L20et Or Rb20det Turbo Onto Fj20

[george.bryant]

As topic and description. I need a new motor. I'm interested in getting a Fj20 non turbo motor that i've sourced for a great price, i can get a top mount turbo manifold for cheap too, will my L20et turbo bolt up? What needs to be done if anything?

Also, will a RB series or L series gearbox bolt upto a fj20? Do i need a different bellhousing?

I was thinking of even maybe setting up a fj20 with sidedrafts :-P

regards, George

Ive heard an FJ with sidedraughts(I don't recall where)....

they are one angry sounding engine...

T3 on L20a too small , plenty have turbocharged NA FJ's - you need to use a modern turbo with emphasis on turbine flow and response . This style of turbo will make more power for less boost (remember its airflow not pressure that gets the job done) and the extra CR pulls up the bottom end/consumption/throttle response .

Side draught FJ's are noisy expensive and very thirsty - cop bait too . EFI is way to go . You can always look into KA24DE's - easier to get bits for and no under bucket shims . One timing chain and the local Navara version uses 8.4 CR pistons . Bellhousing style is SR20 so gearboxes a cinch . North south inlet manifolds came on US S14 240SX . Jim wolf Technology does all the aftermarket goodies . 2.4 litres = torque .

My DR is going NA on sidedraughts in a few weeks

I will get an oil return fitted and plugged and change the manifold studs to 12mm as well though, so if need be I can just bolt my ET manifolds onto the E engine

The L20ET & FJ turbo's were identical in fittment, just the FJ has a .63 rear housing as opposed to L20 .48.

I'm putting the larger FJ turbo on my L20eT just for now.

Disco,

How much better is a VG30 turbo to the FJ T03, as I'm looking into an L28 for the PNV down the track a bit.

cheers everyone!

Adam RSX: 45mms or? I jsut helped a mate sidedraft his 2.0L Rebuilt Rally Pinto Motor for His mk5 S Cortina. It is horrible to get running correctly. What a absolute pain in the ass.

Ghostrider those vg30 turbos kick ass on rb20dets So should be amazing on a L or FJ

Ghostrider the VG30 BB ceramic turbo can be looked at as an RB25DET one with a fair bit larger ARR turbine housing and slightly (tiny bit) smaller compressor and ARR cover . They are drying up fast as someone (red face) let the world know how handy they are . You could use the VG30 item on an L28 easily enough , or use its all important exhaust housing on the RB25 ceramic BB if the L series can support 180-200 Kw . If you could find one another option is the R34GTt turbo as I believe its compressor and cover is slightly larger than the 25DET's cartridge . These made Rb26DETT (206Kw) power from 2500cc but with infinitely variable cam timing . From what I see I think the large ARR VG30 turbine housing with the R33 or 34 cartridge is the limit for these Hitachi ceramic BB turbos . Of these only the series 1 R33's used an aluminium compressor wheel , the later 33/34 used some form of plastic or composite material which generally lets go before the ceramic turbine if over reved . I'd be keeping it down to about 10 lbs boost for reliability - not too foul with 2760 odd cc's .

Sorry to get O/T , much better design than the FJ's Garrett T3 with Nissan exhaust housing . Low friction ball bearings and much lighter turbine , just not a high speed capable turbine .

Cheers A .

I forgot to add if you must use the FJ style T3 I would get it rebuilt using the larger 60 trim compressor which goes with the VLT's larger ARR comp cover . I think I may still have the VL cover and wheel kicking around if you can't find them .

Cheers A .

Other option that you can use is to use the compressor wheel off of the 13bt's hitachi, i know a few boys in adelaide have done that, works quiet well apparently...

Shane,

How's your car doing?

You get to use those parts I sent down wisely.

Cheers,
