Hello Guys,
I know. I know. It's another supercharger thread lol. But i promise i did at least search before making this thread. My name is Sina and i have a place in Iran (yeah that Iran) where me and my friends come together and work on cars on occasional. I have a background of turbocharging and supercharging BMW's.
Lately a good friend of mine decided to swap a 100 series 1FZ-FE into his FZJ80 after he blew the stock engine, so we wired and ran his car on Megasquirt 3X Pro (kick ass little unit BTW, the software still sucks though). With 33" tires and so much weight around, he's down on pace so asked for a SC option. Now he being cheap, doesn't want to pony up for a TRD unit (To be fair thanks to the awesome regime we have our currency value has come down way too low) so he said why not build one from scratch. Now it being a complete custom job does not me any good from financial standpoint unless i make it more like a kit and sell it to local guys so i'm trying to be as cost effective as possible.
Here are the main parts that i'm focusing and need your help/opinion on:
- The unit itself. I will be using Eaton M90 from Buick L67 powered cars. I guess in TRD words, it will be a gen III unit, right? Now of course the nose is longer than TRD and also the intake assembly is totally different. I also can't use of the bypass valve because it's actuated by the DME so i have to run a BOV somewhere. Now if i can find the nosedrive section of the TRD kit i may be able to also run their plenum chamber (if that's to be found also as well) otherwise with nosedrive section being longer the sitting position will be totally off from TRD kit. I also need to make a throttle body adaptor if that is also not available to purchase (is it?)
- The pulley set. Now this is debatable. I want to make a pulley (or source it from Toyota if is still available) and run a similar to TRD. My friends say with that pulley there is a good chance of the fan hitting the radiator in jumps (can you guys confirm this?) so we must come up with a 1-drive system (the belt spins all the accessories and the compressor) but this is more PITA as well. (does anyone have TRD pulley size and ratios?) The bracket and everything else will be CNC'd from aluminum.
- Intercooler. Now this is a wild card. If i end up using my own plenum chamber i will add air to water to it because here temps reach up to mid 40 Celsius. Water methanol is also in the options as well.
- Tuning. This is where things get tricky. I always thought there was a piggy back and 7th injector somewhere for TRD kit then i found out there is none! To me this sound extremely strange. In this case we have full standalone capacity, but if i want to make it more like a kit i have to deal with OEM electronics. Majority of the cars here are OBD-I cars and from what i gathered it seems the AFM maxes out with boost. I will either run a Megasquirt in parallel with OEM electronics (to keep auto trans shift points set) and it's own MAP sensor or try to run a piggyback such as AEM FIC/6 and get to work it with OBD-II MAF sensor.
- Fueling. What's the rating of the injectors/fuel pump?
-
Any inputs from you guys are very welcoe. Also if anyone by any chance has pics/measurements/specs/anything from TRD kit to share i would deeply appreciate it.
