Bolt on turbo kit (18 Viewers)

That can easily be remedied though

So add another $1,000 to the cost?

don't forget the money that you'll get from selling the Pulsar. The kit is complete so drive it like you stole it and if you blow it up, totally worth it.

But, you already know that speed ain't cheap.

We are one of the few that received our WE Turbos, so I definitely understand that speed ain't cheap having just barely dodged a bullet.

I am looking to add forced induction on my other FZJ so I am just doing some shopping.

I have about 7500 miles on my WE Turbo. I'm doing service this weekend I'll pull plugs and take a look. Has been flawless so far no issues, been 3 years.

Strange they don't give you the turbo specs, but since its a pulsar looks like they may have just copied the HD automotive kit with a fancier J-Pipe and fancier dump pipe but a $2,500 mark-up!

I'll add it does look like nice fab work, but who knows if that will be the same as the production kit! Looks to be about 30mins from me though!

I'm kind of surprised you don't see more people just running the HD automotive kit with an internally waste gated turbo. I imagine there's a good bit of people who don't run anything higher than 5-6 psi anyways. Reduces a good bit of piping and then all you need to do is run a downpipe.

Personally I'd also run a water cooled turbo over just an oil cooled one.

there are a ton running the HD kit, they just aren't on Mud! The turbo'd 80 series grp on Facebook is full of em!

Since the borg warner I have is toast I'm debating looking for a same size water cooled alternative. Not sure how much of a difference itd make.

I can't speak for any other manufacturers or anything newer than the 90s but I do know the turbos on the MK2 Mr2 and MK4 Supra came water cooled from the factory. Those turbos lasted forever. Like anything it needs to be correctly installed and I'm sure there's plenty of documentation out there about it.... but then people have to read (heresy i know).

I don't really see the appeal of running an external wastegate unless you're going for more boost than the 5-6 psi. You don't have to worry about an extra exhaust pipe routing and potential cracking either. Unless you just can't get one with the A/R of the turbine (been a long time since I've been in the turbo game)

Did the wits end kit come with a bypass valve or blow off valve? I don't recall it doing so. Seems strange to not want to vent the excess pressure when off boost but perhaps it wasn't that much of a concern?

 

[toyotaaddict83]

Has anyone else running the wits end kit for a while pulled and inspected their plugs recently?

I have, yes. I found a cardboard colored tip. I only pulled one, as this looked to be in good condition.
WE kit with 11k "spirited" miles on it now. No intercooler or oil catch can.

No bypass valve or blow off vale.

I don't recall reading any specific reason for that decision, but the amount of design that went into the system leads me to believe it was not necessary rather than overlooked.

EIDT: I'm not saying the WE Kit was perfect as designed...I added dual catch cans within the first couple months to prevent my turbo from sipping on engine blow-by. I believe I recall the intention of the kit was to mimic the TRD Supercharger kit (7psi boost, no intercooler, no BOV).

On a MAF/AFM vehicle you should run a bypass valve, not a blow off valve. Some turbos (very few) have built in bypass valves. Running any turbo without a bypass valve will shorten the life of the thrust bearings on the turbo.

Agree on recirculating the excess boost back into the intake via bypass instead of blow-off.

Agree that adding a bypass valve prevents premature wear of the turbo, but to what degree the lack of a bypass valve will degrade life is what nobody here knows, yet. I suspect we can reduce the # of instances of the compressor surge with how we drive (not going WOT + full boost --> no throttle)

Also if anyone has added a bypass valve already with their WE Kit, please share pics and part #

I had a bypass on my homemade turbo setup. Was extremely easy to plumb up using a Bosch style hooter valve (which are also dirt cheap and found at junkyards across America).

P.S. This was not my final plumbing layout, but version 1.0 just to show how simple it is to incorporate the recirc valve.

I am no engineer, but I've seen many turbos with destroyed blades from contact with the housing from surging that wore out bearings. Most manufacturers have a bypass valve from the factory on their turbo engines. And it's a very inexpensive part. Just with those things in mind I don't see any reason to avoid running one.

 

[Cruisers and Co]

The Cruisers and Company Turbo Kit comes with a Turbosmart Kompact plumb back valve, its a recirculation type valve.

Do you know of any specs on this unit?
I assume you size BOV and BPV by the volume of air they can flow.

If I remember correctly, at 7PSI we're flowing like 30 lb/min

Do you have flutter/surge when you let of the throttle? I have the WE turbo and have never experienced off-throttle flutter/surge, and I am running 8+lbs of boost. I initially planned to install a bypass valve, but it took a back seat to other mods; it still sits on the shelf.

I think it is the 25mm Turbosmart Bypass, that I have and planned to install.

I will be listing my NIB WE kit shortly... Sadly, this never became CARB approved, and I am in no position to enjoy it.

I'm surprised you guys don't have a valve in place. Years ago a local guy built his own turbo and I went to look at it. No bypass valve and when he got off the throttle after spooling it up while standing still the intake tubing shook violently. after installing a valve it was fine. Not sure about the turbo, but it has to be taking it's toll on the intake tubing and it's joints.

I ran a turbosmart kompact BPV on my built STi making 500 awhp and it worked great. 30 PSI on a GT30 sized turbo.
