Frank280zx, i'll be there today with the speedo:) so prepare yourself

Hi Evildky, what do you think about the 3.54 R200 from the zxt car? Its an open diff, then i can also upgrade to rear disc brakes and cv joints from the turbo with the stub axles?

Frank, I think with a good setup and a lite body you can kick some **s of scoobys evo's and Audi S2 look at Garrett76zt and what Thumper did. I'm also looking to put a type of water methanol injecton on the engine. I do like to take it around a track but there are only a few days in a year the track is open for private cars! And autox is not my type of racing, i like to pay 5 euro and do some 1/4 mile runs and talk about the car.

Hey Xander, I met you about one year ago @ the Z&ZX meeting at Assen. We talked about some turbo stuff and my engine. It was a short conversation i remember. @ Tony D, the turbo has some damaged compressor blades. It has got a little shaftplay, only when i'm driving constant at 3000rpm and suddenly accelerate hard it's doesn't make any wining noise. Only at cruising speed and low rpm's. And yes indeed, the blue rustrocket 260z 2+2 was mine. Lovely small world Hi Frank, got your message today. We should visit eachother soon and talk about some stuff. Just get your car(s) running Love to see the Zxr someday.

Thanks everybody for ther reply. Garrett76zt, the problem is that i still have the r180 and u-joints so a harder launch is probably gonna break it. ps love your ride and the engine Tony d, i didn't get this zxt engine from Frank i sourced it myself aswel as another spare turbo engine. I now Frank and i traded a 260 2+2 for a NA engine and other stuff. I'm thinking about buying an Innovate lc1 to connect to the megasquirt i tought Xander did this?. Hope to meet you some day and show my ride (hopefully with more power). Alex v, I'm going to upgrade the exhaust to a full 3" stainless system The other problem for my HP drop could be that my turbo is not so healthy any more, when the engine is hot and your driving and accellerate you hear a squizing and wining noise from the turbo i tink its the compressor toching the compressor house. Could it also be i'm using the wrong weight of oil?? The turbo doesen't smoke, only you can see oil spots on the rear bumper and taillight panels.

Hello all, My car is a 240z with a Euro spec L28ET. After driving for a year with a L26 I was looking for some more performance and I found a complete 280zx turbo 2+2 with a BW T5 transmission. When I was in process of taking the car apart i had the opportunity to buy another L28ET with a T5 transmission and all auxiliaries. I cleaned and painted the engine because I didn't want to take the engine apart (previous owner told the engine had done about 80000km), and put it into the 240z with a later type ZX transmission. The wiring was a bit tricky because I had followed the sticky thread about putting s130 wiring into a s30, only problem was that the euro type wiring use one connector and a small yellow wire to connect to the ignition module. The fuel pump hook-up with the relay also didn't work (its not running for 10sec when the contact is switch on), after the wiring was finished, the car started at the first try!! Only dumb thing I did was putting 440cc injectors I bought from Japan on the engine, it ran but boy it smoked like mad! After some driving around i went to the drag strip with every thing standard and did a 15.9 quarter mile going with 90mph through the traps I bought a mbc set to 10psi went to the drag strip and put down a 14.7 @93mph. I know that it’s smarter to change the down pipe and then turn up the boost. My latest change was a few weeks ago when I built the down pipe. It’s build from steel welding elbows of 3" diameter and a exducer from a custom turbo flange (total cost with my own welding machine only $50). Went back to the drag strip for the final time and did at 10psi 14.35 @97mph, did this on the original 3.9 r180 diff. I know there are some quicker guys on this forum that did better quarter mile times with stock setups in a 240z. Last weekend i went to the Dutch Japanese car brand meeting and i was the only person to show up with a 240z (the Dutch z and zx club weren’t there) so the only option was to go to the Nippon classic club to stand in between Datsun 100a, 1600 and some Laurels. They were very nice persons and the didn't make a problem (He said a 240z attract people). When I walked around i spotted a dyno machine (you can take it to meetings and tracks behind your car) i was there with my brother (also a z nut and drives a 240z) and i told him that for around 50 dollar you could do a dyno run. He was like “why do you need that you got a turbo this don't mean you got big hpâ€. I told him i like to know what the engine would put down with the 3" dp into 2'25" exhaust and 10 psi ! I asked the dyno person if he hade a wideband meter also but he didn't so they strap the z down on the dyno (It was like a dyno dynamic Dynostar or something). Already some people were standing around the car and he did the run. The most funny part was the operator his eyes were getting bigger and bigger, after the result from the first run. It showed around 180 rwhp. I’m like: sir I think you left the handbrake on! he's said: no way! I’ll do another run. I asked if i could adjust the boost (first run was 8 psi) he's like ok but you know what your doing? yesss I’ll put it to 10psi. 2nd run and he put the hammer down and looking at the computer screen and start smiling, put down 216.5 Rwhp and 359nm (264.75lb/ft), crank Hp was 252.6 and 404nm (297.94lb/ft) he told me if i knew what i was doing with the few psi extra!! I told him i still have the emergency relieve valve and nothing going to explode. Only I told him not to rev over 6k, but he went up to 6700rpm I couldn’t get the smile from my face for the whole day, and allot of people ask about the car and engine which was nice because the younger people only know Honda and new Nissan models and other quick rockets. My question to you guys: What do you think of these numbers i have a feeling that it is a bit too positive, could also be wrong. Why does the HP fall after 4200rpm?? I’ll attach the Dyno sheets below. 251.6@5157rpm / 404nm @4113 (crank) 216.5 hp @ 4592rpm / 359nm @ 4068rpm (whp)

Thanks all. I will soon upload some pictures in my album, where you can see my projects. I'm driving very stock now, but my plan is to put on a bigger turbo, because the T3 is making some funny noises like compressor touching the house. Also I want to order megasquirt for tuning and a bigger fuel return line, because the words "fuel economy" is something my Z never has heard of I'll post some dyno sheets of my resent run on an Dyno Dynamic in a new thread in the turbo section (will be an nice thread about difference between US spec and Euro spec turbo etc).

Hello all, First of all I have to say that this is a great Zcar forum and I got nice information about modifying, maintaining and repairing the Datsun Z cars. I’m 24 yo from the Netherlands and just graduate from school as an maritime officer to work as a 2nd mate or engineer. At the moment I’m working ashore because of the projects that I have to finish at home. One of the project is a Fiat 500 Giannini replica that have to get some new paint and a complete build up which I hope to do everything myself. The other project is my 240z racer that was imported from Switzerland and is in need of a total restoration, this car is in need of new frame rails and floor pans, the roof has a sunroof witch I don’t like (I bought a second roof skin) there are some steel sideskirts mounted witch have to be removed and the rear fenders need to be repaired. The main plan is to mount composite fenders and headlight buckets, hatch and some perspex windows to reduce the weight of the car, the engine will be an euro spec L28ET with Megasquirt electronic injection and a Holset turbo or kkk k28 turbo (also dreaming about a RB or 2JZ swap, only a slight problem $$$$!!!). I hope to compete in the local drag race league we have here in Holland, and also do some track days on the circuits. I also have a daily drive 240z which had a L26 engine, and then bought a badly rusted 280zx turbo and put the engine and electronic in my 240z, I made my own 3†down pipe and fit a manual boost controller. I did some runs on the dragstrip and my best time was a 14.353 @ 97 mph. This was on 10psi boost and the car made a big impression on the people because these cars are not so well known with younger people (got respect from the wrx scoobies btw ). Last thing I have to say is that this is the right place for my goals and enjoy reading the threads about the Zcars. Thanks Rick aka Big Z

The s130 gnose from Frank is at my place, and the quality isn't as bad as Frank says. It got some ruff edges, the fiberglass is good quality. Im happy with it. Now only to get it fixed on a s30

Like this one that has been sold on ebay uk?

Hello all, I have read a lot of posts of getting a bigger turbo to replace the stock T3. Unfortunaly, due to all the posts i can't really any info on this turbo. I am currently busy with collecting parts to build my L28 et to +/- 350 crank power goal. I already have an alu IC, 444cc injectors, and now i'm able to buy a good (200 miles) used turbo (from a Ford cossworth). The specs are following: Garret AirResearch Type: T04B28 s/n: FD0102A 465.288.3 intake side compressor: external diameter: 70 mm inside diameter at entrance of the compressorwheel: about 45 mm Compressor output: outside. dia.: 51 mm Inside. dia.: 43 mm Code on compressorhouse: AR60 Code on Exhausthouse: 25JO JW WI 84 A Exhausthouse outlet diameter: 65 mm internal with connection flange for downpipe. (I think the seller measured the diameter of intake and output opening) Bearinghouse: BSAF 1 F 6 The Turbo needs an external wastegate. I really could not find any useful information about this turbo on the Internet, or if it is useful for a Datsun L28. I hope you turbo guys could help me out on this. Rick
