t18 crosmembers

[stx-16]

Car - ke70

motor - rite now 4kc but im thinking about going 3tc, 4age small port or 18rg

use - drift and some street driving

problem - wanting to know stuff

occurs/started when - i got the car haha

personal situation -please help

1: will a t18 g-box crosmember fit a ke70 for a 4age conversion?

2: will a t18 g-box crosmember and engine crosmember fit a ke70 for a 3tc conversion

3: will a ra6X g-box crosmember and engine crosmember fit a ke70 with a few extra holes drilled fit a ke70 for a 18rg conversion

add 2tg to that list with t18 x-members etc

[blair]

don't go 3tc unless you plan on either

a) only sliding in the wet

or b) opening it up for some work

OT: no clue. but would also like to know :)

1 - Crossmember yes.

2 - Crossmember Yes

3- Unsure, but likely with some extra holes / filing. Although putting an 18R-G in a KE70 is silly unless you already have one.

I mounted a 2tg in my old ae71. I hung the motor and box in off a engine crane and used the standard ae71 gearbox crossmember which bolted straight up to the celica type t50 that was behind the motor then made some simple engine mounts using a couple of nissan patrol panard rod bushes, pipe and flat bar. with the engine/box fitted like this I used a 2 peice tailshaft from a 5speed 4kc ke70 which bolted up sweet as the older t50 output shaft spline is the same as the k50 and the length was just right. I'm not 100% sure but i think the 3t/18rg dimensions are the same as 2t so this setup may work for you.9898

well i have access to all 4 engines so its just a matter of making my fucking mind up
i kinda really dont want to do a 4age 16v just becuase its been done the shit out of witch is kinda good but not for me
yeah some say i like to make it hard for myself

although everyone does 16v's the conversion is popular because there a good engine and easy conversion
3tc's are a pretty lame engine unless you open them up and upgrade stuff as blair said
i dont know much abotu 18rg's but i would think they put out similar power to a 16v.

18R-G will be a decent powerplant if you have the early 88210 model with the nice high-comp pistons and aggressive cams, the later ones are a bit so-so without work. Keep in mind they're a BIG motor compared to the 4AG and weigh alot, your car will be a marked amount more nose-heavy.

As typical as a 4AG is, they're an ideal motor for the E7 chassis.

3TC is pretty poey without work.

The figures are indeed close:

4AGE 100 kW at 7200 rpm 149 N·m (110 lb·ft) at 4800 rpm. (Smallport)

18R-G 82–108 kw at 6400 rpm 177 Nm at 5200 rpm 1973–1981 (88210 motors)
18R-GR 104 kw at 6400 rpm 169 Nm at 4800 rpm 1973–1975 low compression for regular fuel (8823x motors)
18R-GU 97 kw at 6000 rpm 162 Nm at 4800 rpm 1975–1978 emissions control - Japan. (8825x motors)
18R-GEU 101 kw at 5800 rpm 172 Nm at 4400 rpm 1978–1982 EFI, emissions control (Japan) (8827x motors)

I would still go Smallport over 18R-G in an xE7x, there's just too many things that make the 18R-G conversion a headfuck (hard to get parts for, more difficult to fit, weight / size, the fact i have one and you can't possibly handle being this awesome :P, only the early models are good, expensive initial purchase price most of the time)

hey hold on isn't the T18 a model that has a steering box? if so your in trouble.

Yes, but he's talking about the gearbox crossmember honeybuns.

[Sam-Q]

hahaha yeah just ignore my stupidity then

[stx-16]

yeah but i would fuck the steering box bs off lol and workout something with my 4k crossmember

[stx-16]

ok so if Evocom is rite as i dont know 100% but if the older t50 output shaft spline is the same as the k50
then would the t50 still bolt up to a 4age?
thats probly a stupid question but what ever

[Sam-Q]

not practially, you need to swap bellhousings and that means messing with shims and shit like that, theres a write-up on it on toymods

[stx-16]

oh FUUUU old t50
i geuss ill have a look for an ae71 box and stuff then
im pritty sure im going to go smallport 4age with some kind of bike carbys
anyone know of what bike carbys would work with rather big cams?
and yes im looking on toymods rite now but im tired and will probly miss it

No reason you can't use big cams with carbs, in fact it will be easier as you won't have to worry about the factory ECU spitting the dummy at you.

Recommend going with a pair of weber 40's or solexes as opposed to bike carbs, will be alot easier to set up and adapter manifolds are readily available.
