HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

ecotec swap

Post  sharkey on Sat Nov 22, 2014 1:53 am

so im in an interesting situation, ive got an engine with no car to put it in. a few years back i built a friend a 2.2l ecotec and he has decided to scrap the car, and as such im getting the engine back. its turbocharged, right now its putting out around 300whp, however 400-450 is just an injector upgrade and more boost away (i built the engine for that sort of power, the car it was in just wouldnt take it). its using a megasquirt 2 for engine managment.

so im considering putting it into a 944. ive found a real nice 86 n/a car thats begging for more power. i havent run across an adapter plate for the bellhousing, however thats not really an issue for me, ive got a cnc mill at my disposal, as well as have a water jet shop close by. i think ive got the clutch figured out (ecotec flywheel and pressure plate with a 944 n/a disc). im able to fab anything i need to, i cant see anything there being a big issue.

what do you guys think? anything big i should know about?

Turbo placement could be tricky. My initial plans were for an inline 5 turbo Audi engine but fabricating the exhaust manifold was beyond my abilities. Nothing off the shelf placed the turbo in a workable location. Good luck.

What about a rear mounted turbo, I see quite a few camaro's done that way?

rear mounted turbos can work well, however the oiling system adds a little more complexity. you either need to run an oil scavenging pump to return the oil back to the engine, or run an electric oil pump, oil cooler and tank in the rear just to feed the turbo. the scavenging pump is the better idea in most cases.

i dont think turbo placement and the exhaust manifold should be a big issue for the ecotec. the solstice/sky aftermarket has some stuff that may work, and if not im able to jig up the turbo and have one of the guys at the shop build me a stainless manifold.

i said in my last post that i had found a near perfect car. well, it was in pics, i hate when sellers post pics of the car from when they bought it. it was a bit rough, and the history report showed up with some massive accident claims. guess im on the hunt for another car

well the hunt for a car is over and this project is a go. i found another 85.5 n/a 944 thats perfect for it, ive all but signed the papers. the car is all original, ill be the 3rd owner.

its gonna take a bit before i get very far, but im gonna keep this thread updated with progress and pics.

well, bought the car tonight. after owning it for 2 1/2 hours it puked something out the front of the engine. had a good size fireball under the car, lost oil pressure and coated off the freeway. end result is no oil in the engine, the front of its soaked. guess its a good excuse to start tearing it apart right away, just would have been nice to drive it to my shop, not tow it.

The natural habitat for a factory 944 is on the back of a tow truck. Congrats on the purchase!

lol yea. had to tell the guys at the shop no jokes about a porsche on a tow truck.

got the engine bay and underside degreased a bit today and started pulling the engine. got close to having it out and for some reason decided to pull the oil filter. turns out the giant leak i had was the oil filter was loose and it pushed the seal out.

well i havent wasted any time getting it torn apart. old engines out, engine bay is all cleaned up and stripped of all the unneeded crap (which surprisingly isnt that much). i also pulled the ecotec out of its old home today and got it to the shop, ill get it washed and then its ready for the fun to begin.

ive been looking at some options forgetting the engine in and it looks like itll be more difficult than i first though. difficult, but not impossible. my first big hurdle is getting the engine bolted to the torque tube. i was planning to use the solstice bellhousing, however its a deep bellhousing, looks like its 1 1/2" too deep. there are several aftermarket bellhousings available for the ecotec, quicktimes makes one to mate the ecotec to a t56, it looks like thats going to be the right depth with an adapter plate to go from the t56 pattern to the porsche torque tube. i might also look into a custom bellhousing, i have the contacts through my shop or the guy who makes the bellhousings for quicktimes. next hurdle will be the oil pan, the sump is going to occupy the same area as the cradle. i know there are a couple aftermarket wet sump pans out there, however i may just modify the stock pan myself.

so i got it hanging in place tonight

[You must be registered and logged in to see this image.]

ive got a lot of work ahead of me to get it mounted. the solstice mount brackets i ordered are not going to work, so ill have to fab those from scratch. im debating weather to cut the stock oil pan up or get a flange cut and start from scratch. if i use the stock pan ill have to cut the sump in half, then extend the rear of the sump to get the volume. the oil filter housing hits the firewall, although i think thats just going to take some hammer modding to clear. this motor has the egr manifold piece on the back of the head, im considering cutting it off as its just about touching the firewall. it also looks like im going to have to go with manual brakes, the booster is very close to the head and there looks to be no room for the intake manifold. i did count on making my own intake manifold anyways, it just looks like itll be a little more complex.

for some good news, i figured out a solution for the bellhousing. the quicktime ecotec to ls1 t56 bellhousing is the right depth to make a 1/2" thick adapter plate. so thats one issue sorted out.

so ive been slowly plugging along. i did some firewall clearancing and cut some useless stuff off the engine (egr crossover and part of the oil filter housing), and it now fits in the car, aside from the oil pan. ive removed the brake booster and master, and have a wilwood tandem master cylinder on order. also removed all the a/c stuff, re-routed the wiring that was across the firewall, and got rid of some of the brackets i wont be needing. also decided im going to de-power the power steering rack, i figure it shouldnt be too bad to drive as i figuring im taking about 100lbs off the nose of the car. ive got some ideas on how to lock out the torsion shaft in the steering rack, however i need to get it apart to see for sure.

bellhousing is still up in the air. i figure i can make the quicktime one work, however considering the cost to have the adapter plate i need water jet cut, the cost isnt all that much different than having quicktime make a custom bellhousing. im also able to get it made shallower so i wont have to make a pilot bearing adapter.

anyways, now for a couple progress pics. here is what i ended up with roughly for room between the block and the crossmember

left side of the engine. the plastic intake is just on there for a reference.

[You must be registered and logged in to see this image.]

miles of room for whatever turbo i want. maybe i should have 2 or 3 lol

[You must be registered and logged in to see this image.]

used my friends micro cnc milling machine to make some parts. got a set of 1/2" subframe spacers cut, and a bracket to mount the triple wilwood reservoirs

a couple of parts showed up today. nothing thats really needed right now, or going to speed up progress, but a couple parts none the less.

[You must be registered and logged in to see this image.]
[You must be registered and logged in to see this image.]

the intake flange is from level zero motorsports. im not sure if im going to build my own manifold from scratch or use the flange as an adapter to run an lnf manifold. that will come later.

im sure a few people will be interested in the oil filter adapter. its from cbm (custom billet motors). its designed to thread in place of the factory oil filter cap and allows you to run a remote oil filter. this makes a remote filter a real easy thing on the ecotecs, no cutting the filter housing off and welding fittings to the block. ill be running an oil filter mount from performance world, and ive got a 9x11 oil cooler ill add for some extra insurance.

also got a few new colors of powder coating powder im going to try out. still havent decided on what color the big stuff will be done in, but ive got a few different greys for stuff i want to blend in a little.

so between not having many parts and getting a nasty flu, i havent gotten a lot done. but i do have some pics. ive got the new manual brake setup mostly built and plumbed.

[You must be registered and logged in to see this image.]
[You must be registered and logged in to see this image.]

im using a wilwood 1" tandem master cylinder on a custom firewall plate. also on the plate is a summit racing line lock solenoid (just in case i wanna do a nice smokey burnout) and a performance worlds adjustable proportioning valve. it should work quite nicely with the current brakes, and with the brake upgrades im planning in the future.

i also have the steering rack powdercoated, rebuilt and depowered. i spent some time properly depowering it and locking out the torsion shaft. there is lots of info on depowdering a power rack floating around, however most people seem to avoid talking about locking out the torsion shaft, or posting pictures of how they do it. just a reminder, what you see in the following pictures is what i did, i do not advise you to do this unless you're comfortable modding your steering, and do so at your own risk. i am not responsible for anything you may screw up, crashing your car, killing puppies, etc. do so at your own risk.

with that out of the way:
[You must be registered and logged in to see this image.]

so thats what i did, if you are familiar with the inside of the steering rack you will know what your looking at. thats the steering input shaft. the torsion shaft slides inside that and a roll pin goes in the top (were the splines are) to lock it. the pins on the bottom slide into the power steering valves. there are oversized holes in the pinion shaft they also do into, basicly to limit the torsion shaft from turning more than 15 degrees. now as for the mod, i made those 2 bushings. those bushings are the outer diameter of the limit holes in the pinion shaft, and press onto the pins on the input shaft. this essentially locks the pinion shaft to the input shaft and disables the torsion shaft. so thats my method. others like to weld the pinion shaft to the torsion shaft, i prefer my method for 2 reasons: 1) welding on steering components is a bit of a no-no, technically to be dot legal you require mechanical fasteners on any connections, and 2) its easily reversible, i can change the rack back to power with another rebuild.

ive also decided on a bellhousing setup. i ordered a quicktime bellhousings ecotec to t56 unit and ill be making an adapter plate to bolt it to the torque tube. the custom bellhousing thing wasnt going to happen for quite some time, as well as i figured out how to make the input shaft the little bit longer it needs to be to make this bellhousing work. it will also give me a little more firewall room, something im going to need if my idea for a cam sensor will work.

Could you make another of the steering shaft lockup thingy?
Am I understanding right that this takes some play out of the steering response for a non-powered power rack?

those bushings take the freeplay out of the rack that you get when you de-power it. with those in there is should feel just like a full manual rack, just with a quicker ratio.

honestly, i dont really want to start making those to sell. there is a degree of liability in building something to modify a steering component, and its something thats just not worth it to me.

could you perhaps show a better picture then? to be honest i read the description several times but the picture that is posted i see nothing like what you talked about making.

sorry i didnt realise my pictures were getting cropped by the forum. ive resized the pic of the steering shaft and it now shows the bushings i made. hope the new pic clears it up.

Yeah, the picture thing here is kind of a challenge.  After some trial and error, I've figured out the best picture width for this forum is 675 pixels.  Not sure where the cut-off comes in height.  Most of the forums I'm familiar with resize pictures automatically, so this was a new experience for me.

got my bellhousing today.

ive got the local water jet shop cutting me an adapter plate to go from the bellhousings t56 pattern to the torque tube pattern. if all goes well ill have engine bolted into the car by the end of the weekend.

so i built an oil pan today

[You must be registered and logged in to see this image.]

at least a template. going to have the water jet shop cut the stuff out. the pan will be made out of 2 pieces, the flange will be one and the rest will be 1 piece. it will get water jet cut and bent on a cnc break and ill just have to weld it up.

thanks.

yea there is tons of room for pretty much any turbo i want to put on it. the intake side, thats a bit tight, ive got just 6" from the head flange to the master cylinder.
