diy rear mount

[.:Bullen:.]

I looked Into this a few months ago not much info in the uk most seem to be american builds but I'm following this so make sure you write up a detailed log :-)

 

Good luck

Any progress on this?

[Mark@Abbey m/s]

I have tuned a STS kit on a built motor , they work well up to around 0.8 bar boost then after the drop in exhaust pressure causes boost drop off , car was running a GT35 ran 550 hub bhp @ 1.2bar boost and 580lb/ft tuned with Uprev.

 

Good idea keep the boost at a reasonable level and don't make to much torque for a stock Motor.

[DR_EVIL999]

I'm looking at building a low boost mid mount setup on mine, have a holset hx35 laying around. Just gathering bits so far. Guess i'll post a thread up when I start.

[andybp]

a bit slow so far really need to get the exhaust system i'm going to use on the car so i can take some measurements but it's too damn cold out to be honest

Have started on the dedicated oil system just cut the box section stainless i'm going to use as a sump for the turbo to drain into this isn't very big will hold about 0.5l but the oil cooler will hold about the same

so should be adequate i'm going to vent the sump back to the turbo inlet

 

 

 

have actually welded this up but too embarassed to show the results haven't touched my tig in at least 3 years should have had a practice first oh well that will teach me best i do it again

Dr. Evil are you on about using the URL for the image instead of the IMG link, so photos look like

Happens to us all. Back on topic, interesting project.

[DR_EVIL999]

Where did you get your oil pump? I've seen a couple of suitable ones on ebay.

[andybp]

yep came from ebay make sure you go for a metal gear type pump as opposed to plastic gears or a diaphram as they aren't designed to cope with hot oil

gonna run it from a power controller fed from a pressure sensor so it doesn't run all out at least thats the plan

[TinkerTom]

Got a genuine turbowerx pump in my garage I'd sell, done around 30mins work

[andybp]

Ok first sorry about the lack of updates been really busy at work and to be to be honest i'm outside all day at work so dont fancy the idea of laying under the car swapping the exhaust so I can measure up for the fabrication

first off the oil system

I've had it running on the bench with some success but also some things i'm not happy about the origional sump turned out to be too small but i came across an oil tank on some old hydraulic pumps it was a bit big so i cut it in half and re welded it and welded on an an 10 fitting for the turbo drain tank now fully finished and painted dont have any finished photo's just this one part way through

 

 

there's an oil cooler on the outlet of the tank feeding an oil filter then the pump the outlet of the pump has a pressure regulator which feeds back into the tank

to maintain 40 psi at the turbo i'm having to run the pump at 8 Volts and bypass three times as much oil back to the sump as is going to the turbo to stop the pump stalling and burning out

a smaller capacity pump may solve this but if i dont have this sorted by the time the weather improves enough for me to get under the car to start the measuring/fabrication then i'll give up the idea of a stand alone oil system

for another day and go with the standard feed from the engine and a scavenge pump

 

at the moment i'm running a unichip piggyback on the car not much use for the turbo setup(although it did give me an extra 3mpg)

so this is what i got to replace it a turboxs utec ecu

 

 

this is what they used on the sts turbo's got it for a good price including the map sensor have just updated the software to the last varsion before they stopped supporting it the only thing it didn't come with that i wanted was the

remote map switch had a look around not much in the uk found some in the us but at $50-$70 seemed like a bit of a **** take to me for a switch ,a plug and a bit of cable in the middle

so after looking at the accessory plug pinout in the manual i decided to make my own the connections are pretty straight foreward it's a 4 bit binary input although the pin for the fourth bit is also listed as the clutch switch

i couldnt get the 4th bit to register it's not needed anyway the BCD (binary coded decimal) switches are generally quite expensive but i managed to get 2 for £3 and paid a couple of quid for the molex connector that plugs into the ecu

Interesting work, looks good

 

I'm sure I have a remote map switch for one of them laying around in the shed somewhere

[andybp]

Ok first off sorry for a lack of updates in my defence the weather was crap

but now i've managed to swap the exhaust over to the one i have chosen to use for this project things are happening at last

the choice to use this system was made for several reasons

1. I had the system already and 2. I didn't want to throw money at it i want to prove it can be done on a budget

This approach has caused some issues including restricting my choice of materials and this issue of clearance between the end of the exhaust centre section and the back of the car

 

I did consider cutting it back and welding a new flange on it but i like the idea of being able to put it back to normal easily and also i can still use the car as it only takes 10 min to take the back box off

so this is what i came up with

yes i know what you're thinking but bear with me this isn't quite the final product

neither is this but it's getting there the blue wastegate will go straight into the pipe from the turbo it's going to be just the one tailpipe

the silver wastegate is for the quick spool

i've still got some welding to do in fact i've still got a lot to do but it's getting there

[Briggsybriggs1]

Looks like fun doing it your self :-) good work mate

Looking good - keep the updates coming

[andybp]

with everything bolted on but the tailpipe

i don't think anyone will even realise it's there

this pic gives a better idea of the layout

view from underneath just lacking flexi pipe from wastegate to tailpipe

and this is tailpipe with flexi from wastegate welded on (absolute pig to do) need to get this all cleaned up and painted and start on the air filter not gonna just bolt on a cone filter as in the sts setup

we dont really have the climate for that

[andybp]

better pic of it mounted on car

 

wastegate flexi pipe welded on

 

still got plenty to do

steel braided oil feed and return should be here by the end of the week, intercooler and pipework should arrive next week but i still need to decide in what to do about the air filter

[Sam Mcgoo]

Looking good.

 

Good skills doing this yourself. Looking forward to seeing the finished article.

[andybp]

no new updates really the wife's been keeping me busy but the braided oil pipe and intercooler showed up yesterday 600x300 3" inlet/outlet

MMMM shiny

[Nikos350zed]

Thats a nice,intercooler how big is it?

[The Chubby Ninja]

loving this build. respect for doing it yourself and it kinda makes me want to sell the supercharger and try this......hmmmmm
