Hi lads,
Been off here for awhile debating getting rid of the G but after a long think it would be stupid after putting all the hours in rebuilding it and then getting rid of it.
My problem is I want more power (don't we all) Off the top of my head my spec stands at
Full blend charger with abit more porting
Gt inlet manifold
4-2-1 exhaust mani
A little porting on the head and both manifolds
65mm pulley
Decat
Chip to suit apprently according to last owner
Helix organic clutch ready for more power
I was wondering how I could get a bit more power without going turbo.
I was wondering if switching up to G60 green injectors and getting a decent map then add a bigger I/C would get some better figures??
If you have any ideas or advice would be greatly appreciated
Jake.
not necessarily, standard injectors wont be an issue till you are well past 160bhp. Would have thought that was about 150-160.
getting a decent map may well open up a bit more power in comparison to a generic chip.
what sort of cam could you put in there?
That's what I thought hayesey unless it was definitly going to be over 160 then greens weren't necessary.
I might look into it because you can pick up greens pretty cheaply can't you??
How much is a map at the moment??
XRich. I wasn't really keen on camming it unless I got uprated valve springs and followeres to go with it and that's more ££££
But you dont need greens, you're not well past 160bhp remember. Or even near to more than likely.
agreed they will make zero difference to the power. But if you are going to have a remap then I'd put greens in at the same time in case you need them in the future
What kind of things could I do to get a bit of extra power.
If its big money I may just start investing in handling.
51mm Throttle Body matched to your GT inlet would help. Biggest thing I would say would be the map - if your chip isn't very good there could be some great gains there.
As above - map can make a good difference. Unfortunately apart from that you're scratching at little gains without going turbo IMHO.
Thanks for the advice lads,
PPP does mapping doesn't it?? If so does anyone know how much they are??
G-Spot (Jason) did the following work to K340 JCA
Schrick Camshaft with vernier pulley.
Ported/flowed head, new valve and guides, gaskets, seals at engine rebuild.
Thinner metal headgasket,
GT manifold port matched to head,
51mm throttle body,
G60 green injectors,
Jabba induction kit and heatshield,
Boost return mod,
PSD 4 branch exhaust manifold and full PSD 2 box exhaust system(Fully heat wrapped) with receipts for around £700,
Helix Organic Clutch,
RPM Tuning Cast Alloy Sump (no longer make these),
Mocal Thermostatic Sandwich Plate with 16 row left front mounted oil cooler,
Stage 4 full blend charger,
65mm PSD Alloy Toothed Belts,
G-lader serviced June 2010, oil seals and apex seals with fresh klubber grease and new gates belt.
Custom mapped at PSD about 3 years ago with all upgrade parts fitted.
Water injection kit plumbed in and built in to activate at high boost. Not wired in at the minute.
and got

its the only place to get it done in my eyes mate. Andy is the best around. I travelled a 300 mile trip to get mine done and never looked back.
Was £300 for the custom map.
Or you could take it to jabbasport and then when they drop your ecu and break it they wont do noting about it. This happened to a lad on here a few months ago.
PPP is the way forward!!

Most of the stuff you have done is pretty much as far as you can go without spending big bucks.
A cam would be good but no need for a vernier pulley if you get a schrick cam. Im sure just new INA tappets £50 would be fine with a new cam and you shouldn't have to replace the springs.
51mm tb would help as well
Front mount intercooler would help a little for mapping as the standard intercooler isn't exactly placed well. But more money and you have to get custom piping to suit.
Head flowing/porting and bigger valves and then re bore with forged psitons is only whats left really. I got my head rebuilt ported and bottom end rebuilt, bored out with forged pistons for £1500 i think. So thats an expensive route but the power gains i have no idea as i haven't had it rolling roaded. All i know is its faster than before.
Are you running toothed belts?
Agree about the toothed belts; big smiles all the way through the rev range. Really do transform the top end.
Big smiles too from a subframe if you go for handling. Probably the best single mod to your G.
Cheers for the advice jez, I expect I will start sourcing the small bits to get it mapped next year now ( injectors, I/C, bigger T/B)
I have just rebuilt my engine so I'm not too keen to do it all again with bigger internals... I'll jut see how much I can get from my standard block just hoping to get over the 160 mark may be hopefull but we'll see.
No I'm not running toothies, but I was thinking about investing in a set, what kind of effect do they have on the charger life??
Thanks.
Life on charger depends on how you drive it. If you redline it a lot and bounce it off the rev limiter you will strip belts all the time and chargers dont like it. 20k is the ideal for a rebuild on a 65mm toothed pulley.
Would be good to get and will help your power as mentioned all the way through the rev range.
I ran 150bhp with standard bottom end, standard head, Full blend charger (my r1 jabba one gave more boost by 3 psi) 65mm toothed pulley, custom ally intercooler (only one ever made, helped psi increase by 2-3), de-wedged tb, gt inlet and full stainless exhaust system and G60 injectors. My boost pressure was around 18psi then after all the work i had done by boost pressure is 12 which was expected.
I think a remap with my 1st engine would of got maybe 160bhp at a push.
Just re read your 1st post. Pretty much we had same setup and power would of been similar. Your might of been a few more horses due to the porting on head.
I think a remap would see 160bhp. Just stick a cam in it then map it.
Sorry about the late reply man I have been in London all week for the girlfriends birthday. I think I may look into a bigger I/C, Cam and Green injectors with a nice map should see some nice results.
Thanks for your advice jez
