1986 944 TURBO 5.3 L33 CONVERSION

i found the audi trans but did not buy it. decided if i go that deep ill just do a vette 6speed.
cut the rear spare tire well out today, the part that hangs down in the way of the trans. trans, motor, and torque tube is out of car. mustang master cylinder and hydroboost showed up today.

im thinking drop the crossmember 1.0 inch, raise the motor mounts .5 inch, mod the original 944 aluminum arms ball joint end with the early style 944 bolt on ball joints. beef up the aluminum arms about 8" back or so top and bottom with 7075 and put the balljoints 1" taller on the top side of the arms to offset the 1" crossmember drop. redrill the crossmember where the arms attach .75 inch up. of coarse drop the rear of the arm mounts .250" to match the crossmember/arm relocation. truck oil pan should fit, and my headers will almost fit with no mods. use poly on all bushing mounts. with the billet trans mount moving the trans/tt/motor back .5 " it should be a nice mod and not cost much dough and get the effect we are looking for for clearance issues.

EDIT: UPDATES

Sounds like you are on the same track as what Xschop did with his modded RX-7 control arms. Check his thread by the same.

Thought about modding my truck oil pan but it sure is/was easy enough to get the TPC oil pan and be done with it. I'm slowly mocking the cross member to engine using TPC uprights to see where I'm at with a power rack for clearance. The power rack is said to be a lot taller than the manual rack so I have issues for clearance as it is let alone thinking you are trying to fit the truck pan in the sanwhich.

I might even take a swipe at this when I get a chance just for curiousty. Have fun.

tehone, rob came over to my house in his car last wk. his car has always been my inspiration. his rx7 arms are revolutionary indeed. i like his whole car.

new 3hp mini starter showed up today. cleaned up the mustang v8 master/booster assembly. it came with the mustang firewall mount that is offset. ill have to measure it and see if its 12.5 degrees or close. cleaned the rear underbody of the car. prepping it for rustoleum black chassis paint. will clean and paint the entire bottom of the car with it. then detail the chassis and suspension as things go on it. i like clean cars. (dont chime in here cory, lol) going to prep the engine compartment in the next few days cleaning and removing unwanted pieces. will paint the engine bay rustoleum chassis black as well. this is my daughters car ultimately and she wants it the same color as my 964 rs america tribute car, porsche cobalt blue. but the paint will come later.

the rear under body is clean and painted now. the trans crossmember is clean, stripped, and painted with billet trans mount. cleaning and detailing rear trailing arms over the next few days and installing prothane reds in the bushing areas. new stainless steel braided brake hoses, boxster brembos, and cross drilled rotors. looking at some rally car billet adjustable coilovers for the rears. ill keep the thread posted as we go.

got ahold of some 7710 t71 aluminum... dulled 2 HSS end mills, and melted the tip of a tool grade Ti bit... i think im gonna stick with 7075, lol.

rating of the al7710 is 710MPa, or B95 rockwell hardness, 103,000psi. similar to light Ti and hard Cr.

Spare oem gm truck aluminum oil pan showed up from ebay purchase today. gonna start cutting it up...

cut the 1" crossmember spacers. had cut a set earlier but was only .500.

on a side note. now have all the components for my custom g5050 and g5005 911 transaxles to make a killer top end box for my ls2 575hp 911 rs america tribute car. got another g50 911 this wk from a friend of mine. so will have to start building gearboxes soon...

Will be nice to actually see a modded truck pan.

rob, it cost more to ship it to me than to buy it... lol. truck pan on ebay was 15.00, ups was 32.00 to ship... lol.

Did not like the paint adhesion in the rear underbody area... stripped it off to redo it. i had wire wheeled it and cleaned it. but it still didnt stick that well. im gonna acid wash it basically to bare metal then primer and repaint with rustoleum chassis black. found the new poly red rear control arm mounts in the shop today. 88 944 turbo "s" race car went to a new home today, thanks cory. i got a 1988 911 out of the deal

complete new red prothane "custom" suspension kit coming, thanks prothane. arp head studs, arp rod bolts, arp main studs, arp cam bolts, arp flywheel bolts, all on there way now. i am an arp dealer or i would not be putting this in my "budget" build off here. thanks arp. new moog lower balljoints on their way as well. got the msd red coils a few days ago. been mocking up front suspension and truck pan all day... some bumps but no biggies yet.

Need some pics of your progress!

Where are the pictures? Already online or on your computer? If theyre already online e.g. servimg or webshots etc., I can help post your pictures.

they are on my computer

After a conversation with Rob/xschop we both had decided to leave the stock gm rod bolts in the rods. after careful research and consideration i am now going ahead with the arp rod bolts and just resize the big ends of the rods. A 10.9 metric property class has a tensile yield strength of 940 MPa or about 136K psi. This is approximately the equivalent of a Grade 5 fastener. ARP 8740 steel comes in at a low of 180Kpsi and is typically 200K psi or slightly higher.

entire front suspension, crossmember, and struts are off the car ready to go to the car wash before more machine work on it. likely tonight the entire rear suspension/trailing arms will be off of the car as well.

Rear trailing arms, shocks, brakes off the car now. just a bare shell with an interior now. havent been feeling that well last couple of days but will be taking all the suspension front and back to the carwash in the next few days.

arp bolts/studs/washers/nuts showed up today. prothane kit showed up today. moog balljoints showed up today, 1pc .080 pushrods showed up today.

side note, going to get my wife a nice 911 this wk. she does not like porsches but is actually excited about this one. thanks cory.

EDIT; and yes its going to get a L33 5.3 put into it.

new gm oem c5 clutch bearing assembly arrived today.
