Bolt on turbo kit (5 Viewers)

[Bludozer]

I bought my turbo 80 before it hit 2nd and that was before I knew the price

I have a boost gauge but when its moving to the plus side I need to watch the road

Not sure how much experience you have with SC 80's, but are you able to comment (or guess really) on long term reliability of turbo vs. SC? From someone with 0 experience with both, the 1FZ doesn't really appear to care too much about either but reliability would be more of my concern than total power output. Leaning towards the purchase of this kit at the moment, especially since every single component posted so far has been completely over-engineered to the specifications of our OCD overlord.

The failure tempurature usually follows as some number close to double the "cross linking" temperature with a few exceptions. Polyester powders will burn at a pretty low temperature (under 500°). Silicone powder coating stretches it nicely, curing just under 400° and holding up to 1200°.

Some ceramics cure at °550 and hang to that 1200°+ range, others (like turbo black), need over 750° to cure but hold up close to 2000°.

All have their ups and downs. High temperature resistance, flexibility, UV stability, corrosion resistance, impact resistance, ease of application, smoothness and gloss are all traded around depending on the coating and no coating does it all, unfortunately.

This is all good info for some of us considering coating the exhaust goodies to reduce underhood temps. For some reason, my P O installed an EGT sensor in the #1 exhaust runner about 2” from the head. After reading temperature discussions from turbo/diesel owners, it’s a little scary. I will assume that the high dollar gauge is somewhat accurate. It is often reading in the 1400-1500 range when I really get into the boost. Doesn’t sound like many coatings will survive that?

Well 2 things to remember, well actually 3.

1st. You are not coating the inside of the runners usually.
2nd. The temp inside the runner is not what the outside of the runner sees. The exhaust travels fairly quickly and cools rapidly.
3rd. Gas EGT's and diesel EGT's are very different. On a boosted gasoline engine as long as it is below a prolonged 1650-1700f it is fairly safe.

So you could put one of the coatings on the manifold to help with underhood temps. But make sure you do your homework and pick a coating like the Swaintech or the one Dogfishlake found that has a thick enough coating and high enough ceramic content to actually work and not just be for looks.

Yep SC'd for several years with all the fixins...never again even if its free. Flame on my choice

I cannot answer in term of comparison of longevity but the Turbo in my 1997 was installed day one and had its first rebuild with the turbo replaced 2 years ago at 158K now with 160k the turbo is water/oil cooled (◄preferred for longevity) In term of performance SC are for guys that have never driven a Turbo 80

Why was your experience so negative? I understand that a turbo may feel better for various reasons but nearly all SC reports I see are quite positive. Was it related to reliability or just not the performance you wanted?

Also, purely out of curiosity...any idea what the Safari Turbo set-up cost as an option in 1997? I'm guessing it was ridiculously expensive for the time.

A roast beef sandwich isn't negative, but it isn't a steak.

ill take it if you don't want it. ill drive from Yuma to phoenix to get it too...

Enough said.

He probably wants to give it to me, its only a short jaunt down the street

Then my SC 3RZ Tacoma won't feel so lonely

I'm already unbolting it... shhh don't say anything to phil. he doesn't know he gave it to me yet...

DId not like the drivability and the way the power was delivered and heat is a huge problem in AZ.

The Safari Turbo is a complete kit that addresses everything needed for a solid reliable set up including new trans cooler huge intercooler all for around $8500 Also CARB certified in CA.

Word on the power delivery/heat. My Tacoma was pissed about this place and boost before I put meth injection on it. The power comes on so fast these old lazy Toyota ECUs have zero chance to adjust in more fuel, so knock happens and then they retard timing a buttload. Meth made it high boostable here again though, cools the air charge a lot. My dream is to leave AZ soon though so hopefully I won't need it anymore back in WA.

I wheel regularly with a very well built dealer maintained SC 80 with meth injection and ever SC mod available including a switchable SC and I have see his hood up many times.


Done with the SC talk this thread is about 80 Turbo charging and in the end that is what you WANT!

Way to open a Phil. Long term I think a quality turbo will far outlast a supercharger. With so many contact and wear parts superchargers loose boost over time as seals wear and cause the engine to fall out of tune unnoticed.

Sounds like he should probably find a better tuner then, wouldn't expect a dealer to have much experience with meth injection or anything aftermarket. I find more often than not they can't even be trusted to figure out stock things anymore on vehicles this old. My Tacoma has been rock solid, even with the heat here. The 80 I leave mostly stock, but boost is always fun so I've considered turbo and SC for it.

 

[scottryana]

What's a tuner going to do on a vehicle that can't be tuned?

Meth injection isn't going to help with the heat soak of the SC or blocking the airflow through the rad. Meth injection is only for intake air temp, not coolant temp. People often confuse the two.

For me needed service after 20 years and 150K+ is respectable for something that make you ride haul ass

Didn't realize he meant the whole thing was overheating, really shouldn't boost anything that is already prone to overheating. That's a separate issue to sort out.

I've got a piggyback for fuel and spark on the Tacoma and of course the meth kit has some adjustments of its own. But keeping the SC cool and enriching the mix up a bit should still help temps. I should mention I spray before the rotors. I have no IC on the Tacoma so it was my only option and the richer mix is a nice bonus for part throttle boost which is commonly the biggest issue folk seem to have. I can bypass the piggyback and the meth kit still keeps it running pretty dang nicely if I don't purposely act like a goon and push its buttons. I also have no issues with coolant temps, never seen it go over 194 actually.

Well I'm interested in seeing how this kit progresses either way, been a while since I've had anything with a turbo so it would be fun again. I kinda like sorting out tuning (the stock Yota nonsense isn't tunable but there are plenty of ways around that).

Thought your manifold cracked way before 150k?
