Just to inform everyone, John from Hotshot E Mailed me and said they will have a header ready for the VE sometime this summer. Just thought I'd let you know.

He also told me 5 weeks ago he'd have one available by now. I'm really glad I decided to pursue other options. The Fujitsubo unit is far superior to anything HS has ever made and at roughly the same price.
Originally posted by autoxer7 Did they find a problem with the air/fuel maps and reprogram the ECU?
Not sure. Clark said he may have made a mistake in the programming but I haven't had a chance to speak to him since he flowed the injectors and MAF. I can only assume he made a mistake because Chuck and I had the exact same condition when plugging in our JWT ECU's. I'm crossing my fingers he found an error so he can make the necessary corrections.
You have any pics of this work of art? I'd love to see it, as I am sure others want to as well!

who exactly explained that aftermarket de headers were restrictive?! they are not. the issue is have tuned length primaries which should be longer than a de. stock de manifold will restrict flow. ve exhaust ports are smaller than a de. i have another car running 13.7 full interior with tons of power on a gen4 HS de header. im sure there wont be but a few hp gain with a tuned header. a gen4 HS or an AEBS header with large primaries will work just fine with regard to flow as long as the ve exhaust manifold gasket is used. you cannot use the de gasket. i have a few of the ve gasket left if you need them. $24.95 + shipping.
Are you sure that it is not the other way around? I could swear that if you bolted up a DE header to the VE, that it wasn't the right shape, and there would be an obstruction in the path of the exhaust right as it came out of the head. I could be completely wrong, because I have never seen a VE in person.
i am very sure. i have installed 5 ve's so far. i spent a lot of time measuring for obstruction. and yes the ve ports are much smaller. it is very obvious when you see them side by side.
An SR20DE header gasket and possibly aftermarket DE header WILL CHOKE the SR20VE. I had an aftermarket DE header on the VE previous to the engine rebuild/turbo stage and my VE was in fact being choked by the DE gasket and possibly even the header itself by a 0.25" overhang! This was due to the slight difference in the positioning of the DE exhaust ports relative to the VE exhaust ports. Obviously this not only overrides any possible gains from scavenging effects etc. but also causes nasty amounts of reversion and turbulence which leads to power loss. A shot of the VE head on page 3 (exhaust port side) clearly shows a black exhaust pattern that points to serious leakage problems. The OE VE manifold is pretty good and I should have stuck with it until the turbo stage.
carl was running an early generation HS header with a de gasket. this does have about .25" overhang on the upper section of the port. my previous post states what i have found. if you want to do it for yourself certainly you can. The information on carls site is accurate but it is also pretty old....over a year and a half as i recall.

Couple questions: Couldn't you port the header to get rid of the overhang? If the VE ports are smaller then how do you get a smooth transition from the VE ports and the de header. How does the VE gasket solve the mismatch between the header and the ports?
if you want to attempt to port .25" out of a stock manifold go ahead and see if it works. we would all be curious to see how long it lasts. the ve gasket matches the ve ports. the larger de header will not obstruct flow. it is not a perfect match. there are some turbulence created. however it should't be too much of a problem because the ones i have done so far run great.

So maybe it wouldn't require such a drastic cut. I am just wondering if this is a solution for some people. I may take you up on the headgasket purchase.
Hmmm... Going to be in Japan in a few weeks. Anyone know what I need to be taking a look at? BTW if any of you folks know of tuning shops in the city of Fukuoka Japan let me know. That's where I'll be!!! Hee Hee Hee!!!

Originally posted by Shoes59 Great news. I did a side by side comparison of the Fujitsubo VE header designed for the P11 Primera and the HS header designed for my B13 and it looks as though the Fujitsubo will bolt right up to the cat without any modification whatsoever. The height, length and bends appear to be identical. The only changes necessary will be to relocate the O2 wires which is no big deal.
Hey, Jim!
Did you ever get the chance to install the Fujitsubo header and did it bolt right up without modifications? How does the car feel.... try not to make the rest of us drool.

It bolted right up without any modifications. I was very pleased ;-) The car feels great except for some low to mid throttle surging. I ruled out a/f problems so it must have something to do with timing or perhaps a faulty coil or something. I really got on it for the first time yesterday and it's by far much faster than my full bolt on DE motor. Cruising up hills on the expressway in 5th gear and the thing pulls hard. I'm having it dyno tuned in Toronto in a few weeks and hopefully we can determine what's causing the surging problem. I'll post results later.
