St165 with some upgrades

    So I bought a St 165 about a year ago; Vin 0000097. So an 86 with 1st gen motor and the 150F1 box
    View attachment 960

    First week I went to grasskhana. Had a blast.

    Then a spent the week installing some coilovers (Teins). I used St185 shocks, they work with a little modification!

    2 Weeks later off to it's first track day. There were some other cars there, notably an Enzo and a Scuderia 430.
    I have photos but I cant upload them cause they are too big, (Computer Illiterate). So I found out that stock brake pads suck!!!! It was good fun and no probs.

    After that the car was good I went to an autocross at a local airfield in the pouring rain. Just a bit of an explanation, here in NZ a gymkhana is low speed 1st gear, maybe 2nd tight course,where as an Autocross is a bit bigger no straight bigger than 200metres.

    Success!! Pulled off the win! :hurray Bit of a given though as I was the only 4 wheel drive, but a win is a win eh?

    Next track day I went to was the one that Stig mentioned where the cambelt caused me grief. Turned out to be a collapsed idler bearing. Bugger.:mad:
    I met Kevin and saw his very nice St162. Was a bit annoying as I didnt even get on the track.

    I did the cambelt next week and everything went sweet until the next trackday when the last lap the car overheated. I drove home after it cooled down but eventually the writing was on the wall, Foaming coolant= blown headgasket.

    So I always knew I was gonna upgrade the car this just moved the plans forward.

    Gen 4 motors are notorious for breaking rods (Gen 3 would have been a better choice dollars wise) so now the drama starts and the money starts to go!!!

    I pulled the Gen 4 down sent the block off to be cleaned and bored and line bored if needed, (it did). I got forged pistons and rods from IPP. Good dealer and good prices http://www.importperformanceparts.net/.

    Put in ACL bearings full ARP bolt set Mains,Head studs. I built up a set of exhaust Manifolds for my new Garrett 2871 turbo. I am aiming for 350hp with good response rather than outright power.

    Next was the install of my air to air intercooler managed to fit 600mm x300mm x 75mm one in.:)

    The motor was coming along I needed a thicker headgasket cause I didnt want a too higher compression ratio. Stock Gen 4s run 9 to 1 i wanted something around 8.7 to 1. I sent the head off to be cleaned , planed , New valve seals and uprated valve springs put in and all set up shimmed etc.

    Put the motor together with new water,oil pumps. Obviously new cam belt and running gear was put in.

    Eventually got the motor together with the box and an uprated paddle clutch with sprung centre.

    I had previously pulled the old motor and box from the car cleaned up the bay a bit. This car is never gonna be a show queen!;)

    The only issue I had was my stub axles from my old box didnt fit into my new box. Well one did but the other one didnt. I got an St185 one problem solved.

    I am installing an external oil and trans coolers. I have put them in the front guards to try and increase airflow through the radiator since I have a big intercooler in front of it!! Speaking of radiators next job is to modify an Aluminium one to fit .

    I am going to run a 3' s/s exhaust, an aftermarket ecu but I will update later once I can sort out this photo issue:cuss!

    I am trying to use Picasa and resize the photos but the photos are 2Mb+ in original size and when I resize them they come across as a broken pages any help would be appreciated!!

    Welcome Bruce
    For pics I use Irfanview which is quick, free, easy and has batch conversions as well for converting entire directories etc.
    Cropping and resizing (800x600 is ideal) are real easy - http://www.irfanview.com/

    Know where I can find a 5S crank and 4 2JZ rods? - wink, wink

    Folks Bruce is one of a kind, he builds 3S motors for a living so not much he doesn't know about them

    Funny thing is I had spare tensioners and idlers in my boot but it sounded a lot worse

    Some recent pics

    Homemade headers and yes it says GARRETT, these guys are master fabricators so expect to see some radical mods on this car

    No I dont build them Stig but I do have access to people with knowledge!:D You've been looking for those rods for awhile huh? Not at the moment but I will put some feelers out and see what I can find. Cheers

    I still have all the original running gear except the shocks so if you want to buy everything and save it Lone wolf you'd better hurry with the money.!:rolleyes: I am a fan of original cars but since I see restored original cars a lot for my work I am probably a bit desensitized. But at least it is still alive and being used and not a victim of the Tsunami in Japan. I shudder to think what was lost on that day!

    lol, thanks but I stripped a st165(1988) and had all parts I needed to swap it in my ST162 allready. I need some good hoses, but your originals are toast too after 25 yearss :).

    You wouldn't happen to have foglights ? Did it have original black interior (so NOT gray) and black seatbelts?

    Bruce - all you gotta do is copy from that site page and paste here.

    Some pics I took the other day during the measuring and testing phase
    [​IMG]

    I love the new cut down & modded V8 alu radiator - put me down for one!, I want to mount slim box and engine coolers underneath/behind

    [​IMG]

    I have ST165 twin pot brakes for sale and also a set of ES300 front brakes that can be modded to fit - (for those that don't know, the early ST165 wears ST182 brakes at the front)

    Also found another under construction in your hood, also an early ST165. Sergei is fitting a 205 motor, Wilwood brakes etc just down the road from you

    Cool thanks for the tip Stig!

    I ended up ditching the stock radiator due to clearance issues and because I wanted to upgrade to an Aluminium one.

    To alleviate the clearance issue I decided to move the radiator forward under the slam panel to give me about 50mm extra room. Obviously a stock radiator doesn't fit under there! After measuring the hole I decided the best option was to buy a aftermarket V8 alloy radiator and modify it to fit.

    Why a V8 rad?
    First,they are cheap! Have you seen the price of hot rodders stuff? You can get a full set of forged rods and pistons and a crank for the price we pay for forged rods and pistons! Remember they get 8 vs our 4! Anyway I digress.
    Second, V8 rads also have side tanks not top and bottom tanks, so it easy to cut them down for height and they are available in a variety of widths so you can pick the one that suits your hole best.
    Third, you can get them with outlets where they best suit. Not that important but it does help.

    What I did was chopped the bottom off to the height I wanted making sure to cut through the fins next to the tube that I am going to discard.

    Blank off the tanks, put in an outlet and test it. If you want to pretty up the cut side, fold up a channel and put it across the bottom and weld it to the bottom of your tested tanks.

    [​IMG]

    Just under the inlet you can see a weld going across the tank, this is where i blanked off the tank to force the fluid across the radiator there is another one 2/3rds down on the other side this effectively turns the radiator into a triple pass radiator = better cooling.

    I decided not to run the trans and oil coolers in front of the intercooler and radiator and instead to mount them in the front guards.

    This of course means I have to get air to them so more holes and some ducting will be required!!

    This is the ducting that I made to attach to the oil cooler.

    Attached. The idea is to duct air from the bumper to this and then that will force air through the cooler.

    This the bumper end of my oil cooler ducting.

    It just needs a short piece of flexible ducting to join the cooler duct and this together. you can see i have cut the tow hook hole a bit bigger as well as adding another hole to the side.

    I made an airbox and a pcv catch can.

    So on with the plan. I have been working on my cooler ducting.

    These are the pieces that I made to duct the air from the bumper to the air box and the transmission cooler.

    This is them in place. Except the base piece for clarity shown from underneath. You can see my trans cooler mounted in front of the wheel.

    Front view of bumper ducting. The idea is that the large hole will take air straight to my airbox. The smaller hole will take air to flow over the trans cooler but what doesnt go through the cooler will be available to the airbox.

    See that triangular hole next to the cooler? It goes into the airbox. With the inner guard in place the air will have access to the airbox.

    Looking into the airbox from above. At the bottom of the picture you can see the triangular hole and to the left is a larger hole that I cut into the inner guard to allow more access for the spilled air. Oh and where does the air that has gone through the cooler go?

    Out through here. The sharper eyed of you will recognize that louvre as a St185 bonnet louvre. I had bought them earlier for my bonnet but decided against using them but they were perfect for this job. The air should have a path out through here and the spinning wheel should help generate a venturi affect to help pull it through as well.

    On the other side I have ducting for the oil cooler.

    I dont have the flex yet so its not in place and I haven't plumbed the lines yet but you get the idea. I hope!

    Same deal as the other side. It also has a louvre on the inner guard. See next post.

    You can see the cooler through the louvres.

    What the front looks like now.

    I can't see any of your pics Bruce - you need to use the tag or just copy/paste the location of the pic.
