This is clean, and about to be cleaner. Fresh paint, you really can't beat it.

Does the car run.

It would be good to get a data sharing section up. I'm reluctant to put data logs and data logged/calculated onto the build thread because it's not most people's cup of tea. But for the ones ho are interested it could transform the way these cars are seen as well as making 200hp+ reliable, easy reachable 4efe't, 250hp none forged 4efte At present if I mention the 4efte to people in the JDM know. They look and laff and say wait for it to blow up. Threw Popular you tube starlet tunning channels I fully understand why this view is taken (poor little cars). As well as 100hp n/a.

Haha, yes. I was waiting for you to bring the piggy back up. Very very true a 1meter pipe to this sensor makes me shudder inside. As well as all the inline t offs I see on people's builds going to all sort of devices even multiple gagets. I had my fingures crossed. I was thinking come on lads. ho will get to the offset. Especially as alot of piggy backs do use there map sensor for engine loading. I knew you would hit it on the head. You can see every system no matter how small. can be tunned and sharpend up. Every little thing. This is a 30 year old production line

Because I'm not running 4x egt sensors on each cylinder I'm using the hottest cylinder and the spark plug to work out temperature coefficient on each cylinder. I'm not with the results at the minute.

Thanks very much. I've been told about this and yourself being very experienced on these. I'm literally in the process of designing the breather system and your name keeps coming up. FATE has happened

Yep this also damps/delays the map signal. (Map sensor filter) and the longer and wider id of the connecting pipe. This becomes a volume of stored pressure, so size (length and diameter) are a big factor here. The aim is to read direct manifold pressure. I was referring to the fuel injection 4 cylinder comment with the picture above. To answer your thoughts on the antisurge fuel rail valve. Fuel pressure pulses can be seen on a electrical fuel pressure sensor placed in the rail. Made even worse when the low output alternator when placed under high load. Brad ho has the fantas

Any updates? I'm just here to borrow a picture from you. As well as see how you are doing.

The difference is anuff for a colder spark plug to be run in cylinder 1, compared to the rest. With this engine being a front facing exhaust manifold design, I'm getting the egt sensor as close to the exhaust head outlet as possible to get a very accurate cylinder reading. These are a thin mild steel manifold.

Yeh the corrola manifold is a great bit of kit, and definitely a fix for 1 of the main engine/cylinder power balance issues. Another interesting issues is the low kv output of the standard internal ignition coil, using uneven length leads this affects flame propergation and cylinder timing, especially when boost pressure is introduced. As you have mentioned if a pipe is used on the map sensor it dampens/delays the signal. This is the same on all manifolds and the longer the pipe the more this effect. if you then introduced t joints and things like piggy back ECU or bov or gauges things g

Yeh that's what I'm getting I've got a set of 5ehfe cams here off the acis manifold model. I might be wrong but was it yourself that designed a inclosed engine breather system using 3x check valves on a catch can.

It's mainly because cylinder 1 runs the hottest. the inlet design (position of cylinder 1 in relation to the throttle), and fuel rail. with cylinder 1 also the last injector on the rail. There's a possible link as to why this cylinder runs the hottest. Also with it running the hottest im foucing onit. Using cast pistons this cylinder is the 1 to watch (expansion in the bore)

Nice the later corrola inlet manifold also really affects low-end rpm torque and spool. I'm thinking a slightly different setup for the short courses. Tubular inlet and 4efe cam?? Could be a kick ass combo. Easy swapin.

These are old pictures I'm just sorting threw. They are piling up on me. The bay and car look totally different now. (Tidy & clean). Yeh I'm rooting out all them errors. Like fuel burning in the exhaust giving false O2 readings and increasing egt and cylinder temps (overfueling) Also plotting egt against turbo spool up. A very handy tip is to also plot it against spark kv duration and dwell gives a great picture of cylinder temps and pressure. Again for overfueling !!! Safety as thy say. Even the old factory fuel filter is still in this picture. To a

Thanks. Don't rush these 4efe with selective mods can be very impressive. And reach 1.6ltr power levels quite easily. I've got lots of old photos here I'm just working threw new to get up on the build thread

Older turbo kit that came with the car. (Just alittle squabby) against new kit setup This was as all the sensors was being positioned and wiring installed. 2x egt. Intake temp repositioned. 2x nock monitoring sensors. Wide band 02 Repositioned original O2 sensor. Repositioned map sensor close to throttle to achieve a 1 to throttle against map response. Pictures to follow Fuel pressure sensor. Low coolant level warning sensor. Battery relocation Twin fuel pump relay setup and wiring.

Nice build do you know about the difference between the 4efe and 4efte inlet cam??. Keep the great work coming watching with great interest. The higher rpm torque the 4efte and early power 4efe gen1 can produce is really incredible for a 1.3ltr engine. Thy did use a smaller throttle body I have 1 here. This was to access and control low rpm inlet gas speeds, allowing the power manifold reach its desired power level. I'm quite handy at reading Dyno graphs if you guys ever require another opinion.

Very much appreciated. I was going to get it repainted BMW sunset orange but I think I will get this 1 wrapped to have some track fun, and a 5e build I'm doing painted sunset orange.

TRD the centre of Japan's racing hart. The same stereo as me. These do clean up well. Keep them updates coming

Great to see some of these drivers/pilots reaching new highs after struggling in F1.

Just found your build now. Nice start and colour. Talk us threw your plans, have a good look threw the owners builds there are some exceptional example's. What model is this.

Welcome along there does seem to be quite afew northwest owners active, but these are older lads with accomplished skills, from what I can see probably with young family's and not alot of time on there hands. Get a build thread going.

The emb, unichip or aem is a good ECU for the targeted power levels. The software is ready available for emb and aem units. The emb is getting a bit data now. Are you mapping it yourself?. I've been told tunning developments are one of the best around and are familiar with the emb unit.

Yeh it was a let down. I can't even imagine having to navigate that course in them conditions.

Thanks I'm looking for a set now.
