260DET Posted August 18, 2005 Share Posted August 18, 2005 For anyone interested, the latest dyno tune produced 272rwhp @6250 rpm before the injectors maxed out. Boost is presently 1.2bar, looking at ~1.5bar when bigger injectors are fitted. What seemed unusual was that it appeared that the engine would make power up to ~7500rpm, not that it will be run that high The usual turbo mods, IC, 3" exhaust. ECU is a MoTec M4, custom valve timing, ported head, stock S12 inlet and exhaust manifolds, 65mm throttle body. Engine internals are stock, except for forged Wiseco pistons and larger bigend bolts. Avatar car is a combined road/track car, not a dyno queen, lots of midrange punch to get out of the corners in a hurry Quote Link to comment Share on other sites More sharing options...

Guest PROJECTRB240SX Posted August 18, 2005 Share Posted August 18, 2005 Why Did You Choose The Disco Potato? That Is A Huge Mismatch Between Compressor And Turbine.... I Bet With A Gt2871r At The Same Boost Level You Will Probably Find Another 30+ Hp. Btw Nice Numbers And The Best Parts Is Its A Fj20!!!! I Love Those Motors.

Guest PROJECTRB240SX Posted August 18, 2005 Share Posted August 18, 2005 Right But The Gt2871r Has The Same Amount Of Response As The Gt28rs But It Has A Higher Flowing Compressor. On A Sr20det The Gt2871r .64 A/r Can Hit Full Boost In The 3500rpm Range... The Gt28rs Is The Same.... But The Gt2871r Makes More Power.

Guest PROJECTRB240SX Posted August 18, 2005 Share Posted August 18, 2005 GT28RS .86 A/R: GT2871R .64 A/R: IGNORE THE 400HP DYNO.... DIFFERENT TURBO. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 18, 2005 Share Posted August 18, 2005 All this proves is 2 different dyno's read differently.... without using the same car and the same dyno there isn't much point... Quote Link to comment Share on other sites More sharing options...
Guest PROJECTRB240SX Posted August 18, 2005 Share Posted August 18, 2005 Its Been Proven Over And Over Though.... Well Its All Up To The Owner Of The Vehicle, But My Opinion Is That The Gt28rs Is Not Great At All. Btw: That Is The Same Car. It Was Done By Scott At Enthapy.

Drax240z Posted August 18, 2005 Share Posted August 18, 2005 Just looks like apples and oranges to me... .64AR vs. .86AR... 2 different dynos... A better comparison would be to post the compressor maps of each turbo and compare those. At least that is comparing apples to apples.

Guest PROJECTRB240SX Posted August 18, 2005 Share Posted August 18, 2005 gt2871r gt28rs the reason its a .86 a/r turbine against a .64 is because the gt28rs only comes in .86 and a fair comparison would be the .64 2871r vs. the gt28rs.

260DET Posted August 19, 2005 Author Share Posted August 19, 2005 Why the disco spud? Several reasons - I know SFA about turbos, the price was right, it produces a wide spread of torque, conflicting advice re alternatives, don't want more than 300rwhp so as to preserve the transmission......... No comparison between it and the former hi-flow TO3 Pic of donk here. Quote Link to comment Share on other sites More sharing options...

rb26zed Posted August 19, 2005 Share Posted August 19, 2005 I like the swap too! I thought about using an FJ in mine for quite a while (till the '26 came up at the right time and price) I always liked the idea of the lower weight and keeping the engine behind crossmember.
