Definitely my starlet friend we share a common interest which I'm very much enjoying. All the systems employed are either common to modern day engines or past technology seemingly forgotten mainly because of high and higher hp targets or modern day turbo tech no longer requiring it. With such a basic older turbo and road hp requirements target mph times this system become eligible for us to use/test.

I've received these today. It's going to be a pain to Keep the track toeing hook looking like this. Only to be fitted for track with the reduced drag bumpers.

Put it this way what ever positive pressure (boost pressure) the seals can withstand on both compressor and exhaust turbine (exhaust back pressures, these are generally higher) the seals can equally take the opposite (negative) pressures. There is of course oil pressures to consider. I can see how you came to the answer you did. I've not explained the engine breather system. This is setup to maintain a set relatively constant negative pressure to stop piston double pumping (know as engine parasitic losses) and promote piston ring seal. Lol ive left this off here for now as I can im

It's not fully closed. the throttle control arm will be setup to control negative pressure. How much negative pressure are you thinking about. You do realise the range of both positive and negative pressures, Do you understand engine throttle and manifold pressure. The engine breather will also be in the line between the turbo and pre turbo throttle. Answer to your edit: To answer your edit: that's if I'm on a straight strip run or quarter mile. Track and street or different altogether with a variation of widths and corner angles (exactly why this system was

Now we are talking what model and year are these from, I know Brad on here is running Celica dual acting caliper possible 4 pots, I'm not to sure. I'll look on his MK1 build. Brad is quite but really very clued up. I think he's even running a gto bigger master cylinder.

Your quite correct on the throttle body before the turbo. Gordini first introduced these on the Renault engine in the late 1980s F1 era to reduce turbo lag. It simple removes load/air from the compressor wheel allowing it to free spin. As the throttle opens slowly it increases air velocity into the compressor inlet. Massively mighty and equally impressive BMW 1.5 four cylinder 1980s F1 era 1500hp turbo engine sporting the before throttle body as seen. Also the V6 1.5 1500hp Renault gordini engine 1980s F1 also Other engines: honda & Porsche tag turbos also ran throttle bo

So so nice.

These came yesterday, new big end shells. after it's been dynoed and I've got the engine oil results back from being tested. These and the oil cooler will be fitted.

A good friend of mine has used the old zisco manifold and made a jig for this a new manifold/turbo kit. The turbo has evolved again this time using a td05 20g antisurge compressor housing modified to fit the 13t hybrid. I could not trust the surge I was getting with the 4e skinny rods. This should also pump more volume of air but at a smoother rate in the rpm band. The old 1 was good just heavy corrosion. He is fitting this new kit to car whilst I'm away. I'm currently making the pre turbo throttle body. Made up of 2x back to back 4e series throttle bodi

Now we are talking. All looking good.

Nice build.

No worries. I recon most of these now will have seized idle control gates. These cars/system is so so basic it's fun to just work out how it runs, very simply done. Enjoy.

I'll order a set now thanks dutchie I've been told on the corolla owners forum that some early 1998+ avensice brakes fit the corrolla calipers also both twin and single pots I'm getting full info soon, there's something about getting custom brake lines made thw.

Minor heat cracks Looking good. Nice stoping power there what size are them discs.

Thanks The caliper piston travel I'm getting needs the thicker discs I recon. I'm worried about the piston travel at max pad wear. The discs I ordered do not fit they were 5 stud Corsa D discs, But the MR2 front calipers fit to the corrola pad carriers with a slight grind/mod (this can be seen in 2nd pic on this topic). I've ordered some spigot rings also from custom spigot rings on the internet. I'll put up the full mod when I get the discs and spigot rings. Thanks guys the MR2 calipers are common and can be still bought new/reconed or 2nd hand. So can the corrola pad carrie

Yep Here's the throttles I have off the 4e engine The top 1 smaller butterfly is off the ep80 gi and COROLLA 1st gen used with the 4efte inlet manifold. More pictures to come I'll strip them down. The 1st gen has an idle adjustment screw on the top right side like on the turbo throttle. The 2 different idle control valves on the starlet. Both idle valves are seized solid in the alloy housing. The right 1 has been modified by someone you can see the steel putty coming out of the idle valve inlet. They must have adjusted the t

Is the throttle body mucky in side. Would you be interested in setting up the tps and throttle butterfly. You will need a multimeter we can compare readings from the air temp sensor& coolant temp sensor engine cold. What year is yours I've got 2x Different idle control valves here Infront of me on 2x Toyota e series engines. I think 1 is off the 5e paseo but I was told the paseo has a 4 pin tps but these are 3pin With 2x different idle control valve setups.

Big help it looks like there are afew calipers that fit the corrola carriers with alittle moding. What kind of travel have you got on the brake peddle with these, how much free play.

Your welcome. Big fan of your build. Im striping an early 4efte head at weekend to port and polish it. If your interested in the valve springs.

It sounds like it could be the throttle stop setup. This is the Allen keyed adjusting screw on the throttle arm at rest position. Did you say it's a different throttle body. Also there is the intake air temp sensor and coolant temp sensor these adjust fueling if 1 is faulty if will fuel more but because of the large veriation of the sensors readout the ECU does not see a fault.

Yeh 2 of the best caps right there. Yeh I'm having the same issues. My email has been verified also.

Great thread. There's some lads and lady's out there that really love starlets. What models were available??. I have the cd full electrical model with sun roof and adjustable steering column.

The best cap on the market for these seems to be the cosworth cap from demon tweeks. Most of the track starlets run this cap. It's the cap I'm running. I also run a restrictor cap/plate in the top hose to keep the block pressure up and in the block. When running higher cap pressures be mindful of the plastic radiators and factory old spring type hose clips!!!!. This area of the engine was the first thing I was warned about when becoming interested in the vehicle. As well as being told this is the main reason of engine failure low block pressure overheating internals, especially cast allo

Urmm nothing mad about it. It's quite simple it's the same system, you just use the radiator to help maintain block pressure. This is how most other engine manufactures work. I take it you aren't aware of the pressure cap problems at high rpm and temp. (Track action). A very valid point of filling the system. I always use pressure\vacum to fill the system and test for leaks, but as you have pointed out if you fill by hand there is a potential for an air lock if filled in a hurry and not bled threw. The coolant flows from The water pump to the engine block, threw the blo

Thank you for any information, any wear information off an engine of this age is most valuable, most do not last or get stripped for parts. I'm strictly interested in the vehicle and technical side. I'm not here to cause trouble any information gained I'll keep private. I'm just going to have a read back threw your build at power levels, and service information. As said you work fast she nearly out.
