LeKing Drag GTR Project

[LeKing]

First id like to say im stripping the car from the interior removing anything that would be useless in car. This car will only be for drag use and week-end drive bye. Engine is out (no oil pressure) the compression was 120 cold all across 6 piston some det on 1 the head gasket was cracked and prestone went in oil pan. I smell a rebuild. This is a project so it may take a while but i want to go back to the drag strip by next summer. Im thinking of 2.8L stroker HKS T51RSPL TURBO setup. Parts i have OS GIKEN triple plate clutch AEM EMS Uego with 3 gauges Trust fmic Grex oil cooler relocator oil temp,oil pressure Omori gauges splitfire coils iririum plugs Z32 MAF cusco front rear strut bar rollcage. There is a aftermarket fuel pump i don,t no what it is but it push my 1000cc Rc inj. two lines that go to the pipe at both ends one was tap in close to the firewall. Turbo set up was twin HKS2530 with Apexi power fc tune to 422WHP and best quarter mile was 12.34 at 117mph. Now with the Aem i figured i would have been in the 11 for sure with slicks. But now ill never know cause im rebuilding block so i need advice on what im going to keep on the car and make it light on her feet.

Here is a pic i took in spring 08. I decided to install a front GTR emblem in the grill it looks much better this way.

[LeKing]

This is my motor when i just bought the car in september of 2007. Yes hard HKS piping came with the M's cone filter makes a nice polish look. Notice that they had put 2 filters on the blowby valve covers.hummm interesting!!!

Then 6 days later I went for a few 1/4 mile pull. It did not go as plan. My rear turbo needed to be rebuild. It was spooling really weird almost puffing this was really disapointing but i just knew there was something special with this one.

HKS 2530 yes sir all cleaned and rebuild.


Painted my manifold with high heat temp paint had to cure on top a wood stove they came out pretty good.

Now to put it all back in.






After it was complet i had to check for leaks . Prestone was gushing out from under neat of the car what a mess. Freaking oil leak also made it a pain those press copper washer were used or something it did not seal properly even to this day i still have some leaks because of those copper ring. Installing turbos and manifolds is so a pain in the ass u absolutely have no room and after u have to torque these bolts holly crap . Now i wish i should of pull the motor out u have to drain block anyways. O well there's always next year.

if you have the right tools, turbos are an easy swap! ive done it plenty of times. sucks that you had a problem. if you need help you can pm me.

When i got the car it came with a stupid shift knob everytime i shifted the knob was coming off. I really like the Nismo carbon fiber look so i went with that. I decided to buy a C's short throw kit from Nengun it really shorten the throw and help me shift left handed . I needed a oil filter so i baught a trust oil filter and a nismo radiator cap. That was my first order from japan.





Time for her first oil change AMSOIL

So in the winter i ordered with RHD japan Apexi Power FC,SplitFire coils and a HKS manifold gasket set since i needed to put my turbo's back in. I installed my Innovate wide band gauge were my Omori water temp was since its not working and i can now monitor it on the power fc. Now she's coming along just like i want to just before i go on the Dyno. You'll notice i removed the leather trim from the hand brake and shifter they were cracking so out to the garbage they went.

Here is pics of my engine before and after.

Looks good bud! Can't wait to see this build in a year...
No too keen on those filters on the breather though

[LeKing]

YES TW those breather have now been change especially the one on the turbo side would let blowby over my turbo. Image me and my wife driving along we accelerated pretty good meening it boosted so i see smoke coming from the dash it s like WTF....oil dripping on the rear turbo to the downpipe was burning and was able to creep where the tranny is to the ashtray console. Quite funny now but at the time it's like is there a short or what.HAHA

[LeKing]

So now i was ready to go to the dragstrip until this happen.
PACMAN

OSGIKEN twin plate

Since i had no clue of how much hp this car was making. I decided on buying a triple plate.


looks nice on my car

Since now the car had cost me a few $$$$ to repair i decided to go on the Dyno get her tune right and then next year ill be ready to go on the drag and see how she does on the 1/4 mile.

[GTRADDICT]

Carefull on the 3rd gear!!! triple plates like to eat them lol

[LeKing]

Finally took a day off work to get her to JD Racing on the dyno.


We were all strap in to find out the HP# of my "GODZILLA".


Woops!!! Burn one of the rear straps sorry dude!!!!


Then we finally got what i was waiting for dyno result. This is on stock injectors Z32 maf SplitFire coils HKS 2530.
YouTube - GTR Dyno 422whp


The next morning we arrived and Danny had already installed my Rc eng.1000cc injectors and he was ready to tune.



I finish the day with a big smile on my face since he gave me a drive in his 600whp integra and a few words of advice from Danny. He said the best thing u can do is fix your boost creep by doing this you'll be able to get your full boost by 5000rpm this will change your dyno graph like it should be. I was getting boost creep and only getting like 19 psi at redline. This was cause by my adjustable arms on my actuators were set to long i figured that last year.

422whp on stock injectors is a bit risky imho... they are only 444cc. that powerband looks odd too for 2530s... since they are supposed to perform similarly to 2860's, i feel like you'd expect less of a linear powerband like yours ended up.. check out mine or luckygtr's. i hope the guy that posted above me isnt right

No more nonsense about the shop, if you have a problem with someone take it up via PM. All the posts not referring to this project have been deleted.

No worry, the 422whp is maybe "bloated" where other dynos may show less that 400whp. My car was found as 264whp or something but didn't turn past 210whp on a dynapac soon after. Either way, nice numbers but I'd find out what duty your injectors are at WOT and go from there.

[JDracing]

the dyno sheet that show there that was the first pull at night just too check out the hp no tuning done back in 2008

i doo beleive we change the injector after and tune back after in the morning and gain a tiny bit peek hp but alot in the mid range 30 hp more and 30 tq after the tune at the same boost level

also that graph show hp still climbing that because it had boost creep
