Re: T4 2.5 tdi race engine build goal 300 bhp+
Old engine has been removed ready for the newly re built 2.5 tdi engine.
old engine and box with AXG inlet manifold and exhaust manifold
New engine i have high hopes for in my quest for 300 BHP
New clutch kit has arrived .
New engine and 02g gear box and SMF and clutch 228mm.
Engine and box complete
Engine and box with AXG manifolds on.
Engine now complete ready for install.
Engine now in and painted rocker cover.
Turbo is now fitted Garrett 22/60 v hybrid on quick release V band clamps. Also the exhaust has been raised up to accommodate the new position of the turbo. Also all new braided oil feed and return pipes .
The turbo on the left is a Garrett 22/52v (AXG 150 BHP euro multi van) which was on the van but wasn't balanced properly and failed on the dyno at 188 bhp. The one on the right is Garrett 22/60 v hybrid.This is the one now going on the van.I think this is the largest turbo to be fitted to a t4 not including compound set up's.
The old turbo 22/52 v after the dyno. Luckly all the bits went down the exhaust and not back into the engine.
As the turbo is to big to go in the normal place at the back of the engine ,i have made this quick release pipe which goes from the exhaust manifold up and over the engine for the new position of the turbo .The pipe on the right still needs the T2 flange welding on. 2 x T2 flanges ,2X shallow 90* 63 mm stainless steel pipe and a 63 mm V band exhaust clamp.
After going in and out of the engine bay this was the end result. the turbo now fits lovely in it's new home.
You can see the the original place were the turbo was by the exhaust outlet down behind the inlet manifold.
This is the quick release pipe from the exhaust manifold to the new position of the turbo.
New 83mm induction pipe ,with Garrett 22/60 hybrid turbo and 63 mm pipes to 600 bhp FMIC
The end of the intercooler face in to the engine bay
intercooler now fitted to the bumper cross rail with 2 stainless steel straps with rubber strips to protect both metals from each other.
The intercooler looking from under the engine.
I ordered the bumper which is called an RS4 look a like.Then ordered a intercooler to suit the hole in the front.
While the engine was being done the front wheel arches were flared out to accommodate the wider RS6 19" wheel which protruded more than 30 mm past the arch.
Wheel arches have been finished and painted. 10.10. 16
RS4 look bumper now painted
Rs4 grills fitted from the back side held in with Sicaflex
Rear spoiler has been painted and is being compounded to make it a smooth finish.
Finally getting there now.
Air intake fitted on the wing . I have only fitted this to help ram the air in ,as now i don't have a MAF any more. The air now goes straight into the turbo through the 83 mm induction pipe with no interruptions.
Rear wheels now going on at last.
Everything sits well with the new wheels on
This was my van at the beginning , just a reminder.
Rear spoiler fitted with Sicaflex.
Rear wheels now fitted.
Van now complete . This time fitting the engine,gear box,clutch,turbo, intercooler,wheel arches,wheels,fuel cooler,oil catch can,front bumper, rear spoiler, and DRL'S LIGHTS took 6 months in the shop.Nice to have it back and wow is it quick ? very. Next job dyno and ecu re map after it is run in.So 800 miles between 1500 - 3000 rpm and never on tick over. One step closer to 300 BHP
The intercooler is a bit exposed under the bumper from stones etc so must do something about that or it will get damaged.
So i designed and made a front splitter to fit under the bumper that would also cover the lower part of the intercooler and force all the air that goes through the hole in the bumper through the cooler rather than down under it.
From start to finish. In my mind to sketched out on alloy sheet ,cut, bent ,marked out again, then bent, drilled ,anodized,painted, and fitted.Job done.
This picture shows the air induction .On the left AJT 88 BHP standard from factory.( middle ) AXG multi van (euro 150 BHP )from factory.pipe and air box. ( right )83 mm flexy pipe with cone filter.
Air box's. Left AJT 2.5 TDI 88 BHP and right AXG 2.5 TDI 150 BHP. As you can see the AXG is much bigger and the hole for the MAF is larger too . But it still fits in the space when you up grade.
The 2 MAF's left = AXG 150 BHP right = AJT 88 BHP. The MAF housing's only fit the relevant air box's but the hole in the housing is the same size for the MAF ,but they still need to be changed over as the internals are different.
Luck favours the prepared mind
