ok.so a friend of mine recently did a STS rear mount turbo kit on his 350z and we got to talking about how its setup.

its seems alot simpler than a underhood mount turbo kit.reduces underhood tempsand helps weight balance(somewhat)and in some cases its more street able.. since the turbo spools slower

we got on the subject of building a custom rear mount turbo kit for my s14 that mimics the kit on his Z..

and im actually thinking about doing this..

im really into driftingand id like to keep it a street car..

would a rear mount be beneficial for drifting?

i know theirs a difference between power ranges in the rearmoutsn vs underhood mount kits.but how much of a difference would it be?

and would it be a good idea for the S chassis?

im just brainstorming the idea..id guess id have to research it more tho

ive seen some rear mount turbo kits on trucks, with the turbo and stuff under the chassis. where is the turbo at on the 350/where would you put it on the 240?

keep in mind its not jacked in the air like some turbo diesel.

in the air?

The turbo will be located where the stock muffler is.im guessin thats teh best place to put it.

this is where it is on the z



and yeah i know ground clearance is something needed to be worked out.

what i was thinking is on the s14 is to modify the lower part of the trunkremove the spare tire space. and thats space for the turbo..but then theirs IC piping.. wirer would that travel pass under the car to get to teh intercooelr..

yeahthe on the z the pipe travels along the passenger side of the car into the Fmic

thats another problem ill have to figurout.id have to run the piping through the rear susp.i guess i coudl run it through the same place on the pass side that the exhuast pipe runs on the driverside.

but then theirs still ground clearance..i like to be low.on my last s14.. it was slammed.and when i do coils on this one.it will be slammed.

idk.i doubt its a good idea for drifting tho.since theirs soo much more piping for air to travel to.and spool time is reduced..

ill loose that low end even more.. now that i have the SR

From what i have heard you don't need to run a Intercooler on them. Do them staying cooler from being under the car.

that looks like a drag setup.so i don't think ground clearance is the biggest issue

but tahts an intreseting spot to put it..no exhaust piping leading out the car at all.

and the Zs running a frontmount.chris(my friend) did say that when he sprays Intecooler spray he doenst feel muich of a differnce due to the air being cool arleady

and that car seems to be running an intercooler up frontlooking at the pipes running down toward the front of the car on both sides

oh wow..thats.. intresting to say the least...

location of a part is an idea...

i find it sadly funny that patent laws allow this..

thanks

now i know if i ever do thisto not post any pics of my car on the internet.not like anyone who sees it will know where the turbo is anyway...lol

I had actualy just started researching rear mount turbos, after seeing it in maximum boost, by corky bell. The picture always intriged me, i decided to do it after i purchased a top mount manifold. I will do it. Does'nt that say patent pending, does that mean they will get it? I put my c.d. player in the glove compartment, you ca,nt do it because i am going to patent the idea, really. I wish i could complete the car before hin hit dallas this year. I would enter it just to f with sts. Talk about bad P. R.. thats a sick looking set up on that 350.

read a magazine a long time ago about some e60 m5 that had twin rear turbos. back then i was like wtf how does this work? imean unless you really wanna be different and have a lot of time/money to play around with i don't see how the benefits will outweigh cost.

I wonder if the tuning would be any different from a normal tuning setup?

You would think it would have to be tuned for the lag you are going to get from the intercooler piping distance.

Maybe this could be eliminated with a blow by setup though?

i think you should check out cin motorsports in Charlotte NC. they did the prototype sts kit for the 350z. i think the guy(matt) is making 348whp on 10psi. i have actually talked about them doing the sts kit on my s14 if i get some discounts for it being the prototype http://www.cinmotorsports.com/

no offense to any one who likes this idea. (and i am speaking out of complete ignorance) but isnt that a bad idea to put the turbo way in the back unless u really have to?

the idea holds true for cars rearmount kits started on.like vettes..for lack of underhood space.. why not stick it in the back.

there are pros about putting it back there.but i just cant quite remember..

i have contemplated a RMT setup for a very long tme for my 3400z24

the pros are that you -do not require an intercooler.-no backpressure caused by a restrictive exhaust- you dont need to worry about rain, thats what filters are for, you could even incase it if you really felt the need.- you can run your wastegate vent without any problems

cons - one hell of alot of piping- need a dry sump wth pump for your oil- coolant lines need to be run from the block (i was going to use 7/16th hard steel lines.)- turbo doesnt spool as fast.

its a good setup if you dont have the room underhood, but for our cars. i wouldnt.
