STI engine installation anyone?
 

I am slowly installing my STi in my Manx and hope to see it finished in a few weeks. I am just wondering if anyone else is going through the same painfull process now?

Thanks,
Randy

Me Too!

Not nearly as far along as you.

Porsche speedster kitcar, WRX motor, Porsche TT Wheels, 915, Uniball, no torsion bars, RX7 front brakes, 944T rear brakes.

I currently have my EJ20T mounted in the car. I have the radiator mounted in my Ghia, I also have the water lines run front to back.
I have left to run the rubber lines for the radiator, finish running the fuel lines, mount the computer and wire the engine, tidy up the engine, remount the intake(reversed), weld my reversed water manifold... the list goes on. Those are Just to get the engine running with coolant.
Since I'm doing a complete restoration of this Ghia, I'm far from having everything else lined up but that's another long list. :laugh:

I'm at about the same point as Mikey. EJ20 turbo on a bus tranny, just got the first of my water lines in this weekend, followed by the first bit of wiring and the radiator. You know what they say, misery loves company :)

Hi

Im fitting one as well into a 1303 with a G50, 26mm short torsion bars, Brembos, car restoration etc.

My WRX RA engine is thrown in to the cab but project on hold for a few months, hope to get back on to it after the new year.

i've been putting a Subie motor in my Vanagon in my head for quite some time. just haven't found the b@lls to pull the trigger (lack of time and other things i still need to finish on the bug). maybe the engine fairy will surpise me one day.

let's see some pics SuperRSi.

SuperRSI,

What is your plan for the radiator? I'm working on a Manx clone (berrien body) with a EJ22T out back. It sounds like we are working on similar projects, mine will have 17" 993 wheels, 993 front brakes, 944T rears with alum. arms, etc.

I have a berrien tube frame sitting in the garage, waiting on the body to take mesurments for the radiator.

I had the motor and 091 tranny in a '73 Super for a couple of years, I can't wait to see how it feels in a much lighter car!

I would love to see some pics of your project.

hey all, I can chime in too...I'm running a 1.8L NA scooby motor in the back of a Porsche 912.

I live up the street from zen, and have been a little inspiration for him...LOL!!!

I run my rad in back, and run a 964 decklid to help scoop air into the rear.

Sounds interesting!
Any pics of that setup ?

I have recently ordered from Griffin a modified for AN fittings Jeep Cherokee aluminum radiator. I will be running Mecca coolant which is propolene glycol that raises the boiling point to 340 without being a pressurized system. I will post pictures as I get it installed. My progress is slow now as I am real busy.

Thanks,
Randy

Randy,

Tell me more about that coolant....where do you get it from ?

Rob.

The car was built over the 03-04 winter.

Stock 901 trans, Kennedy adapter plate. I've got a 2.2L waiting to go in...as soon as I get the Miata engine in my MGB...(different project)

sjd

You can read about it on www.evanscooling.com

I have been using it in 454 powered wind machines for about ten years now. This coolant allows a smaller radiator or just a better margin of safety when the weather gets hot. With the wind machines we get heat soak as they run hard and then because of noise get shut down. While running we needed to get all the heat we could out of the coolant. Mecca/Evans works.

Thanks,
Randy

Are you planning on putting this radirator up front somewhere or in the back?

After taking a tape measure to mine, I can't see fitting anyting much bigger than a civic radiator up front (aprox. 14.5" X 17.5"). Which is where I would really like to put mine...

I'm hoping that since there are guys driving around with Civics making a lot more power than I will be, a good after market Civic radiator + good airflow will keep me cool...

How about a sirocco radiator? they're about 13" high, and about 23 inches long. in and out on the same tank as they're a double crossflow.

sjd

I talked with a guy from the Meyers Manx forum that's running a modified version of the Griffin Scirocco in his Manxter, up front, with WRX motor out back. He said it cools great, and it appears he's only running a single center-mount fan. He had Griffin relocate the inlet/outlet slightly to better fit the Manxter body. It measures the same as their standard Scirocco 22x13 model on the external dimensions.
I think that's the way I'll be going, but I'm going to see if they'll make up one a couple inches wider. 24" wide x 13" high would be perfect in my case (Deserter GT bodywork).
Jeff

nothing to see here, just posted to a previous post without reading the last one.

superRSI is there more done on this project?
I am doing the same thing, different project car... (sterling not manx)

As I am about to purchase my motor, I wanted to understand the difficulties that you have run into. I myself am looking at an 04' front cut from a subi-sti and want to make sure that I am making the correct decision as I have other options (currently running a corvair flat 6, want something lighter, easier to work with...) as such please tell me more about what you've done, run into, had to over come ect....

I have total control over the rear section of the car, so spacing ect. isn't an issue.

Also do you have a site for your project? it seems we are running alot of the same gear (alu-arms 944t brakes ect...)

Please advise.
thanks.

im new here, i been wondering around on all kinds of other forums. i have a 74 super beetle, with a jdm subaru ej20h or aka twin turbo. and keepin the twins on there n as much stock as i can. having a guy combine my wiring. just unbolted the ac, power steering pump. hooked the intercooler on the motor. in process of takin out stock beetle motor n tranny, cuttin pans n weldin in a all metal dash , all metal door panels as well. im in process of doing a step by step webpage, so hopefully when its up and running good i can post the link to help out other newbies as well.
i'll be using a 091 6 rib bus tranny. the brakes, cv's, axles im still debatin on those. will use porsche cookie cutter wheels. radiator up front, intercooler in stock position, will run a special duct work along top of roof to the intercooler. more to come in future, im glad to find others in this process as well.

Looking forward to seeing your web page. Personally I find it helps me as much as other people for bouncing ideas around and keeping the momentum.
Rich

Glad to have you here, your definately among friends. Keep us posted, I love to see the variety of ways people make the same sort of conversion.

got my motor...
 

Gents,
Got my new 05' STI engine.

Issues to overcome & the solutions to the problems.
1. This engine comes with a servo-tronic throttle body. So either hack the Suby pedal cluster for all the sensors and bits or junk it, and use the bug pedals but I need a cable driven throttle body...
2. Throttle position sensor in that throttle body must be 'replaced' with use of bug pedal cluster.
3. extra sensors and bits that will not be needed, figuring those out and removing them?
4. wire harness adaptation to the car (removal of security system/different sensors needed or not needed to be wired in or out of the system...)
5. ECU? Stock v.s. non-stock

1 - solution. Replace 05' throttle body with an older SOHC Throttle Body from a forester 2.5 (cable throttle to replace servo-throttle).
2 - solution. With the above mentioned throttle body a different TP sensor will be used, but must be wired in...making a change to the harness mandatory
3 - solution. Remove all extra bits from the motor leaving only the bare essentials to motor functionality ( debating on the AC system but removing everything else).
4 - solution. Custom fabbed harness to join new throttle and sensors into engine harness.
5 - solution. Use a fully aftermarket ECU that is custom mapped for the new throttle body and its sensors, allows for dyno-tuning and much more 'fine' tuning.

At this point I believe that I will be working with OutFrontMotorSports here in the states to get this all dialed in. They have a strong rep for doing these installs into sand rails. For me the application is similar but I will tune and build for street use. So I am expecting about $2000.00 - ish to overcome the throttle body / ECU dilema, but this will give me a "pretty simple plug-n-play" solution... i hope.

So what are others doing to work with this engine and its unique aspects?
Anyone try to adapt the pedal cluster yet? what are you guys doing about the extra parts that you don't need?

am I on track and making sense?

have I missed anything that someone doing this job already has come up against?

thanks for your time in regards.

Hi

This website has electronic throttle controllers. http://www.tfelectronics.com.au/Page...lecontrol.html

Steve

have you used this?
 

I am curious as to how you have your pedals setup Steve.
Stock?
Using the STI pedals?
Have any photos?

I would like to know more about how your using this...

Hi

I'm not using that setup, I only posted the link to help you, my STI motor uses an old fashioned cable.

Steve

steve,
what ECU are you using?

Hi

I have the stock ECU but recently I scored a plug & play Autronic SM4 at a good price. With changes that I've made to the inlet tract and exhaust system it will be good to tune it to suit.

New to the forum. Ithought this would be a good place to jump in. I put a 2.5in my Spatz buggy about 7 years ago and love it. My new project is a 1957 Fiat 500 that I am putting a STI block/DOHC head/t3-t4 turbo motor in it. Full tube chassis. I have just finished building the engine and trial fitted it.I will start a new thread when I have the car done but I thought I would post a picture of the buggy here. Gotta love those Subaru engines!

nice motor build, would love to see some more images...

anyone having any success with their builds? I am just awaiting a rebuild on my 901, and some trailing arm stuff... anyone make any more progress?

I am about to order my clutch setup and wanted to know what others are using for their motors?
If you used the Kennedy kit what clutch/pressure plate did you use?

thanks for the insights.

I have the kennedy kit, It came with my motor. Sadly it is for a porsche 930 tranny and that is sort of what is holding me back on mine. Lets see some pics of yours!

I have a sti ra engine in my 74 ghia we done this type the engine swap in my shop call outfront motorsport they can modify your throttle body and we used there ecu kit work very well.

so my solutions so far for ecu and stuff is as follows... 05 sti engine with full vehicle harness (to be adapted to this application). sti matched ecu/key/immobilizer box, and sti gauge cluster. I will also be adapting the entire fuel system including pumps and fuel tank bits. I will also be adapting the pedal cluster (hanging) from the sti because of the servo-tronic throttle and the fact that the other two pedals work fine for clutch actuaction and brake master cylinder interaction...The objective is to use as many "plug-n-play" sti parts as I can, these include stock turbo and TMIC and parts of the original exhaust system (ultimately this will be converted to totally custom install). I will also be using the water system but running long water lines up to the front of my car with a single radiator (for now) dual fan system. I am hoping to have my entire engine system on a stand alone circut with it's own dedicated battery and closed loop system. This will stand seperate from the remainder of the cars sytems including ice/cameras/security/canopy hydraulics ect... Adapted to a fresh 69' 901 5spd trans via a kennedy kit but am still debating the clutch/pressureplate combo... as well I am still trying to figure out the cv/axle combo (anyone have insights?) in that I am using 87' 944 alu arms and full brake setup front and rear. But I am running into a few challenges with getting the cv/axle combo figured out.

Before the boards went down I had found most of the information that I needed but now none of the links work and stuff seems to be not so easy to find anymore.. alas my research continues...

Here is something pretty to look at:

Hello JMD,

I am curious as to why you chose the 901 transmission to go with your STI engine. Do you think that it will stand up to the rated horsepower of the STI?

I am using a 911/01 that I found a good deal on with a 94 WRX EJ20G engine. As long as I keep it close to stock I think that it will be ok.

randyj

I chose the 901 Transmission because it was what I had direct access to at the time. As for the ability of it to handle the STI engine, I expect it not to be too much of an issue. I am not a drag racer, I will never hard launch the car in first. However, I do like to get on it in 3rd so am hoping that the full rebuild I had done on the tranny will help it last for a while. For the start of the project I will be keeping the engine pretty stock but it is still a bunch of poop to push into that trans... I have a pro - racer that specializes in the older porsche gear as my mechanic / tech adviser and he feels strongly that the setup he built for me will handle whatever I toss at it up to about 300+HP... as I see it (today) i don't expect to pass that number for sometime... I am now just waiting on Kennedy to finish my Adapter plate and my machinist to finish my output flanges...

I have now solved output flange problems and have new flanges mounted, axles built Kennedy kit in place and am just now building the transmission mounting solution, shift linkage and final trans cradle.

anyone else have any progress?

thought i mite add to this, building a 1302 for street/track, has an 091 with beetle nose cone, rjes bellhousing, albins gears, peloquin LSD, with an 02 JDM sti engine behind it, cage going in shortly, most of the work is being done by myself, if anyones curious http://s975.photobucket.com/albums/ae239/STIDUB/ check it out.
