Purchased a 32 GTR afew weeks ago.

It is unregistered but has been complied.

6th cylinder has no compression

Here are my plans for the rebuild.

Looking at sending the engine over east to Lewis Engines.

Will cost $300 to freight it there and back

Basic rebuild will cost $5600 this consists of the following:

forged pistons and rings ARIAS

bore and hone

deck block

cracktest and grind crank

blueprint all clearances

ACL comp bearings

multi layer steel head gasket

reco head

gates race belt

waterpump

tensioners

Welch plugs

reco and modified oil pump

line hone main tunnels

resize rods

new bushes and arp rod bolts balanced

Was then thinking of paying an extra $350 for r33 jun collar

$699 for H Beam forged rods

Will then slap it back in running all stock gear.

After it is licensed i will then look for new turbo setup.

Is it worth keeping twins or going single?

Was thinking of finding some N1 turbos

What do you think of the setup?

Wanting to pull around 350rwkw maybe upto 400 late next year.

Will the bottom end listed be ok to handle that?

I know i shouldnt build an engine then stick stock turbos on there but i need to get it licenses asap.

Will keep stock boost untill i can replace the turbos/hi flow them.

Could even stick a single gt30/gt3540 on there.

Will be tuning stock ecu as i have her hardware and software to do it

If you are looking for 350- 400 rwkw it is better to go something bigger than the N1s. If i'm not wrong, N1s probably give you 320 or 330 rwkw.

With your engine build, 400rwkw shouldn't be an issue.

Ever thought of getting an aftermarket ECU instead of re-map?

BTW, where's Lewis Engines?? :D

ATM im more worried about getting car licensed.

I would be happy with just over 300rwkw for quite awhile.

N1's seam to give good power they are bolt on and steel wheeled.

any power goals over 300rwkw will not be for awhile id rather a very streetable car than power monster.

I real time tuned on old 32 gts-t and found the stock ecu a joy to work with.

If GTRs in Japan can run megga power on stock ecu's i dont under stand why more people dont give it a go here.

The build sounds awesome :D

I've heard only great things about the N1's, both street and drag/circuit.

They're almost as responsive as the stock ceramic GTR turbos but can make over 300awkw.

If i was you i'd seriously consider N1's (or a Garrett/HKS equivalent with similar A/R's).

The High-Octane R32 GTR, before it was totally rebuilt, ran N1's and pulled 400awkw from memory. Obviously that's a race engine with mega cams, but shows what the turbo's are capable of.

Hey man

I had a similar engine rebuild, after this i purchased a set of R34 N1's and saw a very healthy 303awkw, with nearly stock everything apart from

full exhaust system and an apexi power fc. Couldnt say enough about the N1's, so responsive and street friendly. From what you're saying

they would sound just the thing. Good luck.

:P

For 400rwkw I wouldn't want to be using a reconditioned stock oil pump. Go Jun, another $1000 (greenline.jp)

Also, what about Valve Guides? Head Studs? Sump Extension?

I personally wouldn't rebuild a 26 and retain the standard valve guides, seen and heard of too many guides dropping and taking a brand new motor with them.

this round of mods is puerly to get car registered

things like oil pump and head work will be done in time.

will not be chasing any real power over stock until turbos get done even then it will only be very small increase.

400rwkw is a long term goal

if you just wanna get the car running so you can get it on the road, probably your best bet would be to buy a motor from a wrecker. it would turn out way cheaper in the end. there would be no way you would catch me bolting on stock turbos to a fresh motor. you can get 300awkw+ out of stock motors easily. id say only build the motor if your chasing high power figures.

im not against rebuilds though. half way through my 2nd!.... :D

i am chasing more than 300rwkw but not at first. no point buying second hand engine as i could put that money straight into the bottomend rebuild like i plan on doing

I will get stock turbos inspected before putting them back on if there not the best ill wont drive it untill i can get the n1's or somethig similar.

    • 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)?
