Possible TX Stroker build.

[LINUS]

I hate to be a Debby downer but I think your best bet is to layout your goals and your budget and get feedback that’s appropriate.

Most common sense reply to this situation.

That’s why I’m here! I can spend about 25k on the Motor before I start regretting it. Throw your ideas at me please. I want a performance 1fz but not to the point that it has to be rebuilt like a race motor or break leaving me stranded in the desert.

So, have you made ::any:: -contact with Robbie?

I’m a strong proponent of a 4.6 & give Robbie the $1K to hand P&P the head.

ARP studs in prep for going forced while being done.

Drive it for a short period. See what you think.

If that’s not enough, go for one of Joey’s turbos.

A full 4.6, P&P, turbo installed by a shop will prob just break into the $10K+ range, but leave you with a stock ECU you don’t need to have any shop repairs done by a specialized shop familiar with stand-alone ECU’s etc.

But that’s me- by what you stated it sounds like that would be enough motor for your use.

But if you have a chub for going stroker of some personal reason, ready, fire, aim. Go for it.

However, realize I typed ready, fire, aim - in that order intentionally.

I’ll be interested on your impressions of a stroker kit in the ‘hindsight 20/20’ POV, if you go that route.

Anyone got a price on an engine or head from Robbie or a link to the shop? Our local shop closed and I might need another head done soon if not two.

I see things like this on Instagram from other countries and wish I could find the builder. But it’s all foreign and photos are all 3rd party with no tags to the owners.

 

[jacksna1982]

And this engine was done well.

 

[jacksna1982]

Not that I would want a destroked motor like this to rev and race but that build would come with a lot of useful info to apply to our rigs as well.

 

[slow95z]

Man you are really pushing this aren't you... Call up a Supra shop and ask them about stand alone ecus. They can get your bank account info and role with it. It's only money right???

 

[jacksna1982]

Man i guess you guys are happy with the info here and how far you have progressed with your engines. Will do my thing and keep it to myself i guess. Thanks to the posters who contributed information

 

[NLXTACY]

No the problem is over the past decade we’ve all heard this same conversation dozens of times and it’s always ended the same way. There are the trailblazers but that’s the exception.

Not satisfied, I am trying to give you the real deal on the 1FZ engine. Buying a Brian Crower stroker kit is throwing away your money.

I have told you if you want to stroke the engine, you need to have a custom piston made with less compression height, a smaller pin and a custom longer rod. To do that you would need a custom crank as well. Those 4 parts (pistons, pins, rods and crank) alone are probably going to be ~$10-13k.

Then you would need someone who is familiar with the 1FZ to do a couple of things ( 1. order a GenII 1FZ head from overseas and modify it for a cam sensor, 2. use your stock head but deal with the poor cam signal from the distributor)

Then you will need someone to pull the engine, go through everything, do the machine work, reseal the engine and put it all together, get the proper size injectors, upgraded the fuel pump, and wire in a stand alone ECU in parallel to the stock ECU. Then they would need to get it on the dyno and spend significant time developing timing and fuel tables.

You could do it for $25k, if you did your own research but not if you have to pay someone to learn while they do it.

Your $25K isn’t going to get you a motor like you see on the ‘Gram.

Between niche shop builds from guys who do those all day long for shop promotion rigs to literally -Sheik sized bank accounts- there’s guys doing stuff all over the world.

For example - look closer at that last 1FZ - It’s coilpacked because it’s a distributorless version we didn’t get.


We could go further talking billet CNC’d Supra blocks, stand alone management, etc - but it’s only a viable thing to do if you understand every inch of what’s going into your rig, because **if** you break it somewhere in the boonies - you’re the only on-hand tech.

I’m not trying to be saltly at you - but like @NLXTACY stated - you see many guys talk a talk, but when rubber hits rocks, roads or whatever, a full-blown Supra conversion motor or any of that isn’t realistic.

How about balancing all that $25K into a good refreshed & turbo’d motor & some great suspension, some extras for how you want to use the 80, and have ~$5K or alot more for gas, more goodies down the line.

Nobody fears change here - and really the guys who prove it best have a 2FZ conversion if you want a $25K way to clear that account balance. It’s a ‘Yota V8.

:::2UZ conversion:::
I’m trying to keep too many motors in headspace.

It’s $20-25K turnkey, and the quality swap shops keep it so clean they don’t look at all like a swap.

So just a thought. Is there a reason not to just simply try the Wits End turbo as is? See what you think and maybe have a better idea of where you want to go? If you really want to do a custom engine build then self installing the Wits End kit should be relatively easy. It is pretty much plug and play. The added bonus is that if/when you break something as you experiment with adding boost, just look at doing the engine rebuild that you are already looking at doing... You can look into Robbie or a stroker build. The bonus with this path is that you might meet your power goals without needing something exotic that could be really hard to fix or get dialed in. It seems like a win win.

To me the OP wants a show engine but doesn't know anything about what he wants
Does not understand the concept of stand alone ECU tuning, does not know the stock ECU limitations but wants lots of hp that can be easily generated from a pretty much stock engine with a stand alone and Witts End turbo install!
Ultimately his limit of $25,000 is not enough, based on his knowledge, and his desire to have an engine that looks like the Instagram pics he posted.

A lot of his questions could have been answered if he searched this forum......

This thread will die, along with his dream......

 

[BILT4ME]

I hope this thread does NOT die. While I don't have anywhere near the cash to support this thought process, I have been surprised there have not been more attempts with this.

@scottryana has committed serious amounts of time and his money to come up with more HP and making some interesting advances we are all talking about.

He has different goals and plans than the OP appears to have.

The OP is thinking way outside the box and he (and all of us) know that folks in the Middle East have done some huge HP changes to these. They have more resources than in the USA, but it doesn't mean it cannot be achieved.

I believe the OP can achieve this but I also think the $25k is way low by the time it all gets figured out.

There will need to be parts brought over from ME, finding someone that's has done builds either there or here on Supras in order to find a shop willing to jump on this. Realize it will all be on your own dime and I think we are talking Joe Rogan dollars by the time you achieve this goal.

Others have attempted, but ran out of dollars, time, and desire to achieve the goal.

Good luck to the OP. Please post your findings to help others achieve or use your info as a stepping stone.

That's what @scottryana has done with the Wit's End turbo.

Good luck!

This is why you are stuck in the past. You think you own this place and are the end all be all. I think you should contribute and stop trolling. So if you have nothing to contribute get off my thread.

Greatly appreciate that post and will do.

I wouldn't let some negative posts make you give up on this thread. But you have to be careful to spend your money in a way that gives you the most hp per dollar. I think your goals are reachable for around 25k and that you will get the most hp per dollar on stockish bore and stroke. I think the only weak link on a 1fz if I recall is the pistons. So maybe go to forged pistons, head studs, and then rely on boost for your power with standalone efi and you should be able to have yourself a pretty powerful 80. Stroking the motor, port n polishing the head, camshafts, etc. do give some extra power. But I think the 4.5 stroke will be better long term if that's what your after.

LOL, stuck in the past? WTF, if only you knew!

Look, you came here asking questions, they pretty much have been answered if you searched. You were told by someone very experienced in the area, scottryana, the logical route yet you seem to refuse to accept the info.

And the last I looked you are on an open forum, so anybody can say what they want, whether you like it or not!

I am not trolling, You asked opinions and I contributed my opinion, and I do have knowledge in the field, and you don't like that opinion, so ....good luck, I will let you dream.....

If you do it by all means post your results, it will be interesting and maybe educational to all of us.

Sorry if I upset you, seriously. Best of luck in your dream.

Thanks to Fjbj40 I’m out with the build, cave here for help and he’s just Dick that is jealous for some reason I guess. Not sure what’s up his ass. Doing it off line and whatever results I get, well you guys will never know. Thanks for those who did help. Good luck to all

 

[IoN6]

Would it be better to go with the high compression bored motor from Robbie in Boulder? He has done many of them. Someone in Rising Sun in Denver has one. He was saying the HP/TQ is about the same as a supercharged 1FZ.

Also, why not one of them fancy new Turbos from that Wits End guy? If you wheel at elevation, a turbo is very very nice to have.

I heard this statement as well. But without dyno numbers or any other kind of proof it is just water / beer cooler conjecture.

Far from jealous, if I had $25k I know I would not blow it like you will! A Wits End turbo would get installed on the FACTORY engine, I would have plenty of power for a SUV, and factory reliability. You stated you want to travel off-road and xplore, well good luck with that high strung stroker one of a kind that you had someone build for you and you break down out there!

I certainly would not be measuring my dick like you want to with your stroker, no pun intended!

So, one person speaks and your offended and you quit that easily? Wow, great confidence!

Once again, best of luck!
