So it's very difficult to locate a kit or indeed a converted car .

Personally have experience with both Honda B18C(Del Sol conversion) and K units in a 2011 CTR - awesome engines, but not a huge amount of torque, thus essential to be in the right gear or else(probably similar to the 2zz) 

I was close to writing/posing a question to you all last night

What are the most cost-effective options to achieve 190-200bhp in a '2' + itemise the pros/cons of the driving characteristics of each of the avenues....I realise this is hijacking the thread somewhat, so tell me to b.off if needs be

You already own it!  get the superblue bugs ironed out and away you go

2zz is probably cheapest to get 180ish and as long as you can find a good engine and dont mind having to stay above 6000prm to make progress its a proven option.

Turbo is prob next cheapest but if you cant do work yourself it gets expensive and all depends how far you want to to.

2zz is only cheaper if you do the work yourself.
Last time I had a turbo kit fitted it was like 3k all in.

Yes maybe but 2zz is still cheapest option i think and easiest one to diy, or normal/non-specialist garage capable as  2zz is basically a bolt in job with only custom parts required providing you get the ecu etc are the exhaust and 1 engine mount both which are available ready to fit, little bit of wiring for the lift but again plug and play parts are available for that, turbo setup is much more involved as you know hence more cost unless your lucky to find a complete TTE kit of course but hens teeth are more common and stock kit isnt that good, good chance it will be tired as well but in good order makes a reasonable road only setup

Gearbox is another issue if going 2zz and wanting to retain LSD, the celica 2zz close ratio box is needed to keep the 2zz in lift but it doesnt have LSD, if just a road car maybe not so much of an issue for most who probably never need a LSD, however if wanting to retain the LSD it needs to be swapped over from the MR2 box or one sourced to fit into Celica box. There are some jobs to do on linkages to fit celica box into back of MR2 but nothing too tricky.

Ive looked at 2zz swapping several times and if my car was pure track i might consider it, however as its mainly road use and i do sprint events which require good response and wider powerband ive never gone down the 2zz route, maybe one day

Interesting reading. I've been reading up on turbo installs since someone on FB said they were getting 240whp/270fwbhp on stock internals, 13psi dropping to 10psi @ 6krpm. Bold claims. I always thought the SP-alike figures were ambitious tbh but it seems there are a few out nice builds there with reasonable evidence of the claimed power. Although I bet there are loads of back-street garage or home builds that are claiming big power when they're really wheezing away like an asthmatic dog.

Turbos aren't my thing tbh, I prefer the delivery, noise and emotion of a sweet N/A (125bhp/L tuned N/A = dreams). But I can see the appeal when looking at the cost vs benefit (power). Makes sense for daily drivers that like a bit of grunt or for motorsports/out-and-out performance.

I'll follow this build with added interest now

Everyone who claims big numbers never seems to hang around long.

I've put more miles on an Sp240 kit than most. Its more than quick enough and you wouldn't want to push that setup any harder. Asthmatic intercooler and piggyback ecu with such a small turbo can't be pushed any harder.


My current car is 255 whp and its no quicker on a tight twisty b road than any other 2.
In fact sometimes it's less fun because you can only use 50% of the power it offers.

This is how we felt about the SP240.

With the standalone it was better (although it still needed a fair bit of tweaking to make it as "oem" as sp240) but the power delivery was much more controlled, allowing the mr2-like drive (foot down out of corner) without the fear of the back swinging out. Personal choice on our side as I know most want that wallop of torque that a turbo delivers. 
This is the benefit of modern standalone and I suspect how we see setups achieving higher HP figures these days - the ability to control torque delivery to spare the gearbox.

This is why I'm absolutely more sold on something like C's SC car. It seems the. Mr2 just thrives off linear power delivery.
Or a V6. 

But... I still stand by the fact that @mikek 's Stg2 2zz is the best mr2 I've driven for power delivery ever. Loved it.

Was a well sorted car that one.
Best example of the NA 2zz if experienced.
Tbh your sp240 wasn't right and the way you had it mapped on the Ecumaster was a little strange.

It certainly wasn't right. That's for sure.

The mapping also left much to be desired, but I was just mega grateful it wasn't trying to blow itself up kill us anymore
