kpr's starlet

[Roman]

New VVTI install looks awesome. 

Reading first page of this thread, posted in 2007 - when you said you've had the car for a couple of years. 

Must be coming up to nearly 20 years with this car!

[kpr]

Yeah back when you could buy a kp starlet with 4age and t50 for 1500 bucks haha

[Roman]

Wow! 

Probably cant get a working T50 for that anymore haha

20v 4age at that too - oh the shame

[kpr]

I have no idea what happened to that engine.  seems ive owned 3 20v's in my life,  for shame.   although only ones made it out alive

[Truenotch]

It's great to see the turd still making great power while making great smoke. Makes me wonder how many compressions are going missing at the moment. 

 What's your end game? Bigger cams?

We need a video of the blue plumes from outside the back of the shed

I tested it with a crappy supercheap compression tester awhile back  before put the trd head gasket on it.   130 , 130, 100, 130.     can only assume its worse now.  with factory cams, no body home on 3 at idle.  with the bigger cams idles like junk anyway so easy to ignore.

end game is to build the long rod engine properly.  with the head off the 150kw engine along with vvti.   around atlantic 4age numbers  but with a massive power band and reliable is the goal.  looks doable at this stage

turd will be coming out soon,   and in the meantime will be putting 150kw engine back in.  probably put a vvti setup on it also

Too many bits of pistons and rings coming out the exhaust, might break my camera

Are you sure you want to run that clutch plate on a street car?

Unsprung clutches are generally not advised for street driving as the start/stop loosens the rivets holding the clutch plate to the hub.

And they work the input shaft wearing it.

So the manufacturer I talked to only advised using it for drag cars.

On the flip side,

• your right it should help the synchro's due to the weight
• my mechanic runs unsprung on all their rally cars and has no issues, but they also run sequentials most of the time.

True, true

^  this  

Probably not ideal.  But if it changes gears, not worried if it doesn't last very long. considering the amount of use the car gets

[mjrstar]

Can get 3 puck with sprung centre next time maybe? 

I just ended up down a rabbit hole drooling over exedy carbon r clutch. I reckon you could do a carbon conversion if you find something the correct diameter. Assuming there isn't an off the shelf option.

I ran an un-sprung centre in the EP71 behind the first 4agte setup which made 195kw or so. It wasn't too bad to drive on the street once you got used to it and it held all the abuse I could hurl at it on the quarter mile.  One private day I managed to get 22 runs in across the day, sometimes swinging straight back onto the track from the return lane.  The clutch slipped right on the last run of the day but it was absolutely steaming with heat which was probably the cause of death.  The plate ended up with a bend in it and you can see how much heat it took.  The rivets were loose.  Poor clutch. Replaced it with the Exedy 3puk shown above with the shiney cover.  Its held multiple 11.8sec runs and is pretty good cruising around too.

^ That's because it was a 16v back then.   20v  not enough jam to break current one

Will see how it goes.  no big drama to swap to something else. was just the easiest and cheapest way to pull weight out of it. 

 

almost pulled trigger on one of these,but cheaped out.    has sprung center single plate

 

 

[shrike]

Sorry, remind me what comp ratio the latest motor is at?

[kpr]

should be about 12.6:1 .  but have never measured super accurate.

Its running 11.3:1 pistons,   with head skim and thin gasket to up compression and tighten squish.  not a fan of the pointy dome pistons available for them.

it'll make those numbers on 95 pump gas. because "street car"

[Dudley]

Nice that your starting to get into 4k with 3/4 racecam power territory 

[kpr]

still got awhile to go before make those numbers uce

[Dudley]

That’s why I said starting, once you pick up 30kw more then we can talk Turkey toko

[piazzanoob]

shit that thing makes good power for a 4age 

must mean it will be ready for OS drags in December?
