s30red240z Posted November 30, 2010 Share Posted November 30, 2010 In a 3.0 liters engine with some internals modifications, which is better?. Better power band, better spoon at less rpm, and more flow at less psi? Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted December 1, 2010 Share Posted December 1, 2010 Get the equivalent of a 3076. Quote Link to comment Share on other sites More sharing options...
bradyzq Posted December 1, 2010 Share Posted December 1, 2010 In a 3.0 liters engine with some internals modifications, which is better?. Better power band, better spoon at less rpm, and more flow at less psi? I love good spoon! What are you looking for? Quick spooling that will die off a little early, or something that spools a bit later but that can effieciently pound out the lbs/hr at high revs? What redline RPM are you planning?

B00STDZ Posted December 4, 2010 Share Posted December 4, 2010 (edited) Ahh ive been looking at turbos too here litely... Either the t3/t67 HO Ball bearing or Check out the Precision PT 6776RSP (ported shroud for better efficiency, ball bearing, same size as t3/t67 HO, good for 50 more whp than the t3/t67 HO DBB) Both supposidly the same? No one has gone this big on t3/t4 hybrid turbos on this forum so Im not sure how it would respond to the L series... the precision turbo is good for 750 wheel... they say the t3/t67 is only good for 700 whp...

B00STDZ Posted December 4, 2010 Share Posted December 4, 2010 Heres the precision turbo... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=160507868203&viewitem=&sspagename=STRK%3AMEWAX%3AIT Heres the t3/t67 HO DBB http://www.full-race.com/catalog/product_info.php?products_id=1107 They are VERY close in price... but accually I will probably buy the precision for the ported shroud(the little holes on the intake, allow for the turbo to hit its efficiency range easier) Massive turbo honda guys have been running little engines with big turbos/ported shrouds for ages and made 9 sec cars...

I used a T67 for the build in the 3 liter stroker in the 510 ,the BB T67 spools by 4k rpm and pulls VERY hard once in boost. The turbo is/was even being used on a mostly stock L28 with 7.5 -9.5 psi , the turbo spools fine on the smaller engine .

ShaggyZ Posted December 8, 2010 Share Posted December 8, 2010 My .02 - I've finally come to understand turbo response is more important than when in the RPM range it begins to spool, unless you're making just a drag car. The turbo I choose will be based on that. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted December 8, 2010 Share Posted December 8, 2010 510six, how much boost was used in those dyno plots? Quote Link to comment Share on other sites More sharing options...
510six Posted December 9, 2010 Share Posted December 9, 2010 510six, how much boost was used in those dyno plots? 17 psi, the clutch slipped at 440 rwh and 18 psi. We were on the way to 500rwh (the goal). Quote Link to comment Share on other sites More sharing options...
Matt K Posted December 9, 2010 Share Posted December 9, 2010 (edited) BTW, Full-Race can get any of their turbos ported as well. I had my GT3567R get a ported shroud, polished compressor, and ceramic coated turbine section... Edited December 9, 2010 by Matt K Quote Link to comment Share on other sites More sharing options...
s30red240z Posted December 9, 2010 Author Share Posted December 9, 2010 i am still undecided, my engine will be VG33E engine, 1000cc injectors, ported heads, .420 270/262 camshafts. and i don't have enough money for Dual ball bearing Quote Link to comment Share on other sites More sharing options...

The plain bearing unit from Limit with a stage 5 exhaust wheel was under a grand in cost and is quite capable of making big horsepower. http://www.limitengineering.com/ Quote Link to comment Share on other sites More sharing options...
