My NA-T build finally finished and ready for mapping

Well as title says my build is finally finished after 6 long hard years, its been a tough journey not going to lie and its something never want to do again if honest!! 

Ive done 99% of the work myself and she's fully forged, built head the works, everything is new and upgraded, only parts that's arent new is bare block and bare head plus the cam covers, the rest has been replaced with new and upgraded parts.

In two weeks i will be taking supra to MGT for mapping and MOT and then can finally drive her again since November 2016 when started build, buying new house and covid have definitely delayed the build but so pleased to be finished.

Am aiming for 450-500bhp to start with, then plan is to get fuse box relocated and intercooler pipework tweaked so can refit Nos solenoids and then look at gearbox options...and start pushing power up.

few pics of her from other weekend

Been following this for years. Looking forward to seeing how the nos affects spool when it's running.

I have def taken my sweet time lol, pandemic, buying house and looking into adoption process has delayed her big time, she's just been sat waiting last two years really, then booked her in for March but then had knee surgery which delayed her another 4months.

Same i cant wait to see how the Nos improves the spool, hopefully get her in somewhere quick to relocate fuse box then can refit Nos solenoids as she's going direct port aswell this time.

😂😂😂😂😂 she's built to upset people so thought do it proper lol

Swamps is more than a person. He's a life form.

Still under research quantifying what. But at least you've got another notch on your bedpost lad of the objective at hand 👽

Well thought would give little update....Took car to MGT on July 30th and to say its been eventful is understatement lol.

I hired a beaver tail car transporter and took us about 2hours to get her loaded on truck cause front bumper so low, ended up using 4 scaffolding planks and few other bits of wood but main thing got her on truck without any damage, car did have screen wash wee as now bottle in boot and winched her up backwards, she was leaking out washer jets over carbon bonnet.

Got car all safe to MGT😀

The orginal plan was for Garth to wire up AFR gauge, new air intake temp sensor, boost solenoid, 3 bar map sensor and wire in the R35 coil conversion, and thats where the fun began the kit was meant to contain pins to connect coils up to Link ECU, but they were missing so had to ring whifbitz and get them sent out which delayed it, then Garth was getting no power at ECU and suspected my ECU was faulty so sent it to Link UK to get checked and tested but all was fine with ECU, so garth moved on to the new Tweak'ed wire loom to try trace issues and found a power cable wasn't crimped properly, plus the TPS sensor was wired up wrong.

Garth got all issues sorted and car was finally put on dyno this friday at 1st she made 470bhp at wheels with 360 ft lb torque, and after giving me call i asked him to push her bit more so he took her to 400 ft lb torque and 500bhp at wheels which am happy about as want to protect the W58 gearbox till next year, all left to do now is MOT car and collect her fingers crossed i should have her back this week, cant wait to finally drive my car after all this time.

So good to see this! Weirdly enough i actually thought about your build the other day and wondered how it was getting on. I was hoping you hadn't given up on it but clearly not!

lol trust me have nearly given up so many times and thought so many times of selling her, also just seen your build thread aswell...seems we are both very determined and dont quit, or we both just enjoy the torture and expense

I think its the latter 😅

I hate the expense, but know it'll be worth it in the end

Mate I'll be honest 500hp at the wheels is serious numbers for that w58 if I read correctly.

They don't often see above 450bhp let alone 500whp.

I would seriously consider chilling the power out. I've seen someone with 500hp but you're knocking on the door of 600hp, if I read your post right.

Oh yes serious numbers for a W58 box, I have had bit of work done on my W58 plus got heavy shot gear oil in. 
Am hoping it holds up till early next year when get R154 box.

The W58 boxes are normally killed by torque and are at limit around 430 ft lb so hopefully me running 400 ft lb I should be pretty safe unless drive her like a complete tool.

Yea you read post right shes 500 at the wheels so knocking on 600 door for sure.

Impressive numbers for the Whifbitz kit! Did you get a dyno graph at all?

My only advice at that power level would be to watch EGT's if you can. I cranked mine up and then dialled it back a bit as the EGT's were through the roof on that manifold. It's pretty much an identical setup to what you have and I've installed an EGT sensor on both the downpipe and the 6th bank of the manifold. It gets hot!

Thank you, i am super impressed with numbers shes made, just got her home and she is definitely a little monster and puts down the power very well, understand what you mean about EGT's getting hot when got home took it steady and she was nice and hot lol.

yes got dyno graph she made 507 at wheels, cant wait to take her pod and see what she can do...
