In reply to -Posted 08 September 2011 - 06:44 AM Do you have more picture of the tunnel modification and how you customize the engine mounts ? Thanks You I'll get some for you but I really want to drop the engine at the front mounts a bit so it sits a bit more level, and its possible that the tunnel wont need modifying, I just bashed it coz i wanted to get it in quickly so i could get it going and do skids. Rocky.

Yeah the RX70 is done, just need to save up to make it sit a lot better on the road, it's been a while since I've written anything on here. I started working full-time at Toyota again to get some money flowing in. Trying to get Coilovers all round instead of granny suspension, also I want to get a different intake manifold and side draft carby for it to go harder. Its all work in progress. It drive's but its just a bit Kiwi spec atm. Lol... I'll post some pics of the skids i done. Rocky.

Yeah i've got the 32/36 Weber setup it goes fine on standard manifold with small adaptions. That first side draft manifold looked like it would put the carby's close to the strut tower aswell, I'd Rather a big C flow ram manifold kinda like the 4k-e fuel injection manifold. You'll get higher response with more ram.

Tried doing the conversion as simple as possable without doing to many customizing. It worked out to be pretty cheap seen as how I already had the engine in my garage. More to come...

I can help you out a bit. Been trade qualified Toyota technician for about 3 years now, and own rotaries since i was 16.

Hey rollaclub memebers. If anyone needs to know how difficult it is to get a 13b rotary into a KE70 Corolla, I can tell you. I've done this. Things to consider:- -turbo or N/A -gearbox type -fuel injected or carby -series of rotar -type of corolla KE70 or AE71 -budget $$$ What I chose:- -N/A (extend port)150-200hp -RX5 5spd Gearbox -48mm IDA Webber Carby -Early 4 port 13b w/ s3 RX7 electronc distributor. -KE70 (clean no rust) -Less than $1000 (lol) all labour done myself. Already had engine, cost about $2000. Okay for those of you that still want to read on about what complications I came across here it is. My first thing I should have considered was put the rotary into a AE71 body, this is because they already have the pedalbox to suit a hydraulic clutch master, which rotaries run. Also that the KE70 4k pedalbox has a pull type clutch pedal fulcrum, its completely different to what you need to get the clutch operational. Pedalbox: After perchasing a AE71 pedalbox, clutch master, clutch lines, removing the whole dash assembly, cutting a hole out of the firewall for the clutch master and adapting the pedalbox. I was ready for the next complication, the trail fitting of the 13b to see how it can be placed in the car. I sit the motor and gearbox in the engine bay roughly where the gearbox mount goes and tried levelling the engine with the KE70 gearbox cross member custom fit to my rx5 gearbox mount. The way I fit this 13b in is front engine mount and gearbox mount only, (copied from RX3 design) Lowering the engine in I found the steering shaft coming out of the firewall hit the back RH/S of the engine and would interfere with the exhaust. Not only that but the gearbox tunnel even with the narrow rx5 gearset needs room for the gearbox release bearing fork, which was hard pressed against the firewall at this stage. How I overcame these problems. Steering: I moved the steering rack to the RH/S 40mm by cutting the original rack mounts off and welding them in position. Other conversions i've read lower the rack. I found my way works ok provided you buy a steering extra lock spacer to make the LH/S rack end longer, and then shorten the RH/S rack end this will centralise your steering. Gearbox tunnel: What i did wasn't really recommended as I beat the tunnel out for hours with a 3 lb mini sleage hammer. I only did this because I didnt have a welder suitable for welding tin to make a new tunnel, otherwise I would have cut the tunnel out and made a new one. It needs to be similar to the way you cut the firewall on a 4A-GE 20V conversion for the distributor. ...to be continued. Rocky.

Pretty sure Car enthusist's will do whatever they want because in their mind it is alright with them. Nothing is wrong and only looks good to people who like it. ...for the person who said 17" wheels will decrease hp, your kinda wrong because if you keep the same overall diameter of the entire wheel it won't change anything except tyre roll when cornering because you have a lower profile on a 17' wheel. People who stretch narrow tyres onto a wide rim are just coping the Jap spec drifter trend called "hipari". Theres not much difference than a low profile on bigger rim just that you get less traction. Try getting some decent hp on a "hipari" 9J 185/60... It be like a wheel barrow with a V8 attached to it. In saying this all it is just my opinion. Each to their own.... Also if you wanna do something don't sit around talking about it. Do it! To the person who started this topic Bigger rims on a KE70 you can do it I'm doing it to my gf's Auto KE70 and all i need is spacers coz the offset of the rims is wrong. But in my words i think it looks good. If not as good as my RX70 which ill be running on 15" wheels.
