James Rear Mount Equal Length Tubular Headers - Test fitted to car

Re: Tubular Headers to keep turbo in stock location

Holey shit guys

Give me a chance to design the crossover pipe

Honestly the turbo mounts as OEM no tricks here.

the secret is all my crossover pipe which is in my head and not on a CAD drawing yet

I will say again, the crossover pipe will merge both banks somewhere (yet to be drawn up)around the back of the motor and then bring it over to the turbo flange somewhere round about where the OEM turbo flange mounts up.

My intention is that the stock intake plenum will still fit

Its not that amazing or difficult its just some pipes welded together


Gah cut me some slack here good things will happen soon

Re: Tubular Headers to keep turbo in stock location

very good work sir, you are making a very good addition to your combo with this setup. I wouldnt be suprised to see almost 50hp over a set of stock manifolds at full tilt with this. yeah yeah "they made 700whp with stock manifolds" ive heard it too, but they could have made 800whp with just the addition of a proper set of hotside parts. Some of the comments in this thread make me wonder if this is honda-tech, the stupid is strong in here

Re: Tubular Headers to keep turbo in stock location

gotcha, now it makes sense

Re: Tubular Headers to keep turbo in stock location

Probably the best idea you have had yet.

Re: Tubular Headers to keep turbo in stock location

only LOL'ing cause I agree. nothing more, nothing less.

Re: Tubular Headers to keep turbo in stock location

Nice work James, good on you. I'd ignore the impatient ones and just cruise at your own pace.

Re: Tubular Headers to keep turbo in stock location

we want moar pics!!1!!

Re: Tubular Headers to keep turbo in stock location

i'd be willing to buy a set. better then the stock shitty manifolds.

also keep up the good work they look sweet. if what you say is true and they actually are bigger in the picture then in real life i would think spool up would be bettered.

Re: Tubular Headers to keep turbo in stock location

I dont see why alot of people are saying it wont boost worth shit or have massive lag because of heat loss. STS remote turbos spool decently and make good power and deffinately have way way more heat loss than these manifolds could ever have. the reason they work so well is because what they loose in thermal expansion they make up for in density. the principal is simple its like hitting a wall really fast and alot of times with a little hammer or hitting it slowly fewer times with a big hammer you get teh same effect. the cooler exhaust charge the remote turbo sees is also denser so it can exert more force on the turbine wheel. there are good and bad arguements for both a short run to the turbo to get the most effect of the thermal expansion of the exhaust gasses and the long run to the turbo with cooler denser gasses being able to exert more force on the turbine. I say great work man owning the redheaded stepchild of the sports car world this is the only way advancement is made someone being brave/creative enough to try something different if it works fantastic if it dosent then lesson learned and someone has developed some fab skills to try something different again that may work. If everyone thought the way some people arround here do we would all still be driving model a fords with 12hp thinking outside a pre determined box is how new things that work are found. hell how do you think the tried and true methods everyone here is stuck on became that way? someone had to try it now didnt they? heck if my work would ever pick back up and i get out of this hole im in i may get to actually finish my car and i will be building a set of manifolds for the det since the extra width of the 4cam heads wouldnt allow a verry big turbo to be put in the stock location.

Re: Tubular Headers to keep turbo in stock location


Wow there is so much wrong with this post.


They will have massive lag because of heatloss and because of the other longer pipes. The rear mount turbo like sts will lag a lot. This is because long pipe from the engine to the turbo, the long intercooler pipe, and the longass pipe all the way to the intake/TB. If you put a Stock T3 way back by the tailpipe with IC pipes to the front with all thelong intake pipes, or put it in the stock location, what will spool faster. The STS will take way longer.

Hitting a wall with a little hammer really fast resembles a little turbo spooling very fast with no lag
Hitting a wall with a large hammer very hard but slow resembles a large turbo that spools much later and slower.

The exhaust gases will not flow faster once there cool down. When there is an increase in heat, there is an increase in pressure. When the exhaust gases cool down, they will not exert more force on the turbine.

Why do you think they heat wrap turbo pipes and turbos? To keep in the heat to decrease spool time.

Yeah, I'm pretty sure where wouldn't be driving little box 12hp ford if it weren't for godsend people like you.

Re: Tubular Headers to keep turbo in stock location

I bought those headers! I still have them. They are in a box somewhere in my attic along with 40 other boxes of unused parts. They are Inconel alloy and are a Greddy/Trust JDM design. Incredibly well made expensive design. Originally designed for the GTP cars. They will not fit our cars, they are designed for a right hand drive car. I wasted nearly $2K on them. What a shame as they are a nice design. I just now read the entire thread and see that James might have a right hand drive car. I know you wanted to create your own, but mine would have bolted right onto your car without a hitch! At least you could have mimic the design. A guy down in Puerto Rico laid down 400 WHP (claimed) with these with minor mods. and an old Wolf tune. The damn steering linkage is in the way on left hand drive cars. Let me know if you need any information from them, I will dig them out and take some better pics.
