The right way. Basically a block and head, just a general, cost and planing for this build. Would love to get the 89 sx, back from the dead. Hello Gerald, Please check your email for additional information. Hi I am going through a huge mess with a sr I purchased has cylinder score and idk if it is savable, the head was missing can caps and cams , so much stuff messed up or missing should I cut my losses or go for a new cylinder head and machine work, any information would help. Hello Kyle, We just sent you an email with a request for additional information.
This motor was built for reliable hp range, although it would be capable of more. Hello, Your question is somewhat vague and it is hard to provide a definitely answer. There are a lot of undisclosed variables we will have to discuss. These days you can daily drive on cc injectors and E85 like its an OEM car with a proper tune, of course.
Your power requirements and turbo size will mainly dictate how drivable the car will be. We have customer daily driving GTXR cars. Hello Ben, Engine bearing clearances will depend on how you will be using the engine street performance, drag racing, endurance racing , engine RPM, oil pump volume, oil viscosity, and oil temperature.
Higher viscosity oils will require larger bearing clearances that lower viscosity oils. Do you guys have rebuilt sr20det motor for sale or do you just do services. Im planing on buying a motor for my Datsun roadster. Hello David, We do have block and cylinder head cores in stock that we can use for your project. Please check your email for a message from us so we can discuss your rebuild options. Hello Wade, Thank you for the interest. Please check your email for additional information request.
We can discuss your particular needs and design the engine accordingly as a package with a properly matched turbocharger, injectors, and ECU. I would like to rebuild an SR20DET engine and get it up to horsepower reliably and I would like a price on the build. Please check your email for an additional information request. Describe the current condition of your SR20 engine, your requirements, both in power and type of use, i.
This will help me design your project and estimate build costs. Would you be able to email me some contact information? I am looking at either sending you this motor, or purchasing one from you which would make a reliable, street-able, WHP and would be fun for daily use as well as track no drifting.
Hello Mario, Please check your email for additional information request so we can discuss your project. Regards, Pavel Osovets. I have a s13 redtop sr20 that recently started knocking really badly. This is my daily that I thrash on from time to time, so it needs to be strong. Please check your email so we can discuss your exact engine condition and the type of rebuild service that best suits your needs.

William Hernandez. We sent you an email. Could you also send me an email with a pricing breakdown for a similar build. Hello Doug, We sent you an email with additional information. Hello, We sent you an email with details. Michael K. Could you send me a pricing email as well?
Do you have the Dyno information? The long-block looked good upon initial inspection and was sold to me with a S15 6-speed transmission for a rock bottom price. Upon purchasing the S14 long block, I began immediately tearing down the engine. It was during that time when I noticed a major red flag. The previous owner who sold my friend the engine had used silicone gasket sealant to seal the head gasket.
The biggest fear was that silicone was used as a band aid to remedy either a warped head or damaged block. Regardless of the situation, I pressed on and stripped the block bare, knowing that this issue would have to be thoroughly inspected at the machine shop. I also found the crankshaft had some scratches and scoring on the main and rod journals that would also need to be corrected and polished prior to its return to service.
Luckily, the internals of the SR20VE engine showed no signs of destruction, as all the parts appeared to be in pristine condition. Now this is where things get interesting for the build. Call it blasphemous or just plain awesome, but this is truly a Frankenstein build that is different from a typical SRVE swap. The H22 rods measured in at 5. This sets the engine up with a rod-to-stroke ratio of 1. Comparing both Nissan and Honda rods reveals both the big end and small ends are identical in size.
The only difference was the rod width which was easily addressed through machining the big ends of the rods to clear the SR20DET crankshaft journals. This gives the engine a better rod ratio without having to shelling out large amounts of cash for a custom set of connecting rods. In theory, the longer connecting rods should net the engine a wider powerband, while the lighter piston and rod combination will offer improved engine response.
In general, both pistons will perform their function in any application if designed properly. However, the asymmetrical piston design has a significant advantage over traditional round designs, including reduced skirt width on the minor thrust side. This helps to minimize piston contact with the cylinder wall, which causes friction and power loss.
The sum of these three design elements becomes a significant weight reduction. For this engine build, I chose an 87 mm piston with an The pistons were also designed specifically for use with the VE cylinder heads, and machined with the requested valve relief depth to clear the soon-to-be-installed Kelford camshafts. Each of these features will help engine performance in some way.
Reputable machine shops will go to great lengths when boring and honing an engine block in order to simulate the same internal stresses the block is under while the engine is operating. These included the flange interfering with the RWD conversion water neck adapter, bore spacing, which was slightly off, and the inability to bolt on the TWM setup towards the front of the cylinder head.
Due to these numerous setbacks, the adapter flange setup was ultimately scrapped, which forced us to retreat back to the drawing board. Once again, I turned to Designcraft for assistance in machining the runners to equal lengths. Castillo machined an adapter so he could cut each throttle body on the lathe.
He also cut the cast vacuum port so all four could be connected with a silicone vacuum line. I consider Gary the Filipino version of MacGyver as he can take random parts and make them into a functional item. He used longer aluminum tubes, then cut and shaped them before they were welded between the flange and ITBs. The tubes were angled the same as the cylinder head port design to deliver a straight shot into the ports.
Silicone couplers were used to secure the ITBs to the flange as a temporary setup, as we plan to test various runner lengths on the dyno to see what gains or losses can be achieved.
The end result was pretty awesome as we had a fully functional setup that bolted on—or so we thought, until it came time to install the fuel rail. Unfortunately, the spacing of the injector holes on the rail along with its angle caused the injectors to sit at an awkward position with the possibility of leaking.
After multiple attempts to properly seat the injectors, we decided to scrap the new fuel rail and return back to the original TWM rails.
In the end, things worked out perfectly as we were able to retain the intended TWM injector location while making use of the fuel rail and modifying it for a dual feed setup.
A custom throttle cable was sourced from a hot rod and put into place and the ITBs were finally on and done. Comparing the two, the EV14 injectors offer superior low pulse width control which can be noticeable with things such as idle and low rpm driving.
These injectors utilize a multi-orifice tip for improved atomization. I went for this after finding sustained high revs with a stock breather set up bar a catch can vented to atmos resulted in the crank case pressurising as keeping all the oil in the head, which eventually would blow out the breather pipes.
