they are pretty loud atm wot dude.I have mine rerouted back into the silencer so its resonable.

ttt

the funny thing is gainzy is that that engine had 180 over all four. it was a superbly tight little bugga !!!!!

doesnt burn oil whatsoever :-D pistons were in superb order last year when I did headgasket.

such a wicked set of wheels.

yes all myself for sure. I built a forged engine in 2010 for my gt turbo and it was perfect. love working on me own car.its a pleasure.

yeah the best step is timing check.then after that if its ok then a leakdown test will be done on friday. :-D if I wuda been at 160 I would still be doing all this. I like things to be perfect and in order.

yeah my car has fully synthetic mobil oil every four thousand miles,is ALWAYS warmed up and cooled down. I cant see rings wearing from 180 down to 150psi in two years being treated so well.I just cant.

no no no.lol I have taken all comments into consideration,I have read on a few occasions online that toyota handbook says about 150 being service limit. the cars running lovely and always has done.just needs a freshen up I guess. theres more investigating to be done before any rebuild or disassembly. :-D pmsl

cheers adam.I am with you. its gotta be sorted.the service limits there for good reason I guess. whatever happens I will fix in within the next few weeks. the fact is its not the compression its meant to have and I will sort it. as yes they are all spot on 150psi on all four,no variation

yeah cheers for advice ,good shout. thanks for all ure help .

its a proper fte matey,yeah tiz on service limit headgasket I have done as a precaution last year and stocker went on to replace the stocker headgasket. defo all standard inside man as I say above when I bought engine it was 180 over all four as I did the test personally. theres no way the rings have gone in two years of me over maintaining the car and using the best oil. gotta be up top or timing of a tooth im sure.

all the same readings ,150 psi

look it up. brass vacuum restrictor nout to do with ure pcv valve which fyi you shud remive as they do not help the crankcase pressures !!!!

yeah starter and battery are in good order.I have very good voltages also etc. as for the getting it mapped and it not being that bad dyno result,the cars compression is at the limit or service so needs action and the compression being so low is going to cause power loss. it should be a good 210 plus for a td04L @1bar with a fcd. its only because of this dyno run the poor power has come to my attention and I have looked into it and found a fault. thanks for comments. :-D

yeah I knew it was around 150 ish,but for me its gotta be bang on and right so I am going to do something about it. yeah I am looking forward to seeing what the leakdown shows adam.as for the leakage yeah I read ideally it really shoukd be under 14%. thanks matey :-D

yes possibly and most likely turbo my friend

makesure it has a brass restrictor in t piece or sumwere at least

thanks for the replys dan.much appreciated. to give u an idea,when I bought the engine two years ago it was 180 over all four.it was perfect. its had oil change every 4 thousand miles without fail with mobil fully sythentic, i have had the cambelt of around 4/5 times since doin various things. it runs beautifully well,starts on the button hot or cold,new entire ignition system,tps set correctly,timings 10°, afrs are bang on and always have been. and yes I totally agree with you to do checks and leakdowns before rebuilding. timing belt is next up to check. thanks again for your time :-D M

just spoke to a mechanic mate of mine and he says its HUGELY unlikely that piston rings on all four cylinders have gone simultaneously. more than likely to be timing and or valves.

so after my dyno run with not to great results I have done a compression test which shows bang on 150 over all four so looks like somerhings worn out. these engines are meant to have 175 stock and I know 150 is service limit so looks like time for rebuild of some sort. I am going to do a leak down test this week to see what exactly is failing . I take it this would ve my cuase of 180bhp on a td04 at a bar instead of the 220bhp it should definatley be.??

what is the plan for the new turbo above ??

man thats crazy.silly question but is that metal or rubber ? pretty mad dude

bloody good price there mate.glws.
