Thread: VET build Pics.

I plan on taking it up to around 20psi. The manifold is the new protech design, so backpressure is reduced over a simple log. I think the smaller overlap will help with reversion from backpressure, but the extra backpressure will add to pumping losses.

I am still running a cat also, I still want to be able to hit 400whp on pump gas. I don't know how reasonable this is, but I did 265whp on 10psi without the cams switching on my old jwt program. This program is at least 20hp stronger with the z32 maf than the old program with the lightning maf.

I plan on keeping the jwt and adjusting base timing and using the nismo fpr to make minor fuel adjustments. The JWT loves 10-10.5:1. I think I could lean it out to around 11.8 or so and still be safe on 17* timing. I guess I will have to play with it to find out.

But the bets are on. One of my friends needed 23psi to make just over 400whp in his celica all trac (rear wheels disengaged) and he has a eql mani and a gt35r with cams. But his upgraded cams are 9mm lift vs the VET 11.3/11. He is betting I am nowhere near 400whp til 20psi.

If my buddies disco potato can lay out 340ish on 18-19psi than this big turbo should be cabable of at least 375 right?

Great built... so far so good!! It will pull like a beast!! What's your time goal for 1/4 mile??

looking to hit a 12 flat. Or get a pink slip (kicked off the track for too much speed). Either way I will be happy.

why are you using a GTIR oil pump instead of a VE?

Sweet build!

And O/T, C16 doesn't exist anymore. It's now called Q16, IIRC.

i definitly hink you wld have alot to gain with a calum realtime ecu or a stand alone, 10:a10:1 5:1 is really rich, 11:8 is really optimum 12:1 is great but 11:8/9 is safe

as far as how much this turbo can make vs the disco, it realy depends on how well your parts flow with eachother, but i dont think yuo should have any problem with 400whp

the VE pump is extremely hard to get ahold of new. I waited for 3 months to see if Greg would get one but he never got any. So I went with the next best thing. The GTiR pump looks really good and is a very easy to find alternative to the VE pump. I have two fried VE pumps laying in the shop in pieces.

I would have gone with the VE pump, but in all reality the Gtir is probably just as good, the gtir has to feed more oil out than the VE.

*edit* The VE pump is a better design. Look at picks. Though both are high flow pumps, the VE pump looks like it has better anti-cavitation features for higher revs. If you are building for a high revving motor VE pump is the best way to go.

no housing upgrade ??? on the turbo yet ...

Yeah you will be able to play with the FPR, and 17* base timing should be alright, but i don't like how conservative JWT timing table in their tunes are. I understand these are mail order tunes, but this is what causes the issues. With you leaning out to 11.8(which is a solid spot) but not being able to build more timing into your tune you will not be able to get near what you could get with a custom tune. So will need more boost to reach your goals.... as opposed to less boost with a better tune and still hitting your goals....and as you increase boost detonation becomes a major issue especially20+psi on pump....but 375whp is certainly attainable on pump with your set-up

Here you can see the outside differences in the GTIR pump and the VE. These protrusions tell a small story on the outside, but the differences and improvements on the VE pump become apparent when you look closely!





On the GTIR there is only one oil hole here.


Here is the Ve pump. You can see 2 oil holes in the same place


Take notice here on the back. The oil inlet on the VE has roughly a 30* angle slope in it right about 2" inside the pump. The GTIR hits about a 80* angle. The flow characteristics of the VE pump are improved here. Too bad I couldn't find a working VE pump.


Here you can see a slope for the oil to smoothly enter the pump.


But on the GTIR pump you can see the oil practically hits a wall upon entry.


You can see from the outside of the GTIR pump the sharp turn in cast into the pump.


So the differences are noticeable but considering how many 90* angles the oil has to pass through inside the block, the flow difference is negligible. Once the oil comes out of the pump it has to turn 90* 2" into the block in order to go through the oil filter housing and another 180* to get back into the block. Go ve pump when you can, but if you can't you prob won't notice a difference unless you are revving really really high.
