I have a 1994 del sol with a d15 and i put a garret t3 t4 turbo kit on there with a tial fmu, I wasnt sure how far to unscrew the manul boost controler but i unscrewed it a little too much hence the 12 pounds of boost i peaked at and blew a 4 inch hole in my block, i wondering if i can just replace the block and use same pistons rods ect or if you think i shot a rod out and need to replace internals? What do yall recommend

 

the block itself cost next to nothing... it would cost less and would be more work just to buy a complete short block.. this is one of the few good things about those motors

 

If you blew a hole in the block, it was due to rod failure, probably the cause of a spun rod bearing. Just buy a complete motor, as it was mentioned they are cheap. What wastegate do you have? you either have too stiff of a spring in your wastegate OR your boost controller, or both...

or are you saying the nut/bolt on the boost controller backed out and fell off?

I use red loctite on mine just to be sure lol..

sorry to hear

 

I've never heard of a Tial FMU....

Anyway, do not risk using the same rods the blew through your motor. It takes a lot of force to get a rod to break through those walls. I wont even use the crank again. Buy another D block. It is cheap. You can get that shit for like $100, head and bottom end.

 

Yup, replace the whole damn thing.

 

Well i just found a rebuilt d15 new rod bearings master bearing ect and tranny with new clutch and refinished fly wheel also new water pump for only 400 dollars so i took my motor out last night well almost out couldnt get onbe of the shift linkage castle nuts to come off but whatever its ready to come out and i guess ill put the new motor in sat and run less boost well less than 12 probably 6-8 max ill seee how that does and hopefully i wont be seeing any more 3-4 inch holes in my block lol

 

Dang pretty good deal you got there!!!!

What are you using for fuel management! Don't want the same thing to happen again, thats for sure..

 

just an fmu but i only plan to run 4-6 punds of boost this time that should be safe i think

 

Whoa, yea no wonder it went poof, I would definitely NOT go any more than 6 psi at the MOST. If you can soon, get a socketed ecu and a eprom programmer, then some bigger injectors so you can tune it correctly.. I have a pretty good basemap for a D15 if you ever decide to go that route..
