Rear mount turbo on 97?

[jmanders]

My friend who knows a lot about cars said it would be easier and cheaper to put a rear mounted turbo on. He said he could do it for $900 for everything because I would not have to get a new intake manifold or exhaust manifolds. Does anyone know if there would be any problems doing it this way or if the results would be worse? It is alot cheaper.

ok ill chime in since i know someone who got suckered into a sts turbo for his 00 camaro.

1. tuning2. fuel supply3. oil feed and return4. location location location (remeber the gas tank is back where the turbo goes)5. boost lag6. blow off valve7. puddles

it sounds cool but will cost a lot more in the long run and is crazy to tune. do it the proper way. it costs money for a reason. chose 2 cheap, reliable, fast

Someone on here (all find the thread), put a rear mount turbo on a Q45 and it's pretty sick...

Once I find the thread...email him and I'm sure he'll give you some pointers...

qsiguy is his name...email him and I'm sure he'll give you some pointers.

Good luck!!

i'm going with a rmt because i'm on a budget. there is no difference expcept for some more lag - which can be corrected with a proper size, turbine etc - and longer oil lines but there's no need for an intercooler which saves the trouble of cutting out a part of the bumper (not cover) out. tuning is the same. one thing i will try to figure out is how to make it self lubricated like a supercharger since it runs a lot cooler in the rear that under the hood.

but like flyboy said tuning equipment and dyno time if you want it running at full potential is the most expensive thing - no matter where you mount it.

If I chop the exhaust and put the turbo right begind the front axle will that help eliminate leg.

that's not a very good spot because there won't be enough room to run the intake piping etc. the best spot is to put it where the muffler sits. you'll always have some lag but you can offset that by using a smaller turbo that spools up quick. if you're looking for monstrous power than mount it under the hood. doing twin turbo to compensate for lag won't do you any good - just if you're wondering plus, who cares about a few seconds of lag unless you're drag racing a seriously built car? with a blower you'll smoke most cars out there anyways.

well i would not oil the turbo from the engine unless you install a larger oil pump and add more oil to the mix. as well as any turbo install i recomend an oil cooler. for a rear mount look into an oil cooler from a motorcycle and run an electric pump. will work much better. also since your running low boost and i personally feel if your doing something do it right wich is why im against the rear mount i would at least weld fins to the intake piping to act as a heat sink and draw out the added few hundred degrees from under the car. honestly look at the $$ difference between making a pipe from the end of the y and a down pipe vs running intake pipe, oil lines, and running the risk of bottoming out or driving in a puddle and really wiegh the difference before going thru with this. all the parts are the same except your actual turbo which would need a tiny exhasut impeller and a huge intake one to create boost. i would just go about it under the hood. save time and potential for failure on a speed bump or rainy day.

My friend did it to his M3 and he asked me if i wanted it done to my car. I was not on planning to turbo my car but for $900 for a complete setup I thought it was a good deal. And he said I could take STI's on which would be sick.

[flyboy367]

he has a beemer so ill discredit him already lol. i just read that guys page with the infinity. if its what you want go for it but if it were me spending the money (and does the 900 include a apexi or other tuner? proper gauges for monitering and tuning like boost oil and wideband o2?) i would do it the traditional way and get gobs of performance from it. i would rather turn down boost then pray it shows up someday

As a former STi owner...good luck. When mine was tuned to Stage 2 by COBB Tuning it would pull on just about anything out there other than high line Porsche's, Z06 Vettes.

However, I am also interested in turboing my 96 I30 so if you find a cheap and functional way of doing so please share. Also some Dyno sheets or 1/4 mile slips would be good before and after for comparisons.

hitting water is not a problem with a rmt as long as the filter sits inside the spare tire well. also an oil cooler isn't a must because the turbo and oil lines are cooled by air under the car - thus no need for a turbo timer.bottoming out - don't worry about that because the whole blower will tuck in where the muffler used to sit.flyboy makes a good point about more oil - i think jwt or somebody else makes an oil pan spacer that adds room for an extra quart.oil pumps are cheap on ebay but you'll need a restrictor valve not to blow it from too much pressure - i've read that a NOS nozzle works good for that.for oil delivery there's filter sandwich plates so no need for tapping except for return. you'll need a bigger fuel pump and eventually bigger injectors (those are spendy) and a fuel pressure regulator plus or an fmu or a v/s afc.there's a lot to do when putting a blower on that's why i do a lot of reading by people who already went fi and have valuable advice - start searching.

im not sure about where you live but by me a half hour of heavry rain can flood some streets up to 6" so for my area a rear mount would be no good in the rain. what i meant by a cooler was instead of running oil lines from the engine mount a setup from a motorcycle and maybe an additional can and mount it in and below the trunck to allow airflow to cool the lines and not have to worry about anything draining from your engine.as far as boost if i read the post correctly he was able to max out 3psi but was trying for 8. on a standard setup hitting 20 is usually no problem.if you can source the parts for the rear mount then you have already sourced the parts for a front mount. the only difference is an intercooler which in most cases you can purchase one from a different car on ebay for probably less the the long oil lines, boost certified couplers, and piping for the rear mount. i dont know about you guys but i found a good spot on my 95 where the stock "ram air" box was. i figure between that and maybe moving the battery to the trunk you got a nice turbo spot.

just looking at some pictures of my headers, and i think i can just turn the y-pipe around and use that for a turbo feed. just have to add a turbo flange. ill look into this more, i may not FI my car but doesnt mean i wont help others.
