Here is a buildup of what I did

wicked header fab. work! mine dont look so slick, after i flipped the stock manifold over, it of course collects from 4 to 2, the non-cast 2 to 1 pipe section directly after that runs to the cat. converter was trimmed up to a length of about 3 inches; i made a plate to mount the charger to on the mill out of 4inx4inx1/4in plate, cut 2 holes in it the size of the 2 pipes on the manifold and welded it directly to it. I'll get a pic of it before too long cause its prolly hard to visualize.

Advantages were: little frustration involved, straight forward easy build, easy acess to try many different turbos, intake is outta the mud and water, everyone you pass gives you a 'wtf is that?' look

Dissadvanges: no hood, doesnt look as slick, turbo sticks out in the open

Haha i was talking to someone who used to race 4x4s back in the day, like "gravelrama" style uphill drags and stuff. I told them about my tracker and the stuff iv done to it. He chuckles and says, whats the point of doing that to that little engine just to trail ride?
" I dont really know. Cause i can i guess."

That's more than enough reason in my book.  And it beats the hell out of stamp collecting.

Amen to that! Might as well do some crazy stuff if i got the motivation. The worst decisions make the best stories, think i might have read that someplace on here.

Alright so talking theories here, are there any cheaper forged bottom end components available? Arias will make custom pistons for 100 a piece, or i found cbr 1000s have the same diameter, so custom rods and tougher cbr pistons would do well (crank would need balacing im sure)

but im not gonna drop $400 for something when i dont know the weakest link. Might not even be the pistons.

Might just ring the heads, add another windsheild washer pump full of alcohol and go for it

Honda pistons from SRP work, I got a low CR set, but didn't take into
account the CC of the Honda head so they ended up close to stock
CR, but I did spend about $400 on the set if I remember right, so
custom fit for the same price is good.

As far as the bottom end, Suzuki rods are beefy when compared to other
four cylinder engines, and hold an easy 200 HP

did you ballance the crank? cause theres no way those pistons the same weight

[wildgoody]

nope, never really thought about it, I should tho

[fischenr]

has anyone melted stock pistons? |removethispart||removethispart|@ what boost? and how much boost will your Honda pistons hold up to? i mean if its a heat thing I'm actually not too concerned bc of how cool alc burns (that's what most of my fuel will be at high boost) and how intermittently it hits high boost(plenty of time to cool down)

but of course too high of cylinder pressure is liable to punch a hole straight through it. same as getting too happy with the Nos

Wild: is wrist pin dia the same for the two pistons?

[wildgoody]

SRP, Sportsmans Racing Pistons, I think it is, are forged, and
yes the wrist pins are the same size. I got the wrong ones, I
just ordered by the CR instead of specking out the right pistons
that would of had the right CR for the CC of the head.

CR is determined by cc of the head + cc of the piston crown dish
divided by the cylinder volume so 10cc head+ 5cc dish = 15cc
divided by 150 cylinder cc = 10:1 CR.

for a turbo motor, 8.5 is ideal for higher boost PSI, up to 15, but
fuel is a must, and accurate too.

I would run no more than 10PSI, which will give you 2x the stock HP
approx, so close to 200 HP from a 1.6L engine in a 2500 Pound rig =
tons of fun

10psi? thats a little conservative for my taste im already running good in that range, i was hoping for someone to encourage me to up it!!

i'll keep hitting 12-15 and let you know if(when) it breaks

iv decided on a hobbs switch for my alc. and to ring the block so i wont blow the head gasket(already leaks)

One alc inector on a hobbs at 7 psi and another manual one on the lever for a second stage, good for 10-15 or so

[wildgoody]

Extended boost levels over 5 PSI can melt stock cast pistons, you've been warned 
I have some 8 PSI pics of a melted piston, BTW I was warned too

[fischenr]

Duly noted sir. we'll see how long she lasts. i might have to put a screen in the manifold to hopefully catch some piston fragments and save my turbo when she goes

[wildgoody]

I had a meltdown, thru the top of the piston and out the second ring land,
erroded the ring into the oil and trashed the oil pump, never had a chance
to shut down before damaging the #1 and 2 rod bearings and crank, was
quite the mess seeing I was in Beaver Utah, heading zukfari at EJS

ha yea if i planned on being far from help i def would cut it down some. most places i ride are within 5 miles of the trailer. by the way iv been running this set up since the begining of April.
