It's must be sweet to live near Robbie.

Also curious about Robbie's impression of this gasket. Aside from the ability to adjust compression, does he think it would it be a good gasket for a stock motor? The oem head gasket for the 2JZ-GE and 2JZ-GTE inline 6 motors are MLS and widely accepted as bulletproof. The 3FE and 1FZ must have been designed before this type of gasket was approved for use internally at Toyota. I've searched for a MLS gasket for the 1FZ before, but come up empty. I know the new oem gasket is vastly improved and now seems to be a closed issue, but a MLS gasket could be another great option. MLS is now the industry-standard solution for cast iron blocks with aluminum heads.

BTW, the rebuild looks great! Good luck with it.

The Cometic HG part # is C-4530 and then you just change/add the last three digits to meet your bore increase.

Again, thanks guys.

the stock Fuel pump has proved to be more than adequate for the job at hand. I'm sure it's not going to be a problem but then again I don't see it as an advantage either.

The autometer wideband will not read below 10.0 AFR i think while the innovate will read as low as 8.0. This has help on the 95+ trucks as they tend to have an AFR greater than 10.0 at WOT stock.

I had a BEGI RR FPR but gave it to a fellow SC'd 93 truck. It will be nice to see how well it does for those trucks. The downfall of these is that it responds to pressure and the actual density of the air can change while the pressure doesn't which lends to fluctuating AFR readings.

Beowulf -

The 1JZ and 2JZ motors from the Supra turbos come stock with a MHG. The earlier Supra the 7MGTE did not and suffered many BHGs with boost levels above the stock 6ish levels. All 7M owners going for big numbers install the MHG. You can see plenty about this on the site: 7M-GTE Technical Discussion - SupraMania ...this is a direct link to the 7MGTE section.

That's what I told a buddy of mine that fabs for Rod Hall. He asked if it was going to be fast? I said probably "Acceptable," but not fast. We will see.

When I compare mine (bored .040 and SC'd) to mountjoy_99's (just SC'd), it's got noticeably more nut, and I have a boatload more weight.

Congrats 24, I'm excited to see this thing get finished!!!

Thanks me too.

Thanks Sean. Plenty to read there. Hopefully they will let me use the search without joining as a member.

Nice build .. how much you gonna bost it .? 7 maybe 8 PSI . ?

Stock rods .?

Here's an injector and info sheet back from WitchHunter Per.

If there is a four wheel dyno around I'd be game (I know there is not one in Reno). I'm not expecting the numbers to be all that impressive. It wasn't that much of an increase in displacement and I don't think we are going to increase the boost right off the back.

My goal was to build this engine to be strong and perform well with the s/c. I wouldn't mind going all out an another one in the future. Kind of like a multi year build up on the totally wild side.

I have promised to leave the boost alone for awhile...so we will have to see. I did use the stock rods as they are very beefy and balanced nicely. Much like the crank in this thing.

I did get a quote on those billet rods from UAE and while they are very beautiful, I passed at a little over a thousand bucks for six rods. Maybe in the next one HAHA!

Thanks again for the compliments.

[beno]

Your build here is quite impressive.

I assume you outsourced the machine work and the like? How much did all of that run? (not talking about what you are paying Robbie)

I have a shot 1FZ sitting around in my living room (seriously) and I am tempted to make it a long term project (couple of years) and would like to get a parts list with part #'s from you if I can.

Nice job.

Beowulf,
Couldn't reply earlier, but now I've got a chance to provide a couple links:
Head gasket - Wikipedia, the free encyclopedia
Head Gaskets
Why Head Gaskets Fail - Read about the Toyota 3.4L
Head Gasket Failure, Larry Carley, Underhood Service, August 2002
Federal-Mogul - Fel-Pro PermaTorqueMLS Head Gaskets

The main concern with the MLS gasket is the surface finish required on the head and block.


As far as my statement about the 2JZ engine, I've owned a vehicle with the 2JZ-GTE motor for over 8 years and frequent boards discussing that vehicle. It is common knowledge to members of those forums that the 2JZ-GTE with stock internals and head gasket can easily be pushed to 800 hp at the wheels. Boost pressures of over 30 psi on the stock head gasket are not a problem. I can't find info tonight that I consider credible enough to post a link to. Most of these high hp guys aren't making a big deal out of the fact that they use a stock head gasket (they list out the many aftermarket parts, but not the stock parts), so you have to look for the ones that specified they have never opened the motor to be absolutely sure. Many others brag of stock bottom end, but don't mention what head gasket they're running. The connecting rod bolts are the weakest link in the 2JZ. They "only" take about 1000 hp. Less if you raise the stock rev limit.

Beowulf - Feel free to take this to PM for more discussion. I'll be weighing this HG material decision too for future maintenance.

Fuel pump flow rates - Ask and you shall receive.
Stealth 316 - Fuel Pump Upgrade Guide

This article is excellent. Take note that a stock Supra runs fuel pump at 9v until under boost & WOT, then the fuel pump ECU kicks the voltage up to a regulated 12v. This keeps noise and heat low when cruising. Many people running more boost or larger turbos will bypass this fuel pump ecu circuit and run heavier gauge wire to get a little higher voltage at the fuel pump. Many also run dual Supra pumps, or dual Walboros. The Supra Denso pump is very voltage sensitive related to it's flow rates. It also pulls a 'lot' of current. Make sure the wiring is up to the task.

No problem O, I'll p.m. you. I've posted the part numbers that I have used for everything except the pistons. Honestly, I don't think I would use JE Pistons again. They were over three weeks past due when they finally arrived. It took quite a few phone calls (Daily in the end) from the machine shop and myself to finally get them here. We had to talk to the supervisor to finally get them. This is from a company that offers overnight service of custom pistons.

The service I received from JE left a lot to be desired. At least with the rep we dealt with. According to my machinist, he has had stellar dealings with JE until the last three custom orders dealing with the same rep.

Thanks Bruneti, this will give me plenty to read. I'm not anywhere close enough in knowledge to ask questions.

The link to the Supra forum confirmed what you are saying about the finish needed on the block and head. I consider that a con though a very minor one.

Long term project? Hell, if it's already in your living room turn it into a coffee table in the meantime. C'mon, a nice piece of glass over the top and your done.

No need for glass it already has six cup holders!

[24HOURSOFNEVADA]

The motor is installed, tuned and running. We (Robbie and I) took it for a nice run this morning. The motor is strong and pulls nicely. I'm putting miles on it to get it broken in and then the fun will really begin.

As for Robbie, aka powderpig, he's off on to his next "Adventure." I cannot express my thanks enough for his help and expertise. He's a true professional and that seems to be hard to find these days.

Awesome! Robbie really is an amazing mechanic and an amazing person. I like the look of the color scheme chosen and the block looks better now too! Excellent excellent excellent!
