Outer Limits 4x4 Board

It's not the way that I do it (diode) but it will probably work well and give you what you want. Im always available to take a call, or at least will call back. I even have to do this with dealers.... Raising the boost alone on an FTE will do nothing for you if you are that close to boost cut. In ...

Hi CustomTurbos i have a HDJ100r with 1HDFTE How do you get around the over-boost fuel cut on the 1hdfte? I have attempted to raise the boost but I cannot increase it even 1psi or the engine goes into fuel cut. You must stop the ecu seeing 4v. You can do this electroncially or via pressure bleed to ...

Graeme, do you know any way for a home tuner to measure AFRs with out spending big dolllars? The old look for the black smoke :). Other that a wide band O2 sensor and gauge or LM2. yeah, was hoping for something slightly more scientific than looking in the mirror :lol: Actually, this mighht be ...

Toyota builds for 500kkm, its part of the Toyota ethos, thats the secret. Its the same with engines such as the 2JZ-GTE. These have made as much as 950hp at the wheels (dyno queen) on a stock bottom end unopened. Thats quite incredible. Compare that to the much coveted RB26-DETT which gets block ...

Doesn't clicking on them bring up a clear pic?

hey guys ive got a 98 80 series with 275 ks on it and want it turbo , i think its got compression issues cuz its rollingon the gear. i want to do it all properly and just wonder what people have done and what would b the best option. cheers If you can spin some spanner's. Buy a written off 100 ...

Torque/power curve. All uncorrected, at wheels This one shows steady state at 1409rpm. It's making 66whp, 11psi boost and AFR's are still over 17:1. The 1HZzzzzz usually makes less than that at 3400rpm! The EGT's on this setup are great, not so for the other options presented. 1HZ 11psi no ...

You should be able to upload pics directly from your PC now, just click the 'Upload Attachment' button just below the Review, Save, Submit buttons. I wish you weren't in WA, I'd gladly offer my 1HZZZZZ as guinea pig :-) I'd like to know what you can come up with to MAXIMISE output from the 1HZZZZZ ...

Best option, if you have the coin is a 1HD-T or 1HD-FT with a Gturbo, big front mount intercooler and 3" zorst Thanks :-) True enough, selling a working 1HZ and paying $7700 for a good condition warranted JDM import 1HDT is an economical solution when you crunch all the numbers. PJM Performance ...

Three reasons for butterfly on diesel: * Shut down engine (such as 12HT) * Reduce shut down shudder by reducing effective compression ratio (early 1HDFTE) * Assist with egr by creating a vacuum in the intake manifold, drawing the exhaust gas in (such as late 1HD-FTE) Bypass your EGR, remove the ...

Josh, The Garrett line up are very well suited for petrols, but not so much diesels. Two significant reasons are the large disparity in exhaust temperatures and the lower rpm of opeartion. The former is perhaps the biggest factor. If you have clear goals then there is a clear answer. The factory ...

I don't think he is on offroad80s. Custom turbo on here or dieselex here also ToughDiesels on lcool (i think) IH8Mud - gbentink (my first ever forum and a long time ago, so its basically my name, Graeme Bentink) Here - CustomTurbos (was Dieslex - after converting my LX470 to a Diesel 1HD-FTE, which ...

@ Hamo. I dont mind if you don't "like my turbos" as you have said. But... that is quite a statement considering you havent driven one, touched one, seen one in the metal or know what is different about them. I think when it all comes down to it, you want to get other people to agree with your ...

Sounds good, back on deck 17th Jan.

Its a modified CT26. I cant do anything until end Jan now anyways, 4 turbos went out today, thats it, closed shop for holidays

As far as I know, the EGT "adjustment" on Chipit is nothing more than one of those eBay "Auber" EGT gauges with built in relay control. These were designed for Kilns, to shut off the heater element. Anyone can retrofit one of those on any chip. Its a strictly on/off basis though. There are other ...

Ok, well thanks for all the help, but I'm just gonna go for a full dts kit Fair enough, at least it has all the bolt on bits. I do a performance kit for 1HZ with alot better low end response than the DTS kit (hardly even need a boost compensator the boost response is so early - 10psi at 55km/h in ...

As already said, the front piece of manifold from a 1HDT will fit and make it a bolt up arrangement. eBay is a good source for oil feed and drain flange. Make up some oil lines and all is good. Water cooling not required but better to have than not. If turbo has 42040 stamped on the housing, you ...

[quote="TheBigBoy"]Having a few problems with my pump. 1 of the bolts was completely stripped out (the 1 under the compensator of the left that has the spring and pin for the plunger sits against) So its going to cost a bit more and I have to locate another upper casing. Bit of a bummer - some heavy ...

Someone should write up a cad program to do cnc porting. It gets back to the Perfect vs close thing mate, all these changes may make an improvement but the returns are dimisnishing. Doing it "right" is so subjective. Right for your engine and right for a Lemans or F1 engineer is completely different ...

Swaftec is on Outers as "Swaffie", check in Nissan forum as he mostly does the TD42's - The same type pump used in the 1HZ.

The factory turbo does have the 12mm std however the timing ramp is completely different.

Do you have the dyno sheet for the grunter? I know my 1HDT is not going to win any drag races. And with only 100hp currently, I honestly couldnt decide between the 2 ATM. Would eco be better with the grunter? I would want low egts for long life. I plan to do long k's sitting on 100 and loaded with ...

What is the mod to the inlet? My pump being rebuilt as we speak with a few tweeks. 3" exhaust. Contemplating the type of intercooler. Tyres are 35 km2's Gearbox and trans are rebuilt Clutch is new excedy sports For the loss of 9kw I would rather the grunter I think. Its not the whole story, the ...

This is why turbo diesels are soooo hard. A guy over here with 30 years experience (who hiflows ct26's) has told me that the factory pistons wont handle more than 16psi. And Im also currently getting my pump rebuilt and bench tested by a different guy. He wants to set it up differently to take the ...

Cheers for the info all. Will see what i can find in the way of vehicles before i get too excited. Bloke at work has an auto to suit a 100 diesel, ill see if it has a bellhousing as well. Or just get one off pre 1992 80 series with 1HDT. It is a rare A442F thats fully hydraulic so no computer ...

FYI: I took an 80 with a 1HDFT that had the towing spec turbo "Grunter" installed to the local Dyno Dynamics dyno. We ran up 141rwkW on 35" rubber (stock 4.1 Diffs). All exceited, we changed to a set of split rim skinnys to get a "huge number" and roll back up on dyno - there wasnt 1 single kW ...

If the plenum is large enough then the entry point won't matter much. Thats the problem though. How do you make it alot larger? The $1M question is: "How many cylinders worth of volume do we need in the plenum?" I don't know the answer, I'll bet it takes a fair bit of CFD to know for sure. Once we ...

1HZ plus a good turbo and excellent cooling and one of Swaffies pumps could go nicely. Dont expect 1HDT economy though.

As for auto, as far as I know they work of TPS and rpm only, so you should be ok with some mildly clever interception. This is theory - not done it.

I thought welding to the manifold was a no no. Cant stop the pin holes that form. Why cant you just make a completely new intake manifold? I never said you couldn't, but most owners want bang for your buck. I would have no qualms about welding onto the factory cast manifold. At the end of the day ...

What is the mod to the inlet? Cut top off plenum and weld on a aluminium tube to increase plenum size. In theory it evens flow distribution to cylinders and therefore all cylinders run ~ same AFR's Its a sound theory and if I had a 1HDT I would be doing it - sorry to 1HD-FT and FTe owners like ...
