hellraiser Posted June 10, 2005 Share Posted June 10, 2005 i got my bare block and want to get about 450-75hp out of it was told to go with 550 cc injectors, and a gt30r turbo but they are kind of high , price wise, so my question is what do u guys think about the t04e from garrett or any suggestions to get me to the range im looking for, already got my 90mm throttle body and planing on using the greddy intake unless someone knows a cheaper intake to go with, these swaps really drain the pockets.

drunkenmaster Posted June 10, 2005 Share Posted June 10, 2005 You would be silly to go for a 30 year old T04 design when brand new GT30 and GT35's are around for such reasonable prices. I would be thinking GT35 with a 0.82A/R housing for your power goals. It maybe not boost as early as you would hope (although the 0.82 over the 1.06 housing will help), but thats the cost of big power small capacity motors. The ball bearing GT series will spool much faster than the T04 as well. Quote Link to comment Share on other sites More sharing options...
hellraiser Posted June 12, 2005 Author Share Posted June 12, 2005 most likely ill go with the gt30r, but im new to turbo set ups so i was looking for advice of members with more experience, the gt35 seems too big or am i wrong Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted June 12, 2005 Share Posted June 12, 2005 You can save some dough and go with a standard GT30 or GT35. Drop the ball-bearings(the R in the turbo name). From my understanding ball bearing turbos can't be rebuilt. So, that is one plus to going no BB. The GT series spool faster than the old ones also. So everyone knows, not all GT series Garretts are ball bearing. Also, for 475 at the wheels, you'll want bigger than 550 cc injectors. The Greddy intake looks like a very nice unit. And as for the price, It seems like a good deal to me. I paid that much for a 5.0 Mustang "GT40" intake 10 years ago. Quote Link to comment Share on other sites More sharing options...
hellraiser Posted June 13, 2005 Author Share Posted June 13, 2005 the ball bearings are sopposed to be the latest tech and hard to break and the lag is pretty minimal ive read. with constant oil change and good coling its sopposed to last as long as the motor,so ive read does any one have one of these turbos and can compare the gt to the gt-r's, ive been cheap before with parts and its bit me in the butte, so this time i want to do it right from the beggining Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted June 13, 2005 Share Posted June 13, 2005 I would definitely use a BB turbo, as far as I know they are rebuildable at a price but since you are buying new you shouldnt have to worry about rebuilding it. The argument is similar to EFI cars being more expensive or difficult to repair. Quote Link to comment Share on other sites More sharing options...
ZXRockie Posted June 15, 2005 Share Posted June 15, 2005 Is this like top mount or t25 flange? Quote Link to comment Share on other sites More sharing options...
hellraiser Posted June 16, 2005 Author Share Posted June 16, 2005 yeah top mount t3/t4 flange Quote Link to comment Share on other sites More sharing options...
Guest Benito Posted June 23, 2005 Share Posted June 23, 2005 Are these the reccomendations for the stock exhaust manifold? I am under the assumption that the stock mani will work with the swap and these turbos are the ones that you are reccomending for it? If not, which turbo would you reccomend to use in conjunction with the stock mani, preferably internally gated, with a 425+ hp goal on pump gas (93 octane)? still the bb gt30r? hks series BB? t3/t4? *edit* And if you don't mind, a good website with a cheap price, too.

drunkenmaster Posted June 24, 2005 Share Posted June 24, 2005 All the GT3X turbos have the correct T3 flange for the stock manifold to my knowledge. Gt30's and 35's can be custom assembled by garrett with internally gated exhaust housings which is what you would want with the stock manifold unless you want to cut and shut and external gate to the exhaust which is a bit suspect in my opinion.

ZXRockie Posted June 24, 2005 Share Posted June 24, 2005 cheapturbos.com , turbocalculator.com , there is a guy here that sales turbos he is the guy doing a red rb26dett twin top mount turbo. gt30 is mounted in t3 header flange... and the gt series from garret are Ball bearing, gt2530 is a garret made HKS spec turbo... hope I helped somehow...

Guest PROJECTRB240SX Posted June 24, 2005 Share Posted June 24, 2005 I've Been Fond Of The Gt3076rls With The .64 A/r Turbine For The Rb20det So For The Rb25det I'd Get The .86 A/r ... Its Fast Spooling With A Flow Capacity Of Over 500hp. Quote Link to comment Share on other sites More sharing options...
Montoya Posted June 25, 2005 Share Posted June 25, 2005 We run Garret GT series turbos on our pro RWD drag car and I must say they have been the most reliable turbos we have ever used. The Ball Bearing turbos are fully rebuildable for not a lot more money and they spool much faster then a standard bushing style. Garret will be releasing a GT35R with an internal wastegate very soon (if they haven't yet). I would recomend this turbo as it is capable of 500 HP, spools very quickly on a 2.5L, will have the wastegate sized perfectly, and is one of the highest quality turbos on the market. Just my $.02 Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted June 26, 2005 Share Posted June 26, 2005 Somewhat related question! Do you guys know on the stock RB25DET (ECR33), is this turbo T3 flanged? I know it's a T28, but is it T2 or T3 flanged? I know some turbos can come in T28 form with a T3 flange. Someone please please help me out on this. My main thing would be "Could I bolt up a T3 i.e. GT35R turbo to the stock manifold?" or am I just limited to the T2 flanged turbos only on the stock manifold?

cheftrd Posted June 27, 2005 Share Posted June 27, 2005 The RB25 uses a T3 flange. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted June 27, 2005 Share Posted June 27, 2005 The RB25 uses a T3 flange. Thanks for the info... would you think a GT3071 [T3] Flange would fit on the RB stock manifold in the S30 with any clearance issues? Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted June 27, 2005 Share Posted June 27, 2005 Actually, if anyone has any connections on a GT3071R or a GT3076R with a T3 Internally Regulated turbo let me know. Quote Link to comment Share on other sites More sharing options...
S15 200sx owner Posted June 28, 2005 Share Posted June 28, 2005 Actually, if anyone has any connections on a GT3071R or a GT3076R with a T3 Internally Regulated turbo let me know. Try James Thegard (240z turbo) on this site. Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted June 29, 2005 Share Posted June 29, 2005 Another question for everyone. #1) Should I even think about running a GT3 series turbo with an internal wastegate? I hear sometimes these turbos can come on boost really soon and can cause problems when internally wastegated. #2) Besides the HKS Cast manifold, are there any other good choices/recommendations on manifolds for the 25 with a decent external wastegate setup? I won't even consider the SS Autochrome pieces or anything that looks chinawelded. -Thanks Guyss! Quote Link to comment Share on other sites More sharing options...
