Time for a new engine - 1995 Del Sol Si
Great looking forum, looks to be full of excellent info.
A brief mention of our current situation. We have a 1995 Del Sol Si (Sohc VTEC I believe). The engine is pretty much ready to go any day now. The rest of the car is excellent condition. That being said I would like to keep the car and use it for open track days at a neighboring track. Naturally a new engin would be in the cards. Rather that getting a decent used stock Si engine I would like to go with the VTEC Del Sol engine. I have found a number of decent posts with info, however, before I get to far along the road with this project. I want to make sure I am barking up the right tree. I found the following which looks to be the direction I want to go.
Essentially I would be going from Del Sol Si to Del Sol VTEC so the above info looks to suit my situation. I never really entertained that thought of going to a power plant from another car model such as an Integra or even a larger motor like the 1.8. I was hoping to make this as painless as possible. This project will be my first engine swap so I am really hoping to get all my "ducks in a row" before I start. I appreciate any assistance, help, or tips so I can get it right the first time. Once again, great forum.

I have found a number of decent posts with info, however, before I get to far along the road with this project. I want to make sure I am barking up the right tree.

92-95 EG and Del Sol with 94-2000 GS-R B18C(including Integra Type R) & 93-97 Del Sol Vtec & 99-00 Si B16a2
Transmission: These Engines come with Hydraulic clutch transmissions including Japanese or American market Y21, Y80, S80, AND S4C. Japanese or American market S1, J1, A1, Y1 or YS1 cable clutch transmission with Hasport cable conversion kit part # M92-CC can be used.
Mounts: A combination of stock and integra mounts can be used if a hydraulic B- series tranny is used. on some 96 and up engines you may need to change the bracket under the timing belt and on the rear of the engine for ones of the appropriate year.
ECU: Use ecu that came with the Engine with proper wiring modifications. For those who do not wish to use OBDII ecu's. For the B16a2 Si motor use the JDM P30 Ecu. Other wise you may use a Chipped P28 with the Proper Programing.
Electrical Differences: B18C1 add air intake Bypass wiring. Cx and Vx need to conver to 4 wire o2 sensor. Non Vtec models need to be wired for Vtec solenoid and Vtec Pressure. All models Modify stock harness to fit. add knock sensor if you are not using a Chipped p28 ecu. Hasport Harness for B18C1(GSRmotor) part #EGDX-GSR
Axles: 90-93 integra axles, 94-up integra axles, 94-97 Del Sol Vtec axles, or 99-00 Civic Si Axles. Note the intermediate shaft seal in the left side of transmission is different for 90-93 Integra Axles. Depending on Axle transmission Combo, It may have to be changed. Hasport Part#: EGBAXCMP
Shift Linkage: 94-up Integra linkage for Civics. 94-97 Del Sol Vtec linkage for Del Sol
Upper Radiator Hose: For Engines using b16a or Type R Head use 94-97 Del Sol Vtec Hose. For Engines with GSR head use 94-up GSR hose
Lower Radiator Hose: 94 Delsol Vtec
Throttle Cable: For Engines with B16a head, use 94 Del Sol Vtec. For Engines with GSR (B18C1) head use 94 GSR. For Engines with Type R head Use 98 Type R
Clutch Hydraulics: Stock
Air Conditioning: 94-95 Del Sol Vtec A/C Bracket
Special Instructions: Using OBDII ECU involves wiring modifications. Generally if the ECU you choose does not use the same plugs as the stock ECU, an adapter harness will cut down on alot of potential problems.
Special Considerations: US motors are smog legal as long as the motor is from the same year or later. Japanese type R motors are very potent and wiring is relatively easy with ecu adapter harness. The B Series engine swaps into these year vehicles are by far the easiest. there are honda mounts available to bolt those engines directly in and the wiring is by far the simplest. The majority of people opt to put in a B18C, B18B, or 94-95 Del Sol B16a and those bolt in directly using Del Sol Vtec Mounts. the Del Sol mounts are the same as the 94-up Integra mounts with the exception of the A/C bracket.

basicly swapping any B series motor, be it a b16a2 or the GSR b18c1 is gonna be the same. My suggestion is to swap in a b18b and boost it. This swap can be done for less then the b16 and b18c1, and with boost it will be far more powerfull then the other 2 alone.

try that, it is the local forum in salt lake city. I have ridden in the car that the motor is out of and it pulled pretty good.

Thanks for the info. I am still surfing through lots of good threads and I am learning something each time.
