Swapping the tranny & rearend in is the same process as replacing an NA setup.

10 bolts hold the rear subframe in (easiest way to convert the rear end) and then the driveshaft and TII tranny can be installed.

You will need the driveshaft as well as the TII tranny and rearend (I believe there is a small difference in length, like > 1").

Well, the quotes Ive heard on this forum are the N/A tranny can hold anywhere from 200-225 HP depending on the condition.

Mine is in good shape with only 81K miles on it. I guess it should be OK for a while. As others have stated, Aaroncake is still going on the stock n/a drivetrane I think...

I'm not planning on making big numbers... but having that low end boost is just screaming SUPERCHARGE ME!!!!

I still think the n/a tranny will hold up, but you should definitely put a better clutch in.

what's up with the post?? it needs to get bigger and then be archived! *hint* write up


How do you guys feel about not retarding the timing on this setup, personally i dont like the idea of not doing it.. Thats why i plan to run a 12a Turbo distributor hopefully. As far as fuel supply, i'd still like to know if he is running an aftermarket boost dependant FPR, or if he's running stock.. And where did you get that pulley?!

I tried to find serpentine pulley setups, but they're either really expensive or the company stopped selling them.. Will an FD's serpentine pulley system possibly be able to be modified to use on an FC?

I want to mount the Supercharger at a different angle, so i can have more room for piping. I heard that the m-90 doesnt discriminate at any angle it is placed... is this true?

Thanks.

7psi yes n/a tranny would hold up.. this is great.. im swapping my motor should give me time to prep for supercharge FC at the same time.. write up and pix would be nice.. since i have most of the stuff like safc, tII fuel pump and injectors.. no worry about running lean for this setup.

Aesop Rock

this is my next project no doubt about it, i was thinking about swapping in a turbo but this just seems so much better considering a $300 price tag to a $3,000.

FC3S-NovaStyle

yea pretty much a friend of my just did a turbo II swap.. costing him $4000 about.. this is so my way out from that

i think there should be a supercharging forum under the tech + performance, like the "single turbo rx7's" one....

bro but wheres the maker out of all this hes like disapeared hasnt replyed in about 2 days or so?? i mean cause if this guy could do a write up that would really help me from selling my GXL and instead buying a TII

I'm pretty sure he's just posting during study hall in school. Just so you know. And all you people asking about the fuel, READ, I'm pretty sure he's said that he's only got an S-AFC and that's IT.

EDIT: About the bypass valve, where'd ya get the valve and how is it hooked up? A pic would be helpful. I understand you're getting lot's of requests so I just posted something no one else was asking

Zer0 Cylinder

i may be, and probably am wrong, but i thought 1psi o fboost = 10 hp.....

so say there's 70-80 hp out of the blower.....

stock s4 engine, 146, add in exhaust, intake, sp, other little bolt ons, and you're like 170-180 bhp easily......add 70-80 hp to that, if the n/a transmission is rated at 200-225 passing through it......i dont think it'll hold up.

Chimeron

well that's not quite right, think about the stock S4 turbo and n/a. N/A is 146 Turbo is ~180 I think. That's at 5.5 psi but it's not a 55 horse difference. I know, there's difference in the engine yes, but not enough to drop it 16 hp. And even if it was, why would they drop the power just to put a turbo on it? I thought that 1psi = 10hp thing for a while too but it just doesn't add up from what I've seen.

Disclaimer: If I'm wrong about this someone tell me. I hate to be dishing out wrong data.

Zer0 Cylinder

it may be the 5th/6th port differences, i think both were designed for to get the most power out of their respective setups.....any idea what kinda power a 4 port n/a makes?

again if im wrong, someone correct me - im not claiming to be right, just what ive thought.

OK. I don't want to hijack this thread, but I will answer some of the questions that are directed more towards me.

I saw no abnormal wear on my engine. I was running up to about 10 PSI on a regular basis, front mounted TII intercooler, 550s all around, and stock timing. Had a few nasty pings at a few points, but no damage. I have since disassembled the engine so I may bridgeport it, and it was in excellant shape inside. Some chatter marks, but those were most likely due to overrevving.

I personally believe the NA drivetrain is stronger then people think (or accept). I had no problems beating the hell out of mine. I did kill two transmissions, but both failed due to lack of oil (first one lost the rear seal on the highway, then broke an input shaft as a result....second one had a constantly leaking front seal, which let it run dry a few times). I know one person running 13B-RE on an NA transmission, and another running a 6 port turbo w/blow through Webber on the NA tranny. Neither have had problems. Also, the person with the 13B-RE had run a 12A bridgeport w/blow through Webber at 8PSI and had no problems on the NA transmission.

At the moment, I am building a 6 port bridgeport engine out of the turbo NA engine. It will still be turbocharged, with probably some form of the TO4 hybrid or the 60-1. Still using the NA drivetrain.

Moderation issues: Please try to keep this thread on topic and informative. If you don't know, then don't post. Also, if you have to ask a question, check to see if someone has asked it before. I could easily see this thread turning into a 10+ page mess, and would prefer that to not happen, especially since this is obviously an archive-worthy thread. If necessary, cleanup will take place.

Chimeron

Sorry, will do Aaron.

ON topic, what about the stuff that was in the way of the place you put the charger body? I know there's differences in the S4 and S5, but I don't know if this is different, I've got several things around that area that would look to be possible obstructions, how did you deal with that?

Zer0 Cylinder

several things? only thing i really see on my s4 is the tubing running from the TB to the AFM.....which when you use the charger.....that tubing is hooked directly to the blower, then another tube is coming out of the blower to the afm. what else do you see obstructing that area?

Zer0 Cylinder

*maybe* a coolant hose, but that can be re-arranged no problem.

KiyoKix

I agree on the N/A tranny...it's stronger than some people tend to think. I'm very curious to see where this thing leads. Even if there never is a write up or for that matter another POST from him. This thing will prolly spread like wildfire and someone else WILL (mark my words) make another one that's better, it's just how things work. Either way he's started a revolution (ha...great word to use eh?) and I'm quite thankful for that in itself...even if I NEVER do one.

P.S
I prolly will though .

Where on earth is the supercharger mounted? I cant see.

There is one picture looking at the very front of it. It is very hard to see but appears that there is a bracket coming from somewhere around the engine mount up to the supercharger. I can see the bracket but can't make out any detail.

Chimeron

My mistake, I thought the charger took up more room than it does. Sorry.

cluosborne

The only problems I could see with the supercharger mounted in that area of the engine is that it'll block quick access to the exhaust manifold, ACV valve, the 6-port actuators, the split air hose, and maybe the heater hoses.

As for obstructions, I doubt how it's mounted it would interfere with the heater hoses. The heater hose from the lower part of the radiator attaches to a pipe which runs along under the Split Air hose to the rear of the engine compartment. There, it bends upward and another hose connects it (via a tight 90 degree bend) to the heater core.

What would be more likely an obstruction would be the location of the Split Air hose, which is located above the heater hose pipe. But, I'm sure that can be rerouted.

I don't think it would be too hard for him to get that supercharger back out if he needed under it for any reason.

My biggest concern about the way he did everything is the inlet and outlet pipes. He is losing so much efficiency by doing it the way he did with the small pipes and blunt transitions. Now that it is working he needs to go back and refine it alot. He'd get so much more power out of it with the same boost level if these issues were taken care of.

It is still a nice upgrade, especially for the money or lack of it. A little work could make it kick ***!

i like to see more pix.. and some write up .. to get some more ideas.. especially since im lookin to accuring the blower realy soon
