First off introduction. I don't own a MR2 but I am a hotrod nut / tinkerer. I have a S10 pickup with a LS1 installed.
www.geocities.com/jays_s10 Forgive the age of the site, I really need to sit down one day and take up to date pictures of everything and document the entire LS1 swap being I've redone somethings different from the website.
I'm now working on my 3rd LS motor swap. My one buddy owns a performance shop (he mostly does roll cage installs ect ect BTW if you guys are looking to get a custom cage installed and are in the DC metro area I can get you his info he does mostly Chevrolet stuff but he's done alittle of everything including custom turbo kits for Vipers and such. He does just about everything involving metal work). In any event customers have been bringing him motor swap projects and I've been helping him with the major electrical stuff like modifying the harness and integrating factory gauges and stuff so they will work with the LS1 PCM (I used to be an electronics repair guy by trade in the Army so I'm not afraid of electronics) The 2nd swap I did was a 95 Impala SS and it worked out great. Worked just like it came that way from the factory. This 3rd one is alittle more of a challenge. We are swapping a LS1 into a 1952 Austin Sheerline 125A. The guy wants to turn the car into a modern V8 powered limo. It's not a hot rod though, (that would have made the swap easy/easier). Some of his requirements were that the car have AC installed (didn't have it originally), have modern EFI fuel injection (ok alot of wires), have power steering (again not original and requires that the entire frontend be redone) and have power assisted brakes (argh). He wants it so his wife could drive the car if needed, he apparently has 2 of these things.
Well, it's the typical 10 lbs of crap into a 5 lbs bag deal that goes with motor swaps but there literally is no room up front down low on the motor. The frame is narrow up front (original motor was an inline 6) and basically I have been unable to locate any motor accessory drives that will allow me get the Alternator, PS pump, and AC compressor all in the small area I have work with on the front of the car. We have room to raise the motor alittle, but the motor has to sit low in the frame to keep the driveline angles in check so that's out. I gotta think outside box on this one alittle I guess. I was looking into the MR2 PS pump setup off a 95 ish MR2 but I have mucho questions. I understand from doing a search on here and on yahoo that the unit senses vehicle speed and adjusts the pump voltage accordingly. I've looked high and low for info other than just a basic description of this pump (I need things like diagrams and possibly other needed parts and so on) so I can figure out what I need to do here and if the MR2 pump is really a viable option. There are electronic assist kits from Flaming River steering products and Unisteer but neither of those units are going to work due to the size of the motors and where they would need to be mounted on the steering shaft (no room). I have plenty of room under the car so I could just bolt an electric pump to the frame and run a remote reservor to pump. I just wanna get an idea of what all is needed to do this right. I've seen on yahoo a guy that put a MR2 pump on his jeep but he didn't use the controller box. I see three potential problems with this. A. Running full bore the whole time can significantly shorten the life span of the pump. B. It can cause the steering wheel to feel dead or light. C. Being the LS1 uses all kinds of electronics on it and the combined load of things like the AC, headlights, windshield wipers, ect ect combined with the pump running on reckless abandon it will pull much more power from the vehicle than needed, possibly more than the alternator can supply. The LS1 alternator is about a 100 amp unit. Just the fuel pump itself pulls 20 amps ect ect. The cooling fans on high speed will pull about 30 amps, just the coil packs for the motor pull 20, plus he wants to put a modern CD/MP3 player with a nice set of speakers installed with an amp. I'm sure you guys got the idea here. Any information or website links you guys know of or any info to share I would greatly appreciate it. I need to figure something out because I just don't have the room for an engine driven pump. Thanks.
