Newby, Quick Question :)

[rb30 boy]

hey guys I'm a total newby to this forum and corollas in general.

please excuse my ignorance lol.

anyhow i have searched this forum and couldnt find a good thread detailing the differences between ke55 4dr models.

I'm looking at getting a ke55 and doing a turbo/engine conversion but id like to get to know them a bit before i go and buy one.

anyway thanks for reading this post and i hope to bring some knowledge to the forum.(i don't know about corollas but i do know a lot about turbocharging :jamie:)

[rb30 boy]

cheers mate. yeah I'm seriously considering swapping over to the darkside:)

ive looked around this forum a bit and i think ive decided on a 79 ke55.

does anybody know/can measure the length of a stock ke55 diff?

i think i will cut down a vl diff to suit it but i need to be sure it will fit before i get carried away with my plan.

rear track can be found on matti kalahati's site, google for his name

well i have spoken to both the rta and an engineer today and they both told me that capacity increase of 15% is legal without an engineers certificate and anything over that can be registered once the engineer has passed it. so its looking good on that front.

what i really need now is some enginebay measurements.from radiator support to firewall,and across the enginebay from strut tower to tower(usable area)

i will probably cut the entire trans tunnel out and replace it with one from a vl.

heres a pic of the engine i have built(all myself)

[rb30 boy]

and the plenum I'm making atm.

[demuire]

That is REALLY nice :jamie:

[cookie]

mind that engine is a real monster man :jamie:

[rb30 boy]

The turbo is a garrett gt35r 700hp rollerbearing unit.And (lol) its not a quad throttle setup its an intake plenum with bellmouth runners(6 of them :unsure: ). It will have caps on the end and an 80mm throttle feeding from below.

I hope it fits too but i havent welded it up yet so i can reduce the size if need be.Plenum capacity is over 7l as it is so there is room for reduction.

Internals have been fully rebuilt,though only using cast factory vl na pistons.they have proven to be upto the task so long as you don't go silly with the a/f ratios.

The head is unported but does have tomei cams fitted.Other than that its just splitfire coils,custom manifolds,big fuel system,9l oil pan with baffles and trapdoors,turbosmart 45mm wastegate,4" dump pipe,shimmed up rb25 oil pump and thats about it.

The engine should make 350rwkw@20psi on a conservative tune.

A friend of mine has a similar setup that we built but he has only 2.5l capacity and is producing 343rwkw@25psi

 

I also have a full race jatco auto to back it up with a 3500rpm stall converter which should see the turbo onsong as it launches.

 

I have unfortunately just found out that the ke55 cannot be registered with an engine bigger that 2250cc unless i do it as an individually constructed vehicle(ie stuffing around) :jamie:

unless i source a dead rb20 block and " borrow" its numbers :o

[rb30 boy]

yes it all looks like its becoming a bit of a pain.

ive always loved the ke55 shape, and would love to do it.

300rwkw is fun fun fun:). nothing like breaking traction at 120kph :jamie:

[Super Jamie]

your engineer fed you a bum steer. check out Vehicle Standards Information sheet 6 on the rta website, it lists maximum engine sizes that can be engineered in any vehicled, the figure of which is based on the car's original unladen tare weight and can't be changed

 

an engine any bigger than that, and you have to register your car as an Independantly Constructed Vehicle. which means it must comply with all CURRENT ADRs, something which won't be easy in a 1970s corolla. the chassis and emissions testing will also set you back between 10 and 15 grand

 

and nick's right, that much power in a corolla would really just... suck to try and drive normally. it would be a fun weekend car, and an awesome dedicated track/drag car if you could sort out power delivery (and you'd change to a 5 link rear end or IRS for that) but i wouldn't even think about daily driving it

 

this engine would be f@$koff quick in a VL, never mind something about half the weight. i'm interested to see what you end up with :jamie:

[rb30 boy]

yeah oh well back to my vl lol.

might sell up when i run a few 10's and get a rotary in a ke55.

is a 13b turbo legal?

[rb30 boy]

ive just found a rb20 block for $150.the blocks are almost identical. hmm with those numbers it could all be done :jamie:

[Jason]

f@$k Yeah!! :jamie:

[Ratty]

Nice motor dude good luck with the conversion :jamie:

[rb30 boy]

thanks man,I'm pretty keen to stamp some 2l numbers on the block and go for it hey
