JDL turbo kit thread
 

I am disappoint that there's been no updates or new threads since the original thread got moved.

And it was a legimate reason for moving it. 17 pages of technical discussion and one mention of pricing; so clearly a commercial post.

My kit is almost ready to be shipped. Much excite.

Hoping mine is too...

My car has the kit on it eqipped with a PTE BB 5558. Working out some tuning issues as of now. I will hopefully have some update here in the next few weeks.

I've been discussing with my tuner the merits of a boost taper tune. I don't want/need more than 220kw/300hp. I'd rather have less power and be able to rape it harder. Plus I've gotten used to drifting it with 150whp, so double that will be awesome.

I'm thinking of running 10-12psi 3500-5500rpm, and then taper it down to 7psi after that. Should make for great midrange torque and response, which is what I'm after.

I give it a week before you go back for retune asking for the full amount

I have a kit coming at some point with a GTX2867R. I'm not planning on running a whole lot of boost on it day to day. I'll probably stick with a 8-9PSI WG spring and run off that most of the time.

The kit is great deal IMHO versus other ones out there. I don't really care about base maps and whatnot, there is no way I would drive the car without a custom tune. The only other kit I'm interested in seeing is the Full Race kit with the Borg Warner turbos but F-R stuff is always $$$.

Manifold was finished up friday :) A few more odds and ends and the UEL's will start shipping this week.

I'm not sure how user names correspond to all our orders but i know we have a gtx2867r coated black kit going to the ATL area boxed up and ready to go on monday!

Yes that would be mine. :D It is shipping via UPS?

I have some other parts to accumulate and decided to finish this autocross season in STX class, so it may be a few months yet before I actually get it installed.

any info on my exhaust?

Yes UPS :) The black looks very good!

We have the overpipe and front pipe done...I was at the shop early today working on the Catback systems...hoping to have catback finalized and ready this week.

Can't wait for mine to be finished up, visiting the shop was just a big old tease for me :bow:

Only limited to around 300whp peak on pump. But can still go for more mid and just taper off.

Nice idea to start another thread.

Fingers crossed my GTX3071R kit is soon to be on its way to the UK. I'm booked in for fitting in 2 weeks time just need to choose 3 inch exhaust system.
JDL guys any joy with your own one yet or are you gonna make me buy the Perrin offering ?

Well I have a tracking number. Expected delivery date is next Monday.

I have almost all the ancillary stuff ordered at this point except a clutch.

Sent you and email :) We will have 3" offerings available by early next week.

:thumbsup:

We don't really advertise it too much but we can get just about any clutch, fuel system parts, radiators, oil coolers, etc for great pricing! Just ask ;)

So you basically want your car to feel like it has a big displacement poor breathing v6??

Yeah, I should run less mid range boost, so it feels like it revs better.

Sure I could run 14psi all the way to 7500. Point is I don't NEED to. I'm happy to run less and look after the motor.

To finish first, first you must finish. My car is being used for drift competitions, not the occasional highway pull. I'm yet to be convinced that anyone has shown the motor is capable of 400whp, unopened, in competition use.

If it can last a season at 300whp, I might push it a bit more. Although, I probably won't.

I would love to be proven wrong, but I don't think 400+ would survive competition.

You realizing that your intentions do not 'look after the motor', right? The power (tq) produced in the midrange at 14psi, which is the rev range you're going to use far more often, is just as potentially damaging as 14psi at 7500rpm. With bulletproof tuning, the peak torque area is going to be the most dangerous for your engine.

You're really not doing your motor, or yourself, any favors by tapering off boost with rpm.

Although partly true, the rods and rod bolts experience the most stress the higher the RPMs climb so by tapering boost it decreases at least part of the equation inducing stress. It is certainly not going to hurt it to do so to prolong engine life. Ideally anything used for continuous competition would be built though.

I'll take the advice of my tuner over some guy on a forum every day of the week.

Haha. I feel you. Good luck. :cheers:

Amen to that! lol

Anyone got their JDL kit installed and tuned yet?

Talk to me next week... =x I am packing parts up to install my motor right now. Should have the turbo in and half ass tuned next week. :)

I picked up my kit from UPS today but probably won't have it installed for a bit. There isn't much to it though, it's just pipes and a turbo. :) Much the same as any other kit.

I'm sooo on the fence about this. JDL has some great rep on this forum and I live in the Phoenix area so it makes sense to run their twin scroll kit and keep it local. At the same time I've been preppped and ready to run the Ptuning kit for about 4 months now and I'm having a difficult time deciding.

Some of the other kits I've seen definitely arent built/made brilliantly.....they arent all made equal....

Well if you do decide to switch to jdl I'd be glad to take the ptuning kit off of your hands :)

Cut beam or dont cut beam...

It's really not much you are cutting, it's not like it's a big structural part of the beam. I'm expecting with my cutoff wheel for it to take about 2 minutes.

Im still waiting on my kit the wait is killing me

Unless you are on a built block with a large turbo personally I wouldn't bother with twin. Call JDL and ask how anal I was about fast spooling... Then consider that I do have a built engine and I purchase the single scroll kit indtead of my originally planned twin. I would rather put the money into other parts of the car personally. P.s. Have we met?


I don't know if they ever posted but I think they now have alternative route piping. Personally I am cutting.

I'd be interested in that. Do you think a single scroll would still have a fast spool with the alternate routing?

Actually even a small cut to the square hollow section would significantly weaken it, they use hollow sections in areas like that because of its large second moment of area for the relatively little amount of weight it has. This makes the beam very stiff and allows it to transfer energy. Removing material from the back will remove valuable material from the tension zone in the event of a collision. That being said I'd still take the cut path, short piping is more important to me personally and id try and reinforce it around the piping as best as possible

It's 2 very small cuts as you can see on JDL's classified section thread. Being a hollow beam if it really bothers you why not just weld back in some metal plates leaving enough room for the pipework.

honestly I wouldn't worry too much about cutting it. Still interested to see numbers and real world driving would work for you
