Looks nice. Probably a hell of a lot easier to maneuver in there too vs the original hard plastic.

Benjam

Thats the whole point.I needed it flexible so it wouldnt touch my down pipes.gonaa bend it up to the floor board and up the firewall.the old plastic comes straight out to frame rail..

right where my pipe runs.

So made some other videos. One of it reving and then open, then one of it smoking..

Have one issue tho I had to use clamps on the cutouts, not allowed to full weld but are allowed to tack.I didnt tack because figured clamps would be enough. Well they have spun slightly and the tail pipe hits the frame when reving hard..(also to note I have a broken trans mount AND a engine mounts, been to lazy to fix) BUT im going to throw some spot welds on it to keep it from spinning. .

Should have line in tomorrow, going to plate the firewall also.seemed to flex when pressing the clutch..

********ok let me just throw this out there********

Any mods that have been done or will be done may not comply with your local laws,this is not a street truck any longer..it is a weekend track toy..you would need to research your own local laws to see what you can and cant do.....

Got the IC stacked.was pretty straight forward, just had to drill the threads out in one of them and get 2" bolts.what I will say and has me slightly concerned, is all the weight thats ontop of the lower intake..my mount is steel, these things combined are pretty heavy and then the charger..thats ALOT of weight and considering my lower is ported paper thin, plus the lower intake to block is famous for leaking

I dont think I could put any bracing anywhere to try and distribute the weight, only thing I have now if from the tb mount to the head.

Last concern is the added 1"..in my explorer I had tons of room but had a 3" body lift.I know without the IC it fits under a ranger hood, dont know by how much tho, the previous owner had a ranger.i have never tried it with or with out IC..he said he had a couple inches of clearance, plus I added ruffly a 1.5-2" with my cowl hood so I """SHOULD"" fit..

one dual core 2" IC said to reduce temps around 160*+ depending on variables.I was seeing maxish of 140*ish at WOT @ 10 lbs of boost with ambient around 80*ish with one core IC..theoretically I should see ambient now till around 12-14 lbs of boost.that means tuning is going to be easy and we can really push it.my 2.7 pulley should now give me 15.31 pounds and my 2.5 pulley should give me 17.71 pounds..im probably not going to run the 2.5 tho, thats really spinning that thing fast..if 15ish pounds dont give me the power I need I always can up my nos shot

Any rate im getting EXCITED now!!

And purdy it up some..

jd4242 · September 15, 2014

So the other night I heard a very disappointing sound..my passenger pipe fell off and almost dragged the ground..all three hanger broke on the passenger side and two broke on the drivers.thats 5 of 6 broke!!

there REALLY wasnt much weight or tension on them either.

I have replaced them with heavy duty ones and tacked the cutouts to keep them from spinning. .im sooo mad I had to redo it and that I almost dragged my pipes..I would have been extremely pissed if I would have..lesson learned. .no cheap Chinese CRAP ever again!!!....

I wasted the whole weekend fixing them so didnt get my header panel installed so im now a week behind on the sc install!!

1 of 6 left!!

What I replaced them with..

Its a good thing you caught it when you did!
I checked out the link you posted and that looks like quality stuff. With those and tacking the cutouts it should hold real good.

Yea its in there good now.my fat ass could hang off them

I just hope the sound gets better with the new motor, you can definitely tell they are to big for stock

So got the passenger side valve seals and covers changed out..the seals were so bad that some were just moving around on there own..all had oil under the seal...also i have never seen these types of seals before.

The valve covers had been off before tho and someone lost the wings for the bolts.I picked up a spare set of covers and wings from my buddy..but its sealed up now and runs better than ever before..ill do the driverside when I put the charger on..

I also broke out the charger and gave it a bath and fresh coat of paint..hopefully tomorrow I can get the header panel in and heat exchanger mounted.I have to work sun

And finally got a good pic of the blue

jd4242 · September 20, 2014

Header panel is done.took a little bending and washers but went back in pretty nice.now the heat exchanger will fit so going to try and tackle that this week.I painted everything up but of course didnt take any pics..ill post some with the HE installed. .

Got a couple more gauges to mount and wire but hopefully the charger will go on this weekend

Bend piece stopping me from mounting my HE

How it should look

Looks great!

Sure Does!

Ranger

Very Nice!

jd4242 · September 23, 2014

Thanks y'all. ..

Well CRAPP!!!! Just thought of a big problem and just talked to my tuner and confirmed it....I have talked to him previously and he said the chip and tune ""should"" just swap over being same motor and blahh blahh...well I forgot to tell him my ranger has TWO O2s and belive its batch fire injectors. ......the ex was a single O2 and belive its called sequential fire injectors. ....

I called to confirm this info and he did..soooooooo what that means is the tunes on the chip wont work as a plug and play deal..a whole NEW tune would have to be made.....my plan was to run what tune I had then once the new motor was done take it in for a ""tune adjust"" there is a HUGE difference in pricing from a ""tune adjust or whole new tune""

So long story short..im not putting the charger on till new motor is done

im calling TODAY and ording the pistons..if Manley wont make them I know JE will!!!!

jd4242 · September 23, 2014

I am moving along with installing the HE, pump and gauges tho.I got the distribution blocks today will all my new fittings and hoses.going to try and mount the HE today..I ended up with 3/4" to two 3/8" and went with clear hose this time so I can see the flow..

Turdle · September 23, 2014

Which "years" are you dealing with?

Older would be batch fire I think, and,newer with 2 o2 sensors would be sequential.

Look at the wiring harnesses to be sure. Batch fire injectors will all be the same color wiring per bank ( all injectors on one bank will have the same wire colors) sequential will have different colored wiring on each injector --except for the common wire which will be the same color on all injectors.

My explorer was a 92 with one O2 and batch..ranger is a 94 with two O2 and sequential..if I knew it was going to be a problem I would have bought a 95 with obd2 and a hand-held, then sold my sct chip..I specifically buy a 94 because I was told it was the same and the chip with swap back and forth

I PAID ALOT of money to have that thing tuned and now he has to start all over!!!!

jd4242 · September 24, 2014

Woooohoooo pistons are ORDERED! !!!! Manley was giving me the run aound on the min quantity that you can order. .when I ordered my valves he said he could do 6, then I cqlled back to get some specs and told me it was like 30 minimum qnd I just called again to only get a run around..

So I called JE pistons and talked to them about getting a prototype asymmetrical piston made.they were VERY helpful and sounded excited to make me a set..so they took all my specs and deposit. .they are going to meet with their team and get a cad drawing up.he said after the meeting they will call me back to confirm all the specs will work and discuss ring grove width and ring type..all said and done it came to $1,231.59.......just about where I was expecting. .thats for pistons, rings, pins and locks...

If you haven't seen or heard about the asymmetrical piston you should check them out.pretty cool idea and is pretty new so makes me slightly nervous. But if they do what they say ill be super excited to have the first set of protype 4" piston ever made...

yes ever, they currently do not offer that piston for any motor in that size..I have a feeling they were already prototyping a 4" design as its pretty common size..

Have a look

Really good read and like I said thought they were probably planning a 4" piston. .lol

That LS1 sure seems to be the hot ticket in making good power easily.
