Thread: Turbo Manifold Sneak Peak! READY TO PRODUCE!

I think an eql top mount t3 mani would be pretty f'ing sweet.

No offense taken, and your questioning is valid. We just needed to make sure you guys had all the details before anything was decided on. i did not just want to post a manifold and than say alright who's buying. It was jigged up cause that takes only minimal amounts of time to do. We needed to see who liked it, might be interested, ect.... I just wanted to be thorough for production or no production. Not trying to confuse anyone...We still might do something but my car is still being put together and we would like to show maybe some better finished pics with it installed and running to just give you a better idea of what we got... We are not done yet, and yes or no has not been decided. So just be a bit more patient

I've got a question, and this isn't just about your manifold. It seems to be a common thing. Why is the manifold not split pulse? The advantages of this are greatest on 4 cylinder engines (as apposed to 6 or 8 cylinders). It might have been quite a bit more work on this manifold, so that is a concern. Could you not find the turbo you were after in a split pulse design, so there was no need to make the manifold split pulse? I guess show car judges aren't going to care about split pulse manifolds either; another reason not to have done it.

Doing divided manifolds has it's benefits, but you end up with really large turbine housings, and it requires a much more complex runner design. I've made several mani's for Honda guys using the Holset turbo's from Dodge Rams. The turbo's are DIRT cheap, and make some descent power, but versus a ball bearing GT style turbo the added complexity just isn't worth it in my opinion.

There is some arguement about doing sequentially fired split pulse, which is something I'm exploring. This would simplify runner design, making it easier for builders.

There are turbos with split pulse turbine housings and ball bearing center sections.

What's this sequentially fired split pulse all about, and what makes it different from the traditional split pulse design?

Well, granted there are split pulse ball bearing turbo's. My point was, that on the lower pricing scale, the benefits of divided housings and the complexity that comes with them isn't really substantial enough to outweigh just using a GT28RS or something.

Typically, divided housings are fired non sequentially, in that one side gets a pulse, then the other side, then the other side. So essentially it's going back and forth. This has been in line with the common design of a 4-2-1 header where, on typical 4cyl firing orders cylinders 1 and 4 were paired, and cylinders 2 and 3 were paired.

Recently though, several successful manifold builders, and certain racing sanctions have found that sequentially firing cylinders increased scavenging effect. They were basically pairing 1 and 2, then 3 and 4. So with the firing order, 3 fires then 4, then 2 fires then 1, then 3 and 4, then 2 and 1.

My point is, that using this sequential firing system simplifies the manifold building process for divided manifolds. It's something I wanted to explore on the dyno shortly.

I'm sponsoring a SFWD Honda Civic that will be making all west coast events. The new Borg Warner 372, having been deemed legal, will be used. It uses the divided T4 housing. My plan is to make two manifolds, one sequential and one not, and have both tested this summer in succession. It'll be something interesting to see and will answer alot of questions for me.

Hello all,

This is my first post on this site as I was told about this manifold. I own a Pulsar GTIR and am very interested in the manifold. I am looking to use a GT3076R so am in need of a manifold with a T3 flange and pref with an external wastegate. The problem I have is limited space. If, as previously mentioned, the flange could be move further towards the tranny and the external wastegate could exit within a certain distance (I will have to check the measurements between the block and rad), I would be in if this went ahead.

OK so I know there were a few of you out here that wanted one of these manifolds.... So if you are serious about wanting one please E-mail me at [email]Completefab@gmail.com[/email] and we will work out the details I believe the price will be $500-$600 and I will be Back purging now and I will work on one that will work with a stock radiator.

^Now that is sick.........What DP will you be running?

looks good. i'm no engineer, but it seems like very high quality for the price. i'll definitely keep this in mind when i'm buying parts for my next setup. i would most likely be running a full size Koyo, so i'd love to see pics of the new design which clears a full radiator.

also, it seems like if you moved the upper radiator outlet to face the passenger side of the car it seems like it would be much easier to run an upper radiator hose. just food for thought. i wasn't sure what the plans were for the halfie, i'd love to see the finished product. the extra clearance would be nice.
