2ZZ Would this work???

[Anonymous]

Hi i have an idea and would like opinions.

If bought a turbo kit for my 2 say PE for instance, then i guess it would go straight on.

If i then decided to change to 2zz but keep the kit, would it only be a matter of manufacturing a new manifold for the turbo to sit on??

And would it work (in theory) the same as it would on a 1zz

no idea about the specifics, but no idea why you'd have problems bolting a turbo onto a 2ZZ

[Anonymous]

the reason why i say this is that the turbo conversion on a 2 is quite a good price around £2k and if all I had to do to get it to fit a 2zz would be making a manifold then I would go ahead

I'm no expert on all this turbo/2zz malarkey, but instead of going turbo THEN a 2zz swap, wouldn't it be better just to go straight for the 2zz and then sorting out the turbo for that (if you were really desperate for more power)?

I never understand this idea really, and i always think its back engineering as I would imagine you'd have to drop the compression of the 2zz to accomodate a turbo.  SO your taking one step back to take two forward if you get my drift..Plus personally I'd imagine a 2zz with turbo would be pretty akward to drive as you'd no longer have to contend with just the cam change, but also the engine coming on boost.  

I think someone on SPyderchat has done it, if i remember this topic has been covered before actually

Indeed it is  m http://www.mr2roc.co.uk/forum/viewtopic ... =2zz+turbo m

thanks but that doesnt quite cover it....... with a 1zz it is possible to take a turbo kit and bolt it on without doing anything on the engine.

So with a custom manifold running say 8 psi with water injection for cooling be just as safe to use as a 1zz

due to the highly tuned, high compression of the 2ZZ, i think it would be better suited to a supercharger.

theoretical answer yes, though depending on your custom manifold you may have to refab some piping.

problem 1.

MAF, 2zz uses a different MAF in a different diameter pipe, so your intake side may need some work.

problem 2.

ECU, you'd need either a piggyback or a standalone for a turbo (though at moderate boost you coudl argue you don't need it, me I's say you do) 1zz and 2zz need different looms on teh new ecu. your hybrid may not match either, so some work here as well.

problem 3

compression. you can turbo a 2zz without changing this but your one step closer to the knife edge.


in all honesty if a 2zz floats your boat then great. If your looking at a turbo, why bother with teh 2zz swap? It's more agro to do, more agro to insure, and a turbo 1zz can give more power than you'll ever realistically need if done right anyway.

Just out of interest, why do you want to turbo a 2ZZ rather than simply turbo the 1ZZ? If it's because of a, possibly misguided, view that you can get more power don't you think it would be easier to simply concentrate on a good turbo installation that could acheive over 200 BHP without too much hassle. Going 2ZZ offers a relatively poor performance / pound+hassle ratio. The main reason to go for this option is the fact that the engine is N/A and thus offers certain characteristics that are desirable in a pure sports car. Subsequently turboing such an installation means you will have pretty much have gone around the houses to acheive what will probably be a fairly similar nett result.

btw newboy, have impossible perfromance been in touch re their turbo?

I don't agree with any of this.  The 2ZZ pound for pound is a much better option.  Low mileage engine gearbox and ECU will only be in the region of £1600 inc.VAT, fitting is free if you're doing it yourself or should only be 3 days work.  My project took a lot longer as we had difficulties in converting it from an SMT to a Manual

2ZZ offers poor performance?  I would suggest that it is already quicker than the TTE turbo that I drove at JAE and I still have vacuum problems.  It easily hits 60 in 2nd gear with its cut out of 8500rpm.  

1ZZ with 200bhp an not too much hassle???  TTE are  going for ~185 bhp because they need a safety margin.  I know of several people who have busted crank shafts etc... because there is too much heat/pressure at this level.  Obviously Charge cooling and aquamist helps but what is the cost of these again???

You could run a 2ZZ with apexi PFC and pe turbo with an adjusted manifold gasket like my NA and still have a near flat torque curve pushing a safe 240bhp @ 7psi.  Its been done!

1ZZ would never see past 220bhp anyway without serious internal modification and that doesn't come cheap either.

If you do the breakdown of cost and power the 2ZZ easily wins on both.

check you can insure it first, engine swaps are becoming very difficult to cover.

thanks gt300   s:lol: :lol: s:lol:   thats exactly what I wanted to know

Don't get me wrong, I'm not slagging off the 2ZZ option but I still think it's going to be more hassle to change to a 2ZZ than to install a well thought out turbo kit that includes everything - something along the lines of the kit that J Haas has developed on Spyderchat, which is a bit different to kits from the likes of TTE.  At the end of the day a turbo installation is going to give you more performance because you are going to get a boat load more torque than you get with the high revving 2ZZ.

Plenty of people have gone turbo and had no such problems with busted crank shafts etc. If this was the case then I don't see that the 2ZZ would be any different in its stock form than the 1ZZ in this respect. There are plenty of people with 1ZZ turbos pushing out well over 200 BHP without serioeus internal mods. You only have to look at the celica forum to see that the 2ZZ isn't the last word in engine durability

Anyway my main point was that I couldn't see the point in doing both. If you know you're gonig to be fitting a turbo then why go to the extra expense of a 2ZZ as well. I couldn't justify the extra performance that turboing a 2ZZ would give over turboing a 1ZZ. The requirements of a highly tuned NA engine and an engine that has been turboed are different -I don't think you are going to see as much benefit from the high lift of the 2ZZ if you turbo it. The engine has to be tuned differently when turboed which negates some of the advantages that the 2ZZ offers. For the extra cost you'd be better off spending a bit more on your turbo installation on your 1ZZ, which I still beleive would yield more performance / £ than spending an extra £1600 on a 2ZZ turbo.

Just for the record I still love the idea of sticking a 2ZZ in our 2 as I like NA cars and their crisp throttle response  s8) s8)

To seriously bullet proof a 1zz for a higher boost turbo, you're talking the price of a 2zz engine anyway (see monkey wrench) but then i would imagine you could wack the boost much much higher and go much faster than the 2zz even with a low boost turbo...

...but to be honest a N/A 2zz doesn't go whoooosh ptssssst like a turbo!   s:lol: :lol: s:lol:  

Good luck with what you decide on, personally i like the idea of a 1zz turbo for myself only because i can't afford a Zonda roadster!   s:wink: :wink: s:wink:

[mph]

Pushing much more than 200bhp is waste and missing the point for a '2. Put another way, if you're increasing the power by over 60% of original spec, have you really chosen the right car/chassis?

/controversial statement for the evening   s:wink: :wink: s:wink:

[Anonymous]

you must have some serious $$$ newboy if youre seriously considering swapping for a 2ZZ then going turbo after. If you really want that much power, then i think youve bought the wrong car mate. buy a scooby or skyline or something which are already set up to cope with lots of power.

And, to be fair you dont need anymore power than around 250bhp in a little roadster, unless, you want to drag your car which the '2 wasnt really designed for anyway

your choice, your money anyway though mate. good luck with whatever route you choose...

[Anonymous]

ah, mph just slightly quicker than me!

*mental note* must be quicker in future

[Anonymous]

if i decided to go and buy an evo or skyline, where would the fun be? the whole point is to create individuality, In the last few days i have put a deposit down on a 2zz lump which should be in britain in 4 weeks. When this is installed either a HASS or P.E turbo kit will be installed at this stage i am looking at Hass, power will be???good

[Anonymous]

I'm looking forward to this actually, sometimes you've got to throw common sense out of the window (I mean that in a good way) and create some outrageous monster.

Whats the approximate price for the Hass kit complete  s:?: :?: s:?:
