Heya dudes,

Well with the last few weeks spent hopelessly trying to source a decent RB25, I am starting to crack the sh*ts ;) They are few and far between and the good ones are just too much for my 'dorifto budget' :P

Anyways have been looking around and i know those crazy Malaysians, Thailandians love their JZ conversions, so i thought....WHY NOT....

You can source some decent front cuts for about $3K which is heaps cheaper than the RB25's.....

So what is peoples thoughts..... what are bolt ons like with the JZ's???? I am very noobish when it comes to Toyota engines so just after some advice / thoughts from people who know of or may have done this conversion.....

the exhaust and fuel lines will need to be swaped sides under the car for a start...if the Malaysians and Thai's etc have done it, i'm sure there are some sites with a write up on it.

hmm what about 1uz V8, can make some nice power when turbocharged (also doable with stock internals) plus are a light motor and will have heaps of torque!!

DO IT!!

I was actually going to suggest it but didn't for fear of flamming.

Drift Battle magazine is actually going 1J in their S13 project car. Why not email ben ellis and ask him about it. They are going to use twin turbos, those cheap KKR turbos, the smallest ones. Their goal is 280rwkw at a reasonable. boost level. you will need aftermarket ECU like a microtech etc. And you don't need to touch the internals.

I was looking at this but gave up when I couldnt find a language converter to read all the thai forums :P

Would be nice. Similar to 1jz > 180 / Silvia I would think. Drift battle has just started theirs so stay tuned :)

Nah the 1jz would be unique for OZ but the more i look into it the more it seems like the bank will take a hard hit.......

Maybe back to the RB25 drawing board.................... :P

Makes sense in every way... If you do some more research on the 1J you will find it is quite a bit stronger than an RB25... Teflon coasted pistons standard. Much better oil control. Cheapest way to get big power (easy 270+ rwkw) would be a 2nd hand jap turbo kit.

I reckon the difference in purchase cost of the 1J to the RB25 may be eatern away by the cost of install and the aftermarket engine management. But even if its the same i'd still go the 1J because when you want more power it will be a lot cheaper. And if you want decent power in an RB25 you need an aftermarket ECU anyway...

Plus it would be worth it for when you pop your bonnet and someone goes "WTF!"

Though if it were me i'd still go 25/30. Especially since you can use most of your original hardware to begin with.

Yeah i know the JZ would get great WTF factor but aint worth it....RB30/25...great but meh too hard basket....

BUT i have finally sourced myself a VERY LOW km's Series 2 RB25DET engine / gearbox package...just when i thought i was gonna throw the towel in...the car gods shined apon thy and showed me the way! :P

Series 2 RB25 + R33 GTS-T gearbox minus the pressure & clutch plate which i don't care about as I am getting a ceramic in neways.

So car should be dropped @ the mechanics this w/end to have the beast revitalised with all her goodies!

List of things to go in -

1. RB25DET :P

2. R33 GTST Gearbox

3. FMIC

4. Splitfire Coilpacks

5. 3" Exhaust Turbo back

6. Ceramic Clutch

7. 2 x Recaro's

8. Oil Cooler Kit

Once that is done, I have some money left over for PFC, fuel pump, injectors & hunting around for bigger Turbo.

So all things going well *crosses all fingers & toes* i should have it all up and running within a couple of months.......

So with the correct turbo choice....2530..GTRS...KKR480... i should have my goal of 250+rwkw....

Will keep you updated on the process!

Catch yas!

PS if anyone has a Z32 AFM lying around....PM me!!!!!

Here is a piccy of what she looks like now....gimme a few weeks and I will repost a piccy with her in all her glory....

Great to hear mate. We'll have to have a NSW meet when you get it back on the road. I think i'm going to be very jelous!! Wish i could afford mods :) Maybe if stuff stopped breaking on my car (last month air con compressor, last week alternator and coil packs on the way out) then i'd be able to afford some. Oh yeah and I now need 4 new tyres for rego next month becuase I keep lighting them up around corners (first rwd car so i'm 17 all over again) :(

Replicate - Mate I am obviously keeping my RB20 & also not using the coiplacks that are coming with the RB25 (using the Splitfores). Apparently the coilplacks on the RB20 may be on the way out (according to mechanic), but do the RB25 coilpacks work with the RB20?? I think they don't, but if they do let me know as I will be selling them. Coming of the engine that has a Legit 24,000km's, so the coiplacks are fairly fresh!

Yeah a NSW meetup would be sweet, just will have to be in a couple of months, as the work may take awhile!

Konect - Your wish is my command :P

Well the engine came across from Japan from an owner with very little driving done, all history of car and the engine sticker / tag showing details. (will see if I can get a copy posted up)

Hey they could be full of BS :P but will find out shortly as I will look over it this w/end...from the photos I have seen it is in VERY good condition.

Anyways here u go...piccy of engine sticker / tag is crapola (phone camera job) but if u look on 4th column down on Right u will see it states 24,200km's..

      Bah! I can't see the point in custom number plates at all. I went to the rego office, fished through a box of "premium" plates (the ones that had the "not as tall" option for the front plate) and picked the one that had a 32 in it. That's the limit of the effort and cost I will put into number plates. The only plate that I'd consider paying for would be 2332, but that's not possible here because it already exists from probably 90 years ago, and it would cost a fortune to obtain it, if it were available.

      Why am I hitting a power wall with my stroked RB25?

      By Kinkstaah · Posted

      After chasing my tail with LS results..... and cheaper than a turbo swap... How confident are you that the dyno is accurate relative to other results? How fast is the car - What MPH does it actually run? Is this similar to what people running this power would expect?

      98 R34GTT 4k engine stumble

      By Spearzy999 · Posted

      Hi mate I am having an identical issue with my 98 R34 GTT. The engie suddenly cuts out under load at about 3-4k, black smoke out exhaust. Almost feels like traction control kicking in. No CEL but still going to check codes later today. Car was sitting in the shed for about 5 months before hand and only idled a few times, took her out with about 1/4 tank, filled up and thats when the issues started happening.  Threw on a spare set of coils/harness and checked plugs which was no help. Recently had fuel pump/filter changed so surely thats not the issue unless condensation in fuel, I just havent had the time to drain it It's running a hi flow turbo, bosch 1000cc injectors, walbro 450L, Z32, Nistune etc... All about 2000km old.

      I always wonder where the obsession with legal/illegal spacing on number plates in the UK comes from. Because it comes up in comments in every UK-based video I see on youtube. From my point of view all of your plates look a bit odd. Just because there are no markings whatsoever. In Australia we have the state that has to be on it. In Europe you get stamps and state logos. Yours look a bit like a throwaway draft that people then stuck with. And attached with blu tack so that it falls off at the slightest disturbance. Not trying to hate, but it's interesting how things are done in different countries. Do you have to follow a lettering convention when choosing a custom plate?

      Hybrid sounds like a supercharger... It's half a turbo, with a belt to drive it! Oh wait, they're just called super chargers...
