DRFT 14

Thanks alot guys, I can always depend on getting quick useful replies in these forums . So, the verdict is that a neo computer and wiring loom is needed and other RB alternators *should* fit. Another question, I have an Exedy 5 puk heavy duty clutch that i kept from my rb20det. Mint condition, was only in there for 1 month. Will an RB20 designed clutch bolt on to the RB25 gearbox? I really hope so! Also, will an R33 AFM work with a NEO computer?

Hey there guys, ive just bought a NEO RB25DET motor out of a 1999 GT-T and an R33 25t gearbox to fit into my S14 (previously fitted with an RB20). The motor is missing the ECU, alternator, wiring harness has been cut etc. Ive got a few questions regarding r33-r34 part interchange-ability. Will other RB alternators fit the NEO RB25? What about the wiring harness? And im guessing the ecu will have to be a NEO ecu, and an R33 ecu wont work? Will a DE wiring loom be fine on the DET, or do I need to hunt down a turbo loom? Any help will be appreciated, as im not very familiar with the NEO motors. Thanx guys

Im interested to hear about what sort of revs the turbo begins to kick in. I bought a Master Power T3/T04e 500hp rated and would like to gain an idea about how the turbo will behave on my RB20. Im aiming for 240rwkw. Does youurs do much below 4000rpm?

Thats not actually my engine bay. Its just a pic a had stored in my computer. The car is an R32 GTS-T and belongs to someone on the forum. Cant remmember the username though..

Its interesting how everytime i compare the pic that has been posted and the pic of my car, the piping looks exactly the same. It travels through the exact same spot but still clears the turbo. Thats pretty good actually, I can keep the same bends and not add lag with a 180 degree bend. I also came across this pic which shows another variation, but still uses the "180 degree bend". What have others done about the vacuum hose and the the other larger hose that extends from the plenum into the J Pipe. Can someone please tell me what the use of that hose is for? Im guessing its easy enough to adapt the hoses into the new pipe.....

I have just put together all my parts for a turbo upgrade on the good old RB20 and was wondering what others have done in regards to fitting a top mount manifold with the standard front facing plenum? The problem is the J Pipe, which sits exactly where the turbo will need to be. How easy is to remove the J Pipe and have a pipe fabricated that is routed away from the turbo? What about the vacuum hoses etc on the J Pipe? My engine bay in the pic below will be fitted with a top mount manifold and Master Power T3/To4e. Looking at my IC piping configuration, what is the easiest way to go about doing this and leaving most of the existing pipes? I’m going to go back to the workshop that originally did the IC piping and want to keep costs to a minimum (running out of money!), so id prefer if the IC piping doesn’t have to be redone completely. Will this be possible? This is the mani and turbo that will be installed-

I picked up all my parts yesterday and thought id post a pic of the turbo we've been discussing. Im no expert, but this looks to be a very good quality turbo. This is a pic of the parts together. I am having doubts that the manifold will: - A-Fit in between the motor and strut tower in the S14, as it is designed for a Skyline. B-Clear the turbo compressor housing...I think the comp housing will be in contact with the rocker cover. But fingers crossed!! If that fails, custom fabricated manifold will be the go. Here is a picture of my car, which will be copping a gearbox rebuild, motor will be pulled out and fitted with new bearings and the turbo kit will be fitted! The UNI holidays are gonna be fun....gonna have to work my ass off to be able to affird the work though

That sounds awesome. But that turbo is way out of my budget. The Masterpower im getting is half the price! I know you get what you pay for, but paying half the price for a little more lag but never the less a reliable (as everyone seems to be saying) turbo seems like a good proposition.

Sorry, repost.

The car will be used as a daily driver, weekend night drag wars (Meremere in NZ) and im also very keen on drifting. I figure a clutch kick will easily get the wheels spinning and revs climing. Once traction is lost, lag wont be a problem and the extra power uptop will keep the wheels spinnig. Do I have the right idea here, or should i really be looking for response on a drift car? Most of the top D1 cars in NZ run massive turbo setups on SR20's, RB20/25DET's. Surely they have lag issues to deal with too, but they seem to have no problems drifting with this setup at all. *Hope this doesnt turn into a response vs lag on drift cars discussion, as im still very keen on hearing your opinion and experiences with these turbos . But so far, i think im going to make the order...

Its looking good so far. Im going for a T3/T04e. 60trim good for 240rwkw. Its going on my RB20DET. The price im getting it for is very, very reasonable. And the fact that theres a one year manufacturers warranty on it makes it more appealing to me. Anymore experiences appreciated.

Nope, they are not "the ebay turbos". They are made in Brazil.

Has anyone had any experience with these turbos? The general consensus is that they are pretty good, but I have read a few bad comments about them on the Internet. The supplier was very confident about the quality and promised a one year warranty with the turbo. Anyone have any first hand experience with Master Power?

Car is an s14 Silvia with an rb20det conversion. There was no room for the factory fan that came with the RB so i fit two electric fans instead. One is on the left side of the radiator between in motor and radiator (pulling) and the other is mounted on the right side and between the big FMIC and the radiator (pushing-there was no room on the other side). The fans seem to be doing a good job. The motor seems to be getting plenty of air from the fans and a friend with an RB20 in a 180sx commented that my setup seems to be more effective than his, but he has absolutely no overheating problems. Me on the otherhand cant drive for more than 15mins at a time without pulling over for a while with the bonnet open and fans still running. The surprising thing is that I drove for 20 mins yeserday (hard driving) and it didnt overheat. I had to pull over 5 times within a couple hours of driving today. I have removed the thermostat and that didnt help. The waterpump seems to be working fine as the water in the radiator flows nicely when the engine is running. What could be the cause of this frustrating ****ing problem? I want to enjoy the damn car already after $4k spent on the conversion and almost half a year with the car off the road. edit: Radiator is a two core rb20det radiator, not a non turbo one or anything like that.......

Did you modify the BOV in anyway when you installed the Intecooler and new piping? Check that the hose that goes from your BOV to you intake is still attached securely. Your problem sounds like what my car did before I went over my blow off valve setup.

Cheers for that mate. And for those that asked, ive got a mechanical SPEC R LSD. Tein type ha coilovers, pinapples installed in the 'drift' configeration and 235 tires. The clutch seems ok, doesnt slip at all......I guess il sort out my overheating problems first (overheating even after two 12inch fans installed) then il get onto my 'too much traction' issues. Cheers guys

I decided not to bother fitting the standard rb20 intercooler when I did the Rb20 conversion into my S14. I looked around for a bit and a 600*300*100 Intercooler came up for a good price. I bought that and used 2 1/2inch piping in the "accross the engine bay" configiration. (pics in my profile). Now the question is. do you think this intercooler setup is too big for the RB20DET? Other mods are a 3inch exhaust and an HKS filter. Launching first gear and grabbing second results in the engine bogging down rather than spinning up second gear. Kind of like my SR20DE used to :bs!: . This is rather worrying. I wasnt expecting this. Dont get me wrong, the motor makes really good power and im really happy with it in a streight line. But the main purpose of the conversion was to make the car a better drifter. I dont want traction. Should I have gone for a 600*300*76 and 2inch piping instead? Cheers

Belts seem alright. Il suspected the thermo aswell. Il give it a go. Cheers guys

Here are some pics of the overheating POS

Nope, the motor does actually heat up....alot. But thanx for the input anyways
