I'm planning on upgrading my turbo setup in the next couple of months hopefully and I'm looking for peoples opinions/suggestions.

RB25DET

Current state

-Custom plenum

-FMIC

-Larger fuel pump

-Jim Berry 3500lb clutch

-740cc's

-Haltech E6K

-Exhaust

-RX7 S4/S5 tubro highflowed

plus the usuals

Currently making about 250rwkw on 15Psi

This is just a rough list of what I'm planning on adding.

-Garrett GT35/40 .70a/r .86 exh 700hp External gate

-Tial 45mm gate

-Unknown what manifold???

-Custom dump

Feel free to give me suggestions non what you think, as I said this is only a rough list. I'm hoping to get 400hp before I have to start building the engine, does this look possible??

Also, when should I be expecting full boost by? 4500??

Cheers, Matt.

Mine, 600HP GT30, .82 rear.

Was on around (17psi) 4200 depending on the gear it was in.

Personally i wouldnt go bigger, it came on late enough, any more and i dont feel it would have been very streetable.

Being you had to be up its guts if you wanted to go anywhere, any bigger and it would be worse... especially in 1st/2nd. Over 120km/h it would hawl absolute a$$, but in the lower gears the 4.XX's dont let you do a lot.

If you play on a streeter, smaller.

If you wanna sacrifice response just for top end power, then GT35.

6BOOST (from calais forums, unsure where else) has awesome manifolds, i got one of his on mine, very sweet.

a mate of mine has a 35/40 with the .86 a/r and that doesnt come on boost till around 4k but he has no cam work either at this stage

To be honest I wouldn't know how hard it was to bolt up because I bought the car with it already installed.

No idea on price either but when I will try and find out because I will be selling mine when the new setup has arrived and is ready to go on. Has not got alot of lag but I've never really looked to see when I hit full boost, I will next time I go out.

2BNVS -

Was that full boost at 4000 or only just starting to spool I'm guessing?

Also what setup are you running to make 352RWkw @ 16Psi?

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
