sr20 in 86

[racehorse]

hey just wondering i have bought a 86 and a sr the 86 originally had a ca in it will i need custom engine mounts cause wen we did my mates 13 ca to sr we never touched the engine mounts

Using correct grammar helps.

But from what i can gather.

You have a Ca18 ae86 and you want to know if you need to change mounts to put the SR in?

Well many variables. It depends how the previous owner did the conversion. Is it an s13 cross member, or ae86 one modified. or stock cross member with modified engine mounts.
This information will help.

im pretty sure its a stock xmember with modified mounts

[bigm]

have a look at what rubber mounts are used. if they look generic square ones then im going to say you cant do a straight swap.

in the long run it would be best to make your own engine mounts, then you can have the motor sit how u like.

Wont there be issues with the tunnel if a SR box is used?

[Sam-Q]

as above, should swap right over but use the original CA box

[racehorse]

bought sr box today so using sr box also the engine mounts are round and r solid rubber ill try to post a pic of engine bay people on here should no the car its a hatchback is purple has sic rims and dirty grey flairs and the guy i bought it off said somtin bout kaizen garage for custom engine mounts

Sam, why do you say use the CA box? SR and CA both use W71C missions, as do RWD R32 with these being 5cm shorter. Maybe marvis has a point if the clutch/flywheel area is bigger but I don't imagine them being much different.

[bigm]

CA/Sr boxes are the same, with different belhousings and apparently different 5th gear ratio.

Rb20 box is shorter, allows the motor to sit fairly far back and sit about 3-6cm futher back from the stock hole. You need to put the SR bellhousing on the RB box for it to work.

Re do your mounts and make the motor/box sit how you want.

[racehorse]

im not the kind of person that has the skills to make engine mounts anyone point me in a direction were i can just buy them

[bigm]

As far as i am aware there is no off the shelf kit available anymore, i dont think the kaizen kit is still available, someone can correct me if im wrong.

The SR box has a considerably bigger flywheel size and matching bellhousing, while I have personally had a look at both installed in a car I didn't look as closely as I could have. I need pics as proof

good website

[fantapants]

if your not the person to be able to do an sr swap, by one already done. its not a hard thing to do really.

offer beau the right money and he would no doubt have you driving one of oz's best 86 :)

I'm pretty sure CA trans don't bolt onto SR's and vice versa. If it did, what would you use for flywheel and clutch?

[Sam-Q]

well I have heard of either box behind an SR20 so yeah interchangable. You would have to use the matching flywheel and clutch; ie: CA. I will ask my expert friend on this and make a post back.

[Skylar]

I think he means to say that you can take the front housing off an SR W71C and put it on a W71C mission that used to be bolted to a CA to use a 'CA box' behind an SR. and you can do the same with VG30(non Z32)/SR/CA/RB20/KA/L motor gearboxes.

[racehorse]

i think that a ca box can be used but u need to use sr bellhousing and as i found out tonight the box wont fit in the tunnel but the engine mounts i got im pretty sure will line up

[racehorse]

and fanta pants i bought the car being told it will go in any ways all wrong now is i need to make the tunnel bigger to fit the bellhousing in

[H8CHIR6KU]

yeah ca doesnt bolt direct up. you do have to use a sr bellhousing. it is pretty pointless changing ca box into sr bellhousing tho.

rb20 box with sr bh is where its at. sits alot shorter than sr box

[Sam-Q]

wow it looks like I stand corrected, I am really confused now. Well I will be back soon once I find out what the story is.

[racehorse]

ok changed the tunnel up a bit the box now fits but engine mounts r way off think im gonna go with the guy that said weld in s13 ones but ill need to look at them first anyway the box is also sitting to far back and the shifter is nearly on the hand break any ideas on that

[racehorse]

if anyone wants any pics pm me ure num ill be more than happy to mms some pics the more ideas i got the better

yeah, when we did this conversion, the first thing we found was the shifter sits really far back. thats why you change to and rb box with an sr bellhousing. brings it closer to the original position but not perfect

[racehorse]

i just gotta run it now i already bought it and runnin outa money
