CLOSED. Kelford Cams for 1GR GB.

Then they will be great performers!

Mine didn't, and their custom specs were all mid and top end. With my transmission's gearing, low RPM acceleration is dreadfully slow. Past that, head is in head rest.

 

This is a grind that Kelford has developed specificaly for the supercharged 1gr.

I have not yet asked for the stock cam specs. (If he's got them readily available)

 

You can ask for comparison reasons. Not really that necessary though. As they have been making them for years now. Just for the wrong market, since not our market. We catalog.

 

So many questions!

That posting from the previous attempt answered a lot of my questions.

@BillDaCat8 are these our cams reground? Or are they new?

Do we have choices on the valve spring rates or do they already know what we need?

I’m a FIRM maybe.

 

New, says in first post. this was my first question as well

 

Missed that little bit there

 

I believe they already have what we need for the correct valve springs. Ill be getting what they recommend. group buy or not these are mine

 

The exhaust are as easy to install as the cam gears, except with the addition of removing the cams. The intake are more challenging, without removing timing cover. I've been at this a long time, and have never done it myself. I have seen one successful member. I will be attempting that probably this weekend. I'll be able to report back what I find.

 

It's too bad that LCE doesn't work a deal to carry these. People would have been installing these years ago.

Regardless, the wave is growing.

I'd fork out for another "turbo" intake set that works with VVT-I. Or maybe I could send those in. Hmmm.

 

Ours are the early 1GR's. The later motor is the roller rocker. It’s in the newer 4runners and FJ's. Dual VVTI, Cartridge oil filter, etc... Tacoma never got that motor.

I'd be in if we can wait til spring.

 

relevant?

Camshafts
The 1GR-FE engine had double overhead camshafts that were made of cast iron alloy. Both the primary and secondary timing chains used pitch roller chains with a pitch of 9.525 mm. The intake camshafts were driven by the crankshaft via the primary timing chain. The exhaust camshafts were driven by the intake camshaft of the respective bank via the secondary timing chain.

The primary timing chain used one chain tensioner (ratchet type with a non-return mechanism), and each of the secondary timing chains for the right and left banks used one chain tensioner. Both the primary and secondary chain tensioners used a spring and oil pressure to maintain proper chain tension at all times. Furthermore, the timing chains were lubricated by oil jets.

For the dual VVT-i 1GR-FE, the cam lobes had indented R profiles to increase valve lift when the valve began to open and as it finished closing.
Shimless type valve lifters/rocker arms
For valve actuation, the VVTi 1GR-FE had shimless type valve lifters. The dual VVTi 1GR-FE engine, however, had roller rocker arms with built-in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms. The hydraulic lash adjuster – located at the fulcrum of the roller rocker arm – consisted primarily of a plunger, plunger spring, check ball and check ball spring. Through the use of oil pressure and spring force, the lash adjuster maintained a constant zero valve clearance.
VVT-i
For the 120-Series LandCruiser Prado and Mk.7 Hilux, the variable inlet valve timing (VVT-i) a 50 degree range of adjustment (relative to crankshaft. Furthermore, the 1GR-FE engine had valve overlap of -6 degrees, intake duration of 232 degrees and exhaust duration of 236 degrees.
1GR-FE VVT-i: Valve Timing
Intake Open -8° to 42° BTDC
Close 60° to 10° ABDC
Exhaust Open 54° BBDC
Close 2° ATDC
Oil passages on the intake and exhaust camshafts enabled the ECU to adjust camshaft advance and retard via:

• An oil control valve (mounted on the cylinder head); and,
• Vane-type actuators on the ends of the intake camshafts.

 

My timing cover needs re-sealing anyway. So, it’s coming off regardless.

I’ve been waiting to do that job until I have all this new shit to bolt on. (Injectors/rails etc...)

 

I'm a pretty firm "in".

 

I dont believe its going to tag anyone since you edited the post.. if you post the list as a new reply, it should tag everyone

 

drat!

I'll try that.

 

Shamelessly swiped this list from the injector GB

I’m also down if we can wait a bit. Too much good stuff going on right now

 

Im also in if we can wait a little while.. Strapped for mod money, but i know this is a worthy one..
