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.

Replicate - Hey dude!! Mate was Drift Battle that inspired the thought!

Might give my mechanic a call and see what he says...

Just over this whole engine BS.....someone wanna build / source me a RB25/30??!!! :P

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 :)

Konect - Amen to that....been on the sites and my thailandese and Malay aint what it used to be :P

Does anyone know of someone on here that has done this conversion?? I swear i read somewhere.....or not.....

I made a thread about it a while ago if that counts :)

Couple of 180s on ns.com that have this conversion atm. Maybe look em up n stuff.

sorry... think i'm getting a cold or something >_<

DOOOOWWWWIIIT!!!!

Oh so your offering to fund this project........ :D Thanks Dave!!!! >_<

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

Excuse me while i scream .........AAAAAAAAAARRRRRRRR

GGGGGGGHHHHHHHHHHHHH

FFS imports....HATE TO LOVE EM.................

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.

Ando

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!

More details please....

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..

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
