: GTI-R Or Not To GTI-R? That Is My Question...... sinistersntra91 10-04-2002, 11:12 AM I have a B13 SE-R and I want a GTI-R SR20DET but I was wandering who has em and are they worth it or should I go with the BB SR20DET? What are the ups and downs to them? Does anybody got specs or 1/4 mile times? And most of all should I go with a GTI-R or go with the BB? ITR_KILLR 10-04-2002, 01:06 PM well, if you plan on upgrading after the swap I would go with the BB, the ups of the GTIR are: T28, (vs. T25 on BB), beefier rods, ind. TB's, stronger bolts, studs, etc. It is easier to use the BB, in my opinion. GTIR parts generally will not swap out with USDM parts, so if you break something, it will be a headache getting a new one. even if you planned on keeping the GTIR pretty stock, I would consider buying a BB motor w/o the tubo or manifold, and just buying the GTIR mani, and turbo. xDennis 10-10-2002, 03:24 AM this is from: http://sr20det.nismo.org/srtech.htm Here are the differences between the DET and the DE: The DET has oil squirter piston coolers The DET has a bigger oil pump. The DET has a different front pulley. The DET has lower compression pistons (8.3:1 vs 9.5:1). The DET has bigger injectors. The DET has direct ignition. The DET has a variable intake cam, runs retarded at idle, advanced mid range and retarded top end. The DET has mechanical shim in bucket type lifters with a slightly bigger in duration exhaust cam. The GTi-R DET has individual Throttle body injection. The GTi-R DET has stronger main cap bolts. The GTi-R DET has beefier rods. Hope this Help, also the GTi-R has a T28, and the DET has a T25 sinistersntra91 10-10-2002, 12:11 PM thanks alot eric96ser 10-10-2002, 01:43 PM Originally posted by xTurbo Classicx this is from: http://sr20det.nismo.org/srtech.htm Here are the differences between the DET and the DE: The DET has oil squirter piston coolers The DET has a bigger oil pump.

Hope this Help, also the GTi-R has a T28, and the DET has a T25 wrong the BB/Avenir DET is about 95% the same as a DE. The only differnences are: 8.5:1 vs 9.5:1 piston oil squiters bigger injectors you were quoting RWD DET parts. The AWD DET is different. Please check your facts before you state them. sinistersntra91 10-10-2002, 02:20 PM Yeah I wondered if there was a difference SE-R-2-Go 10-10-2002, 06:12 PM Originally posted by eric96ser wrong the BB/Avenir DET is about 95% the same as a DE.

LONEWOLF 10-11-2002, 11:04 AM ISN'T THE OIL PUMP BIGGER ON A BB DET eric96ser 10-11-2002, 12:19 PM Originally posted by LONEWOLF ISN'T THE OIL PUMP BIGGER ON A BB DET http://www.manifestation.org/~ill/images/funny/capslock.gif NO xDennis 10-11-2002, 01:24 PM Originally posted by eric96ser wrong the BB/Avenir DET is about 95% the same as a DE.

Sorry, the last few on the list are for the RWD DET... charlie2020 10-11-2002, 02:09 PM GTi-R 8:3:1 T28 Bigger Oil Pump Bigger Water Pump Bigger Oil Cooler Bigger Injectors 444cc/min Mechanical Valvetrain/Different Cams Bigger Rods Different ITM design Bluebird/Avenir 8:5:1 T-25 Same oil pump as SR20DE Same power steering pump as SR20DE Same water pump as SR20DE Same alternator as SR20DE Smaller Oil Cooler than GTi-R/Some BBs don't have this Smaller Injectors 370cc/min than GTi-R Hydrualic Valvetrain same as SR20DE/Same type of Cams Bigger exhaust valves and sodium filled than SR20DE by 1mm Same Rods and bearing as the SR20DE Smaller but deeper oil pan than SR20DE no chance of oil starvation oil pick up strainer is submerged more than the SR20DE Same ITM as high port SR20DE (99.9%same) | ||
