4kq v8 conversion

[Tony Hoffman]

I've reserached this pretty extensively. I'll try to answer any questions you have, starting with the ones in this email.
 
The bellhousing is the same. You have to get a flywheel from a 5 speed V8, as they use ten bolts and all others use 8. They are NLA, so you have to get an alluminum one. There are occasional group buys, but Ben at ubernugen.com sells a complete kit with the correct clutch, and he seems pretty knowledgable about the V8 conversions.
 
It is pretty easy to wire, and you use the complete engine wiring harness from the V8. Then, there are about 20 wires to splice together. I actually started schematics of these. It's pretty simple, really.
 
The engine mounts for the V-engines are level with each other, while the inline engines are offset. So, you will have to weld the mounts in. 
 
I'd say forget the G60's. We have them on the 5000, and the V8, and they aren't all that impressive. Also, you would have to use the 90 struts, as you mentioned. Then you need RS2 hubs. They are about $500 for a pair. I'd either go with cross drilled rotors, better pads, and synth fluid. Or, upgrade them with aftermarket brakes.
 
Here's the real problem. A 4000 uses a vacuum booster right where the drivers side distributor would hit. You have several options. You can use a manual master cylinder. You can use the hydraulic setup from the V8. You can modify your booster (not easy). Or, you can use the master you have, and convert it to manual. I'd recomend changing the pivot point. That would make it easier to push, and give you the proper length of pedal travel.

I have a idea. I want to do a 4KQ V8 conversion. I have not been able to find much info on this. I know its passable, but I need more info so I can put a plan together. Can any one give me more info in this like how will ecu set up work. I would like to do a G60 up grade. I believe that I can use the brakes from a V8. I will use 90q struts and springs to make the up grade work. Is there any way to use the V8 wheel hubs on the 90q struts?? If i can make the wheel hubs work on the 90 struts I can use the rotors What wheel bearing would I use?? Is it worth it to use the V8 wheel hubs vs. the 4KQ wheel hubs?? I appreciate any input you may have. 

Thank you

 Bob
