KE70r mods, need verification & tips	Sat, 06 November 2004 17:09

Hi, i'm new here. Actually i've been browsing this forum for 2 months now to get more info and tried to read everything in billzilla.org since few months ago. I now have a basic idea on what to do but i need someone to verify what i've learn just in case i get the wrong idea. If you don't mind i'll start with my car. Background A toyota corolla DX, KE70r, 1980 model, last batch of DX before the GL came out. It has a rather square headlight, actualy its triangle but not as long as the GL. It came with a black rubber bumper instead of a metal one like the previous model (with 4 round headlight). Engine 4K, not 4K-C(according to the user manual 4K came with 9:1 com ratio while 4K-C 8.5:1). overhauled once, still running smooth, just underpowered (and the main reason i came here). Gearbox K-50. Changed 4 times, first one make strange noice, second one the same prob, third one lasted for 30 minute after installation before it crack and the whole thing drop on the road and had to install the forth one at the roadside (big embarasment ) rear axle Not very sure, but i bet its the bog warmer thing you guys talk about. The metal plate in the engine bay say it is "U2xx" something i can't remember. I'll verify it again. Things i've changed so far Actually the car is pretty much stock, and i dare to say its well taken of and has the best condition(compare to other KE70 in my hometown ). The only thing i've change is the rims, its now JRD 13" deep dish, 195/50 at the front and 215/50 at the rear. Seems to be able to corner way better than the stock. Oh ya, and one TRD badge i stick at the rear to amuse myself . Purpose of the car Near future - (Kick @$$) daily driver Not-so-near future - Daily Driver + potential drift machine. Its because a track is to be build in few years time near where i live, until now there's no track, so i wanted to learn to drift once the track is available. Not expert drifting, but just drift for fun. Goals i'm hoping to reach - at least 150rwhp - good mid range torque - little body roll - great trottle respond - as little frame work as posible (hopefully no tempering with firewall Mods in plan Engine I need 150rwhp, and good midrange torque. For what i've learn, seems like force induction is probably the best choice. I don't want to use a >300 degree racing cam on a 4AGE and make it undrivable on low RPM, and the 20v model need modification on the firewall. And you guys say the 20v isn't good value for money. If force induction is the case, should i go for turbocharge or supercharge? In the article section, the 4A-GTE article writen by Michael, said the turbine of RB20 will start boosting at 2600rpm, does that mean no boost before that? is there a turbo that will spool up faster? Some other source told me that the supercharger start pumping air at 1500rpm, which seems more attractive to me. But since it uses engine's power to turn the supercharger it produce less power. Well i'm confuse which one to choose. Help is needed. Gearbox & rear axle I initially plan to get the T50 gearbox and the T-series j-spec sprinter rear axle w/ LSD. But after reading what you guys had said, it seems like they are design for NA application and not Turbo. So i plan to get the W5x series gearbox, but somehow still a little bit confuse. Question, do all W5x series gearbox will fit into a 4ag(z/t)e? You guys only talk about the MA61, MA70 and JZA80 supra, but at where i live there is one KE70 with some "street reputation" using a GA70 supra's gearbox and rear axle. I think it might be this supra http://www.flashoptions.com/product.asp?prodID=54. Anyone know anything about a GA70 supra? friend of mine in the tuning market told me parts of a JZA80 is going to be expensive here. Well, i'll just ask a few things first, don't want to get all greedy and ask everything at once. Hope you guys can help out an oversea toyota moder. If not i'll be turning around in circles again.
