1st gen rx7 diff fit into starlets without much trouble apparently, the rally guy sover here use them, now as for gearing, what are you using the car for? drags, circut, street or what, if you are doing drag i'd suggest going for a 4.4 or 4.5 LSD, this would mean you should max out at somewhere around 250kph
with a 4.9LSD you would max out at around 220kph but have alot more acceleration than with a 4.4 or 4.5

NZ GT Rota - a 13B monster port with the right carbie jetting and right ignition system should easily see 250+ HP if its built correctly

 

HWO I'm using the car for street/strip drag racing. I was saying that because the Starlet is such a naturally light car, and I'm making it lighter by adding fibreglass panels and whatnot, that traction and gearing would be a problem. I don't know about the gear ratios in the RX-7 gearbox...but they would have to be PRETTY long! I can't imagine around 230bhp on a 4:4...then again, we'll see.

 

a 4.4:1 will still max out at over 250kph, so with that diff you have the trap speed potential to run about 9 . something in the 1/4 mile

get the diff etc all set up then set about finding better tyres and or changing your rear spring rates and rear shocks to be able to get the power to the ground.

 

dose anyone know what set up the maz speed rotory starlet is using thats doing some real fast times on the 1/4mile???????????????????? oh yeah just a note my boss is selling his +700bhp godzilla skyline if you want a look at that or were i work go to www.cmooremotors.co.nz



just another thing boring as it mite seem to you i was at a drag racing event here in new zealand on the 1/4 mile were i saw 2 things i never thought ill ever see they were a rail rolling(crashing) at a 140mph at the end of the track and victor bray and brett stevens doing dounts in top doorslammer cars they were sooooooooooo kool the cars were set up for it but were identical to there 6sec cars

 

Getting the tyres to stick will be my biggest problem! Ok it would be a phat skid car but getting traction when racing will be the hardest thing. Short of carrying big blocks of concret or 2 big mates in the back!!

 

PoRkFeSt - what do u have planned for u'r Starlet? My 13B 6-port turbo idea is falling thru my hands....I'm looking for an EFI 13B 4-port COMPLETE engine and a 5-speed gearbox....know of anywhere or anyone I could source one from? Any help from anyone would be appreciated! Thanks!

 

Sounds to me cost would be your biggest issue. For me the issue is getting the car on the road and going from there. My starlet will be a loooooooonnnnnnnnng term project. I just want to get it running then i can work on the problems as they come up. Traction yet agian will be the biggest problem! 780 kgs with most of the weight in the front wont help. But ive sort of been talking to someone who my be able to help me with his. Ill let you know how we get on.

 

4 link rear end, progressize rate springs and adjustable shocks.

that should put power to the pavement, but remember, you cant drop the thing to the weeds and expect to be able to launch hard, to launch hard you need good weight transfer to the rear wheels, to achieve this, you may have to get it to sit hilux'd out a tad, particurly in the rear

 

HWO are u meaning put a hilux diiff in?? Ive been told to go with that or a 9".

 

Hilux it out = have it sitting standard or highish, not dropped to the weeds

 

I was planning to use either a Toyota Cressida or Celica rear....it's the 10-bolt Toyota rear....I dunno bout Hilux diffs, but Hiace and LiteAce diffs can fit in it. Those ratios will be around 4:8 and higher....which seems to be the preferred ratio to use with rotaries, at least performance ones. My main concern is being able to get the power to the ground. I'm thinking about running on 13"s as opposed to 15"s...I was saying on 13"s I could use a 4:3 or a 4:1....of course I'll be on slicks, so I should get good traction. Obviously money will be spent on good suspension (bushings and all). What do u guys think about the turbo 4-port as opposed to the 6-port? I've been told that the 4-ports are stronger than the 6-ports...and can take porting much better. Is this just heresay or...? Fill me in guys!

 

Bejeeta you need to shorten then a bit!. But theyre easy to get and nice and strong! If you blow them then you must have one mean car!!!!

 

PoRkFeSt - they're pretty common place around here. I think I'll get one and get a 4:8 diff or a 4:3. I would like to buy an LSD for it eventually but for the meantime I'll just weld-up the spider gears!

 

hilux diffs are good but they are drum brake if you are like me and like many others you would like disc brakes so i would go for the other toyota diffs or even a nissan diff out of a silvia like i always say though its just trial and error and if theres enough will you will make it fit

 

I would like a rear with disc brakes...I was even looking at some Ford rears! But there are not much RWD cars with disc brakes scrapping here in Barbados...it even seems that all the AE86 Corollas we had down here disappeared off the face of the earth! I don't mind the drums though....but we'll see how it works out.

 

sylvia diff could be interesting considering most of them are independant rear suspension, if you were getting that serious that you are gonna convert it to IRS, then put either FC or FD **** end in it. Putting discs onto a hilux diff is fairly easy, hilux and landcruiser diffs are very similar and a lot of guys who build up 4wd vehicles run crusing diffs and put subuaru leone brakes onto them

 

converting to IRS aint that bad build a sub frame with the IRS bolted onto it then mount it to the bottom of the car.people over here in new zealand do it all the time infact quite a famous car having IRS built onto it is a 20b pp mazda familla which was front wheel drive converted to rear wheel drive with IRS so it can be done,to see more on it go to www.badrotor.co.nz

 

I have access to an old Nissan Laurel diff, however it is not discs, it's drums. Does anyone have any info on these diffs? What are the ratios for these diffs?

 

Who ever told you you cant drift a starlet is out of there mind. Go to youtube and type in Starlet Drift. Its the first one I would just give you the link but this forum wont let me cause this is my first post.


Anyways.. Im 18 and I have an 82 Starlet that I just finished workin on last summer. I built it from the ground up with my dad and is my first car. I painted it and did all the body work myself. It has a stock engine and tranny and I want to make it faster. So i was wondering which would in fact be the easiest way. Thanks and let me know.

Would show you a picture but once again the forum will not let me..

 

short wheelbase makes drifting easier, not harder

Whoever said that is an idiot

there's youtube video of miatas, etc drifting all the time

ALSO
there's video of KEI trucks drifting, shortest wheelbase of anything there is probably.

I've drifted quads even, wheelbase of like 4 feet.

 

the way i have seen most 12A and 13B swaps into starlets, use the front cover mounting points from the 12A and the 13B GSL-SE 1st gens bolted to the frame

 

the way to do this swap is to use a GLS-SE front cover,pan and oil pick up tube.Turn the GLS-SE pan and turn it around so that way it clear the subframe,swaybar on the starlet,position the engine as far and low as you can(motor mounts should be place before the front wheels not after the front wheels)you need to bang the firewall in order to clear the clutch slave and tranny(dont cut the floor it can be done without doing it)now the tranny needs to get modified because the shifter is all the way on the back seat,the way to do this is to move the shifter forward on the actual tranny(you need to get a shop that knows what are they doing in order to get this mod done to the tranny)and while the tranny is apart get the third gear sincro mod done so third gear goes in easy,run a stock turbo 2 ignition sistem(is really good)and for rear end the celica rear goes in without a lot of mods needed

 

another thing is that the stock turbo and manifold wont clear so you need to get something custom.
