mellonman Posted October 16, 2011 Share Posted October 16, 2011 there must be threads out there covering this but i cant find them, how do you know what turbo to get for a single conversion? what turbo and a/r is good for 450-500 bhp.

johnny g Posted October 16, 2011 Share Posted October 16, 2011 Whifbitz Twin Scroll T4 setup, with a GTX35R would be very fast spooling and 500bhp easy at low boost. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 16, 2011 Share Posted October 16, 2011 A/R in a nutshell, the lower the a/r number the faster the spool but you lose out at high revs. Explained here :- http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech102.html#b Quote Link to comment Share on other sites More sharing options...
Bailey. Posted October 16, 2011 Share Posted October 16, 2011 something like this would meet your needs, but are you sure you wont want more power once you go single. either ar would be very quick spooling. And bb would have super quick spool, http://www.spracingonline.com/store/Precision_58mm_CEA_Billet_Turbo_5857/3689 Quote Link to comment Share on other sites More sharing options...

j_jza80 Posted October 16, 2011 Share Posted October 16, 2011 A GTX30R should do this, with very quick spool. Quote Link to comment Share on other sites More sharing options...

mellonman Posted October 16, 2011 Author Share Posted October 16, 2011 thing is with the phr kit import tax and shipping do you remember how much it set you back? Quote Link to comment Share on other sites More sharing options...
heckler Posted October 16, 2011 Share Posted October 16, 2011 thing is with the phr kit import tax and shipping do you remember how much it set you back? unfortunatly I was lucky, I got it "second hand" although it was new and never fitted for £1600 - and mine is a cast manifold, not the tubular like it is now....

JamieP Posted October 16, 2011 Share Posted October 16, 2011 thing is with the phr kit import tax and shipping do you remember how much it set you back? You got vat and import duty, together about 20% i think on the cost of the kit which is £2300-2400 i guess, would cost you itro £3000, I hear there is ways round the import duty though.

Bailey. Posted October 16, 2011 Share Posted October 16, 2011 Just ask them to put the cost of the parcel through as lower to the shipping company. I paid £135 for a pacel that was $800 about 6 months ago.however if it was lost during shipping I imagine you would only get back the price that was told to the shipping company, not sure it's worth the risk on such a pricey item.

I haven't admitted to anything, I know people that have, this was for my bc valve springs, vss and lockers, oil drain setup and arp head studs. Canes to around $780 iirc!
