On 95 and later cars with an internal coil, MSD makes an external coil conversion kit for Hondas that also works on our cars. Surprisingly I can feel a larger SOTP difference with the 4 piece set. Their testing showed that Motul was excellent. The JWT cams have at least twice the potential power gain as the alternatives and whether you think its worth the money is up to engine performance module you as a consumer so dont waste their time on this point. Stones can give a good valve job but the stones must be dressed frequently engine performance module and dial indicators must be used to insure that the seating surface remains concentric. I am not sure of its root cause. These plugs will absolutely not work engine performance module for long in high compression, high rpm, boosted or NOS applications. Forged pistons can also handle the strain of high boost and Nitrous. The main advantage of the DPR head is Dans combustion chamber work. George Roffe, Mike Palhs and Ben Benavides have all or some of these latest mods in their motors and we eagerly await engine performance module dyno results. The new generation Stillen and Hotshot headers do not seem to make this noise. That is 4 ten thousandths of engine Genuine John Deere Oem Brake performance module an inch! We will be posting the results of engine performance module this manifold as Kurt get around to it. I have installed engine performance module both headers and the fit is very good on either. This is important for correct hydraulic lash adjuster function and correct valve train geometry. A five engine performance module angle valve job uses two extra cuts to make the transition even smoother. Get some setup, either from the aftermarket or whatever home-made concoction you can come up with, to extend your intake pipe and get your filter away from the heat of the engine but not too engine performance module close to the ground and you should be in good shape. If you are running NOS with someone elses kit, you will have to retard the spark a little under NOS operation. As I have stated before, a JWT ECU is mandatory with 11:1 to prevent engine-destroying detonation regardless of piston type. To my knowledge, the best oil filters are genuine Nissan. JWT is also the only company to my knowledge at this time that can do reliable programming on Post 1995 OBD-II ECUs. This raises the CR on stock pistons form 9. As a non oil related note, Redline Water Wetter is legitimate and really has a reduction of water temp by about 20 degrees F, good stuff. I would not recommend a low silicon piston for street use no matter what. The generally cheesy construction won’t last long either. Unorthodox Racing Underdrive Pulleys Big Bore Throttle Bodies and MAFs engine performance module Spark plugs and Ignition systems Reader’s Contributions Some additional information that people might be interested in: Mike’s Mike’s Mike’s Mike’s Mike’s Engine Block Preparation Guidelines Searl’s Turbo Project Mike’s Turbo Theory Please Contribute! RS Akimoto supposedly make an intake for the Classic but I have never seen one. JUN I only have anecdotal information on these cams. Dan could have made me some bigger valves but I did not engine performance module want to pay for that! In my opinion the best spark plugs for the SR20DE and DET are the engine performance module stock Genuine Nissan NGK platinum plugs. Cam Shafts So far, the JWT cams are about the only ones that work well on the market. Dual path, straight through, perforated core mufflers like the Edelbrock should work well also, although engine performance module I have no direct experience with them.
They are engine performance module also the only tuner in this country who has pushed the limit of SR20 (and Nissan in general) development. The new product is even better. Swirl polishing engine performance module is polishing putting a hurricane looking pattern on the face of the valve. I tried to make the car overheat in bumper to bumper traffic on an 80-degree day, plus high speed cruising and free revving the motor to 7000 rpm for a few minutes. I use Swain tech gold thermal barrier coating on my pistons. NGK Platinum Spark Plugs for a comparison of the two. To eliminate this Nissan went to the current low port design with its short intake port and close coupled injectors. You dont want to remove so much material that the crank dimensions change, just reduce the RMS of the surface by knocking off the peaks of the machining marks. Justin engine performance module Choi Writes: I had a custom cold air intake made for my 92 Nissan SE-R a while ago and got my hands on a Techtom to test it out. Both the crank and rods are subjected to John Deere Hyd Quick Connect a severe shotpeening from the factory. If you are going to push the edge with turbo boost, nitrous or are going to do some real racing, forged pistons are the way to go. You can get the Nissan oil filters at Courtesy Nissan for about $5 for the 200SX and $4 for the Classic Headers Headers are probably the biggest bang for the buck item in the modification list.
Be sure to put a slight chamfer on the pin bushing after you are done. The new Hotshot header solves this problem with the addition of a engine performance module copper gasket that is just about John Deere Gt235 blow-out proof. JWT can also custom program the ECU for high compression and turbocharged applications for a reasonable fee. Gutting the cat will cause a MIL light on post ’95 SE-Rs which is to be avoided come registration time. I dont have any experience with these. I plugged in a CONSULT to test for charging function and overheating. Boring and honing should engine performance module be done on a Sunnan CK10 machine. This turbulence makes the port virtually a engine performance module little smaller at low flow velocities. JWT can get Crower rods. 020″ to prevent it. Forged pistons can be made thinner and lighter due to Genuine John Deere Oem their superior strength. High engine performance module Power Ignition I havent run across a SE-R that has needed this yet but I suppose that over a 100 shot of nos or 18 psi of boost might need a high power ignition. Opposing opinions to the editors are welcome but remember please present your arguments in a quantitative and professional fashion engine performance module if you want them posted. Dan also reshaped the valves going way beyond the customary 30 degree back cut. I dont think this cam set could pass a smog test and they would most likely freak out the OBD-II system although I have never tested either. My engine is getting close to the point where it can top out the stock ECU but not quite yet. A hotter plug has a longer path engine performance module and dissipates heat more slowly. Increasing quench does raise the compression ratio, so if engine performance module you are doing pistons and stuff, this must be considered. Ed Wolf and Kurt Sussman run these cams in their 200SXs. This means no real high boost levels (much above engine performance module 14 psi) or huge nitrous hits (certainly not more than 100 hp). The first is the SR20DET “European” grind exhaust cam that Stillen and Nissan engine performance module Motorsports carries. I also tested engine performance module using a big 80mm MAF from a late model Maxima using a custom programmed JWT ECU. On an esoteric note, under racing conditions the SR20, especially in an NX, can be subject to thermal runaway. Comp Cams Now a major maker of domestic car cams tries to get involved with the import market. These high power ignitions will not give you much more power but they will eliminate frustrating misfire and help starting and low speed driveabilty. The HKS (cat-back, of course) lowered engine performance module 1 4-mile time by a tenth; increased trap speed by. If your engine is stock or if you are limiting yourself to bolt-ons, limit your pipe diameter to no more than 2″ or you will lose some bottom end with no applicable gain on top. For this reason the main caps should also be bolted on and torqued when the block is being machined. We have seen gains of 1-3 hp on a typical SE-R engine performance module although some SE-Rs have gained as much as 8 wheel Genuine John Deere Oem Plate hp. The Walker and the Magnaflow mufflers are real loud by themselves and require a pre-silencer. For best performance on engine performance module a stock engine, put in 92 octane and dial in between 17 to 19 degrees. 005″ increments engine performance module until the misfire stops. These ignitions are very powerful, capable of firing the spark plugs for over 30 degrees of crank rotation. More displacement can mask some of the bad characteristics of big camshafts like lack of low end power and lumpy idle.
Cast pistons are made engine performance module by pouring molten aluminum into a mold. A genuine Nissan cast piston is dimensionally more stable than a forged piston and can run extremely tight piston to wall clearances, as little as 0.
In my opinion the AEBS or the Hotshot are the best headers for the SR20 currently on the market. Poly Moly engine performance module can help tame the clatter of forged pistons. If you are building a hot street SR20, I recommend leaving the rods alone. Some listmembers have recently dyno tested these plugs on stockish engines and have found them to be OK. Look for a perforated core. The rod bolts are a beefy 9mm. One engine performance module famous Honda tuner (THE MOST FAMOUS Honda tuner) came up with some cams for the SR20. The HKS system is supposed to engine performance module be quiet and the Borla, Ive heard, is loud. The JWT gears are safer by being impossible to slip or vibrate apart and are cheap.
Use a puller or back up the bolts with a peice of thick metal to prevent damaging the cover. This included some used plugs that were at least 20k miles old. It is impossible to spot by just looking at the car. This throttle body is 64mm vs the stock 60mm. For a classic 91-92 SE-R or NX you only use the exhaust cam as the intake cam has the same duration as the DET cam. Both are about equally easy to use. Here is some more info on Exhaust systems Air Intakes The most common are the JWT POP Charger (POP stands for Performance Optimized Program) and the which are almost identical. JWT has a 50 shot program for 11:1 available. I tried about 25 different combinations of advancing, retarding, lobe separation angle spreading and tightening with no gains worth keeping over the stock location. Generally porting your head will cause some loss engine performance module of bottom end power. Teflon is also a heat insulator. From my personal experience on many different Hondas and Nissans, I can tell you without a doubt that the cold air setups offer more horsepower than standard K&N and intake stack setups on most cars. When hp levels are quoted we are talking the maximum amount of power gained by the part in SOME point of the powerband, not necessarily the peak hp gained. This causes the port engine performance module walls to get wetted with fuel. Poly Moly also tightens your piston to wall clearance by 0. The ceramic coating may aid catalytic light off under cold start conditions which is helpful engine performance module for OBD-II cars (1995 and later). This proves that clean does Genuine John Deere Oem Wear Ring not mean slow. Just be sure to cut the primary conductor from the stock coil and engine performance module fill the resulting hole in the distributor cap up with silicone or some of the extra power from your new coil will be wasted. The disadvantages of a forged piston are that it must run a larger piston to wall clearance than a cast piston. This is surprising as 4-1 designs usually favor the top end of the powerband. My DPR head is a marvel of detail. Even through the Maxima unit is nearly 45mm engine performance module larger than the tiny stock MAF, I did not gain any power except for about 2-3 below 4000 rpm! I have screwed up 3 engine performance module SR20s myself but that was the result of not watching the temperature gauge while racing IMSA and SCCA. That engine idled like a fully built motor and I was surprised that we were never protested. Try to avoid the typical muffler shop crush bends. Although it felt like it was giving a lot more power in my SOTP evaluation, on the Dyno no power increase at all was registered just as I had previously predicted. Dan engine performance module has also developed a new valve spring set and new titanium retainers as well as 1 mm oversize stainless valves. We suggest that Unorthodox add marks in 5-degree increments to the pulley instead of just a TDC mark. I recommend running bearing clearances in the middle of factory spec on a typical street motor. When used with the hydraulic lash adjusters in the SR20DE, these flanks keep the valve open a few thousands of an inch for about 10-20 extra degrees of crank rotation. This shops work could not be all bad because of their track record, but I have yet to see a good off-the-shelf head from them. NGK V plugs These work fine, just change them frequently. Talk engine performance module about shrouding!
After running the car, my SOTP estimate of power gain was small, about 1-2 hp. I do not recommend this to anyone who lives where it gets below freezing but for my native sunny California it is OK. Not only engine performance module is it the cheapest but it works the best. When you mill things the cam timing retards and you can use adjustable gears to correct it. Be sure to oil them with K&N oil after cleaning in detergent and water. S&S The S&S header is a small diameter, long length primary tube 4-1 header. I myself engine performance module do not have any experience with these. I do have plenty of good personnel Genuine John Deere Oem Draft experience with shotpeening solving many parts breakage problems. We tried Extrude Honing the manifold on project SE-R. When building a killer motor it is a good idea to replace the main engine performance module cap bolts with the ones found in the SR20DET. These racing rods do not have the oil squirter hole in them which could engine performance module result in slightly shorter life of rings and pistons. The Techtom allows testing of the car engine performance module out on the road in real-world conditions. To run 11:1on pump gas requires engine performance module a special program from JWT. As aluminum starts to lose strength above 350 degrees, piston coolers can help quiet a bit. Although engine performance module it is pretty inexpensive there are a few problems. Nissan Motorsports stocks these. It wont hurt to do these traditional race prep steps but it is probably not worth the effort on the SR20. If you want to buy another brand of ECU, ask these questions. I have no direct experience with the GReddy unit but it appears to be made of a fine foam which could filter better I suppose. You can engine performance module buy mandrel bends from Kinsler, Burns stainless, or Bassani. The VG30 in my Pathfinder will barely run with engine performance module these plugs. More ignition retard and richer fuel mixture are appropriate here. I do not have any personal experience with the well-publicized-by-Turbo-magazine, Metalax engine performance module treatment process but have heard good things about them. We want to keep this as a no-BS, factual, hard core tips section. To exploit these cams you will need high compression and headwork. This hole sprays oil on the thrust side of the cylinder helping with lubrication and keeping the engine quiet. The hydraulic lash adjusters on the SR20 engine do engine performance module not like thick oil. Chuck Nibbanas super trick engine also mysteriously engine performance module disassembled itself but that might have been because of improper clearancing.
