reason i thought about the motor plate was so i could do single 5 inch off the turbine into dual 3 inch down past the engine , really dont want to dump a 5 inch downpipe infront of the front tires[/QUOTE]

why dont you want a fender dump? lol its not that loud at all! if you have solid motor mounts i think you could fit 3in downpipes between the engine and frame rails or run em on top of the frame rails.

 

I despise fender dumps on street cars lol

Tube k will allow a 3" pipeunder the k member/a arm area and still manage some ground clearance

 

lol your no fun

 

Haha, no. No more chronicles. The only other thread I am starting is over in the ECM section on how to install, load and tune the EBL-P4 from beginning to end. The 88mm was a steal at five hundred dollars, gave the 72 plus four hundred cash for it. Will say this though Junk despite all of the bickering in my now locked build thread, you were definitely right about the 700R4 being an issue in terms of its' strength, it was just a matter of time for it...

 

What are the specs on the 88? Seems like way too big regardless of the price. Dependin on wheels i've seen t4 versions do 1300hp and my friends s500 88mm makes 1100whp on a 408" lsx with more left in it. Can a 305 even spool it?

 

It's not new, it's a used Precision T88/T4 I nabbed off of a friend's Supra, same .96 a/r as the old ebay T72 I had. The 305 was just a mockup engine that soon turned into a lets see what it can do thread, but I've been slowly building another V8 based off of a 350 block that I had which will eventually go in, and then its getting sold. The T72 started making boost in 1st gear with the 305 at around 3000-RPM, then gradually lower throughout the rest of the gears. the T88 should be closer to 4000-RPM with the 305 in 1st gear, which seems high, but the next trans will get a much higher stall. The 700R4 is a great trans ratio wise, just weak as hell. If I can find a 4L80 at the junkyard, I might just go that route. Gotta talk to RBob about setting up the EBL-P4 to control it though, as he recently gave it full alky injection control too...

 

Theres a few latemodel guys doin impressive things with 4l65e's. Pretty much same thing aint it? RPM Transmissions builds them, work well in lighter cars. Theres a few 8-9 second vettes using them. But they aint cheap!! Better off buyin an 80e if u neeeed overdrive but they are big units

 

motor plate is still way cheaper and no loss of ground clearance

 

You have the skills to fab a K member too that would give you more room. Maybe oval some tube or cut & weld to make rectangle with 2 sides rounded where clearance is tight. That is the way I plan on doing my 4th gen install. It is time consuming but once it is done it is done. I tend to oversize pipe so that I don't have to do it again later when a bigger turbo is desired.

 

I agree less HP usually follows less weight so the 4l65 are a good fit. With a 88mm turbo you will end up needing a TH400/4l80e/glide in the end. The 400 and 4l80e are the best bang for the buck and reliability. The 60/65 can be used if you don't mind freshing it all the time. Gotta ask, is the weight savings and 3% more efficient worth it?
Sound like the EBL finally can control an E-trans. I would take advantage of that and go with the 4l80e. But then again, with an 88mm and the right housings it can do up to 1500 bhp so that means high way gears as is so the TH400 wouldn't be bad either. With the 4l80e you could go steep gears and use 4th gear at the track which would be better ET. Add a good very expensive torque converter and lock it to go even faster. Is $2K worth a few tenths?

 

When you are making bigtime power and running a 3.23 or similar gear, the overdrive isnt as big of an advantage as it would be if you were running 4.10s. Big power and lots of gear will tend to put you on the bumper at the track.

 

I cant wait to go 3.08 gear. Got 3.42's right now and its not terrible street driving but its 2500+ rpm on 55-65 mph roads. 3.08 is gonna be perfect yet shouldnt hurt car at all. I cant hook the power yet with 3.42, the highway gear should help. It helped my friends turbo car drop a tenth on 60'

 

Yes, running 3.23 or below works for big power and turbos. Along with big turbos usually comes with mid to high stall converters. Add a 3.23 to a stall like that and you cruise slipping a lot. This is why I like the E-trans so much over the old school. You can lock the converter to gain efficiency in mpg and reduce rpms which makes for a nicer ride. E-trans has lots of benefits but you can't run 1980's computer efficiently. Yeah you can kludge two computers together to run engine and trans, but just go with a mid-90s ECM that GM designed to run both.

Project89, what are you planning for stall RPM, rear gear, and tire size?

 

The EBL can control a e-trans?

Seems to me that it can't ?

I'll never run a auto trans lol it will always be full manual. Just more fun
Locked converter would be nice but a turbo converter on big power is very tight off boost

 

i have an fti 3,800 9inch converter on its way , 2:73's and 28x10.5
should be a good fit, the only thing i may change is a swap to a 3.08 gear

 

Thats what i would think as well. if you set a converter up to flash to 4k or whatever when you are making ~900ft lbs or some junk its gonna be TIGHT when you are putzing around town out of boost with 400ft. lbs.
my nitrous converter would have been awesome for a street car, its really tight.

i really like the 4l80e, but its real expensive to do one compared to the th400. and i just dont see myself doing that many road miles to need the overdrive/lockup. with a 3.08 gear, overdrive, and 28" tire you would be putt puttin on the interstate at an idle. lol

 

thats something i need to buy still , a damn good shifter for the 3 speed
http://www.ebay.com/itm/Turbo-Action-Cheetah-SCS-Shifter-TH400-TH350-TH250-Powerglide-70012-/331462149881?pt=Motors_Car_Truck_Parts_Accessories&hash=item4d2caf06f9&vxp=mtr

 

Yeah I wanted to maintain overdrive, and I heard horror stories about fitting them in the transmission tunnel, lot of banging around action needed. There are a number of standalone units out there to control the 4L80, but from discussing the electronics on another board, I can build my own controller, but I want the controller linked to the shifter itself, and that is where it gets tricky. The TCC I would just have turned on and off, doesn't need to be pulse width modulated at all, and that part can easily be controlled through the EBL-P4 by switching 12v to terminal E. The shifting though is what I needed to talk to RBob about. I can build a full manual control for the 4L80 on my own, no computer needed, been done by quite a few. But the trick is getting the 1-2, 3-4 shifting solenoids connected to the manifold switches...

 

Thats what i run. It is awesome! Kinda looks cheap and with the plastic shifter handle and such but it works fantastic.

 

yup i love those shifters

 

i got one too. lol

 

which ones are u guys using in the f-bodys , never put one in an f-body before
its either going to be the cheetah or a prostick that i get

 

im not using a console with mine, and im not sure how well it would work with one. its pretty tall and bulky. i had to make a mounting bracket and stuff for it.

 

Works fine in the console. Cheetah here. I had to make brackets and stuff as well and it does sit taller than ideal

 

thats not to bad at all, how much taller do ur brackets add to the hieght .

though my entire console is pretty beat uup and cracked i might just take it out and get the chetta console if i go that route

 

I had maybe a 1.5"-2" bracket i fabbed. You do have some ability to adjust the height there

I have a piece of vinyl around the gap of the shifter to hide the open spot between console and shifter body. It fell down abit in this pic i need to redo it

 

So you like that better than the megashifter?

I went with the megashifter. The rachet is a little funky.

the cheetah is gated, yes? So just pull down and it stops on each gear?

Does it work with forward pattern?

-- Joe

 

Mega was fun but it eventually broke on me. For one it was impossible to get cable to shift right between park and first. It was one or the other. Then it started missing shifts, i had to double tap it to get a gear. So i junked it.

Gated style cheetah is 10 times easier to work and so much smoother. It has a slight zig zag between 2-3 gear or 1-2 if forward pattern. I used it both ways and worked great. Anyone can drive it. Its like stock shifters. Mega ratchet was difficult for ppl to figure out
It also shifts so smoothly it almost feels like the cable was disconnected but it is connected

 

shops still full , rolling around and working in the dirt on ur back sucks.
but i got alot done todaysurgery with the plasma cutter and sawzall
got everythign mocked up and now just have to orde rup some chromoly tubing to mount everything.

everything tucks up nice in the front with tons of room for the massive turbo , and yes the nose fits back on without any trimming of it



cut the crash bar , going to add some sort of bar back in behind the intercooler incase of an accident

 

Rad flow ok with that much forward lean?

 

how will you fill the coolant?

 

That's about as much forward lean as a fiero


youre prolly gonna need a late 90's dakota upper rad filler neck though, and a non vented rad cap

 

should be ok , btw do u have any pictures form when u cut the center of ur grill opening out , i didnt really look at mine yet but i plan to cut the middle out

non vented cap on the radiator , with a remote fill/cap in the upper rad hose at the highest point

 

Nice, you already had that covered.

 

lol yeah i try to plan ahead when possible

waiting to hear back from vs racing im either getting an s475 , s480 or an 88mm with an 83mm turbine wheel

 

I'd use a ybody coolant tank. Has the filler cap in it.

-- Joe

 

You mean the iroc plastic grille piece? I just removed it completely. I dont recall cutting anything else out for it

 

the piece behind that , iirc ur grill opening is 100% open aint it

if u look back at the pictures before i took the bumper cover off u will see what im talking about , thats not the iroc grill its the piece it screws to

 

u can see it here , if needed i can grab a bette rpic

 

Oh lol now i remember lol i did cut it off. Let me see if i have a pic

 

I guess i just dremel cut off wheel all the plastic

 

thanks , thats prolly my project for tommorow

 

converter is here 3,800-4k fti stall


maybe this weekend ill get some of the th350 assembled

 

its going to be close to the 70's the next few days and over the weekend hoping to get alot done.

the goal is to finish welding up the passenger side header and get the whole turbo hotside done

 

I have not touched my car in over a month. Picked up another toy. (picture attached).

I'm pretty sure the VB is Hughes 3215. I had hoped there would be a number or something etched into it, but not so. I did some google searching and apparently everyone uses those same GM castings and modifies them. (which makes me wonder why people don't just DIY and save $500). The only thing I found odd was it was assembled w/out seperator gasket. I included the plates in case they were special.

The other thing I found odd was I counted 15 instead of 17 return springs on the direct drum, but then when I spoke with Hughes they said that was part of "Tuning" and had to do with how quickly you want the TB to release. I find it interesting that you have to take 50% of the transmission apart to "tune" that aspect haha.



-- Joe

 

I'm still looking forward to seeing this completed. Mine is off to the body shop this weekend and I also picked up a new toy . One for me and one for the wife

 

meh snow toys , u guys need some dirtbikes , im prolly picking up a honda xr250 next weekend , only thing nice about snow toys is it doesnt hurt nearly as bad when u come off of one of those things at speed

 

No but I almost had a heart attack digging it out of a snowbank earlier.

-- Joe

 

Hah. I already have a 2012 trx 250 and a trx400x . Got snow toys and spring,summer,fall toys covered. Lol
