RB26's ITB on a RB20det.

[silnismo]

after picking up the 2nd 240sx which had an rb20det i started doing research like a young boy that just discovered porno for the 1st time. Anyways i looked where many of you not venture........NICO! and found this GEM.

Guys name is BrodyGoble on nico and he's is the process of mass producing the adapter along with a kit (fittings, longer studs).

wow, good stuff. Personally I like the RB-Performance FMIC kit, how it looks with hot and cold pipe on same side of interooler, but this is SO much cooler. rep to u buddy

This has nothing to do with any intercooler.

Also the rb26 runners are way too big for a 20. It might work if you have a fully built engine with step 2 cams, and big ports.

shoudl work on a 25 though :)`

actually this has alot to do with intercoolers...now you wont have the ICP running over the head (getting super hot). it can come down the passenger side and u can have a regular intercooler instead of a gay one. plus better airflow for the intake manifold which is another huge plus. i would like to see the dyno sheets to see how much of a difference it makes without changing anything else...

If you read the thread it explains that shorter runners and ITB's are not a bonus on a small displacement engine.
Basically to take advantage you would want to run 2.2 or the 2.4, port head, cams or your usable power band would be extremely high.

i thought about that, however the post here are correct, it would obliterate the torque on the 20. you would be better off with a custom intake manifold, even 26 guys ditch the ITB's for big power and torque. for the longer runners and big ass TB

i would just rather get a RB26

[blu808]

All I was saying was that even though you will have a nicer looking piping setup that is "better flowing" The fact that the rb20 will run like shit will negate those advantages.

Again RB26dett itb and plenum is too big for a rb20.
