Definitely get a fuel pump in there if you're upping the boost, most use a Walbro 255 :) I'd also get some colder rated plugs, I use NGK BKR7EIX. I ran mine at 1bar with no issues :)

Autobahn88 is a very good well priced fmic,don't need to cut the bumper to fit it and has very low pressure drop compared to a lot of other fmic's.
Rough guide to the power you can expect
Stage 2 - 280-300bhp
Free flow air filter
Free flow exhaust
Uprated fuel pump
Boost controller to acheive 1.1-1.2 bar boost pressure
Fmic
Cooler spark plugs
Super unleaded fuel

Hello mate, suggest you plan your target power 1st. Its easy to buy and then find out, you needed more. Thats going to be money down the drain.

Standard turbo will run out of puff well before then, low 300's. For that sort of power I'd be getting a GT2871R :)

Autobahn88 is a very good well priced fmic,don't need to cut the bumper to fit it and has very low pressure drop compared to a lot of other fmic's.
am about to purchase one what u think of it
he quality and fitment of this kit is similar to much more expensive fmic's on the market like Greddy, Blitz, HKS and even APS.


In most cases this front mount intercooler is larger and more efficient than the rest.
For those who want a comparison for fitting, the ab88 kit is identical to the Greddy kit.

Key features and benefits:


- Size: 600 x 300 x 76mm
- Fully polished side tanks
- Tabs on bottom and top for easy installation
- Improved Tube and Fin to increase performance efficiency by 15% over the old bar and plate design
- Intercooler inlet/outlet size: 2.5 inch O/D
- Supports 650HP max
- Fully polished alloy intercooler
- Ultra low intercooler pressure drop: 0.5-1psi at 23psi (normal bar and plate intercooler is 2.8- 4 psi at 23 psi)
- 35 % weight reduction compared to bar and plate type intercooler
- ABS and air conditioning do no not need to be relocated or removed
- Only ~9KG in total weight for the full kit
- Mikalor clamps included, absolutely NO jubilee clamps
- Full installation kit is included in the price, including mounting brackets, silicone hoses, nuts, bolts, washers, pipe work and intercoolerhe quality and fitment of this kit is similar to much more expensive fmic's on the market like Greddy, Blitz, HKS and even APS.

Yes 300+ for stock turbo. Wonder if there is any harm to go 1000cc injectors and a 300+ lph fuel pump (automotive stealth). At least they are usable should u want more later on.

Fuel pump is no different to fitting a Walbro, just costs a lot more to buy it :) Fitting 1000cc injectors is not easy, well I say that, it can be done easily if you use cheapo 1000cc side feeds which are ****e. Best bet is top feeds which means new fuel rail, fuel lines, regulator and either change the inlet manifold completely or add a spacer plate to make room :) Unless you're going for 500bhp stick to Nismo 740's :)

I'm running the same injectors as Drifter and there is absolutely no need for them unless you're aiming for 500+bhp. I will say this though, don't waste you're time with 550cc injectors, just go for 740cc Nismo's as they'll be perfect for anything from 330bhp to 450bhp

What are the main advantages of going top feed? I wanted to go top feed, was told fuel rail could fit, then found out the injectors are actually side feed. Fuel rail still fits though. But why the heck would anyone make side feed rails then...
Just want to know what I am missing out on.

You only need top feed when you need anything bigger than 740cc imo. Nismo 740's are top notch, but most side feeds that are larger than that are reworked to inject more fuel which means you get really poor spray patterns. Top feed fuel rails can fit with a standard plenum, but you need to modify the idle control valve and add a spacer plate between the upper and lower manifold to make space. You won't see any advantage over using top feeds instead of side feeds :) As for uprated fuel rails for the side feed injectors, can't see the point tbh :) Alot of the kits ou see on Ebay for top feed injectors with the rail and fittings don't fit our SR, the one I bought didn't even have the right spacings for the injectors...
