So are there any TRD Superchargers left?

Well the TRD system is really maxing once you start spinning it faster. The M90 was somewhat designed to go on the 3.8L Pontiac, Buicks and Olds with their L67 engine.

The third gen M90 at maximum rotor speed is rated to about 500cfm. You convert that to lbs/min and it is only ~34-35lbs/min, then subtract the 42hp to spin the SC at 12,000 rpms to make that volume and you will see less than 310 crank hp. or roughly 205hp at the wheels.

So in your opiinion that is the optimum SC choice?
 
I'm sure I read recently the M90 was also used on the 1UZ-FE, but I'm not sure of any dyno numbers.
 
Rick,

If I was starting from scratch with no limitations on fueling? I would look at something like the Eaton TVS1900. Would be capable of great power and is big enough not to have to spin it out of control and produce lots of heat.
 
Optimum on stock fueling and stock timing? Yeah I think it probably is, like I said any more and you are at risk in closed loop, any less and there is no way it would be worth the effort.

But I think there is a lot more untapped potential and the current forced induction is much better, but you have to address the computer and that is just something most people don't want to do and I don't blame them.

When people PM me, I tell them straight away if you don't like messing with things and having to tinker a bit, just bolt on the TRD SC.

So in your opiinion that is the optimum SC choice?
 
For 400hp, well just a little under would be a TVS 1740, for a little over TVS1900 and for a budget option go for a Gen 5 M112 off of a 2004 4.6L SVT Mustang. They made 390hp at 4.6L similar to our 4.5L 1FZ.


lets say 400hp range.
 
Nope sorry to disappoint, just an unemployed, 36 year old man, living groundhog's day in Moab UT. :flipoff2:


Her name is Ry Ana Scott and don't tell me a damn thing different if it ain't true.

At ~100k miles the blower needs an overhaul. That runs ~850 bucks plus pulling it off and putting it back on.
 
I had an update from Magnuson Supercharges this week. They still think that it is a good possibility that they may bring back the TRD supercharger. They however said that the process to do so has been taking longer than they expected. They offered no details on weather it would be them or Toyota offing the SC if it becomes a reality.
 
I am not in a position to take this on but you can get almost everything to bolt a system together with the exception of the intake (from the stock airbox MAF to the turbo inlet), the charge pipe (from the turbo outlet to the TB) and the downpipe (from the turbo to the stock exhaust) Any decent shop or exhaust shop could do that for you.

If I was building a BUDGET system to mimic the TRD SC that is; low boost, approx 60-90hp increase, no intercooler etc this is what I would do.

Remove stock manifold and y-pipe and bolt on the
Treadstone cast manifold with T4 flange and wastegate flange built in - $419
http://www.treadstoneperformance.co...name=Toyota+Land+Cruiser+1fzfe+Turbo+Manifold

Then bolt-on a
Borg Warner S200SX 770 Turbo, T4 single scroll, WITH V-Band flange. - $848
http://www.full-race.com/store/turbos/borgwarner-airwerks/borgwarner-s200sx-7670-turbo.html

Then bolt-on a
Tial 38mm Wastegate - $239 Get both the 6psi and 7.5psi spring
http://www.treadstoneperformance.com/product.phtml?p=453&cat_key=157&prodname=Tial+38mm+Wastegate

Have an intake tube made from the turbo to the stock air box, weld on the provided flange and bolt-on a
Tial Blow Off Valve - $259
http://www.treadstoneperformance.co...9&cat_key=3333&prodname=Tial+Q+Blow+Off+Valve

This is kind of tough but remove the lower oil pan and bolt-on the
Treadstone turbo oil supply and drain kit - $105
http://www.treadstoneperformance.com/product.phtml?p=67759&cat_key=614&prodname=Turbo+Universal+Oil+Supply+and+Drain+Kit,+Pro

Bolt-on a
Downpipe V-band flange and v-band to connect to back of turbo - $63
http://www.treadstoneperformance.com/product.phtml?p=69196&cat_key=662&prodname=Treadstone+S200SX/S300SX3+V-Band+Downpipe+Flange+V42350

Add the
Silicon Coupler to attach MAF to Intake tube - ~$8
Silicon Coupler to attach Intake tube to Turbo - ~$8
Silicon Coupler to attach Turbo outlet to charge pipe ~$8
Silicon Coupler to attach charge pipe to TB - ~$8

tighten the bolts on the
4 Worm drive clamps - $10 (2) for the MAF to Turbo inlet, (2) for the turbo outlet to TB
http://www.treadstoneperformance.com/product.phtml?p=67769&cat_key=612&prodname=Worm+drive+Clamps

So this is $1985 and mostly "Bolt-on" ;)

All you would have to do is bolt this on, and have someone fabricate the Intake pipe, the charge pipe and downpipe. And you are done. You can swap the Wastegate spring between 6 and 7.5psi of boost to see how everything lines up, the turbo is very undertaxed so intake temps will be fairly low. Again this is not my all out performance build, but this is all very high quality, there are no Chinese crap parts like in the CXRacing kit. This is going to put you almost identical with the TRD SC'r but it will also have some of the same issues those guys can see on really hot 100+ summer days with high intake temps, because neither setup has any kind of Intercooler but the TRD guys have been handling this with meth injection, after the fact intercoolers or higher octane fuels.

This is interesting...

Would a set up like this be supportable by the stock ECM or would a person need to change the mapping?

Also, my LX450 has ~170K on the clock, would changing the head gasket be enough to support such a mod or should this be done on a freshly rebuilt motor?

Thanks!
 
Yes that was the object when I wrote that post.

My bottom end has 165k miles on it and I am making 2.3x more power than stock, without issues.

Thanks, your the man! One additional question... When I am changing out the HG, should I do any port/polish/3-angle valve job or is that all stuff that is best w/o forced induction?
 
No that is all great stuff with forced induction, you will just make the same power but at less boost pressures.

There is quite a bit of room to make the 1FZFE breath easier. So really the sky is the limit.
