Should and reliably will are two completely different things.

said car spent a LOT of time on the track and was used as a testbed for many of the big turbo systems out there today. it saw constant, daily use/abuse at 6xx power levels, and spent its weekends at the track.

now, anyone can build a dyno queen 2JZ that they trailer to a dyno meet, put down 1000hp on a stock bottom end, then push if off the rollers and back onto the trailer... it's another thing to build an engine that can take 650hp all day, every day under HARD conditions. you can't do that with a stock block.

jsut to give you an idea of what the guy had done to the car, and what he did with it...

well is it true the ve would make more torque than a vg30.
look at this torque may by the oh not so good vg motor. This is my dyno with a bad knock sensor

I can't resist






whats the difference between a 400hp Supra and an 800hp Supra?

maxmaxima91

Im pretty darn sure, read if a few places, that the VG30E has a forged crank also..

you cant say a ve dont make tq even though this was on a 75shot and my A/F was all fuged up at the dyno and i didnt have any jets to fix it

dam thats nice. What does your e/t look like?

subs1000w

never got to the track it seemed like every time i had everything together AKA tires with any tread, a trans with all 5 gears and a full bottle the track was closed for winter and it hasnt run since march but it ran danmk stong especially after i went to a 150 shot shortly after that dyno sesion it had pretty rediculase wheel spin in the 1st 3 gears and i hate to bench race but the estimate most of the people i kept up with in 3rd and 4th was around a 105-110mph trap. i accually gave "boostedmax" a ride when he was in town around last christmas but since it was so cold about 30* i only had about 600psi bottle pressure so it wasnt "quite" as fast as normal but still "got it" pertty good on the on ramp of the highway

About 5-6 years ago I had a 75 shot dry on my VE5 with a JWT ecu, i/e, I know not a good move especially knowing what I do now , BUT at Pomona raceway I ran A 13.6@105-6 Cant remember exact mph..(BTW the VE ran on NOS for a few years with that ecu and never had any problems )

Ford5.0forlife

what i would like to know about these special little motors is how a 75 shot effectively doubles the wheel torque figure?

my jeep doesnt even do that and it makes 225lb ft as low as 2k

If I were doing a serious turbo VE I would just use VG30DETT pistons. It's a drop in deal. Remember I recently used VG30DE pistons in my N/A VE for an easy and cheap CR bump. The VG has a forged crank. There are different length snouts on the various VG/VE engine family cranks depending on the application. The VE has the longest snout (3 woodruff keys) that I have seen from all of these. The VE and VG30DE have 8 bolt flywheel flanges and the others have 6. As far as I know, all of the cranks would drop in each other's blocks and rotate but the snouts are different and then what I mentioned about the flywheel.
No matter how you dice it up, the VE is a better foundation to make power. That doesn't mean that the VE is a more practical or cheaper platform to develop but the bottom line is that VE heads can move more air. I don't know that VG heads can be ported out to flow more than VE heads could. There were those rare VG heads that Nismo used to carry but they required a different intake (fabbed) etc. I don't think the cost on bottom build ups shouldn't be much different since they share bore and stroke. However, the VE does get the beefier rods.

Just to throw my 2 cents in on this, I don't think I would lower compression in the VE unless I wanted a hp/highway monster. The high compression definately makes for a more responsive low end, and it can still handle at least 12psi if tuned right.

Akuma2001

What was the final hp rating on your engine?

I don't know yet. It's only been running for several weeks. I started a thread with all the details on what went in. I have some bugs to work out of the car but haven't been able to do much with work etc. I think the car is fast from sotp but don't have anything to gauge it against. I bought the car not running so don't even know how it felt stock. I hope to see a dyno and track this spring.

I agree with you as it depends on your taste but if I went through the work of a turbo I would want high boost. I don't think response would suffer tremendously with DETT pistons.

personally for a road car i'd probably only go as low as 9:1. 8.5 and less starts feeling really sluggish down low. quite a Z32 and Z31 guys upgrade to 9:1 compression that i've seen.

MrGone

if it was really a problem you could smooth out the combustion chambers, there is still some room for improvement there with the VE. I would do that before lowering the CR

Akuma2001

What type of kinks? I looked back at that thread but you haven't updated it. It is something I am seriously considering aside from going FI. So I wanted to weigh everything. What I do know is anyone with a JWT ECU has to get it reflashed for the higher compression ratio.

Nothing major has happened that I thought was worth posting on the other thread. My coolant sensor went bad so I stuck another in, took care of that. It ran crappy one day so I cleaned the MAFS and it cleared up but sometimes the idle isn't clean and stable. I have a no start problem that will probably boil down to me bypassing the inhibitor relay. I hear one of the front coils arcing from time to time too. I also think it runs a little on the rich side. The engine itself is fine, no VTC noise and no detonation. A lot of times if I lay into it around 3-4k RPM in 1st or 2nd rolling it will spin up to redline, not great for racing but it's fun. The butt dyno feels good but I don't have any numbers now and probably won't until spring. I need a day without interuptions to spend with the car but it ain't happening now. I have been doing mad OT at work and I am trying to finish up a head on a Dodge Crapavan for a customer weather permitting. If my money gets right this coming year I want to go with JWT or I may consider the SAFC-II.

Akuma2001

So as of now you have nothing monitoring your A/F ratio?

No, not for now. I can't spend anything else on the cars until after I recover from Christmas.
