Engine dead - options please???

Each to there own indeed.
Sometimes it's not where your going but the journey that's important.
Hell for 5k I would probably have 300+ bhp 1zz turbo but that's just me.

I agree with the first two comments Scott, but you'd need a bit more than £5k for that kind of package  s:wink: :wink: s:wink:

It's no secret that the T400X has had a preposterous amount of money sunk into it - enough to buy a GT3 - but the journey has been much more fun! (Oh and it's faster than the Porsche   s:lol: :lol: s:lol:  )[/quote]

I never said how long it would make 300bhp for Matt.   s:wink: :wink: s:wink:  
Point taken however.

As matt did the tuned 1zz will make as much power but actually more torque. It is also and engine that you don't have to scream everywhere to get it to move as it will always just get up and go. And if people really want to go why bother put a better engine in then why go 2zz when the 2gr lump makes over 300bhp stock!!! Tommy stick with what your doing, i can promise you it will be problems on the way but will be worth it. Also for others info ive sunk over £10k into my engine alone. Guess i should of just bought a lotus.

It'll offer a better torque curve than a cammed 190bhp 1zz would. Also, I'd doubt that a 1zz with all those uprated parts would be as reliable as a nicely worn in 2zz anyway, there always tends to be a weak link somewhere along the way when the tuning gets serious.

I doubt the 2zz would make more torque - it has a shorter stroke.
This is not "tuning getting serious" - this is making the best n/a version of the engine that you can.  Until you get to forced induction you'll be nowhere near any weak links of the engine.

I'd be interested to see what torque a 1zz running those stage 2 cams produces compared to a 2zz

thanks for the encouragement lads nice to know some people share my izz love  s:) s:)

well I would be more than happy to post the results once its all sorted might be while as it needs running in and putting back together first   s:) s:)

from my understanding and with speaking to people who have built these engines up it should have a better torque cruve than a 2zz but time will tell

it shouldn't have to many weak points as someone said, and the tuning isn't that radical, basically removed the dodgy pistons for 79.5 12:1 wiseco jobs and rebuild the bottom end which high spec bearings all new pumps etc and had the flywheel crank pistons and rods balanced, then cams head work etc, I wont be reving its nuts off maybe raise the rpm to 7.5 but that's it its nothing radical really so should be a good strong engine once mapped in the 180bhp/190bhp I would be happy with that

it might be worth pointing out that this is a joint project with a good mate of mine so we have split all the cost which has made life easier

cheers tommy

Hi chaps just to give an update on this, I hate it when people ask advice and never post their conclusions!

I was contacted by a fellow forum member who had done a 2zz swap himself and offered to help me out. So that's the route I'm currently on with   s:) s:)  

I'd like to thank Matt for his time and advice, he knows his stuff and I'll certainly want to untilise his services in future. My main issue was I don't tend to keep my cars very long and although £1300 1zz rebuild is a great price considering that would probably sort the engine for life, it's the next owner who would be getting most of the benefit and not me!

Great choice, you won't regret it.  s:wink: :wink: s:wink:

People here seem to think 2zz are much more reliable? Is that actually the case?

AFAIK it's only the pre-face lift 1ZZ's that had any sort of reliability issues. From what I have seen and read the post-facelift 1ZZ and 2ZZ have been generally very good.

It's horses for courses, do you want a new engine, or a faster old engine?



Personally I think the 2ZZ is a fantastic engine. Makes me laugh every time it hit's 'lift'. Really can't wait to be slotting it into an MR2.
