Thread: VE+T or DET

I've been considering on getting a VE and slapping an external gated GTiR T28 on it. I currently have a DET, and am ready to slap it in.

The main reason I want a VE is for the smaller cam lobes for daily, and bigger ones for fun. I pretty much want a good gas mileage while being quick/fast. Is it worth the trouble though? The cost is not an issue cause I am planning to sell a few parts to fund the VE.

A lot of people report getting good gas mileage with det motors. T28 should be plenty of power.

I haven't really seen good numbers on my T28 DET before. The concept of VE makes sense as to why it would be fairly gas efficient.

I guess my main thing is, with gas being projected at $5 per gallon, might as well start preparing...

Honestly it all depends on what you want, how much you willing to spend and how far you willing to go. I had the same(or very similar) question a little while back and mostly everyone was saying DE-T, minus a couple people that sad VE-T

If you want better gas mileage I think a better flowing manifold and a larger turbo will do a lot to get you where you want to go with a VE-T i.e. (high 30s hwy). I would look into a t3/t4 hybrid and a log mani. Only thing is its really hard to keep your ac with those setups from what I've seen.

Rich Pyaett used to rock a 98SE with a similar (DE-T) set-up and it was about 350whp and 36-38mpg on low boost daily driver setting.

If I do end up with a P11(looks unlikely at this point but who knows) that's the direction I'd go. At this point though I may just start the saga over with a VE B13.

what kinda MPGs are you seeing? I get 34mpg highway on my lowport DE-T. City is like 25, and tuning is like 5mpg.

i think the VE-T small T28 sized turbo is a great all around resoponsive turbo set up,.

VE do not like the log Manifolds. Known Fact

a equal length is the way to go just gotta have $$$$

My current set up Vadim is what your kind of aiming for , same with my goals

Sr20ve
GTIR T28
STI 550cc Inj
Z32 Mafs

yields yust over 300 hp at 10-12 psi all day . in our cars unless you have a magical tranny stash there will allways be that issue.

thats why i decided on that set up , i wanted fun reliabilty and most important good milage.

on my DE-T RR i was getting just over 32mpg on the HWY
27 or so in the city , hit boost and it went down to 19/23

I was one of the biggest opponents against a VET, since you can make similar numbers with a DET. But after much thinking it just makes perfect sense why VE would be a more efficient motor. Having a small lobe for daily and a big one for fun makes all the difference.



I doubt a bigger turbo and better manifold would help. I have a ported manifold that helped with power but not gas mileage.

On my DET (SE-L) I got 16mpg city and 30mpg highway. On my NA 5 speed P11 I got 16mpg city and 30mpg highway. In my experience both cars got the same gas mileage, so bigger turbo wouldn't help too much. Granted I lived in a part of town with bad traffic. Now I get 18-19mpg on the P11 .

I guess the biggest problem for me is the fact that I have a DET, 8.5CR. If I had a 9.5 I wouldn't be looking to upgrade. But If I'm going to go buy a DE, might as well buy a VE for $700 vs $400 for DE.



16/30 is what I pretty much always got. Did what ever I could to break above 30's, failed and gave up .



Did you build this already or are you still building it? . I'm afraid that T28 will spool up way too quickly on the VE-T. Which means in boost all the time at 12:1 AFR's.

My goal is about 300whp daily. I need reliability over power, plus I'm using a clutch disc, no more 6 pucks here. I do have a p11 trans so that should help in the reliability department.

Its in the works should be a few more weeks or so.

The T28 will spool quick but matched to a VE should be on the money .

The Xtrail VET brings a GT2560 from factory,however it Not identical to the Gtir nut close the Gtir is sligtly larger.

Plus i like using the OEM Gtir manifold no cracks, bends, issues etc. ,

That's what I was thinking too, if VET can get away with GT2560, then a T28 should be just fine and not out of breath.

I have a GTiR manifold myself, with a welded external gate, 38mm... . I'll give a few places a call and see what prices I can get for buying 3 VE's..... 3XVET coming!

Also what's the Compression Ratio of a VE? I keep on seeing mixed numbers.
