My Dilemma, 4age Or 3/4kt Build.

[Trev]

Well I am at my wits deciding what to do, I have my AE82 twincam that I wanna use as a donor for the sedan (have not got the sedanas yet) but after hearing how sweet the gilmer drive sounds on Taz's rolla and always been a fan of ke30 4 doors I am thinking that I should use the twincam to complete the mrs car and get a ke30 4 door.

 

Now the plan would be to get a 4ke manifold and adapt it to have a blow through carby in it's place (reason for the 4ke manifold is to keep the inlet opposite to the turbo to keep piping neater), Turbo would be a T25 from a Z32 on a manifold I will make, I'd prefer to stick a 4k in it as I have always had a soft spot for 1300 motors and have a K50, Now my dilemma is that I like both the AE82 sedan and KE30 sedan ideas and I really can't make up my mind.

That is no question RWD ftw!!!

[B.L.Z.BUB]

+1 RWD can't go wrong.

[towe001]

But the question is - cart springs or Independent coil spring suspension ?

 

But i'm the same, i like the shape of both the '82 sedan and '30 sedan

but i'm not so much a fan of the 4age anymore.

V6 ae82 was the idea when i had the seca

[project_KE55]

KE30 for sure..

 

I'd prefer the round shape rolla over the square ae82..

 

Thats just my 2 bob anyway :jamie:

 

Oh and rear wheel driveness :blush:

 

Cheers, Mark.

Haha you know where my votes at mate. I'm a little suprised you're even considering the old boosted K considering the xKTx vs 4AG discussion we've had in years gone by. I've got no doubt though if you did go down the boosted K route you wouldn't be dissapointed though. You just got to look at the dyno print outs for some of the guys who done 4A conversions getting 60-70kw at the wheels. I got the with the old TD04-L 4ktc setup on only 8psi!! And I've never done any damage to motors running 15psi. I would it up to around 18psi for last weeks trip out to the dragway...... which would have been half my traction trouble. :blush: :lol:

 

I don't quite understand what you mean with the 4ke manifold though. How much of the 4ke mani would you use and where about would you mount the carby off it?

Personally I think the 4ke manifolds are way over rated. Given that they're not real common they sell for more than they're worth (like $500'ish compared to the $250 I paid for my 7ke mani) and then the fact that they're so restrictive (mainly the throttle body) compared to the 7ke I would never use one.

If you just plan on using a down draft weber then using a stock inlet mani with an adapter plate doesn't take up all that much room. If you mounted the turbo in much the same spot as my TD04-L then you still have enough room for the dump pipe etc. Given your fab skill maybe you would be better off just making a new inlet mani to bring the carby a bit closer to the head.

Being able to make your own ex mani is deffinately a huge advantage to you. Mine was the single most expensive item of my whole build. I don't like the think about it too much :) but mine cost me just over $700 by the time they also modified my dump pipe. I just make myself feel better by thinking that I have one of the best K series turbo exhaust manifolds in the world!!! :lol:

Do yourself a favour though and make your runners a bit bigger diametre than what mine is. Go with about the same as what most extractors are like 1"ish.

 

Also with your turbo choice, from personal experience I wouldn't use a z32 T25, they probably actually closer to an ET/EXA T2 rather than a CA/SR T25. They also have a smaller 4x bolt exhasut housing like an ET rather than the 5x bolt T25/28 flange. Given the boost response (full boost by like 3000-3500rpm) of my T25G and resulting top end restriction I imagine that the Z32 T25 would hold you back considerable. Yes it would be a low RPM torque monster but there would be no point revving it past 4500-5000rpm. If you did go with a convetional CA/SR T25 then 1, you have much nicer power range with more usable top end. 2, If you shit a turbo it'll be much easier to find a replacement (with 5x bolt flange) and 3, (this is mainly the 5x bolt dump pipe flange again) you have a lot more direct bolt in upgrades in the future should you want to get a bit more serious. Say like that GT series turbo you had at one stage. Oh just and FYI the skyline GTR (twin) T28's also have a 5 bolt flange but its different to the CA/SR flange (I can give you a pic of this) so if you used one of these (would be well matched for the 1300cc 4k flowing half of an 2600cc RB26) and then wanted to use a CA/SR one you have to change the dump pipe flange.

 

Well there's some food for though for a while. Hit me up if you've got an Q's.

 

Oh and......

and remember

Engine is not included in auction just the three pulleys ,& capscrews & BELT.

Thanks Simon, You know that my KT vs 4ag discussions was to do with a modified K to a standard 4ag tho remember :jamie:

 

With the 4ke manifold I would use the whole thing and I would mount the carby where the throttle body is mean to go.

[Taz_Rx]

Yeah I'm with ya. :jamie:

 

What like and SU?

 

I just think for what you'll have to pay for the 4ke gear and what you want to do with it, YOU could make a better flowing manifold for a 1/4 of the cost.

[philbey]

regardless of the time and money for little gain, messing with K engines in definitely great fun.

[Trev]

Yeah like an SU, Maybe a 7ke manifold could be used then.

[Johno]

GO the turbo ke30, Rwd is way more fun!

 

You've got enough 4ages to point a stick at.. :jamie: so give yourself a bit of a challenge and get the 30 :blush:

[Trev]

Only thinking about it due to my living circumstances and my AE82 twincam is sitting in my dads yard and he is whinging about it, So I can't afford to buy an 82 sedan so I am thinking of wrecking out the seca, Use all the parts I need and sell the rest like my enkei's and pay some bills and when I get back on my feet I will get a KE30, If I had an on going job I would just do both.

 

Why is everyone talking to me like I have never had a RWD before :jamie:

[Johno]

I'm only saying it becuase the corolla is the only Fwd car ive had and since driving it in the wet the other day, its just plain scary.

If i had a rwd, i'd be in heaven :jamie:

Your doing it wrong

Like, i've had my dads old '55 go from plow understeer into a massive tail slide into the bushes. And yet, the same round-about i'd take my old seca just that bit faster.

Yeah sure the old cart springs can be made to handle but out of the box independent coil spring suspension wins hands down

 

If it was me, i'd pick the '82 especially if i'd be wanting to take some runs through the twistys.

I picked my '30 cause i love the shape of it, i wanted a car to be able to go to and from work in and an old school cruiser that i could have some fun in

Wheelspin or just understeer?

Ha yeah scared, I take mine that fast that it gets into a 4 wheel drift, I shat myself the 1st time it happened and that was because I was showing off with Des (AE70) in the car.
