RB24S not made for the Jap domestic market  fitted to left hand drive Nissan Cefiros exported from Japan made from RB30E head, RB25DE/DET block, RB20DE/DET crank with 34 mm height pistons... used carburettors instead of the ECCS fuel injection system. RB25DE/DET (same stroke as the RB20DE/DET) almost the same displacement as the RB25DE/DET RB26DETT N1 RB26DETT N1 a moded version of the RB26DETT made by Nismo for Group A and Group N motorsports they found that the standard RB26DETT was to hard to work on during a race the crank shaft it almost perfict when its balenced due to the higher RPMs 7-8k (made better) use Garrett T25 turbochargers but changed thru the 3 generations of the RB26DETT N1 engine (R32, R33, and R34). The R32, and R33 versions used Journal Bearing T25 Turbochargers the R34 RB26DETT N1 engine used Garrett GT25 turbo chargers (Ball Bearing). The biggest difference between the turbochargers in the N1 engine and the RB26DETT engine, is that the Turbine Wheels in the turbocharger are made from Steel, rather than the Ceramic used for the RB26DETT turbochargers (unstable @ high turbine RPMs) the N1 is rumored to make 1900bhp when tuned right The RB26DETT N1 Engine Block uses an 86 mm bore but can be bored up to either 87 mm or 88 mm. The N1 block is stamped with an identification mark of 24U the RB26DETT block is marked with 05U. RB26DETT Z2 prety much a RB26DETT N1 on crack used in the nismo GTR Z-tune RB30 made for the use in Skylines, Patrols and Cefiros, bought by Holden because the Holden 202 (3.3 L) powering the Holden Commodore could no longer pass emissions requirements, with all new cars required to run on unleaded petrol by 1986, a quick replacement was needed. Nissan sold the RB30E to Holden for the VL Commodore The RB30E in the VL suffered from cylinder head cracking due to the radiator being fitted lower in the engine bay, causing air locks in the cylinder head. This was not as severe in R31 Skyline as the radiator is mounted higher. The engine was very reliable apart from this issue. The RB30S was found in some Middle Eastern R31 Skylines and in some Nissan Patrols. The RB30E was found in R31 Skylines and VL Commodores in Australia as well as in South African R31 Skylines RB30DE rare  engines used in the Tommy Kaira M30 based on the R31 Skyline GTS-R. A modified RB20DE head was bolted on to the RB30E blockRB30DET Nissan did not produce this engine, but it refers to a turbocharged engine featuring an RB30E block with a twin-cam head conversion. Common hybrid in Australasia (referred to as the RB25/30 or RB26/30) using a RB30E bottom end mated to a RB25DE,RB25DET or RB26DETT cylinder head and turbo (RB20DE and DET heads are not used as the bores are different in size; RB30 86.0 mm RB20 78.0 mm but were originally modified and used on the tommy kaira Rb30de as the RB25 engine did not exist). The RB25DE cylinder head from the A31 Cefiro C33 Laurel or R32 skyline (aka: Non VCT)can be used, and fits perfectly on (although better valve springs are recommended, Gtr valve springs are a decent upgrade). The RB25DET (from the R33 Skyline or C34 Laurel or Stagea) head is also used, however an external oil feed must be fabricated for the variable cam timing (VCT) on the RB25DET, and the galleries at the front of the engine do not line up. The variable cam timing may be disconnected altogether.Also it is wise to change the oil restrictor's in the block to 1.5mm and get a full face oil pump drive collar machined onto the crank(solves it shattering at high RPM) with the use of a twin cam oil pump. The fitment of a twin cam head from any of these engines onto a standard compression RB30E bottom end gives an ideal compression ratio for a mild to moderately modified street turbo engine around 8.2:1, (but always check your compression when building this engine as it may vary), making the conversion popular amongst those who would otherwise convert their RB30E to a high compression RB30ET using original ET bolt on externals. Although it has a larger displacement than the RB26DETT, maximum possible horsepower is less, as the RB30 block lacks the RB26 block's internal cast-in bracing, and consequently cannot rev as high due to harmonic issues at ~7500 rpm. To compensate, the RB30DET produces more torque at lower revs due to its longer stroke. However they have been known to reach engine speeds up to 11,000 rpm with a lot of balancing and the use of the RB26 head with solid lifters. Power of the RB30det in this form can far exceed that of an RB26dett, RB30DET's are usually only found in rwd cars as it's a lot easier to install, with the 4wd setup in the GTR or GTS4 an adapter plate has to be made to fit the 4wd sump as its bolt pattern is different to the RB30, as there is a adapter plate between the sump it sits off on the gearbox bolt holes, they will have to be modified to fit RB-X GT2 The RB-X GT2 (also called REINIK) is an engine just made for the Nismo 400R. The difference between this engine and a RB26DETT is that the engine is bored and stroked (87.0 × 77.7 mm) which results in 2771 cc. Engine produces 400 PS (331 kW or 443 HP) at 6800 rpm and 47.8 kgf·m (469 N·m or 347 lbf·ft) at 4400 rpm. This engine was manufactured with a reinforced cylinder block and cylinder head, metal head gasket, pistons with cooling channels, forged crank shaft, forged connecting rods, N1 turbine with reinforced actuator, high flow air cleaner, stainless down pipe, and low air resistance sport catalyzer, most of which were not offered for the RB26DETT. ok the last two were from wiki... dnt hate i knew alot from the others  EDIT some info found at wikipidea nissan model parts book Edited by Patrick, Mar 5 2010, 09:33 AM.
