Toda 2150 or Brian Crower 2350 stroker kit: Which is better?

[terry]

Hello, im terry and im a new to this club.

From the forums, i can see that most members were pretty helpful in feedback, and hopefully this could lead me to a correct decision!

Right now im planning to install a stroker kit, as it is the best way to remain N/a and driveability yet gains power ( race cams hurts driveability a lot although raise lotsa hp)

However, there are 2 good options now: to go 2.15 or 2.35 , price is almost identical. Can someone please tell me which is the better option?

Welcome to the site. Without wanting to put you off or send you away, you might find some relevant information already posted on this site:

www.k20a.org/forum

I've just tried a quick search on there and found quite a few relevant threads, so this should help you form an opinion on which is best for you.

I'm genuinely not meaning to be unfriendly, just that I'm only aware of one Toda stroker installation (TDI North aka Toda Europe) and no Crower ones, so there's probably not much experience of comparing the products to draw from here.

Hope that helps?

forgive my stupidity i would have thought that a stroker kit and fitting it is gonna cost a lot of money(Toda one is almost £3k + Vat and then fitting. Would it not be cheaper to buy just to buy a K24 motor?

What would the benifits of a stroked K20 be over a K24?

You would probably neutralise the costs buying the K24 and selling your K20. Apart from other things, i'm thinking the header will be different because of the block height? and i'm not sure about the ecu, or if it would just need to be mapped?

:?:

Hmm, logically, it seemed that a bigger cc could give a better hp, as that happens to most situations example Ferraris, Lambo models, even the flagship NSX, i had seen a rsx put a Crower kit and cams: he got a 280+ hp of it !

That being said, im still a craze enthusiast of Toda. I've got Toda's A2 cams( provide add. power but no effect on driveability at all), Hondata, Ex. Mani, Exhaust, Clutch+Lightened FlyWheel, basically just missing out the big boys like ITB or a stoker kit.

About the K24, can you tell me more bout it as well? Im not sure if i would want to get a 2nd hand block, cos im afraid of power loss and shit since the engine does not go as good as newly forged stuff.

The disadvantage of the K24 is that it's a long stroke engine and in standard form you can't rev it anywhere near as high as the K20. So even if you fit a K20a top end, if you still want revs you'll be needing to think about rebuilding it with stronger bottom end components anyway.

Can I suggest you follow the link I posted above as all of this information is available in a lot of detail on that site... :idea:

For K20 blocks, TODA stroker kit stroke is 90.7mm (modified 2.2 litre S2000 crank) and Brian Croker stroker kit stroke is 92mm (custom billet crank).

If you're talking about ~2150cc's out of TODA stroker kit I take it you'll be just honing the OEM block and using 87mm pistons (87mm bore & 90.7mm stroke gives 2157cc). Considering the same size pistons, Brian Crower stroker kit gives you 2188cc's (87mm bore & 92mm stroke).

2.35 liters that you're referring to is 2340cc calculated with 90mm bore which is not good for street use and requires block sleeving. Considering maximum street-usable bore of 89mm for K20 block (sleeving still required) the maximum displacement from Brian Crower stroker kit is 2289cc.

I see. In other words, you re trying to say that Toda is still the overall best choice?

Does upsizing your engine makes fuel comp. poor?

 

[timp]

your gonna spend all this cash on your engine and worry about poor mpg?

Put it in the garage and get a bike :lol:

 

[rarerims]

Stroker kits on a natuarally aspirated car, in my own experience, give you bucket loads of torque, but not nesercerily more power...

You cant rev them like you can a short stroke..

I wouldnt do it again.. :!:

I see. In other words, you re trying to say that Toda is still the overall best choice?

No, I didn't put them into any order but just gave some thoughts on the displacements and things related to that. I can't say which one is better due to not having experience on both. I personally went with the BC stroker kit with Darton 89mm sleeved K20 block. That was mainly because I wanted/needed to sleeve my block to larger bore anyway...

To be honest mate this is something I'd talk to my tuner about, or check on the US K20 forum as Evs suggests. Stroker kits in the UK for the K20 are few and far between, though currently TDI has two cars, one with the Toda and one with the Crower kit, well that's the way I see it from their website. You could try calling Paul there and ask his advice?

One things for sure though, it's a lot of work and a lot of money, so make sure you know what you're stepping in to before you go ahead with the work.

i think you probably need to think about what you want and where you want to go before making a decision.

In the long run do you plan to stay n/a or are you thinking of boost at some point?

No ones ever gonna be 100% happy but what kind of figures do you think you are looking for?

How deep are your pockets?

 

[terry]

Basically, i want to improve on the car's performance by not sacrificing comfort ( as the car is really on the borderline of comfort), not too much fuel ( ITB drinks fuel like water)

I ve seen people gain from 30-50 hp by putting the stroker kits, so it should be good. Most probably i ll go with Toda anyway cos most of my stuff is Toda.

BTw, anyone here uses Toda Spec C cams? Does it makes the ride uncomfortable?

 

[jostrom]

TODA Spec C camshafts are "VTC killer" camshafts, so they require you to disable VTC by using a "normal" adjustable cam pulley with the intake cam. They do make your torque curve uncomfortable for a road car.

There are better cams in the market than those.

Guys, anyone had any idea how to put photos of your car into gallery? cos it doesnt allow me to do so... it says need authority and i doesnt have it
