check out GTmotorsports.com they are doing some amazing stuff with VQ's. My 370z will be getting one of there tt kits in the near future.

Well i have not driven the new Mustang but i do own a 10' 370z. I don't think i would get the same enjoyment out of the mustang. Unless you are into drag racing, which neither are suited for, The Z is the hansd down winner. i live in socal and regularly drive my Z up palamar mt and ortega highway and the Z is solid, amazing amounts of grip for a stock car. It tells you when you are getting close to the limit. and in the vlsd, 275 rear tires, and the revsync these car can be pushed i don't think it would be nearly as fun with the solid rearend of the Ford.

the w/g tubing will to be modded. as it is directly in the way of the steering linkage. other than that everything else is great.

here are a few pics of the Stec manifold bolted up in a s30 chassis. Hey Soileau after looking at you manifold from Stec it looks like e might have changed the design a little bit from the original prototype( my manifold), your wastegate tubes are located in different positions. The next time I talk with Scott from Stec i will ask him for sure. your manifold looks like it might be a little bit easier to mod. If anyone would like more pictures let me know, as it is still setup.

there is a ground wire coming off the coil harness that gets grounded on the rear bolt of the rear coil bracket, make sure that this wire is not broken and that the terminal is clean.

i have been running NGKr -8's in my setup with no issues running 23-30psi with t04r. when i get a chance i will try the actual part # shortly.

I ran the Hks gate on this manifold before. it was all right, but i was having issues with boost surge due to out flowing my exhaust housing and w/g. i fixed that issue by using a p trim cutback exhaust wheel. At the time this was all with stock cams. Now that i have the 270deg. 10.3mm tomei procams going in it i think i will be flowing a lot more and i do not want to run into the same issue as before. So i am going to run 2 of fullraces 60mm w/g's. with 1 kilo springs in them. this should allow me to keep the .82 a/r T4 exhaust housing and p trim cut back wheel while taking advantage of the larger cams. All in all i am trying max out my T04R compressor. will it happen i don't know but it should be fun trying. The way the Stec manifold is designed i think it will take advantage of the divided pulses either way with a single or twin w/g the only factor that i can come up with between the two is the flow rates of one gate vs two.

I don't know, but I have not had any problems with them so far. Met and talked with them several times over the last few months.

I pulled this from wikipedia. RB25DE and DET engines produced from August 1993 also featured NVCS (Nissan Variable Cam System) for the intake cam. This gave the new RB25DE more power and torque at lower rpm than the previous model. From 1995, both the RB25DE and RB25DET had a revised electrical system and the turbo charger on the RB25DET had a plastic compressor wheel rather than ceramic. Generally these engines are referd to as Series 2 engines. The Most obvious change to the system was the introduction of ignition coils with built in ignitors, therefore the coil ignitor that was on previous models was not used. Other changes were, different air flow meter, engine ecu, cam angle sensor and throttle position sensor. Mechanicly series 1 and series 2 are exactly the same. In May 1998 a NEO head was fitted, which enabled the engine to be classified as a low emission vehicle engine (LEV) due to their lower fuel consumption and emission output. The Neo head featured solid lifters rather than hydraulic, revised camshafts and a revised inlet manifold, in particular the RB25DE Neo which had 2 inlets going into the inlet manifold. The combustion chamber of the head is smaller, so GT-R-spec connecting rods are used to compensate. The turbo received the larger OP6 turbine. The non-VCT, non-turbo RB25DE was fitted to the R32 Skyline, the VCT turbo and non-turbo was fitted to R33 Skylines and the WC34 Stagea. Early R34 Skylines use the non neo RB, later models use the Neo version. R32 Skyline RB25DE Camshaft duration 240°in, 232°ex lift: 7.8mm in, 7.3mm ex R33 Skyline RB25DE Camshaft duration 240°in, 240°ex lift: 7.8mm in, 7.8mm ex RB25DET Camshaft duration 240°in, 240°ex lift: 7.8mm in, 7.8mm ex RB25DE Neo Camshaft duration 236°in, 232°ex lift: 8.4mm in, 6.9mm ex RB25DET Neo Camshaft duration 236°in, 232°ex lift: 8.4mm in, 8.7mm ex

I have a 220zr sump pan on there. yeah it sucks that i will have to cut up the manifold, but it will be all right. Not a problem, it actually fits very well. I will be posting up more pictures as i go along modding the W/G piping. No, no price cut. I just bit the bullet and bought all the stuff cause it is known to work. i am already going to be fabbing enough stuff for this project.

Hey Colgan! good to hear from you man. Nice build on your Z. i looked threw your thread. Looks good.

Motor mounts intercooler and radiator are all from mckinney motorsports. As for the surge tank, i had it made at a tuning shop on Okinawa, JP called S-Tec. later i will try and take a few more pictures.

Well here is a little bit of an update. I got back from my trip to the east coast and have had some free time to work on the Z. I went and picked up several of the parts that I ordered from Mckinney Motorsports as it is only a 15min drive from my house. I went ahead a dropped the motor into the car to check clearances with my intake and exhaust manifolds. The intake need to be redesigned due to the throttle body flange angle running into the fender. Now the exhaust manifold gives plenty of clearance for the turbo from the shock tower, but i need to relocate the wastegate piping to clear the steering linkage. Also while i was at it i mocked up the radiator and intercooler for clearance checks and to start designing the piping.

well i was a crewchief on CH46e for the last 10 years. I have just over 2000hrs, 1100 of which are logged with night vision goggles. I also have in the ball park of 900hrs crewing casevac missions over in Iraq. This past summer i flew my last flight to Davis Mothen AB to retire the last CH46 of HMM 161. We (HMM 161) are now a V-22 unit in the Marine Corps. I switched over to the Osprey but decided I was done flying i am now just a mechanic.

Sorry that i am so long in replying. busy with work and such. A little too far for me to drive for it. thanks though This sounds good, I will try and find you thread and post more in there. thanks.

So as I started to strip the old Paint off of my car i found that it has been in a accident and the right rear quarter is beyond saving. so now i am looking for a replacement panel that i can weld in. wanting the whole skin from the tail light to the door.

Before i went to power fc i also was using a chiped rb20 gtst 5speed ecu. It works great. On the Z32 ecu controlling the vvt on a rb25, i am waiting on a answer on it from a friend of mine. Now that i am thinking about it i will no use for the cams i used with the rb20 ecu in my rb25 head, since i now have a complete tomei valve train with 270 dur. cams going in. so depending on if you can wait till march for me to get back from the work trip I am on, and to pull the cam outs of my head, I might be able to work something out with you. Should you decide to use a rb20 ecu.

You can use a RB20 harness and ecu on a RB25, but it will be more than just a harness and ecu. RB25 has nvcs, vvt or whatever nissan calls there variable cam stuff, which the RB20 does not. So to make it work you will also have to change the intake cam and cam gear to a rb20 or RB25 N/A intake cam to get rid of the vvt stuff, exhaust cam can stay the same. once all of that has been changed then you will need a means of tuning the RB20 ecu, flash/ rom tuning. Using the above mentioned RB20 Harness, will work on both s1 and s2 RB25's but there might be issues with the s2 ignition preamp box( can't remember the real name) and the coil harness, also with the connectors on the alternator. I am sure someone else will chime in with exactly what the differences all are. If i were in your situation (depending on budget and plans for the motor of course) i would look at something like electromotive's Tec3, that comes with its own ecu harness and wire and the entire engine with that.

well i have not touched the Z since i have been back home for the holidays, but i did get some parts in the mail. below is almost the complete fuel system that i am going to use for the z. starting with a 16gal cell then a 1 gal surge tank feeding two bosch 044 inline pumps y'd to a -10 inline filter and -10 hose up to the fire wall where it will Y to 2 -8 lines to feed both ends of the fuel rail. -8 return to a Sard fpr which will retun back to the surge tank. still need to order the 3 fuel pumps, 1 high volume low pressure pump and the 2 bosch 044 pump to complete the system. now for the second set of parts that i got in the mail. a complete Tomei Rb25 valve train, Tomei 270 dur. 10.25mm lift cams(both intake and exhaust.) set of Tomei springs and drop retainers, and set of solid lifters. The guy also threw in the valves and shims that he was using with them, so on a uncut head it should get me real close to specs with the shimming.

Thanks for the comments. well not a whole lot have changed since i last posted since i am still on the east coast, but today i ordered a bunch of stuff from Mckinny motorsports. i ordered the following stuff. motor and xmsn mount set exhaust intercooler throttle cable radiator. this weekend i am going to order everything i need for the fuel system. I will be back in Cali in a few week and will post up some more progress pictures and such. Cates

The intake manifold is custom, as far as i know i have the only box style plenum manifold S-tec has made other than the one on his own car. For the next month i am on the east coast for work but as soon as I get back home i will take some more pictures of it for you. As for the exhaust manifold, they are great unless he has changed the design, he uses 321ss and last time i talked to him he had yet to have one crack. they flow really well. I will be modding the Exhaust manifold i have to fit 2 waste gates and to make sure that it all clears the steering linkage. A gt35r will be fun on an Rb. I had a friend the was running a gt35r on a sr20det and made something like 500hp and was spooled by 5000rpm, put that on a rb25/26 and you will have a blast.

Well i have been lurking on this website for quite awhile, so i thought i would start a thread on my project. It is a 1974 260z that i bought a soon as i moved back to the states from Japan. Once i bought my house and got the car into my garage me and my wife started to strip it down to bare metal and any rust that i will need to take care of. As we progressed with stripping the car i have found very little rust at all on the whole car, there was some spots that had a little surface flash, but nothing that a quick hit with the sanding wheel didn't take care of. During this i found that the car has been in a accident that i was not told about, both rear fenders had about a 1/4 inch thick layer of bondo on them. i have since removed all the bondo to get a good look at what i am working with. The other side looks about the same. Since this picture was taken i have stripped the rest of the car and have not found any more surprises. Like I said before the car is not in to bad of shape other then the rear fenders. Here is a few more progress shots of stripping the body down, then i will get on with the plans for this car. Cause of the limited time i have to work on the car, i work for a weekend, and then on Sunday night i clean everything up and tack rag the bare metal and spray a etching primer so that i don't get any flash throughout the week. now for the stuff that belongs in this forum, when i came back from Okinawa i brought the motor and drive train from a 180sx that i had swapped a rb25 into. Before anyone comments yes it is a Rb25, and yes i have Rb26 valve covers installed on it. i like the way the Rb26 covers look to the stock covers. basic spec on the motor and the supporting parts; Stock block and rotating parts head has been ported and polished 1.2 mm metal head gasket Tomei Stock cams from a RB25 N/A ( long story) Intake manifold custom made By S-tec in Okinawa Hold just shy of 3 liters Q45 Throttle body Injectors are Nismo 550cc Side feeds Exhaust manifold is a S-tec top mount T4 flanged true divided SS mani Turbine is a T-04R with a .82 a/r exhaust housing and P trim clipped wheel As of right now i have a Apexi Power Fc that i will be using for the computer. I think that sums up everything for the motor. As for the drive train; OS Gikin twin plate undamped clutch R33 5 speed xmsn R200 short nose Diff with a 2-way Nismo Lsd installed Matching shafts for the diff Complete Techno Toy Tuning Rear end swap for the R200. still have a lot of stuff to get to finish this project, but the biggest thing is that i want to do it all myself, or at least as much as i passably came... I hope that you all enjoy watching me try to figure out what the hell i am doing. Later Cates
