dewismotorsport's C20LET Corsa gsi

[dewismotorsport]

This turned up today, thanks to bigron for the speedy postage



Looks like it has the same fittings as my lines so hoping it'll connect straight up

[bigron1988]

no probs mate

[dewismotorsport]

Inlet meets car for the first time, still undecided whether to use the throttle bodie as has been known to induce extra wheel spin so may swap down to a Cav V6 one and get a reducer pipe


Needs to be removed, cleaned and a couple of bits modifying before final fitting

[rowland]

looking good ye i heard sumthin bout the throttle body letting in to much air making the turbo spool up quicker is that right ?
any luck in finding a supplier for the plenum parts yet ?
i bought the speedflow fixing off mick for the fuel rail without thinking their to big for mine so we can sort something out if you want ?

[Benn]

That is a cool looking inlet.. Good gains?

[bigron1988]

what tps and throtle cable are you using on yours mate?

[dewismotorsport]

Finally got round to working on my car, first job on the list was to get rid of the dizzy and hall sensor, i've got myself an end cap but had to make a plate to cover the sensor hole as i'm not running one, also had to give it a polish


Then made a bracket to mount the coil pack


No pics of it all fitted up as it was too dark

Went round to Rob's house last night and relieved him of all his un wanted bits, got all sorts, nice one mate


Reason i went round for was to pick up my teflon lined internal fuel lines, I now have enough to do the whole fuel system front to back just need some reducers for my fuel rail and adapt something to fit my original tank set up


Also picked up my .82 hotside to go on my GT3076R


couldn't resist blasting it :help:


Had to drill the holes out slightly as i've used M12 studs on the manifold


Then assembled the lot and fitted water and oil fittings back on all with new seals and washers to prevent further head aches


Bought a few more bits, 3" V clamps


and a bottom and middle tool box for a bargin price of £35 Cheers work


Then got massively distracted after fixing my mates pit bike, had great fun doing laps of the workshop msl:


Finally got on with my inlet, removed old gaskets and opened the top part of the ports out more to suit the gasket, then drilled a hole in for the water return to the header tank as it didn't have one and don't really want any cooling issues on track


Fitted the injectors in, re fitted throttle bodie (gonna run with this one for now and see how i get on as it's an easy change) and also polished it up as i can't help myself :help:


That is all

looking very lush

It's hard to explain really but a vauxhall throttle bodie opens different i.e if you have 50% pedal down the throttle bodie will be open about 30% and progresses better until fully open, where as this one opens 50% pedal 50% throttle bodie and so on, i'll try it and see

pm me some pics of what you've got as i may have them off you, unsure as i've just bought full internal lines but need the fuel rail fittings as mine are -6 and the rail is -8
Still working on the supplyers for the manifold bits but will post up when i do mate

[dewismotorsport]

unsure of gains ben but certainly flow well seeing well over 600bhp, there trumpeted inside as well

what tps and throtle cable are you using on yours mate?

Throttle cable is a cut down gsi one with a fitting soldiered on the end, tps is a siemens item i think i'll get back to you on that one, but i did toy with using a LET one and just make a bracket to hold it in place

[rc]

very nice, inlet is looking spanking

how much smaller is the V6 one?

instead of swapping down to a smaller TB can you not get (or make) a different shaped pulley to fit to this one? one that is more "cam shaped" with a large radius at idle/low openings and then going down to a small radius towards WOT would the be more progressive like the vaux one and you would still have the benefit of the larger TB for flow at WOT



as above. the larger radius means the butterfly will open less for the same amount of throttle movement on the part with the smaller radius

[dewismotorsport]

jordanb7426: that's not a bad idea mate I'll look into it maybe trial and error with shapes etc, the V6 throttle is 64mm inside diameter so would lose 12mm which isn't good tbh

[dearing5]

lovely

[dewismotorsport]

Got the car into the workshop today and made a start trying to get all the bits i've bought onto the car

First job was to pipe up the Carlton oil cooler, fitted up the sandwich plate and made up some hoses, and fitted the filter (cheers Rich )


Next job was to remove all the fuel lines and carbon tank, was gonna take them off intact but soon got bored of that and set about them with some snips and had them off in no time :lol:


Then removed the old tank lid as i modded this to run my old fuel system, un solider the pipe off it, so now need to get a new lid


Have now come up with a new set up using a diesel inner, as it has no internal pump in it


then mocked up the internal fuel lines, need to buy a couple of fittings but think i have got my head round how i'm gonna do it, only downside is that i'm gonna have to loose my sofa like rear seats so the kids will have to walk now msl:


Plan is to cut out wheel well at some point and plate it and then probably after a couple of track days strip the car out properly and turn it into a full on track car in between the odd track and drag days, hopefully have it fully stripped with polycarb windows etc by TOTB if not sooner, then cage over the winter

looking good mate i wanted that fuel system

[dewismotorsport]

looking good mate i wanted that fuel system

Ha ha i should of bought the tank too

[djivesp]

This is awesome That inlet looks sex too
Not sure about the jubilees on the oil cooler takeoffs though, are you sure they're man enough? I had a fuel hose pop off a fuel rail once, this was at about 4.5 bars of fuel pressure which is similar to the oil pressure. Did you flare the ends or anything?

[dewismotorsport]

cheers mate yeah ends are flared so not going nowhere also have decent jubilees (Hi-grip) so should be fine

[dewismotorsport]

Pedal bias box turned up today, only downside is it appears to be missing the rod connecting the pedal and bias bar :cry:
If the guy did put it in the post then it somehow fell out on route worst case i'll buy one but will no doubt make a fully adjustable one


Also made a start sorting my braided fuel lines out, need to get a couple fittings and an extra line made up so will nip to pirtek to have my pants pulled down no doubt :cry:

[corsadonk]

I can sort out your fitting and oil cooler pipes, if you sort out my sump.

[dewismotorsport]

Shame mate I've just been pirtek today and bought all the fittings for the brake lines ;-( can you get the aeroquip ones for the fuel lines cheap as I notice they have them in the catalogue (I assume it's you who works at pirtek?) be happy to do you a sump in return for fittings ;-)

[corsadonk]

Gutted.
I can get them, but to be honest we only get them from Earl's.
Earl's Performance Products UK - Speed-Seal Compression Hose ends

Tell me what you need and, I'll see how much I can get it for.

Ok mate cheers anyway, I'll work out what I need and give you a list

[dewismotorsport]

Had a trip to pirtek after work and managed to pick up all the fittings I need to complete the brake line set up


Have ordered the 3 way junction block for the front will be in next week, to be fair to them they sorted me out a treat once the gaffer have buggered off home, also got them to use some spare line up and make me a new pipe which there not meant to so massive thanks again, need to remove the rest of the rear standard brake lines off will just be using bolt croppers for that me thinks lmao
