Damn that really sucks! Hope you buy it from a reputable builder!!

 

Man that really sucks to hear this, cant wait to see the new setup tho

 

Wow, that sucks to hear about your motor. Buy carefully so you get a reputable setup.

 

ok im trying to decide on what CI i should go with..since ill be using my tvs2300 for another year or so.. then switch to a turbo setup most probably an 80mm.. so i was thinking of just getting a completely built/forged 6.2 with 9.5:1 compression.. some guys are telling me to go for a 416ci thing is i wonder how the tvs2300 will be using that big of an engine.. and how big of a turbo should i use on that engine later on probably a 91?

since im building everything in the US and sending it over here i might as well do it once and do it right

opinions appreciated as always

 

The 80mm on my 402 is quite happy! Something between 370 and 427 and youll be fine.

 

I say start with what you have, that way if you ever have to bore it out you don't have to get another block.

 

that was quick? lol 402 with an LS2 block?


thing is i don't really see the use of BIG ci's by big i mean 418+ since jarrett went mid 9's on a 6.0.. i may not run as much boost as his but u see were im going. the max i would probably do is a 402

 

Jarrett is not your typical truck, so take comparing to him with a grain of salt. Can he do it, yes, can everyone, I wouldnt bet on it.

With bigger CI's it makes driveability better since you have plenty of torque out of boost. With a small engine and big turbo it will make a lot of top end but be sluggish (comparitively) out of boost. Really comes down to what you want...

I vote for an LQ4 iron block for a 402.

 

Same

 

IIRC he's going for a roll racer. So making a lot on top is what he's going to need.
