Grenade?

[toffy]

hey everyone , i've come to kinda a crossroad with my daily spec drifter thingy , as much as i love the lil rb20 for its unbreakable-ness im getting pretty sick of the severe lack of low down forward motive force.... so i've decided to either whack in a 25det or make it a 30det (just so you know this is kinda my spare car/daily/do while i'm building my other car) . My plan would be to use an average r33 25 head on a 160klm rb30 that's in my umm.. other daily/loaner with a ebay spec T67 and supporting mods . Now , my question is basically , is it worth the extra hassle to make the 25/30 over just whacking in the 25 for an aim of around 280-300rwk , being daily driven (because the n/a auto r31 bores me to sleep) , the rev range i drive in with the rb20 is under 5k 99% of the time so it's not really being thrashed so much. Any advice is appreciated . cheers

p.s i have searched but i haven't really found the answer/s i'm seeking , i'm not so much looking for a power comparo , more of a drivability comparo and/or advice cheers

RB30 will give you heaps of low end grunt esp off boost c/w 25

yeah cheers mate , i think i've pretty much talked myself into going 2530 combo , i have everything except injectors and the turbo itself. I didn't explain myself very well in the forst post sorry , part of my main worry is reliability, i suppose i'm kinda trying to cut corners and 'do it on the cheap' considering it's more of a side project while i'm saving up for my main project (rips bottom end , hopefully with a 26 head with an aim of around 400rwk hopefully reliably ). Do you guys think the bottom end is strong enough to hold around 280-300rwk with only a basic rebuild? or am i kidding myself?

edit: it only needs to live for 12 months

just keep the tune conservative and it should be fine

Do it. Going from a 2L to a 3L there is a HUGE difference in drivability.

It's really not very hard and if you are sensible with the build and tuning, it should live a long, healthy life.

If you prep the bottom end before hand, then the whole conversion can be done in a weekend (I drove in on a Friday afternoon, had a concert Saturday night and then drove it home about 1am Monday morning).

cheers guys , it's a goer by the looks of it , the laurel will be off the road as of this w/e. i won't have it done in one weekend though , gunna sell the 20 and box to fund injectors instead of going for the cheap n nasty std - high flowed . i'll post up a thread when i start

Good luck! You'll love it!
