twin GT2871R's w/ .63 turbines?? maybe even the .86 if you can take the lag, but if you can take the lag get the twin GT3071R's, each good for 400+, uses the standard T25 turbine flange GT3071RWg - 450hp http://www.atpturbo.com/Merchant2/merchant...tegory_Code=GRT www.atpturbo.com - 3071R makign 400awhp on the 1.8 audi's www.cheapturbo.com - garretts at great prices.

i had 260* 8.8mm lift ProCams in my CA19DET and there was a little low end loss, but screamed from 4500rpm-8000rpm, i wanted to go with TOMEI ProCams 256* 8.5 IN and 260* 8.8 EX cams, TOMEI valve springs and Gears on the RB i am planning on building next. i am hopeing to lower the lowend/midrange grunt a little and i have been told this is a safe turbo cam set up, with my 260* pairs i had slight overlap dialed in... similar setups are poplular wiht the HKS cam kits as you can get different lifts/Steps with the same duration... but i too wish to keep hyraulic lifters.... so we'll see...

HI all i have been lookign into putting together a RB20DET engine and have already read up on the potential of the engine.. here is what i plan please let me know what you think: RB20DET w/ 5 Speed (new water pump, tensioners, lifters & gasket kit) *T3/T04E - 50 Trim .50A/R T04E compressor, .63A/R stage 3 Internally gated 76trim T31 turbne HKS Actuator *GT Core FMIC kit (20"x12"x3" core) *Blitz Nur Spec Racing Exhaust, cusotm 80mm 02->Down pipe, *80mm Downpipe, *test pipe (cat replacement) *Haltech E6k w/ 3bar map *6 x 550cc RC Engineering Injectors *Walbro 255lph HPFP *Aeromotive FPR TOMEI 1.2mm Headgasket TOMEI ProCams 254* 8.5 IN, 260* 8.8 EX TOMEI Cam Gears TOMEI Timing Belt Tomei Valve Springs *3 core Copper Radiator *Twin 10" Electric Fans 400ft/lbs Clutch Kit - ?? Aluminum Lightweight Flywheel - ?? * Are parts i already have Questions: Is there clearence for the T3/T04E hybrid turbo under the stock manifold? should i go with a smaller A/R turbine for quicker low end response from 3000-7000rpm instead of 4000-7000rpm? is that a good cam combo? i had the exact set up on the CA except for 260's on both IN and EX and it losta little low end... i'm thinking the 256* IN would keep a little low end grunt... Custom Intake Manifold? i wanted to unbolt the top half of the intake manifold - and weld a plenum on there so i can put my TB near to where my piping is currently... I am running a haltech so no MAF's... and my roomate runs a fabrication shop so i can get work doen cheap and easy and very well done... either that or cut the over engine intake and re weld it onto teh side of the plenum like i see many do... What Clutch & Flywheel Combo?? Are the CA18DET & RB20DET coil packs and Cam Angle Sensors the same? what do you think of my set up and what could i expect? What is i did the same set up on the RB25DET? this will be built on the side, then installed, just liek my other projects... thanks - i have been browsing the forums for a lil while and now and a lil history on me, i had a build CA19DET in a S13 Silvia (RHD) with all the tircks (Haltech, JE forgies, Crower rods, Tomei 260* ProCams, gears & springs, T3/T04E, 550's, FMIC kit, stagte 4 clutch, i.6 HKS HG, Blitz Nur Spec, and all the other usual parts) http://www.bezman.com/ca19det/ca19.WMV - short vid of start up, no running vids sorry... Lots of pics... some below well it ran very good - dynoed 260whp at 10-12psi i ran as much as 17 on this set up..., 14's on street radials at 10psi nver really got to do any runs at higher boost as out track has been closed to illegal/private test & tune sundays... well time went on.... and after a hard run i had detonation caused by an injector shorting in #3 and the cam belt jumped a tooth on the exhaust cam, pulled the head to find #2 & #3 especially had signs of detoantion on the piston tops... dropped tha pan to see an oil squirter had broken off #1.. hmmmm.. oh well, damage to the head & pistons, block slightly... $$$$ - sell everything and clear my head. for now i'll jsut put a stock CA18DET in there for now from the engines i have laying around, sell all the other CA parts, keep some and start a new project... pics of my past engine during the build http://www.bezman.com/ca19det/ca19_2.jpg after http://www.bezman.com/CA19_002.jpg i have allot more pics if wanted and you can see the similarity between the CA & RB and how it would fit in there. its been done and covered a million times.. an RB25 would be nice but they are expensive around here (about 3 times the cost of a RB20) and hard to find, RB20's are all over the place, so spares are easy to get and a spare motor or two would be cheap
