T-18 Rack and Pinion conversion	Mon, 28 March 2005 12:03

ive got the engine bay stripped for spraying, and decided its time to do a rack and pinion conversion now. so ill try keep this page together with how it all happened with pics and everything, but first, if anybody has any good info i could use or someone has done this conversion before, i could do with some help! as far as i know AE71/KE70/AE86 all share the same steering? i plan on heading out to wreckers soon and taking all the gear off any of the above cars that looks to be in good condition jesse [Report message to a moderator]

AE86 power sterering rack will have the correct steering geometry, but you'll then need the power steering drag links, crossmemeber and brackets, and column too. The inclined angle for engine mounts between T and A series motors will also be different too.

ok well i have waayy too much time on my hands

Just be aware the gearbox braces won't clear the rack so you have to mod or remove them. Also, firewall mount for the rack and pinion column is different. Personally I would cut out and replace the section of firewall to make it look factory. Callum [Report message to a moderator]

well spent some time at wreckers today the ae86 steering does go in at a different angle than the ae71/ke70's steering i took the crossmemer, rack and column from a ae71, it looks like the column will just about bolt in, ill do a test setup this weekend and get some pics [Report message to a moderator]

Fuck, I just got back from a drive in my TE72 and thought...hmm I'd like to convert this to rack and pinion! Then I saw this thread Does anyone know the relative lengths of ae86 and te72 steering arms? as in which is longer/shorter. Also the length of the lower contol arms?

ae86 and te72 share the same control arms not sure about steering arms, if worst comes to worst ill just have to use ke70/ae71/ae86 tie rod ends too. they share the same track so shouldnt be any worries there [Report message to a moderator]

our old TE72 had all the bits from an AE86 Levin bolted straight into it. no firewall cutting, mucking around with arms etc. raced it for years. [Report message to a moderator]

the AE71 steering column bolted straight in! ill just have to elongate the hole for the column a little so it can come down at the right angle. crossmember and rack are bolted in. it all seemed to easy, then i noticed a problem... the rack is mounted exactly 1 inch firther away from the column than it was in the AE71...

Mate I had the same problem, no need for cutting it.. Its actually adjustable. The shaft is like 2 pieces with a join you should be able to see. There is heaps inside there enough to extended it well over 1 inch. Cheers Joel [Report message to a moderator]

Does this mean its a straight in conversion. This is going to be very useful indeed for the race car if its not too much buggering around [Report message to a moderator]

so far no buggering around, its just been bolt in and extending the length of that shaft with a vice and hammer. next i have to get some T series mounts on the A xmember, then we will see how it goes for clearance. but if anyone is putting a 4age into a T-18, its definately worth putting in the steering with it, so easy! once ive dont the trial fit of the engine, if all is sweet the steering gear is coming back out and getting a reconditioning, new inner tie rods and new bushes [Updated on: Sun, 03 April 2005 06:39] [Report message to a moderator]

Glad you worked out how to adjust it mate. Yeah didn't mean to turn it around, meant you wack it hard and it can slide out. As for this setup going in a ta22, if its anything like the ra28 it is VERY far from a bolt up job. the ae86.ae71/ke70 xmember doesn't bolt in. Cheers Joel [Report message to a moderator]

I'm going about doing a rack conversion in my TA22. It is far from a bolt in job but its not actually that difficult. I'll document everything and take a few pictures for a tech article if anyone is interested. Geoff [Report message to a moderator]

well wouldnt that mean u dont need to change ur mounts now? t series and k series are the same arent they? if u use t series mounts on a k cross member the t series block will bolt up. ALTHOUGH it might sit it a bit too fat back so u may need to move the mounts towards the front a little bit. [Report message to a moderator]
