I have to comment on this post because its a great place to refresh my head. I had my engine built, but it was a cookie cutter from other similar builds. Almost got identical numbers. This is an adventure and i hope to see this beauty running strong. Best of luck leon. I am following this.

 

If you plan on revving past 7400, do not get a stock Rev-up pump. Guys at Z1 told me 7300 is as high as they recommend, anything past 7500 can lead to cavitation. That's a lot of money to no just upgrade to billet gears and be safe up to 8500 or so.

 

As far as my knowledge goes there are 3 different OEM oil pomps, the DE, Revup, HR.
The problem that the DE has is that the engine is vibrating and that causes the DE pomp to malfunction. They fixed that issue in the Revup by making to pomp stronger. In the HR they fixed the fibrating problem so that pomp isn't that strong compared to the Revup.
Is it a risk to use a Revup pomp, yes but the engine is in the car and i don't wanna disconnect everything So yeah best option will be to upgrade to Nismo oil pomp or even dry sump. But then again my car isn't a track car so my guess would be that this will hold or else we gonna start over again

 

If you wanted to take it a step further you could count the Nismo oil pump and even further Boundary Engineering and Sucker Punch Motorsports both make gearing for the VQ engine oil pumps.

I thinking spinning the engine past 6600 (on purpose) is unwise. The stresses on the components rise exponentially and you're asking for problems and there isnt much to gain past redline - sure, HP climbs but torque drops off.

 

He has big cams, the power should be there but that won't last without a billet gear. That's how Sasha broke one of his engines and why he went to a dry sump. These engines are not set up for revving high, they are set up for torque.

 

Will i do agree with the last part about torque. The difference between my car and that of Sasha is that his revs to 9.000 and was only used on track. Mine will rev lower and will be used on the street with 1 day a year track use.
As far as my research shows the revup pomp is fine for 7500 rpm and the occasional 8000 rpm.
In the end of the day we will see and if it breaks i would start all over again

 

Up to you since you are doing the work and paying for it. Sasha is revving that high now, I'm referring to his previous cammed stock block, as far as I know that wasn't revved as high. If Z1 advise against it I'd say it's a valid argument. Keep us updated on how it holds up though, it'll be interesting to see.

 

Sasha's old engine that broke down was reving to 9000. His new engine is reving to 8000.

So we have started the engine for the first time.

 

it lives!

Looking great Leon. Glad to see you're still working this.

 

Yeah progress is going slow but steady. And after tommorow it will be on hold for another 2 weeks because of holiday.

 

So we got the idle ready. Gonna continu tuning after 2 weeks.

 

sounds mean!

 

Yeah the sound is not that bad for a stock exhaust

 

Update time:

Started mapping the new engine and the break in of the engine. Found some small problems like to high air intake temp and oil leakage. But other then that engine seems to behave great.

 

Photo's from the intake:

The intake now is a 3.5 inch steel intake (can't weld aluminium yet) wrapped in heat reflecting tape with underneath a heat shield.
The 'heat shield' near the filter is a bucket from a local construction market.




Still have some issues with heat soak so gonna change the steel pipe for some plastic pipe to see if that makes a big difference. The other solution will might be a ebay electric intake turbo thingy to give enough cold air to the intake (by blowing away the hot air surrounding it)

 

Yea - gold tape isnt a great insulator ... reflects heat well but it doesnt insulate. I used fiberglass wrap a few years back and it was better than nothing. I would look into fiberglass heat wrap and I would vent the hood. The engine bay gets hot (no kidding?) and you gotta evacuate that heat some how. Hood vents will do this.

 

I use the silver heat wrap, its about half the price and for what it's doing well worth it.

 

Yeah im currently looking at hood vents because the problem only occurs when standing still and by opening the hood the problem flew away

 

May look wonky but if you wanna cheap, you could always settle for hood spacers for the hinges
