Haha...what a guess!

There's a lot of interchangeability with the Garretts...hence so many hybrids. What are your power goals, roughly? If it's 500+, I reckon the T4 hot side might be about ideal...but the compressor might be a touch small. Would be interesting to take a look at the compressor map for it.

I cant find a compressor map for that particular turbo its standard fit on a leyland 510. I want around 400bhp ideally to start with then go from there. Off hand do you know how restrictive a T3 hot side would be?
Adam

Off the top of my head, a Cosworth .63 A/R T3 hotside should see you to best part of 400bhp, depending on the wheel in it. A Volvo housing (.63 A/Rs were only on 240 turbos...740s had smaller ones...either .42 or .48...one is compressor and one turbine, but I always get them mixed up!) with a ATP wastegate housing would be similar.

The T5 guys are generally getting a shade over 400 with the bigger GT28s (71s? 76s? I'm not sure...). I don't know how these flow compared with a T-series, but a 2871 certainly looks quite big...compressor, at least.

I'd probably downsize to a T3 turbine to be honest, at least as a starting point. Being modular, you can always upgrade later with ease if it doesn't suit.

well this is gonna be something special when it's all done

what was the max rating on that IC?, i believe you have the same core size as i do and that is rated at i believe 350bhp?

This update i have mostly been painting headlights and making manifolds.
As photos show i have painted the inside of the headlight bowls which gives the lights a tinted look witout altering the way they reflect the light.

I have also been experimenting with an exhaust manifold. Starting with the NA manifold from a 2.5 20V 850. The turbo hasnt ended up exactly where i want it and im 90% sure i'm going to remake it/ start again. It was more of an experiment to prove it would work. The collector turned out good, but i think using 3" pipe as the elbow after the collector is going to reduce its efficiency. The adapter flange on top is very tempory, it was the only T3 flange i had so i just tacked it on to check things out.

Anyone got any thoughts on the effieciency of the manifold? i.e would it be better to have the primaries longer with the collector directly before the turbo flange??
Adam

Nice manifold making skills, even if it's not turned out how you want it, thats some nice chopping and welding.

Painting the headlight bowls makes them look 100% cooler aswell

it will work, if you see the log-style manifolds it shouldn't matter a bit.. but in theory a straight 90degr bend as collector before the turbo could be a pain in the ass if it gets a weird swirl pattern in it that potentially gets an opposite swirl in the turbine housing

you can't place the turbo near runner 5 and equalize lengths by letting the 2,3,4,5 runner in a larger dip placing the mount upright?; then you should be able to keep some clearence for a 3" downpipe straight back above the manifold and down at the twin brake cylinders (or give it another angle towards the right mirror so it goes down before the twin brake cylinders) the chassisbeams should allow that setup since it gets a bit wider at front, the bends on the piping can be made with a little smaller radius too

i believe the waterpump is on the other left side of the engine; no other obstructions at the right? should give enough room then if the custom engine mounts are placed low enough

Yeh Anjo thats exactly what i wanted to do. The waterpump is on the exhaust side of the engine though.
I am in the process of investigating an audi quattro manifold. I'm trying to buy an exhaust gasket to have a look into the port spacing. As i can buy off the shelf manifolds for them reasonably priced.
Adam

ive been wanting to paint my lights now i know i must do it looks bad ass

I did the painted light bowls thing a few years ago...it looks awesome!

Very good point about the standard manifolds - that can hardly be worse, even if it's less than ideal. They're usually very forgiving of "average" manifolds. It might cost you a bit here and there, but it's probably not worth fretting about.

Same here, been meaning to do it for AGES (theres loads of dust/crap in the one light too so need to clear it out)

Ive been away to long. So many mods I could only dream of undertaking

Cant be long till this is back out on the road, Im looking forward to some you tube videos, and maybe a PPC feature!

Hi everyone i have been slowly working on little parts getting them out of the way, the last few days i have made my delocked tailgate. Seems to of come out very well.
Adam

Very nice, I'm itching to see some stuff turning attached to 340s though. Look forward to this car finished

I finally have the car in the garage to de-panel so i can do all the grinding and welding of the shell with the glass removed. I'm working on the engine bay at the moment because the rain has been stopping me removing the final panels.
Progress however is being made, mainly the little head scratching parts that take hours thinking about then minutes making. Exactly like the removeable bonnet slam panel. I had to make it removeable but useable, retain its strength and be able to slot back in without major work. The end conclusion was two tabs on the body with captive nuts and two on the panel again with captive nuts.
The only reason i need this panel is because of the extra length of slotting the T5 in.
I have also sorted the small rust section on the O/S innner arch and removed the lip that reduces the amount of suspension travel i end up with.
I have also totally stripped the wiring and the engine bay and am looking at modding the bulkhead to allow best fitment of the engine.
I picked up a pair of rust free but dented doors aswell.
And got the final fitment of the intercooler and radiator down aswell.
Any ideas on position for oil cooler????? Running out of space.
