Rb26dett Or Rb30dett(26head)

[=premo=]

hi,

i started getting bits together to build an RB30dett with a gtr head and turbos and can still do so. but i can now get hold of the rest of the gtr engine so im not sure as to what one i should build. its to go into an R32 fourdoor.

If i build the RB30 i have to ceramic coat pistons, drill out head bolt threads, modify cam belt bits, change oil pump etc.

If i build the RB26 i have to work out how to move the oil pickup and use another sump due to the 4wd sump (i have the rb30 sump and ill have my rb20 one but i dont know whats involved in moving the pickup??)

comments please

cheers

rb30/26 for sure, its worth the small hassle. My rb30/25 only has 166rwkw's but compared to my old rb20 which had 159rwkw's it leaves it for dead! The 26 head will be even better! i probably wouldn't waste your time ceramic coating the pistons and save that money for something else!

You just remove the diff and weld the 26 sump up.

no great drama if the welder knows what they are doing

id do it all myself, but will the R32 gtr sump fit into the R32 gtst body? i thought the steering setup was different?

Mr RB are you running everything stock or what mods do u have on the RB30/25? as to the ceramic coating, i wont be running oil squirters so for future modding im fair sure ill need it.

any other comments on power/torque.

its a hard driven street car thats on the track for drift/motorkana/sprints about once a fourtnite

cheers

damn, the gf is beating the RB26... well she is rather attractive but still id prefure to take her somewhere nice in a car that has more than 1998cc

if you can do it, then youd be silly not to go for the extra capacity and torque that goes with it.

Dump the gf and spend all your cash on your car... then when you want some just go pick up some chicks in your new improved ride.

I would have to so go the rb26/30.

For the price it costs to pick up a s/h good rb26 you can have a fresh 3ltr with a 26 head.

I'm not one for second slops

Thats probably not the best example to use as far as power figures go, 100 or so kw missing.

rb30/26 for sure, its worth the small hassle. My rb30/25 only has 166rwkw's but compared to my old rb20 which had 159rwkw's it leaves it for dead! The 26 head will be even better! i probably wouldn't waste your time ceramic coating the pistons and save that money for something else!

Dont suggest you destroy sump/diff in which you can get good money for, can buy aftermarket sump/pickup from High Energy. Probably wont cost you much buy the time you sell yours.

You just remove the diff and weld the 26 sump up.

Get in contact with BU5TER, he would be the man to talk to as he has done it, he just doesnt dream about it and then throw his 20 cents in. He will be able to advise you about everything.

hmm, to add to the confusion, building the full RB26dett would cost me less than building the RB30/26. a good friend has the bottem end, i already have everything else ( except forged pistons and gaskets ), i already have the RB30 but still need oil pump, water pump, pistons, gaskets. the 30 will cost more due to ceramic coating, cam belt setup, tuning and other eletrical bits. the RB26 will need a few bits replaced but will be like a simple rebuild, not much tuning needed. either way ill be putting it together with darren from lewis engines so porting, preping rods crank, shot pinging, boaring, honing etc will only take up our time not money.

premo, there's no need to ceramic coat unless you wish to race (track) it, only then would I consider.

The cost of it all will be pretty much the same as you use the same water/oil pump as you would on the 26.

Depending on your use... make your decision. If its motorkhana rb30 all the way, if its purely track work.. well I'd have to say I would go the rb26.

If I were to spend 900 on a nice ATI balancer only then would I go the rb30 for track work.

[=premo=]

i havnt done many track days but i am drifting more and more, well every chance i get now that i have a lil bit of a tyre sponsor.

how hard does the stock RB26 rev (where does the power level off)?
