1: the crank pully ( from what i have seen, those do not have any harmonic balancing? would def use the stock one.
2: why do you need a fenspot overdrive powersteering pully ? ( waste of money!? )
3: don`t use the nology plug wires! they SUCK! ( try to lett the car run in a completly dark room and you will see why.. )
4: would use stock crossmember bushings, you need a little flex somewhere to keep drivetrain in one piece
5: if possible: try to get a thicker "stock" copper radiator.
6: don`t think that hks clutch will hold 700awhp..
7: get some poly bushings for rear sub frame. ( need some form of flex. )
8: would def use the 6466..
9: moroso oil pan.

I think this will be a NASTY car. and i am by no means trying to be a asshole here... just trying to contribute with what i have experienced tru the years of tuning..


Agree 88.9%

(#4) Wont running Poly engine Mounts negate the need to worry about solid cross-member mounts since flex will come from those?

I know my personal build is not complete yet and not at the same level (nor am I insane enough yet to build to that level), but I've worked on and around and in 800+ HP mr2s before and a lot of this stuff applies...

Here are some of my big pieces of advice:
-re-torque your head studs after 200 and 1000 miles, stock floppy engine mounts help to keep bolts from backing out, including head studs. Put thread locker on just about everything thats not inside the oil of your engine, and use a paint marker to verify all bolts are properly torqued and thread-locked.
-Buy some prevailing torque or locking exhaust studs. Stock bolts WILL back out on you guaranteed... especially on a custom exhaust manifold.
-Be prepared to crack your exhaust manifold most likely around the wastegate areas a few times... even the best and greatest stainless manifolds will probably crack a few times before you get all the stress points figured out.
-Get some locking bolts (Stage8 makes good ones) for your front CV joints... the extra vibration likes to back them out and then spray your underside with axle grease.

-Here is the biggie... Have you thought of using a higher flow 5S oil pump from the Solara instead of just shimming your pump? most people will tell you that overriding the stock pump values is not wise... Flow is more important than pressure is, if your pump in the past was not delivering enough oil to the bearings and caused bearing starvation, it was probably not a function of the pressure valve not being high enough, but rather the oil pump not being capable of flowing enough oil through it at max RPM and high temperatures. I dont feel like looking up the part numbers for this, but Id suggest going here:http://atsracing.com/Parts/Details/E-OILPUMP. This will solve your oil starvation issues, NOT shimming your pump...

How about you guys let him build his car how he wants to. It looks to me like he has things planned out pretty well and is fully capable of making his own decisions on parts. Considering that he has been working on a 3s motor in his own car since before 80% of the people on this board even had AllTracs, I'm pretty sure he knows what's going to work for him.

Good luck on your build RM. Sorry for cluttering up your build thread, i know its rude. My apologies.

I don't mind advise from others if they state their experience as to why something didn't work. Like sleeper and I have been chatting privately, and found out some interesting things he has gone through. If someone makes a suggestion from hear/say. Like the wrist pins. If you told me about you or showed me a thread where someone broke one. I would strongly look into it more because I don't want to ruin this motor. But from what I have seen, ATS just started using them kinda like a sales push cause Wisco made the pistons for them. I'm not saying ATS is bad. But they are a company. And I'm sure the pistons and pins are better. But do you really need it? Seems more like they are selling you that they have something different then others more then solving a true problem.

Like with my solid rear subframe mounts. I made two sets before anything was available. My buddy wrote a CAD program and made 8. Pat was the other buyer for his car back in like 2005ish. He has been running them since. No one is telling him to change them.

I also chatted with Pat about the Moroso oil pan. He help them design it on his car I guess. He told me the main thing it helps is extremely hard right turns. That is where oil starvation could happen. Not acceleration. The Moroso pan is an easy fix for the right turn problem.

And the pictures are of me shimming my ATS pump. Which after buying I believe is just a factory 5S pump. I didn't buy a 5S pump and compare but it has the hook up for the crank trigger and everything for a 98+ Camry.

http://www.toyotapartszone.com/oem/toyota~pump~assy~oil~15100-74030.html

I believe it's that. You guys want me to buy that from a Toyota dealership. Take photos next to my ATS one and then return it?

Water/ meth?

One of my old modified or super streets has an evo making like 60 extra hp at near stock levels( stock turbo that is). Ill have to check but to me its seems like duh.

But what was their base fuel? Pump gas? Remember my normal fuel is VP 110 octane race gas. And I'll be running something like VP Q16 when I want extra power.

it doesn't have to be used purely for octane boost either. it cools the intake, and cooler air no matter what engine you run in, is better for combustion

alcoholinjectionsystems.com has a lot of info.

He doesnt really need it, good intercooling and high octane fuel dont really need water/meth injection. Plus as long as he keeps an eye on his knock controller while he is tuning, there really isnt much to worry about. IMHO, water meth is great for when you want a cheap solution for having a crappy intercooler... When you have a big-boy intercooler, returns become diminishing...

Ordered part #15100-74030 to do a comparison to the ATS oil pump I purchased. When it comes in I'll post my findings.

is it maybe possible ats port the pump aswell? i have heard of that being done to other engines oil pumps?

im curious on your opinion of why your block cracked?
i read a post that suggested our block crack due to nucleate boiling that occurs when the engine is shut off and the water become stagnate. you said yours cracked at the end of the reinforced casting which would disprove this argument. just curious on your opinion?
reason is i plan on running and electric water pump to try and prevent localized hot spots on shut down and therefore minimize the chance of cracking a block (gen 2). but it may not be needed if thats not the real problem

mine cracked while I was driving. I was letting my friend drive and he was in 3rd gear and floored it starting at like 3500rpm. He revved it to only like 6500. From there it was normal driving and like 5 minutes later my lower radiator hose blew off. (I have a sealed coolant over flow so it's legal for the track which I need to change around for street driving). At that time we thought it was a freak thing. Walmart was next door so I walked and got some coolant. While my buddy that was cruising with us went to get some tools. Put everything back together and started to head home. 5 minutes or so later the hose popped off again. put it back on and made it home.

Thinking the pressure in the coolant system was from a bad head gasket. I ordered L19 head studs and a new head gasket. Took it apart to find the crack in cylinder #2

Image

So my trip was a maybe 1-1.5 mile drive to culvers. Parked and ate. Then drove around for 15 minutes calm and normal. Told my friend to floor it. did a 3rd gear pull. Drove like about 5 minutes, then at a stop light my hose blew off. Fixed it, 5 minutes later it blew off. Fixed again and never reved it over 2500rpm to make it home for the next 5 minute drive home. Started overheating too after the first time the hose blew off. May have been over heating between the 3rd gear pull and the first blow off but my friend wasn't looking at the gauge.

Maybe I'm wrong when it happened but that is when i think it did. And we'll never know for sure. It's always just a guess

Dude, sucks to hear about the number 2 cylinder.
Whats your next move from here ?

That happened 2 years ago. That was on a 3S block. Redoing the motor this time with a 5S block half filled to hopefully solve the problem.

Is there a reason for half-filled? How are you doing that? Can't say ive ever heard of anyone cracking a 98+ 5S block ever.
