Nitrous will solve that problem...annoyingrob said:Except maybe the GT40-82
ive seen mustangs "fry" rings- overheat and burn the rings to a crisp. i thought about a bad head gasket but the compression check was all over the place- not in consecutive cylinders. im also thinking its a cracked head which also sucks because i have about 1500 bucks invested in the head, but its better than investing in pistons/rings i guess. assuming i decide to fix it.Doward said:Wait wait... you spent a year rebuilding your engine, and you DIDN'T replace every single hose you touched?
I thought that was SOP when rebuilding...
Further, if the hose just popped off, you should have immediately shut the car off (I'm assuming you did) - I have *never* in my life seen piston rings 'fry' (and just who the hell calls it 'frying the rings' - I've broken rings, swollen rings, improperly set the rings, hammered the rings, introduced enough cylinder pressure to accelerate the wear on the rings, but never 'fried' the rings) - odds are, if all the coolant suddenly evacuated, your warped the head/blew the gasket to hell.
Pull the head, and check, before making a decision.
Just my .02
Not trying to start a war or argue with anybody specifically but I think this is kind of misleading by saying that Precision "makes" the GT .... or that ITS "makes" whatever turbo they have; it gives some people unfamiliar with the whole thing a false sense of who really manufactures their equipment. On the fact that its a PT67 compressor - precision doesnt make compressors. Its a Garrett compressor that they have branded as their own.
Most of the turbo companies in the US do that - not that its a bad thing. Some of the turbos have very effective matches/mis matches for the motor they are being mounted on. Custom housings also give each turbo manufacturer a claim to their unique product, but when it comes down to it most turbos have garrett internals. They also have extensive race experience and customer feedback, something I wish that Garrett/Honeywell would spend a little more time on.
Personally, I prefer to stick with a turbine/compressor housing that was designed by the same company/engineers that designed the turbine wheel. Thats why I purchased the turbo I wanted for my application from a garrett distributor and didnt go crazy with an "anti-surge" delete or radical change custom housing.
Another thing I wanted to talk about is the whole T66 vs GT40 vs SPblahblahblah vs ITSblah vs PTblahGT vs blah blah blah. What really matters most is the efficiency of the WHEEL and TURBINE. Yes, housing is important, but if each wheel of equal size (GT series vs. T Series) is put in the appropriate size housing to maximize efficiency the GT will always win. Why? Just like a stock MKIV will kill a stock MKIII. Its a newer, more advanced and efficient design that was created to take the place of its predecessor.
It really cracks me up to see people comparing a T whatever to another turbo with a GT wheel and going on and on about how it is so much better because its an SP63 and its so much better than a GT40 or some other stupid shit. If price isnt the justification for preference of a T-series over a GT equipped turbo then they are WRONG. Yes, it might spool faster or flow more in the top end but it certainly wont do BOTH. Sorry - take it how you want but thats the way it is.

I have seen in person two MK4 Supras(in person) both dyno in the mid 600 range. One had a GT4067DBB and one had a BL67DBB(P-trim.68A/R). They nearly had identical spool and were running right around 28psi with similar mods. I was impressed by both turbos especially in the spool area, but it seemed that the BL(precision) did every thing the GT4067 did and can be had for less money. And I have no bias either way...

You probably could afford a 2jz. Get a 2jzge and T it. Check out my build thread and read some of the links. Its a lot cheaper than you think. Also look at hothenessey and see his build thread.
You could get one of those xs turbo kits for about 1k or so. Check out clubna-t.com user id 98mkiv They are usually pretty reliable but the only part that ive seen people talking about failing is the turbo on a few occasions. The mani and stuff havent had too many complaints.
Pretty sure the newer VVTI ones don't, at least I didn't see them when glancing at the gs300 service manual.

Many many people are making BIG reliable horsepower without them. Really they are there to help cool the piston and control detonation. But think about the stock intercooler size/efficiency too and other safeguards that are on an oem setup to eliminate the possibility of detonation....
I think that running a bigger intercooler, having a proper fuel mix and using a properly sized turbo at a reasonable pressure ratio is going to have a greater impact on detonation control than a set of oil squirters.
Yes, I do think they serve a purpose. But as said earlier, you can see a lot of people using big turbos and making monster power on the GE block. www.clubna-t.com
