utter blasphemy, talking of sticking a Honda engine in a Toyota. but if you wanted to then id much rather have the F20C engine from an S2000 than a K20.

dont know of anyone doing such a swap, i do know of someone who has put an F20C in the front of an AE86 though. dont know of anywhere on the internet where its published with any pictures or details of the swap, there are a few videos of the car itself driving around on youtube though

Installing a Honduh engine in a Toyota = eternal burning afterlife in hell

more importantly though, i dought the dollar to hp ratio is that good, honda engines are really only good because people make expensive bolt-ons for them, other then that i see no real reason for this

Can't deny that the K20 is better, performance-wise, compared to what Toyota has to offer right now for an I4, though. I've seen a flow bench test of a stock K20 (forget which one) and a port and polished 2ZZ and the K20 still outflowed it. I'm no fan of Honda but the K20 is one impressive engine.

yeah but why would it be sooooo hard to port and polish a toyota head? that sounds alot easier then all the money and time involved in swapping

plus i'd still like to see actual numbers on K20s, i've seen alot of them blow up with mild tuning, so i'm not really confident in their strength even if their head design is good, i did once have a friend with a 270whp K24 (acura TSX motor) in a RSX, however he had spent probably near 10 grand and was running alcohol injection(or some sort of injection) and it still blew up, presumably because of a oil gear none the less, and its worth keeping in mind he only bought the K24 because he blew up his K20

i specifically remember driving his car when it was stock and it giving me a very similar impression to a slightly bigger version of a 2zz, just in a lighter car (2zz car ive driven is my dads 03 Vibe GT, for reference)



on a side note, i do like that bodykit on the spyder, knock off the stickers, paint the carbon fibre, and get a milder wing and you'd be set :)

those arent the car i have seen, but they are some others that have had it done. there are quite a few AE86's around with Honda engines. the one i know of is a drift car in Ireland (i think) but the work was done in England

Why an F20? Or F22 for that matter? So far, I haven't seen any F2x n/a modified top a K20 n/a hp or tq wise.
thats solely down to the popularity of the K20 engine though. The F20c is in a car that sells maybe 1 to 100 compared to the cars featuring the K20 engines, and more people modify the K20 than the F20c given that the S2000 (at least in the UK anyway) tends to be owned more by middle aged people, whilst the Civic Type-R is more commonly owned by younger people who modify cars

the F20c is probably the best designed production inline-4 EVER, just everything about it is awesome. its the reason it is one of the highest revving standard car engines ever, and also why it makes more bhp/litre than any other affordable NA car on the market (or at least did when it was new, not sure if anyone else has beaten it now)

there is loads of power to be had from them NA, FAR more than from the K-series, its just a question of people finding the power. there are nowhere near as many places that know how to get as much power out of them, and there are less parts available. its not like the K-series engine is cheap and easy to tune though, there are lots of parts available, but as has been said by someone else, its still an expensive game

personally id want to keep it all Toyota and would go for a 2ZZ-GE, but they arent as tuneable as the Honda engines off the shelf, it depends on how involved you want to get with it, or if youd even want lots more power. the AW11 chassis would struggle a LOT past 200bhp IMO (there are quite a few turbocharged ones running 250bhp+ though) without extensive modification to the chassis (in terms of actual chassis strength, but more importantly the suspension) and 200bhp normally aspirated would make it an incredibly fun and enjoyable car

Yep, the 2ZZ-GE or the lesser tuned MRS engine still seems a good choice for the AW11, put it on throttle bodies if you wont to stay NA, or go turbo/supercharger route!

It's not hard to port and polish a head but you can only port it so much and the design of the head and intake and exhaust is what is so much greater then toyota/yamaha's heads. The K20 is a great motor, simple bolt on's add crazy power plus the fact you can swap parts from other K series motor's like a K24 bottom and TSX cams and make noticable power gains is great.

I would hope it's a great motor as most of the technology was taken from the NSX :D

http://www.mr2oc.com/showthread.php?t=258259

247rwhp and 175 ft/lbs. Full intake/exhaust upgrade and ecu.

Before this I believe he had a 1zz turbo, 2zz na, 2zz turbo and then the k20.

worthwhile points, and i'd like to thank 1ofthesedays for posting his real-life experiences with the engine, my problem is that if its still down to the intake and exhaust, those are things that are can be fabricated, especially if your running stand alone ECU as to make ITBs possible, they exhaust is something anybody with a welder and decent understanding of exhaust theory could make, or none the less copy the demonsions of great working exhaust systems on same size engines if you weren't the curious type

im not saying i don't like Honda engines, i just think that since our engines have the strength nessasary, that the extra finesse should be squeezed out of it, but thats comming from somebody who would rather know why a car makes 140hp a liter, then simply own the engine upgrades to make 140hp a liter

It's not my car but a board member's car. I wish it were mine, though, as I'm looking for one that's the same color.

There's a new Corolla down under that's being developed for rally and is supposedly using some sort of 3s-ge. Whether it's a new variation or not, I don't know but it might be an option.

ummmm just a little factoid for ya...the k20 series out performs the f20c & f22c

basic bolt ons get you 265whp on an n/a type-s...forget the engine code.

and i do love watching the fanboys squirm =D. toyota and honda is basicaly a match made in heavan superior engine technology "honda" with the drive train and suspension setups offered by toyota....mmmmm goodnes.

For every Honda engine out there there is a Toyota equivalent with similar specs that is easier to swap in. You can put anything you want in an MR2 - but the only reason to do a K20 would be for uniqueness, and for the challenge of being one of the first to pioneer said swap.
 
#23 ·
I don't know if we have an I4 equivalent to the K20. I wouldn't doubt it if the K20 is able to outflow the 3S-GE. They both have similar specs...square bore 86mmx86mm engines with 11:1 or 11.5(ITR?):1 CR.

Honda also has very good suspension setups on their cars. I believe the new Civic SI can pull 0.9g..not bad for a FWD.

From what I understand, the 2ZZ swap isn't the easiest thing in the world, has a smaller aftermarket, and a decent amount of problems. Still, the fanbois blow a load over the thought of it.

The K20 is an amazing motor, no two ways around that. After graduation, I'd like to swap a 250whp or so K24 into a MK I and have more fun than I know what to do with. I have a friend who is a good fabricator (Put a TRANSVERSE F20B into a Civic with the D series tranny I believe.) who will hopefully be able to help me with the swap.

Of course, this won't be for another two years, possible even a few months longer.

Anyone that suggests going the 4AGTE route, or 3S-GTE route should be shot, The immediate response of the K20 would be out of this world is a nice exhaust and ITBs.
