Hey Guys I'm trying to help my cousin on his RX-2 , He has been building this car for years little at a time , He has swapped 3 engine and finally got a Turbo II Engine built by Him , Some good seals all New internals , Engine Pinned by him , 9" rear end or 8.8 . well anyways , HE got car running and when he just did a small hard burn out his engine twisted the bottom cross member and damaged the oil pan

His buddy is a good fabricator but he cut the bottom cross member piece almost all the way to the front , he said he don't need all that , I told him yes he does. well now tranny is against body and oil pan is leaking since he did a burn out.

He wants to know what will be the best way to fix this. what oil pan or cross member will work.,
He wants to know if a custom oil pan and custom cross member is required.?

Thanks

 

Here is the part they cut this is not the actual car .

 

This part .

 

And this is his car .

 

first pic is a converted capella ,, second pic is an rx2

completely different setups and solutions

in an rx2 there is no need to cut the crossy , in fact it is dangerous as the crossy also holds the inner end steering and suspension A arms

a reversed bump sump ( cut and spin the 13b rx4 sump ) is fitted to the engine and it should fit into the un -modified crossy

if you have cut shut this crossy, then you need a new one


no you cant just fit the capella crossy instead,, as the A-arms , drag link, inner and outer tie rods and ball joints are often not compatible unless all are very late models
( and even then the inner end of A arm is different and needs custom bush solutions )


in a capella.. an rx3 or a modded rx4 crossy is fitted up front to sway bar holes
it does not hold the steering /suspension A arms and you can modify it as required

usually the one side of each of the vertical sections that hold the motor mounts is cut shut to bring the motor mounts flat
( and rx4 crossy is also trimmed slightly )

and a GSL-SE or rx4 sump is fitted

if you car is a capella.. then you replace or repair the rx3/4 crossy and double check it hasnt pulled out the sway bar holes

 

from memory i used a gsl-se sump, but in an rx3 so that's probably not going to help you.
Bumpstart speaks the truth, although rx4 sumps might be hard to find.(i want to try and make these custom carbon/kevlar sumps!) Also i *think* when you use a rx4 sump turned 180deg you will need to extend/modify the oil pickup tube.
and since the 13b should only be 2cm longer than a 12a, while using the 12a or gsl-se front cover on a 13b turbo for the front engine mount setup, all i had to do was 'slot' the engine crossmember mount holes 1cms forward. there's not much material there on the crossmember so split the 'slotting' up by doing a further 1cms backwards on the frame mount that bolts to the front cover(at the bottom of it near the engine mounts) and there, you will have moved your mounts forward 2cm's for the 13b.
this will only work if the trans sits in the stock location, otherwise if it's too far forward to sit on the stock mounts with the slot thing, you'll have to weld some brackets on the crossmember to support the engine.
hope that helps, not really sure if i made sense, i cant explain things too well

 

Thanks Guys , Actually photos in top are just reference on what I was talking about not actual pictures. So im assuming the bottom cross member must be replaced and I advise him on getting a new Oil pan made . He found a guy who makes them custom . so Im assuming no one makes this cross member after market ?

 

the crossmember dosen't always have to be stock, you can make a custom one if you spend some time designing and building it, but make sure you over-engineer it because i know i wouldn't want that thing being weak. i'd try to find a stock crossmember. i am not aware of any company that makes them aftermarket, but there will be plenty of people that can make them for you

off topic a bit, but man i need a 8.8 rear for my rx3, do you know anyone with them for sale? ill be in sanford, florida for a couple more weeks let me know

 

Thanks for info i will forward info to him.
And their a guys in Kissimmee fl ,Xtreme Chassis shop , Michael Ortiz check with him he deals with rotaries and rx3 if not he can get you contacted with manny mazda or louis garcia in the area that know lots of guys that can help . Let me know.

 

I have 4 rx4 oil pan sitting at home. Send me his number. I am in Chicago.

 

I have a crossmember if you need it.

 

OK I'll talk to him tonight for sure

Really I will let him know and get back yo you guys tonight or tomorrow since he works 3rd shift .
