Ok i just finished rebuilding my z6 block its pretty much a oem rebuild new rods pistons bearing ect....
My question is i plan on boosting it but nothing crazy thinkin 5-8 pounds of boost daily, for that much boost would i need a block guard or sleeves to strengthen the block or with a good tune should i be safe without it? im only really lookin for around 200 whp like i said nothin crazy just a fun little DD (its in a sedan haha) any input would help this is my first turbo project

THanks

You really should have at least thrown some vitaras in there instead of the oem's if you rebuilding but to answer your question, yes you'll be fine without sleeving or adding a block guard.

no




but depends on the tune, period.

Blockguards ruin engines.

Is this honduh specific information, or your opinion of blockguards in engines PERIOD?

I can't see it going down in any other fashion with an open deck engine. THe OP is the perfect case in point, people hammer those things in there ***** nilly after they've had their block bored... kinda throws ---- out of kilter.

No open deck block is going to experience it's peak load where an extra brace at the top of the bore matters - if you look at the cyl wall butting against the headsurface in a mathematical light, a block guard isn't doing much more than blocking coolant flow. The sleeve is going to swell at it's weakest point that peak combustion pressures also occur - for a Honda this is 2-3 inches down the bore, way below where a blockguard reaches.

Now, there could be a (flawed) engine design out there where a block guard helps but I am not aware of it.

thanks all thats what i needed to nothis orriginally was going to be an oem rebuild but i kinda got suced in the idea of adding a little boost and after reading a few threads on this forum gathered the courage to give it a try got a hf manifold a 14b turbo so what the hell right?

yea i had also read mixed feedback about those and the instalation of those which would have been my next series of questions but it looks like i wont need to no the answer

d series + 10 lbs = turn ya out


and you want to run 8? run 20 before you worry about sleeves

ef4dr

i didnt no how sturdy the d series blocks were everything i've read so far about people boosting them have kinda been mixed info.
i've read about people blowin up on 8lbs and some people like you said runnin as much as 20lbs. i mean i guess it all really depends on the tune and workmanship of the builder but a little extra info never hurt right. and like i said befor its my DD so i cant be to carefull in my opinion
but thanks for input agian

Pretty much. Be honest here, most of the car people you mean are idiots. Some are truly nice people, but they should still have their wrenches taken away as they destroy everything they touch.

A turbo car in the hands of a n00b dies quicker than just about anything, save maybe your mom's ---- virginity after meeting me.
