 2860-10 which is the same back end but bigger compressor, they are the same as HKS GTRS turbos. rated to 800bhp in piston terms (really max out at 700-750ish) so rotary 600bhp i would say.  but the exhaust is only a T25 foot print with a .64ar so small.

if you\'re talking about bolting some aftermarket turbos onto the sequential mechanism thing then i can\'t see it being easy. the \'easiest\' way to upgrade them would be to find/machine some larger compressor wheels and housings, which again is going to be more difficult than it\'s worth.
 
the problem is the exhaust side; the housing isn\'t your typical turbine housing and is engineered into the sequential system. if you had a machine shop to use you could probably fab something up, but it\'s a lot of effort.
