{"product_id":"gtr-r35-kt-1400-long-block","title":"GTR R35 KT 1400HP Long block 3.8L (Reused block \/ heads)","description":"\u003cp\u003eThis KT1400 street GTR R35 3.8L long block is precision assembled to the highest tolerances. Each one of our engines comes with a full blueprint and a list of all parts and measurements that went into the build. This long block REQUIRES a core in good condition.\u003c\/p\u003e\n\u003cp\u003eWhen you purchase a long block engine package from us, you can rest assured that you are getting the following services with it:\u003c\/p\u003e\n\u003ch4\u003eAll crank journals precision measured and matched to the corresponding bearing.\u003c\/h4\u003e\n\u003cp\u003eWe measure each journal and then use only individual bearings that match each cylinder. While most builders use a standard or extra clearance rod and main bearing set where all the bearings are the same...we refuse to do so since R35 street engines require special attention to oil clearances. Instead we use individual race bearings that are graded, matched to each cylinder and then recorded in the blueprint. While being more expensive, it ensures that each crankshaft main and rod journal has the same oil clearance and the same load bearing tolerance under high boost. This is especially beneficial for street engines that must endure long drives and high oil temperatures before even making a pass.\u003c\/p\u003e\n\u003ch4\u003ePrecision balanced rotating assembly\u003c\/h4\u003e\n\u003cp\u003eWe balance our rotating assembly and add Mallory weight as required to obtain a near zero-balance. A complete balance sheet is provided with each engine to ensure that the rotating assembly is vibration free. This engine package is rated to 9000rpms safely for street use.\u003c\/p\u003e\n\u003ch4\u003eStretched rod bolts\u003c\/h4\u003e\n\u003cp\u003eWe don't just torque our connecting rods and hope for the best! Instead we use the correct method of stretching each of the rod bolts to the manufacturer's recommended value, thus ensuring that each bolt has the exact same clamping force and is not affected by friction or other factors that come with using torque to tighten rod bolts.\u003c\/p\u003e\n\u003ch4\u003ePrecision-cut bearings\u003c\/h4\u003e\n\u003cp\u003eA little-known fact is that the bearings in the R35 have to be machined (narrowed) when using a billet crankshaft. This is necessary because billet crankshafts feature extra material around the journals and this creates a fillet at the ends that does not sit flat with the bearings. We have special tools and a machining process that ensures that every bearing is machined precisely to clear this fillet without damaging the bearing coated surface. This is a critical process since a bearing that is not narrow enough will dig into the crankshaft fillets and one that is too narrow will have poor load capacity.\u003c\/p\u003e\n\u003ch4\u003ePrecision line honing\u003c\/h4\u003e\n\u003cp\u003eAn often overlooked step when upgrading a VR38 block with ARP main studs is the line honing process. The ARP main studs have a stronger clamping force and thus distort the factory round shape of the main bores and this requires a correction using CNC machines that can hone back to a round shape without taking out too much material.\u003c\/p\u003e\n\u003cp\u003eWe also have proprietary-made CNC deck plates that we use when line honing the block to simulate the distortion caused by the head bolts.\u003c\/p\u003e\n\u003ch4\u003eFactory correct sealer and gaskets\u003c\/h4\u003e\n\u003cp\u003eWe only use the recommended sealer and gaskets in our engine builds. This is a critical step in the build of a VR38 since most components are mated using sealer and orings. The use of the correct sealant, applied in the right quantities ensures a leak-free engine.\u003c\/p\u003e\n\u003ch4\u003eFine-tuned valve lash settings\u003c\/h4\u003e\n\u003cp\u003eThis is perhaps the most important step in a GTR build and also the most overlooked. Ensuring each valve has the correct lash is critical in order to prevent problems in tuning later on, rough idle, loss of power and other byproducts that come from valves that have different lash settings. Since the GTR uses a solid cam follower, the process is tedious and requires a large stock of different sized cam buckets. Here at Karel Tuning we carry every size in stock and this allows us to finish lashing each valve to within 0.001\" every time.\u003c\/p\u003e\n\u003ch4\u003eAll new timing components\u003c\/h4\u003e\n\u003cp\u003eYou can rest assured that your new build comes with all new timing components as stated in our build list. This is a critical step to ensure reliability and longevity of the new build.\u003c\/p\u003e\n\u003cp\u003eThis package includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eACL Race coated rod bearings (Graded individually for each rod)\u003c\/li\u003e\n\u003cli\u003eACL Race coated main bearings (Graded individually for each main)\u003c\/li\u003e\n\u003cli\u003eACL thrust bearing\u003c\/li\u003e\n\u003cli\u003eManley 300M Turbo Tuff connecting rods\u003c\/li\u003e\n\u003cli\u003eManley extreme duty pistons and pins (Graded individually for each bore)\u003c\/li\u003e\n\u003cli\u003eARP main studs\u003c\/li\u003e\n\u003cli\u003eARP 625 head studs\u003c\/li\u003e\n\u003cli\u003eOEM complete gasket set\u003c\/li\u003e\n\u003cli\u003eGSC upgrade valve seals\u003c\/li\u003e\n\u003cli\u003eGSC Conical valve springs and titanium retainers\u003c\/li\u003e\n\u003cli\u003eAll New timing chain tensioners\u003c\/li\u003e\n\u003cli\u003eAll new timing chains\u003c\/li\u003e\n\u003cli\u003eNew oil pump chain\u003c\/li\u003e\n\u003cli\u003eBillet oil pan\u003c\/li\u003e\n\u003cli\u003eATI harmonic balancer\u003c\/li\u003e\n\u003cli\u003eTomei 274 Pro Cams\u003c\/li\u003e\n\u003cli\u003eManley race intake and exhaust valves\u003c\/li\u003e\n\u003cli\u003eNew cam timing sprockets\u003c\/li\u003e\n\u003cli\u003eBalance GTR VR38 Split pin Crankshaft Internally\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBlueprint and measurement of all components\u003c\/li\u003e\n\u003cli\u003eBuild sheet\u003c\/li\u003e\n\u003cli\u003eGTR VR38  CNC multi angle seat cut on OHC 24V Cylinder Head  with new Bronze alloy seats, Blend seats\u003c\/li\u003e\n\u003cli\u003eGTR VR38 File-fit piston rings\u003c\/li\u003e\n\u003cli\u003eGTR R35 VR38 Line hone\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Remove silicone from timing covers, girdle, block, and upper oil pan\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Set Valve Tip Height\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Set valve lash VR38 (to within 0.001 using cam buckets)\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Set valve lash VR38 (to within 0.005)\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Set valve spring height (Per spring)\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Resurface aluminum cylinder heads (both), Match chambers\u003c\/li\u003e\n\u003cli\u003eGTR VR38 Jet wash cylinder heads and engine components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis item ships via freight or is available for pickup.
