My Gen3 build progress... - Toyota Nation Forum : Toyota Car and Truck Forums

Got these today thank to a fellow TN member

- very pleased with the quality and they look NEW! Don't see many scratches or hardly any dirt anywhere to speak of...

Thanks again to Marco for the extra front bottom mounts - I'm sure those will come in handy at some point! Will be upgrading to stainless brake lines eventually so I will make those work with these coils. Next is to get a new preferably TRD RSB - and finding one of those is like finding native gold in Mississippi - it's just not out there

But it will eventually surface at some point!

I HAVE A PAIR of THESE NOW!!!! The second one took half the time to make since I got the kinks worked out of the lathe and got some better TiN-coated cutting inserts which make cutting even the hardest materials a breeze!

All that's left is to drill and chamfer out the lug holes on the right hat to 9/16" and it will be ready.

But the carbon brake upgrade will happen after the coilovers, RSB, 9-lb racing battery and MR2 manual rack are installed on the car and after it's aligned. Then it should be a formidable track beast at that point

And then comes the N/A 5SFE engine build...what fun!

very nice. are thoes ISC or BC coils? colors are similar.

***N/A Camry Sleeper*** · 08-03-2011, 09:16 PM

BC BR - And I understand BC has a more advanced model out now with a larger oil reservoir or something?! I'm happy with what I got - believe it or not I got these for the decrease in half-sprung weight primarily!

Having adjustable dampening and ride height is kinda cool too

You need to tighten up the chassis a bit don't you think?

oopssorryy · 08-10-2011, 08:26 PM

What kind of power upgrades are you looking at?

RichieRichJP · 08-10-2011, 09:50 PM

He wasn't going to do any from the last big discussion we had. He was going to go for weight reduction.

***N/A Camry Sleeper*** · 08-10-2011, 10:32 PM

This is my plan for the engine after the suspension, brakes, steering, sound dampening, and lightening are all completed...figured I'd get the car to handle and stop the way I want it to before I go and add power. I have replaced the front bumper support to tigthen up that suspension Rich!

Let's start with the bottom end and work up:

1. Stock oil pan - no frills here

2. Lightened, knife-edged, and stroked .100" or so stock forged 5SFE crank
3. New 5.555" length BME aluminum rods (going longer rod with longer stroke to preserve the rod ratio)
4. Flex-honed oil gallery and passages (did this last year)
5. Polished all oil galleries to a near mirror-finish with a Dremel and lots of time

6. Custom DLC-coated titanium wrist pins
7. 12.5 to 13:1 CR custom hypereutectic pistons (high-silicon alloy). Pistons will be DLC coated on the sides, ring lands, and skirts. Thermal coating on the crowns.
8. Block bored until it's clean AND NO FURTHER! Maybe .020" but not to exceed .050" in any event!
9. The correct cometic SS head gasket of course
10. Custom titanium 3mm oversize valves - I will turn and reface these on the lathe. Then they receive a 2-step coating, first with TiN, then DLC. The exhaust valves will have the DLC burnt off of the hottest parts but the TiN will remain for anti-wear purposes.
11. Beryllium-copper valve seats, TiN coated. Will use ZrN if TiN isn't compatible
12. Custom head porting and extrude honing - All ports will have matching CFM flow rates. Valve guide extension removed for maximum airflow.
13. All valve reliefs, pockets, etc to be deshrouded. All combustion chambers to be CC'ed to within .25mL. Combustion chambers polished to reflect as much heat as possible (using water injection as well for high CR)
14. Custom DLC coated titanium shimless buckets (only 15 left to make!)
15. Custom .450" or higher high-lift camshaft (as far as I know this has never been attempted. I've seen .406" lift but none higher). Will have to remove material from the head so that the lobes clear!!! Titanium valves will allow for a less-duration, faster-to-close cam profile that will hopefully increase low-RPM driveability. Should be reliable past 9000 RPM (the pistons lose reliability past this point though - but with DLC coatings...who knows????
16. 2JZ-GTE modified adjustable cam gear. If I could find a way to make both cams independent, I would - but no dice yet
17. Stage 2 clutch and pressure plate
18. E153 5th gear swap. May do the whole tranny if I fry the stock trans at a 9000 RPM shift - I'll be ready with a replacement!

19. Custom underdrive pulley set - made by yours truly

20. Jet hot exhaust manifold coatings
21. Obviously a tune from HELL is in order after all this stuff is put together!
22. Got to have water injection - no exceptions. I'm not running EGR with this motor so combustion temps need to be as low as possible at all times.
23. Cold air intake with the upgraded 5SFE intake manifold

24. Lastly - This car needs to weigh 2250 lbs without a driver. If I can get 500 lbs more out of the car it should be a 12 second vehicle. High 12s most likely, and with 250 HP this is absolutely possible. With 275 HP it should run mid 12s. 2.3 N/A liters can produce these numbers, but EVERYTHING has to be working perfectly - this is no easy task and I mean it when I'm taking my time with the build. Another reason why the engine is the last thing to get built. I got started almost 2 years ago and much has changed: Originally was going to destroke the motor to 1.9L with some 6.000" Ti rods, but that didn't work out. Would have been a powerful and economical build, but now I'm leaning for more torque. Longer stroke should help out with the low-end power while the Ti and experimental parts will make the powerband stay longer and grow taller as 9000RPM is reached. Each little bit of friction reduction and weight loss will help - and when it's done it will be one hell of a sleeper. That's the plan, anyway

I have my eyes on this build. Looking good. I might have to do some of your weight reduction on my car but my two Kicker C12's isn't going to help, along with my poly wood rear trunk panels. Its going to be hard finding weight reduction on my car, plus with tne piles of rust :faceplam: But if you are ever in the market to make some titanium shimless buckets for a 5SFTE i'm willing to pay...

Plus i have to find the money for that V6, 5SFE TB manifold upgrade...

RichieRichJP · 08-11-2011, 11:17 AM

Hey, you do know sound dampening will add weight??

EEngineer · 08-11-2011, 12:53 PM

i'm still baffled at the home made rotors

oopssorryy · 08-11-2011, 04:31 PM

0.0 I will watch this build closely.

***Eye8Pussies*** · 08-11-2011, 06:32 PM

those are some sexy sexy rotors....

Bdub215 · 08-11-2011, 07:35 PM

i may have asked before i dont really remember but... after all you've listed your gonna use a 5S-FE head?? it almost seems necessary for 9000rpms to get a 3sge head. but i'm following this build none the less. i'm still in awe over the rotors.

4Cyl'erThriller · 08-11-2011, 09:22 PM

As with everyone else I love this build. Its really a breath of fresh air in the community. I wish you the best of luck with all the experimental technology going into this build. You have taken OCD to a new level but thats not actually a bad thing in this instance...
