Hoping to forge my 4e soon and map it on a tongs hybrid with an emu for now till I get a big turbo.
Just woundering is there many lads using forged gt or glanzas daily or any lads with big millage forged engine have you had any problems what are they like reliability wise. I will be using standard head and inlet man. Have this up on toc as wel but thought there would be more UK lads using forged everyday

I ran my forged engine daily without any issues. So long as it's soundly built you should have no issues :)

That is a savage build mate have encountered any problems over the course of this millage. I will just be using my standard old head with new stem seals but I won't be going over 300bhp with it

A forged engine will last however long you want it too. Maintenance is key, aswell as driving style and mapping.

I sold my forged 4e with about 35k on it, well used and abused but always maintained. And that was running 270 hp daily.
As far as i know its still running in the lads car that bought it.

Forged motors dont need rebuilt if there built properly in the first place, motors that need rebuilt are usualy built shite to start with.

If your using acl bearings then they are supposed to be changed every 20000 miles.
I will be using stock toyota bearings on my next forged build.

Thats 20000 of full load all the time like in race engines though? If the engine is built properly (clearences etc) they will last the same as stock if not longer saying they can take way more abuse ie bigger loads for a longer time.

Thanks lads it's all helping keep Your comments and advice coming. I am just waiting to get a prices back on forged parts and should be starting the build soon so you Wil prob see more threads up ha what boost should I run it in on my hybrid .5 be okay? And what should I set my fpr to for running in engine.

best thing is to get it to a tuner first thing (perf. on a trailer) to have it set up. then drive about 500km alternating between 2500rpm and 3000rpm on the highway.
don;t let it idle straight after the rebuild. she needs to run a little hotter in order for all the new parts to get the right wear so everything seals propperly and the clearances are good. if you let it idle for too long after the build the piston rings won't seat propperly and you might be left with slight compression loss and the engine can burn oil slipping past the rings.

bear in mind that this is mainly for a race spec engine but i'd say do it the race spec way to be sure :)

But it can't be set up on the rollers until it's ran in can it. Is it ok to let these engines idle after it's ran in and mapped say to let it worm up in the morning etc or would it be good idea to set it at high idle say 1500rpm

It will need setting up with a base map when built, use 10w40 mineral oil through the running process and not of the synthetic stuff until that period is complete

A lot of tuners can do the running in process on the dyno for you its a good way to run them in as you can vary the load and stuff then just change the oil and tune it fully.

Forging an engine will not really make much difference to it as a daily driver, it will need more maintenance as the lads say. Tuning it to near the 300 mark will make a difference, dont expect it to drive like the stock set up or like a 300 bhp Evo.

But couldn't I just run low boost for daily and turn it up for drag and track us. What turbo wouldn't be good for 250-300bhp with minimal lag a good evolution td04 or something else

I run a TD04 on my forged motor 278bhp and have 4 setting on the Boost controller,.7,1.0, 1.2, 1.4 bar i tend to run round on 1.0 and 1.2 bar, for the road that is more than enough, you need to be thinking about boost control,LSD and better brakes to go with the forged motor

The hybrid's run near 290-300 but do you need it on the road, i would sooner have it lower down and more torque again all down to set up and tuner
