1st Taco

Been reading this site for a while. Thanks to all for great info. Posting pics soon of first Taco

 

Hey Dutch, welcome to TW, looks like you have a nice truck.

 

Thanks Jedi, Just finished rebore and customizing engine. A lot of dough for 23 more HP. Working on suspension now. Need better traction for tight turns in thick sand. Will post with what I come up with. Posting new pics this week.

 

Welcome to TW!

You rebored the 4.0L? I didn't think the current tolerances allowed for that! I am really interested in seeing what all you have done to your truck.

Don't forget you can upload pictures to your gallery in the member's gallery section.

Cheers!

 

True 007........The wall thickness between the cylinders is quite narrow....however, after the bore and a good honing, inserts and rings were made from Astrolloy 4800. (Extreme wear resistant). More honing. New dome-shaped light weight pistons were machined along with cams. Nice to have a friend that builds race cars. Indexing for the bore was the hardest part. Will have pics up by the end of this week.

 

How many thousand's did you bore, and whats the compression now?
Sounds like a hot setup.
Welcome to TW

 

Final Bore in sleeve (3.807), Comp Ratio......11.3:1 using new domed high compression pistons, modified deck clearance, new head gasket. Runs very nice as is, but will remount supercharger this weekend. New tuning next week. May need other mods (cooling), but have to move on to suspension. Should have pics up in a couple of days.

 

Welcome to the site man! Your boosting an 11.3:1 motor?

 

Thanks 06 BSP. Yes.......we stepped back a little with the TRD S/C. It normally runs about 5 PSI. Took the pulley off of a Whipple S/C from my Ranger (slightly larger diameter).....new center hub and belt......and put it on TRD S/C. Boost should drop sufficiently to avoid detonation. Can't go any larger as the belt path is already tight. Will re-mount S/C this weekend and let you know.

 

It sounds like it's going to be a fun ride.
