cherry red gti turbo project, few more pics - Saxperience

robster247 · 18th March 2013, 17:11

So I got bored of my 1.4 turbo and have decided to go for a bit more power. I had a vts lump sat in my shed and then the ideas went from there really, so got the whole lot stripped and cleaned.

Cleaned all the head and polished up the valves and lapped them back in as there was some pitting on the exhaust valves. I then rubbed down the block and painted as it was very rusty.

I'm currently waiting for my money back off my brother so I can move along with getting pistons and rods so just been doing what I can.

P.s will my vacuum for my dump valve be okay going into the barbed take off on the tb ?

Ratched out my oil feed, should do the job hopefuly.

It should be fine, as it after the throttle body, and its all presurised in there anyways

if it was before the throttle body - then it would be a straight no, but its fine

Looks good, keep going with it.

I'd rub the paint off the gasket faces

Beat you to it, all that's done stanley blade and wet and dry works a treat.

Don't know whether to take the oil feed from the front of the block or from the head, does it matter ?

ThrushMotorsport · 18th March 2013, 19:46

Dosent really make much difference, although from the head is slight easier, but may cost a little more, gives you more of a direct route in my own opinion

I.e atspeed adaptor is iirc £20, the oil feed is about £80 from them, but any hosing specialist can make one up for allot cheaper than that, iirc pirtek are a good one to goto - beleive you have to be an account holder though.

So if done that way, oil feed in total could cost you £60 (adaptor + oil line), just remember if your turbo needs a restrictor to get that into what you want made up

Christ, thought it wouldn't be that much for a short length of stainless hose and a couple of fittings, I have made my own boss which screws into the block and a braided hose which I had on my 8v turbo so may just use that.

I'm unsure if the turbo I'm going to be using need a restictor as I'm not going to use my old t28 but instead a rather large holset turbo haha

ThrushMotorsport · 18th March 2013, 19:55

Yeah, its a fair whack actually, its more of DP parts if im right, so DP prices *sigh*

But then again, they say all the small parts is what makes you go over your budget, so more you can make yourself, the better haha

e8_pqck · 18th March 2013, 20:05

I'd say from the block is better, you want oil to go straight to the turbo not via the cam galleries, its more direct from the front and much better imo.

Good paint choice by the way, looks like a neat and tidy job

robster247 · 18th March 2013, 20:06

Haha yeah the dp stuff is very pricey and not always good as their manifolds warp very badly,

I think I'll use my original oil feed as I don't want to be spending money where its not needed will just be a tad harder to route as is slightly too long. Will get some photos of it now

I thought this but wasn't sure, and surely the oil will be cooler if I take it from the block.

And thanks, can't beat massey red

Holset shouldn't need a restrictor,

What you looking at running?

I have a hx35 laying around the garage I want to put on something lol.

robster247 · 18th March 2013, 22:00

Haha will have a look at it as its currently at my dads house.

All I know is it came off a cummings digger engine, but it makes my old t28 look like a baby haha

HX35 can suck it, you want one of these:

:-D lol! Holset HX60. Needs a new compressor wheel though, as this one has blade damage :-(.

Nice looking build though OP. What's the power target?

Thing is a hx35 may make a tiny amount of useable power on a tu5j4,

Is that your turbo? Could be Interested as we've maxed out the hx40 on my buddy's supra engine!
That hx60 would be insane!

mechsman · 19th March 2013, 07:38

Hmmm, fair point, although I'm not sure how much of the rev band you'd have left after you got it spooled. Yup, it's my turbo chap. Might be better to pm me to discuss, rather than clog the OP's thread.

Rowan · 19th March 2013, 09:54

Nice start! How's it going with the mani?

Hi rowan, I'm having trouble getting the metal made from work as their bending machine is rather large for the angle of the bends I need, they are not 90 degree from a sample they made me.

Will get some photos up in a minute wjen I go down to the man cave

My flange has just literaly turned up aswell, but as you can see the bends just arnt as tight as I'd like them to be, what do you rekon of them ?

Rowan · 19th March 2013, 12:42

Something like this should do it.

You should be able to source pre-fab bends locally, manually bending them would leave the bend too wide as in your pic.

robster247 · 19th March 2013, 12:49

Yeah I seen them but £11 a piece is pricey but I may have to just get them, how much did it cost you in metal ? (if you don't mind me asking )
