looking good. rebuilt time.

I just used putty on top of the piston, to measure the gap. 1 thing to watch out for is the valve springs going coil bound (spring coils touching). When going higher lift. Also under bucket Shims on the cam followers.

Waw tidy as fooook. Amazing.

Sorry about delay on the information, I'm at a very important stage of my work and it's taking all my attention. I'll get you the info required this weekend.

Yep there's not many.

I'm going a write up now.

Yep keep the 4efe loom and ECU. You just need the piggy recommended. And the 4efte engine complete.

keep me posted ill defo have a set

thanks. yeh lift on these engines is were the power is. i suspect because of the large lift on the 5ehfe cams this will affect the duratiopn slightly were did you manage to get them and if there new were from. love this: thanks.

great work as always. loving the builds going on just at present.

well well. what a race in the wet. i dont think any 1 can argue the fact that Hamilton is 1 of the greats, if not the greatest. from 6th to 1st and worked out the that the worn out intermediate tyres held temp on the drying track better. https://youtu.be/bg3v8VKEtBc near anuff every race this season Hamilton has won by at least 30sec if not more. the last race that was incredibly wet and slippy also 30sec out in front. we salute you LEWIS incredible racer, one of a kind. https://youtu.be/tKb5-5yWeCA

yeh i have the c64 lotus box in bits ATM. but its the same box as the c63 out of the corrola/celica tsport 6speed. the c64 just has a higher mph limmit with a bigger sixth gear. there is also carbon syncros available that i have purchased and will be going in. it will be the end of next year before i have this in and running but it will go in.

im very jealous. ive developed a soft spot for these. im not to keen on the body kits for these. so please keep it looking original, there so very retro/cool as foooook.

I'll do a full write up soon. Times limited just at the min with my work just at present be patient and I'll get it up. You do not need the 4efte engine loom or ecu.

Yeh mate I'll put together a full list. I think I know what your after. The piggy back ECU will wirer in straight to your original 4efe ECU. This is the best option using your better Toyota 4efe control unit on your E11. The only thing that you will need to swap over is the E11 4efe oil pump, this houses the crank position sensor.

as said by claymore me personally id get a 1998 glanza v 4efte complete with turbo (ct9b).@ 60k km it should be in great working order. to identify a ct9b turbo = on the alloy compressor housing it has no raised CT9 markings cast into the housing. the earlier ct9a does. ill put up a picture of the difference. also the ct9b has 9 blades in total on the exhaust turbine. the ct9b only came on the later glanza v engines. ct9b pictures below ct9a pictures below

the other interesting thing here about the 4efe domed piston is its weight is not evenly spread across the piston crown (imbalance). the exhaust side/half of the piston is heavier but the only piston skirt and bore wear happens on the other side (inlet)??. to me this is an obvious sign of were the combustion power is happening (crazy oddly shaped combustion chamber) the same wear is present on the 4efte engine (flat top balanced piston)

just explaining the process of which lead me to this concision on the valve springs. that was suggested to me by other that have worked on these engines in the past. also enjoying going threw your suggestions, seeing if it leads to another possible reason, as well as tidying up the threads for others in the future. im nearly always on my laptop doing work related stuff, so as i engage the topic on these cars i cant give it my full attention hence all the edits. as well as keeping it tidy. EDIT: the 7.4krpm is in relation to 4efe piston weight and deceleration Gforces, leading to th

keeping you upto date. turkey next up. what a fantastic track. its going to be a great race.

looks so so nice. shes going to the top of my great gt list in the near future i can feel it.

im not talking about the ems rpm limiter. with one of the most common garage visits being overheated engine (coolant lose) its more of a threat than you would think. regardless of why the springs are there, the fact remains they are different. i was told about this difference, and given the best reason i could see quoting the much heavier 4efe domed pistons, and im inclined to agree.

i dont think 7.4krpm is classed as screaming its tits off. which on W.O.T conditions it would be achievable should there be a hot spot in the cylinder. as for the other, wear, ok lets think so we think the springs on the 4efte are alot stronger. ive not seen any signs of heavy wear or additional wear on the 4efte heads, valve seats and cams. question? do you know the rpm point at which valve bounce happens on a 4efte?. some people have used the much stronger VW polo 6n2 valve springs in there engine builds. yep polo springs are stronger? (eco engine)

yeh I can understand that. I was told this off some of the people that build these forged engines. but to me it does make perfect sense. the 4efe pistons weight matches the g force calculations perfectly so it does make sense. safe guards. why have more springs is a better question here, this then bings you to a better conclusion. could another source of ignition allow the engine to over rev, (pre ignition) the thing I have learnt to understand about Toyota is they do things to last.

hats off brad. as always nice work. I bet that was a pain to install.

thanks for adding the picture claymore, I didn't realise you had replied. you also need to mount the inlet temp sensor into the intake manifold. this is housed in the e11 intake air filter box (only electrical 2 wire sensor in the air box) brad has a nice example of this done in his build thread on a e11 inlet
