Style Posted April 30, 2020 Share Posted April 30, 2020 I think they offer more torque down low but due to the increase in rotational mass, a lot more work (mainly in the head I'd imagine) is required if you want to rev it's tits off. I don't think they really offer anything up top but if you couple it with VVTi and a tricked out head, it would make for a nice power graph. It depends on what you're after really. For the price of them and the capability of tech we have nowadays with the standard 3.0's, I'd say it's a luxury most can do without. The billet block guys and serious drag racers all keep to the 3.0 and 3.1 range with the preference of higher rpm. But that is what suits them as they only need to get into the power band once (leaving the line) and can stay in it for the rest of the pass. Shawn Preece on here has a 3.4 if you wanted to check his build thread. Makes over 1000hp and has dyno graphs up as well to give you an idea Quote Link to comment Share on other sites More sharing options...
Noz Posted April 30, 2020 Share Posted April 30, 2020 I've looked into this before. The only reason I can see to doing it, is because you can afford it and want too. With E85, pre-spool nitrous and torqamp electronic turbo technology making low end torque available (honestly, check Supra Torqamp on youtube), there are other ways to gain the benefits that come with a stroker. I'm looking into a switchable E85 system also (pre-spool E85) - I'll certain I can make it work. But. That said. They do seem to sound different. And let's face it, it's friggin awesome. You could have a stroker and gain more power easily. Saving investment into the head. I have yet to see however anyone recently who has a 3.4 use it for anything low end. I've been analysing people's skewness on their dyno's for a while. To improve my own. 1000hp is a strange target, without consider when and how. Imagine is we talked about a power value and skewness of the curve. Quote Link to comment Share on other sites More sharing options...

Mo Reviews Posted April 30, 2020 Author Share Posted April 30, 2020 Thanks for the information chaps. From my understanding, a stroker kit isn't really required for anything up to a 6870 size turbo. Also, considering I have a high stall TC and VVTi, I won't really benefit much from the low down gains... Quote Link to comment Share on other sites More sharing options...
Sheefa Posted April 30, 2020 Share Posted April 30, 2020 PM Shawn Preece and he’ll give you the lowdown on these having had one installed. They can get very expensive with supporting mods too if going big power... Quote Link to comment Share on other sites More sharing options...

ShawnPreece Posted April 30, 2020 Share Posted April 30, 2020 Pretty much agree with everything that’s already been said, it’s just 1 of a few methods of improving spool with low down torque and the more of these methods you do the better your spool will be. There are cheaper methods of gaining the same if not more on spool but as mentioned above your not only getting an increase in torque to help with spool it does alter the sound too it’s much deeper and everyone has a preference but to me I love it. I’m just starting to build my black Supra now too and I’ve got a vvti engine to go in but my goal is very different with that one I only want about 700bhp from it and my goal is the ultra fastest spooling 700bhp that I can do so starting with the vvti engine and most probably a precision 6062 gen ll turbo (or maybe Garrett equivalent if the spool is comparable enough) I will see how that drives and then my plan will be to take the engine back out to 3.4 the bottom end aswell so with the vvti head the fast spooling turbo and the 3.4 bottom end I think that will be a really good street setup with very little spool time. Basically explaining this as it shows how much I do love the stroker as I will go stroker on this one too. A lot of people will say there are cheaper methods of improving spool and I 100% agree with them but it does work and in my oppinion it sounds amazing so o am a massive fan of stroker Quote Link to comment Share on other sites More sharing options...

Out of curiosity, in terms of cost, primarily because Noz mentioned it earlier; on average, how much does a stroker kit add to a normal forged engine build? As for your street 700hp build, I think you'll need to go with a 6262 at a minimum to hit your desired output. I'm running around 700hp at the moment and my 6262 is holding the power strong to the redline without any pull back or loss in power. I'm also on full boot at around 3.5k with no head work whatsoever. Edited April 30, 2020 by Mo Reviews (see edit history) Quote Link to comment Share on other sites More sharing options...

Hmm hard to say exactly bud as there are so many options of components that go into it... it’s basically machining costs on top of what the kits cost... The 6062 is a gen ll turbo bud so a different range to the 6266’s and so on, they claim 750bhp off it so thinking it should do 700 ok but it’s mainly the technology in the gen ll for the faster spool I’m wanting Quote Link to comment Share on other sites More sharing options...

Frank Bullitt Posted April 30, 2020 Share Posted April 30, 2020 Is this the one? Yes, they make them to suit everything from a 3.0, 3.2 and 3.4. They were around 4K for the crank when I last looked into the stroker kits a couple of years ago. An off the shelf kit is okay but it’s much better to put your own together. Not a cheap option but if you are serious about torque and want to do things properly it’s the way to go. Especially with VVT-i. Your limiting factor is going to be the Titan box Mark fitted.

I'll definitely have a look into it, thanks! That Titan box was more or less ruined by the time I got back from JM Imports, trust me, it didn't need a stroker kit for the KO! As it transpired, a genius, for reasons unbeknownst to me, decided to use longer than the factory bolts to secure the sump and (must have) used an impact wrench to screw the bolt all the way in to the geaebox housing, cracking it in the process. The same genius (must have) realised his mistake and attempted to conceal it by, literally, cementing the sump on to the gearbox housing. This obviously didn't survive the journey back as the car was sitting in a pool of transmission fluid the following morning. It goes without saying, the box was then completely overhauled with a new donor housing and some tasty Stage 4 upgrades as most, if not all, the clutches were completely burnt - images below: Quote Link to comment Share on other sites More sharing options...
Noz Posted May 1, 2020 Share Posted May 1, 2020 If you dont buy a stroker kit. Definitely buy a torch for night time photoshoots lol I always wanted the Titan 3.5 stroker. For no other reason than to aid a 1/4 et. Power is easy. Power on the left of the curve seems to be ignored these days. Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted May 1, 2020 Share Posted May 1, 2020 Power is easy. Power on the left of the curve seems to be ignored these days. That’s because everyone is so concerned with chasing HP at the expense of torque.

They much prefer the ego massaging, overinflated rolling road figures I like torque, hence my interest in a 'stroker kit'... only concern with an auto and a high stall (3800) is how it will deliver that power to the road without lighting up the rear wheels and/or breaking something?

No good having power then being destroyed by a standard R35 which cost less money. I didn't take those photos!

Noz Posted May 1, 2020 Share Posted May 1, 2020 Why not look into an E85 switchable system? Be cheaper than a stroker kit. Though no one has ever designed such a thing. But I want to! Or nitrous.

I may decide to use nitrous to aid spool but I wouldn't want to use it as a standalone system without some form of mechanical upgrade, in the form of a stroker kit, or otherwise. I already have an E85 capable fuel system, what do you mean by switchable? Quote Link to comment Share on other sites More sharing options...
bignum Posted May 1, 2020 Share Posted May 1, 2020 If money is not an issue go for the stroker, they`re not as reliable as you would think, so a year down the line when/if something fails and you have to fork out for another crank...... you can`t just fit a NA 1.

I already have an E85 capable fuel system, what do you mean by switchable? Everyone uses E85 in the tank. Which is in my opinion, only suitable for a track. In my opinion, E85 should be used on a button when you want it. You don't have nitrous being used between bursts it's the same for E85. Why is this the case? It's the case because people map in a fuel sensor and blend in the tank. If you could visualise the actual boosted E85 vs the distance travelled using E85 off power it would be obvious to most. I plan to have a separate tank, second fuel line, and potentially second set of injectors to feed the E85 mix. Ideally, you'd have it blended in the fuel line, but I'm not sure how I could switch fuels quick enough without using the injectors. Why has no one tried this? I've no idea. I don't think any other way would work quick enough, as fuel pump operation (on/off switching) isn't quick enough. Whereas two separate fuels recirculating constantly, the other when not in use would work (E85 system off when map not running). This is obviously a theory, you would either be racing or not racing so no one with any money has ever thought to trial a system or desired it. But for me, I don't want to be pulling over dumping in E85. Nor hitting traffic with a tank full of it, only to have to mix some more. Pain in the a**. Bignum is right, reliability has been raised a few times with them too. The rods are designed for the cranks, so a built engine can use a stock crank. Stroker setup would mean forever needing the crank. - - - Updated - - - So reliability is questionable? What's a NA 1? A non turbo crank is what he means.
