Forced induction

Right not going to be a huge post but i thought this may be handy to help others thinking of slapping a tubby on their 25de.

Background.....
Earlier this year i was offered a chance to pick up a very cheap, very clean 33 25de. I grabbed it thinking this would be a great project. After a short period i decided it needed more umph so it was either NOS or forced induction, loving my whistle i decided to add forced induction. I picked up a cheap eton 45 charger and started work, after a bit of thought i decided to switch to a tubby. I started shopping and got the following parts together

series 2 turbo
elbows
downpipe
chargepipe
lots of silicone hoses
actuator
inlet pipe
apexi filter
various hose tails & t-pieces
DET ecu
ssqv and flange
heatshields
turbo oil return
exhaust manifold
various gaskets
banjo bolts
various pipe clips and usual pointless bits
12 inch of my garden hose, yes thats right makes great oil return pipe

What i did.......
The head oil return i placed a t-piece and ran the oil return from the tubby to that, the block had the oil feed so that fed the tubby fine, Water... i removed the piece between the bleeder and the throttle body. 2 pipes ran from each end via the tubby. The actuator pipe i have run to a hosetail tapped into the crossover pipe. Waiting on a front mount i have run a 180 deg silicone bend from the tubby to the charge pipe, ECU i have swapped for a DET ecu, plugs look fine and i've regapped,

Results....
With the above on the DET ecu, on cold is a little rough but once warm runs good although can be a little aractic however once i get my boost set etc im sure will be great. At about 2-3k pulls well, very well infact compared to my last DET id say torque wise im very impressed, of course this is just butt dyno testing at the moment.

All the above on the DE ecu runs great cold and hot, however im sure the map will cause it to be very lean on boost and the last thing i want to do i melt anything etc, thus why i am running standard actuator opening pressure to be safe.

Future....
My next stages are to fit a fuel reg to bring my pressure up a tad and get the DET ecu back in and running right, i need to fit my boost controller to stablise the boost and get my FMIC on and all piped up. Probs a set of plugs is a must too before i kill these ones

heres how it looks for now, and bear in mind its testing until the rest goes in.... This is a work in progress and im posting this to inspire anyone wanting to do this to their rb25de. All in all even at this stage i am very happy with the results, im getting alot more power and its giving me a bigger smile. Once i get my FMIC in and get my charge temps down a bit it will be abit safer.

Parts left to get...
Boost gauge
MBC Valve or a controller
various FMIC pipework
Plugs
consult adapter so i can see whats going on

Looks good, how much would you say it's cost you so far? I think I will still go down the path of getting an RB30 but it's nice to see what can be done with the RB25DE!

Very nice, I have multiple ideas as to what to do with mine but atm lack the funds for many of them. Also its A RB25DE NEO in the R34 so im not sure what complications that would cause :P.

Ike Cerro im curious as to how much would you say its cost so far?

personally i think id be dropping in the 370cc det injectors and running a stock det ecu..

then retard the base timing on the CAS to 10degrees at idle..

is this using the stock NA ecu? i would have thought on the DET ecu i would have to lower pressure as it seems to stutter then pull like its overfueling? I have a FPR on its way to me anyway also....

I also have a DET ecu so whats the difference between the DE injectors and DET? also i presume you alter the CAS timing via the consult using something like Conzult?

looking good bud, Things are coming along a fair way now a few of us have done this conversion and ive never looked back and been going strong for 22months

de injectors are a smaller capacity than the 370cc det ones. I had to upgrade these before even thinking of driving

I have some 370cc injectors if you need'em Ive upgraged to 550cc now ;)
